The United States Naval Medical Bulletin was first issued in April, 1907, as a means of supplying medical officers of the United States Navy with information regarding the advances which are continually being made in the medical sciences, and as a medium for the publication of accounts of special researches, observations, or experiences of individual medical officers. It is the aim of the Bureau of Medicine and Surgery to furnish in each issue special articles relating to naval medicine, descriptions of suggested devices, clinical notes on interesting cases, editorial com ments on current medical literature of special professional interest to the naval medical officer, reports from various sources, historical esays, notes and comments on topics of medical interest, and reviews or notices of the latest published medical books. The bureau extends an invitation to all medical officers to prepare and forward, with a view to publication, contributions on subjects of interest to naval medical officers. In order that each service contributor may receive due credit for his efforts in preparing matter for the Bulletin of distinct origi nality and special merit, the Surgeon General of the Navy will recom mend that a letter of commendation be forwarded to him upon the acceptance of his manuscript for publication, and that a copy of this letter be attached to his official record. The bureau does not necessarily undertake to indorse all views or opinions which may be expressed in the pages of this publication. E. R. Stitt, Surgeon General United States Navy. NOTICE TO SERVICE CONTRIBUTORS. When contributions are typewritten, double spacing and wide margins are desirable. Fasteners which can not be removed without tearing the paper are an abomination. A large proportion of the articles submitted have an official form, such as letterheads, numbered paragraphs, and needless spacing be tween paragraphs, all of which require correction before going to press. The Bulletin endeavors to follow a uniform style in headings and captions, and the editor can be spared much time and trouble and unnecessary errors can be obviated if authors will follow in the above particulars the practice of recent issues. This is not only important in special articles, but still more so in reviews. The greatest accuracy and fullness should be employed In all citations, as it has sometimes been necessary to decline articles otherwise desirable because it was impossible for the editor to understand or verify references, quotations, etc. The frequency of gross errors in orthography in many contributions Is conclusive evidence that authors often fail to read over their manuscripts after they have been typewritten. Contributions must be received two mouths prior to the date of the Issue for which they are intended. The editor is not responsible for the safe return of manuscripts and pictures. All materials supplied for illustrations, if not original, should be accompanied by a reference to the source and a statement as to whether or not reproduction has been authorized. The Bulletin intends to print only original articles, translations, in whole or in part, reviews, and reports and notices of Government or departmental activities, official announcements, etc. All original contributions are accepted on the assumption that they have not appeared previously and are not to be reprinted elsewhere without an understanding to that effect. VI U. S. NAVAL MEDICAL BULLETIN Voi. XVII. Jur.Y, 1922. No. 1. SPECIAL ARTICLES. THE SANITARY INSPECTOR OF THE COMMUNITY. By W. H. Bell, Captain, Medical Corps, United States Navy. " Without responsibility there can be no efficiency; Without efficiency success can only be accidental." It may be said without fear of contradiction that one indication of the spirit of the times is the mobilization of every form of science in an effort to contribute to human progress and efficiency. The tendency to reach into the realms of science for additional facts or the discovery of new principles has been stimulated by the assurance of their speedy application to the solution of various problems of everyday life. The recent war has given an impetus to this spirit of investigation, and by it alone may the world "ex pect ultimately to overcome the telling advantages, both in war and peace, which Germany long enjoyed because of the organization and development of her scientific resources." Every form of scientific research is important in building the firm foundation upon which enduring advances depwid. Thus, " Euclid, working out problems in pure mathematics in Alexandria, prepared the way for the calculations of the engineer. Galileo, discovering the satellites of Jupiter, convinced the world of the truth of the Co- pernican theory, broke down absurd medieval conceptions which prevented scientific progress, and stimulated exploration and ad vance in every field. Pasteur, studying the optical properties of certain crystals, with no thought of practical result, was led to his investigations of bacteria and his epoch-making discoveries for the benefit of mankind." Not only are scientific bodies organizing their educational and research resources in the interest of efficiency, but teaching and re search institutions are arranging their facilities along lines calcu lated to foster progress in a precise and effective fashion. Every where one notes the attempt to overcome the sluggishness with which the public receives and applies scientific information, and by the word "public" we mean the individuals who compose military as l 2 BELL SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII. well as civil communities. It has long been noted that whatever a military organization may be considered to gain by virtue of au thority is often lost in the persistence of a traditional conservatism, a conservatism which is often expressed as a resistance to reforms. This resistance is found in civil as well as military communities and is the factor which prompts reformers to exaggerate the conditions which are under consideration in order to emphasize the necessity of reform. It is difficult, however, to exaggerate the ill and far-reaching con sequences of a disregard to the dictates of health. Yet they are often so subtle and intangible to the average citizen who can not readily connect an obscure cause with possibly an unseen effect, that efforts to didactically impress the public with the necessity of precautions regarding public health are often futile. The mind is so constituted that unfortunately the value of experience derived from some public disaster is soon forgotten, and no matter how good the intention may be to continue preventive measures in the future, they often degen erate into a routine and then pass into oblivion. So discouraging an outlook does this suggest and so often has it been the stumblingblock to adequate and timely preparation for the prevention of public calamities, that the development of a pre ventable disaster is frequently a needed object lesson to arouse pub lic interest in matters pertaining to public health. It is particularly in connection with matters relating to hygiene and sanitation that cause and effect are not apparent to the average individual who at the present time has not been educated up to a satisfactory appreciation of the value of public-health measures. His education is a huge task, to be completed by various means, one of which forms the subject of this paper, namely, the sanitary in spector of the community. It may be interesting and helpful at this point to outline briefly the development of the science of sanitation from an educational view point and to review the facilities at present available to students who aim to make public health their life work. As early as 1865 the Medical College of the New York Infirmary for Women and Children made hygiene and public sanitation a com pulsory part of its curriculum. Even before this the Woman's Medical College of Pennsylvania had taught hygiene in connection with physiology. The University of Michigan, when its medical department was founded in 1850, taught the principles of the analysis of drinking water to its students, and in the early seventies lectures on hygiene were given not only to medical students but to others, including those taking the classical course. Later, in 1876, a course of lectures was established, with the professor of hygiene in charge. In connection with pathology or clinical subjects, as early as 1881, No. 1. BELL SANITARY INSPECTOR OF THE COMMUNITY. 3 Western Reserve, in Cleveland, Ohio, taught state, or as it is now termed, preventive medicine and hygiene. At Harvard, lectures on hygiene were instituted in 1876. In 1892 the Institute of Hygiene of the University of Pennsylvania was established. Foundations for the financing of instruction in hygiene were likewise provided in other medical schools, such as the University of California and Cooper Medical School, in San Francisco. The department of hygiene in the latter institution, now Leland Stanford, gave way to the depart ment of bacteriology. Not long ago Western Reserve recognized the importance of hygiene and appointed a full-time professor in this branch. A similar change took place at Yale and at the University of Chicago. With all this, hygiene as a major subject, with a trained scientist giving his entire time to studying its problems and teaching its principles, until recently existed in but 6 of the 38 reputable medical schools in the United States. This was not a highly creditable showing in comparison, for ex ample, with Germany, where all of the 22 universities teaching medicine had their hygiene institutes, or with Great Britain, where every graduate in medicine must have followed a course in public health, and passed an examination in it. This state of affairs in the United States was, perhaps, only a reflection of the apathetic public sentiment which seemed content that its interests in health require ments should be supervised in the main by so-called " part-time " health officers — often politicians, appointed without regard to fitness for the office they were expected to fill—and with such inadequate recompense as to inspire a primary interest in their original gainful occupation as a means to livelihood. This vicious practice is still too prevalent; but better things are coming to pass, though we are a long way from realizing practically all that our scientific knowl edge makes possible. The methods of handling health conditions are changing and they began to change with marked strides even before the World War gave such an impetus to the public-health movement. Strong and able men and women are behind this movement and the public is opening its eyes and its purse with the realization that there are grave facts to be faced with intelligence and honesty, and that there is much of an intangible nature and remote benefit that is worth paying for in advance of delivery. In preparation for the proper utilization of this awakened public understanding and the scientific economic disbursement of funds allotted, as a result of the growing confidence in public-health under takings, the idea of developing personnel to handle this tremendously important work is taking practical form. The study of disease and its prevention has always come within the province of the doctor of medicine, but in this new field of endeavor—the care of the health of a community—there is room 4 BELL SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII for other workers whose objective also is " the study of health and how to maintain it." Much is being done by various powerful agencies such as the United States Public Health Service, the Medical Departments of the Army and Navy, health departments of large cities, and educa tional institutions to lift our knowledge of preventive medicine out of the realm of the casual and to make the use of it the general prac tice of individuals and communities, to educate the public up to a full understanding of its responsibility regarding preventive medi cine, and to build up a body of public-health workers, men and women whose efforts are devoted to the prevention of disease. The requirements of the health official are to-day receiving most careful attention by such men as Sedgwich, Reinhardt, Whipple, Rosenau, and Overton, and out of a recognized necessity not only are books on the subject being written but special schools with graded courses are being established for instruction in this subject. In July, 1915, Rosenau stated that "hygiene is included as a major subject in the curriculum of only three medical schools in this country, namely, the University of Pennsylvania, the University of Michigan, and Harvard." On the other hand, Reinhardt in February, 1913, with regard to the division between preparation for preventive and cura tive medicine, stated : " The division has evidently come to stay, be cause it is recognized and provided for in some of the best institu tions of learning in our country; in Harvard, in the Universities of Pennsylvania, Wisconsin, and Michigan complete and separate courses are given to students who attain the degree of M. D. (doctor of medicine) and the degree of D. P. H. (doctor or diploma of pub lic health). Johns Hopkins University also has a school of hygiene and public health. Although the University of California has no degree in public health, nor as yet any definite course leading to the degree in public health, it is rapidly working to that end and has long supplied courses adequate for the need of general students. It will perhaps be interesting, and in connection with the development of schools of public health it is pertinent, to note that " what is vir tually a certificate of public health (based upon methodical and ap propriate courses) was established in Lyon, France, as early as 1905, and that, in 1919, 209 persons had received the certificate, 135 having been physicians or medical students and 74 nonmedical men—phar macists, chemists, architects, engineers, etc."1 In the United States the school for health officers conducted by Harvard University and the Massachusetts Institute of Technology represents the greatest and most substantial step in this direction, and ' Rosenau, Journal A. M. A., Vol. LXV, No. 4, p. 321 ; Reinhardt, Journal A. M. A.. Vol. LX, No. 6, p. 427; Sedgwich, W. T., Am. Jour, of Public Health, Vol. X, No. 4, P. 352. Ko. 1. BELL SANITARY INSPECTOR OF THE COMMUNITY. 5 at present awards a certificate of public health (C. P. H.). A doc torate of public health (D. P. H.) is conferred in connection with the training at this school of Harvard University as one of its highest degrees. "The primary object of the school for health officers is to provide the scientific groundwork in the sanitary sciences which un derlies efficient health administration,"2 for satisfactory practical work is done and economically done only " by those who have a secure scientific foundation." The school recognizes, it is understood, four general subdivisions of the field of public service for which it under takes to train, viz, the teacher, the research scholar, the technical ex pert, and the administrator. The scope of the training for the tech nical expert is perhaps comprehensive enough to include what may be termed the sanitary agent and the district health inspector, but the requirements for admission to, and the required period of study within, the school exacted of candidates for even its lowest award, the C. P. H., are such as to exclude the class from which are recruited the grade of public health servant at present so largely depended upon for the details of field inspection and work —the grade of public health servant which constitutes the sense bulb of the ultimate rami fication of public health organizations. I refer to the corps of field workers which comes in daily contact with the people of a commu nity as the representative of health departments in their effort to secure general recognition of health dictates and obedience to health laws. As above indicated, much has been and is being done to develop a competent personnel in the upper stratas of health organizations ; but it seems that little well-directed or systematic attention has been, or is being, given to the question of creating a high-toned, efficient, and dependable corps of sanitary inspectors, or of making the remunera tion sufficiently attractive to assist such creation. It has been esti mated by Farrell3 that fully 7,000 sanitary inspectors are required for work throughout the United States on the basis of a conservative minimum organization of public health units per 20,000 of popula tion. This would be independent of special problems and under takings. Little or nothing has been written in this country touching the peculiar requirements as to fitness, training, and service of those who would fill this office. I have looked almost in vain, outside of English publications, for anything except the most superficial outline of daily general routine duties.4 ■Rosenau, Journal A. M. A., Vol. L.XIV, No. 10, p. 795. ■Farrell, J. A., Jonrnal A. M. A., Vol. 77, No. 7, Aug. 13, 1921, p. 514. 'For example, Frank Stockman says In the chapter on "Duties of sanitary Inspectors In London," in his Practical Guide for Sanitary Inspectors : 1. Must obey and carry out Instructions and directions of sanitary authority. 2. Must attend meetings as required by sanitary authorities. Should report at these meetings all matters requiring action, etc. (Footnote continued on p. 6.) 6 BELL SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII. Yet these people bear the same relation to the doctor of preventive medicine as does the nurse to the doctor of curative medicine and are quite as important in the scheme of things. They represent adminis trative assistance reduced to its lowest possible equation, but which is none the less indispensable as a factor depended upon for results in the distal reaches of a health department's daily concerns. A sanitary inspector is anything but a theorist. His business is the observation of things as they are and the collection of information which shall reflect facts. The success of any system of sanitation or organization in the interest of public health, assuming it is well directed, will in the last analysis depend upon the type, training, and general efficiency of subordinates, the thoroughness with which they have been indoctrinated in the aims of the institution and their enthusiastic, persevering fidelity to the objective. The aim of all health organizations is, definitely and broadly, the physical and mental improvement of the human race—the pro gressive recognition, establishment, and observance of the utmost any given time in the interest of health, as a thing in itself, and as the basis of all that spells the best in life. Contributions to civic betterment in any and every direction should be one of the aspira tions in the breast of every worthy member of society. It is from such an element that we should seek to recruit sanitary inspectors. Unfortunately in the present state of our progress and facilities these are in the main without special training. Dependence for sanitary aides in civil life, by virture of inadequate compensation, has been upon a class of citizens less self-respecting and less conscious of its responsibilities than is desirable. This fact has suggested the very attractive proposition that the staff of visiting nurses which is a part of every properly organized health establishment be enlarged and given the additional duties of sanitary inspectors 5 or that sani- (Continued from p. 5.) 3.

" She Is an Inspector and instructor of persons, while the sanitary inspector deals with their environ ment," but you can't, get away from the one in dealing with the other. No. 1. BELL —SANITARY INSPECTOB OF THE COMMUNITY. 7 tary inspectors be carefully selected from the female citizens of a community. In either case the services of those who by nature or early training are "housekeepers" are secured. In the first case the advantage of fortifying the duty of exacting, with the persuasive influence of service, would be realized as an asset in getting results. but whatever the source of personnel for this service, when there is combined with the general aspiration of good citizenship, an iden tification with a calling of vital moment to the welfare of society in one specific direction, nothing which will add to the mental equip ment, fire enthusiasm, and fix determination to devote the very best efforts to the work in hand, can be neglected by the individual in office. " He must be alive to conditions, awake to discoveries, and conversant with the success or failure of methods in other localities ; he can better afford to lag behind the science of which he is an ex ponent, but should be ambitious to hasten its advancement; this ho can accomplish if he will dignify his least undertaking as a definite problem in research." It is the small things that count in building up big results just as the wonderful creation represented by the liv ing body is made up of billions of little cells. Each sanitary inspec tor may be likened to an individual cell of an organ, and, as in the living body, the well-being of the whole depends upon the perfec tion with which the heart, liver, and kidneys perform their functions, both individually and in relation to one another, so the effectiveness of a given health department depends upon the perfection with which the corps of sanitary inspectors does its particular work in coopera tion with other divisions of the department concerned. It is the administrative possibilities in the make-up of a sanitary inspector that count so much in rating his efficiency, for he alone comes in daily contact with the individuals of a community. Before taking up the several points I have in mind let us analyze and give practical meaning to the term " sanitary inspector." In do ing so I will take the last word first and change its form from " in spector " to " inspection." " Inspector " is a designation of office, a title; "inspection" represents the execution —the function which is the realization of the office. What does it mean ? It means a routine periodic or a special investigation of operations or conditions to ascertain whether or not the subject of the inspection is as the best interests of all concerned dictate that it should be. And what is its purpose? Its purpose is to obtain periodically assurance that all is right, or to learn definitely what is wrong, and, in the first case, to commend and encourage the responsible parties to continue effort and, in the second case, to guide and urge to better effort and to cor 8 BELL—SANITAKY IKSPECTOK OF THE COMMUNITY. Vol. XVII rect the fault in one way or another, immediately if possible, but cer tainly by starting the necessary corrective machinery. The psychologic understanding with which the function of inspec tion is entered upon, or the lack of it, and the spirit with which it is carried out when human contacts are involved, spell success or failure. What are apt to be the results if the inspection is undertaken in a spirit of gruff destructive criticism with a crude display of au thority? In the first place we note resistance which essentially is opposed to one's best interests —opposed to the work in hand—to one's reputation as an official of the sanitary department. Every body within the field of the inspection will assume the defensive, and tenaciously withhold that information or cooperation so essen tial to success in securing the desired results. And thereafter will follow a long train of ill consequences in comparison with which failure, and the importance of it to one personally, fades into insig nificance. An insanitary condition and the spread of preventable disease entails far-reaching damage to the community. The benefit or damage, as the case may be, to the community and to oneself runs parallel and is effected by the same end result. What, on the other hand, are apt to be the results of the inspec tion if undertaken in a spirit of kindly constructive criticism and helpfulness with tactful firmness based on precise knowledge as the only show of force ? In the first place, respect for and sympathy with the aims of the office will be noted. The sanitary inspector comes in direct contact with the individuals of his field of responsi bility and must take their varying religious and racial susceptibili ties, customs of life, and temperamental and habit tendencies into account. He is the one who must carry the health propaganda tcy the home not only by word but by objective teaching. The secondary rewards earned by a proper spirit and bearing in carrying out the duty of inspection, and which are a direct product of the respect and sympathy thus won, are the helpful cooperation of the individ uals inspected, and their open and frank response to inquiry in all matters of concern to the inspector. Many inspectors fail because they promptly kill the goose that lays the golden egg—their source of information —by improper methods. The true criterion of efficient general sanitary inspection is not the number of reports of nuisances or violations of the law that are turned into headquarters, but the health of the district a given in spector may be assigned to supervise as shown by statistics from month to month, or, to take for example an inspection in which special training and experience is necessary, such as the inspection of a dairy farm, the criterion of efficient inspection is the maintenance of the required standard of the dairy product as shown by labora tory examination. Of course reports have to be made, and they serve the important purpose of showing conditions as they exist, and No. 1. BELL—SANITARY INSPECTOR OF THE COMMUNITY. 9 of bringing to one's assistance the power of higher authority, but I want to keep away from the idea that they are more than a small part of the full duty of the office. I want to avoid the possible false notion that the fulfillment of the obligation of the office is the sum total of unfavorable criticism and the unearthing of some culpable error or omission. It is the part of administrative wisdom, rather, to> loot for evidence of compliance with the sanitary code and general sanitary principles, taking careful note the while of those features in which there seems opportunity for improvement, and to look with surprise upon failure to render that measure of cooperation which is to be expected from those possessed of intelligence and honest purpose. Occasionally one will be called upon to exercise all the force resident in the office but, in general, the aim should be to- lead rather than to drive. When there are adequate laws and ade quate authority, force is the shortest road to a desired action, but. there are few laws perfect enough to admit the elimination of dis cretion or that do not present some loop hole of escape—some defect which can be taken advantage of for purposes of evasion. The work of the inspector, therefore, is in part a campaign of education, to convert a community to sanitary living and, as in religion or pol itics, it is impossible to convert by force. And now as to the word " sanitary," which precedes the word " in spector " and completes the title : It stands for that condition of our surroundings, immediate and remote, which conduces to physical well being, and brings contentment and happiness, not only as a re flection of a state of health1 but by preserving unstained and unmarred the native beauty of Gtfd's gifts. Furthermore, the word " sanitary " represents a conditjio^ upon which is based the possibilities of progress- and accomplishme$i;,)in all those enterprises wherein human energy is a determining factor. The title " sanitary inspector " is one of which to be proud, and it designates an office which is growing in importance. Indeed, it has become a specialty within a profession dignified by its identification with the great undertakings in tropical latitudes during recent years. Cuba would not be to-day the well-ordered, prosperous country that it is if the work of the sanitary inspector had been faulty. The Panama Canal would not be to-day accommodating the ocean traffic of the world if the sanitary inspector had been unequal to the task intrusted to him. Each of the 25 districts into which the Canal Zone was divided, as far as general sanitary work was concerned, was in charge of a sanitary inspector who had under his control a properly trained body of men, consisting of from 20 to 100 laborers, with as sistants and foremen as necessary.8 " No case of yellow fever, small pox, or plague originated in or was brought to the Isthmus during the • Gorgas, W. C, Sanitation in Panama, 1915. D. Appleton k Co., " The work of the unitary inspector," p. 182. 10 BELL—SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII month." This represented the usual statement of the chief sanitary officer in his monthly report upon health conditions during the con struction of the canal and reflected the work of the sanitary inspector. The obvious duties of the sanitary inspector will vary according to locality, season, and peoples. The difficulties in executing these duties will increase or decrease according to the temper of the com munity collectively, and that of the individual families composing it regardless of the personality of the inspector. In the Tropics, foi example, the duties are concerned, to a large extent, with the contro of protozoal diseases, whereas in northern climates, except in malarin districts, the bacterial diseases constitute the burden of concern Urban communities present quite different requirements from thost of rural settlements; manufacturing centers present sanitary prob lems distinct from those of business or purely residential districts and peoples of different races and religions present superstitions 01 habits or rites each of which, in its own way, imposes new and per haps peculiar duties, or the exercise of ingenuity, to the end that thi inherent violation of sanitary principles may be overcome with en tire deference to religious or ritual considerations.7 As an example of the general outline of duties which are formu lated and issued for the guidance of sanitary inspectors, I quote th prescription " by the local government board for sanitary inspector in the metropolis, in the sanitary officer's (London) order dated De cember 8, 1891." 1. He shall perform, either under the speclaj! directions of the sanitar; authority, or so far as authorized by the sanitary authority, under the dire< tions of the medical officer of health, or, in cases where no such directions ai required, without such directions, all the duties specially imposed upon a san tary inspector by any statute or statutes, or by the oWers issued by us, s far as the same apply to his office. (>*•)'' 2. He shall attend all meetings of the sanitary authority when so required. 3. He shall by Inspection of his district, both ■systematically at certal periods, and at Intervals as occasion may require, keep himself informed i respect of the nuisances existing therein that require abatement. 4. On receiving notice of the existence of any nuisance within his district, t of the breach of any by-laws or regulations made by the sanitary authority f< the suppression of nuisances, of any by-laws made by the London County Cou cil which it is the duty of the sanitary authority to enforce, he shall, as ear as practicable, visit the spot and inquire into such alleged nuisance or breai of by-laws or regulations. 5.

He shall from time to time, and forthwith upon complaint, visit and Inspect the shops and places in which is exposed for sale, or in which is deposited for the purpose of sale or of preparation for sale, any animal, or any article, whether solid or liquid, intended for the food of man, and examine any such animal or article which may be therein. If any such animal or article appears to him to be diseased or unsound or unwholesome or unfit for the food of man, he shall seize and carry away the same himself or by an assistant, in order to have the same dealt with by a justice according to the provisions of section 47 of the public health (London) act, 1891 : Provided, That, In any case of doubt arising under this clause, he shall report the matter to the medical officer of health, with the view of obtaining his advice thereon. 7. He shall, when and as directed by the sanitary authority, procure and submit samples of food, drink, or drugs suspected to be adulterated to be analyzed by the analyst appointed under the sale of food and drugs act, 1875, and upon receiving a certificate stating that the articles of food, drink, or drugs are adulterated, cause a complaint to be made, and take the other proceedings prescribed by the act. 8. Whenever it appears to him that the Intervention of the medical officer of health Is necessary in connection with any nuisance, he shall forthwith inform such officer thereof. He shall also, subject to the directions of the sanitary authority, attend to the instructions of the medical officer of health with respect to any measures which can be lawfully taken by a sanitary inspector Tinder the public health (London) act, 1891, or under any other statute or statutes. 9. He shall enter from day to day, in a book to be provided by the sanitary authority, particulars of his inspections and of the action taken by him in the execution of his duties. He shall also keep a book or books, to be provided by the sanitary authority, so arranged as to form, as far as possible, a continuous record of the sanitary condition of each of the premises in respect of which any action has been taken under the public health (London) net, 1891, or under any other statute or statutes, and shall keep any other systematic records that the sanitary authority may require. 10. He shall at all reasonable times, when applied to by the medical officer of ■health, produce to htm his books or any of them, and render to him such Information as he may be able to furnish with respect to any matter to which the duties of a sanitary inspector relate. 11. He shall, if directed by the sanitary authority to do so, superintend and see to the due execution of all works which may be undertaken under their direction for the suppression or removal of nuisances within his district. 12. In matters not specifically provided for in this order he shall observe and execute any instructions issued by us, and the lawful orders and directions of the sanitary authority, applicable to this office. Another example of later date is given by Porter.* These are prescribed in the order of 1910, which details the duties of the medical officer of health, which, in some respects, they resem ble. He is required— 1. To perform all duties imposed upon inspectors by the public health act, 1875, and other statutes. 2. To attend meetings of the sanitary authorities when required.

It frequently happens, of course, that sanitary inspectors are assigned to special fields which absorb their whole time, at the expense of attention to the duties of the general inspection above indicated, and in which the}' must become experts. This brings me to the character and peculiar fitness requirements of the office, and as an introduction to this section of my paper I quote from The Sanitary Inspector's Handbook, by Albert Taylor (London, 1914). 9 In general terms, a person to be fully competent to perform the duties of a sanitary inspector should have the following qualifications : He should be the owner of a good, sound constitution and be able to follow the rules laid down to preserve it, including temperance. He should be able to write legibly, spell correctly, and have a fair knowledge of arithmetic. » The preface to the last edition Bays that this book was compiled with the desire of furnishing to the sanitary inspector and those seeking to qualify for such appointment a useful vade mecum upon the subjects pertaining to the office. The book aims to supply practical Information on the various matters which come dally under the notice of the sanitary Inspector, and not at being an exhaustive work of scientific reference. As it la> In Its fifth edition, it would seem that the book has met a demand and filled a useful purpose. No.1. 13 BELL—SANITAKY INSPECTOR OF THE COMMUNITY. He should have a thorough knowledge of building construction, including plumbing, and the methods of water supply and drainage; also the proper principles of ventilation of rooms, and should know the best and most suitable sanitary appliances to use under varied circumstances. He should have an observant eye, a quick ear, and a sensitive nose, and be able to detect any defective or faulty sanitary arrangements of dwellings and other buildings. He should be thoroughly acquainted with the provisions of the various public health acts and model by-laws relative to the duties of sanitary inspectors. He must make himself acquainted with the various kinds of infectious dis eases and know the best means to adopt for preventing the spread of such diseases. He should acquire a knowledge of the different kinds of disinfectants in use and know those best fitted for safely and effectually disinfecting bouses and fever localities. He should have a thorough knowledge as to the different methods adopted for the collection and disposal of house and other refuse. ' He should be of pleasing address, and in ids dealing with the public he should be calm and collected, learn to restrain his temper, and to endure hard speeches. He should bear himself with a sympathetic aspect to the many bereaved widows, mothers, and orphan children he so frequently meets in the per formance of his duties. Civility and kindness must characterize all his actions, and rude behavior or supercilious officialism should find no place In his conduct. He should at all times attend promptly to any special complaints, and frequent inspections at irregular periods are necessary as regards slaughterhouses and other similar businesses. Sanitary authorities are sometimes disposed to disregard anonymous com plaints, but it Is the duty of the authority to investigate every specific com plaint made to them without regard to the means by which it comes to their knowledge; and, if satisfied, upon Inquiry, that such complaints are justified, they should direct that measures be taken to remove the ground of complaint. It is essential, however, to exercise the greatest care when inquiring into such complaints, otherwise the authority and its inspector may be made the victim of ill-will or spite. Speaking from the Engish point of view again, and in a rather quaint vein, as indicating great expectations and the extremely large order that some in authority were wont to impose upon the occupant of a hitherto miserably compensated office, it has been said, " That in order to carry out the multifarious duties of his office, an inspector should be partially educated in the following trades and professions, viz, that of a plumber, in order to detect bad work and be able to fill in his notices how the bad work is to be rectified ; that of a butcher, in order to detect and intercept bad meat; that of a veteri nary surgeon, in order to observe animals that may be suffering under the contagious diseases (animals) act, and also in connection with his visits to slaughterhouses ; that of a lawyer, in order that he may he well cognizant with all the acts and regulations under which he carries out his duties, and to enable him to form a judicial opinion upon all statements of facts; that of an architect, in order that he •Day understand plans, and, if necessary, make sketches of anything 14 BELL—SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII. that comes under his notice in connection -with his duties; that of a clergyman, in order that he may preach the good tidings of sanita tion, and may by his precept and example further the good work he is engaged upon, and also that he may be able to patiently bear the abuse which he may sometimes receive for what is called his ' prying interference.' Lastly, he must try to educate himself in common sense —that most valuable commodity without which book learning availeth not much." Discussing the character and temperament of the sanitary inspec tor, Taylor 10 says : " To carry out his duties efficiently, the sanitary inspector must exercise great forbearance, tact, and good temper ; sometimes technical objections will be raised to his proceedings; vexations, delays, and evasions will often occur in the fulfillment of his notices ; nuisances, which the officer is anxious to suppress, may elude his authority; when he would force one person to refrain from tainting the atmos phere with the result that his tenants were better housed than cattle, he will often be reminded of the rights of property and of an Eng lishman's inviolable claim to do as he will with his own. " With private affairs he should interfere only when they become of public import, and with private liberty only when it becomes a public encroachment. " Thus neither the personality nor the office should be magnified. To do this is to court the contempt of ordinary men and women. Officialdom is the curse of any administrative body. Therefore, the man who goes about his duties in a way that compels respect, and whose tactful demeanor impresses others that the thing he is asking for can not be denied, is the one who will win his way to the front Owners and occupiers are but human, and they like to feel they are receiving the attention of a friend although an official." And again, on page 38 of his book, Taylor says under the heading " Qualifications " : " Sanitary authorities do not and have not always sought to ap point the person best fitted for the post of inspector. They have too frequently appointed the man who could command the greatest influence with its members without the slightest regard to his qualifi cations. The important duties which sanitary inspectors are now called upon to discharge, and the large discretionary power that must be vested in them, demand that only qualified persons should receive these appointments, and experience has undoubtedly rendered it necessary to establish some mode of testing the competency and qualifications of persons offering themselves as candidates to fill such appointments. Some assurance should be given to the public that "Taylor, Albert, Sanitary Inspector's Handbook, London, 1914, p. 38. No. 1. 15 BELL—SANITARY INSPECTOR OF THE COMMUNITY. the persons entrusted with these responsible duties are properly qualified. " Evidence of special training and of potential efficiency as repre sented by character and temperament ought to be regarded as basic, and when the question of qualifications has been thus determined and appointment has been made, a fixity of tenure should obtain. " Every sanitary inspector is entitled to security of office, for he it is who is brought into personal conflict with property owners more than any other officer appointed by the local authority." The Secretary of Health and Charities in Cuba, speaking of his local chief sanitary officers, said: "They can all feel perfectly sure that they will not be removed from their offices while they comply with their duties in a satisfactory manner, because I sustain the view that the employee who fulfills his obligations competently should be respected, defended, and protected." Needless to say, definite knowledge on a variety of subjects is of the utmost importance, but the best professional equipment may be a total loss if its possessor lacks a personality which is considered essential to the effective application of such knowledge. In seeking to outline the right personality I am conscious of dealing with the main factor in success. Indeed, so clearly is this the case, that if something in one or the other qualifications must be sacrificed in the candidate it had better be in the direction of technical training. Professional shortcomings can be more easily corrected than defects in personality. The difficulties and perplexities which beset a conscientious in spector are rarely mentioned or are insufficiently dwelt upon by the instructors in sanitary science who are primarily interested in the technicalities of this or that particular subject, and who may be merely preparing students for examination. This fact the inspector may be sure of, namely, that to frame requirements is one thing, and to see that they are carried out is quite another. There is no doubt many who, through luck of serious intention, through laziness, men tal or physical, or through sheer lack of ability and perception, skim along lightly over things and avoid annoyance and difficulties but effect nothing. Others fail for want of adequate training; for want of a sanitary point of view, a sanitary interest and ambition, sanitary ideal, and a sufficient acquaintance with sanitary problems or satis factory practical methods of solving them. Ingenuity and resource fulness, which are so imperative, are to such a group total strangers. But the vast majority who find employment as sanitary inspectors, and are appointed without regard to their qualifications, fail to do more than to keep their own skirts clean —fail to realize the reward of perhaps an honest ambition and purpose because they are not tem peramentally constituted to be a telling figure in that field of work. 16 BELL SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII What sort of personality fits the job and makes for its utmost possi bilities ? It is impossible to lay down any bard and fast rules or to treat this phase of the subject briefly. It finds concentrated expres sion in the thought that once an inspector succeeds in persuading the people to accept him as a friend, working as much in their inter est individually as in the public welfare—even though a friend who tells home truths— the battle is largely won. Difficulties there will always be under the best of circumstances, difficulties which may have been increased by want of wisdom or tact on the part of a prede cessor, but the gratification of a victory in spite of them is great, and the self-satisfying consciousness that something positive is really being accomplished —that progress is being made through one's personal effects—is a large reward. A number of contributors to the literature of public-health work have touched upon the element of personality in the make-up of sanitary inspectors, but the one giving most systematic and sym pathetic consideration to it is Edith L. Maynard in her book entitled " Women in the Public Health Service." It is written from the English point of view, as is the case of most of the literature on the subject, but it is not the less applicable to either men or women in field work anywhere, and so nearly expresses my own views tbat in the following paragraphs I have drawn largely upon it. " It must be borne in mind that public-health work of whatever sort consists mainly in trying to make people do what, if left to themselves, they would not do." The bringing about of a new order of things, then, is the real crux of the task, and it should appeal to one's sporting nature. It is a contest as to which shall win —the exponent of progress or of the obsolete — and its very difficulties and tenacity of purpose is a characteristic of women which men will do well to imitate, and it is particularly necessary to the reformer in the guise of a sanitary inspector, for he can not afford to compromise with principle. He can do so only as a means to an end. In other words, if a thing can't be done one way, it can be done in another way, and it is the inspector's duty to be practical —to familiarize himself with all the details involved in a given problem and to find reasonable means for meeting reasonable objections. It is a matter of managing people, of exerting and proving oneself in the most inter esting game imaginable, and " it is not everyone who can deal satis factorily with others." Owing to the variety of classes and racial peculiarities or habits and shades of self-conscious social caste that will be met in the course of the day's work, the background of the inspector, in other than the mere matter of education, is not an inconsiderable item in the total making for potential efficiency. The environment from which he is No. 1. BELL—SANITARY INSPECTOR OF THE COMMUNITY. 17 drawn is important and should be such as to give promise that he possesses that savoir faire which will make it possible for him to dis cern both the nature of a situation and its opportunities or impedi ments. He should entertain a sense of the importance of his work and assume the quiet dignity and full measure of responsibility which properly attaches to his office, but he should be 'one who has found himself, in a worldly-wise sense, and is not disposed either to take himself too seriously or to patronize those with whom he comes in contact. There must be a nice appreciation of ethical relation ships as shown in his bearings and intercourse. "But this, obvi ously, is not enough, for there are people of all classes who have the (unhappy) knack of rubbing others up the wrong way, and such an one is of no use in the Public Health Service." "To whatever class the public-health officer belongs, he must possess tact. The tactful official will quickly ascertain the frame of mind of those whom he visits, will know when to praise and when to blame, when to be firm and when to use persuasion only. Many un pleasant truths will have to be told if the work is to be effective, but he will know how to take the sting out of them. He will possess that true sympathy which understands the greatest difficulties which are in the way of those who would endeavor to rise above their often debasing surroundings. But weakness is quite another thing, and there is no place in public-health work for such a characteristic. It is uphill work all the time, and the worker must possess the strength of mind which will enable him to persevere in spite of the most dis heartening results of his efforts." Determination and patience therefore are also essential. In the exercise of these qualities the inspector should know whereof he speaks: he should be sure that the knowledge of his subject is pre cise. Glittering generalities sound well, but they do not leave as deep an impression on those he seeks to guide as do simple instructions given in a manner at once kindly and convincing, which seems to invite rather than compel cooperation. In this connection too much stress can not be laid upon the importance of demonstration and memoranda. Whenever possible, resort should be made to object les sons, and written instruction expressed in the simplest phrases should be given, because, however well intentioned, people will forget, and the mere fact that they are being called upon to do something strange or unusual fosters that unfortunate trick of the mind— forgetful- ness. The need of patient repetition will be realized when the well- nigh universal resistance to any change from an old order of things which has become the habit of life is taken into account. People get into a groove and the older they grow the deeper that groove be comes and the harder it is to get them out of it. Because they have 18 BELL—SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVIt done a particular thing a certain way for years they rebel against having a new way of doing that same thing imposed upon them. For this and other reasons the credulous person will not accom plish much. Deception will be met with daily in almost every branch, of the work, and the inspector must be observant, critical, accurate, and thorough. Nor does the " cocksure," self-opinionated individual usually go very far. It is necessary for the inspector "to keep an open mind as to the methods of work and to look out for opportuni ties of learning from those engaged in the various branches of social service as well as from others in his own profession. A constant effort will have to be made against becoming stereotyped in either methods or ideas, and the public-health worker, above all others, needs to remind himself frequently that the work of his department, important though it is, is only part of a great endeavor which is: being made in many directions, by multifarious agencies, toward social amelioration. If, therefore, the inspector is to be saved from- isolation and incompetency, he must contrive to keep in touch with other agencies, learn their aims and methods, and look out for every opportunity to cooperate." Furthermore, the inspector must be self-controlled. An " easy-go- ing" person will never make progress, but a bad-tempered person will always be getting into difficulties and stultifying the effect of work which otherwise might have been valuable. There i& ample cause for annoyance and irritation. Indeed, "the inspector may look for any sort of treatment —quiet patronage, insolent opposition^, irritable impatience at disturbance, a quiet acceptance of inspection as one of the ills of life, or a marked anxiety to please." His tem per must be controlled throughout, and an endeavor to see the point of view of the one responsible for the condition or property under inspection will make compliance with this injunction easier. "It is: by no means a pleasant thing to be inspected. The interruption alone is a serious annoyance to a busy person and the very fact of possess ing the right of entry should make the official all the more careful to treat the occupier courteously and respectfully. This is quite com patible with a quiet dignity. In most cases the work can be car ried out without friction if this is borne in mind. It is not always- easy for an employer to keep discipline among workers, and the dif ficulty will be increased if an inspector walks into a premises as if' it belonged to him and speaks autocratically to the occupier before the workpeople. It is always best to act as if it were taken for granted that everything would be found in due order. The major ity of occupiers err through ignorance, or carelessness, or press of " work, and are often quite unable to grasp the necessity of the legal-: standard." No. 1. BELL—SANITARY INSPECTOR OF THE COMMUNITY. 1$ Again, no one who is dependent upon direct orders as a basis for his activities will ever "get through more than 'jog-trot' routine work." Success in the office demands initiative and resourcefulness for situations constantly arise requiring action without opportunity for reference to higher authority, and the inspector can not afford to appear incompetent in emergencies. Serious trouble can often be averted through quick decision and rapid action, and failure in this direction may also lower the service in the eyes of the public. Not only are the requirements exacting as regards the tempera mental make-up of the individual, but the need " for good health must be emphatically emphasized. The work is extremely hard ; it involves a mental as well as a physical strain and makes demands upon the strongest." Mere freedom from organized disorder is not enough. Finally the disposition of the inspector should be such as to teach by example as well as precept. The development of a health con science in the public is a progression hoped for as an asset to public- health organizations—to the inspector in facilitating his work— and every sanitary inspector should be a nucleus of enthusiasm for the health propaganda and spread an understanding of its principles throughout his district. But in doing so he must remember that acts speak louder and carry greater force and conviction than words. His own personal appearance and the conduct of his own life and surroundings must therefore illustrate his advice. As regards general education and special training, others have spoken and will speak. This phase of the question of fitness was not contemplated in the discussion planned for this paper other than to touch upon the need, as has already been done, for a wider insist ence upon the degree of fitness represented by a certificate or diploma on sanitary sciences. It is perhaps sufficient to say here that, both in general and technical education, the highest is none too good if the inspector is to be able to enter intelligently into the wider aspects of his work and is to perform satisfactorily the various duties that may be properly imposed upon him, to say nothing about the im portance of well-written letters and reports, an understanding of statistics and usefulness of a working knowledge of languages other than his own. " It is certain also that every public-health worker will be called upon sooner or later to speak in public. It may be only to give a 'friendly talk' to a mothers' meeting, but even this is no simple matter if it is to be given well, for simplicity and conciseness are rarely combined with a limited capacity." It is incumbent upon all sanitary inspectors to see to it that the possibilities of their profession do not fail of realization because of 20 BELL—SANITARY INSPECTOR OF THE COMMUNITY. Vol. XVII. their neglect to inform themselves of the advances made in sanita tion.. They must always do the best they can. Well enough is not sufficient. A mere show of enthusiasm and energy will not satisfy. To have no deeper interest, no higher ambition, than the accomplish ment of that which suffices to save him from censure by his superiors, exhibits an attitude of mind toward his profession which is bound to be barren of anything worth while and which in the long run will make his work a dull occupation. It is a safeguard to his own per sonal contentment and essential to his success that he thoroughly acquaint himself with both the theoretical and practical sides of his job and discern all the possibilities in his field of work. Probably the large majority of those men and women who are serving as sanitary inspectors in this country to-day have not had a practical course in sanitary science, but that handicap is not, and need not be, a serious impediment to success, nor should it have any other effect than to inspire a determination to learn by reading, ob servation, and otherwise, anything and everything that bears upon the profession. All those thus situated are in the same position as doctors and lawyers who, in the early days when there were few if any schools and many students, simply read medicine or law under the direction of a preceptor. At a certain period of the world's progress some of these men of the old order, so to speak, had, of course, to measure themselves with the product of scientific schools, and they did it creditably by just the process that is open to the sani tary inspector of the old order, or what is hoped will soon become an ohi order. In other words, it is the urgent duty of the sanitary inspector of this class to readjust his ideas to the fast-coming new order of things, and to place his services on the substantial basis of scientific knowledge. The need that all persons occupying the posi tion of sanitary inspector shall, by every available means and an un flagging acquisitiveness, improve their fitness for office is, of course, imperative ; but, on the reasoning that the process of rusting is more reprehensible than the failure to develop, the obligation to keep in touch with progress which rests upon those who are happy pos sessors of scientific training as a background, is as vital as self- preservation. As intimated above, in the last analysis the tell-tale of the efficiency of the sanitary inspector is the health of his district. By this I wish to be understood as referring to the relation of his work to that of the doctor. The sanitary officer precedes in the field, and it is only where his failures crop out in relation to preventable diseases that the doctor steps into the breach. The sanitary inspector should be and is coming to be, more and more, a valuable accessory for the dissemination of sanitary gospel and, in addition, he stands ready Xo. 1. 21 BUNKER ACID-BASE EQUILIBRIUM. to ameliorate the situation where preventive efforts have failed, but the sanitary inspector must square himself with his conscience and with the public and with his chief that he has honestly and faithfully done everything that was humanly possible in the circum stances to prevent the demand for the doctor's healing assistance. ACID-BASE EaiJILIBRITJM. By C. W. O. Bunkeu, Lieutenant Commander, Medical Corps, United States Navy. Fourteen years ago Ewing reviewed the question of acidosis. Since that time our conceptions have undergone profound modifications, and Haldane, Haggard, Henderson, and Van Slyke have figured prominently in this development. I have drawn largely upon their writings for this article. At that time acidosis meant conditions showing increased amounts of acetone bodies in the blood (ketosis) or in the urine (ketonuria), usually accompanied by increased ex cretion of ammonia. We now, however, recognize the deeper sig nificance of this ketosis, i. e., that the body is robbed of its bases, and extend the term acidosis to include conditions in which other factors produce such a result. Moreover, we now realize that acidosis is but a particular phase of disturbance of the acid-base equilibrium of the body. Van Slyke restricts acidosis to a condition caused by acid retention sufficient to lower either the bicarbonate or the pH of the blood below normal limits. Work of the past five years has demonstrated the necessity for a broader vision, and we must conceive nine clinical phases of acid-base equilibrium, determined by high, low, or normal bicar bonate in the presence of a high, low, or normal pH. The pH of the blood may be considered the danger signal—as long as it is normal the acid-base equilibrium is normal or compensated ; otherwise, it is uncompensated and life is seriously threatened. The normal pH of the blood may be given as 7.3 to 7.5, each individual, however, having narrower limits. That of blood serum is about 0.2 higher, and that of the other body fluids (not the excretions) prob ably closely approximates and promptly follows any change in that of the blood plasma. Variations to the acid side may, for a short time at least, be as low as 7, although not much lower without fatal results; 7 is considered as the point where coma occurs. Variations to the alkaline side {alkalosis) beyond 7.8 are accompanied by symp toms of tetany, although one is not at present justified in assuming that all tetany is either caused or accompanied by alkalosis. So the extreme range of reaction compatible with life probably lies ap proximately between pH of 7 and 7.8. 22 Vol. XVII. BUNKER ACID-BASE EQUILIBRIUM. The hydrogen-ion concentration (or its derivative, pH) of the blood varies as the ratio between the concentrations of dissolved carbonic acid and bicarbonate (generally indicated by rfflJQQ 1 in which B represents the metal, such as Na, K, etc., in the bicarbon ate), i. e., a relative increase in the H2C03 increases the hydrogen-ion o o o ▼ n t* — *03%sinmoA concentration (CH+) and lowers the pH, and vice versa. A full ap preciation of the significance of this ratio is the basis of an intelli gent comprehension of acid-base equilibrium. The accompanying chart (modified from Peters, Barr, and Rule, and Van Slyke) is a graphic representation of essential facts in acid No. 1. 23 BUNKER—ACID-BASE EQUILIBRIUM. base equilibrium. Ordinates represent total C02 (content, which com prises that in simple solution and that as bicarbonate) of whole blood in volumes per cent, and abscissae the millimeters C02 tension in the blood as withdrawn. The line OT gives the proportion of total C02 present in simple solution. pH values are shown by the lines OL, OM. etc. The extreme normals for carbon-dioxide-absorption curves are OP and OE. These curves are obtained by plotting the total C02 of whole blood after being drawn and equilibrated with dif ferent percentages (tensions) of C02. The intersection of such a tune with total C02 value of the blood as drawn would give the C02 tension in the blood and also the pH. The actual state of the acid-base balance can only be determined by the use of any two of a number of interdependent variables, such as total C02, C02 tension, pH, H2C03 concentration, other buffers than bicarbonate, plasma chloride, ratio of oxyhemoglobin to hemoglobin, etc. Findings that fall within -ABCD and at about 40 millimeters tension indicate a normal equilibrium for the resting individual at ordinary altitudes ; or, such a normal would be a total C02 of about 49 (43-56) volumes per cent for whole blood, and 50-65 volumes per cent for plasma. The normal for the individual falls within nar rower limits. The C02 tension of alveolar air may be the same or vary as much as 20 millimeters below, while that of venous blood will be about 6 (0.8-10) millimeters higher than that of arterial blood. So, although the C02 tension in alveolar air is usually approximately that in arterial blood, it is not an accurate measure of the latter, being dependent upon the extent to which pathological processes may influence ventilation of alveoli or alter their walls so as to impair diffusion, etc. The "C02 capacity (combining power)" of plasma may be as much as 15 volumes per cent more than the total C02 of whole blood. The ratio, , is influenced by many factors, of which the following is an analysis. To increase or protect bicarbonate : 1. Administration of same. 2. Loss of gastric HC1 caused by obstructing the pylorus, and regularly washing out the stomach for some days. 3. Processes indicated by increased excretion via the urine of ammonia (probably diverted from urea formation) and titrable acid (including buffer acids, such as acid phos phates) . 4.

Ketosis may also occur in fever, malignancy, psychoses, and le sions of the central nervous system, delayed chloroform poisoning, liyperemesis gravidarum, inanition, cachexia, starvation, etc. Tiie symptomatology of disturbances of the acid-base equilibrium is well known. Alkalosis accompanied by tetany may be expected to present the symptoms of the latter, including carpopedal spasm, Chvostek's sign, Erb's sign. Trousseau's sign, etc. The classic evi 30 Vol. XVII BUXKEH ACID-BASE EQUILIBRIUM. dence of acidosis is Kusselmaul's air hunger—a respiratory disturb ance manifesting hyperpnoeic dyspnoea without cyanosis, perhaps even with an abnormally bright color of the mucous membranes. This hyperpncea is the best of all the signs of acidosis to be obtained by physical examination alone. Such symptoms, however, occur only with the severer degrees of disturbance of the acid-base equilibrium, and earlier evidence must be sought in the blood and secretions by laboratory procedures if timely intervention is to be secured. Van Slyke's resume above relative to different areas of the chart indi cates some points in diagnosis. Dyspnoea on exertion may precede the true hyperpncea. Van Slyke also calls attention to the fact that two variables are necessary for an exact estimate of the status of acid-base equilib rium, as noted above. But he furthermore states that the conditions (diabetes mellitus, nephritis, metabolic disturbances of infants, and most other pathological as well as normal conditions) most com monly examined in this respect usually present a normal pH, and, when only one determination is made, either the carbon-dioxide ten sion or the carbon-dioxide combining power of whole blood (pref erably) or plasma will suffice. With an abnormal pH, however, de termination of only one variable will be inadequate to accurately define the condition. Clinical methods comprise tests for whole blood or plasma C02 or bicarbonate, alveolar CO, tension, bicarbonate (soda) tolerance, pH of blood or urine, Sellard's test, NH3 quotient of urine, or presence of abnormal acids (particularly acetone bodies) in blood or urine. The first two methods are the ones of choice, particularly the first, as by it one can estimate the reserve of the very important blood buf fer, bicarbonate, and its result closely indicates the total buffers. Free H2C03 is present in the body fluids in such concentration that it automatically converts into bicarbonate all bases not bound by other acids. The bicarbonate, therefore, represents the excess of base which is left after all the nonvolatile acids have been neutralized, and it is available for the immediate neutralization of further acids. In this sense, it constitutes the alkali reserve of the body. The en trance of free acids reduces bicarbonate "to an extent proportionate to their amount. The determination of plasma bicarbonate (C02 capacity, or C02 combining power) by either the gas or titration method of Van Slyke is not difficult. It may be considered the standard method, and the cooperation of the patient is not needed. Normal values for men were given as 77 to 53 volume per cent; 53 to 40 means mild acidosis without symptoms; 40 to 30, a moderate to severe acidosis, possibly with symptoms; less than 30, severe with symptoms; 20 is osually fatal. Xo. 1. 31 BUXKER—ACID-BASE EQUILJBKIUM. The alveolar C02 tension is a practical measure of the blood bicar bonate, but the cooperation of the patient is desirable. The sample of expired air obtained at the end of a full expiration after a normal inspiration should approximate the C02 tension in the arterial blood, although, as already noted, it may be on occasion as much as 20 millimeters lower. One obtained by rebreathing is closer to that of venous blood. Results are affected by manjT conditions, e. g., pathological processes, especially pulmonary and advanced cardiac disease, drugs, emotion, atmospheric conditions, position of the body, digestion, etc. The tensions in infants is 3 to 5 millimeters lower than in adults. For the latter, 40 to 45 millimeters is normal, 30 to 35 in dicative of mild acidosis, 20 millimeters means imminent danger, and 8 to 10 may be observed in coma. The tolerance for bicarbonate is a very convenient and practical measure of acidosis, and means the dose of sodium bicarbonate re quired to produce a urine alkaline or amphoteric to litmus. A normal finding is 5 to 10 grams ; 20 is required with a mild ; 30 to 40 with a more severe ; and more than 40 grams with extreme degrees of acidosis. In coma, it is usually impossible to produce an alkaline urine. Kidney function does not interfere with bicarbonate excre tion, and tolerance is the result of a need for fixed bases. Determination of the pH is clinically unsatisfactory, especially in the urine where it is particularly unreliable. In the blood, the change is small and late, and results lack uniformity by reason of the technic. Titration does not measure hydrion, and is unsatis factory as the proteins interfere with a clear end point. Certain changes in the urine are recognized and acceptable as indi rect evidence of acidosis, but they are not synonymous and are de pendent upon renal integrity and other factors for constancy. These comprise acetone bodies, NH3 quotient, and titrable acidity. The last is of no real service clinically, and it must be borne in mind that acetone bodies are not necessarily present in, nor is the NHS quotient necessarily affected by, acidosis. The changes neither parallel the severity of acidosis, nor measure the efficiency of compensatory processes. They have diagnostic value, but are not safe clinical guides otherwise. tennined and upon a mixed diet, is normally about 5 per cent. Values of 10 to 40 per cent occur in acidosis. It may be increased by diet, disturbances of protein metabolism, ammoniacal fermentation, etc., and there may be no increase in certain diseases with acidosis. It is said that the NH, parallels the acetone bodies, and is a better measure of ketosis. The ammonia of urine, as usually de- 32 BUNKER ACID-BASE EQUILIBRIUM. Vol. XVII Acetone and diacetic acid have the same clinical significance: a progressive increase gives a grave prognosis, and it is generally con sidered that the presence of (3-hydroxybutyric acid indicates greater severity. It is well to bear in mind that the sodium nitroprusside tests for acetone are really delicate tests for diacetic acid. But as these substances have the same significance, it is wasted effort to attempt to clinically differentiate them. It is said that the kidneys do not excrete acetone but do diacetic acid, the latter changing into the former in the urine, which, when freshly passed, contains about 10 times as much diacetic acid as acetone. More acetone forms as the urine stands. The qualitative test for acetone bodies in the breath is sensitive, and yields positive results earlier than Gerhardt's test on urine. Moreover, it is useful when impaired kidney function pre vents excretion of acetone bodies via the kidneys. One might men tion in passing that the sweetish odor in such a breath is not due to acetone, but to some associated unidentified substance. Intelligent treatment demands a recognition of the etiological factors involved. With acidosis, is it acapnial or acidotic in origin '( In general, the former calls for administration of CO„. and the latter for bicarbonate ; the use of the wrong one is dangerous. The former is employed as a 6 to 10 per cent mixture in oxygen. Mar riott and Haessler call attention to a point that may have therapeutic bearing. With phosphate retention, the calcium in serum may be decreased to 1.5 mg. per 100 mils. Administration of phosphate causes an increased elimination of calcium via the feces, and the converse is also true. Bicarbonate (sodium bicarbonate) seems especially efficacious in conditions associated with phosphate reten tion. It is now about a decade since Sellards obtained his brilliant results in the acute nephritis of cholera, and since Fischer advised alkalinization in similar conditions. Bicarbonate is less effective in the presence of ketosis. Glucose is indicated in conditions with ketosis due to carbohydrate deficiency, providing the organism can assimilate it. The administration of bicarbonate is best controlled by estimations of the plasma C02 capacity; 0.5 gram NaHCO., per 19 kilograms body weight will raise it 1 volume per cent. Palmer, Salvesen, and Jackson recommend its oral administration (nausea is a contra indication) in 100 mils of water every 30 minutes, using 2, 5, and 10 grams as the dose in cases showing plasma C02 capacities of over 50, 40 to 50, and less than 40 vplume per cent, respectively. For more severe acidosis they advise administration every hour. The effect is determined by blood examinations, the frequency of which they lessen by following the pH of the urine colorimetrically before each dose. An increase of 0.3 to 0.4 in the pH calls for a determination of plasma bicarbonate. The more usual procedure, however, is to No. 1. 33 BUNKER ACID-BASE EQUILIBRIUM. stop the bicarbonate when the urine is alkaline or amphoteric to litmus. Methyl red is a better indicator for the urine than litmus in that, by ceasing administration when the urine produces a yellow color with methyl red, one lessens the danger of overdosage. Relative to the administration of bicarbonate in treatment, there is now a decided reaction against the use of injudicious amounts, by reason of the danger of alkalosis. There is a tendency to employ it only in decompensated acidosis, and certainly to control it by estimations of the plasma C02 capacity. It is distinctly contra- indicated in conditions with a low plasma C02 capacity due to acapnial processes. L. J. Henderson states that any attempt to treat a disease like nephritis by the indiscriminate administration of large amounts of alkali is malpractice. Small amounts over a long period are justifiable and make acidosis impossible. In most pathological cases, the urine does not become more alkaline than the blood until the plasma bicarbonate is above normal. Therefore, reliance upon a urine alkaline to litmus may involve the use of unnecessary and possibly injurious amounts of bicarbonate, and erroneous deductions as regards the severity of the acidosis. In surgery, as noted above, evidence of even slight acidosis should be corrected prior to operation by the administration of bicarbonate. Frank states that the patient is not in the best possible condition to undergo any surgical procedure when he has a blood pH of below 7.35, an alveolar C02 tension below 35 millimeters, or a soda tolerance test above 15 grams. One should add a plasma bicarbonate under 53 volume per cent C02. Women and children should be especially considered in view of their normally low alkali reserve. For the very depressed condition following prolonged etherization, Haggard and Henderson recommend the use of the C02 mixture noted above, as it induces hyperpnoea, helps remove the anesthetic, and restores the plasma C02 and bicarbonate. Alkali is of only minor value in the acidosis of diabetes mellitus Its effect is temporary, being often lost in a few hours, and heroic injections are often required. It is of definite value only in long and stubborn acidosis, or to combat coma in certain severe cases. Twenty-five grams in 5 per cent solution may be used intravenously for impending coma. Death is not necessarily caused by the reac tion of the blood, for alkalinization may keep it normal, but the patient may die in coma with typical ketosis. The ketosis is better controlled by other methods, especially periods of fasting alternating with periods of properly adjusted diet, combined with rest and warmth. Fasting is more apt to be followed by acidosis in a normal person than in a diabetic. The ketosis is not necessarily due to lack of carbohydrates, but, perhaps, they do the most to control it by insuring proper oxidation of fats, and the rates of protein 34 NEUBERGER —AVIATION MEDICINE IN TJ. S. NAVY. Vol. XVH. and fat metabolism must be lowered to meet that of carbohydrate. It must not be forgotten that proteins yield 48 to 80 per cent glucose in metabolism, depending upon the variety. As with all methods of treatment, acidosis is more to be feared than hyperglycemia, but especially with the Allen method. The plasma bicarbonate should be closely followed, and, with the Allen treatment, a certain drop is permissible before interruption of the fast. With an initial plasma C02 capacity of 77 to 53 volume per cent CO., a drop to 45 is allow able : with 53 to 40, a further drop of 5 to 10 volume per cent ; with 40 to 31, a drop of 2 to 3; with less than 31, interrupt the fast in 6 to 12 hours unless the value rises by reason of the fast and alka linization. Alkali is of real value in nephritis, especially in acute types. Even in the chronic or in the uremic cases, it affords at least much symp tomatic relief. Sellards separates the frankly parenchymatous types as having a very low bicarbonate tolerance, small doses often pro ducing an alkaline urine ; and one should be careful in any attempts at alkalinization in such cases, as they may react violently. With the other types, the effect of a course of bicarbonate lasts for a com paratively long time, a normal response occurring after possibly even weesk. Acidosis itself is not infrequently the immediate cause of death in the nephropathies. As regards infants and children, restortaion of bases may produce a normal blood bicarbonate and alleviate hyperpncea, but the child dies nevertheless. Alkali gives good results with older children, but an acidosis once established in infants may result in death despite it. It is, therefore, desirable to begin alkalinization even before acidosis is demonstrable. Rapid action should be sought, and any method may be used, although a 4 per cent solution intravenously is considered preferable ; the alkali is administered until the usual urine reaction is obtained, and even 10 grams per 24 hours has been given to an infant aged less than one year. With ketosis, no glycuresis, and a normal blood sugar, give glucose. One should also administer much water. AVIATION MEDICINE IN THE UNITED STATES NAVY. By J. F. N'euberger, Lieutenant, Medical Corps, United States Nary. HYGIENE OF THE AVIATOR. As has been repeatedly stated, aviation medicine has as a primary function the task of keeping the flier physically and mentally fit. When the United States entered the war medical officers had had little opportunity to study the effects of continuous flying on the airman. It was soon realized that the ordinary standards of fitness Xo. 1. NEUBERGER —AVIATION MEDICINE IN U. S. NAVY. 35 for the regular officers of the line and staff of the Army and Navy were not applicable to the aviator. The first aim of the leaders in aviation medicine was to determine standards of fitness required in air work and to find an explanation for the physical and mental deterioration observed among aviators. The Army early recognized the necessity of keeping their fliers in the pink of condition and physical directors were provided for the various training fields of the air service. These physical direc tors cooperated with the flight surgeons not only in keeping the men in the best condition possible, but also in teaching them how to in crease their natural strength and endurance, to sharpen their powers of alertness and to obtain quick, cool action, and muscular and mental coordination. These physical directors did wonderful work during the war and were in no small way responsible for the excellent work of the air service in the armies of the Allies. In the Army's publication, Aviation Medicine in the A. E. F., it is stated that experience has shown that in sports, in which the sub ject is undergoing great physical and nervous strain, the period of efficiency is limited. It is impossible to fix the exact duration of this period. It depends upon the physical endowment of the subject and the care he gives his body. However, each athlete has his day, some lasting only a short period, some for months or even years. The strain in aviation, especially in war times, demands more of the human mechanism than any other sport. It also follows, therefrom, that the period of efficiency is limited. The exact duration of this period will depend upon the effort demanded from the subject, the condition under which flights are made, and above all, upon the mode of life of the aviator. The necessity for health comes from the fact that the aviator has need of all his physical energy and intelligence. Flying is a question of an active- well-balanced, decisive mind, and of quick reflex actions. Not a thing can be left to chance. Every flier must quickly recognize the slightest difficulty with his machine. His senses must give him accurate information of changes in the rhythm of his motor, of the sing of the air across the wires of his machine, and of his position in space. He must be master of his impressions and be ready to make prompt decisions in a calm, cool manner. His correcting movements should be made with precision and without exaggeration. It is clearly recognized that the aviator's reaction to stimuli are disturbed by disease, worry, fatigue or after excesses. A delay of a second or a part of a second in correcting an error in the air or in landing mean all the difference between a crash and safety. Excellent physical condition permits the body to react with more adequate compensation to altitude and cold. Hygienic living is necessary to keep the body and mind in good condition. 36 NEUBERGER AVIATION MEDICINE IN U. S. NAVY. Vol. XVII Sleep is most important. Firm-nerved men become vacillating and irritable on account of lack of sleep, and are quick to take offense. Troubles that would be laughed away by rested men are magnified by sluggish brains. Eight hours of sleep is a good average. A few men seem to be able to do efficient work with seven hours or less. Edison is one of these. It is said Napoleon was another. But it is known that Napoleon in his later years showed a loss of energy due to accumulated fatigue, as he often dropped asleep in the midst of important matters. To get the sleep one needs, often takes courage, the courage to refuse the invitations of pleasure. It is believed that lack of sleep is responsible for many minor illnesses, because it lowers the vitality or resistance of the body, thereby increasing its susceptibility to infection. Alcohol. —The alcohol problem, despite prohibition and many opinions to the contrary, is still a grave one. The consequences of drinking are too well known to every one to even be discussed, except to show that too much indulgence in alcohol has been the cause of the loss of many a good flier to the service. It is often claimed, however, by aviators that a man can fly better when slightly under the influence of alcohol. The writer's experience, however, does not confirm the above statement. Excessive alcohol will remove the sense of fear so that the flier becomes reckless and careless and does not use his best judgment in case of difficulty. Major Dunlap at the research laboratory, Mineola, has shown by experience that alcohol produces the same effect as high altitude or low oxygen. It is very easy for a pilot to lower his physical condition to the point of useless- ness by the constant use of alcohol. He may be able to fly, but he is not flying at his best. Clouded brains prove dangerous and are not fit to direct an air or sea plane. Smoking.— Smoking when carried on to such an extent as to cause nervousness, palpitation of the heart, faintness. or impair ment of vision must be curtailed. Most aviators smoke too much, and in talking to them about it they will all admit it. yet they keep on smoking. Excessive smoking makes the flier turn out of bed heavy of head and this in turn, together with lowered vitality, causes loss of enthusiasm in his work and has a tendency to break down his morale. Underwood and Reeves, in writing on " The ef fects of smoking on the visual acuity," state that one of the great est difficulities encountered in their work was that most of the workers are habitual smokers and^are never free from any such effects as smoking may have. This makes a control test, in the strict sense of the word, almost impossible. Such clinical disturb ances, both in vision and of other bodily functions, as have been ascribed by medical men to the use of tobacco have been held to be the result of long-continued use. Apart from the graver func No. I. NECBERGER —-AVIATION MEDICINE IN TJ. S. NAVY. 37 tional and anatomical disturbances there is a possibility that func tional depression, short of anything that might be held to threaten permanent disability, could result from continued smoking and be come fatal to the flier by reason of the exacting requirements of his work. Drugs. —Many fliers come to the hospital and ask for aspirin. It gives the medical officer a clue to the fact that the flier is not feeling well. Drugs do not render one fit, but only temporarily hide the symptoms of fatigue and illness. When the flier comes to the sick bay and asks for medicine, the medical officer has to handle him with a great deal of tact. If the medical officer uses his au thority and immediately places the flier on the sick list, the aviators will not report to the sick bay. being afraid that the medical officer will not allow them to fly. I have always made it a point to enter into a personal conversation with the flier and talk his case over with him and specifically ask him whether he thinks himself capable under his present condition to fly as well as he does on other days when he feels normal. He, usually, answers " No." By talking it over with him in this manner, he feels that one is only doing what is best for him and he himself usually suggests a relief from flying. Overeating. —It is a known fact that work in the air produces a very keen appetite and there is a great tendency to overeat. Over eating produces a sense of fullness and general sluggishness, con ditions which are not desirable in flying. The effects of overeating are particularly manifect after lunch, as a great deal of flying is carried on in the afternoon. The midday meal or lunch should con sist of a very light repast, sufficient, however, to supply the desired amount of energy. Eating between meals, as well as the constant or frequent eating of confectionery is not advisable. Physical exercises. —In the Army's publication. Aviation Medicine in the A. E. F., it is stated that physical exercise, judiciously em ployed will do much to secure physical fitness and serves to arrest the onset of staleness ; it will also put the body in condition to sus tain the compensations needed when flying at high altitudes. A man in good physical condition is much more resistant to altitude sickness than the physically " soft " man. The ability to endure high alti tudes is dependent upon adaptive changes in respiration, circulation, and the blood itself. The untrained individual breathes more fre quently and shallowly than the trained man whose breathing is low and deep. Shallow breathing does not ventilate the lungs effectively. The habit of deep breathing can be cultivated by ex ercise, but not so satisfactorily by voluntary effort. It is also known that at high altitudes, physical exertion makes a greater demand upon the heart than the same amount of work does at sea level. 38 NEUBEKGER AVIATION MEDICINE IN U. S. NAVY. Vol. XVII. Men in good physical condition can stand the strain on the heart better than individuals weakened by dissipation and fatigue. Con sistent physical work increases the percentage of hemoglobin in the blood. Capt. William L. Culpepper, United States Army, has shown that the hemoglobin and the red blood cells are temporarily increased in the aviator during flight, which is very advantageous at high altitudes. Exercises must necessarily be arranged according to the tempera ture and the weather. Mass athletics are very much desired, as foot ball, soccer, baseball, pushball, and basketball. Tennis, handball, and calisthenics are beneficial. General hygienic principles. —The general h\7giene of the airman scarcely differs from that of other sportsmen. As in the case of all other forms of exercise, the younger he is the better he will be able to adapt himself to it. Training in flying after the age of 32 is not recommended, although some men above this age have developed into good flyers. Airmen need regular intervals of rest. Some writers recommend three weeks' rest after four months' flying. It is believed a better method would be to give a rest after so many hours of continuous flying. At most air stations it is necessary for the pilots to stand officer of the day's duty. This necessitates making frequent inspec tions at night and being subject to call at all hours, and oftentimes the flier does not obtain the necessary amount of sleep. I can not too strongly recommend that any flying officer standing officer of the day's duty should be excused not only from flying but from all other duties the day following, in order to enable him to make up for the loss of sleep, thereby regaining his energy and putting him back to his nor mal physical condition. The writer knows of several instances in which crashes followed such a tour of duty and could only attribute them to a lack of the proper amount of sleep. The commanding officers of air stations should be made to realize the above facts. After all, for the flier, the danger is personal. His life is in his own hands. It is he who pays the penalty, irrespective of where the re sponsibility lies. Another point of importance in connection with the hygiene of the aviator is the attention to the needs of nature. It is desirable to move one's bowels and void urine before going up in an airplane in order to avoid, in case of fall, the rupture which may result from a loaded intestine or bladder. The cold of high altitudes leads to an increased formation of urine, and this causes distress unless relieved. Certain appliances for aviators have been designed with this point in view, which will be described in a later article. Clothing worn while flying should not fit too tightly. Clothing next to the skin should be made of wool, as this material counteracts No. 1. 39 BELLI—PERSONAL HYGIENE OF AVIATORS. most advantageously the loss of heat. A combination suit, fur lined, and fur-lined gloves and boots are very satisfactory as an outer cov ering. Frostbites, parching, and chapping of the skin, cracking of the lips, and dryness of the nose are often the result of flying in high alti tudes. These conditions can be prevented by applying an ointment of petrolatum. REFERENCES. Aviation Medicine in A. E. F. War Department, Document No. 1004, Office of the Adjutant General. Underwood, H.

Bnxi, Colonel, Medical Corps, Royal Italian Navy; Director Psycho physiological Division of Aviation, Royal School of Naval Military Hygiene, " A. Pas- qnale," of Naples. [Translated and condensed by Capt. J. S. Taylor, Medical Corps, United States Navy.] Aviation is comparable to no other form of endeavor and only partially resembles mountain climbing. The human organism is unlike that of birds and is not designed by nature for flight. Eagles and vultures have been observed at altitudes of 7,000 meters. Cigna, over a century ago, reported a swallow that resisted for more than half an hour a pressure of 229 milimeters, which is greater than would be endured at the summit of Mount Everest —a height of S.840 meters. The high development of the semicircular canals in birds ; and the air spaces in their bones and feathers, are features which enable them to confront the chemico-physical conditions of flight. Man's state is abnormal from the moment he leaves the ground until his return. There is diminished oxygen and low temperature at high altitudes, and the aviator experiences a change from stable to unstable equi librium as soon as he leaves the ground. He is aided by certain com pensatory actions on the part of the respiratory and circulatory organs. The respiratory rate is reduced; breathing is deeper and intermittent. There is an increase of blood pressure and the cardiac systole becomes more frequent. In no other form of human effort is the personal equation so strik ing as in aviation. The weak, cachectic, abnormal, those in a state of exhaustion can not support the variations of external physical agents encountered and must be prevented from flying. But even individuals who are sound in a psychic and physical sense show 40 BELLI PERSONAL HYGIENE OF AVIATORS. Vol. XVII. differences of reaction during flight : There are all shades of dif ference between the bird man and the one who can not rise a few meters above the earth without experiencing all the torments of hell. Psychophysiological examination usually helps to exclude those less fitted for aviation and liable to fatal accidents, but does not posi tively determine the individual reaction. A man's behavior under atmospheric rarefaction is only forecast by the pneumatic chamber. Somewhat as we judge our Alpine troops, the Americans attempt to classify aviators by the altitudes they can safely negotiate. 1. Those who can go to the highest altitudes. 2. Those who should not ascend above 5,000 meters. 3. Those who should not ascend above 2,500 meters. Intolerance of aerial flight presents itself in two distinct forms. One resembles the picture of the disturbances common to going to sea and develops at low levels —malaise, vertigo, nausea, and vomit ing. The second form, called altitude sickness, or aviator's sickness, appears at high altitudes, and the phenomena are serious and com plicated—headache, vertigo, cyanosis, roaring in the ears, impair ment of vision, respiratory distress, cardiac palpitation, syncope, somnolence, and sleep. The most pronounced symptoms concern the nervous system. The muscle sense is obtunded : muscular contractions are feeble and the psychic control of muscular movements is impaired. Visual acuity is reduced: likewise the peripheral field of vision. The shape and distance of objects is imperfectly perceived. Con centration of attention is reduced ; the will is enfeebled and absolute intellectual inertia develops. This impairment of the psychic powers acquires special significance from the fact that the subjects thereof give no warning of the change from a physiological to a pathological condition and go forth entirely unconscious of it to meet the dangers that threaten. The type of symptoms varies with the individual. Altitude sickness and mountain sickness differ in that the latter appears at lower altitudes, owing to increased oxygen requirements following muscular exertion. The sense of equilibrium, as in the case of sea goers, readily adapts itself after a few flights to the new positions of the body with reference to the outside world and disturbances of equilibrium grad ually cease to develop. But on the contrary man does not possess the power to become accustomed to altitude sickness in the sense of recognizing the symptoms, though there is some increase of toler ation for them. The statistics of the World War show that out of 100 milder casualties in the air, 2 were due to circumstances of battle, 8 to de fects of apparatus and motors. 90 to causes inherent in man. This Xo. 1. 41 BELLI PERSONAL HYGIENE OF AVIATORS. proves that the most important factor in successful flight is a per sonnel not only trained technically but, above all, physically adapted thereto. Flight must be restricted as far as possible to men physically perfect and endowed with the best psychic and physical qualities. Every government requires a severe test for the personnel of avia tion. The Italian Navy conducts its examinations through the psychophysiological bureau attached to the Royal Naval Medical School, Naples. Aviation, like athletics, involves great expenditure of nervous energy and, as in the case of sports, the capacity therefor is limited. Aviators after a continuous service of months or years show signs of incapacity and must temporarily or permanently be excused from further flight. The incapacity shows in a technical way by less able handling of the machine, especially in landings. In a medical way the incapacity is evidenced by tremor of the hands and eyelids, • insomnia, deficient muscular control, increased reflexes and psychic irritability. Nervous exhaustion is a not unusual cause of casualties, many of which may be ascribed to the fact that through false pride the exhausted ones have insisted in continuing a flight and paid dearly for their imprudence. Guynemer in his later period was nervous and irritable, in spite of which and despite advice to the contrary, he insisted on starting on that, last flight. The individual's constitution and his habits of life determine full capacity for flight. Incapacity' results from loss of sleep, excessive fatigue, sickness, and abovfl'till from nervous exhaustion following excesses. Such excesses —smoking, gambling, drink, and sexual in dulgence^—flow in part from a certain fatalism imposed by the . aviator's very calling. The authorities are not in a position to regu late the minor details of an individual aviator's private life. Hence the necessity that all concerned should appreciate the scientific basis for rules of health bearing on flight and the importance of a maxi mum of efficiency and a maximum of service. For successful flight, apparatus and motors must be in good order ; on his side the aviator must have a maximum of physical and moral energy. The human machine is fully as complicated and requires just as minute care as the airplane. HYGIENIC RULES. The function of preventive medicine is not fully accomplished by the mere selection of the fit and the elimination of the unfit ; but it must include preservation of forces. The cardinal rule is : Modera tion in all things. 42 BELLI —PERSONAL HYGIENE OF AVIATORS. Vol. XVII. FOOD. Food is important both as to quality and quantity. Abnormal digestion and constipation weaken both the physical and mental powers and predispose to altitude sickness. Flight sharpens the appetite and predisposes the aviator to eat heavily which is in jurious. The hours for meals are matters of importance. One should not eat heavily just prior to flight. (Less blood to brain; more to stom ach, predisposition to vomiting, nausea, etc.) The morning meal should be light and taken about noon, after the morning exercises. These exercises should not be resumed before 4 p. m. The principal meal of the day is best taken at night, when the work of the day is over. During flight, hot drinks from a thermos bottle (e. g., chocolate) and sweets are best. Between flights a sandwich, coffee, or a light ' broth containing a farinaceous ingredient (noodles, etc.) are bene ficial. REST AND SLEEP. Flights should not be too prolonged and should alternate with suitable periods of rest. When the aviator returns to camp, showing unusual fatigue, the rest period must be correspondingly prolonged, eight hours being the minimum period of sleep to restore him. CLOTHING. --• Clothing must be warm to protect against the cold of high alti tudes which favors discomfort and aggravates symptoms due to high altitude. But garments must not constrict the body. Under garments next to the skin should be woolen ; outer garments should be fur lined throughout. Fur-lined gloves for the hands and linen shoes lined with fur for feet add to the aviator's comfort. PERSONAL CLEANLINESS. Personal cleanliness is of special importance in the event of in jury so as to lessen chances of infection. A tepid shower or tepid bath is favored ; warm baths if prolonged and oft repeated are de pressing to the nervous system. EXERCISE. Physical exercise of a kind agreeable to the individual and not entailing unusual expenditure of nervous and physical energy is highly desirable. Stunts, athletic meets, and the like are objection able. Mountain climbing, sailing, swimming, and polo are the best pastimes. JfeL BELLI PERSONAL HYGIENE OF AVIATORS. 43 In the United States the training of aviators includes physical drills calculated to promote muscular coordination rather than mus cular strength, 'and to develop visual, acoustic, and static control. VISION. Perfect vision is as important to the aviator as to the mountain climber. Aviation involves ocular strain and in bright weather the ucess of solar rays dazzles the eyes and reduces vision. The high velocity of flight causes a current of air which tends to dry the con junctiva and cornea and all minute foreign bodies impinge on the eye with force and favor trauma and infection. The wearing of goggles is imperative. Usually, aviators dislike wearing them. Still the benefits of goggles largely compensate for some reduction of the field of vision and acuity of vision. Mica lenses have been recommended, through dread of possible injuries if crystal lenses should be broken. Mica is far less trans parent than glass and the danger of injury to the globe from broken eyeglasses is much exaggerated. Wilmer and Berens, during two years on the American front in France, saw only one case of eye injury due to broken glasses, but it was accompanied by general lesions serious enough to cause the death of the victim on the day following. The best goggles are made of crystals having at least 2 millimeters of thickness. The surfaces are plain and parallel. A pure white glass capable of transmitting 90 to 100 per cent of incident rays is commonly used, but it is better to use glasses with a slight yellow- 2reen tint to absorb short-wave actinic rays. These do not affect color perception and are a comfort in traversing snow fields, large bodies of water, and cloud strata. The lenses should be round or slightly ovoid, set in a metal frame, and retained by metal rods. They must be easily removable during flight, and the aviator should have spare lenses. The spectacles must be strongly made and easily taken off, with one hand only. All metal parts must be sheathed in leather or cloth to avoid frostbite. In order to protect the eye from frostbites the goggles must close hermetically over the orbits, even at the sides. This results in con densation of moisture and when temperature is below freezing a fine frost collects on the glasses which interferes seriously with vision. In some models the full protection is obtained by metal gauze at the sides to favor the escape of water vapor. It must be admitted that, to date, all types leave much to be desired from this point of view. 108390—22 4 44 BELLI —PERSONAL HYGIENE OF AVIATORS. Vol. XVII. THE EAR. Hearing and equilibrium are of the greatest importance in flight. The aviator must be able to determine by its rhythm the regularity of operation and the number of turns of his propeller. Also he must be able to estimate his position relative to the medium in which he is immersed. The care of the ear is therefore of immense importance. Accumu lations of wax must be prevented, since they interfere with vibrations of the tympanum. Further, there must be a balance between the outside air and the contents of the tympanum to prevent vertigo, subjective sounds, and pain, occurring when communication is inter rupted. The closure of the Eustachian tube becomes specially serious in connection with the rapid and powerful disturbance of balance between the inside and outside air as in hurried landings from high altitudes. Gradenigo, the high authority serving as consultant to the psychophysiological bureau at Naples, insists on full and constant patency of the Eustachian tube. He advises frequent acts of degluti tion during recompression, and even the Valsalva method of deep •expiration with mouth and nostrils closed. RESPIRATION. While respiration is automatic, still, within limits, it can be modi- tied by the will. This is not recommended. Aviators should be required to breathe through the nose, with the mouth closed, in order to moisten, warm, and filter the inspired air and reduce the pressure of the strong air current due to the velocity of the machine. This is also essential because the teeth are sensitive to cold. Mouth breath ing under these conditions parches the pharynx. Agazzotti advises holding a swallow of water in the mouth at frequent intervals. The nostrils must be kept clean. Flights should be forbidden if the nasal passages are obstructed. MENTAL STATE. Intellectual faculties and special senses are under a great strain during flight. When the psychic state is in good balance, flying is a source of pleasure. With the nervous system in perfect equilibrium, resistance to high altitudes is greatest; the reverse holds when the aviator is dispirited, fatigued, etc. Every sort of entanglement caus ing mental preoccupation and worry makes for casualties. Three seconds give time for irreparable disaster. ALCOHOL. Aviators commonly hold that a moderate dose of alcohol raises the courage in the face of danger. Experience and physiology teach the very opposite of this. .Vo. 1. 45 BELLI—PERSONAL HYGIENE OF AVIATORS. When alcohol is used, after a fleeting period of excitation, there is a paralyzing effect on the nervous system and especially on the higher centers —in the psychic faculties. The abuse of alcohol suspends inhibition; if persisted in alcohol wholly incapacitat«s a pilot for handling his machine. Casualties among troops on high mountains during the war showed corresponding disadvantages of alcohol. According to Mosso, mountain troops should not go into action on the day following holiday celebrations, etc., and I consider this still more important in the matter of flying. Italian aviators are noted for their sobriety. Neverthless caution may properly be enjoined regarding use of alcohol prior to flight. Of course the ordinary wine with meals is not harmful. TOBACCO. Usually aviators smoke too much. Tobacco damages the system partly through the action of pyridine bases, partly through the tollidine, carbon monoxide, and other substances formed during com bustion of cigars and cigarettes. Tobacco has local action— irrita tive and congestive —on the mucous membranes of the mouth, pharynx, Eustachian tubes, and even on the tympanic cavities—also a general toxic and depressing effect on the central nervous system, nerves of special sense, and particularly on the optic nerve. During the war numerous casualties were attributed to tobacco, hence aviators should be most abstemious in the matter of smoking. DRUGS. Aviators very commonly resort to drugs like aspirin, phenacetin, and to secret remedies against seasickness to avoid discomforts of high altitudes. This is a bad habit which only masks the real situa tion and often leads to casualties. Narcotics such as cocaine, mor phine, and opium are of course the most dangerous. It is imprudent to fly after generous doses of quinine. PREPARATION FOR FLIGHT. The aviator who feels indisposed and is lacking in confidence should refrain from flight and consult the doctor because ailments that are negligible on the ground may seriously handicap the physi cal and psychic side of the aviator and seriously reduce his capacity for flight. After sickness or accident the aviator should always be reexamined by a physician. According to Guilbert the old precept " head cool, feet warm, belly clear " is as valuable in aviation as in any other contingency of life. The intestinal functions should be carefully regulated. Symptoms of intoxication may arise from constipation and destroy 46 BELLI PERSONAL HYGIENE OF AVIATORS. Vol. XVII. the fineness of perceptions. Kidney functions should also receive attention. Aviators should always empty the bladder before climb ing into the machine. At high altitude ultra-violet rays combined with the cold lead to erythemas and chilblains. Mosso has shown experimentally that the best protection for the skin is to smear it with burnt cork. This method has never become popular. Instead most aviators prefer vaseline, lanoline, or cold cream. These agents protect the skin from rapid evaporation, but not from the ultra-violet rays. PROPHYLAXIS OF HIGH-ALTITUDE SICKNESS. The first symptoms, confined to the sphere of the vegetative func tions, are usually well tolerated by most men. Very few, however, can withstand the later developments involving the neuro-psychic feature. Of these, sleepiness is the most constant sign and indicates depression of the nervous centers. When it develops the aviator should come to the ground. The primary cause of these disturbances is reduced atmospheric pressure. This is not the place to discuss the details of etiology ; whether it is due to insufficient exchange of oxygen between the air and the blood or to diminished tension of carbon dioxide in the blood. Mosso thought the administration of oxygen useless in mountain sickness, but admitted that it had some value when taken at an ele vation above 7,000 meters. English and American physicians be lieve that oxygen saved the lives of many aviators during the war. Oxygen can not be employed by the apparatus commonly used in medicine. Special apparatus is necessary for aviators. It must be easy to handle and not interfere with movement. The aviator's hands must be free. The inhalation must be by means of a mask and entirely automatic, that is to say, the oxygen feed must accom modate itself automatically to the requirements of changing eleva tions. The apparatus devised by Colonel Dreyer has been used with satisfaction in the American Aviation Corps. Mosso insists that carbon dioxide should be distributed along with the oxygen. Agazzotti has shown by experiments with the pneu matic chamber that the proportion giving the best results is 15 to 20 parts carbon dioxide and 85 to 80 parts oxygen. As the effects of oxygen persist for four to six minutes after inhalation has ceased, the gas should be repeated at intervals of not more than six minutes. Administration of oxygen should be the rule, not the exception, when the aviator has reached the height of 3.000 or 4.000 meters. Oxygen may be used to advantage when the aviator lands after a long flight to overcome as quickly as possible his sensations of fatigue. No. 1. 47 GALWEY —GAS WARFARE. GAS WARFARE: ADOPTION, METHOD OF USE, PROTECTION OF TROOPS.1 By Maj. W. R. Galwey, O. B. E., M. C, Royal Army Medical Corps. The legitimacy of the employment of noxious gas as a weapon of warfare has recently been much discussed in both the public and scientific press. At the meeting of the British Association in Edinburgh in Sep tember, the president in his opening address, called upon the asso ciation to use its every endeavor to persuade scientists to cease research into chemical methods of destruction as derogatory to the high call of science. Much might be said regarding the humanity of inflicting casual ties by gas rather than by high explosive, of the high percentage of permanent recoveries after the former as against the latter and the low percentage of deaths, but it seems to me that two fundamental facts are ignored by those who write and speak against gas war fare: (1) That, in the highest sense, all weapons in war are inhuman; and (2) That the use of gas in warfare is an accomplished fact. It has proved a most effective weapon, so that any nation fighting in the future for its existence must be prepared to combat it and use it. Research into new compounds capable of overcoming exist ing methods of defense can be carried out in secrecy in the laboratory without attracting the attention of foreigners—many of the poison ous compounds are intimately connected with the chemical indus tries. Therefore it appears that so long as war remains the ultimate means of settlement of international strife, and until the League of Nations can enforce its mandates, so long must each nation continue to prepare for gas warfare. Two facts are significant: (1) During the inquiry into German methods of making mustard gas which followed the armistice one of the respondents asked: "Why are you worrying about this, when you know perfectly well that this is not the gas we shall use in the next war." (2) Of the total American casualties, about 30 per cent were due to gas, and of these about 90 per cent were due to skin burns ; of the gas casualties 3 to 4 per cent died and about 95 per cent recovered completely. The Americans have laid to heart the lesson taught by these figures and have established a Chemical Warfare Service on a peace footing with a personnel numbering about 1,600 and have budgeted for an annual expenditure of $4,500,000 for research into this branch of warfare. 1Reprinted from the Journal of the Royal Army Medical Corps, January, 1922. 48 GALWEY GAS WARFARE. Vol. XVII. Adoption. —In ancient times the Spartans in the fourth century before Christ, used gas in the form of sulphur and pitch fumes against the Athenians. Greek fire, which is of the same nature, was employed by the Byzantine (ireeks against the Saracens and by the latter in turn against the Crusaders. In modern times the' first suggestion to employ this method of offense was made by Lord Dundonald. It was seriousty advocated by the chemist, Lord Playfair, at the time of the Crimean War, as a humane method of overpowering the enemy, and the use of sulphur fumes was suggested as an aid in the reduction of the Redan redoubt. The suggestion was considered by experts and dismissed as in human. Later The Hague Convention, to which German}' was a signa tory, practically forbade its use. It was the treachery of Germany in this case as much as the nature of the weapon she employed which raised the storm of execration against her in April, 1915. At the end of the last century poisonous gases were investigated in Germany by Lehmann and his pupils with the ostensible purpose of making dangerous trades safe; but in England, although many of the compounds afterwards used had been met with in chemical research, practically nothing was known of their production on a large scale or of their action on the human organism. It is true, however, that useful work had been done prior to the war in South Africa by medical officers to mines in investigating cases of poison ing from nitrous fumes given off after the discharge of explosives in blasting operations. The first German gas attack was made against the French and our second army in the Langemarcke sector on April 22, 1915. The surprise was absolute and our line simply ceased to exist, since those who did not retire were either killed or incapacitated. The Germans captured 60 guns and a large extent of territory. A second cloud gas attack was delivered in the same sector on April 24. and was chiefly directed against the Canadians. The Germans did not realize the power of the new weapon and neither used it over a sufficient extent of front nor followed up their initial success. Had they done so the war might have ended in a German vic tory by the summer of 1915. The first attacks were quickly followed by others, some of which were on a large scale, during the months of April and May; all were in the Ypres sector. The gas used in the early attacks appears to have been pure chlorine, though later phosgene was combined with it. It was deliv ered from steel cylinders, each of which contained some 45 pounds of compressed chlorine. No. 1. 49 GALWEY GAS WARFARE. Gas attacks followed each other rapidly until May 24, and then there was a lull until December. 1915. The last cloud gas attack was on August 8, 1916. Various statements have been made as to when the Germans first began to use lethal gas in projectiles. The earliest certain date is July, 1916, when lethal gas shells were used, and from that time the enemy developed this mode of attack more and more. In all he used no less than 18 different gases against us and our Allies. It is unnecessary to detail these, and in my next paper I hope to put be fore my readers a classification of war gases according to their pathological effects. It will suffice to say here that the three main types of gas shell were known as green cross, blue cross, and yellow cross. The green cross contained phosgene alone, or combined with such substances as chlorpicrin and chlorarsines. Green cross 3 con tained various arsenic compounds. Blue cross contained chlorar sines, cyanarsines, and N. ethyl carbazol. Yellow cross contained dichlorethyl sulphide or mustard gas. At first gas shells were fairly easily distinguished from others, owing to the small bursting charge they contained, but later they were mixed with bombardments of high explosives, and the gas shells themselves contained large quan tities of high explosives; so that it became difficult to say whether a bombardment was simple or mixed, and a constant outlook had to be kept for gas. Gas warfare reached its zenith in 1917 when the Germans intro duced mustard gas—a weapon, which although of minor importance from the point of view of death, causes a great number of casualties from its insidiousness and persistence and which can be used to render ground untenable by troops for considerable periods. The last development was the use of large projectors which dis charged by means of bombs enormous quantities of gas over small areas, so that concentrations were arrived at when one breath in capacitated if it did not kill a man. The projector attack was in troduced by the British in April, 1917, and adopted by the Germans in December of the same year. I may mention that toward the end of the war our use of gas far surpassed that of the Germans, as our defense was better; so that they were very literally hoisted with their own petard, and must have bitterly regretted their treachery in introducing this weapon. Methods of use.—As the science of gas warfare was developed, three definite purposes emerged for which this weapon is effective : (1) To inflict casualties; (2) to reduce the fighting efficiency of troops by compelling them to wear respirators; (3) to render posi tions temporarily untenable. 1. The best substance to employ is that which answers the par ticular purpose of the general staff, and the fact that a substance is 50 Vol. XVII. GALWEY GAS WARFARE. lethal need not necessarily give it preference over one whose effects are only temporary and do not permanently incapacitate, but which quickly puts men out of action. Thus a lachrymator might in par ticular circumstances be more effective than phosgene. The first gas attacks caused very numerous casualties but it is impossible to estimate numbers with any great degree of accuracy as so many men were killed outright or died before they reached medical units. But as our defense developed the casualties dimin ished, so that in the last cloud attacks they were confined to units, and individuals, where gas discipline was slack or defensive ap paratus was not properly cared for or adjusted. With the advent of mustard gas the casualty list lengthened until the troops had again learned how to combat this new evil. 2. The second purpose for which gas is employed —to diminish the fighting efficiency of troops—is more difficult to combat. The respirator is uncomfortable to wear, and if worn for any length of time the resistance to breathing and general discomfort diminishes the fighting and working power. The greatest sources of discomfort are the mouthpiece and nose clip, but, so far, it has been impossible to dispense with them. In tercommunication and accuracy in handling delicate instruments also suffer. Two examples will illustrate how efficiency is impaired : (a) It was noted that if, when shelled by the enemy, our batteries replied with gas shell, in 20 to 30 minutes the accuracy of the enemy's shooting, as indicated by " qvers," " duds," etc., was greatly dimin ished. (b) The French experimented to see how long men could wear respirators. An area was chosen in the rear, where men were made to carry out light work or left at rest wearing respirators continu ously and not even removing them for food or drink. The men were exposed to a gas, nonlethal, but causing intense lachrymation with the least dose. Forty-eight hours' leave was given to each man for every two hours he could stick it over six hours, but though a certain number of men managed to accumulate a considerable spell of leave, the best result that could be obtained was that 70 per cent were effi cient at the end of 24 hours. The French mask is more comfortable than ours. 3. The third purpose for which gas is used is to render posi tions untenable. Mustard gas has so far given the best results on ac count of its persistence. It is therefore imperative when occupying a position which has been shelled to make certain whether gas has been used and to warn troops against handling objects which might be contaminated, and against drinking water contaminated by gas. Numerous casualties were caused in France by neglect of these pre cautions. No. 1. 51 GALWEY —GAS WARFARE. Though the means by which an enemy attains his object in a gat attack, i. e., gas tactics, is primarily the business of the general staff and gas services, it is important that all troops, officers, and men alike, should understand the general idea in the use of gas. Cloud gas is used to inflict casualties and as a preliminary to an infantry attack. The gases used must have the following properties: (1) Must be heavier than air; (2) must be easy to liquefy; (3) must be lethal in fairly low concentration. Not man}7 substances fulfill these conditions, and for this reason and because our protective measures had become almost perfect against it, the Germans abandoned the cloud attack. Weather conditions must be closely considered with all kinds of gas warfare but they are particularly important in cloud attacks. The best wind is a steady breeze from 4 to 9 miles per hour, but attacks have been made with winds from 2 to 20 miles per hour. The effects of cloud attacks has been felt as far back as 20 miles from the point of liberation, but the usual distances for serious casualties is 5 to 6 miles. Heavy rain is unfavorable, but slight dampness keeps the gas low —fog gives opportunity for surprise. Nighttime is most favorable both on account of surprise and be cause cold currents coming downward keep the gas low. The usual number of cylinders employed was one per yard of frontage and the front attacked was about 3,000 yards. An attack can be recognized by the hissing noise as the gas emerges from the cylinders and by the greenish color (becoming white in damp weather) of the cloud in the case of chlorine. Gas shells are used both for surprise attacks and to inflict casual ties, and also to harass communications and prevent arrival of re inforcements. The news of a cloud attack can be quickly passed to the rear, but the gas shell is its own herald. In the last stages of the war the only way of recognizing gas shells was by the smell of the compounds they contained. The projector attack combines the advantage of both cloud and shell and is more deadly because of the enormous concentration which it can give. The projector discharge can be recognized by: — (1) Noise on dis charge— like an ammunition dump going up, (2) flash along the line, (3) whining noise of the drums in flight, (4) sight of drums flying, (5) at night by the trail of sparks emitted from the drums. For a big projector attack as many as 1,500 drums, each containing some 31 pounds of liquid, were used, one drum being sufficient to overcome the German respirator at the point of impact. 52 Vol. XVII. GALWEY —GAS WARFARE. It has been well said that " Gas warfare resolves itself into a con test between offensive materials and protectice devices, and there is no finality in regard to either; so that the chemical substances em ployed must necessarily vary from time to time, as well as the tactics adopted to using them." Protection of troops. —Though the first attack found us totally un prepared, efforts were at once made to counteract this new weapon. On April 23, under telephone instructions from the Director General Medical Services, General Headquarters, the Director of Medical Services, First Army, issued a circular recommending the use of a solution of bicarbonate of soda, which should be kept in buckets, etc., and that men should be instructed to use handkerchiefs or cloths dipped in the solution to cover the nose and mouth. On the following days various other appliances were improvised : for instance, on 27th and 29th, Professors Haldane and Baker visited France, and the latter recommended the use of cloths, etc., moistened with urine, or of earth folded in cloth or inclosed in a bottle from which the base had been removed. A German respirator captured at this time proved to be a pad of cotton-waste soaked in hyposulphite solution and contained in a gauze bag which was provided with tapes for tying over the face. In the meantime the War Office authorities at home had turned to the Army Medical Service, and it was very largely due to the scientific knowledge and unfailing resource and energy in organiza tion of Col. Sir William Horrocks and Colonel Lelan that the menace to our troops was met and disaster averted. It was known that for the moment chlorine was the gas to be dealt with, and the chemical problem was therefore simple, though the pro vision of the appliances for making pads within a few hours was far otherwise. However, so nobly was the call met that within 60 hours 98,000 pads of cotton waste in muslin containers, dipped in hyposulphite solution and dried, were available at the front; 300.000 were avail able in a week, and 2,000,000 within a month. It was, of course, recognized that this provision was at most a tem porary expedient, the life of the pads was short, and they were not effective in high concentrations ; if a heavier charge of gas absorbent were added the obstruction to breathing became serious. Moreover, they were only effective against chlorine gas, and, once gas warfare had been established, it was obvious that the enemy could and would use higher concentrations and different and more potent substances. A research laboratory was therefore started in the Royal Army Medical College. The history of the evolution of our present pro tective apparatus records a story of untiring zeal, energy, and dogged pluck not surpassed in the story of scientific research. GALWEY— GAS WARFARE. 53 At the same time a research laboratory was organized in France and the closest liaison was maintained between workers at home and abroad. Every development in the use of gas was foreseen and pro vided for, so that our gas defense in a short time equalled and then surpassed that of the enemy. A brief account of the various types of protection evolved will serve to illustrate the problems which must be met and solved in chemical warfare. The original cotton-waste respirator was soon superseded by those of black veiling-cotton waste impregnated with hyposulphite of soda and glycerine. Two problems called for immediate solution : L To make the filtering area greater ; and 2. To make the absorbent substance such as would withstand not only chlorine but other gases which, it was recognized, might be used. The filtering area was increased by substituting a helmet for a pad. thus providing an area of 3£ to 4 square feet through which the air could enter and reducing the resistance to between 0.3 and 0.5 inch of water. The air current was also slowed so that the absorb ent had more time to neutralize the noxious gas. Suitable materials had to be found and in sufficient quantities. After a few days of testing on individuals a manometric device was devised for rapid testing at a definite standard pressure. The color of materials used in making helmets was also important, for if light colors were used men wearing the helmet's would furnish an easy target for enemy fire. The question of sight when wearing the helmet was also a knotty problem. At first mica windows were used, but these proved too brittle: cellulose acetate and chromicized gelatine were also unsuc cessfully tried. Finally nonsplintering triplex glass disks fixed in tin rims that clamped the textile of the helmet firmly by being screwed into flanged collars were adopted and proved most suc cessful. Polyvalency of the absorbent was first secured by adding sodium carbonate to the thiosulphate of soda and glycerol. This helmet could be donned in four to six seconds, gave 10 times as great pro tection as the pad, while its effective life against chlorine at a con centration of 1 in 1,000 was five hours. A new solution was made necessary by the fact that the absorbent afforded no protection against phosgene (carbonyl chloride) or hydrocyanic acid, and sev eral other gases. An effective absorbent was, however, found after many trials in sodium phenate, but it was found that the solution rotted the woolen fabric of which the helmets were made. This difficulty was met by adopting a cotton material which took up more alkali, and for a double thickness of cotton gave a resistance of 0.2 54 Vol. XVII GALWEY— GAS WARFARE. to 0.3 inch of water, as against 0.5 inch for a single thickness of wool. The problem was further complicated by the discovery that the CO> given off in expiration neutralized the protective alkali, so that after a time it ceased to protect against HCN. It therefore became neces sary to provide a valve through which the wearer could expire and so get rid of his CO* outside the helmet. The simple and effective respiratory valve still in use was the outcome of this research. One more addition to the absorbent impregnating the helmet was made in January, 1916, i. e., hexamin—suggested by Russia —this substance removed the remaining phosgene (carbonyl chloride) which had escaped the sodium phenate. With this final improvement the P. H. helmet, as it was called, removed 100 per cent of 1 in 1,000 phosgene and HCN. Of these helmets, from the first issue in July, 1915, until the final withdrawal in February, 1918, in favor of the box respirator as the sole issue, nearly 27,000,000 were made —many were supplied to our allies as well as to our own troops. In addition to protection against lethal gases of the asphyxiant type, protection had to be afforded against a group of substances known as lachrymators whose chief action is on the eyes. The majority act in minute proportions so that as small a quantity as one part per million causes intense lachrymation which throws the victim out of action. These lachrymators were first used against us in the autumn of 1915, and the first protection against them sent to France was a goggle of rubber with glass eyepieces similar to motor goggles. This failed in many cases owing to the difficulty of obtaining close adjustment over the bridge of the nose. To obviate that trouble the French pattern was next adopted. This was of impervious cloth with flannelette lining and celluloid eyepieces, the fit over the bridge of the nose being obtained by malleable wire sewn into the lower edge of the fabric. These were found service able against low concentrations, but against higher concentrations the best fitting results were obtained with rubber sponge. In a final pattern the base was of stiff impervious fabric (gelatine for malin impregnation) lined with soft material to which were cemented and sewn the two halves of an oval sponge —holes being cut in the sponge and the base into which were fitted screwed metal and glass (helmet) eyepieces. Elastics were provided for attachment. The P. H. helmet was also fitted with rubber sponge round the eye pieces and was issued as the P. H. G. helmet. Goggles were finally withdrawn after the issue of the box respira tor, since they tempted a man to put on his goggles rather than his respirator, and so continue to inhale small quantities of gas which would have a cumulative effect. No. 1. GALWEY GAS WARFARE. 55 No helmet could ever be completely polyvalent. For one thing it is impossible to impregnate so thin a layer of material with both oxidizing and reducing substances. The realization of this fact led to the research which culminated in the production of the present box respirator. The object was to produce a container filled with strata of different absorbents, through which air could be drawn —each group of noxious gases being removed or neutralized in its appro priate stratum. The box respirator was issued only one montli be fore the enemy attacked with gases which the helmet could not have withstood. Very extensive and exhaustive trials were made by Lieutenant Colonel Harrison and his colleagues before a granule was made which was sufficiently active, and at the same time hard enough to with stand the shaking and general rough usage which the respirator must necessarily undergo and yet remain active. The box respirator was originally charged with successive layers of: Sodium sulphite (reducing) ; soda lime manganate (neutralizing and oxidizing) : animal charcoal (absorbing and condensing) ; each layer being separated by plaques of cellulose. This was found to be completely polyvalent against every gas which the enemy had then used against us, and to give very slight resistance to respiration. It was efficient against carbonyl chloride for three hours, against chlorine for eight hours, and withstood a sequence of six gases run through it in succession, each for one hour. But it was found that gas tended to pass up the smooth interior against the side of the box so that this channel became ineffective, whilst the remainder of the box remained effective. This defect was remedied by corrugat ing the sides of the box and so lengthening this route, leaving large air spaces above and below the absorbent layers to equalize the flow and by arching the base of the lowest absorbent layer so as to divert the flow from the sides. Two valves were necessary —an inspiratory flap valve in the base of the box and an expiratory valve, like that in the helmet, between the mouthpiece and the box, so as to prevent ex pired COj, neutralizing the soda-lime-alkali. A closely fitting face piece with eyeglasses and nose clips was added. The whole ap paratus could be adjusted in 25 seconds [since reduced to 10 seconds]. There were several slight modifications of the box respirator, and the small box respirator as at present in use replaced all other gas protection appliances in February, 1918. Work is still being carried out on it to make it more perfect and to decrease its resistance to the passage of air to the lowest possible amount. The resistance of the present pattern is equivalent to about 3 inches of water. 56 Vol. XVIL GALWEY —GAS WARFARE. The above sketch of the evolution of the methods of individual protection against lethal gases will show you the essentials to be aimed at in devising such apparatus: 1. The apparatus must be capable of very rapid adjustment. 2. It must be able to neutralize all forms of noxious gases and clouds and vapors which may be used against the troops wearing it for a reasonable length of time. 3. It must offer as little resistance to breathing as possible so as to avoid diminution of the working powers of troops. 4. It must be strong and light. The box respirator has, so far, resisted all gases used against us, but it will be readily understood that constant research in defensive measures must proceed pari passu with new discoveries of substances which may be used in chemical warfare. The soldier must be taught that if his respirator is kept in good condition, and he has learned to adjust it with the necessary quick ness, he can place complete reliance upon it. Very frequent inspection of respirators is necessary to see that they are in good condition. Periodical inspections are carried out by the antigas officer with the formation concerned, but it is the duty of all officers commanding units or sections of units to see that their men's gas equipment is thoroughly effective. The most serious causes of damage to the respirator are : (1) Water entering the container and damaging the chemicals, (2) injury to the mask, (3) injury to one or both valves. It is of the utmost importance in reference to (2) and (3) to see that nothing is carried in the satchel but the respirator and anti- dimming outfit for cleaning the eyepieces. I hope to deal with the question of the disinfection of respirators in my last paper. The container, as finally issued, should be replaced after it has been breathed through for 40 hours. A record card is therefore issued with each container, and on this should be entered the time during which the apparatus has been worn during cloud gas attacks or gas shell bombardments. The number of hours during which the respirator has been breathed through for training are entered in the bottom three rows under shell gas. The date of issue is also stamped on the card. A fresh card is issued with each container. I have dealt above with the apparatus supplied for the protection of troops, and it is unnecessary to do more than remind you that in gas warfare everything depends upon the quickness and efficiency with which troops apply their protection. It is, therefore, necessary in preparation for war. to train all troops thoroughly in gas drill, i. e., in systems adopted for spreading gas alarms, in recognizing conditions whether of weather or environment when gas may be used, Xo. 1. 57 GALWEY GAS WARFARE. and in recognizing when gas shell is being used and the type, and in circulating information to all who may come into a gassed area. In conclusion, therefore, I will refer briefly to the secondary means of protection against gas attacks. ,1. When cloud gas attacks were made, various methods were adopted to disperse the gas, e. g., firing and throwing bombs in the gas; lighting fires in the trenches. Fans were also supplied for re moving gas from dugouts and trenches. 2. Solutions of hyposulphite and hexamine with sprayers were also issued for spraying the air in trenches, dugouts, etc. 3. With the development of gas warfare and the use of lethal gas shells these methods had to be revised, and additional measures taken for the protection of important dugouts, pill boxes, and aid posts. It was recognized that if possible the dugout should be evacuated until the gas had dissipated, but short of this it was found that an effective measure was to light a fire in the middle of a dugout after a gas bombardment. It was necessary to take care that the ground outside the dugout was free from gas before the fire was lighted, otherwise the fire merely drew the gas into the dugout. In the case of dugouts which could not be evacuated —e. g., aid posts, advanced dressing stations, headquarters —a gas-proof curtain was devised as a method of protection. One method of applying this curtain is as follows: A frame of 4 inches by 1 inch timber covered with blanket material is fixed flush with the wall, sloping outwards at an angle of 20° from the vertical. Antigas material — i. e., a special cloth to be treated with a solution of sodium thiosul- phate and sodium carbonate in water—is cut to the required size, so that when fastened to the top of the frame it will close the en trance completely and leave about 9 inches resting on the ground. Three pairs of laths are nailed horizontally to the curtain to keep it stretched. The lath on the underside must be left shorter than those in front so as to clear the frame. The lowest of the laths should be 4 inches from the ground but must not touch it. Two curtains should be provided, the upper as near the top of the stair case as possible (otherwise a pocket of gas may lodge and be carried into the dugout). The frame for the inner curtain should, if pos sible, slope inward. A similar contrivance was used to protect pill boxes. When mustard gas came into use it became necessary to protect men handling objects contaminated with it and to find some means of removing it from clothing. For men specially liable to contamination—e. g., gunners and stretcher bearers —in addition to their respirators special gloves were provided. After trial of various substances leather gloves treated 58 Vol. XVII GALWEY —GAS WARFARE. with unboiled linseed oil were found efficient. With them two pairs of cotton gloves were issued to be worn over the leather. Although efficient in preventing burns, these gloves were large and clumsy and hindered delicate manipulation. To obviate the hardening of the leather with age the Americans adopted: (1) Gloves of a waterproof material coated inside with gelatine-glycerine- formalin composition and protected outside by another waterproof coating, and (2) gloves of a fabric coated with a softened layer of cellulose nitrate. An effort was made to provide clothing which would withstand mustard gas. We used cloth treated with boiled linseed oil, and the Americans cotton sheeting impregnated with boiled linseed oil, castor oil, and paraffin wax. These proved efficient, but difficulties of transport and of readi ness when wanted were great obstacles to their use. To destroy mustard gas in clothing three methods were tried : (1) Treatment with steam or hot water; (2) treatment with chlorine gas; (3) exposure to fresh air. As heavily contaminated or directly splashed clothing can not be effectively cleaned without damage to the cloth, it is considered that it should be buried. Treatment with steam is the surest method of degassing contami nated clothing, and this can be effectively carried out by means of Colonel Lelean's sack disinfector or in a plant of any delousing sta tion. The Americans found hot (not quite boiling) soapy water effica cious. The French used water at 90° C. containing mild alkalis to neutral ize the acid formed by hydrolysis of mustard gas. A solution of washing soda is safe, but it must be in correct pro portions; too much or too little retards destruction of the mustard gas. Keeping men whose clothing has been contaminated in a chamber containing 1 per cent chlorine for five minutes have been found effec tive. This treatment can be carried out with cylinders of chlorine gas in dugouts. For slight contamination exposure of clothing in open air for 48 hours suffices, but if the contamination is heavy or the weather cold, a much longer time is necessary. Dugouts may frequently be contaminated by infected mud brought in- on boots. Washing with a stiff brush and water and sprinkling with chloride of lime have been recommended. If dugouts are contaminated, it is well to evacuate and destroy them. If this can not be done, the contaminated soil and beams should be removed, the walls and floor treated with chlorine, and the No. 1. 59 RAYNOR MEDICAL CORPS UNITS. dugout shut up for 24 hours. After this period it should be well ventilated by placing a lighted brazier in it and shifting the position from time to time. The atmosphere may be slightly lachrymatory for some time, the chlorine masking the smell of mustard. Chloride of lime may also be used for this purpose and for treat ing shell holes. In the latter case the lime should be covered with fresh earth, the latter being employed to prevent chlorine masking the smell of mustard and to render the hole less conspicuous. Two pounds of chloride of lime per square foot of surface gives excellent results, but this amount is prohibitive. One-half to 1 pound gives fair results. In the time at our disposal it has only been possible to outline the chief points in measures of protection. Everything depends upon efficient preparation and training and in the impressing upon the troops that given these they may have every confidence that they will escape unscathed. THE FUNCTIONS AND ORGANIZATION OF MEDICAL CORPS UNITS SERV ING WITH THE MARINE CORPS IN THE FIELD, i By S. N. Raynor, Major, United States Marine Corpa. THE ORGANIZATION OF THE BRIGADE. [Introductory Note. —The writer has undertaken to prepare for the United States Naval Medical Bulletin a series of articles dealing with the functions and suggested organization of Medical Corps units serving with the Marine Corps in the field. Up to the present time there has been no special organization for that service. If the necessity for such special organization can be demon strated, the quo animo of this series shall have been attained.] Before taking up the question of the organization of Medical Corps units for service with the Marine Corps in the field it seems advisable to devote some time to a consideration of the organization of the military or fighting units. In general, the function of the Medical Corps during active operations is to provide sufficient per sonnel for first aid and part of the litter evacuation. It is obvious, therefore, that the organization of the Medical Corps personnel attached to any fighting unit must be governed primarily by the organization and functions of that unit. 1In the editorial section of the January issue of the United States Natal Medical Bulletin reference was made to the establishment of a correspondence course for naval medical officers to be conducted by Maj. S. N. Raynor, United States Marine Corps. It is believed that this course offers many advantages to medical officers, particularly those serving with the Marine Corps in the field. The Surgeon General is desirous of having all niedical officers who are available for duty with the marines enroll ifor tills course. Applications should be forwarded promptly to MaJ. Raynor at the Marine Corps Schools, Marine Barracks, Quantico, Va. The maps used in this course will be supplied by the Bnrean of Medicine and Surgery. 103390—22 5 60 Vol. XVII. RAYNOR —MEDICAL CORPS UNITS. At the present time the largest organization in the Marine Corps is the brigade. In this article, therefore, we will take up the organi zation of the brigade and of its component parts. As a result of the experience gained in the World War, and after a careful and exhaustive study of innumerable reports and of the conditions which presented themselves in various phases of the war, the Army Tables of Organization have been completely revised. The underlying principle in the revision of the tables was to provide organizations that would meet all the requirements for field service under conditions of modern warfare. As the reasons for using the Army Tables of Organization may not be manifest to all, a brief explanation may not be inappropriate. While the Marine Corps normally functions in conjunction with the Navy, Marine Corps forces may be, and, in recent years, fre quently have been, detached for service with the Army. Such being the condition which must be met, the Marine Corps organization and that of any Medical Corps units serving with the marines, should be such as to fit in with, and readily function with and as a part of the Army machine. While the Marine Corps organization differs in many respects from that of the Army, due to the nature and diversity of the duties which it is called upon to perform, this dissimilarity is one of practical adoption to conditions of service rather than the result of any divergence in the fundamental principles underlying their respective organizations. By analyzing the Army organization, in so far as it concerns this problem, we should get a picture of a machine whose efficacy has been proven, and thus enabled to more readily determine our own requirements. In the Army an Infantry division is composed of two brigades of Infantry and various auxiliary troops and services. A brigade, as a part of a division, is a purely tactical unit; i. e., it has no ad ministrative functions. When a brigade is detached from the di vision for independent duties it becomes necessary to provide an administrative staff along the lines prescribed for that of a di vision. (StafF organization will be the subject of a subsequent ar ticle.) The new infantry brigade is organized as follows : Brigade head quarters (10 officers) ; headquarters company (1 officer, 1 warrant officer. 88 enlisted men) ; 2 regiments of Infantry (each consisting of 103 officers, 1 warrant officer, and 2,950 enlisted men). Attached to each regiment are 11 medical officers, 87 enlisted men (Medical Corps), and 2 chaplains, making an aggregate for the brigade of 243 officers, 3 warrant officers, and 6.162 enlisted men. (See accompanying diagram). No.l. RAYNOR MEDICAL CORPS UNITS. h0 z 0 < •< u as o o as fe 1 0 £ si w ' 2 E c w « o U _ 9 ^ o So 62 Vol. XVII. RAYNOR—MEDICAL CORPS UNITS. It will be noted that no provision has been made for brigade sur geon and the necessary personnel to assist him. As will be seen later, this is because the regimental surgeons function under the di rection of the division surgeon when the division is intact. When a brigade is acting independently it is necessary to assign a medical officer to it for duty as brigade surgeon, and a quota of officer and enlisted personnel from the medical regiment of the division from which the brigade has been detached. This personnel, when so assigned, forms, for the Medical Corps, a brigade headquarters de tachment which functions as a part of the brigade staff. HISTORICAL. JONATHAN COWDKBY, SURGEON IN THE UNITED STATES NAVY, 1767-1852. PART 1. By Capt. F. L. PlbadwblI/, Medical Corps, United States Navy, and Lieut. Commander W. M. Kerr, Medical Corps, United States Navy. Jonathan Cowdery, the subject of this biographical sketch, was appointed a surgeon's mate in the Navy on January 1, 1800, and he lived to be the oldest officer in the service. A review of his life is not without interest to the medical officer of to-day for early in his naval career he took part in the war with Tripoli, was taken prisoner on the occasion of the loss of the U. S. frigate Philadelphia, and held cap tive by the Tripolitans for over a year and a half, during which time he kept a journal which throws much light on an historical event now almost forgotten. He was a descendant in the sixth generation from AVilliam Cow dery, who came to New England in 1630 from Weymouth, England, settling first at Lynn, Mass., and later at Heading in the same State, where he died in the year 1687. Jonathan Cowdery was born on April 22, 1767, at Sandisfield, Berkshire County. Mass. His father, Jabez Cowdery, was a physician who practiced his profession for many years in Tunbridge, Vt. His mother was Ruth Wickham, bora at Glastonbury, Conn. Where Jonathan received his medical education is not definitely known, but he probably served a quasi-apprenticeship with his father, and he appears to have attended lectures for two winters at Dartmouth in Hanover, N. H.. so it is not unlikely that this school was his alma mater. At any rate we find that by the time he had reached the age of 22 he felt himself qualified to support a wife, for in 1789, at New Marlboro, Mass.. he married Mary Bryant, daughter of Col. Richard Bryant, of Revolutionary fame. At this period of his life. Doctor Cowdery seems to have been somewhat of a rolling stone, for during the next six years he and his wife lived in three different localities where he practiced his pro fession. However, he was happy, as in each of these places a child came to bless his home. A son, Benjamin Franklin, was born in 1790, at New Marlboro, Mass.; another, Isaac Newton, was born in 1792, at Salisbury, Conn. In later years this child became a 63 64 JONATHAN COWDEBY, SURGEON IN U. S. NAVY. Vol. XVII. musician, playing the violin very skillfully. He taught music and penmanship. A daughter, Mary, was born in 1795, at Livingston, N. Y. She died the same year, and during the following year, 1796, Mrs. Cowdery died. After his wife's death Doctor Cowdery returned with his two sons to his father's home in Tunbridge. Leaving his children with his mother, he settled in the little town of Hudson, N. Y., where he was practicing medicine at the time he received an appointment as surgeon's mate in the Navy of the United States, as the naval force of the country was called in its early days. His commission was dated January 1, 1800, and was signed by John Adams, the second President of the United States. His first cruise was on the frigate Philadelphia commanded by the elder Commodore Decatur, in operations in the West Indies against the French. The first mention of him in official correspondence occurs in the following letter signed by Robert Smith, then Secretary of the Navy : Navy Department. 2S Oct. 1802. Doctor Jon. Cowdeby, Hampton, Virg". I have received your letter of the 19th instant and sincerely regret, as well on your own as on the public account, the occurrence that has deprived us of your services on board the John Adams the present cruise. On receipt hereof, you will consider yourself on furlough until again called into service and you will be pleased to report yourself to this department when you shall have recovered your health and are again tit for duty. It1 Smith. On July 18th, 1803, we find Doctor Cowdery once more sailing as one of the junior medical officers in the frigate Philadelphia, at this time commanded by Capt. William Bainbridge, United States Navy, for service in the Mediterranean against the Barbary States. The senior medical officer of the vessel was Surg. John Ridgely, United States Navy. The Barbary States, Morocco, Algeria, Tunis, and Tripoli, lie along the northern coast of Africa, between the Mediterranean and the Sahara, stretching from the Straits of Gibraltar to Egypt, a dis tance of 2,000 miles. The Mohammedan population of this strip of coast, consisting of Moors, Arabs, Berbers, and Turks, had long been engaged in piracy, especially since the Conquest of Granada in 1492, which was followed by the exodus from Spain of thousands of Moors who passed over to Africa carrying with them a hatred of the Spanish and a thirst for vengeance which early found vent in piratical raids on the commerce of Christian nations trading in the Mediterranean. These pirates continued to infest the Mediterran ean until their extermination in the nineteenth century. The captives taken in these raids were reduced to slavery and many of the pirates grew immensely and rapidly rich upon the No. 1. JONATHAN COWDERY, SURGEON IN U. S. NAVY. 65 plunder seized and the ransom of their captives. The redemption of slaves was procured with money raised by missions, contribu tions, and collections, and individuals and families sometimes im poverished themselves to ransom friends and relatives. William Eaton, United States consul at Tunis, writing of the corsairs in 1799, says : " Their mode of attack is uniformly boarding. For this their vessels are peculiarly constructed. Their long, lateen yards drop on board the enemy and afford a safe and easy conveyance for the men who man them for this purpose; but being always crowded with men, they throw them in from all points of the rig ging and from all quarters of the decks, having their sabers grasped between their teeth and their loaded pistols in their belts, that they may have the free use of their hands in scaling the gunnels or net ting of their enemy. In this mode of attack they are very active and very desperate. * * * Proper defenses against them are high nettings, with chains sufficiently strong to prevent their being cut away, buckshot plentifully administered from muskets or blunder busses, and lances. But it is always best to keep them at a distance, that advantage may be taken of their ignorance at maneuvering." " The attitude of Europe toward the Barbary States was cowardly and dishonorable from first to last. The action of the stronger powers was prompted largely by policy. In order to injure their enemies and to crush the commercial competition of their weak neighbors they were willing to bribe and subsidize the pirates, sub mitting to the indignity and dishonor of being tributary nations and encouraging a system of ruthless piracy and slavery."1 Shortly after the Revolution a new flag appeared in the Mediter ranean which the pirates soon learned to recognize as that of a young, weak power in distant America, likely to fall an easy prey to their vessels. Before long there were many Americans held in captivity in Barbary, who addressed letters and petitions to the Pres ident, to Congress, to the ministers of various denominations, and to Col. David Humphreys, United States minister to Portugal, who, in a letter to the American people, suggested a lottery as the means of raising the necessary funds for the ransom of their fellow country men. Various diplomats, commissioners, and agents were appointed to the difficult task of negotiating with the Barbary powers, but their efforts met with indifferent success. The rulers of the Barbary coast maintained that they were the sovereigns of the Mediterranean, and that no nation could navigate that sea without a treaty of peace with them. 1Out Navy and the Barbary Corsairs, by Gardner W. Allen. Houghton, Mifflin A Co.. Boston, 1905. 66 JONATHAN COWDEBY, SURGEON IN U. S. NAVY. Vol. XVII. In 1792, the Senate favored paying $100,000 annually for peace with Algiers, Tripoli, and Tunis, and $40,000 ransom for the captives; but many of the leaders of that time favored the early and energetic employment of force against these piratical States and through their influence three ships were built and launched in 1797, the United States, Constitution, and Constellation, forming the nucleus of the American Navy. A treaty of peace and amity with Algiers was ratified by the Senate, March 2, 1796, and it cost up to January, 1797, nearly a million dollars, exclusive of an annuity in naval stores valued at about $25,000. This treaty was not so liberal as one concluded with Mo rocco, but it was the only one which stipulated the payment of tributes. A treaty was also concluded with Tripoli and Tunis at great expense. Looking backward to those times it is easy to see how the em ployment of force would have saved time and money and won re spect for our infant nation, but, as Gardner W. Allen says, " to judge the question fairly it is necessary to look at it from the point of view of that time. Most of those who favored following the prec edent of Europe by paying tribute to barbarians, and who opposed a navy, did what they thought was best for the country and many of them were among the foremost public men of the day." The money received only enabled the rulers of the Barbary States to prepare for further depredations upon commerce and each waited for a pretext and opportunity to break peace with the United States. The pasha of Tripoli apparently did not make as good a bargain in the conclusion of his treaty with the United States as did some of his fellow pirates. Accordingly he became dissatisfied. Diffi culties arose between him and the American consul, Mr. Cathcart, and finally on May 10, 1801, the pasha declared war against the United States. Without delay he sent out his corsairs in search of American prizes but with little success, as his hostile act had been anticipated by the American Government and a timely warning had put American merchantmen on their guard. About June 1, 1801, a squadron under the command of Commodore Richard Dale, set sail from Hampton Eoads for the purpose of ob serving the situation in the Mediterranean and protecting American commerce against the threatened attacks of Tripoli. This squadron consisted of the frigates President,, 44 guns, flagship, Capt. James Barron; Philadelphia, 36 guns, Capt. Samuel Barron; and Essex, 32 guns, Capt. William Bainbridge, and the schooner Enterprise. 12 guns, Lieut. Andrew Sterrett. The squadron arrived at Gibraltar July 1. Here Commodore Dale found two Tripolitan cruisers which had left Tripoli with the intention of sailing into the Atlantic to prey upon American merchantmen off the straits, and by forestalling No. 1. JONATHAN C'OWDERY, SURGEON IN U. S. NAVY. 67 their passage through the Straits of Gibraltar he doubtless pre vented severe losses to American commerce. The Philadelphia was ordered to cruise in the straits and watch the Tripolitans, and the Essex was ordered to collect the American merchantmen in different ports and give them convoy through the straits. The commodore with the President and Enterprise cruised along the Barbary Coast where his appearance produced a salutary effect. During this cruise the Enterprise fell in with a Tripolitan vessel of 14 guns and 80 men. The two vessels were about evenly matched. They at once engaged at close range and fought for three hours. Allen gives the following account of the encounter and its results : " By his superior skill in maneuvering, Sterrett was able to avoid the enemy's attempts to board, and by choosing his position, to rake him repeatedly. Twice the Tripolitan struck his colors, and when he thought he had his adversary at a disadvantage, reopened his fire, hoisting his flag again. The third time, there being no longer hope of making up for his poor seamanship and gunnery by treachery or stratagem, he threw his flag into the sea, and by suppli cating gestures begged for quarter. Porter was then sent aboard the corsair to take possession. All her guns and small arms, with everything elese of value, were thrown overboard, and she was sent back to Tripoli an empty hidk. Sterrett's report to Commandore Dale, dated at sea August G, 1801, is as follows: 'I have the honor to inform you. that on the 1st August I fell in with a Tripolitan ship of War, called the Tripoli, mounting fourteen guns, commanded by Reis Mahomet Sous. An action immediately commenced within pistol-shot, which continued three hours, incessant firing. She then struck her colors. The carnage on board was dreadful, she having twenty men killed and thirty wounded; among the latter was the captain and first lieutenant. Her mizzen-mast went over the side. Agreeable to your orders, I dismantled her of everything but an old sail and spar. With heartfelt pleasure I add, that the officers and men throughout the vessel behaved in the most spirited and de termined manner, obeying every command with promptitude and alertness. We had not a man wounded, and sustained no material damage in our hull or rigging.7 Sterrett received the thanks of Con gress and a sword, and his officers and men a month's extra pay. The Tripoli crept slowly home, and on her arrival the pasha was filled with rage and chagrin. The unfortunate Mahomet Sous was mounted on a jackass, paraded through the streets, and bastinadoed. The effect of this severity was that men were greatly discouraged from serving in the corsairs then fitting out. For some time after this, very few Tripolitan cruisers ventured from port." 68 JONATHAN" COWDERY, SURGEON IN U. S. NAVY. Vol. XVII. The remainder of the year 1801, was devoted to a blockade of Tripoli, which was effectual in that it caused a great scarcity of food in the capital. In 1802 the American Government determined to prosecute the War against Tripoli with more vigor. As the terms of enlistment of Commodore Dale's men had nearly expired, it be came necessary to send out a new squadron to relieve the vessels in the Mediterranean. The command was given to Capt. Richard V. Morris, who hoisted his pennant on the frigate Chesapeake, 36 guns. This squadron having reached the Mediterranean, the Philadelphia, together with some of the other vessels, returned to the United States. Commodore Morris operated in the Mediterranean until the fall of 1803 when he was relieved of his command by Capt. John Rodgers by order of the Navy Department because it was believed that he was not producing the results desired. When it was decided to recall Morris, a new squadron was fitted out, the command of which was given to Commodore Edward Preble. Commodore Preble's instructions from the Secretary of the Navy, Robert Smith, were dated July 13, 1803. The vessels of the squadron sailed as they became ready for sea in the following order : Nautilus, 12 guns, Lieut. Richard Somers, June 30; Philadelphia, 36 guns, Capt. William Bainbridge, July 18; Vixen, 12 guns, Lieut. John Smith, August 3; Constitution, 4A guns, Commodore Preble's flag ship, Lieut. Thomas Robinson, jr., acting captain, August 14; Siren, 16 guns, Lieut. Charles Stewart, August 27; Argus, 16 guns, Lieut. Stephen Decatur, September 8. The Enterprise, 12 guns, Lieut. Isaac Hull, already in the Mediterranean, was to remain there as one of the new squadron, but on the arrival of the Argus, which was a larger vessel than the Enterprise, Hull, being senior in rank to Decatur, was to exchange commands with him. The Philadelphia arrived at Gibraltar August 24, 1803, in the vicinity of which place she cruised in search of enemy vessels, until on the arrival of Commodore Preble, she was sent together with the Vixen to establish the blockade off Tripoli before which port the vessels appeared on October 7. Bainbridge was informed by the captain of a brig, coming out of Tripoli, that two Tripolitan vessels of war were out upon a cruise. Thinking they were probably to the westward, he sent the Vixen to cruise off Cape Bon where these vessels would most likely be met if returning from that direc tion, and where it was safer for the schooner than off Tripoli, as the season for heavy storms was approaching. The Philadelphia from then on, maintained the blockade alone. On the last day of October an event occurred which, according to Allen, is narrated by Captain Bainbridge in his report to the Secre tary of the Navy, dated November 1, 1803, as follows: "Misfortune No. I. JONATHAN COWDEBY, SURGEON IN U. S. NAVY. 69 necessitates me to make a communication the most distressing of my life; and it is with deep regcet that I inform you of the loss of the United States frigate Philadelphia, under my command, by being wrecked on rocks between four and five miles to the eastward of the town of Tripoli. The circumstances relating to this unfortunate event are : At 9 A. M., being about five leagues to the eastward of Tripoli, saw a ship inshore of us standing before the wind to the westward. We immediately gave chase; she hoisted Tripolitan colors and continued her course very near the shore. About 11 o'clock had approached the shore to seven fathoms water, com menced firing at her, which we continued by running before the wind until half past 11, being then in seven fathoms of water; .and finding our fire ineffectual to prevent her getting into Tripoli, gave up the pursuit and was bearing off the land when we ran on the rocks in twelve feet of water forward and seventeen feet abaft. Immediately lowered down a boat from the stern, sounded and found the greatest depth of water astern. Laid all sails aback, loosed topgallant sails and set a heavy press of sail-canvas on the ship, blowing fresh, to back her off. Cast three anchors away from the bows, started the water in the hold, hove overboard the guns excepting some abaft to defend the ship against the gunboats which were then firing on us ; found all this ineffectual. Then made the last resort of lightening her forward by cutting away the foremast, which carried the main- topgallant mast with it. But labor and enterprise were in vain, for our fate was direfully fixed. * * * Striking on the rocks was an accident not possible for me to guard against by any intimation of charts, as no such shoals were laid down in any on board, and every careful precaution, by three leads kept heaving, was made use of on approaching the shore to effect the capture of a Tripolitan cruiser. And after the ship struck the rocks all possible measures were taken to get her off and the firm determination made not to give her up as long as a possible hope rema:ned. although annoyed by gunboats which took their position in such a manner that we could not bring our guns to bear on them, not even after cutting away part of the stern to effect it. When my officers and self had not a hope left of its being possible to get her off the rocks, and having withstood the fire of the gunboats for four hours, a reinforcement coming out from Tripoli, without the smallest chance of injuring them by resistance, to save the lives of brave men left no alternative but the distressing one of hauling our colors down and submitting to the enemy whom chance had befriended. In such a dilemma the flag of the United States was struck. * * * The gunboats in attacking fired prin cipally at our masts; had they directed their shot at the hull, no doubt but they would have killed many. The ship was taken pos 70 JONATHAN COWDERY, SURGEON IN U. B. NAVY. Vol. XVII. session of a little after sunset and in the course of the evening myself and all the officers, with part af the crew, were brought on shore." Captain Bainbridge was greatly depressed in spirits over the loss of his vessel. His officers sympathized deeply with him, and in a letter signed by all of them, November 1, 1803. expressed their feel ings in the following words : " We, late officers of the United States frigate Philadelphia, under your command, wishing to express our full approbation of your conduct concerning the unfortunate event of yesterday, do conceive that the charts and soundings justified as near an approach to the shore as we made, and that after the ship struck, every exertion was made and every expedient tried to get her off and to defend her. which either courage or abilities could have dictated." On November 2. a heavy wind caused the Philadelphia to float. The Tripolitans succeeded in pulling her off the reef the next day and brought here into the harbor, amid the rejoicing of the people and to the great mortification of the Americans. The officers and crew of the lost vessel had a long bondage before them. Doctor Cowdery kept a journal during his captivity which gives much information about the fortunes of the prisoners, and which will form the subject matter of the historical essay in the Bulletin next month. The officers Avere well treated at first, and were allowed some recreation on the roof of the house where they were confined, but after three or four days this privilege was denied them and soon they were removed to the prison where the men were con fined. Doctor Cowdery attracted the attention of the pasha, who employed him as his physician, and he was allowed more freedom than any other officer. The men fared much worse than the officers. The different classes of mechanics were put to work at their various trades, and the others were employed at all sorts of hard labor, chiefly on the fortifi cations. They were beaten and maltreated by many of their task masters, and sometimes basinadoed. When Commodore Preble heard of the Philadelphia's situation he determined to destroy her and selected Lieutenant Stephen Decatur for the task. On the night of February 16. 1804. with the Siren and the ketch Intrepid, Decatur entered the harbor of Tripoli and set fire to the captured vessel which, as Admiral Nelson said, when he heard of it, " was the most bold and daring act of the age." Without a doubt the burning of the Philadelphia added much to the reputation of the Navy both at home and abroad. In July, 1804. Commodore Preble assembled his entire squadron before Tripoli and on August 3. he began a series ot bombardments which lasted a month and which caused great destruction of the gun No. 1. JONATHAN COWDERY, SURGEON IN U. S. NAVY. 71 boats in the harbor, and much damage to the city. He was relieved by Commodore Barron, who continued the blockade. Two letters written by Doctor Cowdery after the bombardment throw some light on the condition of the American captives in Tripoli at this time. One letter dated November 7, 1804, and ad dressed to his father. Dr. Jabez Cowdery, at Tunbridge, Vt., is as follows : My Dkar Father, No doubt you have often heard of the loss of the Frigate Philadelphia, and the capture of its whole crew (by the Barbarians). Among whom is your unfortunate son. We were taken on the 31st of October, 1803, and entirely robbed of our property even the greatest part of the clothes on our backs were taken from us. Our seamen were immediately put to hard labor, without mercy, and have suffered much for the necessities of life. Five have paid their last debt to Nature, and five have turned Turk. Myself and fellow officers were permitted to occupy the house where our Consul Mr. Cathcart resided, while in Tripoli. On our first arrival, we signed a Parole of Honour, but have not been allowed to enjoy it. The Bashaw (or the head of the regency) compels me to exercise my profession in his Palace, and among his slaves; to relieve the distress of the latter is a pleasure to me. About the first of Feb ruary we were removed to the Castle and placed In close confinement under a powerful guard of Turks, who examined every paper and letter with the utmost scrutiny, to prevent our having any communication with our squadron off the town, which they much feared. What few letters we received from our friends are opened before we get them ; no doubt many have been suppressed. Mr. Nissen, the Danish Consul, has done us many favours, and is entitled to our utmost gratitude. We live in hopes of being liberated in due time, and In a manner that will do honour to our country whose service we were in, and whose wrongs we were avenging, when by a sad misfortune we fell into the hands of a Monstrous foe, who divested us of liberty and property, and plunged us Into a Prison, from thence we were removed to a more gloomy one, the dreary cells of a Castle, the gloomy walls of which bespeak the miseries of Christian slaves who erected them under the lash of Tyrants, the glimmering light of which Is admitted through an Iron grating in the top ; the doors are secured by large locks and bars of iron, and guarded by infamous Turkish soldiers, who are ready to plunge their daggers into our hearts, at the nod of a tyrant, who pre serves us only for the ransom which he expects from our country. We hope and expect that the Free Sons of Columbia will soon relieve us, their oppressed countrymen, and restore us to our native shore, that we may join them in the protection of its rights, and the enjoyments of its blessings. May the day soon arrive, when we may have the pleasure of joining our Country men hand in hand to erect dungeons for vice and tfmples for virtue. May we teach the haughty tyrant, and the barbarian that our rights, the common rights of man, are sacred, and not to be infringed, that we will establish and maintain them in spite of the enemies of Mankind. Ever since our captivity the Bashaw has been possessed in favour of me : I have had two fits of sick ness, one of the Dysentery and the other Ophthalmia, both very severe during which the Bashaw paid me every attention that could be expected from a Turkish foe. On the 30th of July lie took me from the prison of my brother officers, and gave me a pleasant and well furnished apartment in his palace; I now have liberty to walk about the town when I please, and to take a short ride into the country on a mule. Occasionally a Turk who speaks the English language, is appointed to walk and ride with me, to prevent my running away, 72 JONATHAN COWDERY, SURGEON IN U. S. NAVY. Vol. XVII. or meeting with insult, and to act as interpreter ; he is very polite and pays me every attention, I can speak Arabic (the language of the place) tolerably well ; I have received some of the books which were taken from me when we ran on the rock, them I make use of as my best companions, I spend the best of my time in perusing them and in attending the sick slaves, particularly my countrymen. I am not allowed to hold any conversation with our officers (and our letters to each other are examined with the utmost scrutiny) who are still in close confinement. Our worthy Captain Bainbridge has established a credit with Dr. Davis, our Consul at Tunis, and with the French and Danish Consuls In this place so that we draw a little money when we are in want, by this our seamen are often supplied with bread, or perhaps they would perish with hunger. The harbor is closely blockaded by the American Squadron under Commodore Barron, who lately relieved Commodore Preble, in consequence of which there is great scarcity of provision In this place, and I fear it will be worse among us before we get from hence. Our Squadron made five vigorous attacks upon this place last summer, in which much blood was shed. Terms of Peace have been offered, without effect. The Bashaw demands $1,000,000 of dollars. Our Government has offered through Commodore Preble one hundred and twenty thousand dollars, a very wide difference ; an additional amount is expected from our country in the spring, I suppose you know more of this than I do. We expect warm work next summer. I assure you It is not very pleasant to be a prisoner in a besieged city, but God is our protector. The present Bashaw has been on the throne about eleven years. On the death of his father, the former Bashaw, he usurped the throne, by killing one of his elder brothers, and driving the other out of the dominion Into Egypt. He is very cruel to his subjects, when he finds them guilty of crimes; for murder, treason &c he beheads them; for theft, housebreaking &c he takes off the left hand and right foot, at the Joint and dips the stump Into boiling tar ; for less crimes he gives them from five hundred to a thousand bastinadoes as the Turks call It; this is done by tricing up the feet with a rope and beating upon the soles of the feet with a large stick; they often perish under the operation. Yet this cruel prince is remarkably fond of his children, and kind to the poor. He Is about thirty-five years of age. He has two wives, one white and one black ; by the former he has five and by the latter four children, a plurality of wives Is allowed in this country. The Bashaw is a white man of middling age, rather portly, and tolerably handsome. He has a bombproof room, which he occupies during the rattling of shells and shot and the sounding of Colum bian Thunder. The laws of our country allow us full pay and rations during our captivity ; this is of some consolation to us In this savage land. How long we are to remain here, God only knows; I am in hopes of once more seeing my Parents, I wrote you a letter directly after our captivity. I have an oppor tunity of sending this letter to the Island of Malta by a particular friend, from thence it will be sent to America, by our Consul who resides near that place, it therefore will escape the scrutiny of my new masters; I am in good health and spirits, thank God, and hope for better times soon. My respects to all friends, I am with the greatest respect, Your affectionate son, Jon" Cowdebt. Dr. Jabez Cowdebt. The other letter, dated 24 November, 1804, was addressed to a friend, a Doctor Mitchell, and it was published in the National In telligencer at Washington, D. C, August 5, 1805. Dear Sib: I hope you will excuse me for the liberty I take in suggesting to you a few remarks which have occurred since my captivity. The Bashaw No. 1. JONATHAN COWDERY, SURGEON IN U. S. NAVY. 73 has taken uie from the prison where my fellow officers were confined ami ordered me to attend his sick slaves who are principally Neapolitans, negroes and our unfortunate crew. Some of the latter I this morning saw chained to a cart loaded with stones which they were dragging through the town to repair the fortifications. They complain much of hunger, cold, hard labor and the lash of the whip. I confess I never saw anything that wounded my feelings equal to the sight of those poor fellows. I have liberty to walk in the town but am attended by a Turk who is loaded with weapons of war. 1 am not allowed to visit any of the fortifications nor any of the foreign con suls. Capt. Bainbridge's endeavours to relieve the wants of his crew are often countermanded by our new masters. Five of our countrymen have turned Turk, and five have paid their last debt to nature. Diarrhea and Dysentery have often appeared among our crew, but on a free use of carbonate of soda (Natron) which is found in abundance in this country and often white wash ing the walls of the prison with lime where they sleep, it soon disappears. Our crew are not very healthy. During the several attacks upon this town by our squadron under command of Commodore Preble, many Turks were killed utid wounded and several men much burnt by the explosion of their own powder. I had an opportunity of seeing their method of curing burns in particular, many of which extended over the whole body. The Bashaw has all his wounded brought to an apart ment in the castle where he visits them and makes them a present of ten dollars each. He then orders his surgeons and Mamelukes to dress their wounds; he often assists with his own hands. The Mamelukes are his body guards; the Marabouts are employed to expell evil spirits, and make Inter cession with Mahomet their prophet, for their recovery. Those that were burnt, were first annotated with honey, carefully preserving the skin as much as possible and keeping the parts exposed to the air. They then sprinkled the ulcerated parts, if any, with a fine powder of white lead (Ceruse:) this they repeated at short Intervals until a scab is formed, that is carefully pre served until a cure Is accomplished, which is remarkably soon. I hope and expect that in due time my country will honorably and to the astonishment of Barbarians and Tyrants liberate us from the chains of slavery and restore us to our native land, that happy land the thoughts of which is a healing balm to our souls in their miserable bondage." Commodore Barron maintained the blockade through the winter of 1804-5, but his health at last became so impaired as to make it impossible for him to manage the affairs of the squadron. Accord ingly, on May 22, 1805, he turned the command over to Captain Rodgers, the commanding officer of the Constitution. On June 4, 1805, Captain Rodgers, together with Col. Tobias Lear, the American consular general at Algiers, who had been invested by the President with full power and authority to negotiate a treaty of peace with the pasha of Tripoli, effected an amicable settlement of the differences between that country and the United States. Colonel Lear in his report to the State Department, writing of the termina tion of hostilities says: " I went into the harbor in the Constitution's barge, with the flag of the United States displayed, and was received at the landing place by the American officers, who had been in cap tivity, with a sensibility more easily to be conceived than described. 74 JONATHAN COWDERY, SURGEON IN U. S. NAVY. Vol. XVII. An immense concourse of people crowded the shore and filled the streets, all signifying their pleasure on the conclusion of the peace. * * * On the 4th of June, at 11 a. m., the flagstafl was raised on the American house and the flag of the United States dis played, which was immediately saluted with 21 guns from the castle and ports and was returned by the Constitution." The American prisoners, after a captivity of over 19 months, were released and sent aboard the ships. On June 21 the American vessels left Tripoli, leaving behind as charge d'affaires, Surg. John Ridgely, one of the late captives and formerly the senior medical officer of the Philadelphia. Doctor Cowdery, as we see by the following letter, reached home in the fall of 1805. * . Tunbridqe, Vermont, Nov. 1, 1805. I arrived here yesterday where I intend staying until spring if not sooner honoured with your command. I have the honour to be, Sir, with the greatest respect, Your Obt. Serv't, Jon" Cowdery. Robert Smith, Esq. After Doctor Cowdery's return to the United States his fortunes are best followed by a perusal of letters which he wrote from time to time to the Navy Department or to relatives or friends. With him in captivity in Tripoli was a private of marines named William Ray, who also kept a journal. In July, 1807, Doctor Cow- dry, who evidently was on leave at his father's house in Tunbridge, Vt., received the following letter from Ray : Dear Sir: My volume is nearly complete and will be put to press in a very short time, but I should nevertheless be very thankful to receive the remainder of your journal, for I have already taken the liberty of extracting from that part of it which was published in the Hudson Balance; and have made some remarks on the extracts, which perhaps, from a view of the whole, I might be induced to alter, I should also be happy to receive from you any interesting remarks you may be pleased to make ; particularly information relative to the origin of the war. I have received both from General Eaton and the Secretary of the Navy, all the information in their power ; but they arc not explicit, as respects the true rise of hostilities between the United States and Tripoli. I wish, likewise, for a list of the United States vessels of war which were lying at Gibraltar when we first arrived there. What arrivals while we lay there, and what ships of war of the U. S. were lost at that place, for I have but an imperfect recollection. I enclose you two subscriptions which I would thank you to circulate and return to Mr. John Barber, Printer in Albany, within a couple of months, by which time it is expected the work will be nearly printed. As the time is short, I must beg you to forward the papers which you have been kind enough to promise me, with all possible expedition, to the Gentlemen above mentioned.

Albany, Feb., 1807. This book was to be published in Troy, New York, in 1808, but all efforts to find a copy have been in vain. Among letters found in " Officers Letters," Navy Department Library, are some which show Doctor Cowdery's resentment at his delayed promotion. In a letter written July 22, 1807, at Tunbridge, Vt (near Chelsea, Vt.), he acknowledges receipt of orders to New York, and makes request for the promotion, which the Secretary had assured him that he should have, upon the occasion of their last meeting.2 In another letter, written at New York on August 7, 1807, he reports his arrival from Vermont, and states that he has reported for duty to Commodore Eodgers, who has assigned him to duty as surgeon's mate under Doctor Marshall.' States that he expected a "higher station," as he has been for a long time the oldest in the list of surgeons' mates. Mentions that he has attended the medical lectures at Hanover * the last two winters, and has been recommended by Doctor Mitchell 6 and others to the Secretary for promotion. Doctor Mitchell was a teacher of rare attainments and wide knowl edge in both science and medicine. His name appears in several of Doctor Cowdery's letters. In this letter Doctor Cowdery declares his fondness for the Navy and for the gentlemen belonging to it and is anxious to be of service to the country in " the present critical situation," ° but protests against being continued as a surgeon's mate, when younger men are pro moted over him. He requests the rank which was promised him when he and Lieutenant Stuart waited upon the Secretary- in Balti more. 1This letter as well as those which follow are addressed to the Secretary of the Navy, R. Smith. • S. R. Marshall, surgeon's mate, 14 May, 1799; Surgeon. 16 January, 1800; died 20 May, 1828. 'Dartmouth College (at Hanover, N. H.) established a medical department In 1797. • Probably Dr. Samuel L. Mitchell of the Columbia College and the College of rhyslclane and Surgeons, N. Y., who may have given lectures at Hanover. • The Chesapeake-Leopard affair had occurred only two weeks previous. On June 22. 1807, the frigate Chesapeake, Capt. Charles Gordon, bearing the broad pennant of Com modore James Barron, got under way from Hampton Roads bound to the Mediterranean. A squadron of British ships of war bad been at anchor in Lynnhaven Bay for several months watching some French frigates that lay at Annapolis. As the Chesapeake stood down toward Cape Henry, one of the British vessels, the Leopard got up anchor and preceded the American frigate to sea by several miles. When both vessels were well off the land the BriUsh frigate approached the Chesapeake and hailed her, Informing Com modore Barron that she had dispatches for him. In a few minutes a boat from the Leopard came alongside the Chesapeake beating an order to search the vessel for deserters from the British ships. This Commodore Barron refused to permit, Btatlng that he knew of no such deserters on board. The BriUsh officer returned to the Leopard, and almost No. 1. 77 JONATHAN COWDERY, SURGEON IN U. S. NAVY. Navy Yard. New York, August 17, 1801. D'- Sib: On my return from captivity in Tripoli I did myself the honour of calling upon you and in addition to letters of recommendation sent to you by Dr. Mitchell, and commanders in the Navy, whom I had the honour of serving under as surgeon's mate, I delivered to you two letters of recommendation, one from Captain Bainbridge and one from Dr. Ridgely.1 late Surgeon of the Phila delphia. You read them with great satisfaction and applauded my conduct in the Navy. I then told you that I had served a number of years as surgeon's mate and now hoped you would grant me a higher station. Y'ou replied that I should be promoted when I should again be called into service. You have again called me into service, and I am on duty as surgeon's mate, which, under the circumstances, is very humiliating to me indeed, and I now beg you will send me a surgeon's commission, or, if you deem me inadequate to this, I beg you will send me a discharge from the service. Yours with esteem. Jo" Cowdery. Hon. K. Smith, Secretary of the Navy. Fortunately, the "discharge from the service " was never sent, and Doctor Cowdery was promoted to the rank of surgeon in the Navy on the 27th of November, 1807. He was ordered from New York to Norfolk. Va.. where he made his home until his death in 1852. On May 15. 1807, he bought some land of Israel Chase, in Tunbridge, Orange County, Vt., and it seems that he had left his son Isaac Newton in charge of his brother. Elihu. The following extracts are from letters written to his brother Elihu : Norfolk, Va., Jan. 26, 1808. Dear Brother. I had the pleasure of receiving two letters from you since be ing on this Station, one was dated Dec. 3. and the other Jan. 3, in which I am pleased to find that you and our Family enjoy Health. In your letter of Jan. 3d you mention that you fear that I would receive your letters with reluctance were it not for the Business you have in Charge for me. —This, my brother, is a need- legs fear. You may rest assured that I esteem you as I ought to do as my Brother, both by Nature and by Art. our former trifling disputes ought to be without warning the vessel fired an entire broadside at the Chesapeake, wounding Com modore Barron and his aid, who stood In the gangway. The gunfire was continued from 15 to 18 minutes, when Commodore Barron ordered the colors to be hauled down. The Chesapeake Immediately sent a boat to the Leopard to say that the ship waB at the disposal of the English captain, who then directed his officers to muster the American crew. Four men, claimed to be deserters from British vessels, were carried away, and the Chesapeake returned to Hampton Roads. The attack on the Chesapeake aroused public sentiment in the United States against Ureat Britain and almost led to an Immediate declaration of war. —Cooper, J.

He was surgeon on the Philadelphia, Jonathan Cowdery and Nicholas Harwood being the surgeons' mates. Dr. Ridgely was appointed charge d'affaires of the United States to the Regency of Tripoli in June, 1805. upon the recommendation of Commodore Rodgers. He resigned in 1808 and settled In Annapolis, Md. The practice of appointing medical officers to diplomatic posts In the Mediterranean was not unusual in these days. In addition to Dr. Rldgely's appointment to Tripoli, Commodore John Rodgers appointed Dr. James Dodge, surgeon of the Constitu tion, to act as charge1 d'affaires at Tunis, and Commodore Richard V.

They are of both sexes and are very Hospitable to the officers of the Navy and Army, who are here In abundance. We are invited to all of their public amusements, etc., etc. The British officers of the Frigate which brought Mr. Rose as a minister to our Government, come on shore occasionally, they visit but little except at the British Consular House (Col. Hamilton). We all treat them much cooler than they have been used in the American Ports. Lieut. John Davis, one of our officers who Commanded Gun Boat No. 1, put an end to his existence the other day, by discharging a pistol through his Brains while lying in his Bed in the Cabin of his Gun Boat. He had been disgraced for bad conduct, he was much given to Dissipation, he found that he was despised and neglected by all his Brother Officers, and was much in debt, which is supposed caused an insanity and was the reason of his committing the horrid deed of Suicide. I was called to him before he was dead, but could not help him. * * * The winter is very Pleasant, but the summer is to be dreaded by us northern people. (Signed) Jon° Cowdeey.

Dear Brother, I have the pleasure of again addressing you ; we lately re turned from a very tedious cruise on the coast of New England, we had almost constant gales of wind with much Snow and Rain. Many of our Crew* were much frozen. I had thirty on my list at one time, who were frost bitten in a greater or less degree. I have saved all their limbs and the most of them are again on Duty ; We are now taking in Provisions, Water, &c for an other cruise to the northward to enforce the Embargo Laws, and to prevent Insurrection in the forests of New England. The Embargo is an oppressive law, but as it is the choice of the majority of our Country, it is the duty of ua all to Support It, I have suffered much in the cause of my country, and I am willing yet to serve It at the hazard of my Property, my Health, my Comfort and if Necessary my life. But in Vermont I was called a Federal Tory by those who are now violating the Embargo by smuggling into Canada, and these very men voted for the Member in Congress from Vermont who voted in Congress for the passing of the Embargo Laws ; but I am happy to se* a change in your People. I see that you in Vermont as well as in all the New England States have a large majority of Federal Republicans for the next Congress. I hope that the liberty and Character of our Country will yet be saved. I saw Brother Austin's name in the proceedings of the Grand Lodge of Vermont, in the newspapers at Boston.

I am with much esteem Yor loving Brother, Jon* Cowdebt. His letters written during the year 1809 indicate that the state of his health was not the best. One dated Norfolk. June 7, 1809, acknowledges orders to the Xau- tilus and expresses regret for a delay until his health is sufficiently recovered to comply with it and join the ship before she is ready for sea, " during which time, if you may deem it proper and will be pleased to command me, I will attend to the procuring the necessary medicines, instruments, etc., which may be procured at this place on very reasonable terms." Another, dated Norfolk. July 14. 1809, and addressed to Hon. Paul Hamilton, Secretary of the Navy, acknowledges orders to the Ferret, but he reports himself ill, though better of the lameness which he mentioned to Mr. Goldsborough 10 when last in Washington. He has a complaint in the breast which is no better and is much emaci ated and debilitated. His infirmity originated from sufferings on board the Argua'the previous winter off the coast of New England, when he contracted a violent cold, since which he has not enjoyed a well day. " I have yet reason to hope it will not prove to be a con firmed decay. I am now in a course of medicine and diet under Drs. Barraud and Hansford, (both very eminent in their profession) which I hope in a few weeks will relieve nie sufficiently to join Lieut. Gadsden on the Ferret.

" The first medical journal published tn America was the Medical Repository, a quar terly, under the editorship of Samuel L. Mltchill, Edward Miller, and KHliu Smith. It was founded in 1797 and continued until 1824. 10Charles W. Goldsborough was for many years chief clerk of the Navy Department and the author of the uncompleted work, the United States Naval Chronicle. One volume only was published In 1824. Goldsborough's connection with the Navy Department con tinued over a period of 44 years. He was chief clerk under Secretaries Stoddert.

The doctor writes from Norfolk, under date of October 4, 1809, that he has spent 10 years in the Navy — 19 months of which he was in captivity in Tripoli. He has lost considerable property as a result, and also the vision of the right eye,12 and has suffered much impairment of health. He states that he has a wife and three chil dren to support, and asks if he can have duty at the navy yard at Gosport when Doctor Heerman leaves, the latter being not averse to a change of station. In a letter written on board the frigate United States on February 20, 1811, he reports joining this ship, in accordance with orders, and reporting to Commodore Decatur. He expresses the hope that the cruise will benefit his health, but requests permission to visit Wash ington on the return of the ship to Norfolk in order to settle his accounts at the Navy Department and obtain a furlough, during which he desires to make arrangements to provide for his family (a wife and four small children). In several letters written in 1808-9 and 1810, Doctor Cowdery speaks of having established a drug store in Norfolk, Va., and also mentions owning the Chase, Newhall, and Stanley places in Tun- bridge, Vt. The settlement of his affairs in Tunbridge seems to have been the cause of much perplexity, and some misunderstanding be tween him and his brother, and his brother-in-law, Samuel Austin. After much correspondence on the subject, Doctor Jonathan writes to his brother Elihu, on July 8, 1914. " I have written Mr. Paine, the attorney, to settle with you and Austin on amicable terms and not to put you to any cost or inconvenience if he possibly can avoid it. I had rather lose a thousand dollars than wrong either of you one cent. I therefore desire you and Austin will come to a settle ment with him of everything concerning me. I deprecate family disputes. I therefore hope you will settle everything amicably. I am on duty in the Navy on this Station. We have about 700 men in the service, and I have had the good fortune not to lose but one man since I had the medical charge of them, which is a year last spring. We hope for Peace soon, but are under apprehension that "In later years Horseley became surgeon ou the Lawrence with Commodore O. H. Perry, and was present In the Battle of Lake Erie on Sept. 10, 1813. "Conjnnctlvitla was very prevalent in Tripoli. 82 JONATHAN COWDERY, SURGEON IN U. S. NAVY. Vol. XVIL the war will last many years.

I beg you will not let them suffer, should they be in want I am ready and willing to contribute to their com fort and support." In a letter written on August, 1815, Dr. Cow- dery appoints " My honored Father Jabez Cowdery of Tunbridge, Vermong, my true and lawful attorney." Nothing appears in the files of the Navy Department's corre spondence concerning Doctor Cowdery until 11 years later, at which time we find him ordered to sea and apparently feeling the weight of his years and the disadvantages of ill health. In a letter written at Norfolk, on April 16, 1823, in reply to the Secretary's order of the 10th to join the Hornet, he states that ill health will prevent, that he is 56 years old on the 22d day of this month and in the Navy 23 years, and has made no complaints about orders until now. He asks to continue on the station and have his orders to sea revoked. He inclosed a letter from Surg. George J. Kernays which states, "that Doctor Cowdery for 12 months has feared that he was losing use of one leg and thigh. He requires care to prevent a termination in a general paralytic affection of the lower extremity." Indorsement by the Secretary of the Navy. " The order may be revoked, another must be obtained." From Norfolk, under date of January 9, 1824, he writes that he has been with Commodore Porter in former days and in trying scenes, but by reason of ill health he is not able now to render service to him and under his command " in the contemplated cruise against the enemies, not only of our country but of the human family." He wishes to have a position on the station (i. e. Norfolk) and states that he was " in all wars since the Revolution to the end of the last British war—out in the Argus and in the United States during the greater part of the embargo. In the Navy 24 years on the 1st of this month and 58 years old next April and been in sea service (I.believe) more than any surgeon in the Navy." He suggests that he may be useful at the recruiting service attending the sick and disabled officers and seamen not accommodated at the hospital and explains the he " is now attending some of this description and assisting the younger surgeons in making out their requisitions, etc., and in examining old or damaged articles of the Medical Department be longing to vessels after a cruise, and in attending sick seamen on Crany Island who may be quarantined, as I did the last two seasons." No. 1. JONATHAN COWDERY, SURGEON IN U. S. NAVY. 83 This letter bears the following indorsement by the Secretary of the Navy : " Countermand orders and leave him as he was before. 16 Jan. 24, Samuel L. Southard." 1S A letter from the U. S. R. S. Alert, dated April 19, 1827, indicates that Doctor Cowdery was still at Norfolk. When 63 years of age, Doctor Cowdery was ordered to sea as medical officer of the U. S. S. Warren and as he was to be the senior medical officer in the Mediterranean Fleet he was exceedingly anxious to secure the denomination as surgeon of the fleet and accordingly wrote the following letter to Andrew Jackson, the President of the United States: Navy Yard, New York, SO June 1829. Sib: I hereby take the liberty of addressing your Excellency on a subject which to me is of vast importance, and for which I have reason to believe you will have the goodness to excuse, and duly appreciate. I have belonged to the Navy of the United States as a Medical Officer nearly thirty years, have been on duty at sea and on shore stations the whole of this time, excepting about two years after being released from Tripoli cap tivity and I flatter myself to believe that I have performed my duty to the satisfaction of all whom I have the honor to serve. I lately received orders from the Honb" Secretary of the Navy to proceed to New York and report to Commodore Chauncey for a passage to the Mediterranean and then report to Commodore Crane for duty on the U. S. Ship of War Warren. I resolved to obey the orders as far as was in my power, and did myself the honor of calling on and taking leave of your Excellency, and also the Hon"* Secretary of the Navy. I then wanted to confer on the subject of my rank, but found your excellency so much engaged that I concluded It would be best to write you on the sub ject, and not delay the obedience of my order. The Act of Congress for the organization of the Medical Department of the Navy of the U. S. of 24th of May 1828, 2nd Section, authorizes the President of the U. S. to appoint to every fleet or squadron of the Navy a surgeon then in the naval service of the U. S. to be denominated Surgeon of the Fleet. Therefore if I am to be the oldest surgeon on the Mediterranean Station I do most respectfully ask your Excellency to grant me my rank. It would be humiliating to serve under a younger surgeon. From your Excellency's military renown and kindness of heart, you can duly appreciate the feelings of an officer on a subject of this nature. I hope I may not be allowed to leave my country, my friends, my wife and children, with a heavy heart. As for my naval, or professional character, I refer your excellency to Commodore Barron under whose command I last had the honor of serving on the Norfolk Station. "This letter Indicates that Doctor Cowdery hud been ordered to Commodore Porter's squadron, which had been operating in the West Indies against pirates, then infesting these waters. Commodore David Porter had resigned his position as Commissioner of the Navy to assume the command of this expedition. He took his squadron to sea on the Hth of February, 1823, and after successfully suppressing piracy about Cuba and Porto Eico, arrived at Thompsons Island (Key West) late in the year. Here yellow fever broke out in several ships and soon forced the sailing of the squadron to the northward. Porter's action during thla campaign in landing an armed force at Fajardo, on the island of Porto Rico, in an attempt to force an apology for harsh treatment of some of the officers and men, brought about his trial by court-martial and his suspension from duty for six months. 84 JONATHAN COWDERY, SURGEON IN U. S. NAVY. Vol. XVII I am to take passage to the Mediterranean in the U. S. Ship Ontario; she is to sail from this port ; it is likely that she will be detained several weeks for want of seamen, whom are slowly procured, therefore I hope to be honored with a reply to this communication before leaving this country. I am respectfully, Sir, Your Excellency's Obedient and very humble servant, Jon" Cowdebt, Surgeon. His Excellency, Andbew Jackson, President. (Indorsed by the President:) "Referred to the Secretary of the Navy for answer. A. J." The following letter, which was written to his son, Benjamin Franklin Cowdery, then ir Geneva, N. Y., gives some insight into Dr. Cowdery's character. New Yobk, Aug. 17, 1829. My Deab Son. It is a considerable time since I had the pleasure of hearing from you. As this may be the last time, I feel it a duty now to address you. I am about to leave my Dear Country, family and friends, on another cruise of perhaps three years in the Mediterranean. I was in hopes that my former services and age, would induce the Government to allow me a shore station the balance of my days. On my receiving orders for this service, while I was on duty as Surgeon of the Naval Station at Norfolk, in Virginia, and where my wife and four children now reside, I went to the city of Washington to see the President of the United States and the Secretary of the Navy on the subject of my being ordered to sea in my old days, they both urged the neces sity of my complying with the order and said that my services were particu larly required in the fleet as being an old and experienced surgeon. I concluded that it was my duty to obey the call and again go on foreign service for my country. I am to go out a passenger in the U. S. Ship of War Ontario; she is fitting out on this station. We expect to sail within two or three days for the Mediterranean to join our Squadron at Port Mahon, where I expect to be put on duty as fleet surgeon. The Delaware 74, Commander Crane, is to return to the U. S. Commander Riddle is to take command of the Squadron. A Mr. Lee, Consul General of Algiers, two or three Lieutenants, two young Gents who lately graduated at Yale College, and several Midship men are going as passengers in the ship. I have left my son G. W. Cowdery in charge of my family in Norfolk. He will be twenty one years of age next December ; he is a moral, steady, studious and promising youth. I place great confidence in him, and hope he will become a Christian and an ornament to his fellow mortals. My son, before closing this epistle I will say a few words on this important subject of Religion. I for several years have been under serious impression on this subject. I am convinced of the truths of Christian ity, as it is set forth in the Holy Scriptures. I hope that God has forgiven the many sins of my younger days, I feel a confidence in him and a thankfulness for his many and continued blessings bestowed on me and mine. I am a member of his Holy Church. I read his Word and pray for his Blessings and Salvation. What is this world without religion. .Toys at best are but transi tory, all checkered with afflictions, even if we live a hundred years, life is but a phantom in comparison to eternity, therefore is it not best to strive to serve God, with the hope of his benediction in this world, and the world to come. My love and best respects to your Dear Family, and that all of you may be con stant in serving God and our fellow mortals is the prayer of your affectionate father, Jon* Cowdebt. No. 1. JONATHAN COWDEBY, SURGEON IN U. S. NAVY. 85 Fourteen years pass. We assume that Doctor Cowdery finished his cruise in the Mediterranean and returned to duty at Norfolk, but detailed information relating to this period is lacking. He is now well along in years, but evidently not willing to be superseded by a younger man, as the following letter to the Secretary of the Navy indicates.

The Norfolk Beacon of that date in referring to him said : " Few men have borne a more unblemished character or been held in such high and universal esteem for all the qualities of head and heart that constitute the efficient officer and worthy citizen." He was buried in Cedar Grove Cemetery in Norfolk, in a lot with his wife Eliza, and his sons, Alexander, Augustus, and George Wash ington. His remains are in a small vault resting on the ground, the sides of which are granite and the top marble. One visiting his grave to-day may read the following inscription covering the marble slab of the vault : " In Memory of Jonathan Cowdery, Surgeon of the Navy of the United States He was born April 22, 1767, And died November 20, 1852. Affectionate in his nature, faithful in the performance of his duty, and pure in spirit, He has left, as a patriotic christian, a character without stain, and an example worthy of emulation. He was upwards of fifty-two years in the service of his Country, and at the time of his death held the oldest commission in the Navy."

It so happened that when one of us had decided that Doctor Cowdery had probably spent his last days in Norfolk, Doctor Leigh was addressed with a request that he indicate some one who might give information of the place of burial of Doctor Cowdery and supply biographical data relating to him.

Edwin Pitebhon, Medical Corps, United States Navy. AN INVESTIGATION OF THE ETIOLOGY OF EPIDEMIC ENCEPHALITIS. The causative agent of epidemic encephalitis (lethargic enceph alitis) has apparently been demonstrated by Strauss, Hirschfeld, and Loewe, working in the pathological laboratory of Mount Sinai Hos pital, New York City. Their work has been confirmed wholly or in part by others in France (1), England (2), and the United States (3). The investigation was exhaustive, conclusive, and all the steps were well controlled. The results were published in a series of arti cles entitled " Studies in epidemic encephalitis," appearing in various periodicals. The first of this series (4) describes results obtained by subdural or intraperitoneal inoculation of seven monkeys, with ma terial obtained from human cases or from artificially infected mon keys. A saline emulsion of brain tissue from a fatal human case pro duced lesions in a monkey similar to those of human cases. Wash ings from the nasopharynx of a human case were passed through a Berkefeld filter and injected subdurally and intraperitoneally into a monkey and produced a paresis of both hind legs and an increase in the spinal fluid cells. A similar filtrate, from the mucous mem brane of the nasopharynx of a fatal cardiac case, produced no appar ent lesions in the monkey up to the date of the presentation of the report. The next report (5) describes experiments with a group of rabbits and the further results on the first seven monkeys as well as several additional ones. Rabbits were injected intracranially with a Berke feld filtrate of nasopharyngeal material from a patient suffering from encephalitis, and others with material from control cases. At the same time, others were injected with material from rabbits dying from the induced infection. By this series of experiments the authors demonstrated that a filterable virus from the naso pharynx would produce lesions in rabbits and monkeys similar to those in the human brain, and that this virus could be recovered 89 90 Vol. XVII EDITORIAL. from the nasopharynx of animals which had been previously in oculated intracranially. Approximately 50 per cent of rabbits seemed to have a natural immunity. One infected monkey that recovered was found to have developed an immunity. Up to this time attempts at culture, using the ordinary aerobic and anaerobic methods, were unsuccessful. Another paper (6) describes the successful cultivation by the method employed by Noguchi (7) of an organism resembling in appearance of colonies, of growth, and of morphology the organism described by Flexner and Noguchi in poliomyelitis (8). Details of the method of culturing and of appearance of the organism are given more fully in a separate report (9). The media used consisted of sterile kidney fragments covered with 3 or 4 cubic centimeters of sterile ascitic fluid in test tubes of 20 by 1.5 centimeters, and which was incubated for 48 hours. Contaminated tubes were discarded when contamination was detected by gross examination or by dark- field illumination of smears. Better results were obtained when an old ascitic fluid was used. This should be bile-free and of high specific gravity; the presence of fibrin helps the growth of the or ganism. The best material was that obtained from decompensating cardiac cases. The tubes were first inoculated and then ascitic fluid was added to make a column 10 centimeters high. Petrolatum of low melting point was added to make a layer of 1 centimeter in thickness. Alboline may be used, but with this a Novy jar is necessary. As control tubes they employed combinations of ascitic fluid with petrolatum; inoculum, ascitio fluid, and petrolatum; ascitic fluid, kidney tissue, and petrolatum. As inoculum they used brain fragments, spinal fluid, blood, and nasopharyngeal wash ings. The tubes were inoculated at 37° C. ' In no instance did the organism grow on solid media from in fectious material, and only grew on solid media on subculture. A successful growth appeared by the fifth to the seventh day as a clouding of the media about the kidney tissue. The optimal solid media was of gelatinous consistency, made so by the addition of one part of 2 per cent nutrient agar to four or five parts of ascitic fluid with kidney tissue. The organism appeared in solid media as minute colonies, more numerous near the kidney tissue. All con trols were negative in both solid and fluid media. The organisms were fixed in methyl alcohol and stained with Giemsa's or Loeffler's alkaline-methylene blue for one or two hours. They appeared as small globular or spherical bodies stained purple or blue and ar ranged singly, in pairs, chains or clumps. The organism lived in culture media for at least six weeks and in the older cultures showed larger degenerated forms. The organism was nonmotile. Gram staining varied with age and with the culture media ; young cultures No. 1. 91 EDITORIAL. on solid media were mostly gram positive. Morphologically, it is like the organism of poliomyelitis of Flexner and Noguchi, but it differs from the latter in its action in animals, particularly in the suscepti bility of rabbits to this organism. The virus was carried through 12 generations on culture media, and the seventh and eighth were still fatal for animals. The organism was obtained from the fol lowing locations : 1. Berkefeld nitrate of extract of nasal mucosa, 7 of 10 cases. 2. From the washings of the nasopharynx, 15 of 23 cases (66 per cent of the human cases). 3. Spinal fluid in 12 of 24 cases (8 negatives from other diseases)'. 4. Babbit nasal mucosa in 3 cases.1 5. Babbit brain, 36 of 56 positive, (64 per cent).1 6. Monkey brain, 5 of 6 cases.1 7. Human brain, positive in a few rapidly fatal cases observed. 8. Human blood, positive in 2 cases tried. Babbits were readily inoculated while monkeys were relatively refractive —the reverse of poliomyelitis. The spinal fluid of poliomyelitis patients is innocuous to rabbits or monkeys, while encephalitis is produced in animals by injection of spinal fluid from positive cases. Successful inoculations of monkeys and rabbits having demon strated the presence of the virus of epidemic encephalitis in the nasopharynx and in the spinal fluid of patients with the disease, it was suggested (10) that this be employed as a means of making a differential diagnosis. They used nasal washings or material ob tained on a swab from the nasopharynx, which was emulsified in saline, passed through a Berkefeld filter and inoculated intra- cranially. Spinal fluid was used for inoculation, in quantities of 0.5 c. c. or less. An inoculation with Berkefeld filtrates of naso pharyngeal material produced characteristic lesions of epidemic encephalitis in rabbits in 78 per cent of cases tested. A small coccoid body was recovered from cultures of filtered nasopharyngeal wash ings in 11 of the 17 cases (64 per cent). The spinal fluid from 12 of the 16 patients, or 75 per cent, when inoculated into rabbits intra- cranially produced characteristic lesions. Cultures of spinal fluid were positive in 10 of the 20 cases (50 per cent). The positive results with spinal fluid sharply differentiate encephalitis lethargica from poliomyelitis. Numerous controls were entirely negative. In France, Levaditi (1) and Harvier (11) found a virus fatal to rabbits in four to six days in many cases of epidemic encephalitis. A Berkefeld filtrate of the virus from human cases was nonpatho genic to monkeys, but became pathogenic after passing through 'These animals were Inoculated cases. 103390—22 7 92 Vol. XVII EDITORIAL. several rabbits. It could also be preserved in glycerine. A crossed immunity between poliomyelitis and epidemic encephalitis could not be induced. The serum of a convalescent from one disease had no effect on patients suffering with the other. Their cultural experi ments were negative, but they did not employ the technique of Noguchi. In England, Mcintosh and Turnbull (2) injected subdurally into monkeys an emulsion of the central nervous system from a patient who died of lethargic encephalitis, as well as a Berkefeld filtrate of this emulsion; both animals showed characteristic lesions of the disease. No attempts were made to culture. In the United States, Thalhimer (3) has confirmed the findings of the Mount Sinai Hospital Laboratory, using material from four cases of the disease—two of the fulminating type, one with marked myoclonus, one with marked lethargy. A Mandler filtrate of the central nervous system of all four cases was used as a source of ma terial as well as the spinal fluid of one fulminating and one con valescent lethargic case, with fading symptoms. He used about two hundred rabbits, giving intracranial injections through the temporal plate, and found that they withstood the injection of 1 c c. very well. Infected animals showed varying symptomatology. A few died of intracranial hemorrhage. Most of them died in from 2 to 4 weeks and some as late as 10 weeks. Material in each in stance was inoculated into groups of from three to eight rabbits. Some groups showed 100 per cent mortality, while others as low as 50 per cent. Two strains of the virus have been passed through a Mandler filter and reinoculated into six groups of rabbits. The lesions in the nervous system produced by the disease are scattered, and extensive study is necessary or they will be missed in many cases. Several series of controls were negative. In the cultural work, Thalhimer (3) used Noguchi's media and method. Spinal fluid was inoculated directly, while an emulsion of central nervous system was passed through a Mandler filter and the filtrate inoculated. Growth appeared in 5 to 10 days, and was similar to that described by Loewc and Strauss. Cultures were ob tained from the brains of the four cases studied, and from the two spinal fluids. Some cultures were carried to their sixth successful subculture. Cultures were recovered from about 84 per cent of the brains of the animals successfully inoculated. A positive culture from a rabbit's brain from the sixth series or generation was ob tained. All subcultures were made from a Mandler filtrate of posi tive cultures. Original material and cultures inoculated on ordi nary media and Rosenow's ascitic fluid glucose agar were all nega tive except for occasional contamination. Control cultures from tlie No. 1. 93 EDITORIAL,. spinal fluid obtained from patients with other diseases were all negative. In summing up his work the author stated that infectious agents were apparently constantly associated with epidemic encephalitis. The infectious agent passed a Mandler filter and produced a disease in rabbits very similar to that in man. The original dose of virus was passed through six animals, and if it were not a reproducing virus it would be so well diluted that it could hardly be held re sponsible for the lesions produced. On Noguchi's media he culti vated an organism like that of Loewe and Strauss. The organism was recovered from 80 per cent of inoculated cases and from animals inoculated from cultures. (Loewe and Strauss produced the disease in animals with the eleventh generation of the organism.) Loewe and Strauss diluted a filtered virus through six diluting tubes, putting 0.2 cubic centimeter into 15 cubic centimeters of ascitic fluid in each instance, and demonstrated that the virus was so diluted as to be innocuous in the sixth tube, thus proving that the virus must proliferate in animals in order to continue producing the disease. Amoss (12) confirmed the absence of crossed immunity by con trolled experimental inoculation of monkeys, showing that serum from epidemic encephalitis cases would not protect against polio myelitis virus. Other workers have reported several other organisms recovered from the blood stream or the brain of cases of epidemic encephalitis, but all from limited groups of cases. The organisms varied as to type, source, and pathogenicity for animals. The latter investiga tions were not sufficiently thorough and complete to be conclusive and may very well be disregarded, whereas the work at Mount Sinai Hospital was very thorough and conclusive. Koch's postulates were fulfilled and at the present writing it would seem that we have a definite causative organism for epidemic encephalitis. BIBLIOGRAPHY.

In an experience of about 16 years of hospital service (civil and naval, ashore and afloat), the writer has often been impressed with the fact that, except as concerns patients on " special diet," all food is consumed during a period of about 10} hours in each day. This is partly due to custom and partly to practical considerations relating to employees, but it does not seem to be the best possible arrangement as regards those who are being fed. Especially is it unsatisfactory where it is desired to build up men whose physical condition is impaired from any cause, and this includes a large pro portion of all hospital patients—postoperative cases, and convales cents from acute infections of whom only a fraction are usually carried on the " special " list, for " 8 o'clock nourishment." For about two months an experiment has been tried at a certain naval hospital, which is felt to have given such successful results as to merit report and which it may be desired to try elsewhere. Each day a large kettle of soup is prepared in the main kitchen. After supper it is transferred to the ward kitchen, in charge of the ward supervisor, and during the early evening is reheated on the gas range. Later in the evening the soup is served in Navy bowls, with bread (no butter) to all applicants—patients, Hospital Corps men, and those employees who are subsisted at the hospital. The only restriction on its issue is that the supervisor on watch shall see that a sufficient quantity is reserved for the night force coming on duty at 9 p. m., and it is allowed to be taken to the bedside or the ward table or to be eaten in the ward kitchen. The cooks are given wide latitude but are instructed to vary the kind of soup as much as may be done conveniently. The main points to be observed are that it shall be nutritious, ample in quantity, appetizing, and economical. A " stock pot " is kept constantly in use and receives all suitable bones, meat trimmings, and other proper ingredients. If soup has No. 1. 95 EDITORIAL. been served at dinner any residue that may be left is utilized. All available " odds and ends " and " left-overs " find their way into the soup kettle, and a very large proportion of these would otherwise go to the garbage can as the quantity is not sufficient to serve to a mess and it is not practicable to serve any article to a few persons only. This utilizes any small surplus of materials remaining in the ice box or in the serving dishes such as cold beans, peas, potatoes, tomatoes, macaroni, bits of asparagus, carrots, turnips, cabbage, and oatmeal. Occasionally a plain bean or pea soup is served, or a regularly made " cream of celery " or potato soup but, in general, it is an " olla podrida " and best liked when it has " lots of vege tables." I believe that the serving of soup in this way not only utilizes materials which would otherwise be wasted but that the absorption of calories and other food values contained in the evening issue reduces the amount consumed at other meals by more than enough to offset the cost of the bread served with it; therefore I think it may be said that the cost is nothing, the satisfaction immense. One evening, an ex-patient, "who was visiting a friend in the hospital, was asked, " Did you come up to have a bowl of soup with us?" and his reply was " No-o, I came to see X, but I surely will mm that soup." I feel that this serving of soup and bread may also have some effect in the direction of reducing the desire to "go ashore" in the evening, which makes for the men's good in other ways besides re ducing their expenditures in restaurants. It is possible that in larger hospitals difficulties would be encountered, but it is also pos sible that they might be surmounted. If there is a "night cook" regularly on duty, as was the case at one hospital under my com mand, the necessary service and care of utensils is easily arranged. Why should this idea not be given a try out, not only in other hos pitals but at receiving ships and barracks and even on board cruising ships? A steaming cauldron of soup, one man in the galley, a row of serving pots, each supplied with a ladle and kept filled, a pile of cut "chunks'7 of bread, and a bowl and spoon for each man who wishes to come and "help himself" at any time from 8 o'clock to taps," would not be impossible nor even difficult, and the soothing sensation of repletion following a " night cap " of bread and hot soup would add luxury to the swaying hammock and prove a real asset of welfare, comfort, and contentment, to be looked forward to by tiie men as an agreeable break in the long evenings on board ship. I'erhaps even the officer of the deck would find not disagreeable the Performance of his duty in " inspecting " this issue of food. (m. f. o.) 96 Vol. XVII EDITORIAL. ON ACUTE APPENDICITIS. In the Annual Report of the Surgeon General of the Navy for the fiscal year 1921, we find that 1,038 patients were admitted to the sick list during the period covered by this report with a diagnosis of acute appendicitis. Of this number, 861 came to operation, and of these 16 died. The causes of death were ascribed in 1 case to carcinoma, in 1 to ether poisoning, in 1 to pneumonia, and in 13 to peritonitis — truly a satisfactory showing for the naval operating surgeon; yet might not the 13 deaths from peritonitis have been reduced in number or avoided altogether by perhaps an earlier diagnosis or an operation in the early stage of the disease? The mortality from acute appendicitis is practically nil in cases which are operated upon early in the disease; the mortality is high in cases operated upon late. After the infection has invaded the peritoneum and resulted in peritonitis, either localized or general, the disease becomes a serious affair. If the diagnosis can be made within the first 12 hours after the onset of the symptoms, a prompt operation, with removal of the appendix and closure of the incision without drainage, will usually result in a prompt recovery. If, however, operation has been delayed until peritonitis has set in, the peritoneum must be drained, and the patient has not only to combat the effect of the operation but must also overcome the peritonitis. Often he is unable to do this and dies, when he might have been saved by earlier diagnosis or earlier operation. Three wrong principles of so-called medical treatment of acute appendicitis are partly responsible either for the errors in diagnosis or the hastening of necrosis of the tissues of the inflamed appendix. The first is the administration of morphine to relieve the initial pain before any diagnosis has been made. Before giving any nar cotic to a patient with belly pains every effort should be made to establish the diagnosis, for as soon as a patient is under the influence of morphine the symptoms are masked. Spasm and rigidity, two very important signs in appendicitis, disappear; the patient feels better and when seen later in the day it is often impossible to make a diagnosis. The second error in the treatment of abdominal pain of unknown origin is the administration of cathartics, usually castor oil, calomel, or salts. Any one of these excites a violent peristalsis and if ap pendicitis is present, not only tends to spread the infection over the adjacent peritoneum, but often induces a perforation. The third error is the indiscriminate use of the ice bag. Capt. A. M. Fauntleroy. Medical Corps, United States Navy, writing in the Medical Record of August 3. 1912, calls attention to a series of cases of acute appendicitis coming to operation on the U. S. S. Solace. In No. 1. 97 EDITORIAL,. 60 per cent of these cases the appendix was gangrenous, about to per forate or pus was present. The health records of this series showed that an ice bag had been applied in 50 per cent of the cases. Fauntle- roy observed that when the ice bag was used there was a noticeable lack of effort on the part of nature to wall off from the rest of the ab dominal cavity the appendix, which was frequently very much con gested, gangrenous, or perforated. Every medical officer knows the symptoms of acute appendicitis, yet when we stop to think of the seriousness of the disease, a review of the symptoms may not be out of order. In a typical case of appendicitis the symptoms are somewhat as follows : The onset of the disease is generally ushered in with severe abdominal pain which extends over the whole abdomen. However, the first pain may be referred to the epigastrium, or it may be In the appendix region. The pain is usually followed by nausea and vomiting. In a few hours the pain localizes in the right iliac fossa and the patient is exquisitely tender at McBurney's point. The tem perature is usually elevated, but it may be normal. The pulse is usually accelerated and there is pronounced rigidity or spasm over the right rectus muscle. Constipation is usually present, but occasionally there is diarrhea. Symptoms referable to the bladder may be present when the appendix is long and hangs over the brim of the pelvis. The pain and tenderness are usually re ferred to the left iliac fossa or they may be referred high up on the right side when the appendix is retro-cecal. Examination of the blood at this time will usually show a marked leucocytosis and an increased percentage of the polynuclear cells. A low leucocyte count may indicate a lack of reaction on the part of the patient with a consequent poor prognosis. The severest types of appendictis may present the mildest symp toms. The writer has operated on cases presenting few symptoms in which the appendix was found full of pus and ready to rupture. In considering a diagnosis of acute appendicitis one should not neglect to examine the patient's general physical condition. Often the pain of a pneumonia on the right side is referred to the region of the appendix. The symptoms and signs of acute appendictis are usually clear and onmistakable. As soon as the diagnosis is established, the appendix should be removed at once. The treatment of acute appendicitis is surgical, not medical. During the first 12 or 18 hours following the onset of the disease, the abdomen can usually be closed without drain age and the patient will make a prompt recovery. When the peri toneum, however, becomes involved, drainage must be employed, and if the patient recovers, convalescence is prolonged and often stormy, (w. M. k.) 98 Vol. XVII EDITORIAL. ON THE USE OF IODINE AS A SKIN DISINFECTANT. The use of tincture of iodine as a disinfectant for the skin, par ticularly for the field of operation, and for the treatment of in juries, came prominently before the medical profession about 1905 and has been used extensively since that time. It was found that a 3 or 3| per cent alcoholic solution gave the best results. The use of a solution of this strength accomplished sterilization in a few minutes. Furthermore, it was found that if a healing wound was subjected to slight irritation by iodine a much smaller scar would be left than if it was allowed to heal normally. An excellent resume of the development of the use of iodine up to the latter part of 1910 by J. F. Wollheim appeared in the Ameri can Journal of Surgery for November, 1910. Little or nothing has been written on this subject since 1912 or 1914, so to get some expression of the present uses of iodine, particularly in industrial work, inquiries were sent by Dr. F. L. Rector, who writes on "Iodine as a wound disinfectant," in the Nation's Health for Jan uary 15, 1922, to about 75 physicians asking what preliminary cleansing was done to wounds and what strength iodine was used. Replies were received from 65 physicians, all of whom were doing industrial work or surgery closely allied to industry. Of this num ber, 2 use 10 per cent solution, 18 use U. S. P. 7 per cent tincture, 21 use 3| per cent, 10 use 3 per cent, and 3 use 2 per cent solutions. The other 11 physicians reported use of solutions of 4 per cent to 5 per cent strength. It is thus seen that a majority use a solution of 5 per cent strength or less. A few of the men said they did not use iodine. One preferred camphophenol, others used dichloramine-T, chlorazene, Dakin's solu tion, 7 per cent sodium oleate, picric acid, 5 per cent liquor cresolis compositus, 10 per cent calendula for large lacerated wounds, alcohol, bichloride of mercury 1 : 2,000 in 95 per cent alcohol, to which 2 per cent hydrochloric acid has been added. Several of the physicians emphasized the importance of having the surface perfectly dry before iodine is applied. A damp surface interferes with the penetration of the antiseptic. Earlier writers laid stress upon this point. The most satisfactory method of pre paring the wound area for iodine is to use alcohol and ether as final cleansing agents. For the preliminary treatment of wounds gasoline alone or in con junction with benzine or ether was used by 23 physicians. With 4 men soap and water was the agent of choice with the addition of gasoline or benzine if grease was present. Tincture of green soap was preferred by 6 men. From the replies received by Doctor Rector it would seem that the use of iodine as a skin and wound disinfectant still holds first place in No. 1. 99 EDITORIAL. surgical technic in the industrial field, in spite of the great popu larity attained by the chlorin compounds in the treatment of war wounds. Such objections as were raised were against the danger of burns and the discomfort iodine caused rather than against its efficiency as a sterilizing agent. The Conference Board of Physi cians in Industry has since its organization recommended the use of a 3 to 3£ per cent solution of iodine, and in the light of present experience feels that this recommendation is justified, (w. m. k.) ON THE REMOVAL OF FOREIGN BODIES FROM THE EYE. In discussing the removal of foreign bodies from the eye, H. D. Bruns, writing in the New Orleans Medical and Surgical Journal for February, 1922, points out the value of a good hand magnet, not with the idea of extracting magnetizable foreign bodies from within the eyeball, but for the purpose of pulling out those stuck in the con junctiva. There is probably no small operation more embarrassing than the removal of a nonmagnetic splinter which has penetrated the cornea. If the point of such a splinter enters, or almost enters the anterior chamber, the accepted practice is to pass a keratome through the margin of the cornea while the eyeball is steadied with a fixation forceps. The point of the keratome is held against the penetrating end of the splinter to prevent its being driven in further as the operator grasps it with fine forceps. If the splinter has penetrated the iris and lens as well as the cornea an incision must be made embracing the point of entrance of the splinter. With a Graefe knife the cornea is transfixed a few millimeters from the wound, the knife is passed across the anterior chamber, and brought out at a point about the same distance on the other side of the point of pene tration. By cutting outward the incision is completed. The end of the splinter lies free in the incision and can be grasped and the object removed. If prolapse of the iris occurs iridectomy is indi cated. Metallic splinters may often be removed by a good hand magnet, especially if they have only penetrated the superficial layers of the cornea. Foreign bodies on the cornea which are not magnetizable must be removed by some instrument under cocaine anesthesia. The writer prefers a probe with a 4ittle cotton tightly twisted about its end. Standing behind the patient, who sits facing the source of light, the operator holds the lids with the thumbs and forefinger of one hand. Having located the foreign body, with a quick motion of the fingers he makes the cotton-wrapped tip of the probe describe a short curve from above downward, which strikes the body at the height of its convexity at the point where the curve is tangent to the cornea. This 100 Vol. XVII. EDITORIAL. should be done lightly at first and then with more force until he is convinced that the body can not be removed in this way. If one is successful, the foreign body should be found sticking to the cotton on the probe or in the lower conjuctival cul-de-sac where it has been knocked. If the body is not removed by this manipulation, one must resort to the use of a dull-edged spud, flat on one side, rounded on the other and with no point, using it as he used the cotton-tipped probe. Failing in this, the end of the spud should be placed above and against the foreign body, and with a quick downward and out ward flip an attempt is made to turn it out of its bed. If this fails, the point of an old Graefe knife or a flattened discission needle in serted behind the body may dislodge it. Foreign bodies either on or in the conjunctiva are easily removed after eversion of the lid. In all manipulations about the eye the greatest surgical cleanliness is necessary. Instruments and dressings should be sterile. The method of cleaning an eye in use in a New Orleans clinic consists of repeated instillations of fresh 10 per cent solution of argyrol as repeatedly washed out with sterile normal salt solution or freshly made borax—boracic-camphor water. Fresh argyrol, in freshly made solution of a strength not greater than 15 per cent, used not longer than two weeks at a time, does not irritate the eye. The diffusibility of argyrol is pronounced; it penetrates everywhere; it dislodges old secretions from the lachrymal sac and thoroughly cleans the conjunctival sac. After a foreign body has been removed and the eye thoroughly cleaned it should be occluded by a sterile dressing, which should be renewed every day after cleansing the eye until all abrasions are healed. If the abrasion is small and the patient cleanly and intel ligent, argyrol solution may be instilled every hour until redness and the rough sensation on winking have disappeared. Bathing the closed eye frequently with hot water favors this and gives comfort. The Berger binocular loup and its accessory condensing lens, together with the 5 per cent solution of fluorescine, are very useful in locating foreign bodies. The binocular magnifier greatly increases the information we derive from the examination of any small lesion, and the fluorescine solution, after it has been instilled for three or four minutes and then washed out, reveals the tiniest body by sur rounding it with a bright green ring; or if the foreign body has been swept away by the tears, the abrasion caused by it is shown by a small spot of an intense green color. If the search is not successful in the daylight, it must be continued in a dark room with the aid of artificial light. Indeed the search for a foreign body must never be abandoned until one has made use of oblique artificial light in a dark room. (w. m. k.) No. J, 101 EDITORIAL. ON KALA AZAB. With the exception of the discovery of the specific action of tartar emetic in the treatment of kala azar, Wenyon finds, in reviewing the recent literature on this disease in Tropical Diseases Bulletin for February, 1922, that very little has been added during the last 10 years to our knowledge of this infection. In addition to the well- known endemic centers in North China, India (particularly Assam), the Caspian region, Mediterranean littoral, and the Anglo-Egyptian Sudan, new foci have also been discovered in Mesopotamia, Sumatra, and Siam and in the districts around Lake Chad (Africa). The role of animals in spreading kala azar has not been determined ; in several regions, notably the Mediterranean littoral and the Cas pian region, canine kala azar occurs as does the human disease, whereas in other regions only one of the two has been demonstrated. Even if it is admitted that the two types are caused by the same organism, Wenyon does not believe that the dog plays any essential role in the spread of the human disease. The diagnosis of kala azar depends upon the discovery of the para site, and spleen puncture still remains the most reliable and rapid means of attaining this object. The organism is frequently discovered by direct examination of the peripheral blood, where it generally appears in the mononuclear leuco cytes, although it may occur in other cells. Painstaking search is often required before the parasite is found by this procedure. Blood culture on NNN medium has yielded very good results in the hands of some observers. There is a certain disadvantage in using this method, however, because the number of parasites inoculated in the medium is so small that often two or three weeks must elapse before flagellates are detectable. It should always be done, however, espe cially in cases in which spleen puncture is contraindicated. The prevalent idea that the Mediterranean type of the disease attacks only children and the Indian type only adults must be dis carded in view of more recent and careful observations. Mackie, Muir, and Knowles in India, Cochran and Wylie in China, and vari ous observers in the Mediterranean littoral have shown that the respective " types " may attack all ages, thus removing the mark of distinction between the two forms. The greatest advance has been made in the treatment of the dis ease. Since Caspar Vianna in 1913 first treated American cutaneous leishmaniasis with such remarkably good results, the specific action of tartar emetic has been confirmed both in Italy (Doctors Christina and Caronia) and in India (Bogers, Muir, Knowles, etc.), in the general infections occurring in these countries. 102 Vol. XVII EDITORIAL Attention has been drawn several times to the toxic effects of this drug. It was realized that great care had to be exercised in admin istering the drug, and that it was necessary to commence with small doses and gradually to increase them. Deaths have been reported in a few instances. Long-continued treatment is essential to bring about cure and to prevent relapses. Muir states that injections should be given every second day till fever has been absent for a month and then once a week for two to four months. Unless these weekly injections are continued relapses may occur. Knowles, in Shillong, has presented some very interesting facts regarding the effect of treatment. The immediate result is the rapid disappearance of the parasites from the peripheral blood, later followed by disappearance from the spleen and finally by cessation of the fever. The body weight increases, while the spleen decreases in size and a normal blood pressure is restored. Knowles recommends that the potassium salt (the "heavy powder" and not the "light powder") be used. He employs a 1 per cent solution in normal saline, autoclaved at 110° C. for 10 minutes and kept in a rubber-capped flask. If there is the least trace of deposit or opalescence in the solution it is discarded as not being safe to«use. The initial intravenous dose is 3 to 4 cubic centimeters for an adult. Injections are given on alternate days, the dose being gradually increased until 10 to 12 cubic centimeters are given toward the end of treatment. The intervals between the doses should be increased as there is some evidence of accumulative action. The standard course at Shillong is a course of 200 cubic centimeters distributed over a period of two and a half to three months. The injections should not be given within two hours of a meal. The sudden appearance of edema should be a danger signal. Other antimony compounds have been introduced for the treatment of kala azar, notably stibacetin and colloid antimony sulphide. Rogers treated 10 cases with the latter preparation and regards it as a dis tinct improvement over the soluble antimony tartrates in the treat ment of kala azar. The problem of transmission is still unsolved. Attempts have been made to inculpate many insects, especially the flea and bedbug. As yet, however, no satisfactory evidence has been forthcoming to sub stantiate claims made. In a telegram published in the Indian Journal of Medical Re search, January, 1922, Mrs. Adie states that she has found a swarm ing infection of Leishman-Donovan bodies in the salivary glands and ducts of Cimex rotundatus caught in the bed of a suspected kala azar case, and that this discovery positively proves that the bedbug is capable of transmitting the disease through biting. In No. 1. 103 EDITORIAL. a letter to the editor of the Lancet, published February 25, 1922, C. M. Wenyon discusses this announcement of Mrs. Adie's and in a well-arranged argument shows that in spite of her discovery con vincing evidence is still needed to prove that the bedbug is the vector of kala azar. Some of Wenyon's points are: Numerous previous experiments on the bedbug, apparently successful, have been shown not to be conclusive when the results have been critically analyzed. In Mrs. Adie's case it is evident that the bug came from a bed, not of a case of kala azar but only a suspected case, and there is no proof that the bug had even fed on this particular individual. Proof is also needed that the parasites found are Leishman-Donovan bodies. It is possible that the bedbug may occasionally harbor a flagellate of its own, although this has never been shown before. Prophylaxis as carried on in India to-day is based on the ap parent fact that kala azar is a house and family disease. Segrega tion of all families having the disease is attempted, especially in Assam. That the newly introduced treatment by tartar emetic will undoubtedly play an important role in facilitating the eradication of this disease is pointed at by McCombie Young, (e. p.) IN MEMORIAM. XXSDLSTOH SEMMES QUEST. 1869-1922. Surg. Middleton Semmes Guest, United States Navy (retired), died at the United States Naval Hospital, Annapolis, Mel., on Janu ary 7, 1922, following a protracted illness. Surviving him are his widow, the daughter of Athanase Branchand, K. C, of Montreal, and one daughter, Ann Branchand Guest. Doctor Guest was born on May 23, 1869, at the navy yard, Ports mouth, N. H. He was the son of Commodore John Guest, United States Navy, who died in 1878 while commandant of that yard, and of Anna Josephine Pleasonton, daughter of Gen. Augustus Pleason- ton, of Philadelphia, and niece of Gen. Alfred Pleasonton, United States Army. He chose medicine as his profession, graduated from the Uni versity of Pennsylvania and, drawn by his associations, and the love for the service which remained such a prominent characteristic throughout his life, he entered the Navy as assistant surgeon in 1891. His professional career was marked by evidence of his conscien tious devotion to the details of duty, and a nice sense of discrimina tion in estimating the value of the rapidly succeeding advances in the theory and practice of medicine. Unfortunately, Doctor Guest was not given to writing for publication and consequently relatively few realized the shrewd, sane judgment he habitually displayed in matters of medical practice and administration. He exhibited similar reticence in his personal intercourse, and only intimates knew what an acutely observing mind functioned actively beneath his usually reserved exterior. His fund of remi niscence was a source of unending enjoyment to his friends, light ened as it was by a wit that was keen and penetrating, and yet always kindly. As is common with men of a retiring disposition, he found his recreation in the active pursuits of fishing, gunning, and the sailing of small craft. Of these amusements he never tired, and on occa sions when the actual sports were impossible he passed much of his leisure in studying the natural history of game birds and fish. He 105 106 Vol. XVII. MIDDLETON SEMMES GUEST. took great pride in his strength and endurance, so that the misfortune of prolonged invalidism was hard for him to understand and doubly hard to bear. Doctor Guest possessed an ardent love for the service, its customs, traditions, and even the minor features of a ship's routine. This de votion to the Navy was so absorbing that his retirement in 1910 came to him as a' great shock, the separation from the service entailed quite overshadowing in his mind the personal significance of his dis ability ; and when the United States entered the recent war, against the advice of those near him, he earnestly requested active duty. It was given him, but he could not carry on for long. The disease for which he was retired became active, and it proved necessary again to place him in an inactive status. In reference to this, he wrote in a private letter, " This is a villainous blow and upsets my hopes and plans completely. I hoped to have kept on until the close of the war and at least to have released some younger man for sea duty * * *, but it seems that my desire was greater than my strength to perform * * *." Comment would add nothing to these characteristic phrases. Liv ing comfortably, his disease quiescent, and urged by all his advisers to remain inactive, he could not tolerate the idea of taking no part in the struggle going on. Although, when the end was approaching, he realized clearly that his war duty had activated the disease, he had no regrets. By no other course could he have remained at peace with himself. REPORTS. A EEPOET OF THE HOSPITALIZATION7 OF THE VETEEAN AT OEEAT LAKES. By H. O. Datis, Lieutenant Commander, Medical Corps, United States Nary. The hospitalization of the veteran of the late war has become an important function of our naval hospitals and we are constantly seek ing the best method to efficiently administer to his needs and expedite the treatment that will make possible his complete vocational re habilitation. The usual hospital routine in professional, administrative, and clerical procedures becomes widely varied when an institution is handling and treating a class of patients largely unacquainted with naval customs. The veterans admitted to the naval hospital at Great Lakes, 111., differ greatly in mentality, temperament, and in their general attitude toward any form of treatment due probably to their experience in other hospitals or to seemingly unsatisfactory compen sation adjustments. The admission of ex-service men began in a small way early in 1921, when 50 beds were allotted to patients of the Bureau of War Risk Insurance. Those admitted were distributed among the Navy patients with no specific supervision other than general hospital care, and as there were no very definite regulations for handling them there soon arose petty disputes over working details in general. As the Navy patients decreased more beds were assigned to the War Risk patients, and it was deemed advisable to establish a special office apart from the main hospital offices in which business in connection with these patients could be carried out. A medical officer was placed in charge of this office. His specific duties are to admit all patients, ex plain the plan of treatment and something of the hospital, administra tion. He is concerned with all matters relative to ex-service patients during their stay in the hospital. After the passage of the Sweet bill, September 9, 1921, the Vet erans' Bureau was established, replacing the Bureaus of War Risk and Vocational Rehabilitation. By Executive order that portion of the naval: hospital at Great Lakes known as Camp Ross, was turned over to the Veterans' Bureau for the care of 300 neuro- 103390—22 8 107 108 HOSPITALIZATION OF THE VETERAN AT GREAT LAKES. Vol. XVII. psychiatric cases under naval administration. The bed capacity of the main hospital was enlarged to 300 general medical and surgical cases, making a total of 600 beds available for the care of ex-service men. All patients for observation, treatment, and final diagnosis are received through the eighth district office in Chicago representing Illinois, Wisconsin, and Michigan. A board of three medical officers make a recommendation for the disposition of each case which, ac companied by a clearly stated word picture in the medical history, makes possible a proper compensation adjustment when the case is reviewed by the rating board. A network of subdistrict officers in these States keeps the central office in Chicago supplied with cases needing hospitalization, and after a medical examination, authority for the admission of each patient to enter one of the various hos pitals throughout the district is issued. From 10 to 30 patients are admitted daily at Great Lakes. Each man is assigned to the depart ment especially fitted to care for his particular ailment. On arrival these patients report to the special office representing the Veterans' Bureau which is connected with the receiving ward. A special in patient report card, the Navy Form F card, and an identification card is made out, after which the medical officer takes a brief history of the case, recording the dates of enlistment and discharge from the service, together with the chief points of the present complaint. After a preliminary examination, the patient signs a receipt for a copy of the hospital rules which also contains excerpts from Gen eral Order 27-A issued by the Veterans' Bureau. A short explana tion of the plan of treatment is given to him and any questions answered, so that the patient is sent to his ward with a clear under standing of what is expected of him by the hospital authorities re garding his cooperation in the treatment. All patients pass through a general routine of laboratory, dental, and X-ray examinations. A complete urinalysis is made, also a blood count and blood Was- sermann test. There are repeated examinations of the sputum in all suspicious cases, examinations of the stools of all patients coming from southern Illinois, where hookworm infection is prevalent. A spinal Wassermann test is made on cerebrospinal suspects in ad dition to other observations on the spinal fluid. The X-ray department radiographs and fluoroscopes all suspi cious chests and makes fluoroscopic examinations of all gastro intestinal cases which are referred for an opinion. The dental officers note all cases of infectious and carious teeth for treatment. About 75 per cent of the medical cases are admitted as being possibly tuberculous. Special wards are set apart for these patients and a regular routine is followed. Preceding the first physical ex Xo.1.

The sputum of each suspicious case is examined daily until five to seven negative reports or three positive findings are obtained. In negative cases a second series is started after an interval of one week. Physical examinations of the chest are made weekly. A large number of the negative cases are found to be suffering from nose and throat infections which, when removed, result in a cessation of the symptoms simulating tuberculosis. About 10 per cent of the cases are really tuberculous and are promptly transferred by the district office to a suitable sanitarium. The negative cases are discharged to take up light work, vocational training, or dispensary treatment. The 300 beds set apart for neuropsychiatry cases are generally filled. The average period of hospitalization for this class of pa tients is about 90 days. The larger per cent are neurasthenic and require protracted study by the various departments of the hospital in order to rule out organic disease.

Approximately TO per cent of the neuropsychiatric cases repre sent the various types of psychoneurosis and 20 per cent are suf fering from mental and nervous diseases. Epileptics are trans ferred to their home or to special institutions, and the insane are sent to the Cook County Psychopathic Hospital for further com mitment to a State institution. The majority of the neuropsychiatric patients possess little educa tion and fail to appreciate the problems incurred in settling their claims. The present economic depression has resulted in the hos pitalization of many border-line incompetents. A reconstruction center has been established in Camp Ross with an educational director in charge, to give prevocational training and to gauge the individual's qualifications for a new vocation after considering his educational qualifications, intelligence, past experi ence and present handicap. Courses are offered in elementary academic and commercial branches, also in mechanical drawing, drafting, automechanics, machine-shop practice, electrical, wood and cabinet work, printing, shoe and watch repairing, truck garden ing, poultry raising, bee husbandry, and in the arts and crafts. The local Red Cross chapter is rendering very valuable assistance in obtaining social histories and furnishing financial assistance to dependent families while compensation claims are being adjusted.

Ill The general morale of the ex-service patients has been excellent, and serious infractions of discipline have been few. Every effort is made to assist each patient in straightening out his difficulties and to prevent trivial complaints and misunderstandings from as suming any degree of seriousness. The hospital office of the Vet erans' Bureau is constantly ironing out these wrinkles and keeping an ear to the ground for any echos of discontent. It is significant that only two disciplinary boards have been convened in the past seven months in handling nearly 1.500 nonnaval cases from all walks of life. Upon the recommendations of medical officers daily liberty and periods of leave are granted. Moving pictures and vaudeville are furnished by the Morale Division and various organizations give parties and dances under the direction of the Red Cross hostess. The Bed Cross distributes clothes, shoes, and toilet articles when requests signed by medical officers are presented. The Knights of Columbus distribute cigarettes and toilet articles weekly, and fre quent concerts are given by the naval station band. A well-stocked library and several recreation rooms add to the diversion of ward life. BEPOBT OF THE ACTIVITIES OF THE MEDICAL DIVISION OF THE UNITED STATES NAVAL HOSPITAL, SAN DIEGO, CALIF,i Br W. D. Owbsb, Lieutenant Commander, Medical Corps, United States Navy. The activities of the medical division during the year have been directed to the detailed study of each case admitted and of series of eases of the same disease. This study has been conducted in order that the value of the latest methods of diagnosis and treatment might be determined with the view of establishing a routine for the general management of medical cases. The diseases which have been espe cially studied include thyrotoxicosis, neurosyphilis, acute and chronic nephritis, diabetes mellitus, amebic dysentery, cholangitis, the pneu monias, malarial fever, Vincent's angina, and acute and chronic rheumatism. In each instance observations have been directed along special fields of interest, such as basal metabolism estimations, functional kidney tests, blood chemistry and Allen's treatment for diabetes, intubation and visualization with the duodenal tube, and the location and elimination of foci of infection. Spinal punctures, performed in some 95 of our cases have thrown light upon the frequency of neurosyphilis and the diagnostic value of this procedure. Several cases of atypical, ataxic gastric crisis, neurasthenia and epilepsy in which the blood Wassermann was negative have been determined to be syphilitic by means of the examination of the spinal fluid. Blood 'From the Annual Sanitary Report of the U. S. Naval Hospital, San Diego, Calif. 112 ACTIVITIES OF MEDICAL DIVISION, SAN DIEGO, CALIF. Vol. XVII Wassermann reactions have been determined in all medical cases admitted. Nine cases of thyrotoxicosis have been studied. In this series of cases we determined that, with the exception of basal metabolism estimations, the various other diagnostic tests, including the Goetz and Bram tests, are of little or no value and in some cases do actual harm. Basal metabolism findings, however, are of real value, par ticularly in the differentiation of cases of thyrotoxicosis from "effort syndrome cases." As the result of our studies we have abandoned the other diagnostic tests and confine our efforts to basal metabolism observations. We have learned to accept readings over +10 or +15 as evidence of a hyperthyroid condition. Of the various medical treatments for exophthalmic goiter we have had most success with hydrobromide of quinine. In our hands X-ray exposures have been of doubtful value. Our plan has been to withhold surgery until all medical efforts have failed. In one case, however, on which a partial thyrodectomy was performed, the results have been satisfactory, but only for a limited time. In nephritis we have made certain observations with the functional kidney tests, and have studied the " Fisher treatment." We have not been able to obtain the excellent results claimed by Fisher and have abandoned its use in our nephritic cases. Of particular interest has been our work with the Einhorn tube. Intubation and visualization of the duodenum "has an important field of interest. More than 100 intubations have been done, and our ob servations show that it is an excellent adjunct in the treatment of acute cholangitis, and that its use shortens the course of the disease. It also has considerable value in the treatment of cases of atony of the gall-bladder, and is useful in differentiating between duodenal and gastric ulcers. Visualization with the X-ray of the tube passed into the jejunum, affords an excellent method of determining peri cystic adhesions and assists in the differentiation of cholelithiasis, chronic appendicitis, gastric and duodenal ulcer. With amebic dysentery gratifying results have been obtained by the administration of ipecac by means of the Einhorn tube. The following method of administering ipecac by the duodenal tube has been adopted in our most recent cases : The patient is put to bed under the usual restrictions. An Einhorn duodenal tube is passed on a fasting stomach early in the morning. When the tube is well into the duodenum, 1 ounce of syrup of ipecac, containing 40 grains of the drug to the ounce, is passed through the tube by gravity. This is washed out by a pint of warm water and the tube withdrawn. This treatment is given every morning for 10 days and the course is fthe foundation. " Ethics." therefore, if so well understood, as to an intrinsic part of the nurse, is not learned from a definition, but 137 138 Vol. XVII. NURSE CORPS. from an absorption of the idea that discipline is necessary to develop thoughts and actions in relation to others. The result is respect for teachers, thoughtfulness toward associates, and, in the struggle for mastery in any line of endeavor, mental development, and formation of character. When this home background is lacking the understanding of ethics is so slowly absorbed that the professional knowledge is obtained before the spiritual nature has developed, and the practical prepara tion is accomplished while the qualities of heart and mind are absent or unawakened. Some vocations demand a greater accountability than others. In the profession of nursing the existence and development of the ethical principle is a fundamental necessity. The conception of the ethics of nursing, therefore, is the development to the point of un conscious possession of the characteristics which every nurse should possess, to spend and be spent for others: Truthfulness, not the studied correctness, but involuntary truthfulness; obedience in the meaning of " dutif ulness ; " respect for those in authority, one of the first lessons taught by Christ ; gentleness in speech and manner ; con trol of tongue, abstaining from destructive criticism. " Thoughts Unexpressed may sometimes fall back dead, but God himself can't kill them when they're said." When these characteristics have been acquired there will follow self-respect, dignity, observation, judg ment, and tact. Where these characteristics have been implanted in the home life the correct conception of professional ethics is innate. The defect in the foundation can only be fortified by efforts well directed on the part of those in authority ; and conscious rebuilding without resentment or animosity, on the part of those who have chosen the profession of nursing for their field of work. The incul cation and the willing conception of right principles will innoculate our profession with the knowledge that ethics and ethical standards rest in a rooted feeling that to realize our greatest ideal we must toil and work for the development of our lives in relation to others. Nothing perfect is given to us ; each day we must take up the struggle and live the highest that is given us to live; working, not despairing: not rebellious, but having a mind open to every new and worthy experience.

Medical Service in Modern War, by Lieut. Coli. P. S. Bond and C. F. Martin, ilftlieal Corps, L". a. Army. George Banta Publishing Company, Menasha, Wis., 1920. This is an admirably written pamphlet of 76 pages delineating the functions and tactical employment of Army Medical Department formations and units in a modern campaign. The surgeon with the combatant forces in modern warfare must be more than a surgical operator. He must be well versed in admin istration. He must be forceful and able to organize and direct. Above all, he must be a tactician with the ability to foresee coming events. With this in view, the authors have described, in a general way. the functions of the medical department of an army in the field ; the medical equipment of divisions, corps, and army ; the evacuation and treatment of sick and wounded, and medical service in open warfare. When the United States entered the World War, the Army adopted an organization which was a compromise between American ideas and those of our Allies. This organization proved to be satisfactory, although it was by no means perfect. This treatise is based upon it, but since the war a number of changes have been agreed upon which 141 Ii2 Vol. xvir. BOOK NOTICES. appear to tend toward greater simplicity. These, the authors make clear to their readers. In an appendix will he found some excellent diagrams which illus trate the more important tactical functions with which all officers should be familiar. The Surgeon General of the Army, in a short preface to this work, says: "All officers will find in its perusal a well-arranged and co ordinated exposition of standard doctrine, which is the resultant of the extensive experience of the Medical Department of the United States Army in the World War." Naval medical officers who are taking the Correspondence Course for Medical Officers now being conducted by the Marine Corps Schools, Quantico. Va., will find this pamphlet a valuable addition to their working library, (w. sr. k.) South America from a Surgeon's Point of View, by Franklin H. Martin, M. D.. F. A. C. S. Fleming H. Revell Co.. New York, 1922. This is a delightful collection of notes gathered during two visits to South America during 1920 and 1921 in behalf of the American Col lege of Surgeons, the first visit being made in company with Dr. William J. Mayo, then president of the college, and the second in company with Dr. Thomas J. Watkins of Chicago. The itinerary of the first journey included Jamaica. Panama, Peru, Chile, Argen tina, and Uruguay: the second journey covered the same ground with the addition of Brazil. This book really is a report to the American College of Surgeons; in it are included some observations of Dr. Francis P. Corrigan who, at the time of the second journey, was making a survey of the medical conditions of Bolivia and Ecuador, together with some extracts from papers written by Dr. Martin's traveling companions. The visits to South America were made with the object of securing the affiliation of the surgeons of South America with the American College of Surgeons. Dr. Martin tells in a readable manner of the party's reception and of the hospitality afforded them by the Gov ernments of the various countries and by the members of the medical profession in each city visited. The conditions encountered made a profound impression on the visitors who regard the surgeons of South America in their hospitals and operating rooms as equals of any representative group of oper ators in the world. The book contains descriptions of the medical schools and the hospitals visited, especially in the cities of Lima, Santiago, Buenos Aires, Montevideo, Sao Paulo, and Rio de Janeiro, as well as much interesting information concerning the social and professional con ditions in South America.

Abdominal Pain, by Prof. Norbert Ortner, chief of the second medical clinic at the University of Vienna. Translated into English from the second anil latest edition by William A. Brams, M. D., formerly Lieutenant Commander, Medical Corps, United States Navy. Rebman Co., New York. 1922. Medical men whose good fortune it was to study in Vienna in the days before the war have many pleasant recollections of Professor Ortner. and many of them will welcome an American edition of his book on Abdominal Pain, a work which is the product of many years of personal experience and observation. In a short preface which Professor Ortner wrote for the American edition, he remarks that he hopes the book will be well received, and that it will be of help in reestablishing friendly relations between members of the medical profession of English-speaking countries and of his own. One can assure him that the American medical profes sion at least is willing to meet him more than half way in this recon ciliation, although we fear that it will be some years before the clinics of Vienna attain the popularity they formerly enjoyed. The work is a concise and competent discussion of abdominal pain in all its phases. In abdominal disease one is not often called upon to make a diagnosis on the consideration of the pain alone. There soon develop other symptoms which are of assistance, but the pain often points out the direction one must follow in the objective exami nation in order to arrive at the proper diagnosis. As the author re marks : " It is one of the early symptoms and serves as a guide through the maze of possibilities, and, therefore, it seems justifiable * * * to consider the pain as the starting point in the differential diagnosis." This is not a book to pick up in an idle moment, but one to be read carefully, if one is to extract all the meat it contains. The author considers abdominal pain in the various localities in which it occurs. Hence we find first a discussion of diffuse abdominal pain ; then a section on localized abdominal pain. This is followed by con siderations of epigastralgia or stomach cramps, pain in the right hypochondrium, pain in the right ileocecal region, acute pain in the left iliac region, pains in the lumbar region, flanks and lateral parts of the abdomen, pain in the left hypochondrium. bilateral hypo- chondrial pain, pain in the region of the navel and pain in the hypogastric region. In an appendix various other phases of ab dominal pain are treated fully. 144 Vol. XVII. BOOK NOTICES. Each of these topics is elaborated extensively until every variety of abdominal pain together with associated symptoms have been pre sented to the reader in a systematic manner. Nothing has been left out, and the careful reader gains not only a comprehensive knowledge of the meaning of abdominal pain, but considerable knowledge of the diagnosis of abdominal disease in general. The book is written in the heavy style characteristic of the German school of scientists, but in spite of this handicap it should prove to be a useful volume to one concerned with abdominal disease, (w. m. k.) Diseases of the Skin and Eruptive Fevers, by Jay Frank Schambrrg, A. il., M. D., professor of dermatology and syphilis, Oraduute School of Medicine, University of Pennsylvania. Fourth Edition. W. B. Saunders Co., Phila delphia, 1921. An admirable book which has been revised and amplified in order to bring it abreast of the recent advances in dermatology. Whoever attempts to treat skin diseases should be skilled in the diagnosis not only of the ordinary dermatoses, but of the rashes of the various eruptive fevers. These two classes of affections frequently resemble each other to such a degree as to present great difficulty in differenti ation as is exemplified by the striking manner in which syphilis may simulate smallpox. The differentiation of various skin lesions requires skill which is usually acquired only through years of experience with many patients. Unfortunately most of us do not have an opportunity to develop the diagnostic acumen so often noted in the skin specialist to whom we have referred our puzzling cases and we grope about in the mazes of what seems to us an intricate subject. Should one wish to acquire a good working knowledge of dermatology, or merely to obtain light on an obscure case, Schamberg has written just the book to aid him. Each skin disease is presented in a brief and practical manner, special attention being devoted to symptom atology, diagnosis and treatment. The exanthemata are dealt with in a separate portion of the book and, because of the importance attached to their diagnosis, they are given greater space than is usually accorded them in textbooks. The text is supplemented with excellent photographic illustra tions, which add greatly to the value of the book from the view point of the general practitioner, (w. m. k.) Pneumonia, by Frederick T.

The last of the series to appear is a little book on pneumonia, the text of which was originally delivered as a popular Sunday afternoon lecture at the Harvard Medical School. The book sets forth in nontechnical terms our present knowledge of pneumonia, and con tains valuable suggestions for the prevention and treatment of this disease, (w. m. kl.) The Americanization of Edward Bok. The Autobiography of a Dutch Boy Fifty Tears After. Charles. Scribner's Sons, New York, 1921. " Sir, the biographical part of literature is what I like most," said Dr. Samuel Johnson; and many of us agree with him, especially when the biography is so full of human interest as is the American ization of Edward Bok. Here a strong, honest, upright man has written a book out of his own rich personal experience, relating in simple and convincing lan guage what he has accomplished, giving, as it were, an account of his stewardship and of the intellect with which he was endowed. He has written the story of a little Dutch boy " unceremoniously set down in America " in 1870, unable to make himself understood or even to know what people were saying, but who "by some curious decree of fate " was destined, as editor of the Ladies Home Journal, to write for 30 years to the largest body of readers ever addressed by an American editor. He lived a busy life in his adopted country. At an early age a hobby —that of collecting autograph letters —resulted in his ac quaintance with many of the notable men of the early eighties. Although he possessed enterprise and energy, the continuous good fortune which followed him resulted from the friendships he had made and the men with whom his life had come in close contact at its most formative period. At the age of 21 he became associated with the Scribner publishing house, where he received a training in magazine management which fitted him for his life work. Of course he met obstacles — every suc cessful man does —but obstacles to him " soon became merely difficul ties to be overcome, and he trusted to his instinct to show him the best way to overcome them. He soon learned that the hardest kind of work was back of every success; that nothing in the world of business just happened, but that everything was brought about, and only in one way— by willingness of spirit and a determination to carry through. He soon exploded for himself the misleading and 146 Vol. XVII. BOOK NOTICES. comfortable theory of luck; the only lucky people, he found, were those who worked hard. To them luck came in the shape of what they earned. There were exceptions here and there, as there are to every rule, but the majority of these he soon found were more in the seeming than in the reality. Generally speaking a man got in this world about what he worked for." In 1889 Edward Bok became the editor of the Ladies* Home Jour nal and he was eminently successful, for he possessed the faculty of rightly gauging the psychology of his public. He gave his readers the subjects they asked for, but always " on a slightly higher plane: and each year he raised the standard a notch," and each year the circulation of the magazine increased. No one can doubt the great influence which the Ladies' Home Journal has had on American life, for many of us have noted the changes for the better which have been brought about by its en deavor. One of the first we remember was the alteration in the character of the American small house. The houses of the early nineties were for the most part wretchedly planned, so Bok devoted his attention to better American architecture, gardening, and in terior decoration, with special application to the small house. For 25 years he pursued the plans adopted and in time his dream of better homes came true. " Bok had begun with the exterior of the small American house and made an impression upon it ; he had brought the love of flowers into the hearts of thousands of small householders who had never thought they could have an artistic garden within a small area; he had changed the lines of furniture and he had put better art on the walls of these homes. " It was a peculiar satisfaction to Bok that Theodore Roosevelt once summed up this piece of work in these words : ' Bok is the only man I ever heard of who changed for the better the architecture of an entire nation, and did it so quickly and yet so effectively that we didn't know it was begun before it was finished. That was a mighty big job for one man to have done.' " Bok next turned his attention to certain civic questions —the im provement in the decorations of the Pullman parlor car; the elimi nation of billboard advertising and of untidy spots in prominent por tions of various municipalities; the improvement of rural schools; and the education of women in civic matters, with equal success. The Ladies' Home Journal, under Bok's direction, was the first of America's magazines to refuse to accept advertisements of patent medicines. The magazine attacked the patent -medicine evil from all sides. It aroused the public by showing the actual contents of some of their pet medicines, or the absolute worthlessness of them, and was instrumental in securing legislation which abated this traffic. No. 1. 147 BOOK NOTICES. Then Bok took up the question of venereal disease and he had a lonely fight for a while. But it was a question that had to be faced, and he faced it with a will. There was much opposition from his readers at first, which only proved to Bok that he was right. With a series of well-selected articles he presented his case so ably that soon women began to realize that the Ladies' Home Journal was working for their best interests and for those of their children. In the end he accomplished what he had set out to do. " He had taken the question of natural life and stripped it of its false mystery in the minds of hundreds of thousands of young people; had started their inquiring minds ; had shown parents the way ; had made a for bidden topic a debatable subject, discussed in open gatherings, by the press, an increasing number of books, and in schools and colleges." He next attacked and abolished the public drinking cup; insti tuted the movement for a "safe and sane" Fourth of July, and for " better babies." These are only some of Edward Bok's achievements. His story is fascinating to the very end. It is full of lessons and encouragement for all who are striving to make the world a better place in which to live. Perhaps he was influenced by a sentiment that was voiced by his Dutch grandmother on sending her sons out into the world : "Make you the world a bit more beautiful and better because you have been in it." At any rate Bok believed : " No man has a right to leave the world no better than he found it. He must add something to it; either lie must make its people better and happier or he must make the face of the world fairer to look at, and the one really means the other." (w. m. k.) QUERIES.

To the Ewtob : I was much interested in reading the discussion of the toxic effects of picric acid as commonly employed in the treatment of burns which appeared In the January number of the Bulletin in reply to Ambrine's request. Personally, I am confident that, in spite of all theoretical considerations to the contrary, picric acid is not good to use in burns. I am inclosing a series of com munications from different sources regarding the. treatment of burns, and from them you will see the point of view of men who are probably treating more emergency burns than anyone in the country. I have no doubt that you could get a great deal more data by writing to a large number of industrial plants, out believe this will show quite definitely that picric acid is considered as some what obsolete. Akbustio. The treatment of burns is an important subject and one worthy of consideration by the naval medical officer, as the Annual Report of the Surgeon General of the Navy for the fiscal year 1921 shows 736 original admissions to the sick list during the year for this class of injury. The use of a 1 per cent solution of picric acid is quite routinely em ployed in the treatment of burns throughout the Navy, but the use of this preparation is open to certain objections and, as Ambustio's letter indicates, is not universally popular. It may be that picric acid, by suspending skin respiration and exudation in the areas on which it is applied, or by doing something to a skin area already elaborating a toxic substance as a, result of the burn, or by further irritating a nervous area already irritated to the point of inducing shock, may produce definite injury, but such actions seem never to have been demonstrated, and before we can learn much that is definite concerning such speculative effects, it will be necessary to learn more about the toxicology of burns, which as yet is very obscure. Abstracts of the correspondence referred to in Ambustio's letter are given in order that medical officers may be familiar with treat 149 150 Vol. XVII. QI/EKIES. ment advocated by the surgeons of several large industrial establish ments. It will be noted that these men do not speak against picric acid, but they do not recommend its use. Armour & Co., Chicago, III.: V. S. Cheney, M. D.—" We do not use the picric-acid treatment on any of our burn cases. " We have had considerable experience with the paraffin treatment, and it has given very good satisfaction in extensive burns of the legs and arms due to scalding water. We have also tried the open- air treatment, and in my opinion the result has not been as satis factory with that method as it has with the paraffin treatment. In a great many cases with the open-air treatment we have had exuber ant granulations, with very pronounced scars, resulting in contrac tures; this, however, was in very extensive burns. I believe that the open-air treatment is suitable for superficial burns and those not covering a very large area. I believe that the paraffin method is preferable in burns of the third degree and involving most of an extremity." Tennessee Coal, Iron &■Railroad Co., Birmingham, Ala.: L. No- land, M. D.—" We have conducted rather extensive experiments for a number of years, using a number of different treatments; but for the past four years we have used the so-called ' open treatment ' only, and are satisfied that we are getting very much better results than we ever did with any other type of treatment. "As soon as cases of burn are received in the hospital they are placed on a sterile bed under a bed tent, with electric bulbs inside in sufficient quantity to insure warmth. " When the burned surface begins to dry and crust over, com presses freely moistened with normal saline solution are applied each morning for two or three hours, followed by the easy removal of crusts and necrotic tissue with forceps. If there is a tendency to spreading infection, moist hot dressings of one-half of 1 per cent carbolic acid are used for periods of from 12 to 24 hours, but other wise the open treatment with exposure to light is constant. " We are convinced that this treatment is giving us far better re sults than we have ever secured any other way, with a minimum of pain and scar." Bethlehem Steel Co., Bethlehem, Pa,: Loyal A. Shoudy, M. D.— " Before talking about the direct treatment of burns I should like to call your attention to the care of the patient generally. I find that the burn of itself is not the part which causes the trouble, but the " tox emia " produced. I am not sure that it is a toxemia, but that is the nearest I have been able to come to it. Because of this, in all cases of extensive burns, the general care of the patient must be considered.

In some cases we find it easier to heat the ointment and apply it directly to the burn ; but in most cases we spread it on lint or gauze. "This you will find gives a flexible dressing and enables a man to return to work in the case of hand or finger burns. It is our expe rience that the burns from the hot-metal departments — splashes, and mostly of the feet—are the ones hardest to ' get well.' partly due to the fact that they are mostly third-degree burns, and also that they are in the dependent position.

"In burns of the skin around the eyes we use zinc oxide, with paraffin, as we have learned that it gives better results; why I do not know. " As to picric acid we have not used it for the past six years. " Chinosol I learned from Doctor Murphy's clinic as a general antiseptic." Carnegie Steel Co., Clairton, Pa.: A. W. Colcord, M. D.—In 1910 Doctor Colcord said at a meeting of the Pennsylvania Railway Sur geons' Association : " For the past 10 years I have been using an ointment known as Burn Ointment, old formula, and composed of: Carbolic acid, thymol, menthol, camphor, of each 5 gains; ichthyol, balsam of Peru, of each 10 grains; zinc oxide; starch, of each 1\ drams; petrolatum to make 1 ounce. Mix well. " It occurred to me that carbolic acid had some good properties in the treatment of burns. It is germicidal, a deodorizer, and a local anesthetic, but it is irritating and poisonous. For some years I ex perimented to find a combination which would retain the three good qualities and remove the two bad ones. I believe this mixture has accomplished the result. These four crystalline substances —carbolic acid, thymol, menthol, and camphor—rubbed together produce a new product, which has neither the physical, chemical, or thera peutic properties of either drug taken alone. It is a clear sirupy liquid. You may put your tongue into it and experience only a slight burning. Painted on the unbroken skin, it produces no red ness, pain or gangrene, only a cooling effect followed by a slight local anesthetic. The balsam of Peru and ichthyol, advocated by Doctor Estes, are valuable aids in stimulating granulation and epi dermis formation. The oxide of zinc and starch incorporated in a petrolatum base make of it a protective dressing of about the right consistency. After treating over 2,000 burns with this ointment, I am convinced that it has the following advantages: "1. It is an efficient germicide and not only renders the surround ing skin sterile, but also keeps the discharges and burned surface free from germs and, therefore, free from pus. The only pus cases we get are: " (a) Those who take off their own dressings and so infect the burn. " (b) Those who come after several hours or days with burns al ready infected. " (c) Burns near the mouth, nose, or hair, or near the buttocks in babies. " (d) Possibly some bad sloughing burns of the third degree, but these are treated as soon as a slough begins to form with continu ous wet dressing of Ochsner's fluid, which prevents bad odor or pus. No. 1. 153 QUERIES. "2. It is a powerful local anesthetic and soon stops pain, espe cially in burns of the first or second degree. A badly burned baby, screaming with pain, will often go to sleep from the relief afforded before the bandages are all on. " 3. It is a deodorizer. Our burns have no bad odor except badly sloughing third degree ones, and the odor is best controlled by the wet dressing. " 4. It is nonpoisonous. I have never seen a case where I thought absorption of the drugs produced any unpleasant symptoms. " 5. It is with some exceptions, to be mentioned later, nonirritant. "6. It is easily and quickly applied and convenient to carry in the grip. "7. With this, dressings do not stick as they do with picric acid and many other applications. Men with slight burns can, with this dressing, work in comfort. "8. It is especially adapted to mill and office practice, where we do not have the perfect cleanliness of the hospital and where the open-air (Sneve) dry method or the continuous bath is impracti cable. It is the only method I have found that will keep a burn clean in the dirty homes of some of the foreigners working in the steel mills. "9. The recovery is much more rapid by this method, because (1) the edema and inflammation of the skin soon subside, (2) there is no pus, (3) granulation and epidermis formation are stimulated. " 10. There is less scarring, because less destruction of tissue. " Some years ago I treated 30 cases with picric acid, and there was a general demand from these patients that we return to the ointment. " Let us suppose we are called to treat a severe burn of the second degree. . We find the patient suffering agonizing pain, with oncoming shock and a chill. We at once administer a hypodermic of one-fourth to one-half grain of morphia, one-fortieth to one-twentieth grain of strychnia, and one one-hundredth to one-fiftieth grain of atropin to stop his pain and apprehension and combat the shock. We then see that the room is warm—80° to 85° —clear it of unnecessary furniture and bystanders and order hot-water bottles or hot bricks gotten ready. The bed should also be prepared. If we have a nurse or assistant at hand we can order her to prepare the necessary things for a hypodermoclysis or a Murphy drip. "We must bear in mind that in every bad burn three things are more important than the local treatment. "1. Stop pain. / "2. Combat shock. "3. Provide for dilution and elimination of the toxins, which at once are thrown into the blood. 154 Vol. XVII. QUERIES. " Having gotten thus far with our work, we can proceed to do the local dressing. The clothing should be carefully cut away —never pulled off or dragged over the burned area. We must remember that a burn is, at first, sterile and we must try to keep it so. Unless we believe that it has become infected through dirty handling, dirty clothing dragged over it, or a dirty blanket laid on it, it is best not to wash the burn. Estes washes the surrounding skin with 5 per cent carbolic solution, protecting the burn with pledgets of wet gauze. With our burn ointment we have not found this necessary. " Pieces of gauze of convenient size are now spread thickly with the ointment and applied somewhat beyond the burned areas. Over this cotton and over all a bandage is placed. The patient is now put to bed. and if shock continues the normal salt solution is repeated every eight hours, giving plenty of water to drink. Nourishment for the first three days should be liquid on account of the intense conges tion of the alimentary tract; then we may gradually feed according to conditions. " There should be the usual care of the bowels, skin, kidneys, etc.. not forgetting, in our zeal over the local treatment, that we have on our hands a sick man with blood loaded with toxins, with meninges, lungs, stomach, kidneys, and other organs congested. u We re-dress our burns daily, gently wiping away the discharges of serum and broken-down cells, which is poisonous and irritating, with dry gauze or cotton. Blisters are opened and pieces of loose skin removed with sterile scissors or forceps, but all skin is left in place as long as possible to protect the underlying, new-forming skin. " Every dressing should be made with aseptic care, clean hands, clean gauze, and clean instruments. ''As the old epidermis is shed we have a red, raw, irritable sur face, and we must reduce our ointment to one-half or even one- fourth strength.1 In an occasional case even this is too irritating, and we change to oxide of zinc ointment, or. better, to strips of gutta percha tissue wet in normal salt solution. When the islands of epi dermis have coalesced, we can change to aristol or any dusting pow der. " Of course, the greater number of burns are not so extensive, have no shock, and come to the office for daily dressing. " In burns of the third degree the initial stage of shock, pain, and toxemia is treated as in extensive burns of the second degree, and the ointment applied. As soon as the slough begins to form, if there is much odor, it is well to change to a continuous wet dress ing; we prefer Ochsner's fluid (or Dakin's solution) with gauze. 'In a personnl communication Doctor Colcord states: "We now use on practically- all burns an ointment : Burn Ointment —old formula, one-sixth ; 5 per cent boric acid In white vaseline, flve sliths." No. 1. 155 QUERIES. cotton, and bandage. The patient or nurse is given a bottle of the fluid, which is poured on every three hours without removing the bandage. The burn is re-dressed daily, and sloughing masses are re moved when ready. We often see new epidermis forming along the edges before the slough has all come away from the deeper parts. The sloughing area is rapidly filled with red granulations, and if kept clean, the epidermis from the edges starts to cover it. During this period we usually apply the ointment daily, one-half strength, using silver nitrate if granulations are too high at the edges. Where ulcers, following deep burns, are sluggish with a poor blood supply at the base, balsam of Peru or bovinine is used daily. " When the area is large in a third-degree burn, skin should be grafted as soon as the slough is well away and the hole is filled with granulations. To wait until the granulating mass is old and high, we not only invite failure of the grafts to take, but we have a mass of scar tissue formed which will eventually contract, with resulting deformity. " Murphy says : ' In late grafting where a heavy mass of connec tive tissue forms beneath granulations, I advise that this be dissected out, down to the normal fascia, muscle, bone, or other tissue beneath, before placing the graft.' " We use mainly Reverdin or Thiersch grafts, covering with gutta percha tissue strips and wet gauze dressing of normal salt or borax solution. "' Young, of Glasgow, following the method of Wolf, Krause, and Matas, has obtained some excellent results by grafting the whole skin with the subcutaneous fat removed. He claims much more perma nent results than with the other methods, greater elasticity and better appearances. " Much of the ugly scarring and deformity resulting from third- degree burns is due to the neglect of skin grafting. It is often done too late or poorly done, and in many cases not done at all. "Reverdin grafting can be performed without an anesthetic and at the home of the patient. No apparatus is needed but some gutta percha tissue, a pair of sharp scissors, mouse-toothed forceps, and some sterile salt solution. The wound surface and surrounding skin must be clean, the granulations firm and healthy, and there must be no bleeding. If near a joint, apply a splint to insure perfect rest, keep the parts constantly wet with normal salt solution. Leave the strips of gutta-percha tissue in place three days, then change to clean strips. Put on grafts, one-half inch apart, in rows, both ways, so that the strips may be crossed like basket work.

"This can bp put in the eye where the burn is on the eyeball or under the surface of the lid. and gauge and bandage applied. These burns also do well with a wet dressing of boric acid solution. When the cornea is burned, atropin is used.'' In a recent communication Doctor Colcord said : " In my address before the Pennsylvania Railway Surgeons' Association. I reported the treatment of 1,000 burns with no clinical infection. I can now add 9.000 more to the list. Nurses, assistants, and patients have al ways been enthusiastic about the results of this ointment. As you will note, I am now using it much weaker than at first. "Am just finishing the treatment of a very deep third-degree elec tric (6,600 volt) burn, destroying skin, facia, and a portion of mus cles of ball of thumb. Slough was 2 by 3 inches and three-fourths inch deep. Ointment used first four days. Then a constant wet dressing of 10 per cent Dakin. mopping slough daily with pure Dakin solution. Skin of hand was protected with the Burn Ointment. Swelling of hand was slight and soon subsided. There was the usual amount of discharge from a rapidly dissolving slough but no signs at any time of clinical infection about the burned area. As soon as slough was complete I returned to the Burn Ointment and the cavity rapidly filled with healthy granulations covering in from the edges with epithelium. I had told the patient that skin grafting would be needed, but the new skin came so rapidly that I did not use it. Throughout his treatment he has been free from pain and has worked in comfort. There has been no perceptible odor. I cite this case as typical of our treatment and its results. " I treated 200 cases with paraffin and got good results, but not nearly so good as with the ointment. The paraffin does not prevent infection, does not deodorize, does not provide for the carrying away of the discharges, does not tend to sterilize the surrounding skin, but on the other hand keeps the wound discharges in close contact, per mitting them to become infected by the pus germs ever present in oil glands, sweat glands, and hair follicles, and so carrying infection to the burn. In about 25 per cent of cases I got pustules or furuncles around the burn. Yet paraffin has great advantages and has been an advance over the antiquated methods in vogue before the war or those used to-day by many otherwise good surgeons.*' From a communication recently received by the editor, the follow ing is quoted : No. 1. 157 QUERIES. " 1. For burns, either erythematous or vesicular, in which the epi dermis is not broken, I use picric acid. "2. (a) For second or third degree burns in which the epidermis is removed. I use the open-air treatment, with some means for main taining desiccation of the surface. "(b) If, however, infection supervenes and the crusts are inter fering with drainage, I saturate the individual with citric acid in ternally, and keep the parts wet with citrated solutions until the in fection is overcome. I then revert to the dry treatment (2 a) or the pus dressing (3). "3. The tissues in the neighborhood of a burn always show, as you know, signs of damage from the heat, a condition similar to that produced by therapeutic thermo-coagulation, so that a prolonged period following the injury is occupied in repair of damage before definite healing processes start. " When the healing process is well under way, as shown by healthy granulations and advance epithelium, I use my old pus dressing— a sheet of rubber dam covering the whole granulated area. The theory of this dressing is: (1) It protects the granulations and tender epidermis from mechanical injury, (2) conserves all the exudate, which, in clean wounds, consists of nutritive and reparative mate rial, and (3) by the conservation of this exudate, the young, ' naked ' cells and capillaries are bathed in fluid which is not only nutritive but ideally adapted in chemical constitution, being far superior to any salt solution that we can concoct. " I speak at length of the theory of the ' pus dressing,' since the rationale of paraffin dressings is,I believe, identical. Consequently, I regard the healing period as the indication for paraffin, if it is to be used at all." The Bulletin woidd welcome the ideas of individual medical officers on the subject of the treatment of burns in order that it may present to its readers treatments which have been found to be effi cient. THE DIVISION OF PREVENTIVE MEDICINE. Lieutenant Commander K. F. Jones, Medical Corps, United States Navy, in charge. Notes on Preventive Medicine for Medical Officers, United States Navy. INSTRUCTIONS TO MEDICAL OFFICERS. THE VENEHEAL DISEASE PR0B1EH. By Pail Richmond, Jr., Ueutenant. Medical Corps, United States Navy. The problem of combating the venereal diseases lias not been Bolved either for the Navy or for civilian communities. Comprehen sive and well-defined plans are being carried out to reduce the harm ful effects of other communicable diseases but considerable difference of opinion exists as to the best method of procedure in directing activities aimed at minimizing the incidence of the venereal diseases. During the World War the liberal contributions of patriotic citizens and popular enthusiasm made it practical to carry out more extensive measures than had previously been possible. Resulting therefrom there was a widespread suppression of the old type of " restricted district" which has changed the outward aspect of commercialized prostitution. Another factor influencing the problem has been the advent of prohibition. It is, therefore, difficult to compare present conditions with pre-war standards. From 1910 until the beginning of the war there had been a gradual reduction in the annual admission rates for venereal disease in the naval service. By some, this diminution has been attributed to the more general use of medical prophylactic treatment, whereas other medical officers claim that improved conditions in seaport cities as well as more extensive instruction and warning of the men were the determining factors. This was true especially in those cities where restricted districts and other resorts of commercialized pros titution were closed. During the two years of the war the rates suddenly fell to not much more than half the pre-war rates. Undoubtedly this was due to many influences : the causes tabulated below are listed in what is believed to be the order of their importance : 1. Enlisted men of a higher type than in time of peace. 2. Improved social status of enlisted men. 159 160 Vol. XVII. THE VENEREA!, DISEASE PROBLEM. 3. Suppression of all forms of prostitution in the vicinity of naval establishments and in seaport cities in the United States. 4. Prohibition of alcoholic beverages for men in uniform. 5. Military activities occupying a greater portion of the men's time than normally. 6. Improved facilities for recreation and amusement. 7. More intensive instruction as to the nature and dangers of the venereal diseases. 8. Patriotism, with a desire to avoid sickness during war. Since the war the rates have again reached almost to the 1916 level and are about where they would have been if the pre-war rate of decline had continued uninterruptedly. Inasmuch as the low war rates were not destined to be lasting in spite of a continuance of as many activities aimed at reduction as was possible, the questions have been repeatedly asked: "What should be done in the future and what permanent policy should the Bureau of Medicine and Surgery adopt in regard to these diseases?" and "Should the propaganda against venereal disease be abandoned or should new lines of activi ties be sought?" Before undertaking to answer such questions an analysis of the possibilities of present methods will be attempted. Inasmuch as the type of the men enlisting in the naval service in time!- of peace is more dependent on conditions of industrial employ ment and wages in civil communities than on service inducements, it remains only for officers on recruiting duty to select the best men who present themselves for enlistment. Since this policy has always been carried out, it may be presumed that the best types of men available have been and will in the future be obtained, so that ef forts from within the service can not be expected to make any par ticular improvement in this factor. Suppression of prostitution can not be undertaken by the naval service. However, such organizations as the Interdepartmental So cial Hygiene Board, the American Social Hygiene Association, and many local agencies are active in this field and have gone, far toward eliminating open prostitution in the United States. Women's po litical clubs are especially interested in this matter and are able to exert so much influence on mayors of cities, city and State boards of health, and police officials that few cities will again tolerate open prostitution. As a result of these activities, prostitution in the United States is rapidly assuming a clandestine form and, as active suppression continues, women of this character will be more and more difficult for men in the naval service to find. This has already been reported to be an important factor in reducing exposures in San Diego, Calif., where strenuous measures were employed to sup press prostitution. On the other hand, medical officers of ships re No. 1. 161 THE VEXEREAL, DISEASE PROBLEM. port that the exposure rate increases markedly when liberty is given in European or South American ports where prostitution is unre stricted. The active suppression of prostitution by municipal po lice authorities promises more in the way of reducing the incidence of venereal disease in the naval service than any other available measures. The venereal rate for military forces in the United States- should gradually improve as the practice of prostitution becomes more precarious. While many men will continue to Hud prostitutes in every large city, solicitation by the women will cease to be a con siderable factor. However, many men, especially those recently en listed and those whose sexual habits are irregular, will often be dis appointed in their search. Medical officers may occasionally render assistance to the local authorities by reporting foci of infection. The commanding officer by bringing pressure to bear on those in po litical power can aid in improving conditions. But, in the main, the Navy can not take an active part in solving this phase of the problem. -Nation-wide prohibition by reducing the amount of drinking is thought to have reduced the number of exposures to venereal disease. Many men are restrained while sober, but when intoxicated tend to seek out and associate with prostitutes. Medical officers on ships visiting foreign ports almost invariably mention drunkenness as a factor in increasing the number of venereal infections. Men under the influence of alcohol are notably careless concerning exposure and prophylactic treatment. The facilities for amusement, recreation, and athletics are recog nized as of great importance in reducing exposure to venereal disease. Inasmuch as the Morale Division of the Bureau of Navigation has funds with which to aid ships and stations, there is no reason why every ship and station should not have adequate amusements, etc., for >ts complement, when the officers take an active interest. Medical officers, in general, encourage athletics and other recreations among the men, as such activities have a beneficial effect on the body and thus diminishes all forms of physical disability. Although indirect this K one of the best methods of reducing the incidence of the venereal diseases especially since the war, when the men have more spare time and less engrossing duties. Its preventive value is believed to be in direct proportion to the character of the men, however, for some types of individuals will not be restrained to any appreciable extent. In the matter of instructing the men as to the nature of venereal disease and warning them as to the dangers of such diseases, the medical officer has definite obligations and should have a broad view °f the problem in order that he may not be discouraged if his efforts are often apparently futile. It is important that those phases most likely to have a lasting beneficial effect, however small, be emphasized, out fallacies which lead to opinions which can not be defended and 162 Vol. XVII. THE VENEREAL DISEASE PROBLEM. are contrary to the policies of the Navy Department must be avoided. The first consideration of educational measures aimed at the preven tion of venereal disease is the prevention of promiscuous sexual rela tions. The number of cases of venereal disease will bear a definite ratio to the number of exposures, i. e., after all other factors have reached the best possible efficiency. From a study of the Forms A from all ships and stations for a period of a year and a half, it appears that many medical officers give this phase of the problem little or no consideration, but concentrate their efforts on instructing the men how to use prophylaxis. Those having tried to reduce the number of exposures by instructing and warning the men of the dangers of venereal disease are divided as to whether any reduction has resulted. A few report that " much good was accomplished," others state that " it is believed that the pamphlets, posters, and lec turers do good." A great many more medical officers state that " the men continue to expose themselves in spite of intensive instruction as to the nature and danger of the venereal diseases, both by lectures and the distribution of the literature provided." Although the actual restraining power of such propaganda can not be measured, some men are known to be influenced thereby. Whether such instruction will be of any avail is believed to be entirely due to the individual man's moral viewpoint. The group of men who believe that promiscuous sexual relations is morally wrong in the same way that theft, lying, and other forms of dishonesty are con sidered wrong can, it is believed, be dissuaded, in great part, from what they consider lapses of morality. The number of exposures for this class can thus be greatly reduced. However, similar propa ganda is of no avail for that group who regard promiscuous sexual intercourse as a matter for individual choice, in the same way that the use of alcohol is usually considered, and who do not attach any moral stigma to those practicing such irregular sexual relations. The exposure rate may, nevertheless, be reduced in this class by caution ing the men to avoid intercourse with prostitut«s, who are practically all diseased. Opinions on this subject are usually fixed before men enter the service; consequently the influences of later environment and teach ings to change the viewpoint are of no avail, except in the occasional instance. The lack of success experienced by medical officers who have given the propaganda a thorough trial is attributed mainly to the relatively small number of men in the first group, as well as to the fact that such instruction may have been given at a time when oppor tunities for sexual relations were especially numerous and attractive. For instance, this seemed to be true on the U. S. S. Utah in Mediter ranean waters where the monthly exposure rate exceeded the number of the complement. Certain variations in exposure rates must be due No. 1. 163 THE VENEREAL DISEASE PROBLEM. to other factors also. For example, in case of the U. S. S. KUtery and the U. 8. S. Gulf port, which regularly visit practically the same West Indian ports, each medical officer states on Forms A that he instructs and warns the men of the dangers of venereal disease. For the last quarter of 1921 the U. S. S. Gulf port, with an average com plement of 92, reported 2,746 exposures, whereas the U. S. S. Kittery, with an average complement of 121, reported only 191 exposures for the same period. Such variations in the exposure rates, where other factors appear to be the same, can possibly be attributed to the example set by cer tain men among the crew who, by their conversation and conduct, more than neutralize any beneficial effect produced by educational measures. Such environmental influences induce many men to seek sexual gratification much more frequently than the}- would otherwise be inclined to do. This may also be a factor on large ships and shore stations among any particular group of associated men. The writer had occasion to observe such an example among a group of Hospital Corps men. following the arrival of a pharmacist's mate whose sexual habits were unusually irregular. Although transfer of this man to other duty did not immediately reduce the rate of exposure to aver age, a much more salubrious character of conversation immediately prevailed among the corps men. Unfortunately, recruits get most of their information or misinformation from conversation with other enlisted men " between decks." For this reason is it to be wondered that an occasional talk by the medical officer, however forceful, can not displace the effect of the continual reiteration of fallacious statements? Fear of disease is rapidly dissipated when an ''old timer" tells of his "career" and appears none the worse. As these conditions can not easily be changed, those carrying out ed ucational measures will have to be contented with scant evidence of improved rates for venereal disease. Recently a case of syphilophobia was reported to the Navy Department. From this it can be seen that our appeal to the fear of disease may do harm in some instances. Instruction as to the value and use of the new form of medical pro phylactic treatment must continue to form a part of the educational program. The percentage of infections following any form of pro phylactic treatment in a large group of cases is a good index of the relative value of such measures. Tabulation from Forms A of over 36.000 treatments given within one hour after exposure indicate that i.' per cent of infections may be considered the average rate of disease following early treatments by the methods applied during 1921. It is expected that the use of the prophylactic packet will reduce the ratio for all exposures to this minimum. Present methods are deemed both justifiable and adequate. New departures are not to be looked for. nor should existing measures be 164 Vol. XVII. THE VENEREAL DISEASE PROBLEM. despaired of. The venereal diseases result from human conduct which follows age-long customs. As social conditions generally improve the venereal diseases must diminish. In southeastern Europe a social collapse has produced the inevitable increase of these infections. In asmuch as the sexual impulse depends on a primitive instinct it can not be expected that promiscuous sexual relations will diminish faster than other forms of antisocial conduct. ABSTRACTS FHOM THE ANNUAL SANITARY REPORT, FLEET SURGEON, UNITED STATES ATLANTIC FLEET, FOR THE YEAR 1921. A review of the health statistics of the fleet for the year 1021 shows rliat, as far as sickness and injuries are concerned, the return to peace-time conditions lias been practically fulfilled. By this it is meant that the admission rates per 1,000 for diseases and injuries now approximate those rates that were in ex istence prior to the entry of the service into the World War. The returns avail able for examination indicate that there is improvement in nearly all classes of diseases and injury. In fact, it can be stated with more optimism than for many years that the health of the fleet during the year 1921 has been excellent. The admission rate for the entire Navy for the previous year was 07(3 per 1,000. For the 5-year period immediately preceding the war the mean rate was 464 per 1,000. Therefore, the annual rate of 398 per 1,000 for the year 1021 may be considered as reflecting very satisfactory health conditions in the fleet. Communicable diseases.—About 22 per cent of the total admissions to the sick list belong to those ailments classified as communicable. The kind and number of each of the communicable diseases that occurred in the tieet during the latter half year are as follows : Diseases and number of Admissions. Tonsillitis 665 Influenza '9 Cellulitis 71 Abscess (all) 39 Pneumonia (all) 25 German measles 22 Fever, unknown cause 21 Furunculosis 18 Malaria 17 Chickenpox 16 Measles 13 Tuberculosis (all) 11 Mumps 8 Rheumatism (all) 6 Scarlet fever 4 Erysipelas 2 Diphtheria I Dysentery 1 Total 1.019 There were 605 admissions for tonsillitis, which amounts to about two-thirds of the total number of admissions for these communicable diseases. Next in importance to tonsillitis is that group made up of those diseases caused by the pus-forming organisms ; that is, cellulitis, abscess, and furunculosis. Tonsil litis and the latter group have a total of 803 admissions, or about 80 per cent of the entire number of admissions for the diseases of tins class. It is singu lar that miliaria, measles, mumps, chickenpox, and other similar diseases have such low admission rates. Unfortunately, the two diseases most menac ing to life, pneumonia and tuberculosis, are represented by a considerable number of admissions. No. 1. 165 THE VEXEREAL DISEASE PROBLEM. The above table shows that tonsillitis anil diseases of the pus-forming or- pmisnis are the principal contributors to this class of communicable diseases and that if it were possible to control these contusions a relatively large amount of sickness would be avoided. An explanation as to the reason for the predominance of these two diseases can not readily be offered. It is prob able that a predominance of tonsillitis and diseases of the pus-forming organ isms is due to some defect in ship sanitation. Unfortunately, no definite state ment to this effect can be made. But whenever the admission rate for one or both of these diseases is unusually high, experience indicates that the condi tion of the sculleries, drinking fountains, and other similar sanitary factors should be carefully examined with the view of finding the probable cause of the increased incidence. Smallpox and typhoid fever. —During the latter half of the year there was no admission for smallpox or typhoid fever. Two isolated cases of modified smallpox occurred in the first half of the year. These two cases were handled with a minimum of inconvenience to the fleet. It is believed that the Atlantic Fleet is now fully protected against typhoid fever and smallpox. If either of thes»> diseases appear, it is quite certain to be in a mild or modified form. Therefore, it is improbable that the health of any persons in the fleet will be jeopardized by their contracting smallpox or typhoid fever, or that the move ment of the fleet, or any ship of the fleet, will be restricted on account of the appearance of either of these diseases. Fatalities. —A total of 29 deaths occurred among the personnel of the fleet . during the year. Of these, 8 were due to natural causes and 21 to external violence. Of those due to disease. 3 were caused by pneumonia, 3 by inflam matory brain affections, and 1 each was due to acute peritonitis and dilatation of the stomach. The following is a summary of the 21 fatal accidents: Drowning " Fell overboard tone unwitnessed) 3 Swimming (one unwitnessed) 3 Capsizing of canoe (unwitnessed) 1 Suicide (unwitnessed) * Fell overboard on watch (unwitnessed) 1 Airplane accidents 3 Crash 2 Caught by revolving propeller 1 Street accidents Trolley car 1 Fell down street stairs 1 Coaling, drawn into winch * Engine room, bursting steam pipe 1 Asphyxiation, working in confined space (unwitnessed) 1 Drug poisoning, drug addict 1 Homicide, unwitnessed Fall on board, unwitnessed Jumped in front of train, suicide 1 21 It is seen from the above that drowning as a cause of death leads all other causes. It is natural to expect that the hazard of drowning is greatest In a seagoing occupation. Consequently, there are many recognized precautious that are constantly being enforced. But in spite of all these, drowning accidents 166 Vol. XVII. THE VENEREAL DISEASE PROBLEM. occur. Accidents resulting from swimming and men falling overboard account for the greatest number of drownings and these are difficult to guard against. Of course, no man should be permitted to enter a swimming pool when no other person is present, and the breaking of this rule seems to have accounted for one death. Each year a number of deaths occur among swimming parties. The unnoticed disappearance of a member of such a party is a frequent occur rence. To prevent this a plan has been suggested by which the members of a swimming party pair off before going into the water, each one of a pair to be responsible for the safety of the other. Under such a plan the occurrence of an unnoticed disappearance of a man would seem quite improbable. The fleet regulations require that care be taken for the safety of the lives of the personnel, in particular, when new activities are being carried on, and. also when conducting activities known to be hazardous. Furthermore, there is an order that when an accident resulting in a fatality occurs a copy of the board of inquest or investigation, as the case may be, shall be furnished the commander in chief. These reports are carefully considered to ascertain if blame or responsibility for injury to personnel can be attached to any person or persons, and also to determine if it is possible to institute any safe guarding or precautionary measures against the recurrence of the same or a similar accident. Venereal diseases. —According to incomplete statistics collected within the fleet during the past year it appears thnt the venereal situation for 1921 will . be relatively good. Calculations for the last half of 1921 give an annual rate of 102 per 1,000. The rate for the entire Navy for the previous year was 126 per 1.000. and for the year before that 111 per 1,000. The last half of the present year does not include the period during which the fleet is at Guantanamo, when a comparatively small number of infections occurs. It does not seem improbable that when a complete calculation is made the venereal admission rate of the Atlantic Fleet for 1921 will be found to compare favorably with the low rates of the war-time years. The last annual report of the Surgeon General of the Navy notes that " in general * * * the rates for the venereal diseases were lower for shore stations than for the entire Navy." It appears that the reverse is true for the Atlantic Fleet for 1921.1 The rate of 102 per 1,000 is small for a force afloat. It would be worth while in the interest of further prevention to deter mine, if possible, the reason for this reduced venereal rate. This year medical prophylaxis and educational propaganda were carried out with about the same amount of zeal as during previous years. The presence of a less changing personnel might be assigned as a cause for fewer communicable diseases, but this condition would appear to be practically without effect to reduce the number of venereal diseases. It is probable that the favorable results of 1921 followed some definite cause or causes. In attempting to annlyze the venereal situation it should be taken into consideration that the enlisted personnel nowadays, in consequence of various propaganda that have been forced upon it, is better informed concerning venereal matters than formerly. Also, vice conditions on shore have changed. In the past the sailor was often exploited by commercialized vice, which Is seldom the case any more. When the present-day sailor encounters vice on shore it is probable that he has sought it instead of the vice having sought him. In other words, the sophistication concerning venereal matters which 1 Provisional statistics In the Bureau of Medicine and Surgery do not bear out this statement. The admission rate for venereal diseases for 1921 for shore stations was 73 per 1,000 per annum. No. 1. 167 THE VENEREAL DISEASE PROBLEM. ihf enlisted mau now possesses has resulted more in his avoiding the conse quences of his moral transgressions than it lias in bolstering up his better inclinations. The administering of prophylactic treatments on board ship has many ob jectionable features. Among them, and not the least of them, is the attending publicity, which tends to dull the moral sensibility of th>> applicant for treat ment. The fact that the taking of medical prophylaxis is considered a require ment after an Illicit exposure has resulted in a great many untrue statements being made to the attendant in charge, and, consequently, considerable erroneous data are now entered in the prophylactic records. Many men are providing themselves with their own methods of prevention. If the method fails, or If the individual believes it to have failed, he takes a treatment on board ship, thereby having his name recorded and giving any number that happens to come into his mind as the number of hours after exposure. It is probable that this practice, more than anything else, causes the high percentages of failures and, without doubt, the erroneous percentages that are now being obtained on Form A. A summary of the Forms A from the fleet for six months, representing an average complement of 23,414, is as follows : Hour. 1 2 3 4 5 6 6 to 12 . . Over 12. Number of treatments. 3, 952 4, 403 2,851 2,151 1,411 1,253 2,073 837 Diseases. 66 110 106 87 r,i 64 126 68 18, 931 088 Per cent. L6 2.4 3. 7 4.0 4.3 5.1 6.0 8.1 3.6 It is seen in the above table that the percentages of failures for each hour after exposure are unusually high. The inference is that medical prophylaxis In the fleet has been particularly unsuccessful. It seems inconsistent to have among the same personnel a high rate of infection following prophylaxis and at the same time the low rate of admission of 102 per 1,000 per annum previously noted. This phenomenon may be explained by the suggestion already advanced ; that Is, that the enlisted man, through greater knowledge of the subject, is seeking In his own way to avoid venereal disease. Some men are avoiding disease by comparative or absolute continence, while others resort to various mechanical or medicinal means of prevention. The result is that, the ship's prophylaxis is used to cover up errors or neglect, thereby causing a considerable distortion of the compiled results. On the other hand, there is a better appre ciation on the part of the crews at large of the dangers of illicit intercourse. This is associated with a more intelligent effort to avoid or prevent infection, which is apparently the cause of the low rate per 1,000. 168 HEALTH CONDITIONS OF THE NAVY. Vol. XVII. HEALTH CONDITIONS 07 THE NAVY. The iinnual admission rate for all causes, entire Navy, for the five-week period ending June 10 was 488 per 1,000 per annum, as compared with a rate of 506 per 1,000 per annum for the previous four-week period ending: May G. The progressive average rate for the entire Navy on June 10 was 624 per 1,000 per annum, which is considerably lower than it has been at any time during the year or. in fact, at a similar time for the past four years. There has been a gradual decline in the annual admission rate for diseases only since about the 1st of March; the admission rate for the five-week period ending June 10 was 422 per 1,000 per annum. The morbidity rate for accidents and injuries for the week ending June 10 was higher than it has been at any time during the past two years, the rate being 1)2 per 1,000 per annum. The average rate for accidents and injuries for the five-week period ending June 10 was 66 per 1,000 per annum. The morbidity rate for communicable diseases continues to be very low.

German measles has been reported from several battleships of the fleet; this, no doubt, accounts for the high rate for this disease. Malaria has not only been prevalent among marines stationed on foreign shore service, but also at Quantico, where there were 31 cases admitted during the past month. No. 1. 169 HEALTH CONDITIONS OF THE NAVY. The morbidity rate for the venereal diseases has continued to de cline during the past five-week period, the progressive average now beinear that South Carolina, with two and one-half times the population of Rhode Island, was reporting about three times as much syphilis per capita. In the " Report of the Percentage In the Second Million of Drafted Men Found Infected with Venereal Disease" (war statistics). South Carolina stood fourth, with 13.1 per cent, and Rhode Island was thirty-fifth, with 2.8 per cent. The average for the whole United States was 5.7 per cent. We expect, then, to record a higher morbidity rate for venereal diseases when the destroyer squadrons are in Charleston than is recorded at Newport. This is borne out by the actual returns. The situation in Charleston and its adverse effect on the personnel is com mented upon in several of the Annual Sanitary Reports for 1921 submitted by the medical officers attached to this force. Charleston, on the other hand, recognizing the desirability of having this force make this port a permanent base, has begun a clean-up eompalgn. The first step was taken during the summer before the destroyers returned. The white vice district was closed. The local follow-up efforts have not been as energetic nor as effective as the first steps. Prostitution is still rampant. Real improvement of vice conditions probably will be slow in becoming manifest. This is an inherent defect in our present political conscience. The clean-up idea is merely dormant now and may at some future date eventually carry Its point. Economic pressure has been the factor most useful In getting results. All local effort has been entirely on the initiative of the residents themselves.

The former practice of maintaining a first-aid and prophylactic station on the Government landings at Charleston and at Newport has been continued. ABSTRACTS FROM THE ANNUAL SANITARY RETORT, U. S. S. "PENN SYLVANIA," FOR THE YEAR 1921. During March, 1921. while anchored in Guantanamo Bay, Cuba, an epidemic of acute bronchitis occurred aboard this vessel. There were approximately 100 cases. In order to cope with the epidemic about 50 per cent of the cases were transferred to the hospital ship Relief for treatment. The cause of the epidemic was undoubtedly due to infection with Pfeiffer bacillus. The infec tion was either airborne or carried through the agency of mess gear. The symptomatology common to all of the cases was a nonproductive cough, mild fever, tightness and constricted sensation of chest, headache, and moderate prostration. There were seven battleships at Guantanamo during the period of tliis epidemic, but five of them had no cases. A similar epidemic occurred at this time on the U. S. S. North Dakota. Acute follicular tonsillitis has been prevalent during the year. This disease lias not appeared in epidemic form, but has been endemic, there being always one or two cases of tonsillitis reported on the morning report of sick. The cnuse of this disease is believed to be due in large part to nonsterllization of the mess gear. The condition of the decks—worn-out linoleum with residual water beneath —has probably been a contributing factor at times when repair was delayed. The etiology of these cases has been carefully studied, and certain ones have been found to closely follow exposure to wet and cold weather. Defects in the ventilating system may also contribute to the etiology of this disease. Throat infections by Vincent's organism were common while this vessel was "n the Atlantic coast, but since a change of station occurred in September, 1921, to the Pacific coast, Vincent's angina has rarely occurred. The influenza cases occurring during the latter part of 1921 have been char acterized by marked selective action for the nervous system. The symptoms were mild fever, with cough or pulmonary symptoms; mild rhinitis; severe neuralgias, usually of head, face, or neck ; and prostration disproportlonal to the mildness of the other symptoms. Recovery from attacks has been compara tively rapid. The absence of certain diseases which were present in 1920 is noted with satis faction. There has been no case of cerebrospinal fever, typhoid fever, or lobar pneumonia. Three cases of encephalitis lethargtca occurred during January, 1921. Two of these cases terminated fatally on board the U. S. S. Relief. Several cases of subtertian malarial fever occurred among members of the marine expeditionary force, which was aboard this ship while at Panama in Anzust. 1921. These cases attracted interest, as it was definitely found that the infection did not occur in the Tropics. The cases occurred too soon after arrival at the Isthmus of Panama to permit of the belief that the infection had hec-n acquired there. As these men had been stationed at Quantico, Va.. prior to embarkation, and as they had never lived in the Tropics previously, it is as sumed that they were infected while serving at Quantico. 174 Vol. XVII. health conditions of the navy. Preventive measures against epidemic diseases have been carried out aboard ship in routine manner. The sanitary drinking cups are burned out with a gasoline torch daily. Linoleum decks have been washed down with cresol solution each morning. Air-bedding orders have been made to include officers' bedding. Divisional officers and crew have been instructed by medical officers regarding venereal diseases and the prophylaxis and hygiene relating thereto. Instructions regarding typhoid prophylaxis and vaccination against smallpox nave 'jeen carried out scrupulously and energetically. The principles of venereal prophylaxis have been rigidly enforced. Disciplinary measures for failure to take venereal prophylaxis have been very rarely used. Ventilation. —There has been no change made in the structural details of the ship's ventilating system since certain recommendations were made in the sanitary report from this vessel for the year 1920. The deficiencies of the supply system reported, upon at that time are in no way improved and are found to be worse on the third deck and in the storerooms below. Late in 1921 the main air ducts leading forward and aft from the forward air-intake vents were examined and the following conditions found : The walls of the ducts were entirely covered with impacted black soot to a thickness of 2 to 3 inches. In other words, the lumen of the main air ducts was reduced from 2 to 3 inches at the place of their largest circumference and their air- carrying capacity was proportionately reduced and choked by the accumulation of dirt and soot on their walls. The insanitary aspect of this condition is most obvious. So much soot is blown through the terminal louvers that it becomes necessary in many com partments to filter the air through gauze veils tied over the louvers. While this plan acts to keep out dust and dirt, it also reacts to diminish the air supply. The presence of dirt at each end of a ventilating system indicates that the entire system Is air choked and in consequence is incapable of functioning to full capacity. It Is natural that the smaller ducts should be most affected by this condition, and consequently it is in the storerooms that the air supply is most deficient. The dangers from insufficiently ventilated storerooms have recently been made the subject of a special bulletin sent out by the Bureau of Medicine and Surgery. Vcmrrnl dixenxcx. —Preventive measures against venereal infections have been carried out through the agency of warning posters, venereal prophylaxis, and instruction to the divisional officers and crew by the medical officers. On such occasions emphasis has been placed on instructions that eontinency is the sure preventive against venereal diseases. Venereal prophylaxis has been given as a matter of routine to those men who admit having risked infection. The system employed has been efficacious and has undoubtedly served to prevent many cases of disease. During the period of February 1 to 4, while at Callao, Peru, venereal prophylactic treat ment was given to 737 men. Diseases resulting from these exposures were confined to 11 cases of gonococcus infection of urethra and two' cases of chancroid. During the period from February 10. 1921, to February 22. 1921, while at Balboa, Canal Zone, 472 prophylactic treatments were given, with no venereal diseases resulting from these exposures. Conditions on the Pacific coast are found to be less favorable for the effective ness of venereal prophylaxis, and the admission rate has been high during the time that the ship has been based at San Pedro. Calif. No. 1. 175 HEALTH CONDITIONS OF THE NAVY. ABSTRACTS FROM THK ANNUAL SANITARY REPOR T, UNITED STATES SUBMARINE BASE. NAVAL OPERATING BASE, HAMPTON ROADS, V.\.. FUR THE YEAR 1921. Living conditions on a submarine are apparently far from healthful. In ventilating a submarine during surface runs there are many fluctuations in the atmospheric conditions within the boat, the rapid changes of air causing drafts of cold air to enter a warmed space: on the other hand, during sub merged runs or runs in heavy weather, when hatches are closed, there is com plete stagnation of air in an overcrowded space. The older type submarine is poorly heated and when lying in cool water the temperature within the boat is always cold and damp. The air is saturated with water, and as a result the bedding and spare clothing become soggy, cold, and damp. Facilities for bathing are much curtailed. Men are living closely crowded together and have no opportunity for exercise other than what their duties in this small space provide. It would seem that living under conditions of this kind would be conducive to the development of respiratory and rheumatic affections of various kinds, but experience in this division of submarines shows that men serving on submarines are not more subject to such diseases than men doing duty at Hie Hampton Roads Base. Most of the men are young, only a few of the chief l*tty officers being in the neighborhood of middle' age. This Is undoubtedly another example of how young men, kept in good physical condition, may be made to stand adverse conditions and is no argument whatever for minimizing 'lie disadvantages nnd discomforts of such living conditions. ABSTRACTS FROM THE ANNUAL SANITARY REPORT. U. S. S. " MONOCACY," FOR THE YEAR 1921. The incidence of venereal disease for the year was very high, there being admitted to the sick list 13 cases of gonococcus infection of the urethra, 13 '•ases of chancroid, and 3 cases of syphilis. Thirteen of these 29 cases occurred during the month of June. It is believed that the entire crew appreciates the seriousness of the venereal diseases, for they have been given frequent indi vidual instruction as to consequences of such diseases. A prophylactic station lias always been accessible, and the men have been Instructed in the proper method of taking prophylaxis. After having been in the upper part of the Yangtze River for the entire winter, the Monocacy returned to Shanghai in June, where liberty was given freely to the men. The 13 cases of venereal disease for that month does not prove that the men had failed to receive the proper instructions :!iid warnings against the dangers of venereal disease, but rather that they ■iail disregarded them. Shanghai is overrun with houses of prostitution; the number of Chinese, Japanese, Russian, and European prostitutes is very high and no attempt is made to cleanse the city of this terrible vice. The " houses " usually frequented by sailors are along the water fronts. In localities where filth and disease are prominent and where the men have free and easy access lo an unlimited quantity of intoxicating liquors. The latter, I believe, is in a large measure responsible for the high incidence of venereal disease on the Asiatic Station. Many men have told me that when they went ashore they "ere determined to abstain from illicit intercourse, but that after having con sumed " liquor " they did not realize what they were doing. Under the influ ence of intoxicating liquors they would thus become easy victims of this large army of prostitutes. 176 Vol. XVII. HEALTH CONDITIONS OF THE NAVY. In the smaller ports up the Yangtze River there are fewer prostitutes and no all-night liberty is granted, and, as a result, there Is a lower incidence of venereal disease. All these facts will explain why the venereal report for June was so very high. I believe that the number of cases of venereal disease would be greatly diminished if the Navy Department would return to its former cus tom of allowing the men to furnish themselves with prophylactic tubes such as the Royal Navy issues to their sailors. Certainly such a custom could not do any harm, for as long as houses of prostitution are tolerated and whisky is easily obtained men will respond to their sexual desires. The Yangtze River ports lack recreation centers and clubs; there is no mental diversion for the men when they go ashore, and there is nothing with which they can advan tageously occupy themselves. I am not attempting to uphold the men or offer any apologies for their misconduct; I am merely stating facts —facts of which all medical officers on this station are fully cognizant.

Bunker, Lieutenant Commander. Medical Corps, United States Navy. The chemical analysis of the blood has attained a clinical simplic ity and significance that demands recognition. It provides points of value in diagnosis, prognosis, and treatment, and is especially use ful in nephritis, diabetes, acidosis, comatose conditions, gout, and in questions of kidney function and treatment, especially dietetic. Few diseases have been as j7et studied thoroughly in this respect, but our fund of knowledge is receiving constant additions. The field of tropical medicine is practically untouched, and it is quite possible that an investigation along this line might there yield facts of inter est and value. Some naval medical officers have access to such ma terial, and the time is ripe for the endeavor. Numerous articles relative to this subject have appeared in medical literature during the past few years. Most, however, have been in So. 2. BUNKER—CHEMICAL ANALYSIS OF THE BLOOD. 203 journals to which the average naval medical officer does not have access. So it is the intent of this brief summary to emphasize the clinical advantages to be obtained by examinations along this line, and to touch in a general manner upon the significance of findings. I have considered acidosis in a previous article, and will endeavor to do the same for kidney function later. No exhaustive consideration will be attempted, nor will matters of technique be considered. For those who desire such elaboration or details, I would suggest two hooks —" Practical Chemical Analysis of Blood," by V. C. Myers (C. V. Mosby Co., St. Louis, 1921), and "Practical Bacteriology, Blood Work, and Parasitology," by E. R. Stitt (P. Blakiston's Son & Co., Philadelphia). The former considers the question of sig nificance very satisfactorily, and the two works supplement one an other very nicely as regards methods. Current literature must be consulted for advances. One must not anticipate the solution of all his difficulties when the sample of blood is sent to the laboratory. Very few matters are entirely settled there. Abnormal findings relate to the patient, but not necessarily to the disease under consideration. The malarial parasite found in the blood smear establishes malaria, but does not eliminate other concurrent disease, perhaps rheumatic fever. Simi larly, a marked nitrogen retention in the blood would be strongly suggestive of uremia in a case of coma, but would not exclude cere bral concussion as the cause. It is for the clinician in charge of the patient to consider the blood chemistry report just as he does that of examination of urine, feces, cerebrospinal fluid, etc., and to deter mine its possible significance in view of the other evidence present. And it is also well to bear in mind that nephritis is a common com plication, especially in chronic conditions, and will itself affect the blood picture. The peculiar advantage of examination of the chemical con stituents of the blood lies in the fact that we thus pass behind the barrier of the kidneys. Findings in urine are always dependent upon the renal function. The kidneys normally excrete but traces of certain substances, e. g., cholesterin, fats, proteins, sugar, etc. Others, such as urea, uric acid, creatinine, chlorides, etc., are con centrated in the urine from the blood with varying facility. The kidney is said to have a certain threshold value for certain sub stances, i. e., they must be present in the blood stream in a certain concentration before they can be excreted in the urine either at all or in abnormal amounts. Thus, for sugar, there normally must be more than 160 to 180 milligrams per 100 mils of blood before gly- curesis occurs; no chlorides are excreted unless the blood plasma 108165—22 2 204 BUNKER—CHEMICAL ANALYSIS OF THE BLOOD. Vol. XVII. contains 562 milligrams chlorides per 100 mils. Kidney function, may be impaired, a situation in which there is not necessarily any parallelism between the effect upon the excretion of different sub stances. The function for chlorides, for instance, is independent of that for urea. Such an impaired function could cause our being led widely astray by urine examination alone. It is not unusual for diabetes mellitus with a blood sugar of treble the normal to show no glycuresis; there is upon record a patient who had 1,100 milli- grames sugar per 100 mils blood and only 0.5 per cent sugar in the urine. The net result, then, of our blood chemistry is a more intimate picture of metabolism. We can study substances that are not avail able in the urine. Early metabolic changes are detected, as well as the first disturbances of renal function. Abnormal concentrations of constituents may arise on the one hand from overproduction, defective assimilation, or retention, or, on the other hand, from decreased production or depletion as the result of excessive excretion or assimilation. Consequently, the findings in the urine are natu rally complementary to those in the blood, and their joint considera tion quickly settles the bearing of kidney function on the latter. Alone the urine is a very unsafe index of conditions beyond the genitourinary tract. Our chemical examination is directed toward many substances, which are conveniently grouped as nitrogenous and nonnitrogenous. Enzymes are also studied, especially diastase. The following list includes the constituents most frequently under consideration, as well as normal values for adults. These are expressed in the usual terminology of milligrams per 100 mils of whole blood unless other wise noted. Values elsewhere in this article will also follow the same system. Normally, total solids are 19-23 per cent, and total nitrogen is 2.7-3.5 per cent (0.6-1.1 per cent in plasma). Nitrogenous : Proteins — Hemoglobin 14 per cent by weight. Serum albumin 4. 5 per cent. Paraglobulin 3 per cent. Fibrinogen 0. 4 per cent. Nonproteins— Urea 20-30 milligrams per 100 mils of whole blood (10-15 for urea nitrogen). Uric acid 2-3 milligrams per 100 mils of whole blood. Creatinine 1-2 milligrams per 100 mils of whole blood. Creatine 3-5 milligrams per 100 mils of whole blood. Amino acids 6-8 milligrams per 100 mils of whole blood (constituent nitrogen only). Ammonia about 0. 1 milligram per 100 mils of whole blood. Bile pigments. No. 2. 205 BUNKER—CHEMICAL ANALYSIS OF THE BLOOD. Nonnltrogenous : Sugar 90-120 milligrams per 100 mils of whole blood. Chlorides 450-500 milligrams per 100 mils of whole blood (570-620 for plasma). Bicarbonate 53-77 vol. per cent C02 (plasma). Oxygen 18. 5 vol. per cent (oxygen capacity). Carbon dioxide about 40 nun. tension in arterial blood. Fat about 600 (Bloor's fat method). Cholesterin 170-250 milligrams per 100 mils of whole blood (Bloor's method). Lecithin (Bloor's " lecithin ")__ 3o milligrams per 100 mils of whole blood 122 for plasma). Acetone bodies 0-4 milligrams per 100 mils of whole blood. Calcium 5. 3-6. 8 milligrams per 100 mils of whole blood (7. 2-12. 1 for serum or plasma). Magnesium 2. 3-4 milligrams per 100 mils of whole blood (1. 6-3. 5 for serum). Potassium 153-240 milligrams per 100 mils of whole blood ( 18-21 for serum ) . Sodium 170-225 milligrams per 100 mils of whole blood. Phosphorus (total, as H«P04) — about 120 milligrams per 100 mils of whole blood (35-40 for plasma). Phosphorus (of inorganic phos phates) : 1-3.5 (serum). Sulphur (of sulphates) 0.5-1 milligrams per 100 mils of whole blood. This rather lengthy list, however, is of more theoretical than prac tical interest at present. C linically, we desire only that which helps us in our problems. The routine examination, then, confines itself usually to nonprotein nitrogen, urea nitrogen, uric acid, creatinine, sugar, and chlorides of whole blood, and plasma bicarbonate. There might be added cholesterin and oxygen capacity, the latter being a measure of the hemoglobin. Two technicians can complete about six such routine examinations in an ordinary working day. And I wish to reiterate that the technique is not complicated, usually being quite simple and within the capacity of an intelligent hospital corpsman. Moreover, the new test case has been equipped with these methods in view. Phosphorus and calcium are receiving considerable attention in connection with pediatrics. As time progresses others on the list may assume definite clinical importance and be generally useful, providing a simple technique for estimation is available. Whole blood, plasma, corpuscles, and serum have each been studied, as the list would indi cate. And I might mention that volume relations are being scruti nized —the effects of increased or decreased blood volume upon con centrations of constituents, as well as the relation of such concentra 206 BUNKER CHEMICAL ANALYSIS OF THE BLOOD. Vol. XVII. tions to variation in corpuscle volume relative to the plasma. In fact, the antipyretic effect of such drugs as sodium salicylate, aspirin, anti- pyrin, quinine, etc., is considered to be the result of the mobilization of sugar in the blood and the consequent general blood dilution. I have found that the meaning of " nonprotein nitrogen '' is not clear to some. It simply signifies, as the name would indicate, all nitrogen except that from the proteins. The nitrogen of the blood is in the proteins (serum albumin, hemoglobin, corpuscles, etc.) and also as a nonprotein portion. The list above shows that the non protein nitrogen would then be the nitrogen from the urea, uric acid, creatinine, creatine, amino acids, etc. It amounts to 25 to 30 milli grams per 100 mils of whole blood, while the total nitrogen is about 3,000. The nonprotein nitrogen is at present especially important clinically, and our chemical examination uses it, precipitating and discarding the protein portion. It is well to bear in mind that urea is largely exogenous in origin, and subject to considerable variation as the result of food. TTrie acid comes about equally from exogenous and endogenous sources; a high concentration in the blood is usually due to decreased elimination. Creatinine is almost entirely endoge nous. For the nonprotein nitrogen 30 to 35 milligrams per 100 mils of whole blood is considered a slight, 35 to 50 a considerable, and 50 to 100 a great increase, and uremia may be expected with values as high as the last. With advanced retention the urea nitrogen may be 75 per cent of the nonprotein nitrogen. The following table (amplified from Myers) is a concise summary of normal findings and those encountered in various clinical condi tions. In general, the blank spaces indicate normal findings, although in a few they ma}' mean no data. The diagnostic significance is evi dent. Some of the results are based upon the analysis of man}- cases, others upon but few. The values are in the terms already noted above, except those for diastatic activity (recorded in Winslow's empirical units) and acidosis (expressed in terms of plasma carbon- dioxide combining power—volumes per cent carbon dioxide—follow ing Van Slyke).

The table gives definite values, but it is worth while for the person analyzing a report to endeavor to determine how much any variation from normal is due to such factors as food, increased metabolism, defective assimilation, retention by a kidney whose function is impaired, etc. Nephritis produces blood changes essentially by reason of the usual inability to properly excrete the waste products of metabolism. Acidosis, edema, or uremia are the clinical evidences of such reten tion. Interstitial nephritis is characterized by the retention of nitro gen, the first changes being noted in the uric acid. Urea and non protein nitrogen increase later. The significance of albumin in traces and occasional casts in urine has been more definitely estab lished by examination for increase of uric acid in the blood — an increase arguing for an organic lesion. On a high purine diet there will be an accumulation of uric acid, a result that does not occur in 208 BUNKER—CHEMICAL ANALYSIS OF THE BLOOD. Vol. XVII. normal persons. Inasmuch as the urea furnishes such a large por tion of the nonprotein nitrogen and varies so markedly by reason of diet, a high nitrogen value affords definite information only if the intake is known. The nonprotein nitrogen has, however, always a negative value. Associated cardiac decompensation will further increase the blood urea. Values of over 4 for creatinine do not occur without great impairment of renal function, and findings of more than 5 have practically uniformly foretold a fatal termination in less than six months, except in acute nephritis and mild bichloride- of-mercury poisoning. The creatinine is also the best guide to the status of renal function in terminal cases. Parenchymatous nephritis shows relatively little nitrogen reten tion, but does evidence a decided tendency toward chloride retention. Low urea values, due to superpermeability of the kidney, are found occasionally with chronic diffuse nephritis and in hypersensitive cardio-vascular disease. The imminence of uremia may be judged by the extent of the nitrogen retention. We have an aid in the differentiation of the uremia of nephritis accompanied by a flagging heart from the passive congestion of cardiac decompensation, especially as to which is the secondary condition, and thus therapeutic indications relative to mooted questions of treatment, such as hot packs, morphine, renal stimulants, etc. Unsuspected cases of nephritis showing only gastric symptoms subjectively have been detected by blood chemistry. Essential hypertonia, with its normal blood chemistry, is differ entiated from arteriosclerosis with its frequent nitrogen retention. It is of interest to note that experimental administration of choles- terin has caused histologic changes in the aorta. The important questions of acidosis and kidney function, as already stated, will not be considered in this paper, although the former is an integral part of blood chemistry and the latter is an important factor in determining the blood picture. Their discus sion requires considerable space, and it is probably preferable to con sider them separately, while bearing in mind their relation to the chemistry of the blood. The surgeon is especially concerned with them if he desires the best results and uneventful convalescence. The pediatrician should always bear acidosis in mind. The blood may indicate a prediabetic state, and place the practi tioner upon his guard. Nephritis may be present with diabetes mellitus, and usually is when the latter is severe, so one must be pre pared for the blood picture of the former. The blood sugar and plasma C02 are usually considered the only safe guides in the treat ment of diabetes mellitus, and no extended medical or surgical inter ference should ever be attempted without their estimation. Glyco No. 2. BVXKER CHEMICAL ANALYSIS OF THE BLOOD. 209 suria is a poor guide, especially in advanced cases, as is readily in ferred from the remarks relative to renal function in the early part of the paper. A persistently low blood sugar is extremely favorable. A high threshold for sugar in a mild case on diet usually indicates some complication, such as arterial hypertension. A rising or per sistently high threshold for sugar despite diet is serious. Blood fats are considered by some to be a better index of the patient's condition than the blood sugar, but their estimation is by no means simple. The cholesterin determination is not difficult, and this compound is said to parallel and be an index of the fats. Some diagnostic significance is attached to the sugar tolerance text. There is some variation in methods for its application, and the following may be considered as good as any. After an overnight fast, ingest 100 grams glucose dissolved in 300 mils black coffee. Collect blood samples just before feeding and at 45 and 120 minutes after same, and determine the blood sugar in each sample. If the blood sugar has not by then returned to about normal, one may test further samples taken at hourly intervals. The urine may also be collected and tested for sugar. Under such conditions a normal person will show no glycuresis, and his blood sugar will be at its maximum (about 150) after 45 minutes, and approximately normal at the end of 120 minutes. The usual abnormal variation consists in increased height, or, especially, duration of curve before reaching normal, as much as six hours being not unusual. Until the significance of the test is more fully estab lished, it will probably be better to interpret such an abnormal curve as indicating an impaired sugar tolerance and its degree. Practi cally equivalent results are obtained in such diverse conditions as diabetes mellitus, nephritis, hyperendocrine (thyroid and hypo physeal) conditions, tuberculosis, epithelioma, pregnancy, fatigue, etc. There is a condition but recently recognized in which there is a normal blood sugar, a persistent glycuresis of usually less than 1 per cent and independent of carbohydrate intake, occasionally polyuria, but with no other symptoms of diabetes mellitus. It is known as renal diabetes, is apparently harmless, probably not uncommon, and may comprise most of those " diabetics " who can disregard diet with impunity. Fumnculosis often shows an increased blood sugar, and diabetic restriction of sugar may be of much aid in its treatment. In comatose conditions, nitrogen retention will select the uremic and hyperglycemia the diabetic cases. But acute nephritis should always be borne in mind, as it may have a pronounced acidosis but no nitrogen retention. 210 BUNKER CHEMICAL ANALYSIS OF THE BLOOD. Vol. XVII. The frequent hyperglycemia of hyperthyroidism is useful in dif ferentiating the irritable heart. The solitary increase of blood uric acid (probably the result of re tention) in gout aids in the differential diagnosis from simple rheu matic fevers and other arthritides, any uric acid retention in them being usually accompanied by retention of other nitrogenous ele ments. It is especially useful in the diagnosis of gouty arthritis without tophi. Of course this increase of uric acid alone is also characteristic of early interstitial nephritis, but, with the latter, a general nitrogen retention usually supervenes and there is commonly albuminuria and cylinduria. The amount of uric acid in the blood bears no relation to the severity or the chronicity of gout. A purine- free diet tends to lower the uric acid. This can be accomplished more effectively, however, by drugs, such as tolysin (neocincophen) or cincophen (Acidum phenylcinchoninicum). These increase the excretion of uric acid, and will also reduce increased blood urea or chlorides. They act as renal stimulants, and this excretory action is rapidly secured (that for tolysin reaches its maximum in about one day) and gradually lost. They apparently are not toxic, and are analgesic, the latter effect being gradually lost. Ten grams of sodium chloride by mouth in a glass of water is said to decrease blood chlorides if the gastric secretions are normal. If the secretory disturbances are marked, an increase in blood chlorides may be expec ted. Pregnancy is accompanied by low values for blood urea, and cholesterin is said to increase beginning with the fourth month and progressing to term. An increase in blood uric acid is definitely as sociated with the toxemias of pregnancy, and should place the obstetrician upon his guard. Diet is concerned particularly with retention, especially of nitro gen and chlorides, and defective assimilation, especially of sugar. The blood examination definitely settles such questions, and it should precede and then guide dietetic treatment. The efficacy of treatment will, in general, be shown by the degree of approach to normal blood findings. As a general rule, it is preferable to determine the chlo rides of whole blood rather than of plasma. Plasma, if used, should quickly be separated from the corpuscles. It is appropriate to mention here the ferment, diastase. This is an amylolytic enzyme whose activity is considered to be normally under the inhibitory control of the internal secretion of the pancreas, and whose function is concerned with the production of the blood sugar from the glycogen of the body. It is found in the body fluids and excretions. An impaired kidney function may cause its retention in the blood, and thus be the etiological factor in the hyperglycemia of such cases. Its diagnostic significance is still debatable, but very No. 2. 211 CHAMBEKS THE WEIL-FELIX KEACTION. high values, especially in the blood and with no evidence of impaired kidney function, should be considered confirmatory of impaired pan creatic function. For a complete examination one should secure at least 10 mils of blood, and it is best taken Z\ hours after a meal, preferably be fore breakfast. The values obtained from the sample taken after the shorter interval are probably satisfactory for clinical purposes. Truer values require the longer interval. Hammett found no prac tical difference between samples secured after fasts of 14 or Si hours. The sugar was variable, while the nonprotein nitrogen, urea, and uric acid were slightly lower after the longer interval. Plasma sugar concentration is not affected by ingestion of water. A rich carbo hydrate meal causes a slight increase of sugar that may last for several hours. . A protein meal causes a temporary increase of non protein nitrogen and amino-acid nitrogen. Fifty grams of protein, eaten by a normal person, produces an increase in urea nitrogen for 8 or more hours, the blood sugar being unaffected. With severe diabetes mellitus or nephritis the increase in urea nitrogen is more marked and sugar is increased, although the latter effect may be overlooked in the presence of a marked hyperglycemia. The values for many of the blood constituents will decrease the longer the sample stands. Twenty hours at room temperature does not change the nitrogenous substances, and the sugar only slightly. The sugar then deteriorates rapidly, especially when the sample is agitated. The other ingredients show but little change for two or three day's, especially if preserved as blood filtrate and in the re frigerator. THE WEIL-FELIX REACTION. By J. H. Chambers, Lieutenant, Medical Corps, United States Navy. The Weil-Felix reaction has gradually come into general use within the past few years as a laboratory diagnostic measure in typhus fever. It is an agglutination reaction, employing the patient's serum and a member of the Proteus group of microorganisms. The particular organism employed is known as X19, and was isolated by Weil from the urine of a patient suffering from typhus fever. From experimental evidence it is not believed that the Proteus organism has any causative relation to the disease, nor is it apparently a secondary invader in the ordinary sense. It is, however, very often present in the urine of tjTphus patients, particularly in the later stages of the infection. The strain used in the test has the usual characteristics of members of the Proteus group that ferment glu cose and saccharose, but do not ferment lactose, maltose, or mannite. Another organism having cultural characteristics similar to those 212 Vol. XVII. CHAMBERS —THE WEIL-FELIX REACTION. of Xl9 is known as X2 and is frequently used along with X19 as a confirmatory test. It has recently become apparent that Xl9 gives uniform and consistent results and is now commonly used alone. Sufficient work has been done in typhus centers to demonstrate conclusively that a positive reaction occurs only in serum obtained from typhus patients and not from other diseases. Napier (1) reports results on a number of cases of typhus, including 40 with mild attacks, and all of these gave a positive reaction. The highest titer was 1 :20,000 on the eighth day, the lowest 1 :200 on the eighth day, rising to 1 :10.000 on the sixteenth day. The average titer of the 40 cases was 1 :2,600, and was present on the seventh to the thirtieth day. Eleven cases clinically doubtful at the onset gave positive Weil-Felix reactions. The highest titer in this group was 1:20,000; the lowest 1 :50 on the fifth day, rising to 1 :800 on the seventh day. Two groups of control . cases were used, one of 50 refugees with no record of treatment in the hospital, and the other of 24 patients suffering from febrile conditions incompatible with a diagnosis of typhus. Of the first control group, one gave a titer of 1 :100, four 1 :50. Of the second group, two gave a titer of 1 :100, eight 1 :50. In the latter group, if cases of typhoid were excluded, none gave a titer of 1 :100, and only five of 1 :50. He concludes that eight per t ent of normals give a titer of 1 :50, and 25 per cent of febrile con ditions, other than typhus or typhoid, give a titer of 1 :50. Hence a positive Weil-Felix reaction must show a titer greater than 1 :50. Of his 59 cases, only 12 failed to give a titer above 1 :1,600, and none below 1 :640. Of the 77 control cases, none gave a titer above 1 :400, and only one that high. In Fairley's report (2) of cases in Egypt, 63 of 65 showed a positive reaction. Of the 120 cases other than typhus, none were positive in dilution of 1:20. Felix and Weil (3) reported positive reactions in 125 of their 126 cases. Of 632 patients not having typhus, including typhoid, meningitis, and relapsing fever, 12 per cent gave agglutination as high as 1 :25, with the agglutination incomplete or delayed. Sacquepee and Delavergne (4) report the Weil-Felix reaction constantly positive in typhus fever and negative in 14 cases other than typhus. Montefusco (5) reports reaction posi tive with a titer of 1 :800 in all but one of 100 cases, and constantly negative in a large number of acute diseases other than typhus, except one case of smallpox. Compton (6) reports 47 tests on 14 cases in Syria, with all but one case positive. Numerous other writers have reported series of positive results in typhus, and negative results in other diseases. Kraus and de la Barrera (7) reported positive results in all cases of typhus fever, with two positive reactions in other diseases. One of the latter was a case of typhoid (Widal, 1 :4,000, agglutination X19 1 :10.000) who had lived in Russia till a few years previously, and the other, a case of measles, with a history No. 2. 213 CHAMBERS THE WEIL-FELIX REACTION. of previous residence in an endemic focus of typhus, whose serum gave a titer of 1 :'20O. The authors termed these " anamestic reac tions." The exact technique of the test varies with the individual. Kesults obtained by using live or killed suspensions seemed to be equally satisfactory: and inasmuch as killed suspensions are more con venient, they were used in the majority of tests reported below. Cultures of X2 and Xl9 were obtained through the courtesy of Dr. G. W. McCoy and Miss I. A. I5engtson. of the Hygienic Labora tory of the United States Public Health Service. Twenty-four hour agar cultures were washed into normal salt solution containing 0.3 per cent formalin and kept in the refrigerator for four days, by which time all organisms were killed. This suspension was stand ardized to make a 0.1 per cent suspension of each strain. One cubic centimeter of this suspension was added to an equal amount of diluted serum, each serum being tested against both organisms and each series of tests having the usual control of salt solution. Living cultures in broth were used in 20 tests and living organisms in salt solution in 25. The results differed in no way from those obtained with killed organisms. Sera for these tests were obtained from patients in the naval hospital. Washington. D. C, on whom complement fixation tests for syphilis were being done. About 14 per cent of these gave a posi tive complement fixation reaction and the remainder included a wide variety of diagnoses. The serum, which was kept in the refriger ator, was always used within 24 hours after withdrawal. Four dilu tions, ranging from 1:16 to 1:128, were used for both organisms. After thorough shaking the tubes were placed in an incubator at 37° C. and readings made at the end of three hours. A final read ing was made on the following morning, and in no instance was there any change in the reaction. Of 370 sera examined, only one showed an agglutination in any dilution. In this case agglutination was present in a dilution of 1 : 128. In another test on fresh serum of the same patient agglutination was complete up to 1 : 160, whereas it was present but incomplete at 1:320 with X2 and Xl9. This is in accord with results obtained elsewhere. Much of the work hith erto reported has been done on individuals coming from or residing in districts where typhus is endemic and epidemic, whereas the majority of the patients seen here had never been exposed to typhus, and this may well explain the greater frequency of agglutinations in the low dilutions reported elsewhere. The one patient showing agglutination was a native of Denmark, had been in the merchant marine for eight years, and in the United States Navy for a number of years, so might very well show a mild form of the happily termed "anamnestic reaction" of Kraus and de la Barrera (7). 214 Til. XVII. NEL'BERGER .AVIATION MEDICINE. This additional evidence is added to the already lengthy series of tests showing a negative reaction with diseases other than typhus. All the patients examined here had received vaccine as prophylaxis against typhoid and paratyphoid within the past five years, the majority within three years and a few cases very recently. The immunity thus acquired did not seem to influence the Weil-Felix reaction in any way. As the titer of typhus serum is not very high prior to the fifth or sixth day, and a diagnosis on clinical findings alone is then often quite definite, the test is not needed in such cases. However, in the large group of atypical or doubtful cases, it is of much practical value, particularly in the diagnosis of the early cases of an epidemic. Here, it is in the first cases that the diagnosis is most often missed till late and it is then that the most effective preventive measures may be instituted. Conclusions.— (1) The reaction is negative in diseases other than typhus; (2) it is not influenced by serum showing positive com plement fixation test; (3) it is not influenced by typhoid prophy laxis.

AVIATION MEDICINE IN THE UNITED STATES NAVY. By J. P. Nki bkkuer, Lieutenant, Medical Corps, United States Navy. THE FLIGHT SURGEON. The British, French, and Italians, all stated early in the war that it was fortunate that the air forces of the United States were profit ing by the mistakes of the allied flying forces, and in recognizing at the beginning the fact that the medical problem of aviation is a very special problem and can not possibly be conducted except by medical officers specially trained for this sort of work (1). The British were the first to recognize the advantage of medical officers specially NO. 2. 215 NEUBERGER AVIATION MEDICINE. trained for aviation. During the first year of the war, 2 per cent of air casualties were caused by the Germans, 8 per cent were due to defective planes, and 90 per cent were due to physical defects of pilots. As soon as they had established an independent air medical service and specialized in the care of the flier, statistics changed im mediately and in the next year the 90 per cent was reduced to 20 per cent and in the following year to 12 per cent. When the United States entered the war, it was decided to follow in the footsteps of our Allies and medical officers with special qualifi cations for aviation duty were selected. At that time we knew very little about the medical problems of aviation, and in order to prop erly investigate these problems the United States Army established a research laboratory in Mineola, Long Island, N. Y. The labora tory was subdivided into seven professional departments, and each department studied the problems of aviation that concerned its own particular field. These departments were physiology, cardiovascular, ophthalmology, otology, psychology, psychiatry, and physics. This laboratory has produced wonderful results in this connection and the highest praise is due to the officers connected with it. A most im portant phase of their researches was the study of the effect of low oxygen on the circulation, respiration, mental reaction, and the eye. One of the early ingenious devices developed at the laboratory was a low-pressure tank with which it was possible to simulate air con ditions from sea level up to approximately 36,000 feet. Later a re- breathing machine was developed. With this apparatus the subject breathes the same air over and over again with the impurities elimi nated. The oxygen, of course, is constantly diminished, and the re sult is similar to that in the tank, for it was soon found that the im portant factor in altitude is the decrease in oxygen, the decrease of atmospheric pre&sure and temperature being of secondary considera tion. The primary duties of the medical officer assigned to aviation duty can be described under the headings : 1. The selection of the flier. 2. The maintenance of the fitness of the flier. The most important factor in the selection of the flier is the physi cal examination. One can not be too careful in this examination and should always carry the old rule in mind— " when in doubt, reject." This rule might work an injustice on an individual, but it will ultimately benefit the service as a whole and it certanly will save the lives of many men. The maintenance of the fitness of the flier is of equal importance to the physical examination. The aviator is subject to certain con ditions, which have a tendency to produce mental fatigue, which, if not discovered in time, will cause the aviator to deteriorate and make 216 Vol. XVII. NEUBERGER AVIATION MEDICINE. him useless for further service. This condition of mental fatigue is commonly spoken of as " staleness." It is in reality a functional degeneration of his mental and nervous system. After prolonged flying without a rest the aviator begins to do unusual things. He makes a bad landing. Perhaps he has a crash, or he hesitates to go into the air. He may completely lose his nerve. The aviation medical officer should watch the flying in order to see how pilots are withstanding the effects of flying, to take steps to combat at an early stage the onset of flying stress and to prevent undue fatigue. The term " Flight surgeon " is used in the United States Army to designate medical officers assigned to aviation activities. While this term is not used officially in the Navy, it simplifies matters to employ it in this article, as referring to medical officers of the United States Navy assigned to aviation duty. The flight surgeon in the United States Army officially receives training and instruction in actual flying in aircraft, which is not the case in the Navy. The Navy Department, however, has never voiced any objections to a medical officer taking flight, or instruction in actual flying, providing he can find an instructor at a station willing to give him flight in structions. The writer has found that all pilots realize the impor tance of the services of a medical officer on aviation stations and ap preciate the fact that he is looking after their health and safety. They are always more than willing to assist him in any way possible. The question should a medical officer of the United States Navy officially receive flight training? has been often discussed. The Army surgeons claim that in order to understand the medical prob lems of aviation, one must be a qualified flier. From the writer's personal experience, he has come to the conclusion that training in actual flying of aircraft is not essential, although it might be desir able, and that a medical officer, not a qualified pilot, can perform his duties just as well as though he had received actual training. It is, however, essential that he fly with the pilots as often as time and cir cumstances permit, in order to obtain first-hand knowledge as to the work the pilots have to perform, to experience the different air con ditions, to notice any changes in the human body in the air at high altitudes and in general, to have the same experience as a qualified pilot. It is believed that this experience can be obtained just as well by accompanying the flier as by oneself piloting the plane. The writer has taken numerous flights under all sorts of conditions and at the end of each flight he has found, on discussing different occur rences, that everyone had practically the same sensations, ideas, and opinions about all that happened while in the air. It is. of course, obvious that some men have keener powers of observation than others and notice things which others do not. The writer personally is not So. 2. 217 NEUBERGER — .AVIATION MEDICINE. in favor of making a doctor a " flier." He can not be expert in both. If the medical officer is a qualified aviator, it is necessary for him to spend a good deal of his time in the air in order to keep in practice and he develops the same peculiarities, attitude and symptoms as other pilots. He can no longer observe them in any one else, as prac tically all the symptoms of " staleness " are objective, and his useful ness as a flight surgeon is therefore at an end. He is just as likely to develop symptoms of staleness as any other flier without realizing it, for many pilots showing objective signs of this condition, yet un aware of it, protest most vigorously if the medical officer recommends a temporary " grounding," stating that they are perfectly all right and capable of flying, despite the fact that they show signs of com plete mental and nervous exhaustion. It is honestly believed that more can be accomplished and greater progress will be made in avia tion medicine if the, medical officer assigned to aviation duty is not a qualified aviator provided he takes sufficient interest in aviation, becomes engrossed in air problems, sees and experiences them himself in the air, either as an observer or passenger. "A medical officer assigned to aviation duty must have a thorough knowledge of internal medicine, including physiology and psychol ogy, and he must be able to make thorough eye and ear examina tions. It is believed that every flight surgeon should have special training in eye, ear, nose, and throat work." A medical officer as signed to aviation duty should be selected with as much care as the pilot. With deep and interested self-devotion to his work, he must be unselfish, approachable, gentlemanly, at the same time possessing firmness, and must have all other qualities expected of a medical officer, and, above all, he must not be afraid to fly. He must be " a pood mixer," and must obtain the implicit confidence of all pilots and should spend as much time as possible in informal association with them. He should make it a practice to be at the flight office as often as practicable and whenever the pilots " take the air." Half of the fliers are usually watching the others, and one can obtain a lot of valuable information from their remarks and general conversa tion. The flight surgeon should be a young man, about the same age or a little older than the fliers. He must work in close cooper ation with the instructors in order to gain as much information as possible about the student flier. He must be on the station whenever there are machines in the air, be it day or night, for when his serv ices are required they are certainly very badly needed. The flight surgeon must keep in touch with the flier's physical con dition and become acquainted with all affairs pertaining to him. He should spend as much time on the flying field as is possible, watch ing for defects in flying, such as bad take-offs, bad landings, uncer 218 Vol. XVII. NEUBERGER —AVIATION MEDICINE. tainties of action, and he should make it a point of seeing each flier every day, either on the fields, at mess, or in the quarters. At the United States naval air station on Rockaway Beach the commanding officer issued an order for all officers to have the midday meal at the bachelor officers' mess. This order at first brought forth a storm of protest, especially from the married officers who had quarters on the station or in the vicinity, as they preferred to have lunch with their families. However, they soon saw the benefit of the order and adjusted themselves to it. This order brought the officers together at least once a day and gave them an opportunity to know each other better and to discuss the different events of the day ; they obtained different viewpoints and oftentimes better under standing of a happening whether it was a successful maneuver or a fatal crash. The writer knows from personal experience that argu ments and scientific discussions during this meal hour resulted in many improvements, increased knowledge, better understanding, and the greater efficiency of all the flying personnel. It is considered an excellent procedure and recommended for all naval air stations. One of the most important duties of the flight surgeon is the repeated physical and mental examination of the aviator to deter mine his continued fitness for flying. Its accomplishment is not an easy task, as it inconveniences the pilot. The average pilot dislikes frequent physical examinations, because he is afraid that something may be found which would ultimately disqualify him physically from flying. It is quite hard for him to realize that this examina tion is carried on for his benefit and personal safety. The frequency of these examinations depends upon circumstances and the amount of flying carried on. It is believed, however, that this examination should be made at least once a month and an entry of the result should be made in the health record. In making this examination the possibility of staleness should always be borne in mind. The flight surgeon should always keep in intimate touch with the flight commander and the instructors, especially on stations used for training purposes. He should act in an advisory capacity to the flight commander, and by mutual cooperation many men may be discovered who a re for some reason not flying at their best. It is the flight surgeon's duty to see that all of the flying personnel have sufficient, proper, and suitable exercise. He should impress upon the fliers that they should regard themselves much in the light of athletes, and that they must bear in mind the rules for the train ing of athletes, such as temperance in all things, good hours and plenty of sleep, good food and comfortable quarters, and the right kind of recreation. It is believed that comfortable quarters for the aviator are just as necessary as a comfortable flying suit, as flying is accompanied by great mental and physical fatigue, and the No. 2. 219 NET'BERGER AVIATION MEDICINE. aviator should have a comfortable and pleasant place to rest after his work is done. The flight surgeon should organize the medical department of the air station so that all accidents may be handled quickly and efficiently. He should investigate every crash, to determine whether it was due to a physical or mental defect of the pilot. If the defect is of a tem porary nature, grounding should be recommended, but if the defect is permanent, the pilot should be disqualified for further flying. When in doubt the pilot should be kept under observation until his status is definitely determined. The flight surgeon must appreciate his work. There is no duty for the Navy medical officer of to-day in which there is more chance and opportunity for progressive research than that of the flight sur geon. It is a known fact that marked reduction in fatalities has occurred where efficient flight surgeons have been placed. While we can not reduce the incidence of accidents due to mechanical or struc tural defects, we certainly can reduce those due to the men themselves. A recent publication (2) of the United States Army Air Service on the subject of aviation states : " The value of the flight surgeon has been abundantly proved in the training schools of the United States and France; but the signing of the armistice prevented the full realization of the hope that flight surgeons would be placed where they are of the greatest value — at every aerodrome and balloon sta tion at the front. " It can readily be seen that a skillful flight surgeon would have been very valuable at the aerodrome where Guynemer had his head quarters. That marvelous flier had shown increasing nervousness and physical unfitness for some time. In his delightful book, Mr. Driggs says: 'A new Guynemer revealed himself to his friends and comrades. He became nervous, sick, and irritable. His comrades, unable to control their captain, telephoned to Paris, informing their old commanding officer, Brocard, that Guynemer was sick and in no condition to fly, and imploring him to come back to the aerodrome to take their captain away for a much-needed rest. He arrived about half an hour after Guynemer had left on his last flight.' " " Rickenbacker says: 'It is plainly imperative that one keeps one's self always fit and clear minded. It is a matter of life and death to every air fighter—this quick-thinking, unburdened mind.' His words in speaking of the fatal accident of Lieutenant Kurtz are very illuminating : ' I had noticed before starting that Lieutenant Kurtz appeared nervous, but did not give the matter any great considera tion. The explanation was given by a brother officer who had come with Lieutenant Kurtz to the squadron. Before starting on his last flight Lieutenant Kurtz had confided to him that he was subject; to 108165—22 3 220 Vol. XVII. RAYNOR —MEDICAL CORPS UNITS. fainting spells when exposed to high altitudes, and the only thing he was afraid of was that he might be seized with such a fit while in the air. Alas, his fear had been only too well founded. But what a pity it was he had not confided in me. his flight commander.' " After a flight of over 15,000 feet, Lieutenant Kurtz was making a turn over an adjoining field, when his Xieuport dropped into a vrille, crashed, and caught fire. Experience has shown over and over again that a flier will confide in his flight surgeon when he will be silent with his commanding officer." REFERENCES.

Raynob, Major, United States Marine Corps. ORGANIZATION OF THE DIVISION STAFF. In the preceding article we discussed in brief and general terms the organization of a brigade. Because the brigade, except when serving alone, is not an administrative unit, and, because the regi mental medical officers function directly under the division surgeon (when the brigade forms a part of a division) and should, there fore, have at least a working knowledge of the duties and functions of the latter in order that they may intelligently cooperate with him, it is believed that the next logical step is a description of the organi- 1 There has been established at the field officers' school, Marina Corps schools, Marine Barracks, Quantlco, Va., a correspondence course for medical officers which offers many advantages to medical officers of the Navy, particularly those serving with the Marine Corps in the field. The duties required of medical officers on board naval vessels and at shore stations in the United States are totally different from those required when serving with the Marine Corps in the field, where, during active operations, aid stnUons, dressing stntions, field and base hospitals must be established, and problems of evacuation must be solved. The staff problems connected with a military force in the field are complicated ones — much more so than those presented on board ship, and require a high degree of initiative on the part of all staff officers and in whom must be centered a great deal of responsi bility. The senior medical officer of any military organization is a technical advisor to his commanding officer, and upon him rests the responsibility for the coordination of all the medical units assigned to the command, their disposition to most effectively serve the combatant troops, and the procurement and issue of medical supplies in adequate quantities. To perform these duties most efficiently requires a more or less intimate knowledge of the organization of the combatant units ; their tactical dispositions under varying condi tions ; familiarity with the organization of the Medical Corps units best calculated to meet the demands made upon them ; and a knowledge of topography and tactics. In time of peace the only means available to the average officer for acquiring this knowledge lies in the solution of map problems. The general purpose of medico-military map problems is to invite attention to the varying conditions and factors which might .No. if. 221 BAYNOB — MEDICAL CORPS UNITS. zation and functions of the division general staff, and an outline of the administrative and technical services. A division consists of approximately 20,000 officers and men. Manifestly, it would be impossible for one man to control such a great number of individuals. For this reason we find these indi viduals organ:zed into a great number of subordinate groups, each having its own commander and varying in size from the squad of seven men under a corporal to the brigade, which is the largest sub ordinate unit in the division. It is by means of this organization that the commander, by dealing with a very few men, is enabled to exercise his authority over each individual in his command. This organization, by means of which a commander controls and directs the movements of his troops, is called the chain of command. The number of subordinates with which one man can deal effectively varies from five to nine, and it is upon this principle that military organization is largely based. Let us assume that a division has been directed by some higher authority to march from X and attack the enemy at Y. The first task of the division commander would be to draw up a plan for the movement. But before a plan can be formulated the commander must obtain as much information of the enemy as possible. The size of the enemy's force, its composition, disposition, condition, morale, probable intentions, etc., will all have a material influence on his plan. So also will it be influenced by the routes available and the nature of the terrain. In addition to the foregoing, he must study the question of supply in relation to the movement. He must deter mine and decide how much food and ammunition will be required, the kind and quantity of clothing and equipment to be carried, and innumerable other things that affect the fighting efficiency of the command. influence the management of the Medical Corps units serving with troops in the field. The correctness of the solutions rendered Is of relatively small Importance. Such solu tions merely apply to Individual concrete cases ; but the solution of a sufficient number of problems demonstrates broad general principles upon which the efficient solution of such problems or the handling of actual situations liable to be encountered in the field must depend. The practical value of map problems lies in the stimulation of thought along lines ordinarily relatively unfamiliar. Medical officers of the Navy are urged to take advantage of this opportunity. Further information regarding the course may be obtained from MaJ. S. N. Raynor, Marine Corps Schools, Quantico, Va. Officers enrolling for the course would be required to provide themselves with the fol lowing maps, which may be purchased from the book department, General Service Schools, Fort Leavenworth.

Having gathered together all the information obtainable, the com mander is then ready to draw up his plan, and after having done so to communicate it in the form of orders to his subordinates. These questions all relate to strategy and tactics, and naturally group themselves under the head of planning, directing, and coordi nating. In addition to his tactical and strategical functions, there are others of a more technical and administrative nature for which he is held responsible. Having decided that he will need so much am munition, food, clothing, equipage, etc., he must also take the nec essary measures to procure it. Such questions as the kinds and pro portions of the artillery ammunition to be carried must be decided. If the operation involves crossing a river where the bridges have been destroyed or are inadequate, he must determine and decide the kind and quantity of bridge material to be carried. Questions of signal communication, hospitalization and evacuation of men and animals, disposition of prisoners of war, traffic control, kinds and quantities of various materials for the construction of command posts, shelters, etc., must also be decided. These functions are all closely related, and are therefore placed in a group by themselves — a technical and administrative group. There are still other functions which group themselves into a purely administrative group. These functions, such as the assignment of officers and men to subordinate units, records of personnel, awards of merit, infractions of discipline, and many others of a like and routine matter, while they do not directly affect the tactical handling of the division, do affect its morale, its discipline, and its personnel, for all of which the commander is held directly responsible by his superiors in command. It is quite obvious that it would be beyond the powers of any one man to perform more than a very small proportion of the functions enumerated. He would become so involved in the mass of details as to preclude any possibility of his exercising his higher functions of command, viz., the study and consideration of questions affecting the tactical and strategical handling of his division, and upon which depends the success of his command as a combat unit. Evidently, if the division commander is to successfully carry out the tasks assigned his division, he must have competent and trust worthy assistants who are specialists in the various tasks assigned them. These assistants constitute the staff. While the duties of these staff officers pertain to the functions of command, they do not, as such, exercise command. Where orders are issued they are issued in the name of the commander, who alone is responsible for them and to whom falls the lot and right of making a decision. The staff No. 2. 223 RAYNOR —MEDICAL CORPS UNITS. z z F 1 8 G-2 00 O 5 d n tf 3 - •nj3ua J80UJO IBuSlg XaodniOD pra8is japuBtn joiaao aSsssojv laoujo jaUpnoH pas-o'W ■jpraoo'SuaVi - --f Bp •qsaow isoaojj pns jpiuoD bH ■03 bH 1 Li : c ■ a Si i 2 a I e o 224 Tol.

We have seen that the functions of the division commander are divided into three groups: First, that pertaining to command and called the planning, directing, and coordinating group; second, that pertaining to the technical arms and services, and called the techni cal and administrative group; and third, those pertaining to routine functions, and called the administrative group. This division of the functions forms the basis of staff organization. Officers assigned to the first group constitute the general staff ; those assigned to the second group the technical and administrative staff ; arid those to the third group, the administrative staff. We will now consider those three groups separately and in more or less detail in order that we may see the relationship that exists be tween them and the commander, with the troops, and between them selves. THE GENERAL STAFF. The general staff is the connecting link between the general and his command. It relieves him of the mass of detail and leaves him free to devote his attention to the higher functions of command; it furnishes him with the information necessary to reach a clear and correct decision ; works out tentative plans and the details thereof ; and gives expression to his decisions in the form of orders and in structions, and insures their execution. By referring back we will see that this group naturally divides itself into four sections —one having to do with information of the enemy; another with questions of supply as affecting strategy and tactics; another with administrative questions; and still another section which having received all the information required from the first two sections, and the commander having drawn up a tentative plan, works out the details of this plan and, when a decision has been reached, communicates that decision to the subordinate commanders in the form of an order. From this division of duties has evolved the four sections into which the general staff of the division is divided : To the second sec tion or G-2 appertains intelligence of the enemy ; to the fourth section or G—1, questions of supply; to the third section or G-3, the prepara tion of plans of operation and their promulgation in the form of field orders so that they may be intelligently executed; and to the first section or G-l , personnel and routine matters. In Armies and higher No. 2. 225 RAYNOK MEDICAL CORPS UNITS. headquarters, the G-3 section is again divided into a G-3 section and a G-5 section, the former being confined to operations and the latter responsible for questions of training. The volume of work required from each of these sections is such as to require considerable personnel, varying with the size of the com mand. The work of this personnel in each section is coordinated and controlled by the chief of that section. Each chief of a section is officially designated as assistant chief of staff G-l, G-2, G-3, or G^, depending upon the section to which assigned. Jn order that all parts of the staff may function smoothly and that all questions of differences of opinion may be settled, and that all may be coordinated into an efficient team, the four sections of the staff are placed under the command of the chief of staff, who is the mouth piece of the division commander and the officer through whom he communicates his decisions and wishes, and through whom he re ceives the information and tentative plans upon which he bases his decisions. It is not the purpose of this article to go into a detailed description of the organization, functions, and operations of the four sections of the general staff. Only a very general outline of their functions sufficient for a clear conception of the staff organization as an entity will be given. As a concrete example let us go back to the division which was ordered to march from X and attack the enemy at Y. The operations or G-3 section is the group which will plan and work out the details for the movements of the division. The commander may, through his chief of staff, submit to this section a general outline of how he wishes the movement to be carried out, or, he may simply transmit to it the instructions he had received from higher authority and direct it to draw up tentative plans for his approval. The chief of this section, before he can draw up any plan, must get in touch with the chief of the intelligence section (G-2) in order that he may familiarize him self with any new information concerning the enemy, for, as already stated, the strength and disposition of the enemy will, very naturally affect the formation of the division for the movement. If the enemy is near, the formation must be such as to facilitate early and rapid deployment. This might best be accomplished by an advance in several columns over parallel roads. On the other hand, the presence of a hostile force on one flank would necessitate a flank guard. The strength and composition of the advance guard would also be influ enced by the strength and disposition of the enemy. It is evident, therefore, that there must be the closest cooperation between the G-2 and G-3 sections. The same sort of relationship must also exist between G-3 and the supply (G-4) section. This latter section works out and plans 226 Vol. XVII. RAYNOR MEDICAL CORPS UNITS. the operations of the services. If there is not the most complete coordination between these two sections, confusion and the most se rious consequences are likely to result. Ammunition and food sup plies, without which an army is helpless, may fail at a critical moment. For example, G-3, in drawing up his plans for the attack, may wish to use smoke or gas on certain sections of the enemy's posi tion, or he may desire to put over a long and heavy bombardment. He should first ascertain from G-4 if this ammunition is procurable, for otherwise he may find out, when it is too late, that his plans were faulty because the ammunition he desired was not obtainable. Likewise, G-4 must obtain from G-3 the latter's plans in order that the field and administrative orders will not conflict with one another. If the division is to be deployed for action G-4 must know the relative position of the various organizations before he can determine and designate the distributing points for rations and the distributing stations for ammunition, as well as the numerous other details that go to make up the administrative order, and which are dependent on the field order. (Note. —The administrative order will be discussed in a subsequent article.) THE TECHNICAL AND ADMINISTRATIVE STAFF. It has been previously stated that the administrative (G-4) sec tion of the general staff directs and controls the operations of the technical and administrative staff. Before we go into the details of this latter group, let us examine for a moment the reason for this group of the staff. As a matter of principle every staff should be reduced to the minimum consistent with efficiency. What are. the functions of the technical and administrative staff? Day after day the 20,000 men of our division must be fed, which means that rations must be procured and delivered. Furthermore, they must be properly and adequately clothed and equipped at all times. During combat they must have a plentiful supply of ammu nition, which must be procured and distributed. Every day a large number of men are taken sick and require medical attention. Dur ing combat many become casualties through wounds or gas. Arms and equipment are constantly being lost, destroyed, or worn out, and must be replaced. Animals, like men, become casualties, and some must receive medical attention, while others must be evacuated and replaced. Constant communication must be maintained withan the division and with headquarters, and this requires the supply and installation of signal equipment, such as telephones, switch boards, wire, radio apparatus, flags, panels, pyrotechnics, etc. When marches are undertaken the road may be in need of repair or bridges may require strengthening or have to be replaced. To distribute the supplies we must have both horse and motor transportation, and KAYNOR— MEDICAL CORPS UNITS. 227 this transportation must be so regulated as not to cause congestion on the roads or interference with the troops, otherwise the supplies may fail to reach their destination in time to be of any value. It is quite evident that no one man could perform all of these multifarious duties. Moreover, many are of a technical nature and require technical knowledge and skill which no one man could ex pect to master. This, then, is the reason for the technical and admin istrative staff: the officers who compose it being specialists in the bran, hes they direct. These officers are the technical advisers of the general and his general staff, and while they ordinarily function un der the direction and control of the G—4 section, nevertheless, at times and for some purposes they may function under the direction of some of the other sections of the general staff. Within a division the staff officers forming the technical and ad ministrative staff, and functioning, as a general rule, under the G-4 section of the general staff, are as follows : Field Artillery brigade commander. Machine gun and howitzer officer. Air service commander. Signal officer. Engineer officer. The surgeon. Ordnance officer. Quartermaster. Tank commander. Chemical officer. With the exception of the duties of the surgeon, it is not believed necessary to go into details regarding the functions of these staff officers. The functions of the division surgeon will be the subject of the next article. THE ADMINISTRATIVE STAFF. If, as has already been shown, it is beyond the powers of one indi vidual to perform all the duties pertaining to the administrative and technical staff, it is equally impossible for any one individual to dispose of the innumerable details of routine administration which fall within the province of the administrative staff. These functions divide themselves naturally into certain classes which are clearly de fined and pertain to the routine administration of the division, its correspondence, records, statistics, finances, questions of personnel, and others of a like nature. There are other functions which con cern inspections, questions of morale, discipline, military justice, and spiritual welfare. 228 Vol. XVIJ. RAYNOE —MEDICAL CORPS UNITS. These duties, which constitute the functions of the administrative staff, are divided among the following staff officers : The adjutant. The inspector. The judge advocate. The chaplain. The postal officer. The finance officer. The headquarters commandant and provost marshal. In the channel of staff control and coordination these officers oper ate under the G-l section of the general staff. RELATION BETWEEN HIGHER AND LOWER STAFFS. In the foregoing discussion the staff organization of a division has been taken as a model. The staffs of all organizations are, however, organized on the same general principles. Although in principle each staff functions under the authority and in the name of its com mander, it will be found that in matters of a purely routine nature the higher and lower staffs deal more or less directly with each other. However, it should always be remembered that a staff officer, as such, can not exercise command except in his own office and over his own assistants. Before closing it seems to be advisable to define and illustrate the words coordination, supervision, and control, which are continually being used in reference to the general staff. Webster's Dictionary defines coordination as " The act of regulat ing and combining so as to produce harmonious results." Let us apply this definition to an example and assume for this purpose that the division which was to march from X to Y reaches the vicinity of the latter place late in the afternoon, and that the com mander decides to bivouac for the night and attack the enemy's position early the next morning. There are many questions of sup ply and administration which will conflict and produce confusion at this critical time unless there is some one in authority to make harmonious adjustments of these conflicting claims of the adminis trative and technical staff in the light of their bearing on the plan of the commander and which can not be known to them. There is the quartermaster who is responsible for feeding the troops; the ordnance officer who must see that all small-arms am munition needed for the battle on the following day reaches the troops in sufficient quantity and on time; the surgeon must make plans for the evacuation of the wounded and that necessitates the establishment of collecting stations, field hospitals, ambulance routes, etc. ; and the engineer and signal officers who must get supplies to the front. Each of these officers is. quite naturally, interested only in No. 2. 229 RAYNOB— MEDICAL CORPS UNITS. his own particular task. If some one does not pass upon and regu late their conflicting claims, the evening before the battle will find the road leading to the front blocked with traffic and, instead of all the supplies reaching their respective destination that night, traffic jams will probably prevent any of them from reaching their desti nations. In addition to the foregoing, the quartermaster has selected a point where he wishes to establish a ration distributing point, but it appears that the ordnance officer has selected that same point for establishing his ammunition distributing station; or that the sur geon wishes to establish a collecting station there; or that the engi neer officer would like to use that spot as a dump for engineer ma terial. Not one of these officers is in a position to decide as to who shall have priority because not one of them is familiar with the gen eral plans for the attack, and, even though they did know, each one would naturally decide in favor of his own service. There must be some one, other than these technical staff officers, to make harmo nious adjustment of these conflicting claims, so that no one particu lar class of supplies will reach its destination but that all of them will reach their destinations on time and without confusion. The officer best qualified to coordinate the activities of these officers of the administrative and technical staff, and to produce a harmonious and smooth working machine, is one who can view all of the func tions from the viewpoint of the commander — in other words, a mem ber of the general staff, and in the ease in question, the assistant chief of staff G-4. Control is defined as "To restrain, rule, govern, manage, guide." The assistant chief of staff G-4, having coordinated the conflicting claims of the technical and admisistrative staff, and having decided on such other matters of a supply and administrative nature as required direction and adjustment, governs, manages, or guides the operations of these services by the issuance of administrative orders and instructions to the command in the name of the division com mander. The mere issuance of orders is not sufficient, as we are all well aware. There must be a follow-up to see that the instructions and orders of the commander are carried out in accordance with his plans and wishes. This overseeing, inspection, superintendence, etc., con stitutes the general staff supervision. The accompanying chart shows graphically the organization of the general staff of a division.

GAS WARFARE. EFFECTS OF POISONOUS GASES—EARLY AND LATE.1 By Maj. W. R. Galwbv, O. B. E., M. C, Royal Army Medical Corps. Since the advent of chemical warfare a very large number of sub stances have been examined with a view to determining their suita bility from the points of view of production in quantity, use in shells, bombs, or projectors, and the physiological effects on human beings and other animals exposed to them. A detailed list of these substances would serve no useful purpose, and it will suffice to show how thej' may be grouped into the follow ing classes according to their physiological effects and to mention one or two of the more important substances in each group. (1) Lachrymators. (2) Sensory irritants of the eyes, nose, and upper respiratory passages. (3) Vesicants. (4) Asphyxiants or acute lung irritants. (5) Direct poisons of the nervous system. (6) Gases which act by interference with the respiratory property of the blood. Compound. Formula. Boiling point °C. Characteristics. Benzyl bromide.. . C«H(CU5Br 198 Colorless liquid with pungent smell. Group (1) Lachry mators. Xylyl bromide CH^HsCHjBr... CHjBrCOCH, 185 137 Brom. acetone Pale yellow liquid with pungent smell. (2) Sensory irritants of the eyes, nose, and upper respiratory passages. Examples: Di-phenyl. chlor. arsine (C6Hr,).,: AsCl melt ing point 43° C. ; boiling point 333° C. ; faintly odorous, yellowish oil or as a solid; ethyl-di-chlor. arsine, C2HsAsCl2< boiling point 156° C, faint ethereal smell. (3) Vesicants. Examples: Di-chlor. ethyl sulphide (mustard /CH CH CI gas) S<^ c^CH^Cl^0^11^ P0^'' a Pa*c yeH°wisft \ 2 2 odor of garlic or mustard. (4) Asphyxiants or acute lung irritants. Examples: Chlorine Cl2, boiling point 33° C, greenish-yellow gas, smell of bleaching 1 Reprinted from the Jour. Royal Army Med. Corps, London, February, 1922. No. 2. 231 GALWEY —GAS WARFARE. lime; phosgene (carbonyl-chloride) COCL, boiling point 8° C. ; col orless pas, smells of musty hay, tobacco gives a characteristic taste after phosgene has been inhaled. (o) Direct poisons of the nervous system. Example: Hydrocy anic acid HON. boiling point 26.5° C, melting point 13.8° C; color less mobile liquid with smell of bitter almonds. (6) Gases which act by interference with the respiratory proper ties of the blood. Example : Carbon-monoxide ; colorless, odorless gas, lighter than air. This classification is to some extent artificial, for in certain in stances the groups merge into each other, e. g., some lachrymators are asphyxiant in high concentrations and the asphyxiants cause lachrymation. Again, the arsine compounds besides being sternu- lators cause lesions in the lungs and possibly in the central nervous system. A8PHTXIANTS. Confined to the upper air passages these substances may reflexly inhibit breathing and may produce anesthesia of the mucous mem brane with loss of taste and smell. If they reach the larynx in quantity, they may cause immediate suffocation through spasm of the glottis. In the pulmonary air passages they may cause intense bronchial spasm, also necrosis and stripping of the mucous membrane leading to mechanical blocking of the air passages. If they reach the air cells in large quantities, they may penetrate the epithelium and the capillary walls and directly affect the blood, and so lead to those changes which bring about a blocking of the pulmonary circulation. Immediate death has occurred in laboratory animals exposed to high concentrations of phosgene. When this happens, intense ven ous and capillary congestion and subdural hemorrhages in the brain are found. The lungs show practically no edema. The blood ves sels in the lungs are much congested and inundated with a brownish granular material. The blood in the systematic circulation is nor mal to spectroscopic examinations. Death is thus accompanied by and probably due to an immediate pulmonary vascular stasis re sulting in acute asphyxia. Cats exposed to chlorine 1.700 died in less than 15 minutes, the blood being almost black, arterial pressure falling rapidly and there being no asphyxial rise, and practically no lung edema. Pulmonary changes appear to be a necessary stage in all the patho logical effects of the irritant gases. With doses of such a strength as to cause death in two hours, damage of the lung seems a neces sary factor. 232 Vol. XVII. GALWEY —iGAS WARFABK. In smaller quantities than those giving rise to effects just de scribed, the asphyxiants may injure in various degrees the bronchial mucous membrane and the epithelium of the air sacs and capillary walls, without actually penetrating into the capillary vessels, the lesions giving rise to intense pulmonary edema. Finally, a secondary bacterial infection may lead to pneumonia and infective inflammation of the respiratory passages. The condition brought about after the injury to the capillaries and air cells is one of want of oxygen, and to this most of the serious symptoms and the sequelae of asphyxiant gas poisoning are due. In fact, there is no good evidence that with moderate concentrations of gas, any system of the body other than the respiratory is pri marily damaged. So far as the evidence goes at present, the lesions found in the other organs are a consequence of the interference with the respiratory exchange of oxygen. Of the typical asphyxiants chlorine affects the upper air passages and bronchial tree primarily; while the action of phosgene is chiefly on the cells of the lung alveoli. Chlorpicrin is intermediate between the two. Experimenting with dogs, Underhill found that chlorine has a very strong irritative action, an animal gassed therewith becoming excited and in evident distress. With chlorpicrin the character of the reactions is very similar but less pronounced. With phosgene, on the other hand, the animals appeared to be in no immediate distress. To some extent this difference of reaction can be explained. When the substance is introduced in the atomized condition, if the spray is coarse it may be entirely held up in the upper respiratory passages. A fine spray, on the other hand, may reach the alveoli. If the sub stance is very soluble, as ammonia, the moisture of the surfaces of the air passages would largely entrap it. Possibly also a substance may be comparatively innocuous to the more resistant epithelium of the air passages, and only effective on the more delicate lining of the alveoli. Or again, the vapor may have an affinity for some tissues while it is relatively indifferent to others, as in the case of mustard gas, which attacks the epithelium of the air passages, but not that of alveoli. In acute deaths from asphyxiant gas poisoning, i. e.. those occur ring in about 24 hours, the most striking changes are found in the lungs. The following are the gross lesions found in human beings : On opening the thorax the lungs are voluminous, and hardly collapse at all. Distended lymphatics and small subpleural hemor rhages are visible on the surface. Rarely the hemorrhagic areas coalesce with stripping of the pleura. Xo. 2. 233 GALWEY — WARFARE. heavy doors loaded with irons and bolts, which were opened for us by armed mamelukes. Prescribed for the Bashaw's disorder. Feb. 6.—The Bashaw sent for me to come to his room in the castle. He shook hands with me. received me with much politeness, and requested me to pay every attention to his family ns a physician. Feb. 10. —The Bashaw gave the officers permission to walk out into the town and country, but not to visit the consuls nor the batteries. Our dragoman. Haniet. was ordered to walk with us and direct us where to go. We went out six at a time. , Feb. 16.— Prescribed for the Bashaw's eldest daughter. Her husband offered me many civilities. At 5 o'clock. P. M. were informed that two English mer chantmen were standing in for the harbour. They proved, however, to be two vessels under the command of Oapt. Decatur. About 11, at night, we were alarmed by a most hideous yelling and screaming from one end of the town to the other, and the firing of a cannon from the castle. On getting up and opening the window which faced the harbour, we saw the frigate Philadelphia in flames. Feb. 17. —The Turks appeared much disheartened at the loss of their frigate. A strong guard was put at our door, and we were forbid going out. I was forbid visiting our sick. It was reported that an American schooner and three boats set fire to the ship. Two Turks escaped who told this news. They said that eight Turks had charge of the ship, and they supposed the other six were carried off by the Americans. Our dragoman informed us that we were to be removed from our present habitation into the castle. Feb. IS.—A guard of about twenty Turks was at our door. I asked permis sion to visit our sick and was refused. A gloomy aspect continued on the faces of the inhabitants at the loss of the frigate. Feb. 19.—Again asked permission to visit our sick, and was again refused. Feb. 20.— Permitted to visit the sick. —-Pound the town full of country militia and our guard doubled. Feb. 21.—Our prison was kept full of Turks, to guard us. The Bashaw, having got a little over his fright, consented to let us remain where we were. Feb. 21.—We were forbid sending letters to our friends, without first show ing them to the Bashaw or his ministers. The last letters we received, were broken open by the latter, before they were delivered to us. March 1.—We were conducted to the castle. March 2.— Found our habitation very dark and smoky, having no light but what came through a grated sky light. March 3.—Not allowed to visit the sick, and our dragoman was forbid carry ing letters to use. March .}. —Captain Bainhridge received a letter from the ministers, repri manding him on account of three men who floated ashore a few days after the burning of the frigate. The Turks pretended that they were murdered after they were made prisoners by the Americans. March 6. —In close confinement. Hamet. our dragoman, was taken from us The Bashaw suspected him of being too friendly to us. March 7. —The Tripolitans got the guns from the remains of our frigate, and mounted them on their batteries. In trying them, several of the gun carriages 250 JONATHAN COWDERY, SURGEON IN U. S. NAVY. Vol. XVII. broke down, and one of the gun.-* hurst and killed one Turk and wounded four. March H. —The Turks seemed much alarmed, and placed a strong guard at our door, for what reason we knew not. March 16.—The Bashaw sent word that I should have any thing I wanted, free of expense. March 17.—Ordered not to send our clothes out to wash. March 2/t. — I was taken out of prison to visit a mameluke's wife and child. The minister of foreign affairs paid us a visit", and said many clever things. March 26.—A truce was held between Commodore Preble and the Bashaw. From March the 28th to the 13th of April, I was violently afflicted with the dysentery, during which time the Bashaw expressed much anxiety, and offered me every assistance. April 1").—We felt the Syroc wind, which was very oppressive. April 2.1!.—John Morrison died, in consequence of a hurt he received a few days before while at work under the directions of his new masters. The Ba shaw permitted me, with two of my fellow officers, to go to his garden, con ducted by a guard of two Turks, armed with pistols and sabres. This precau tion, they pretended, was taken to prevent the wandering Arabs and Moors from robbing us ; but it was probably done to prevent our escaping to the squadron, then cruising off the harbour, in sight. May 11.—Our squadron appeared off the town. The Turks were at their quarters. They had twelve gun boats, armed, manned, and moored out in the harbour. May 16. —Ten of our officers took a walk to the gardens under escort of a guard. They returned with a variety of flowers and ripe apricots. May 20.—A party of us, under escort of four Turks, walked to the desert, about four miles from our prison. We ascended a large bank of sand, where we had an extensive view of the country. The deserts have a singular and grand appearance. They extend to Mount Atlas, which we could see at the distance of two day's journey. The sand is in heaps, like snow drifts in our country. There was not a house nor any other object to be seen; nor a thing growing to interrupt the sight ; but it appeared like an ocean of sand. On our return we visited several gardens, where we got oranges, lemons, apricots, and a variety of flowers. We were treated with sap of the date tree, which tasted much like mead. May 20.—A party of us, under escort as before, took a walk into the desert. On our return we dined in the Bashaw's garden, under the shade of orange trees. The dinner was prepared in the Turkish style and we ate with wooden spoons—it was simple and good. We visited several gardens, and were treated with as much respect as could be expected or desired from a foe, who held us as prisoners of war. On returning to town we saw two of our brigs at anchor off the harbour, seeming to defy all the force of Tripoli. June -}. —We are plentifully supplied with squashes and cucumbers. The Bashaw's eldest wife, called the queen, was delivered of her ninth child on the 18th of June. She was twenty three years of age. The first child was born when she was in her eleventh year. It is said to be common to marry at ten. June 27.—Mr. Hodge, our boatswain, Mr. Douglass, the sail-maker, and Mr. Fontaine, the first master's mate, were taken from the prison and set to work by order of the Bashaw. July 15.—The Bashaw, his wives and guards removed to their country seat at his garden. The season was very warm and our close confinement continued. We purchased figs, watermelons, muskmelons and cucumbers. No.I. JONATHAN COWDEBY, SURGEON IN V. S. NAVY. 251 July 28.—I was called to visit the Bashaw's eldest son, the Bey of Tripoli (termed the Prince of Wales of Tripoli, by the English Consul) at his palace, about three miles from town. I found him in a lofty and airy apartment, lying on a mattrass and surrounded by his attendants. I prescribed for him and was highly entertained in the Turkish style. July 29. —The Bey was well enough to return to Tripoli. He called at the door of our prison, which was unlocked and the bolts and bars unloosed. I was conducted to him when he expressed great satisfaction at having recovered his health, thanked me for my attention, and promised to alleviate our misfortunes, as far as was in his power. I was then sent back to prison. The Bashaw and Bey spend a day alternately in town, on account of the expected attack by the Americans. July 31.—I was carried with, my trunk, and bed, to the castle, where a room was provided for me, and the Bashaw informed me I must attend the Ameri cans and his family as a physician. August S.— The American squadron, under the command of Commodore Preble, consisting of one frigate (the Constitution), two brigs, three schooners, and seven gunboats, at about 2 o'clock, P. M. commenced an attack on the bat teries and gunboats of Tripoli. I stood on the top of the castle, where I had a fair view of the engagement. Three of the enemy's gunboats were captured by the Americans. Two Turks swam to the shore, and were carried before the Bashaw, who gave them a suit of clothes and a few dollurs. They said that many were killed on both sides. Aug. 5.—The American squadron nnchored off Tripoli, I was ordered to dress a wound of a mameluke, who had his hand shattered by the bursting of a blun derbuss. I amputated all his fingers but one, with a dull knife, and dressed them in a bungling rannner, in hopes of losing my credit as a surgeon in this part of the country, for I expected to have my hands full of wounded Turks in conse quence of the exploits of my brave countryman. Aug. 9. —At about 12 o'clock the alarm gun of Tripoli was fired. The Trl- politans all took their stations, and went through the Mahometan prayer, by kneeling and kissing the ground several times, with their faces toward the east, all with as much regularity as the exercise in a well-disciplined army. Their military manoeuvring was a scene of the utmost confusion. I got permission to go on the top of the castle, where I had a most extensive view of the sea and land, and saw the American squadron approaching the town. At about 1 o'clock the attack commenced, and the battle soon became vigorous, with a tremendous cannonading on both sides. I now beheld the melancholy catas trophe of the explosion of one of our gunboats. I saw the mangled bodies of my countrymen precipitated into the air. For a few moments a general silence took place, when the firing recommenced with unabated vigor. I saw shells explode, and set fire to the town in many places ; but the houses being prin cipally built of stone, mud and mortar, the fire did but little damage. The shells and shot, however, battered the town very much, and almost destroyed »me of the houses. The firing ceased at 4, P. M. when the ship John Adams joined the squadron. The Bashaw has a bomb-proof room in his castle, where he staid during the action. On hearing of the explosion of our gunboat, he ventured out to take a peep, with the precaution of having a ilarubetct or priest, to seal a black piece of paper on the top of his head, with a Turkish or Mahometan scrawl, with assurances that it would entirely secure him from all danger; but he soon returned to his cell. The Turks all wear a paper of this kind, sewed up In a little velvet bag, with assurances from the itarabeu t that it will protect them in the greatest danger. The Marabewt 108165—22 5 252 JONATHAN CO WDERY, SURGEON IN U. S. NAVY. Vol. XVII. gets a sum of money for these blessings. If a Turk gets wounded or killed, it Is supposed the blessed paper was too old, or not placed in a proper manner. In the time of action the Marabeivt gets upon some secure place and cries to Mahomet in the most dismal yells to let them conquer their enemies; and beckons to the vessels to run on shore or be destroyed. Such of our crew as were able, were put to work, and drove about like horses or mules. Aug. 10.—Lewis Heximer, who lately turned Turk, went by order of th« Bashaw, and told Capt. Bainbridge, the particulars of the two late actions. The Bashaw informed me that the late commander of the schooner Vixen, Lieut. Smith, was commodore of the gunboats in the late action, and was killed by a musket shot through his head. Our men complained of being drove and beat about at an unmerciful rate, In consequence of which they petitioned the Bashaw, in the following terms: " To his Excellency the Grand Bashaw of Tripoli: The petition of the whole of the American prisoners, most humbly sheweth :— " That your humble petitioners, when doing their duty with all their power, as they are commanded, are most cruelly beaten by our wardens, stoned, In sulted, and spit upon by the soldiers and others; required to carry burthens impossible for us to sustain, and chased and bruised, until we are, or soon shall be, unable to labour at all. " From the many acts of justice, kindness, and generosity we have experi enced from your Excellency, we cannot suppose that such conduct is authorized by your commands ; or that we should be punished for what is out of our power to perform ; or for the actions of others, which we have no agency in, and which we cannot prevent. " Returning your Excellency our sincere and humble thanks for your bounty and privileges heretofore shewn, and relying upon your goodness for protec tion, we therefore most humbly pray, that your Excellency would interpose your royal authority and grant us a speedy relief. And your petitioners, as in duty bound, will remain your Excellency's most humble, faithful and obedient servants." On the petition being explained to the Bashaw by Heximer, (or Hatnet Anverikan, his new name) the Bashaw forbid the Turks striking the prisoners. Aug. 11.—The Bashaw sent for me, and, agreeably to his orders,. I took a seat by his side. He began conversation about my country, and our squadron, which was then in sight, and consisted of eighteen sail- He said that for two dollars he could repair all the damages that the bombardment did to his town; that but one man was hurt by the shells ; that what he had been effered for the American prisoners was but fifty dollars per man ; that he would make them earn that sum in two months. He asked me what I thought my country would give for me. I told him I did not know. He said he would not take twenty thousand dollars for me; to which I replied, that I might then expect to re main in slavery for life. He patted me on the shoulder and said, I might then content myself to stay with him. I asked to go and see our men, but he refused, saying, that Moors and Arabs would kill me if they could catch me. Aug. 12.—Our squadron hoisted a flag of truce, sent in a brig and schooner and tired a gun. The Bashaw did not, and swore he would not, answer it; and said lie would not treat witli commodore Preble. A truce however was after wards held. Consul O'Brien wished to come on shore, but was refused. Aug. 13.—Another truce was held, when the Bashaw demanded one million of dollars for our ransom. One hundred and twenty thousand dollars were offered and refused. Aug. 17.—The Bashaw informed me that fifteen Americans were found drifted ashore at the westward of the town, and that one of them was an No. 2. 253 JONATHAN COWDERY, SURGEON IN U. S. NAVY. officer with an epaulet on the right shoulder. We supposed they were men destroyed by the explosion of the gunboat, in the lute engagement. I asked permission to go with two or three of our men and bury them, and the Bashaw told me I might go the next day. Our squadron lay at anchor off the harbour. The inhabitants had chiefly moved out of the town, through fear of another bombardment ; and the Bashaw ate, drank and slept in his bomb proof room. Several tribes of the back country inhabitants had lately come and offered their services to the Bashaw, —in all not more than one thousand men. Many of them had muskets without locks, but had a sort of match to put fire to them. They were almost naked, half starved, and without discipline. When (hey are going to battle or appear before the Bashaw, they run to and fro, shaking their rusty muskets over their heads, all crying Holouet Buoy (I am my futher's son.) Every tribe has a priest, or what they call Marabeict, whose badge is a small green flag, which is carried in his hand or stuck up at his tent. They pretend great skill in prophecy, in which the people put the utmost faith. They prophecy success in battle ; and for a small sum of money, ensure any one against wounds or death in fighting a Christian. They often go on eminences, and beckon and sing to the American vessels to run on shore. They prophecied that another American vessel was to go on the rocks, and the Bashaw fully believed it. Aug. IS.— Was not permitted to bury our dead. Our squadron stood out to Bea. At evening the Bashaw went to his country seat and the Bey came in to keep the throne till his father's return. They never both leave the castle at once. When the Bashaw leaves it, the gates are shut till his return, for fear of incursions upon the throne. In the evening, th« moon shining very brightly, the prince or Bey ordered out the band of music, which was very ordinary, and made Christians, Turks, Arabs and Guinea Negroes dance be fore him, according to the mode of their respective countries, at which he seemed highly diverted. Aug. 19.—Between 0 and 10 o'clock in the evening, Mr. Church, a respectable English gentleman was shot through the head in the street, on his return from visiting bis neighbours. Aug. 2k-—In the morning, between 2 o'clock and daylight, two of our small vessels- hove about thirty shells, as was supposed for the round fort, but they all fell short of the mark. Such attempts served rather to encourage than to intimidate the Tripolitans ; and the Bashaw was in high spirits on the occasion. Aug. 26.—At about 4 o'clock P. M. the fellow who murdered Mr. Church, was executed near the spot where the crime was committed. It had theretofore been a custom in this country, when a person had committed murder, to fly to a tomb of a Marabewt (or priest) where they were protected from justice, and a fee to a Marabeict would procure them absolution. This fellow fled to a place of this kind immediately after killing Mr. Church. The English consul, Mr. Langford. on being informed of the murder, addressed the Bashaw, and de manded justice. The Bashaw then found out by a boy, who accompanied the murderer when he committed the crime, the particulars of the affair ; and im mediately sent a file of men and ordered them to prevent any person carrying food or drink to the murderer. They watched him until night when the Bashaw sent his Marabewt, who coaxed him away, brought him to the castle and con fined him in irons. The next day the Bashaw called his divan, when it was de cided that the prisoner was guilty of wilful murder, and ought to suffer death. It appeared by the evidence and confession of the prisoner, that Mr. Church had lent a sum of money to a Spanish carpenter in this place:-— that Mr. Church had pressed him for payment ; and that the carpenter's wife hired the Turk to kill Mr. Church for forty dollars. The villain took his watch from his pocket 254 JONATHAN COWDERY, SUKGEON IN U. S. NAVY. Vol. XVII. after he had shot him. The boy who accompanied him and carried a lantern was bastinadoed with five hundred blows. The carpenter's wife was ordered to leave Tripoli. Aug. 27.—Our squadron stood towards the harbour. Aug. 28.—About 4 o'clock in the morning, I was awoke by a heavy and inces sant fire of cannon, and the whistling and rattling of shot nil around me. On getting up, I found that our gun-boats were close in, and were firing upon the town and batteries. Every gun in Tripoli that could be brought to bear, was returning the fire. The Tripolitan gun boats were close under the castle for protection. The firing continued until a few minutes after sun-rise, when one of the largest gun boats ventured out, with an Intention of boarding the nearest American boat. As soon as she got within pistol shot, the American discharged their piece, loaded with grape, and killed four and wounded two of the enemy, they then put about and retreated. At the same time, commodore Preble bore down and gave the batteries to the westward of the town two broadsides. The squadron then stood out and anchored off the harbour. The damage done to the town was considerable. A large vessel was sunk in the harbour and others damaged. Many men were killed and wounded. Aug. 29.—The Bashaw sent me to his palace in the country, to see his eldest son the Bey, whom I bled in the foot. He requested me to spend the day and dine with him, which I did. He endeavoured to have the dinner in the Christian style. It was set on a table, and consisted of a large dish of boiled rice and stewed fowls, out of which we both ate, he with a wooden spoon, and I with a silver one, without knife or fork. The prince's servant stood by him, and pulled the fowl in small pieces with his fingers, for the prince to eat. I -made use of my fingers and teeth to get mine in pieces. Our dessert was dates and water melons. Our drink was lngby, or the juice of the date tree, which we drank out of a large gold cup. He shewed me the garden, and took great pains to entertain me. Aug. SO. —A truce was held, I took a ride upon a mule about eight miles to the westward of the town, in company with my guide, Hamet, a Turkish officer, and several footmen. I there saw a boat, which drifted on shore, with a dead man, and several muskets and swords in it. The man appeared to have been shot through the body with a cannon ball, which hnd also pierced the bottom of the boat. The Turkish officer collected about twenty Arabs, who hauled the boat upon the beach, dragged the dead man out of it, stripped him entirely naked, and left him on the beach. I tried in vain to hire the Arabs to bury the body ; they said it was contrary to their religion to bury a Christian. I asked permission to get him buried by our countrymen, some of my fellow prisoners, but was refused. I found that our men, who were destroyed by the explosion of the gun-boat, on the 9th inst. lay in a state of putrefaction on the beach. They were scattered on the shore for miles, and were torn in pieces by dogs. The Bashaw had frequently promised me that these men should be buried ; but refused to let me take some of our men to go and bury them. September ?.. — At about 4 P. M. our squadron commenced another attack on the town in which eight of our gun boats drove sixteen Tripolitan gun boats under the battery on the east side of the harbour; while the Commodore bore down and gave the batteries at the west end of the town, several broadsides. Many of his shot came into the town, and castle. Two bomb-ketches were employed In heaving shells into the town, which did considerable damage to several houses, and entirely destroyed the house of the Spanish carpenter, the Bashaw's naval constructor. I observed the utmost confusion and random- firing among the Tripolitnns. It appeared they were almost out of powder. Two of their guns bursted, one of which was an eighteen pounder from the No. 2. JONATHAN COWDERY, SURGEON IN V. S. NAVY. 255 late Philadelphia frigate. The men, women and children ran out of the town in the utmost terror and distraction. .Sep*. 3.—Had been to see the prince in the country, and was returning about 10 o'clock in the evening, with the Bashaw and suit, when we saw a most extraordinary light or flash, and heard a heavy report. We all wheeled about, and made for the place we had left ; but the Bashaw soon altered his mind, and proceeded to town, while I went to the country palace and staid all night The explosion was a fire ship sent Into the harbour by Commodore Preble, which did but little damage. Sept. 5.—The Turks found ten dead men near the place where the vessel blew up, on the evening of the 3d instant. The Bashaw and his people had a thanksgiving to Mahomet on the occasion. Their ceremony was prayer in doleful tone, and singing, accompanied with the sound of an instrument made by drawing a skin over a hoop. Sept. 6.—More men were found, three of which appeared to be officers. By permission, I took our boatswain and a gang of men, and buried these bodies a little east of the wall of the town. All that I saw, who appeared to have been killed by the explosion, amounted to fourteen. The Bashaw's son-in-law told me that six more had been found drifted on the western shore ; but I could not ascertain the truth of it. Sept. 7.—John McDonah died of a consumption, with which he had Ion? been ill. Sept. 9.—The Bashaw took me with him, and his suit to his country seat where we spent the most of the day. About 5 o'clock P. M. we went to see the great Marabetct, or Mahometan priest, In whom the Bashaw had great faith, and thought he could foretell events. It was said by the Turks, that he fore told the stranding and capture of the Philadelphia ; that he got offended with the Bashaw and caused and foretold her being burnt. But I had beard nothing of these mysteries until a little previous to this. He now said that the com modore's ship, the Constitution, would never return to America ; that she would either be blown up, or run on shore ; and that the Bashaw would have success in his warfare with America. It appeared that this great prophet was a sojourner; and that he only came to Tripoli when the Bashaw was in want of a prophet. He was encamped on the sandy desert, at a tomb of an ancient Marabewt. The tomb had a house over it, with several rooms, and was en circled with several green trees. It was about two miles back of the gardens. We found this great Marabewt standing on a large mat, which was spread on the sand under the shade of a large mulberry tree. About thirty of his attendants stood back of him. paraded in form of a crescent. I was ordered to pull oft my hat; and all approached him from the west; the Bashaw, with «ome of his most truly attendants in front. When we came near to him we all dismounted. The Bashaw run to him, kneeled before him, and kissed his hand. The mamelukes followed his example. The Marabewt then sat down, and was followed by the Bashaw and his suit, forming a circle on the mat. During this time, I stood by my mule, about five rods from the scene, with my hat in hand. I was soon called and ordered by the Bashaw to take off my slides and feel the Marabewt's pulse. I left my shoes at the edge of the mat, or holy ground, and stepped on. I laid my hat on the edge of the mat in Preference to laying it on the sand ; but it was immediately taken off. I was then ordered to approach his holiness and kiss his hand. I felt his pulse; but before I had time to prescribe for him, he put his hand against me, and gave me to understand that I must go off the holy ground. Immediately stepped off; put on my shoes, took my hat, and went to my mule. The Bashaw called me back, and asked what I would do for the Marabewt. I recommended 256 JONATHAN COWDERY, SURGEON IN V. S. NAVY. Vol. XVII. bleeding: but the Marabewt, shook his head and gave me to understand that lie wanted nothing of the kelp (the Dog). I whs then told to withdraw, which I did, and took a walk round the tomb, which I found to be very ancient. The Bashaw spent about half an hour with the Marabewt, when he kissed his hand ; and we all returned to the country. The Bashaw apologised for the impoliteness of the Marabewt, and said that they had a foolish antipathy to all but Mohometans. October —None of our cruisers were to be seen from the top of the castle. The Tripolitau gun boats were disarmed, and the Bashaw's gunners were em ployed in drawing the charges from the cannon on the battery. Many of the guns now stood in the sand, as they did when Commodore Preble first attacked the town. On being fired two or three times, they recoiled into the sand so deep that they could not be worked, and were abandoned. The Bashaw told me that if he had three frigates, he would blockade America. He said he could do it as easily as a frigate and schooner could blockade Tripoli ! Oct. 26. —A great scarcity of grain. Our crew had no bread for three days. The Bashaw gave orders to all the market people, not to sell grain to anybody but his household. There was no bread to be had for money. A dispute took place between the Bashaw and the renegado Lysle, about the purchasing of some barley. Lysle was considerably intoxicated, and insisted on his right to purchase grain in the market. The Bashaw was highly affronted, and flew at him with all his might, struck him, and ordered his mamelukes to disarm him and put him in prison, which they strove to obey, and carried him off. The Bashaw, however, soon ordered him released, and then ordered his servant, who was supposed to be the cause of the quarrel, bastinadoed with five hun dred blows, which was Immediately put into execution. November 9. —The Bashaw had an epileptic fit, and his people thought he was possessed with the devil. They performed many ceremonies to cast him out, which they said succeeded. The Turks said they saw many ghosts the night before; and that a Marabewt drove the devil out of the Bashaw. December 6.— Our men suffer for the want of provisions. The Bashaw does not allow them either victuals or cash.—They get but a small allowance of bread, and that on the credit of their own country. They are beat unmerci fully and compelled to work hard every day. Dec. 7. —I was informed, that, through the Influence of many Turks, the Bashaw had given orders to Sarcey, our master, to treat the American prisoners with the utmost cruelty, In' order to induce the United States the sooner to make peace. He was impatient for his money. Dec. 10. —Our men all agreed not to work unless they were fed, and accord ingly when the wardens went to the prison and ordered them out, they all refused. The wardens whipped them until they were tired, and then went to Inform the Bashaw, who immediately ordered them bread and oil, and they went to work. Dec. 21.—At evening, the Bey. the eldest son of the Bashaw, was married to his first cousin, eldest daughter of the Bashaw who was driven out of Tripoli by the present Bashaw. The bride was said to be very handsome, and but twelve years old. Our boatswain, carpenter, sail-maker, and first master's mate, who had the liberty of the town for a few months, were put in close confinement with our other officers, on suspicion of attempting to raise the crew to take the town. Dec. 25. —The Bashaw's son-in-law, Selira, who had charge of the stores, was detected In selling a quantity of cordage to a Tunisian merchant. The Bashaw ordered him five hundred bastinadoes, but Selim fled to a Marabeict for protection, and escaped punishment. No. 2. JONATHAN COWDERY, SURGEON IN U. S. NAVY. 257 January 24.—Renegade Wilson, who pretended to be a great engineer, was ordered by the Bashaw to fire hot shot at a mark, but succeeded indifferently. The Bashaw, however, was highly pleased, gave Wilson eight dollars, and promised to reward hira in proportion to his exertions in his future warfare. Wilson engaged to teach the Turks how to throw bombs, hot shot, and hand grenades ; and to alter and improve the fortifications, etc. Jan. 25.—The Bashaw sent me to visit the wife of Alia Mameluke. She was once a wife or concubine to the Bashaw, who gave her as a wife to his favourite. She was sister to a wife of the Emperor of Morocco, about eighteen and very handsome. She was in child-bed travail, attended by a number of Jewish women. She was delivered of a son, her first child, to the great joy of all the Turks in the castle, male and female. It was proclaimed by a loud yelling, with clapping of hands to and from the mouth, by the women of the castle. Jan. 28.—The Bashaw was informed by Wilson, the renegade, that our crew were all armed, and about to rise upon the town. Search was made, and the report found to be false. But the Bashaw was much intimidated and an addi tional guard was placed over us. February J.—George Griffiths, one of our crew, having informed the Bashaw that he could build an air furnace, and cast guns, shot, etc., was furnished with a mason and nine of our crew, and set to work, with a promise he should have a hundred dollars for the first shot he should cast. After expending about five hundred dollars in the experiment, Griffiths this day attempted a blast in his furnace ; but with all the wood and coal that the Bashaw could furnish, he could not melt the iron, and the furnace cracked in several places. It afterwards appeared that Griffiths had no intention to cast any shot. Feb. 5.—While a number of our men were at work at the north corner of the castle, a large body of the wall fell, and killed Jacob Dowdesher. The only consolation we received from the Turks, was, that he was amak deric and sansafedah —that is D n his mother, he has got no faith, Romo Kelfi —He it a Christian dog. March 1.—An American frigate appeared off the harbour. The Turks were all at their quarters, and were manning their gun boats. The Bashaw was preparing an armament to go against some of his refractory tribes on the borders of Egypt. March 4-—Hassan Bey, the Bashaw's chief raameluke, was appointed to command the expedition towards Egypt, on the borders of the dominions of Tripoli. Hassan and his officers were attended by the Bashaw and several stand of colours to a ilarabewt about three miles from town to receive abso lution and assurances of victory in the intended expedition. A great part of our crew, and many Turks and Jews were employed In packing up ammunition, etc., for the camp. March 5.—Two frigates and a brig, supposed to be American, appeared oft the harbour. The people of Tripoli were preparing and moving their effects Into the country, expecting a siege by the Americans. March 12.— Swallows appeared. Apple, peach and plumb trees were in blos som, and peas in market. March 17. —Walking by the house called the American house, I perceived that It was full of Turks, and a strong guard was at the door. On inquiry, I found that they were the sons and nearest relations of the Bashaw's officers, who had gone in the expedition to the frontiers. The Bashaw kept these people as hostages for the fidelity of his officers, whom it appears, he was afraid to inist, least they might join in the rebellion and come against Tripoli. It was 258 JONATHAN COWDEEY, SURGEON IN U. B. NAVY. Vol. XVII. said that his highness had received a letter, stating that the Americans were making great preparations to attack Tripoli. A tent was pitched on the bat tery of the castle, and orders given to keep watch all night, and every night afterwards. Orders were also given to make every preparation to repel the Americans. March 18.—The Bashaw sent his son-in-law into the country for troops to protect Tripoli. March 19.—It was reported and generally believed that the Americans had been to Alexandria' in Egypt, where they had got the Ex-Bashaw * and four thousand Egyptians, and carried them to Syracuse* where they were to be landed to act in concert with the Americans against Tripoli. I perceived many private councils and long faces amongst the Turks. March 21.—A frigate and brig appeared off the harbour. The Bashaw told me he suspected commodore Barron was dead, as he had not heard from him for a long time. Not long before, he told me, that he had heard of the death of his brother the Ex-Bashaw. He seemed highly pleased at such news. Sev eral of the sons and dearest friends of his chiefs In the country, were brought into the castle, as hostages for their fidelity to the present Bashaw. Symptoms of dissatisfaction appeared amongst the people. March 22.—Two negroes were hung at the gate of the city for robbery. The Bashaw's son-in-law who had been sent into the country to collect troops to protect Tripoli, returned without success. The people refused to fight for the Bashaw, because he had made unusual demands for money, and even had stripped their wives of their jewels. For several days it had been reported that ten thousand troops were to muster on the beach near the town ; and his highness was to make a speech to encourage them to fight for him against the Americans and his brother. I prepared myself to see these troops; but to my disappointment not one of them appeared. April 7.—One of our cruisers appeared. A large gunboat was launched, which was built by the redegade West, who was one of our crew, and turned Turk. April IS.—The Bashaw received an unfavourable letter from his agent at Malta, concerning the armament of the Americans. The Spanish consul pre sented the Bashaw three hundred stand of arms and a number of pistols, and, it is said, advised him to keep up the war, and force the Americans to pay his demand. It was concluded that the Bashaw's women and children should stay at the castle during the summer. They said that if they must be taken, they would rather fall into the hands of the Americans than the Arabs. April IS.—The Bashaw declared, that If the Americans drove him to extremities, or attacked his town, he would put every American prisoner to death. April 19.—The Bashaw interrogated me concerning the force of my country ; -he asked me how many marines the United States kept In pay. My answer, for good reasons, was, ten thousand ! How many troops? he asked.—Eighty thousand, said I, are in readiness to march to defend the country, at any moment; and one million of militia are also ready to fight for the liberty and rights of their countrymen ! At this, his highness assumed a very serious look, and I returned to my room. • It has been mentioned that the ex-Bashaw, Hamet Caramelll, after falling to gain any advantages in his brother's forces, had withdrawn from Derne early in 1804, and gone to Egypt ■At this time the United States utilized the harbor of Syracuse as a base from which to operate against Tripoli. A naval hospital had also been established at Syracuse. No. 2. 259 JONATHAN COWDERY, SUBGEOK IN U. S. NAVY. April 27.—A very oppressive Syroc wind. Several companies of Arabs hail arrived within a few days : about three hundred horse and seven hundred foot. ' May 3.— The Bashaw and suit went very early this morning to the great Marabeict, of whom some particulars have been before mentioned. He was to continue with the Bashaw during the contention with the Americans. He now nssured the Bashaw that the American frigates would be destroyed ; and that the gunpowder of the whole squadron would be so damaged, that the Ameri cans would not be able to fire a gun. He agreed to attend the Bashaw, to keep the balls and shells from hurting him. He receives large sums of money from the Bashaw. May 1-J.—I received a note from capt. Bainbridge, stating the inconvenience which the officers laboured under by being in close confinement and by breath ing unwholesome air. I spoke to the Bushaw on the subject, and humbly solicited that our officers might be removed to the American house. The Bashaw replied, that the war between him and my country at first was about money; but now it was whether him or his brother should be the Bashaw; and that the Americans had bound themselves to his brother In such a manner that it was not in their power to make peace with him. But that his brother and the Americans were determined to take Tripoli and take off his head. He swore by the prophet of Mecca, that If the Americans brought his brother against him, he would burn to death all the American prisoners except me; that my life should be spared, because I saved the life of his child when very sick. He went off In a great passion, and mounted his horse. His mamelukes and guard, to the number of about forty, attended him, and they took a ride to his country palace. They returned about sun set, and the minister of exteriour relations and the Bashaw were in private conference. May 19.—A spy employed by the Bashaw, arrived from Malta and Syracuse. He brought news that the American squadron sailed for Alexandria in Egypt about twenty days before; that it consisted of 4 frigates, 3 brigs, 3 schrs. 24 gun boats, 6 bomb ketches, and several transports ; that they were to take on board the former, or Ex-Bashaw, and to proceed along the coast of Tripoli, and take the principal towns; and then to attack and take the town of Tripoli, and put it in possession of the Ex-Bashaw. The Bashaw and his people seemed much agitated at this news.' 'General William Baton waa born in Woodstock, Conn., on the 23d of February, 1764. Ar a boy he served for a short time in the Continental Army. He graduated from Dart- month College in 1790, wag cleric of the lower house of the Vermont legislature in 1791-92, and then reentered the Army as a captain, later serving against the Indians in Ohio and Georgia. In 1797 be was appointed consul to Tunis, where he arrived in February, 1799. While In Tunis he became acquainted with Ha met Caramalli, the rightful pasha of Tripoli, who about the year 1792 had been deposed by hlB brother Tusuf. When, In 1803, because he refused to comply with the extortionate demands of the bey of Tunis, Eaton was driven from tbat country, he returned to tie United States to urge American intervention for the restoration of Hamet Caramalli to the throne of Tripoli on condi tion of a permanent peace and no tribute, arguing that this would impress the Barbary States with the power of the United States. On reaching Washington he succeeded in exciting a moderate amount of interest In his project to cooperate with Hamet Cara malli, who in the meanwhile had taken up arms against his brother Yusuf, bad been defeated, and had early in 1804 withdrawn to Egypt. In May, 1804, Eaton was appointed Navy agent and placed under the orders of Com modore Barron. To the latter the Secretary of the Navy wrote, June 6, 1804 : " With respect to the ex-pasha of Tripoli, we have no objections to your availing yourself of his cooperation with you against Trjpoli. • * * In such an event you will, It Is believed, find Mr. Eaton extremely useful to you." Commodore Barron's squadron sailed for the Mediterranean in June, 1804, arriving at Malta in September, and the .following month Eaton was sent in the Argus to Egypt 260 JONATHAN COWDERY. SURGEON IN TJ. S. NAVY. Vol. XVII. May 21. —The Bashaw with his attendants rode into the counry. According " to custom he took with him on a mule, two hoxes. said to contain twenty thousand sequins, (forty thousand dollars). But I did not believe they con tained that sum. They were light. I had lifted them both ; and they were carried to and from the mule by one slave. Another mule was loaded with the At Cairo he lenrned that Unmet, with a fow of his followers, had Joined the Mamelukes, who were at war with the Ottoman Government, and was at that time besieged at Mlnieh, 150 miles or more up the Nile from Cairo. The prospect of getting into com munication with him seemed doubtful. En ton obtained nn audience with the Viceroy of Egypt nnd frankly explained the object of his visit. The Viceroy, delighted at an oppor tunity of ridding his country of an enemy, promised an amesty for Hamet and his followers and a passport through the Turkish lines. In the course of time Hamet and his followers nppenred at an appointed rendezvous. Eaton's plnn had been to embark with Hnmet on the Argus and to proceed from Alex andria to a point near Derne In Tripoli where they would meet Hamet's troops and cap ture the city, but it was thought best to go by land, chiefly because it was feared that Hamet's army would evaporate In his absence. He therefore formed his camp some distnnee to the west of Alexnndrin. Arrangements were made for the Argus to meet the expedition at the Bay of Bomba with supplies and reinforcements. Eaton entered into a convention with Hamet in which it was provided that the Gov ernment of the United States should reestablish him In the possession of his sovereignty of Tripoli and that' the expense Incurred by the United States was to be repaid by Hamet out of the tribute derived from certain other nations. Eaton's little nrmy was composed of about a dozen Americnns from the Argus, including Lieutenant O'Bnnnon of the marines and Midshipman Peck ; 25 cannoniers of various nationalities, with 3 officers ; 38 Greeks, with 2 officers ; Hamet nnd his suite of 90 men ; a party of Arabian Cavalry under Sheik el Tahib and another chief ; a number of footmen and camel drivers, altogether about 400 men, and a caravan of 107 camels and a tew asses. This expedition to Derne is of Interest because It was the first American force to operate on foreign soli. The story of the expedition Is splendidly told in Gardner W. Allen's " Our Navy and the Barbary Corsairs," from which the following Is quoted : " On March 8, 1805, the march was begun across the Lyblan Desert to Derne, a distance of between five and six hundred miles. For the greater part of the way the route lay within Right of the sea. Wnter was generally obtained from natural basins worn In the rocks by the streams during the wet season, and filled with rain water ; but there was often great scarcity of water and suffering for want of it. An advance of 15 miles was made the first day, and then on the following morning the owners and drivers of the camels became mutinous and demanded advance pay. In this they were encouraged by Sheik el Tahib, one of the Arab chiefs, who made trouble during the whole march. This difficulty caused a delay of a day and a half. Hamet was lrresolate and seemed to have no Influence with the Arabs. At last Eaton, finding argument fruitless, assembled the Christians ' and feinted a countermarch, threatening to abandon the expedition.* This had the effect of checking the mutiny, and the march was resumed. On the 13th a courier from Derne appeared and announced to Hamet that the Province was preparing to support him. This news caused rejoicing and a discharge of firearms, which alarmed the Arabs in the renr. who thought nn attack was being made. They thereupon at tempted to disarm and massacre the Christians escorting the caravan, but were restrained by one of their more prudent chiefs. " March lfi and 17. there was a cold rainstorm, and the Arabs again became mutinous. On the 18th, having advanced about 150 miles, Eaton learned that the caravan had been freighted by namet for this distance only. The owner.8 finally promised to proceed two days farther, upon being paid. This took nearly all the money Eaton had, and when they had received it, all deserted, part the first night and part the second, setting out on their return to Egypt. Sheik el Tahib nnd other chiefs now refused to proceed until news should be brought from Bomba that the United States vessels were there, and proposed to send a runner to ascertain the fact. Eaton ordered their rations stopped. These com plications consumed three days. The Arabs finally yielded, about hnlf the caravan was induced to return, and the march was resumed. " March 22, they arrived at a great plain, bordering upon the sea, inhabited by thousands of wild Arabs who had never before seen Christians or tasted bread. They had vast herds of camels, horses, nnd cattle, and countless sheep and goats. Hamet was here reinforced by 80 mounted wnrrlora, and a caravan of 90 camels was freighted: and later another force of Arabs, including 150 warriors, with their families, Joined the expedition. Xo. 2. 261 JONATHAN COWDERY, SURGEON IN U. S. NAVY. packages of the Bashaw's clothing. The Bashaw always wont thus provided, through (far that he might be served as he served his brother the Ex-Bashaw, who was denied to return to the castle when the present Bashaw usurped the throne. During the absence of the Bashaw, his eldest son, the Bey, had his amusement. He ordered two carpets spread on the south corner of the cnstle. On the 2flth a courier announced that a large force, sent by Yusuf Pasha, was marching from Tripoli to Dome. This canned another panic, Hamet hesitated and wavered, the camel drivers fled with the caravan, and Sheik el Tahlb deserted with pnrt of his tribe and a large number of other Arabs. Hamet begged Eaton to offer inducements for the Sheik to return. This Eaton refused to do and was glad to be rid of him, but he soon came back of his own accord. On the 28th Hamet's slender stock of resolution seemed to have oo»ed away completely, and he decided to abandon the enterprise and return to Egypt. Eaton kept or. with the baggage, and in two hours Hamet followed him. That evening all the Arabs that had Joined a few days before deserted, having been discouraged by Shiek el Tahl!>. An officer was sent back after them and returned with them the following afternoon. "The next complication was a quarrel between Sheik el Tahlb and another Sheik, which ended in the lntter's deserting with many others whom it was Important to retain on account of their influence with Arabs near Derne. Hamet went back to induce them, If possible, to return. ' From Alexandria to this place.' wrote Eaton, ' we have experi- inced continual altercations, contentions and delays among the Arabs.

This experiment showed that fans up to a certain limit will give great relief; this limit being approximately the body temperature (98.5° F.) and very high relative humidity. The effects of convec tion and evaporation from a fan would then cease to operate. 7. When the above limits had been approximated in the experi ments, cold water was run through coils, thus giving a cooling unit as well as a surface for precipitation of moisture. The fan was left on and rapidly passed the moist, hot air over the cold coils. 8. complete relief was obtained in this way. 344 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE.

HEALTH CONDITIONS OF THE NAVY. Health conditions of the Navy are better than they have been at any time during the past five years. The annual admission rate for all causes from January 1 to July 8 being 589 per 1,000 per annum, as compared with 776.27 for 1918, 676.02 for 1919, 778.99 for 1920, and 625.65 for 1921. The morbidity rate for all causes for the four- week period ending July 8 was 385 per 1,000 per annum ; for diseases only, 340 per 1,000 per annum; and for injuries and poisons, 45 per 1,000 per annum. With the exception of malaria, there have been very few com municable diseases reported during the past four weeks. The fol lowing table compares the admission rates for certain diseases for June, 1922, with the average admission rates for that month for the previous four years. Annual admission rates per 1,000 for certain communicable diseases, current month of June, 1922, in comparison icith the mean annual admission rates, month of June, for the four-year period 1918-1911, inclusive.

DIVISION OF PREVENTIVE MEDICINE. It will be noted that the morbidity rates for measles and mumps are exceptionally low; this is no doubt due to the fact that few recruits have been inducted into the Navy during the ;past few months. Although the admission rate for malaria is lower than the average, it is believed that this rate should be further lowered. Very few admissions for malaria are being reported from stations in the United States, except Quantico, or from ships serving in and around United States ports; the vast majority of the cases were reported from San Domingo and Haiti. The annual admission rate for venereal disease for the four- week period ending July 8 was 96 per 1,000, which is considerably lower than the annual admission rate for 1919, 1920, or 1921. The progressive average rate for venereal disease for 1922 is now 107 per 1,000 per annum. PREVENTIVE MEDICINE EDUCATIONAL MATERIAL. The Bureau of Medicine and Surgery has forwarded to all ships and stations within the past month a set of posters dealing with general, personal, and social hygiene. It is requested that medical officers inform the Bureau of Medicine and Surgery if the material now being supplied to ships and stations is of sufficient value to continue such an educational campaign. If such posters are re ceived favorably by the commanding officers and medical officers of ships and stations, new sets of posters dealing with the pre vention of diseases and accidents will be forwarded to ships and stations from time to time. In order to keep a constant flow of material it will be necessary for medical officers to furnish the Bureau of Medicine and Surgery with sample posters and, if pos sible, with actual photographs of conditions existing at sea or at naval stations. If each medical officer of a ship would forward to the burean one such poster a month or, in fact, even one a year, ample material would always be available to provide a steady flow of posters. Many accidents and diseases occur in the Navy each year which could be prevented. It is not so easy to obtain photographs showing how disease occurred and how it may be prevented, but it is a very simple matter to obtain photographs of the place of the accidents and consequences therefrom. Such photographs when placed upon posters attract attention and lead men to read the lessons contained thereon. The next set of posters to be forwarded to ships were obtained from the National Safety Council. Many of these are excellent, but No. 2. DIVISION OF PREVENTIVE MEDICINE. 355 unfortunately they do not depict the life and environment of the bluejacket. It is considered that it would be far better if the Navy Department could make their own posters instead of having to call on civilian organizations. Such posters, however, will demonstrate to the medical officers the extent to which civilian manufacturing establishments are progressing along these lines. In addition to posters, the Bureau of Medicine and Surgery is hav ing made a series of lantern slides which may be used at the regular motion-picture shows while reels are being changed. Such slides will be self-explanatory and will not require a lecture by the medical officer in conjunction with them. If the medical officers so desire another set of slides will be made for lecture purposes. Here, also, it will be necessary for the medical officers throughout the Navy to furnish the Bureau of Medicine and Surgery with new ideas and necessary material for producing such slides. "Within the next month a 12-reel motion-picture film, entitled " The Science of Life," will be forwarded to the commander in chief of the Atlantic Fleet, the commander in chief of the Pacific Fleet, and to the naval training stations, Hampton Boads, Va., and San Francisco, Calif. Later, such a film will be forwarded to the com mander in chief of the Asiatic Fleet. Medical officers afloat who desire to show this film may obtain it by forwarding a letter to the commander in chief of their respective fleets. This film has been produced by the Bray Productions (Inc.)*, New York, N. Y., in co operation with the United States Public Health Service, the United States Army, and the United States Navy. The first four or five reels may require some explanation, inasmuch as these reels were produced largely for high-school students, but the remaining reels are self-explanatory. The following subjects are covered in this motion picture : General biology. Protoplasm, the beginning of life. Reproduction in lower forms of life. Interdependence of living things.

ACCIDENTS AND INJURIES AMONG CIVIL EMPLOYEES AT NAVAL ESTAB LISHMENTS DURING 1921. An endeavor has been made to analyze the accidents and injuries occurring among civil employees at naval stations, reported in the annual sanitary reports for the year 1921. As the basic data from several navy yards and stations were obviously incorrect in many in stances and the totals for "location of injury" and "cause of accidents" did not balance, no accurate conclusions can be drawn from such an analysis. However, it is believed the medical officers acting in the capacity of industrial physicians may obtain useful information from the following tables : Table I compares the number and type of injuries occurring at certain navy yards and shore stations : Reel 11.

It will be noted that the naval station, Mare Island, Calif., had an average of 7,411 civil employees; the navy yard, Philadelphia, Pa., 7,775; and the navy yard, Washington, D. C, 6,388, and that the total number of injuries for the naval station, Mare Island, was 6,062; the navy yard, Philadelphia, 6,134; and the navy yard,. Washington, 3,331. More than likely, the reason the navy yard, Washington, had fewer injuries than either Mare Island or Phila delphia, all of which are comparable as they employed approxi mately the same number of men, was due to the fact that this was the only navy yard or station which employed a safety engineer. Table II shows the frequency of various types of injury, the parts of the body injured, and the cause of the accident as well as the total number of injuries for civil employees, the number of men who lost time, the average number of days absent of cases that lost time, and the average days absent of the total number of cases for various types of injuries.

Vol. XVII. It is fully realized that there are many apparent inaccuracies in Table II, particularly when it is compared with Table I, most of which are due to the fact that the report from the navy yard, Ports mouth, N. H., is included in this table, whereas it was not considered in Table I. There are also a few inaccuracies due to faulty basic data. However, this table does show the injuries most frequently encountered in navy yards and stations, the parts of the body most frequently injured, and the principal causes of accidents among civil employees. Since the instructions relative to the preparation of statistics of accidents and injuries among civil employees did not reach the medi cal officers concerned until the latter part of the year, they could not be expected to have the necessary basic data with which to prepare the form in the annual sanitary report. For the year 1922 every medical officer should have the necessary basic data and tables from stations should be correct. If so, the tables published by the Bureau of Medicine and Surgery next year will be of immense value not only to the medical officers in the field but to various civil industrial concerns. MENTAL HYGIENE AND DELINQUENCY.1 By WiLLiiM Healy, M. D., Judge Baker Foundation. At present mental hygienists are endeavoring to get before legis lators, people in charge of institutions, judges, probation officers, and others who handle delinquents an understanding that an important proportion of delinquency is directly related to abnormal function ing of the mind. But it was not many years ago that the reverse was true ; we can read case histories of 10 years ago and find reformatory heads insisting to psychiatrists that certain individuals were insane, although as the result of some professional examination they had been declared sound mentally. We could give many instances of this, showing a point of view that differs widely from that taken by modern psychiatry. A very striking though short paper appeared in the "British Medical Journal" in 1906, written by a certain Justice Rhodes, who plumped the question at the medical profession concerning whether the crime situation in England was not one for prime consideration by that part of the medical profession which had to do with mental diseases rather than one to be decided merely through legal methods. He very pertinently asked what could be the meaning of the fact, for instance, that of 186,000 convictions in 1906, upward of 10,000 ' Reprinted from The Commonwealth, Massachusetts Department of Public Health, by permission of Eugene B. Kelley, H. D., commissioner of health. No. 2. 361 DIVISION OF PKEVENT1VK MEDICINE. of those convicted had been sentenced more than twenty times before. In all common 6ense, was this more likely to be a matter that could be remedied by continuation of these same legal methods, or was it a matter for the deeper understandings that might come through medico-psychological studies of these individuals? And concerning recidivism itself, the repetition of offense, one may recognize at once that this is one of the cardinal points of the problem of delinquency. The individual who, taken in hand by the law, does not profit by his experience, even by punishment meted out to him, what can be his mental make-up? The figures of recidivism for this country can not be given, because as yet we have developed no sort of general or nation-wide study, not even statistical, of our most expensive problem of delinquency and crime. But if one looks up the facts of any of our metropolitan institu tions for criminals, one finds that they readily approach the figures found in the " Blue Book of Crime and Statistics " in Great Britain, or the carefully worked-up statistics that are available from other countries. The implications of recidivism, or the failure of the law to successfully cope with a repeated offender, are of vast sig nificance for us in America. Twenty or thirty years ago almost the only explanation offered for the career of the delinquent or criminal was comprised in the term "degeneracy." The criminal man was the degenerate man; and under the influence of the positivist school, volume after volume was produced descriptively setting forth the characteristics of the delinquent man, woman, and child, as if one were dealing with a certain species or subspecies of human beings. But in the really remarkable developments of the last two decades all this has been changed. Much more has been learned of the nature of mental disease, and vastly more, particularly through psychological studies, of the nature of mental defect. And these two principal divisions of mental abnormality, mental disease and mental defect, are being studied every day more and more in their relation to delinquency and crime. Now there is no need whatever for exaggerating the extent of the correlation between mental abnormality and delinquency. It must be confessed at once that enthusiasts have indulged in rash and ridiculous statements in connection with their earliest studies, par ticularly with the first introduction of the use of mental tests. And there have been people, including lawyers, who have been willing to state that " crime is a disease " and ergo the criminal is a dis eased man. But all such sweeping generalizations are worth little. Judging by the most careful and consistently undertaken studies, the fact regarding mental defect and its relation to delinquency and crime seems to be that among young delinquents there are very many DIVISION OF PREVENTIVE MEDICINE. Vol. XVII. more times the number of mental defectives than is to be found among the general population. The definite percentage varies for different places, of course, and naturally is greater in institutions, when, under probation, the brighter ones are selected as offering the most promise of doing better outside of institutional walls. But under any circumstances, taking cases just as they come in any one of the large juvenile courts, it will be found that at least 10 per cent of the delinquents are mentally defective. We have made very careful studies of several thousand youthful offenders in Chi cago and Boston, and our conservative estimate is that at least 25 per cent of these must be regarded as abnormal mentally. Of this 25 per cent, by far the largest number are to be classified as mental defectives. It is unnecessary to more than mention the classic studies of family groups in this country where mental abnormality and delinquency were closely related —the Jukes family, with the recent restudy of this family, the story of the tribe of Ishmael — an Indiana family, and the Kallikaks as studied by Goddard. The size and importance of the problem is clearly apparent from all this. The percentage of delinquents or criminals who are suffering from definite psychoses varies widely. Figures as published are unfor tunately particularly dependent upon the inclination of the ob server toward some given theory, but in situations where judgments are conservative we still see that there is a very considerable rela tionship betwen actual mental disease and the commission of an antisocial offense. Statistics might be quoted that range from the 2 to 5 per cent of mental disease, which we ourselves have found among young offenders, to the large percentage of even some special mental disease which some observers claim to have found in par ticular court or institutional groups of older criminals. A much wider viewpoint has recently been taken —and very cor rectly taken, I believe —by the exponents of the modern ideas of mental hygiene. It is not only the frank psychoses, the " real cases " of mental disease, and the plain cases of mental defect that are im portant for the students of mental health, but also many other matters that are to be properly classified as unhealthy functioning of the mental life, and matters that pertain to peculiarities of the structural make-up of the mental powers in a given individual, even though there be no feeble-mindedness. By studies in this field we come across the facts of, as well as the causes for, intense dissatisfaction, grudge formations, impulsations and even obessions, mental conflicts, jealousies, emotional outbreaks, urgent desires, and other affairs of the mental life as originating from within or from without, any of which directly cause or directly underlie tendencies toward delinquency. Surely these are matters No. 2. 363 DIVISION OF PREVENTIVE MEDICINE. of the highest importance for therapeutic endeavor under the head ing of mental hygiene. They are matters of the greatest social as well as personal concern. They require study which is only com petently undertaken by persons with a wide range of knowledge of what is available in psychology, normal and abnormal, and of what bears on the given situation in medicine. We have many instances of minor abnormal mental manifestations such as occur during the course of disease, as in chorea, or during a period of life, as in adolescence. School dissatisfactions leading to delinquency—" the kindergarten of crime "—are based upon special disabilities for learning and many other factors in the whole school situation. We have the production of unfortunate mental states as the result of reactions to irritating conditions in home or school life or in employment. And in connection with recreations, or even with reading, we sometimes find the development of a most unhealthy type of ideation. In many ways undesirable mental habits are formed as the result of experiences or inner tendencies. Some of the very deepest emotional upsets are to be observed in normal or even unusually intelligent individuals as the result of untoward happenings experienced at particularly susceptible periods of their fives. Any and all of these, we know from the study of many cases, are conditioning elements at the foundation of careers of delinquency and crime. Observation also shows the immensely fruitful field that there is in all this for the therapeutic approach that the term mental hygiene implies. It is a work for trained specialists with open minds, who know not only the phenomena of mental disease as such, but who are also students of personality, characteristics, and trends, of psycho logical capacities and incapacities that are quite beyond the implica tions of " an intelligence quotient," who are students of all that goes to make the individual (always through the mental life itself) ex hibit unfortunate antisocial tendencies. There are adjustments that can be made with the greatest hope of success in ways that are not at all contemplated by the alienist as implied in his dictum " insane or not insane," " feeble-minded or not feeble-minded" (which amounts to institutional care or not institu tional care), or by the work of the modern psychiatrist, though he deals more carefully than ever with definite psychoses. There may be much more to it for professional work as our science develops. AVe hope for much more, whether it be by glandular therapy, or by study of toxins affecting brain cells, or through other investigations from a physiological or psychological standpoint. But, even as it stands now, the direct, proper, and main avenue of approach to the prob lems of delinquency and crime is through the field which has come to be designated mental hygiene. 108165—22 12 364 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. ASPECTS OF MENTAL HYGIENE RELATED TO ALCOHOLISM AND DRUG ADDICTION. Any one who has even half studied human inebriety must have reached the conclusion that many alcoholics are defective or insane. And one may hold this opinion without being in the least an ex tremist. Neff well writes : " It has quite often been said that all in ebriates are more or less insane or mentally defective, but it is our opinion that when all inebriates of all social grades are classed to gether it will generally be found that the majority are neither de fective nor insane." This statement is merely preliminary to the recognition of a very practical fact for treatment, namely, that a considerable proportion of drunkards are by virtue of mental ab normality not responsive to treatment. Taking cases of habitual and periodic drinkers who have been re peatedly arrested, Anderson found in his court work that 56 out of 100 had a decidedly inferior level of mentality. He considered 37 of them clearly feeble-minded, 7 were insane, 7 were epileptic, and 32 of them showed evidences of an innate psychopathic constitution. This is probably a fair sampling of the chronic offenders in a metro politan court where many arrests are made for drunkenness. No other statement is needed to show the relationship of mental health problems to the social scourge of alcoholism. That another feature is added in very many of these cases through alcoholic mental degeneration, the result of definitive poisoning of brain cells, goes without saying. Drug addiction is an issue before the country at present as never before. In connection with the problem of drug addiction, prob ably the student of mental hygiene is more concerned with the results of the drug itself upon the mental powers than with the original constitutional weakness of those who become drug users, in this respect being a variation from the problem of alcoholism. The fact that some observers working in courts have found evi dences of a considerable proportion of mental abnormality, either defect or psychotic tendencies, is not so significant as in cases of inebriety, because nearly all of these drug users as they appear in court are delinquent individuals involved in other antisocial be havior than the use of drugs. They are either innately so abnormal mentally or have become so deteriorated that they place themselves in situations where they readily come under the ban of the law. Comparatively few of their arrests are for breaking the drug law. As a matter of fact a vast number of drug habitues never come in contact with the law because, of course, their use of the drug does not entail such socially offensive behavior as does drunkenness. The problems of mental hygiene, however, are involved in prac tically every case of habitual drug using even if there is no drug No. 2. 365 DIVISION OF PREVENTIVE MEDICINE. psychosis or any innately defective mental constitution. This main fact constitutes one of the great points of attack in treatment. Mental dissatisfaction itself, for example, whether through ill health or other stress, is one of the prime reasons for entering into and continuing the drug habit. Anyone who would merely attempt to get an understanding of why human beings respond to such artificial stimuli or satisfaction must take into account the facts of mental life. As in the case of the relationship of mental hygiene to delinquency, we see here again the fact that mental health means much more than freedom from a definite psychosis, just the same as bodily health means much more than freedom from specific and well-known dis eases. The student of health must take into account the functioning of the organisms upon levels of efficiency, adaptation, and satisfac tion to the individual —facts that are not usually dwelled upon in textbooks of pathology, either of mind or body. MENTAL HYGIENE AND PROSTITUTION. The studies and reports, some of them very extensive, of the earlier vice commissions which, 10 or 12 years ago. first undertook the diffi cult task of public enlightenment concerning prostitution had very little to say concerning the mental personality of publicly immoral women. The swing from the nonrecognition of the problems of mentality involved to the most exaggerated statements concerning the amount of feeble-minded and psychopathic conditions to be found among these women was the natural swing of the pendulum. The real situation seems to be about as follows : Of course, no one who knows the facts would presume to argue that such immorality entered into by women as a gainful occupation is highly correlated with mental incapacities of any kind. The only studies of mentality that have been made are of those women who have been so foolish that they did not avoid the notice of the police or other preventive agencies, or, more rarely, of some groups of those who have been openly and notoriously plying their trade and have been willing to be studied. Even the superficial investigations of vice commissions show that a vast amount of prostitution is engaged in by women who are sharp enough to keep out of public notice and to avoid showing any evidences of law breaking. There is no reason to believe that these women differ in mentality from the average run of the popu lation. But through the study of women who are easily accessible, be cause of open immorality or being under arrest, we get a picture that demonstrates clearly a very considerable correlation between mental abnormality and such " caught offenders." In the opinion of the Massachusetts Vice Commission, about half of the women 3G6 DIVISION OF PREVENTIVE MEDICINE. Vol. XVII. seen were to be considered as mentally defective. It is of local interest that Anderson, taking 100 women who were seen in his laboratory in the Boston municipal court, found that about half of them represented pathological mental types, among which feeble mindedness ranked highest. But here again we have the fact that many of them evidently came to attention as violators of the law because they were alcoholics or drug habitues. Indeed, some of them had already begun to show deterioration from these poisons. The point of the whole matter is that no individual or general social therapeutic or preventive treatment of prostitution can be considered, even in terms of common sense, without reckoning on the highly practical human factors of mental conditions as they most necessarily affect prognosis. The problems of illegitimacy are to some extent the same as those of prostitution. Here again it is clear that the brighter individuals take care of themselves and of their offspring in ways to avoid public notice. But a study of cases of illegitimacy as they come to public agencies reveals a very considerable percentage of mental abnormality among the mothers. Probably the best source of in formation for readers of this bulletin is Kammerer's " The Un married Mother." MENTAL HYGIENE AS RELATED TO VAGRANCY AND DEPENDENCY. It is easy to understand that the vagrant or tramp very frequently indeed is a psychopath. The fact of his lack of success or of find ing satisfaction under ordinary conditions, when, as is usually the case, he has a fairly good physique, is evidence of something ab normal in his personality. Of course there are economic reasons, fairly clear at different periods, which must be taken into account in estimation of the causes of wandering or vagrancy. But the study of the ordinary or habitual tramp in this country as well as in Europe, where an important literature has developed concerning the subject, reveals a considerable list of mental troubles in the background of the tendency toward a vagrant life. One mental disease in particular has received considerable at tention as relates to vagabondage, and from observation of indi vidual cases we have no doubt that this disease (dementia praecox) plays an unusually large part in the situation. In the fellowship of tramps—and it sometimes exists to the ex tent that there are tramp colonies —degenerate practices are very frequently carried on which may well develop a tendency toward deterioration, toward living at a lower level than the innate mental constitution of these men would warrant. Apropos of social prevention of the ills that such irregular living implies, it is most interesting to note that in communities where No. 2. 367 DIVISION OF PREVENTIVE MEDICINE. feeble-minded youths and cases of mild psychoses have been taken care of early in greater proportion, there is very much less evidence of vagrancy or tramp life. The problem can be solved —it is solved to a greater extent in Massachusetts, through better cure of the mentally abnormal, than in most States in this country. Much can be done by early attention to the real needs of the. feeble minded, the mentally diseased, the epileptic who lias mental dis turbances, and the psychopathic inferiors. We can find evidence of it in the better control in certain localities of tramp life, pros titution and delinquency. Constructive measure!-: undertaken arc related not only to the welfare of these individuals themselves, but also to their progeny, for, of course, dependency results from the nonsupport and the desertions that are connoted by alcoholism, pros titution, and vagrancy. And much more is involved (ban the eco nomic situation resulting in State care and placing out of children; we have only too frequently the matters of actual disease in these children, physical and mental, which are most costly to our civiliza tion. There is thus every argument for assailing in the most direct way those burdens of our social life which come under the head of delinquency, alcoholism, drug addiction, prostitution, illegiti macy, vagrancy, and dependency through an approach to them which can only be gained by knowing their intimate relationship to the facts of mental hygiene —through understanding what each of these means in terms of departure from mental health. NOTES FBOM THE NAVAL BASE, HAMPTON EOADS, VA. Newly eidisted recruits began to arrive at the naval training station on the 20th. As has been the custom for the past year or more, all of these men have been very thoroughly reexamined physi cally by a medical officer; including an examination of urine, which is not customary, I think, at other training stations. This procedure has brought to light more than a dozen men, having albumin per sistently present in their urine. These men, of course, have been held up, transferred to sick quarters and placed under observation. The functional efficiency of their kidneys will be determined, and, if found necessary, they will be surveyed. Other defects, principally heart disease, have been found in various recruits. Surveys have already been held upon those who are not physically fit for the service. We are proceeding on the assumption that the Navy re quires only men as nearly perfect physically as it is possible to obtain. 368 Vol. XVII. DIVISION* OF PREVENTIVE MEDICINE. SANITATION DIVISION. The work of mosquito prevention has been vigorously carried on during the month, and all breeding places, both on the naval oper ating base and the Virginia Terminal property, have been kept thoroughly covered with larvaecide. The prevailing heavy rains have made the work of mosquito prevention quite an undertaking: but by directing most of the time and attention of the division to ward this particular work, the situation has been kept well in hand. Instead of the routine inspections that have been carried out liere- tofore, inspections have been made to determine the probable breed ing places of mosquitoes and flies. All places that were, or could possibly become, breeding places for these pests have been covered with larvsecide. NOTES FROM THE UNITED STATES NAVAL TRAINING STATION, SAN FRANCISCO, CALIF. The general admission rate for the month of May was 634 per 1,000 per annum as compared with 899 per 1,000 per annum for April. There were but two admissions for communicable diseases: one with diphtheria and one with tuberculosis. About 20 per cent of all hospital corpsmen are found to be car riers of the organisms of Vincent's angina, usually with minute lesions of the gums. The same condition applies to the personnel of the Hospital Corps training school. Active treatment of lesions, disinfection and in appropriate cases isolation is practiced. NOTES FROM THE NAVY MINE DEPOT, Y0RKT0WN, VA. During the month of May a bacteriological examination of the water supplied to this station was made and it was found to contain B. coll. No chlorine was being used at this time, as the supply bad been exhausted. Upon investigation of the watershed it'was found - that a number of laborers were working around the group of springs supplying the water mains, and that there was a small amount of pollution of the hillsides around the springs. Rigid regulations were instituted at once to prevent further contamination, a supply of chlorine was secured from a neighboring Army camp, and every one concerned was advised by a station notice to boil the water before using it for drinking purposes.

(d) Bureau's letter No. 124842(103) of Feb. 14, 1922. 1. In response to reference (rf) seventeen reports were returned from the commands to which reference (c) was referred. Nine of the reports received expressed concurrence with the hoard's recommendations. 2. The following is an abstract of the criticism received and grouped under each form considered : (a) N. M. S. Form No. 10.—" Recommended that the following be added Im mediately after absentee report (reverse side) : Mast report. Name : rate : offense : date, etc. : Remarks. This gives the commanding officer daily information as to all mast reports, awaiting-actiou cases, etc. (I'earl Harbor.) "Daily personnel report, which should contain more than twenty-one wards" (Great Lakes). " This form as submitted is incomplete in that summary does not show num- Ikt of patients died, deserted, in confinement, on leave, or absent without leave. Summary should also show number of hospital corpsmen on duty, in confine ment, on leave, or absent without leave."- (Norfolk.) " It is recommended that ' Changes in staff ' be made a seperate report in stead of being printed on the back of the ' Personnel report.' The data for the changes in staff and the absentee report is, at a large hospital, more efficiently handled at a desk other than the one handling the personnel report, and. due to the delay often occasioned by definitely determining the absence of an indi vidual, the distribution of the personnel reimrt would be unnecessarily de- • layed." (New York.) (6) N. M. S. hospital Form No. 3.—"Horizontal lines are not practicable in that copies seldom agree with original when inserted on typewriter, due to faulty printing. An unruled page, allowing names to be typewritten single spaced, will permit listing of twenty or more nnmes instead of ten as on sug gested form, an item of interest to large hospitals. Space allotted to listing of service records, health records, and pay accounts should be reduced, thus permitting long names to be written in full followed by service number. Num bering of lines is not necessary." (Norfolk.) (c) lia-ggage cheek. — " In order to render this check more difficult to change or counterfeit in the case of loss, more important as a means of identification 370 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. to the owner and to better serve Its purpose as a baggage check, it is recom mended that both the tag and its stub be numbered consecutively in conspicuous type." (Newport.) " Recommended •that first action section of stub have space for patient to sign ns receipt. Stub to be filed by baggage man for future reference in case a claim is made for baggage or missing clothing after patient has left hospital. " U. S. Naval Hospital " All personal property received this date " Witness : " Bagroom keeper." (Pearl Harbor.) " The advantages of this form believed to be of a doubtful nature. Experi ence at this hospital has demonstrated that only constant watchfulness on the part of the corpsman detailed in baggage room will prevent thieving, and it appears that the loss of baggage check and consequent finding of it by another person would tend to give the finder access to baggage not his own were he inclined to be dishonest. The above remarks are based on the assumption that the possession of the detached part of the tag will gain access to baggage indi cated on the check. It is suggested that the service number or some other form of a check appear on the original check (not on the duplicate) that can be furnished only by the bona fide owner of the baggage." (Charleston.) (d) Change of diagnosis. —"This office recommends adoption of attached standardized forms with alteration of " Notice of change of diagnosis " to read as follows, due to the fact that patient might be carried with a diagnosis other than the one with which admitted to hospital : Diagnosis changed j ^^'.m ' (Annapolis.) " Recommended space be provided for approval by executive officer in smaller hospitals, or by supervisors of medicine or surgery in the larger hospitals. Eliminates mistakes (technical or otherwise) by junior inexperienced medical officers and keeps immediate superiors familiar with status of patients under their supervision. Authorizes personnel office to make necessary record changes." (Pearl Harbor.) "A similar scheme in the form of a memorandum has been tried out in this hospital and has not met with success. A book kept in the record office and accessible to medical officers is believed to give results and such book is now being used as an experiment in this hospital. Too often the card fails to reach the record office and only a constant check of health records insures the form ' F ' card being closed out and a new one for the new diagnosis opened. The book is believed to provide a more stable record." (Charleston.) (e) Operations scheduled. —" It is believed that if space were provided on this form to show the ward to which patients to be operated on are assigned, it would aid in proper distribution of the several copies where more than one ward is concerned." (Charleston.) " Suggested that the word ' anesthetist ' be added to the heading anesthetic. In most hospitals where there are several anesthetists, the above additional information assures equal distributiofi of this duty and gives necessary pre paratory information." (Pearl Harbor.) " Operations scheduled " should contain several more spaces for names." (Great Lakes.) "That all new forms recommended in paragraph 7 be adopted except (b). It is believed that the ' Operations scheduled ' in its present form could be omitted or modified for the following reasons: " First. Emergency cases could not be planned in advance. " Second. Operating surgeons must be allowed leeway as to what anesthetic is to be used, as the case comes to operation. " Third. With a senior operator and several assistants, it is impossible to tell in advance which assistant would be given the opportunity to do routine work as the need for post-operative watching of a patient, and other condi tions will modify the schedule. " Fourth. Under present conditions most operating surgeons are men of sufficient experience to be trusted with the details of the work they are doing, and I believe all hospitals now have in effect some form of official approval of work planned, but not in such detail as indicated. No. 2. 371 DIVISION OF PBEVENTIVE MEDICINE. •' Fifth. A schedule such as proposed would be constantly changed, either by additions or omissions, depending upon changed condition of patients. It would soon, of necessity, degenerate into a perfunctory, useless formality. " Sixth. Many times the ' Professional assistant to the executive officer ' or the executive officer has followed a case more carefully than the command ing officer, and the determination to operate, or not to operate, can be better decided by him than by the commanding officer. As a matter of fact, a majority of ' approvals ' are in the nature of taking the recommendation of the ' Professional assistant to the executive ' or the operating surgeon. " Seventh. In most cases it would be as important for the commanding officer to give his approval for instituting radical treatment in medical cases as in the ordinary run of surgical eases. The question of venesection, the use of oxygen, and the more powerful forms of medication, are not ordi narily referred to the commanding officer for approval in advance, nor do I believe the average run of surgical cases need approval." (San Diego.) The following are the views of the board regarding the above comments : (a) N. M. S. hospital Form No. 10.— Inasmuch as the regulations require that a special report book be kept, which report book contains entries of all disci plinary refractions, further entries regarding this subject are deemed out of place on this form. In order that more space for wards be allowed without increasing the size of the form, it is recommended that the horizontal lines be eliminated from the form as originally proposed. This will permit any probable number of wards to be enumerated. The present form, if correctly made out, would show the disposition of all personnel in the body or' the report. It is, therefore, recommended that no addition be made to the " summary of patients," since the aggregate of change in personnel of the day is believed to be sufficient for requirements. A com plete dally summary for hospital corpsmen is believed to be unnecessary, as daily changes are infrequent and a weekly report is already in existence. The recommendation of the New York hospital as to dally changes in staff would necessitate a new form, which Is not recommended. (b) N. M. S. hospital Form No. 3.—The board concurs In this recommenda tion and recommends its adoption. (c) Baggage check.— The proposed form provides for a storage number. Receipt of patient for baggage is covered by Form " G " when his signature Is obtained on discharge or transfer, Form " G " should be filed in his jacket, thereby being made available for any future correspondence covering the sub ject. The board believes that the duplicate checks should be in the custody of the ward nurse and not carried by the man concerned on account of possibility of loss. The nurse Is in a better position to identify the man than the bag room keeper. (d) Change of diagnosis. —The recommendation of Annapolis Hospital is concurred in. If a hospital demands that this report be signed by the executive officer or supervisor o>f a department, this may be accomplished by having the proposed report initialled by the officer concerned. It is the apinion of the board that while several hospitals are now using this form (which is believed to be adequate and its adoption recommended for this reason), nevertheless it would appear that the best procedure would be to return the health record at the time the change is made to the record office so that it may be checked by officers concerned and the record office. A book for this purpose is not recommended. (e) Operations scheduled. —The form as proposed is for the official notifica tion and approval of an operation by the commanding officer and does not abridge any of the prerogatives of the operating surgeon with respect to pro fessional judgment. Other suggestions not concurred in. 4. Copies of all forms recommended are appended. F. E. McCuix-otjgh, Captain (M. C), 17. S. N H. W. Smith, Commander (U.C.), U. 8. A". H. L.

WOUNDS OF THE KNEE JOINT: THEIR SURGICAL IMPORTANCE AND TREATMENT, WITH SPECIAL REFERENCE TO THE METHODS DEVISED AS A RESULT OP THE GREAT WAR FOR THE TREATMENT OF SEPTIC KNEE JOINTS. By C. M. Oman, Commander, Medical Corps, United States Nary, and E. J. Cumjtikgs, Lieutenant, Medical Corps, United Stales Navy. This article was prompted by a case of knee-joint injury followed by severe infection that came under our care several months past. Happily the outcome has been good, and the patient is now well and walking with a good functional result. The surgical importance of injuries of the knee joint has been impressed upon us by the cases which have occurred in our practice as one of special concern and interest to the naval surgeon. It is necessary for us to draw freely from literature, giving a short epitome of the management and treatment of wounds of the knee joint as developed and outlined by men of large surgical experience and skill who have specially treated and studied these types of cases. It is our purpose to present to the surgeon, in a simple way, the best methods that have been devised in the treatment of these injuries and their attendant complications. In order to present the subject as a basis for our application of these methods in peace-time military surgery or civil surgery we will have to refer to the contributions made as a result of the war on the surgery of the knee joint. The wounds of the knee joint in military surgery in times of peace and in civil surgery will vary in several respects from those of war sur gery, but the fundamentals of surgical circumspection and treat ment remain the same. Surgery of the knee joint has always been a difficult and hazardous problem, due largely to the great size of the joint and its peculiar anatomical conformation. Infection of the knee joint is doubly hazardous and vexing on account of the recesses and pouches within the joint that act as reservoirs for the collection of pools of pus, pro hibiting the accomplishment of proper surgical drainage and threat ening the patient as to life and limb. It is the consensus of opinion 379 380 OMAN AND CUMMINGS—WOUNDS OF THE KNEE JOINT. Vol. XVII. among all surgeons, American and European, who handled large groups of gunshot wounds of the knee joint, that these injuries are very serious. If the joint becomes infected as a result of injury, the outlook for the patient becomes serious, first, as to life; second, as to limb; and, third, as to function. It can be readily seen from these few facts that the surgeon who is confronted with any injury of the knee joint has a formidable situation to handle. In the various studies made by different surgeons on the groups of these injuries some very interesting and instructive data have been collected and some good deductions and lessons have been drawn. Kellogg Speed published an article in which he gives an interesting general collection of knee injuries as made by H. G. Barling, in the Rouen Hospital district, from June to December, 1916. Barling discovered that the statistics clearly revealed a high proportion of patients whose wounds required early excision, re moval of the damaged bone and any retained foreign body, joint irrigation and closure by suture, and which later followed a course of satisfactory healing requiring no further surgical interference. The findings in 845 knee joints operated on in the Kouen district are presented, as follows: ■ Results of 845 operations on the knee joint. Classification of wounds. 1. Total number cases of injury to knee operated on 2. With bone injury 3. Without bone injury 4. Wound excised and closed 5. Cases under (4) requiring further operation 1 6. Wound excised and packed 7.

It will be noted in this group that of the 322 wounds that were excised and closed 82, or 25.5 per cent, required further operation, indicating that 74.5 per cent got well without further surgical pro cedure. Of the 336 wounds, however, that were excised and packed 38.4 per cent required further operation, only 61.6 per cent getting well without further surgical procedure. This shows clearly better results following excision and closure. The total amputations num bered 164, about 20 per cent of the cases, or one-fifth of the number, No. 3. OMAN AND CUMMINGS—WOUNDS OF THE KNEE JOINT. 381 a rather high percentage, as later improvements and different treat ment in the management of these cases shows. The mortality of 8.5 per cent is rather high, but we must bear in mind the serious char acter of the injuries and the lack of any uniform or conclusive method of handling or treating these cases at that time. Kellogg Speed in a series of 85 cases had but 2 deaths, 1 death not as a direct cause of knee injury but from a gas infection of the arm. The amputations numbered 9, or approximately 10 per cent, a much lower ratio than that of Barling. Out of the 85 cases 65 were treated as nearly as possible by wound excision and joint closure, leading to 55 fair to excellent results, which again shows the advan tages of early excision and closure. Of the 65, 6 suffered amputation, 2 died, and 47 wounds healed cleanly, demanding no surgical in terference. The general results of the series of 85 cases were excel lent in 25 instances, good in 36, fair in 13, loss of limb in 9, and death in 2. He makes an observation that is noteworthy: We might believe that the result depends not so much on whether a wound is penetrating or through and through as it does on other factors, namely, early surgical excision and the presence or absence of concomitant bone injury. His operative technique is given as follows: First comes careful skin shaving and disinfection. The leg should be held up off the table by an overhead swing. Second, the track of the missile is completely, carefully, and slowly excised with a sharp scalpel, but no scissors. The sliding of the tissues over each other is avoided and the contused edges are removed in one piece. Sufficient skin opening is made to permit access to the for eign body on the joint surface. Fresh towels and instruments are then procured. No fingers or instruments are inserted through the wound into the joint, since not only may infection be carried in but the foreign body may be pushed into an inaccessible area. The com minuted bone and foreign bodies are removed. The synovial sur face should not be sponged or irritated or exposed for any longer time than necessary. It matters little about the length of the skin incision, but the amount of skin removed should be sparing to avoid '.indue tension in the closure. Skin plastics may be performed. If the foreign body is buried in bone, it its removed and with it the surrounding damaged bone. Third, the joint may be irrigated with physiologic sodium chloride solution. Various operators use ether, flavine. proflavine, or eusol. As far as we can tell, the solution used makes little difference. Mechanical cleansing without joint trauma is desired. Fourth, the wound is closed in layers. The synovia is closed by stitching to bring only smooth surfaces in contact and the skin and superficial tissues are closed snugly, unless there is great edema and contusion. In that case a small drain may be put down to the closed synovial surface, not into the joint. If the synovia 382 OMAN AND CUMMINGS—WOUNDS OF THE KNEE JOINT. Vol. XVIL can not be closed, a gauze pack is placed down to its surface. In jection of formaldehyde solution, glycerine, ether, or other irritants into the closed joint is of doubtful value. Fifth, a Buck's extension is attached to a Thomas splint on the leg, and flannel bandages cover all. For comfort and steadiness the application of the splint should be exact, requiring skilled attention. Most patients should be re tained from 24 to 48 hours before transportation. Dressings and splints are not disturbed unless there is pain, fever, or looseness. We introduce this for your study that you may compare it with the technique of Willems, as given later. It might be well to state with reference to after treatment that when Speed finds aseptic healing is in progress and the joint is not painful slight passive mo tions may be started in the second week. In an article on knee-joint war injuries, McWilliams and Hetzel state that Willems (a Belgian surgeon) gives the following statistics in regard to the final outcome of 100 of his consecutive knee cases, 18 of which were accompanied by a purulent synovitis of a virulent type, chiefly streptococcus. In the 100 cases there were no deaths and no amputations. There was one resection and two stiff joints. These are very striking results and stand in profound contrast to the reports we have just studied of Barling and Speed. The following are the general principles of Willems's treatment as given in the article of McWilliams and Hetzel : Preliminary Roentgen ray examination of the joint with the object of determining the degree of fracture, if any ; also the marking out on the surface of the posi tion of the foreign body beneath. At the operation careful debride ment of all the damaged tissues surrounding the wound, external to the opening in the synovial membrane, and the removal of all the hemorrhages in the fascial planes about the wound. Changing of the instruments, or resterilization before entering the wound. Re moval of the contused edges of the synovial wound with its enlarge ment up and down sufficiently to do the necessary subsequent work. The joint should be kept open just as short a time as possible in order that the synovial membrane may dry as little as possible, since a dry synovial membrane seems to predispose to ankylosis. Removal of the foreign body, all clothing, and loose detached bone fragments. Smoothing off of all rough bone edges. If the foreign body is buried in the bone, it is chiseled away, following the tract to its end and re moving all the devitalized bone surrounding the tract. If possible, all the procedures should be performed without the gloved hands being introduced into the joint, or without touching any contacting part of the instrument to be introduced. At this stage, one will de termine whether there is sufficient undamaged articular cartilage left to make possible the hope of subsequent restoration of function by immediate, post-operative, mobilizing movements. The joint is then Ko.3. OMAN AND CUMMINGS—WOUNDS OF THE KNEE JOINT. 383 thoroughly washed out with any nonirritating, bland solution, such as Dakin's or normal salt solution, followed, finally, by a flushing with pure ether, and then the capsular opening edges are completely closed with a plain continuous catgut suture either through and through, or, as some prefer, so passed that no suture appears inside the joint. Unless the effusion into the joint is frank pus, as in neglected cases, the synovial membrane is completely closed, disregard ing the length of time that the injury has existed prior to the opera tion. The tissues external to the closed capsular wound need not be closed, however, and had better not be, if the injury has existed over 12 hours. The external open wound may be loosely packed with gauze, wet in Dakin's solution, or Carrel's tubes may be placed in position in the wound for subsequent treatments with Dakin's solu tion. The important point to be emphasized is that the entire open ing in the synovial membrane must be completely closed. A bandage is so loosely passed about the dressing as not to impede subsequent movements. At the time the joint is open, a culture is taken of its contents to subsequently determine the presence or absence of hemolytic strep tococci, which, when found, requires speedy drainage of the joint. No splint to be applied, and this is all-important. After treatment. —Just as soon as the patient is out of the anaes thetic he is made to actively (never passively) move the articidation in bed. Passive motions are painful and set up an inflammatory reaction, and later on an extra-articular abscess may be caused to rupture into the joint. The patient's hands grasp the sides of the thigh, which is lifted from the bed by muscular contractions, his heel remaining resting on the mattress. At first there is excessive fear of trying these motions, but as the pain is felt to be very slight, courage is soon established. The sooner motions are begun after the operation, the less is the pain, because the periarticular struc tures do not have time to become infiltrated with exudate. The nurse sees that this is done every two hours, night and day, to the greatest extent possible short of actual pain. To the faithfulness, consequently, of the nurse in following these instructions will be due the subsequent restoration of function. There is astonishingly little pain when active motions are started immediately after the operation, providing no bony fragments are displaced, in which case move ments are not indicated. Patients say that if painful sensations appear during repose the best means of making them disappear is to repeat the movements. Willems's treatment of a wound of the knee joint may be briefly outlined as follows: (This summary was taken from the article by Burton James Lee.) 1. Accurate foreign body localization. 384 OMAN AND CUMM1NGS WOUNDS OF THE KNEE JOINT. Vol. XVII. 2. Careful debridement of all soiled and devitalized soft tissues and soiled bone. 3. Removal of all loose bone fragments and foreign bodies. 4. Irrigation of the joint with saline. 5. Filling of the joint with ether. 6. Primary closure of the joint by suture, usually including the skin. With considerable injury to knee or muscle, it is wiser to close the joint capsule, but leave the skin and muscle unsutured. 7. Early and frequent repeated active motion of the knee, no splint being applied, save with massive bone injury. This mobilization is begun upon the second day, and is continued at two or three hour intervals. The patient is up about the ward, with crutch support, on the fourth day, and is encouraged to walk without any support by the tenth day. We have not had access to the original article of Willems, but his methods have been so thoroughly described and presented by other experienced surgeons that we feel that reference to the original article is hardly required. In connection with the progress of the case following closure, it should be noted that effusion into the joint sometimes occurs. Effu sion into the joint at once puts a stop to the movements, and as soon as the liquid is withdrawn by puncture, mobilization instantly is reestablished, which means that it is not the wound which abolishes the function but the articular distention. Should the joint become distended, should temperature rise and sepsis seem to be starting, an aspiration may be performed to decide the character of the intra articular fluid and to obtain a culture. Staphylococcus infection is less to be feared than streptococcus. Objections to aspiration are found in the wounding of the synovial surface and leakage of the infected joint contents through the puncture hole into poorly resist ing periarticular tissues, resulting in a rapidly spreading sepsis. The joint surface has more resistance than the periarticular tissues. In the cases of septic knee joints, Willems manages them in the following manner : As soon as frank pus is evident, either by signs of inflammation or bacteriological examination, thorough drainage must be at once established by vertical external and internal ex cisions. The joint is washed out thoroughly with Dakiivs solution at the time of the operation. Tubes had preferably better not be used at first, but may be later if drainage is found to be insufficient. When they are used, the internal ends should project just inside t\vt synovial membrane and no farther. The after treatment is conducted exactly as in the case of noninfected joints, by active (not passive) motions carried out to the point of pain. These are begun imme diately after the anaesthetic has worn off and are repeated every No. 3. OMAN AXD CUM MINGS— WOUNDS OK THE KNEE JOINT. 385 two hours thereafter, day and night. Even a day's delay will preju dice the final functional result. Walking is important because the muscular contractions compress the joint and cause a marked in crease in the expulsion of pus. The patient is made to walk the next day after the operation without crutches. It is surprising how much pus will exude from the incisions after each walk. It is very important that sufficient drainage openings be made to allow for an adequate escape of the pus. These openings should be sutured just as soon as the discharge becomes serous. If the active motions are performed often enough and vigorously enough, these secretions are expelled through the drainage openings as they are formed. Drain age seems to be more thoroughly accomplished by this method than by any other, thus limiting the infection to the synovial membrane, and tending to prevent its spread to the cartilage and bones. In civil injuries the results of operations with debridement, joint closure and immediate subsequent mobilization should be much bet ter than in war injuries, because ordinarily the patient is operated upon more quickly, the infection is not so virulent, there is no trans fer to another hospital ; and, finally, the after nursing should be more effectually done. This method of treatment is in absolute contrast with the usual teachings regarding infected joints where immobilization for a long period has been the rule. However, the distinct advantages derived from active mobilization of septic joints prove its value as a sound form of treatment. By mobilization, efficient drainage of the joint is established, the time consumed in recovery is much shorter, and the percentage of good functional results is much higher. Mayo Robson and Kellogg Speed devised a form of drainage for septic knee joints known as subcrural pouch drainage and inver sion treatment. This method consisted in opening the joint in the subcrural pouch through a small incision through the quadriceps extensor muscle in the midline of the thigh. A tube is introduced through this opening into the joint and the leg firmly held in a Thomas splint. In order to effect drainage, the patient was turned over on his face for several hours several times a day, thus per mitting the exudate to run out of the small opening, which, in this way. became the most dependent point of the joint. The limb may be also held in the vertical position at right angles to the body in the Thomas splint, supported by fixing it to an overhead bar. This position also favors drainage but not as effectively as in the prone position. Speed suggests this treatment for the first stage of knee-joint infection and even for those that threaten to become severe. In reviewing the methods and reports concerning the management of knee-joint injuries, with their attendant complications, it ap 386 McCOY SOME FEATURES OF PLAGUE. Vol. XVII. pears that the technique adopted by Willems, followed by immedi ate active mobilization, is the standard to follow. Many able sur geons practiced the principles of wound excision and joint closure, but to Willems belongs the distinction of having practiced with marked success the principles of active mobilization in noninfected and infected knee joints. The splendid functional results following the conduct of this principle insures its adoption in the prescribed treatment. We have purposely refrained from introducing into the article a discussion of knee-joint injuries complicated by severe bon»? injuries. The subject is too vast to enter all its phases, hence we have confined ourselves to a discussion of the early treatment shortly following injury and when complicated by sepsis. BIBLIOGRAPHY. A. W.

SOME FEATURES OF FLAGTJE.' By Surgeon (,'eok«k W. McCoy, United States Public Health Service. INTRODUCTION. As there are excellent treatises on plague I shall not attempt tc cover the Avhole subject, leaving out of consideration in general the history, clinical manifestations, and pathology, which can be found without difficulty, and devote myself more particularly to features which are not usually stressed or which are not so readily accessible. There are two main clinical and epidemiological types of plague in man, but so far as we know but one type occurs as a natural infec tion in rodents. The two types in man are the pneumonic and bu bonic, and ordinarily these breed true, i. e., pneumonic plague gives rise to pneumonic plague, is not associated with this disease in ro dents, and for practical purposes may be said never to give rise to cases of the bubonic type. Primary bubonic plague frequently pre sents secondary pulmonary manifestations, but, with rare exceptions, never gives rise to cases of the pneumonic type. ■A lecture delivered at the Vnlted States Naval Medical School, Washington. D. C Xo. 3. 387 McCOY- SOME FEATURES OF PLAGUE. A third class is sometimes recognized, the septicemic type, but careful post-mortem examination will usually show deep buboes in these cases. In general, pneumonic plague is a disease of cold countries, and the little we know about it is derived chiefly from Manchurian ex perience; while the bubonic type is a disease of warm climates or warm weather in temperate climates. In this connection it may be noted that, while the. lung type prevails almost exclusively in north ern China, in southern China it is almost unknown, and the more usual bubonic type is quite common. Inasmuch as the pneumonic type does not appear to have special significance for us in the United States, my remarks will principally be with reference to the bubonic type. The present-day importance of plague is indicated by data taken from the Bulletin of the International Office of Public Hygiene at Paris, which catalogues plague for 1921 at the following places: In Africa: Eastern English possessions, Algiers, Angola, Cape Verde Islands, many provinces in Egypt, Anglo-Egyptian Sudan, Lybia, Madagascar, Senegal, Tunis, the Union of South Africa. In America two cases of human plague of squirrel origin were re ported from California, and, though they are not reported, it should be stated that a number of cases of rodent plague have occurred in Gulf coast cities and in three States in Mexico. In South America the list includes Argentine Republic, Brazil, Chile. Ecuador, Peru, Paraguay. In the West Indies, Porto Rico infestation is shown in six locali ties. In Asia : Ceylon, China (including Hongkong), British India, East Indies, French Indo-China, Asiatic Russia, Siam, the Straits Set tlements, Turkey in Asia. From Europe, infection was reported during the year at three points in Greece, five points in Italy, in Portugal, in the Azores (Portuguese possessions), in Russia, in the new State of the Serbs, Croats, and Slovenes, and in Turkey. In 1920 an outbreak of some thing like 100 cases occurred in Paris and there were infections in at least one of the French seaports in that year. From the Pacific islands, Australia and Hawaii reported cases. GENERAL CONSIDERATIONS. While the list of places in which plague has prevailed within the last year may give the suggestion that in these modern times it is a serious menace, yet we must class it with the other diseases which are yielding to the advance of civilization and to progress in sanitary science. To justify this statement one has but to read the history of plague in England, where for a period of about 600 years ending with 388 McCOr SOME FEATURES OF PLAGUE. VoL XVII. about the beginning of the eighteenth century, plague was present and existed as a serious menace, and to compare this with the occasional trifling outbreaks which have occurred in the British Islands in the last 20 years. In the earlier centuries, the deaths from this disease for many years were numbered by the tens of thousands, while in more recent years these cases may be counted by the dozen only. In its spread from country to country plague, like other diseases, follows the line of trade; and because trade between countries is chiefly in ships, plague is usually a ship- borne disease. Even where facilities for land transportation would at first sight seem to be su perior to those for water transportation, plague appears to prefer water-borne commerce as the medium by which it shall be carried. I think it is more than a coincidence that the only communities in the United States which have ever suffered from plague are those en joying a considerable water commerce, notably San Francisco, Seattle, New Orleans, Pensacola, Galveston, and Beaumont. Many interior communities, with easy and direct railway commu nication to the places I have named, have escaped infection ; although it can scarcely be said that the measures taken to prevent the spread of the disease were such as would have guaranteed against its exten sion. While we may take effective measures as soon as the disease is found among people, there is every reason to believe that, ordinarily, human cases occur only after rat infection has gained much headway, and during the period prior to the occurrence of human cases there is ample opportunity for spread to other communities. BACTERIOLOGY. Before considering the other aspects of our subject, a few words may be said about the recognition of the plague bacillus. There are few pathogenic organisms more readily recognized or more cer tainly identified than is this organism. For all practical purposes but four culture media are necessary, viz, agar slants, on which it grows as a tenacious, sticky, grayish streak; "salt agar" slants, con taining about 2 per cent sodium chloride, on which, within one or two days, most pronounced changes in morphology occur; broth tubes, which present a delicate surface growth, with dependent fringes: and litmus milk, which is rendered slightly acid by the organism. These features, together with its ability to induce char acteristic lesions in laboratory animals, suffice for the exclusion of other organisms with which, conceivably, it might be confused. Pro tective tests, using the Yersin antiplague serum, may be made as the final diagnostic procedure in an exceptionally important test. Punc ture of a gland with a hypodermic syringe will practically always result, in the securing of fluid for morphological, cultural, and inocu lation investigation. No. 3. McCOY—SOME FEATURES OF PLAGUE. 389 This is an appropriate place to say a few words about plague-like diseases. It should be understood, first, that these occur only in rodents; for practical purposes we may say that there is no plague like disease of man. Of the plague-like diseases of rodents, two may be given brief consideration : Pfeiffer's pseudo-tuberculosis rodent- ium organism produces lesions in guinea pigs which are very diffi cult to distinguish from plague; however, this organism is practi cally without effect on rats and is never found naturally in rats or in man. In the work of the Public Health Service we have not encountered any pest-like organism save Pfeiffer's pseudo-tuber culosis bacillus already mentioned, which is closely related to the plague bacillus— indeed, some workers have regarded them as iden tical. This particular organism confers immunity to subsequent infections of plague. A plague-like disease is found as a natural infection in ground squirrels and rabbits and is caused by a remarkable organism, Bac terium tularense. In squirrels and in guinea pigs, it gives gross appearances which defy the most experienced ; however, cultures on the media used for the plague bacillus are always negative and the infectivity for rats is relatively low, so that if one is on the lookout for it no confusion occurs. This organism seems to be highly patho genic for man but without producing plague-like lesions. It seems to require but a slender basis on which to report an organ ism as " plague-like." For instance, there has recently come to our attention a report of a " plague-like " organism which is described as motile, flagellated, giving a greenish-yellow growth on agar, pro ducing gas in sugar media, and rendering milk acid and clotting it. It also failed to infect animals when rubbed on the shaven skin of the belly. It is difficult to conceive of any organism much further from the plague bacillus than this. PATHOLOGY. With respect to the post-mortem diagnosis of plague, it should be emphasized that the gross lesions are as characteristic as those in any diseases in which we are accustomed to rely on post-mortem findings for diagnosis. I know of no infectious disease, with the possible exception of lobar pneumonia, which gives equally characteristic appearance after death as does bubonic plague. This point is stressed because we are accustomed to receive requests for smears and cultures to enable laboratory workers to become familiar with plague. While cultural investigation may be necessary to clinch the diagnosis with evidence which would convince the most skeptical, for practical purposes the gross pathological appearances are path ognomonic. 646—22 2 390 Vol. XVII. McCOY—SOME FEATURES OF PLAGUE. The tumors in the region of the lymph glands, the bloody gela tinous exudate beneath the skin, the pronounced hemorrhagic ap pearance around the lymph node,' the enormously enlarged and softened bloody gland, all combine to give a picture which is not duplicated by anything else. The examination of smear prepara tions, the making of cultures, and the inoculation of animals may. and perhaps in many cases should be done, but such appearances as I have indicated leave no one with experience in doubt. In laboratory animals, and indeed in the wild rodents where the infection has been studied, the lesions are almost equally charac teristic, although it is not necessary to discuss them in detail. ANATOMICAL PECULIARITIES IN RODENTS. There is a remarkable difference between the lesions of bubonic plague in certain rodents. Perhaps the best contrast is between guinea pigs and rats. While each species presents a bubo, the visceral lesions differ markedly. In acute plague in the guinea pig the spleen is always full of whitish-yellow necrotic foci; in the rat these are not found, but the organ is enlarged and purple in color; on the other hand, in the rat the liver is usually liberally sprinkled with necrotic foci, while in the guinea pig the corresponding organ is generally free from lesions. In the rat there is often a marked, dusky red subcutaneous injection that is most striking, but this is not seen in the guinea pig, and, finally, in the rat we have often a marked serous effusion which is wanting in the guinea pig. Indeed, the bubo is the only lesion found in both species of rodents which are commonly used as test animals. Chronic plague in rats has been thought to be the means whereby plague was carried over from season to season, although the evidence is not very strong. Among rodents, susceptibility to plague extends through many groups. It is mentioned here in order that an exception to the rule may be noted. In our experiments with the rodents found in the far West, no example of immunity to plague was found in any species save the pocket gopher. This little animal, which is very common in California, was, to our surprise, found to be highly resistant to the infection, surviving with regularity doses of highly virulent cultures which were uniformly fatal to other rodents. Perhaps there is a suggestion in this fact for immunity studies. Plague is a disease affecting primarily the rats of cities; but. from the point of view of control, the more obstinate infection among rural rodents is not so well known. Let me refer to several examples : In our own Pacific coast region there is, in the State of California, a squirrel plague focus covering an area of several thousand square So. 3. 391 McCOY— SOME FEATURES OF PLAGUE. miles. It is perhaps 50 miles wide by 150 in length. Since its dis covery some 10 years ago it has been the theater of persistent, intel ligent attempts at eradication, but the results have not been satisfac tory. To suppress squirrels effectively would require an enormous ex penditure on the part of a control agency ; that is, the State or ths General Government, or the practically simultaneous expenditure of larger or smaller sums by individual landowners. Neither condition up to the present time has been brought about ; indeed, after enjoying opportunities of familiarity with the work from the beginning, I am driven to the conclusion that the eradication of this focus is impossible with present resources. Indeed, it may well be questioned whether we would be warranted in spending on this work the large sum that would be required to do the job thoroughly. Human plague of squir rel origin is relatively a rare disease, only one or two cases occurring in a year, and, of course, this is insignificant in comparison with many other diseases. What we. must do is to watch the rodents of adjacent cities and endeavor to prevent their infection from squirrels ; this is readily done by the creation of squirrel-free zones around large com munities. On one of the islands of the Hawaiian group we have a focus of plague of over 20 years' standing among rats, chiefly among the species Mux rattus living in the sugar-cane fields. In spite of eradica- tive measures, which on the whole have been as consistently and ef fectively carried out as is believed to be possible with any reasonable expenditure of money, this focus persists and gives rise to a few cases of plague, usually two or three each year, sometimes with intervals of two or three years between cases. An examination on the ground is necessary to enable one to appreciate the—for all practical pur poses — almost insuperable difficulties attending on attempts to wipe out the infection. Here, as in California, the most we are able to do is to prevent infection of villages and towns, and we must pay the toll of an occasional human case. Within the last few months, a new focus of infection has been found in South Africa, where two rodents, a gerbill (similar to a brush rat) and a multimammate mouse (similar to a house mouse), have been found infected in nature, the discovery having been consequent upon the occurrence of cases of human plague in isolated parts of Cape Colony. The area known to be infected in South Africa is at least 5,000 square miles, and from the point of view of eradication, presents a problem similar to our squirrel plague infection on the Pacific coast. The evidence all indicates that this particular focus among rural- •Iwelling rodents is of many years' standing. The oldest of the infections among wild rodents probably is that of Siberia and Manchuria, and it is the one about which we know the 392 Vol. XVII. McCOY—SOME FEATURES OF PLAGUE. least. Very recently, for the first time, we have reports of animal plague infection among the marmots of Manchuria, although the evidence has long pointed to these rodents as almost unquestionably the source of the outbreaks of the pneumonic type of the disease which according to available reports have occurred almost yearly for a long time, and probably have a longer history than is indicated by evi dence so far obtained. Zoologically the marmot is closely related to our ground squirrel of the Pacific coast, and we have every reason to believe that the prob lems are somewhat similar, although, as I have stated, trustworthy evidence is meager. These foci of plague among rodents of rural regions are all marked by the following features; (1) They are exceedingly widespread. (2) They present more serious difficulties in eradication, if indeed this be possible. (3) They may give rise directly to only a few human cases. This holds for all except the Manchurian focus. Human plague of squirrel origin has several points of divergence from that of rat origin; briefly stated, these are: In the first place, the location of the primary bubo in all, or nearly all, of the cases is in the axilla when squirrels are the source of the infection, while in the majority of the cases of rat origin the primary evidence of infection is to be found in the groin, usually in the region of the femoral glands. The infection from squirrels comes from fleas that get on the hands when squirrels are picked up, while rat fleas do not come directly from the natural hast, but from the ground or from the floor. In the second place, there is a smaller mortality in the cases of human plague of squirrel origin, only about 50 per cent of the cases proving fatal, while a much higher rate ordinarily obtains in infec tions of rat origin. The only hopeful thing with respect to the squirrel situation is the fact that bringing the land under intensive cultivation drives out these rodents. It is uncultivated and largely pasture land in which the ground squirrels thrive in California, and it is among the squirrels of these lands that we find plague prevailing. Among the most difficult things to explain in plague epidemics is the long intervals between the finding of infected rodents. In some of our southern cities several months pass during which many rats are taken without detecting infections; then a plague rat will be taken, and again a long interval, with many negative examinations. In Hawaii the interval is often a year or more. The early English workers laid considerable stress on a particidar species of flea. Loemopsylla cheopus, as the essential agent in the No. 3. 393 McCOY—SOME FEATURES OF PLAGUE. transfer of the disease from rat to man. Further work and accu mulated experience, particularly that in the United States, clearly indicates that other fleas may, and probably do, serve equally ef fectively as vectors; possibly one exception to this should be made; the blind flea of the mouse, Ctenopsylla -musculi, frequently found on rats, appears not to bite man. Some of the work done at our plague laboratory in San Francisco with this flea gave negative results, while positive results were obtained with all other fleas with which we worked. Somewhat later Professor Martin and Doctor Chick got, working in England, practically identical results. IMMUNITY OF RODENTS. While rats undoubtedly serve as the chief agents in the transmis sion of the bubonic type of the disease, they are themselves far from uniformly susceptible. It has long been known that rats in infected regions show rather high resistance to infection ; thus, as much as 20 per cent of the San Francisco rats were resistant after plague had prevailed for a very considerable time. Only recently, however, we have been able to show that rats from communities in which plague never has pre vailed show a similar degree of resistance. In work at our plague laboratory in Pensacola, Doctor Spencer found that rats shipped from Mobile, Ala., where plague has never existed, showed a per centage of immunity comparable to those in infected regions. With respect to ground squirrels, an interesting state of affairs exists in California. The ground squirrels in the sections where plague has never prevailed show an exceedingly high degree of susceptibility, dying promptly with definite manifestations of acute plague, while those secured from regions where plague has prevailed for many years show a considerable degree of immunity. The dif ference is so striking that it leads one to believe that those rodents of this species which have long been exposed to plague have a heredi tary immunity, and perhaps it affords some ground for the hope that in due time the disease may become extinct by reason of the increased percentage of nonsusceptible squirrels. SUPPRESSIVE MEASURES. In each community local conditions will dictate, to some extent, the measures to be taken. The experience gained on the Pacific coast with gray rats and ground squirrels was of little avail when dealing with the black rat of Hawaii, which is found both in buildings and in sugar-cane fields. Similarly, the ratproofing much used in this country is economically out of the question in India. Cyanide fumi gation, much used in southern mills and dwellings, is inapplicable RAYNOR MEDICAL COBPS UNITS. Vol. XVII. in India on account of the loose roof construction which readily permits the escape of gas. In the East Indies, for example, where bamboo is extensively used for building purposes, one of the impor tant measures is to find a substitute for this material which offers excellent rat harborage. Workers in India who have recently made many observations on rat poisons, conclude that barium carbonate is the best ; and when it becomes necessary to vary this, or when it is not available, arsenous acid is to be chosen. The effective dose of the former is grains and of the latter one-half grain. These observers found great variation in the readiness with which various baits were eaten, spiked millet being preferred, rice coming next, and wheat coming low in the list. (Indian Jour. Med. Res.. Jan., 1921, p. 44G. vol. 8, No. 3.) In India attempts at rat extermination have not been very suc cessful, but the account of the efforts leads one to agree with the authors that the fault lies in inadequate means of rat destruction. Ratproofing seems out of the question. (Indian Jour. Med. Res.. Jan., 1921, vol. 8, No. 3, p. 409.) A few words about vaccines and serums: Disposing first of the serum, I majr say that there is no very satisfactory evidence that it is of value. Controlled tests of its therapeutic usefulness have not been particularly satisfactory, although isolated series generally leave the users with the impression that it has done some good. fluffkine's antiplague vaccine has been used for many years; here, too, the evidence is not particularly satisfactory. On the whole, perhaps, it is fair to say that biologic products have, from the public health point of view, no place in dealing with outbreaks of plague. FUNCTIONS AND ORGANIZATION OP MEDICAL CORPS UNITS SERVING WITH THE MARINE CORPS IN THE FIELD. By S. N*. Rainob, Major, United States Marine Corps. THE DIVISION SURGEON AND THE MEDICAL STAFF. In this article an attempt will be made to give an outline and general discussion of the duties and functions of the division sur geon and some of his assistants of the medical staff ; their rela tions to the general staff ; their sources of information ; channels of communication: stations and division of duties; and method of management of the medical troops and units. The duties and functions of the surgeon of a brigrade acting inde pendently would differ from those of the surgeon of a division only as limited by the special functions and actions or movements of the So. 3. RAYNOR —MEDICAL, CORPS UNITS. organizations composing the brigade, the number of medical troops attached thereto, and consequent restrictions of medical functions. RELATIONS AND DUTIES OF THE MEDICAL DEPARTMENT AND SURGEON. The medical department is a supply and technical service of the organization to which attached. Its principal function is the pres ervation of man power throughout the organization and maintenance of activities for prevention of disease, early restoration of the dis abled to duty, and the elimination of the physically unfit. The division surgeon is the chief of this service, and as such is a member of the supply and technical staff of the headquarters of the organization to which he is attached. The medical department as a service, and the surgeon as a chief of service, are not independ ent entities but only part of the whole military machine, with definite functions of an auxiliary nature. As these functions are not included in the primary role of the organization of which they form a part, they as well as the necessities of this service must conform to those of the organization of which the medical department forms an integral part. Supervision, cooperation, and coordination by the organization commander through his staff are essential. The medical service, however, is technical and complex, and such control of it as is assumed by the division commander or his representatives should he limited to that necessary for the preservation of discipline, efficiency, and cooperation, and should not enter into its intracor- poreal structure or technical activities so long as the foregoing desiderata are not affected. DUTIES OF THE DIVISION SURGEON. In general the duties of the division surgeon are the administration and technical supply of the medical service of the division, and the care of the troops. In detail the duties of the division surgeon are as follows : 1. Commanding officer of the medical regiment and medical troops of the division for medical department technical service. (Coordi nated by G-4.) 2. Sanitary inspection and prevention of disease. (Coordinated byG-1.) 3. Collection and transportation of the sick and wounded. (Co ordinated by G-4.) 4.

Harvey, Lieutenant Commander, Dental Corps, United States Navy. With the modern conception of the value of dental diagnosis, it would seem of vital importance that the dental officer should have at his immediate disposal methods for the determination of the vitality of the pulps of the teeth, not only for patients referred in cases sus pected of oral sepsis, but for use in connection with conscientious rou tine dental examinations. Doctor Mayo has said that the next great step in advance in the prevention of disease rests largely upon the shoulders of the dental profession. In this connection, it would seem that methods for determining the vitality of the pulps of teeth are pertinent and should be utilized to the extent of their reliability. If prevention means anything it means the determination in advance of the factors which may cause disease and their elimination if possible. Routine dental examinations should therefore be conducted systemati cally in such a manner that with the minimum expenditure of time teeth which are vital can be so noted and thus practically eliminated from further vitality consideration, while those which are not normal can be checked for further examination. As it is a well-recognized fact that pathological conditions are not to be expected about the apices of vital teeth, a reliable vitality test would at once place in the safe class those teeth which offer the normal response, while con versely it would direct attention to the teeth not so responding. Un fortunately, the dental profession has not at its command a vitality test which offers unerring accuracy combined with absence of destruc tion of tooth substance. Several methods are in use, depending upon the facilities at the disposal of the operator and the thoroughness with which the examination is conducted. The Navy, for instance, does not furnish as equipment dental cauteries, and thus the application of the heat test resolves itself into the laborious process of heating an instrument in the ever elusive alcohol flame, at intervals testing its temperature by its charring action on paper, until the proper tem perature is reached, upon which the instrument is placed against the tooth. This test is a valuable one in its place, but an effort to test an entire set of teeth is a disheartening procedure for several reasons, aside from the time factor. Placing a piece of hot gutta-percha against a tooth has been recommended; this likewise has its good points, but presents difficulties similar to those encountered with the use of a heated instrument when an attempt is made to test more than a limited number of teeth. The application of cold to an individual tooth, either as ice, ice water, or ethyl chloride spray, presents difficul ties at once appreciated by the dental practitioner. As is well known to the dental profession, the X-ray or dental film does not offer evidence upon which a diagnosis of pulp vitality can 404 Vol. XVII. HARVEY VITALITY TESTS. be made, other than in those cases where the pathological condition lias progressed to such an extent in the immediate area of and in connection with the affected tooth as to cause a difference in the density of certain shadows portrayed on the film. Diagnosis by reading dental films should never be undertaken without clinical examination and history; the fact should particularly be borne in mind that only one plane of tissue is portrayed and an area of tissue rarifaction may overlie or underlie a tooth apparently involved in it, when in reality the tooth in question may be vital. It is hardly necessary to call attention to the fact that a radioluccnt area does not necessarily mean a nonvital tooth, and it is a source of satisfac tion to have at hand methods which will help us to speedily determine the actual condition of the tooth by other means. Again, a radio- lucent area may exist in a position not connected with the source of origin, and therefore if X-ray evidence is the sole dependence for the determination of the condition of the offending tooth a vital tooth might easily be sacrificed to no avail. Probably the most reliable methods of testing the vitality of the pulps of teeth are the electric vitality test and transillumination used in conjunction with each other. The former is essentially that of the comparative determination of the amount of electric current necessary to apply to a sound portion of a tooth to obtain a definite response, while the latter method, transillumination, which will be described below more particularly, is based on a comparison of the translucency of tissues enjoying normal circulation with the opaque ness displayed by tissues with impaired circulation. A recent revision of the dental supply table will fortunately place at the disposal of the naval dental officer a very valuable appliance for use in transillumination tests. This is a modification of the straight Cameron light, and might be described as an all-glass tubular dental mouth lamp, the last inch or so of which is curved at right angles to the main stem of the lamp. This results in the light rays being pro jected at right angles to the long axis of the lamp stem. This feature permits of the control of the direction of the light rays in the mouth, and they may be directed onto the surface of a tooth or the alveolar process, the manner and degree in which the light is transmitted through to the opposite side of the tooth or process gives to this method its name of transillumination. A normal vital tooth will transmit a more or less clear pink glow, while a nonvital tooth presents, under the same conditions, a decidedly opaque or dull appearance. The appearance of an individual tooth may, of course, be modified by the presence of a large filling. Not only may the translucency of the various teeth be compared, but by placing the lamp above the teeth on the alveolus in the vicinity of the apices of the teeth darkened areas caused by poor light transmission may be seen No. 3 405 HARVEY —VITALITY TESTS. on the opposite side of the alveolus about the roots of teeth which are surrounded by abnormal tissue. It is claimed that the destruction of hard tissue is not necessary to obtain this differentation between the appearance of normal and abnormal tissue, as the shadow cast by the latter is caused by the increased amount and condition of the hemo globin found in conditions of retarded circulation or blood stasis which accompany pathological conditions. The composition of these lamps has been perfected to such an extent that they may be sterilized by boiling. In 1916 the writer had the pleasure of witnessing a clinic by Dr. Howard R. Raper, demonstrating the use of electricity for the de termination of pulp vitality. The simplicity of the apparatus and method of procedure made an appeal, particularly as the logic of the method was apparent. Parenthetically it may be stated that experi ence has somewhat modified the original impression of the simplicity of procedure, as so often the results of the test are particularly desired on teeth the condition of which present difficulties to its application. After thinking over the theory of pulp response to the electric cur rent, the writer in 1916 pressed into service a cheap 1-cell " shocking machine," improvising an insulated electrode by drawing over the broach holder used as the electrode a piece of rubber tubing, which had the advantage of being renewable after the disintegration inci dental to repeated boilings. It is gratifying to learn that Doctor Raper has recently published a volume entitled " Electro-radiographic Diagnosis," wherein he gives the results of his extensive experience which is of particular value to the dental diagnostician, as Doctor Raper in the practice of his specialty, radiography, has had unlimited opportunity to compare directly the results of the electric vitality test with radiographic find ings, and also to reverse the operation by using the test to substanti ate or elucidate radiographic showings. Although Doctor Raper ad vises against placing reliance on this test for determining any factors except the vitality or nonvitality of the pulp, it has proven in the hands of the writer of value in localizing the cause of pains of ob scure dental origin. The hypersensitiveness of a certain tooth to the amount of current necessary to obtain a normal response in the other teeth of similar class in the patient's mouth, indicating with a mini mum expenditure of time the one which should be viewed with sus picion and subjected to a thorough examination. The crude shocking machine of early use has been replaced by a rheostat made for the purpose of electrodental diagnosis and con nected with the 110-volt lighting circuit. This apparatus is nicely graduated as to the amount of resistance cut out and permits of a gradual increase in the strength of the current, but nevertheless is 646—22 3 406 Vol. XVII. HARVEY VITALITY TESTS. open to the major objection applicable to any apparatus which con veys current from any electric main to a patient—that of the possi bility of a short circuit. In using an apparatus of this kind it might seem an advisable precaution before using each time to test the reliability of the insulation and rheostat by setting the indicator above zero, holding an electrode in contact with each thumb and placing one hand on a metal portion of the chair. The writer is indebted for his limited knowledge of the procedure of electric vitality pulp testing to Doctor Raper. and those inter ested in the technical details he would refer to the interesting text book on the subject recently published. Xo originality regarding the procedure is claimed by the writer of this little article, but it may be of benefit to some to learn of the utility of this method, its limitations and value. First we shall consider it in relation to routine dental examinations. Dental examinations are an important part of a dental officer's service and are of value only in so far as they let no guilty tooth escape. The following is outlined as a method of procedure for the examination of patients not having constitutional symptoms: First, a careful clinical examination of the teeth, gums, and mouth, with charting: second, an examination of the translucency of the indi vidual teeth by transillumination; third, transillumination of the alveolar processes; fourth, electric vitality test for teeth which ap pear abnormal under the transillumination test or are otherwise suspicious: fifth. X rays of crowns, bridges, nonvital and doubtful teeth. The above is modified when the patient has been referred or is exhibiting constitutional symptoms of disease by testing the vi tality of all teeth and radiographing areas from which teeth are missing, and, if the case requires, radiographing all the remaining teeth. Efficient dental service should result in the identification of nonvital teetli in the absence of local manifestations before the patient is aware of their lack of vitality. In connection with the use of the electric vitality test, its limita tions should be borne in mind. For example, a recent clinical exami nation revealed on the distal aspect of an upper molar a large pyor rhea pocket extending well into the bifurcation of the roots; the electric vitality test was normal, but the tooth was recommended for extraction. The principle illustrated is that destruction of tissue from pyorrhea alveolaris do.es no interfere with the test, unless the pulp is involved. The condition is sometimes met where, with more than one canal, one may be septic with vitality remaining in the other canal or canals. In such cases a normal response to electricity may be obtained; but transillumination is usually negative, and in a case with conflicting indications we at once bring to our aid all the facilities at our command for the diagnosis. No. 3. 407 HARVEY —VITALITY TESTS. Doctor Kaper brings out very clearly the value of his test in cases in which radiographs show the apparent involvement of the apices of several teeth. A few minutes usually suffices to determine which teeth are vital and which are actually involved. Also the value in the not uncommon cases where the dental film shows the roots of the bicuspids or molars confluent with the floor of the antrum. Not least is the ability to determine which tooth is nonvital in cases where the area of degeneration apparently involves a tooth which in reality is vital, the cause of the trouble being a tooth near by which may present no evidence of being the offending member. This test would also seem to offer an easily applied one in the very difficult diagnosis of teeth which are adjacent to nonvital teeth, particularly those which are classed as suspicious from radiographic findings. One of the unfortunate limitations is that crowned teeth can not be tested without removal of the crowns. The electrode used in the test should be insulated except at the point, and it should be applied only to sound enamel, as enamel which is undermined with decay or covers a metallic filling gives a response which is not a true index for diagnostic purposes. Large fillings should not be touched with the electrode, as they may convey the current with a disconcerting intensity either to the pulp, to the giims, or adjacent fillings. Allowance should be made in elderly persons for the resistance offered by secondary dentine, and in doubt ful cases it is sometimes necessary to make a pit through the enamel and introduce into this the electrode. For use on nervous individuals, Doctor Raper suggests the moisture contact, which is the water bridge formed from an excess of water or salt solution on the cotton wrapped electrode and the tooth surface placed in close proximity. The recording of the electric vitality test is made by using suit able slips previously numbered, each slip with the figures from 1 to 32. After the number indicating the tooth being tested, place the minimum amount of current necessary to obtain a definite response from that tooth, and a comparison of the figures following; the bicuspids, for instance, should give an approximate index of the normal test for teeth of that class in that individual. Best and Waldron, in an article on " Oral diagnosis and treatment," say : " Vitality tests of the pulps of the teeth are essential in order that a well-balanced diagnosis may be formulated. There are many intances of the death of pulps that are not revealed in roentgeno grams. The tendency for the tooth pulp to undergo degeneration is more pronounced as the patient approaches middle life. This is not a new observation, but a fact that has been known for years. The vitality of each tooth is determined by testing the individual 408 Vol. XVII. GALWEY GAS WARFARE. tooth with the faradic current. This test is of great importance and in no case should be omitted." Machat, on " Pulp Vitality: Modern Means of Determining It (A Process by Exclusion) ," says : "Four years ago, when I first presented my method of diagnosis, I made the forecast that electro-diagnosis would be found indispensable. Now, we feel that a differential diag nosis of the internal conditions of teeth is not conclusive until checked up with the electric current. By electro-diagnosis of a tooth, I mean the reaction of a tooth to a weak current of electricity as compared with a previously fixed index. An index is taken by making contact with the mesial or distal electrode upon the labial surfaces of mani festly normal incisor teeth; the saturation or tolerant point is the guide or index for that individual. The normal index can be as certained by the practitioner in accordance with the instrument to be used for testing. " Finally it should be realized that electro-diagnosis is not in fallible. Like the radiogram, it is not an oracle for every diagnostic perplexity. It is limited in value for those who are unwilling to study its intricacies and wide range of usefulness. On the other hand, when mastered, it is a trustworthy friend. In the last analysis, however, it is only part of a system of diagnosis." GAS WARFARE— THE TREATMENT OF GAS CASUALTIES, EARLY AND LATE.1 By MaJ. W. E. Galwby, O. B. B., M. C, Royal Army Medical Corps. Before the foundations for a rational treatment of cases of asphyxiant gas poisoning can be laid a clear idea must be formed of the causes which are operative in threatening the life of the patient. It is agreed that the seriousness of the case varies with the degree of want of oxygen which is present, and treatment must therefore be directed to prevent the development of this condition or to relieve it when established, and so give the patient time to mobilize his reserves to fight and defeat it. Recent research into the physiology of normal respiration has thrown much light on the causation of and symptoms produced by oxygen want, and in addition has explained such well-known clinical phenomena as periodic or Cheyne-Stokes breathing and orthopncea. It is necessary to refer briefly to the factors which regulate normal breathing to understand the sequence of events in asphyxiant gas poisoning. 1 Reprinted from the Jour. Roy. Army Med. Corps, March, 1022. No. 3. 409 GALWEY— GAS WARFARE. When, on inspiration, the lungs expand to a certain point, expira tion is initiated ; similarly, on collapse to a certain point inspiration begins. The nervous impulses concerned are carried by the vagus nerves, but the reflex itself is controlled by the action of the carbon dioxide in the blood on the respiratory center. A certain percentage of C02 in the blood is necessary to fire off this reflex, and if too much C02 is washed out of the blood—as, for instance, in forced breathing —the subject goes into apnoea until sufficient C02 again accumulates to fire off the reflex. On the other hand, a very small increase in the pressure of C02 in the blood —0.2 per cent—will double the respiratory ventilation, increasing both the depth and rate of breathing. Anything, there fore, which interferes with the normal discharge of C02 from the lungs will bring about hyperpncea. What the respiratory center really responds to when it reacts to increase of C02 is the balance of the hydrogen ion concentration in the blood. To any alteration in this balance the respiratory center is extremely sensitive, and the increased breathing in the presence of increased C02 is an effort of the body to reduce the hydrogen ion concentration by washing out the carbon dioxide. In spite of the fact that different parts of the lung are unequally ventilated, it has been shown that the percentage of C02 in an aver age sample of alveolar air from a normal individual is relatively constant. Though a definite percentage of C02 is normally necessary to fire off the respiratory reflex, it has been proved that it responds to a lower percentage in the presence of lack of oxygen. The first re sponse to this condition is therefore an increased depth and rate in breathing owing to the lowered " threshold value "—as it is called— of CO,. As the condition of oxygen lack develops the next response is periodic breathing unless the want of 02 is considerable, when a condition of rapid shallow breathing is established. When the blood comes in contact with the air in the lungs it takes up oxygen and gives off C02. C02 is much more readily diffusible than 02 and much more can be stored in the body, which has a rela tively small capacity for storing 02. When, therefore, there is interference with respiratory exchange the main" effect is on the 02 intake rather than the C02 output unless there is considerable blocking of air passages which prevents air leaving large numbers of alveoli. To turn now to the tissues. The blood gives up its oxygen in them more rapidly and effectively in the presence of C02: if. therefore, from any cause, as by increased ventilation, the C02 is washed out of the blood, it will then part less readily with its oxygen. If. in 410 Vol. K\'U. GALWEY —GAS WARFARE. addition, the supply of oxygen itself is diminished, the tissues quickly suffer from the lack and their functions are disturbed. A slight diminution of oxygen is more quickly felt and has more serious effects on such organs as the brain, particularly the vital centers, such as the respiratoy, and on the heart. A vicious circle is thus set up; the lesion in the lungs interferes with the respiratory exchange, this in its turn reacts on the vital centers with a resulting diminution in the efficiency of the ventilation of the lungs and the circulation of blood through the body. The circulation itself is regulated in the main by the rate at which the tissues allow blood to return to the heart, rather than by the heart itself, which simply pumps at increased pressure the blood delivered to it. The rate of delivery from the tissues is regulated by— (1) The degree of saturation of the blood with oxygen ; and (2) The degree of saturation with C02 and consequently its reac tion in the capillaries. The capillaries do not merely react passively to blood pressure bu. actively contract and dilate. We have now, I think, sufficient data to understand what happens in asphyxiant gas poisoning and why the serious cases fall into two main groups: (1) Those with purple-colored cyanosis, distended veins, hyper- pnoea, and evident distress; and (2) The gray cases, with pallid lips, shallow breathing, but no distension of the veins and little respiratory distress. The latter being the more serious. Remember the anatomical conditions which occur —the acutely inflamed condition of the air passages, particularly in poisoning by chlorine; the damage to the alveolar epithelium, particularly with phosgene, the engorgement and thrombosis of capillaries with flooding of the lung by cedema. These bring about a condition in which both the pulmonary circulation and the respiratory exchange are interfered with. Owing to the swelling and exudation, oxygen can not get through quickly enough to the blood to saturate it during its passage through the pulmonary vessels. The damage to the capil laries causes leakage of fluid, and, in consequence, the blood is more concentrated and its volume is reduced below the danger point. As the heart fails, there is cardiac inhibition and loss of vasomotor tone. The hyperoxaluria of concentration does not compensate for the anoxaemia due to unsaturation, but does make for stagnation by throwing more work on the heart. A combination of the types of want of oxygen —anoxajmia —which Professor Barcroft describes as the most serious consequences of gas poisoning, are thus brought about: (1) The anoxic type in which the No. 3. 411 GAL.WEY- ' GAS WARFARE. oxygen pressure in the blood is too low, the haemoglobin is not sat urated and the blood is dark; and (2) the stagnant type where, though the blood is normal, it is supplied in insufficient quantity. Besides the lack of saturation of the blood with oxygen, the dis charge of C02 from the lungs is also interfered with, and this is the main cause of the hyperpnoea. The lack of oxygen causes failure of the right heart, which is then unable to cope with the increased work of pumping blood through the oedematous lung. As the right heart fails, the superficial veins become distended, and if there is retention of CO, the capillaries will also dilate. The causes, then, underlying the symptoms of the first group of cases—those with plum-colored cyanosis —are (1) lack of oxygen, (2) retention of CO,, and (3) failure of the right heart. So long as the heart is not losing much ground and the lack of 02 is not extreme the cyanosis will remain plum colored. Owing to bronchitis, emphysema, and areas of relative collapse in cases of chlorine poisoning, there is probably more C02 in the alveoli which are still permeable, whereas in phosgene poisoning the injury to the air passages being less there is less likelihood of retention of CO,, but the lack of oxygen is greater since the alveoli are more damaged. There is, therefore, in phosgene poisoning a greater likelihood of the second type of cases —the gray type. In these the lack of oxygen is more profound and the breathing there fore becomes rapid and shallow. There is practically no hyperpnoea, because the increase of breathing washes out the C02 from the blood. For the same reason there is little distension of capillaries. But the lack of CO, causes the blood to part less readily with its 02 to the tissues. If there is less CO, in the alveoli the blood takes up 02 more readily and the arterial blood will be redder, but since there is less CO, in the capillaries the blood parts with its 02 less readily and the want of oxygen becomes more serious. With an equal degree of deoxygenation of the oxyhemoglobin there is less free 02 in the blood when little CO, is present or when blood is a little more alkaline than when more C02 is present or the blood is a little less alkaline. There has been a considerable amount of controversy on the ques tion of acidosis in cases of irritant gas poisoning. Professor Haldane points out that the increase of circulation and respiration caused by the want of oxygen diminishes the CO, in the tissues and brings about a condition of alkalosis, as indicated by the urine becoming less acid or alkaline and the NH, formation in the body sinking to a minimum. The alkali reserve of the body gradually diminishes; that is to say, the amount of soda available for combination with C02. 412 Vol. XVII. GALWEY-—GAS WARFARE. On the other hand lack of oxygen does produce acidosis, and Pro fessor Barcroft found evidence of acids other than carbonic acid in the blood. How, then, does the subject combat these conditions? In three ways : . ( 1 ) By increasing his ventilation. (2) By increasing his circulation. (3) By the consolidation or shutting off of the injured area of lung. (1) By increased ventilation. —As soon as the oxygen want begins to develop the subject breathes more quickly, partly owing to the fact that C02 has a lower threshold value in the presence of a slight lack of oxygen and partly owing to the stimulus of oxygen want itself. The increased ventilation raises the pressure of 02 in the lungs and reduces the lack of oxygen and tends to stave off its more serious development. (2) The circulation rate is increased, and if a blood gas analysis is made in a patient who is maintaining his position it will be found that the venous blood contains more 02 than normal. This is not because the tissues are using less oxygen, but because the blood is being propelled around the body more quickly. (3) So long as the respiratory center and the heart can withstand the strain involved until the third line of defense is established, the patient will make good. This third line of defense is the shut ting off of the damaged area of lung. As I described in my last lecture, the alveoli most affected become consolidated and the blood practically ceases to flow through them. Others less affected clear up and the patient carries on with less available lung substance until the oedema is absorbed and the lung becomes practically nor mal, as it does in the majority of gassed cases which recover, though some may have scar tissue and emphysematous areas. We can now formulate a rational line of treatment for cases of asphyxiant gas poisoning, and modify it according to the need of individuals. (1) The first point in treatment should be to diminish the patient's need of oxygen by every possible means—by keeping him at rest and by warmth. To keep him at rest necessitates a special organization for evacuation of gas casualties when these occur in numbers, and I shall hope to refer to this again in my last lecture. Warmth can be given by means of hot water bottles or by preparing a stretcher with folded blankets and applying warmth by means of a Primus stove as was done in cases of surgical shock. If circumstances permit, patients should not be evacuated to the lines of communication until all serious symptoms have disappeared. No. 3. 413 GALWEY GAS WARFARE. (2) The next and most important point is the administration of oxygen. But on service, oxygen is difficult to obtain in large quan tities and also difficult to transport. What then should be the indi cations for administration of oxygen? If a patient has no cyanosis —whether of the plum-colored or pallid variety—oxygen is not necessary. If he has cyanosis, oxygen is necessary and should be given at the earliest possible moment to prevent the vicious circle initiated by even slight anoxaemia. This is most easily and economically given by the portable appa ratus devised by Professor Haldane, and with comparatively little trouble an installation can be arranged so that two or three orderlies can attend to a number of patients. The administration should be begun early and should be perse vered with, even though apparently there is little improvement in the patient. Remember that lack of oxygen may have already done damage to important structures and organs and that it will take the patient time to recover from this even though oxygen administration may prevent further damage. Usually a delivery rate of 2 to 3 liters per minute is a sufficient dose, the mask being withdrawn for five minutes every half hour. In very bad cases up to 5 liters per minute have been given with ex cellent results. Once the patient regains his color and his pulse improves and the improvement is maintained, oxygen may be stoped; but any return of the symptom indicates resumption of the administration. Oxygen is itself irritating to the lungs in large quantities and should not therefore be pushed further than necessary. Before leaving this treatment it is only fair to say that in a series of experiments carried out on dogs exposed to standard doses of gas by Underhill, the American observer, he found that administra tion of oxygen neither delayed the time of death nor increased the percentage of recoveries. Clinical experience in France, however, proved beyond doubt the value of this treatment. Again and again apparently hopeless cases recovered when oxygen was given efficiently and over long periods. Venesection. —Clinical experience in France was in favor of bleed ing in irritant-gas poisoning, but not as a routine treatment in all cases. It is certainly justifiable in cases with venous congestion to relieve an overburdened right heart. The quantity removed should amount to 20 ounces (550 cubic centimeters) and the bleeding should be done slowly —about 20 minutes for the quantity mentioned. In the pallid cases the treatment was not considered justifiable. On the other hand, the work of Underhill in the treatment of gassed dogs brings forward very strong evidence in favor of early bleeding and still stronger evidence in favor of bleeding and injection of 414 Vol. XVII. GALWEY GAS WARFARE. saline. In phosgene poisoning he found that in many cases early bleeding was sufficient to save the animal, whereas in chlorine bleed ing plus infusion was indicated. The reason he gives for this difference is that in phosgene poisoning there is in the early stages a preliminary dilution of the blood—the fluid being probably with drawn from the tissues —before the stage of blood concentration and stagnation sets in. Early bleeding to 0.5 per cent of the body weight of the animal relieved the distension of the heart, and in many cases this treatment sufficed. In some cases, however, the condition of dilution recurred, and was always accompanied by a rise of tem perature. When this happened he bled the animal again, and even repeated the procedure a third time until blood to 1.5 per cent of the body weight had been withdrawn. If after this the stage of concentration occurred he infused or injected intraperitoneally nor mal saline. In chlorine poisoning he did not find this stage of early dilution occur. The blood immediately began to concentrate, and for this reason he bled the animal and infused a quantity of normal saline equal to the amount of blood withdrawn. There are obvious objections to adopting this as a routine treat ment in the case of human patients. To begin with, the personnel required would be very large when gas cases were numerous. Nor does experience in France go to show that bleeding was necessary in all cases. One thing is, however, fairly certain, i. e., that in the early stages of blood concentration and stagnation bleeding does no harm, and that bleeding and infusion with saline will probably do good by increasing the volume of circulating blood. The experimental evidence goes to show that normal saline is the best diluting fluid to employ. Drugs. —The inhalation of ammonia vapor often gives relief in the early stages of chlorine poisoning. It probably acts more as a stimulent than in any other way. It should not be given in too strong a concentration, and if it increases the cough or dyspnoea it should be withdrawn. Atropine was tried as a means of relieving the bronchial spasm which sometimes occurs, but little benefit appears to have been gained by its use. Cardiac stimulants.—Brandy has proved very effective. Pituitrin 0.5 cubic centimeter hypodermically, at intervals of not less than three hours; hypodermic injections of camphor, or caffeine have been well spoken of. Neither strychnine nor digitalis proved of much value. Morphia should only be given in cases of extreme restlessness, and then the dose should be small. No. 3. 415 GALWEY-— OAS WARFARE. Expectorants should be given with caution. Their use in the first two days is contraindicated for fear of increasing the damage to the lung by coughing. , Aspirin and phenacetin should not be used to relieve the head ache which occurs. Such methods as emetics, tickling the throat, and posture to aid the drainage of fluids from the lungs have been used with success. Food should only be given in fluid form and sparingly in the acute stage, and the diet should be light till convalescence is well established. There seems to be little to be gained by an}' form of treatment specially designated to correct the accumulation of carbonic acio or other acids in the blood. TREATMENT OF THE LATE EFFECTS OF GAS POISONING. Apart from the treatment of the neurasthenic symptoms and func tional disturbances which appear in certain patients during conva lescence, and which I shall refer to when dealing with the treatment of mustard-gas poisoning, there is evidence to show that the cases of cardiac disturbance and spasmodic dyspnoea are due to chronic lack of oxygen. Observations on these patients have shown that their breathing is much shallower than that of normal persons, and shallow breathing is a cause as it is also a result of lack of oxygen. It may be that during the acute stage the respiratory center has been so damaged that the reflex controlling inspiration and expiration becomes abnormally sensitive and fires off before the normal dis tension or collapse of the lung has been reached. The lack of oxygen is not due to the anatomical condition of the lung itself, for in the great majority of cases, if the patient survives, the lung quickly returns to normal and very little permanent damage remains. The shallow breathing is accentuated by the lying posture, and this explains the dyspnceic attacks at night. The condition is markedly relieved and in many cases was cured by administration of oxygen either by means of a Haldane apparatus or by making the patient sleep in a special chamber in which the atmosphere was enriched by oxygen. Moreover, experiments on an ergometer showed that patients suffering from the effort syndrome could perform more work without dyspnrea if given inhalations of 02. VESICANTS.

Mackintosh in the Quarterly Journal of Medi cine, volume xiii, No. 50, January, 1920. At the time of exposure to this gas. nothing is noticed save the faint smell usually likened to garlic or mustard. After a lapse of two or three hours symptoms begin to make their appearance and the intensity and duration depend upon the concen tration of the gas. The eyes usually are the first to show signs of the mischief —an acute conjunctivitis, which develops rapidly. There is extreme lach- rymation accompanied by headache. Blepharospasm is marked. From the second day the discharge is mucopurulent, and the injury may go on to corneal ulceration, but this complication is not common. Later, photophobia of functional origin develops in a considerable number of cases. Coinciding with the development of eye symptoms there is nasal catarrh, and sneezing is frequent. Nausea, retching, and vomiting, with epigastric pain, are common at the same period. During the next few hours other signs and symptoms make their appearance. The throat feels dry and burning, the voice becomes hoarse and a brassy cough develops. A red erythema appears on the skin of the face and neck, and other parts of the body (particularly where the skin is moist) are similarly affected. Small blisters and blebs appear later in these areas. In the early stages the condition resembles the rash of scarlet fever. During the second 24 hours the vesicles develop into large blisters, while the scrotum and penis, if affected, become cedematous and pain ful. Eespiratory signs now appear with the onset of bronchitis, and in the mucopurulent sputum large sloughs from the inflamed tracheal lining may be found. Secondary infections of the respiratory tract, varying from puru lent bronchitis through broncho-pneumonia to bronchiectasis and even gangrene of the lungs, supervene and cause death. The temperature, pulse, and respiration rates vary in accordance with the character and severity of these affections. Post-mortem. —The most important changes are found in the respiratory tract. Throughout its entire length it is acutely inflamed and covered with a yellowish-white false membrane, representing the disintegrated and desquamated epithelial lining mixed with a fibrin ous exudate. On removal of this membrane a red granulating sur face is exposed, sometimes pitted by small ulcers. The lumen of the trachea is filled with a thin pus, and pus can be squeezed from the bronchioles when the lung is cut. No. 3. 417 GALWEY GAS WARFARE. The lungs are voluminous, but they do not exhibit the massive oedema characteristic of the asphyxiant gas cases. In early deaths small hemorrhages may be found and scattered areas of emphysematous and collapsed alveol. As a secondary lung infection extends, the appearance are those of typical broncho-pneumonia, going on in some cases to small abscess formation. The alimentary tract. —Although vomiting and retching are early signs of mustard-gas poisoning they do not as a rule persist after the first 24 hours. According to English observations a true gastritis is rare, though it does occur. French writers, on the other hand, state that in their view the digestive system frequently participates in the syndrome; gastric pain and discomfort and diarrhea, often bloody, help to weaken the patient, and when there is a general affection of the skin produced by mustard gas, and not a purely local one, the digestive apparatus is always involved. In their view the lesions in the di gestive tube are sufficiently marked to account for the symptoms. The gastric mucosa has lost its sheen and is dark in color ; ecchymotic areas and sometimes true ulcers are found. German observations do not support this view. In this connec tion one may say that apart from the mustard gas, which may be actually swallowed with saliva, there is experimental evidence to show that dichlorethyl sulphide when injected subcutaneously ap pears to be obsorbed and excreted by the mucosa. The Americans claim to have obtained systemic effects which are quite characteristic and unmistakable on the heart, alimentary tract, and central nervous system. They state that these effects are pro duced by hydrolysis —the mustard gas being broken up into hydro chloric acid and a body which can be recognized by converting it back again into mustard. And that the products of hydrolysis are found in the urine. The time taken for a solution of mustard gas to hydrolyze in vitro corresponds with the time taken for symptoms to appear after exposure to the vapor. The experiments are not yet conclusive, but the Americans hold that the evidence already to hand strongly supports their view. Urinary system. —Albuminuria is present in serious cases as an early symptom, and if persistent is a sign of grave import. Acute hsemorrhagic nephritis has been described. Circulatory system. —The heart is unaffected at first, except by changes associated with the pulmonary complications. Later, in convalescence, symptoms of D. A. H. and the effort syndrome are observed in a considerable number of cases. Observers are agreed 418 Vol. XVII. GALWEY GAS WARFARE. that these symptoms are of nervous origin, and depend largely on the methods of treatment adopted in the early stages. Blood changes. —The leucocyte count is of importance in mustard- gas poisoning. In the early stages, from the first to third day, occasionally later, there is a great leucocytosis which may rise as high as 35,000. The increase is due to the polymorpho-neutrophiles, which number about 98 per cent of the total. Even when the total count is not raised, there is a relative in crease in these cells. The lymphocytes are reduced in numbers; eosinophile and baso- phile cells practically disappear. The large mononuclears remain either normal or are reduced. In serious cases a fall in the leucocyte count beginning about the third or fourth day is a sign of bad omen, unless there is marked improvement in the patient's condition; and a leucopsenia occurs just before death. There is no change of note in the red blood corpuscles. But the coagulation time of the blood is said to be markedly diminished. TREATMENT OF CASUALTIES FROM MUSTARD GAS. Immediately on arrival at the gas casualty center, or. if practical, at the aid post or advanced dressing station, steps should be taken to get rid of all traces of mustard gas from the patient, his clothing, and equipment. I have alread\? dealt with the methods of disinfection of clothing, and need only add that when clothing is taken from the patient it should at once be disposed of in a safe place where it can not injure others by continuing to give off gas. The patient should then be washed from head to foot with warm soapy water to which bicarbonate of soda 20 parts per 1,000, or lime water 1 part per 1,000, has been added. Particular attention should be paid to his hands, which may be infected, lest by scratching he convey the poison to other parts of the skin. He is then dried and put to bed in clean clothes. Care should also be taken to prevent injury to the personnel attend ing to the patient. The conjunctivae should then be washed well with a 2 per cent solution of bicarbonate of soda or warm boric lotion, and liquid paraffin instilled. This treatment should be frequently repeated, particular attention being paid to the cornel's and the eyelids being everted, if possible. If liquid paraffin is not available, castor oil may be used, but is more irritating. If the cornea is affected. 1 per cent sterile atropine ointment should be used instead of paraffin, and repeated sufficiently often to keep the No. 3. 419 GALWEY — GAS WARFARE. pupils dilated. Cocaine should not be employed. Washing with potassium permanganate 1 in 4,000, or the application of an oint ment, containing potassium permanganate or methylene blue are recommended. If the discharge becomes mucopurulent, 2 per cent solution of argyrol or protargol should be applied once a day. The eyes should never be bandaged. Dark glasses or shades may be given for the first two or three days, but should be dispensed with as early as possible. The photophobia which follows the affection of the eyes is nearly always functional, the patients are in a very sug gestible condition, and unless a firm attitude is adopted and an atmos phere of cure established at once by impressing on them that the injury will not be permanent a neurasthenic condition develops which is very intractable and prolongs convalescence indefinitely. Plung ing the head into cold water with the eyes open often cures these functional symptoms. The nose and naso-pharynx should be washed out with warm alka line solution three times a day. This should be poured in, not snuffed up. Relief to the condition of the larynx may be obtained by inhala tion of steam from boiling water to which an ounce of tincture ben zoin co. and 10 grains of menthol have been added. The French recommend a laryngeal injection of gonienol oil 1 to 2 cubic centi meters daily. The. laryngitis usually clears up in a fortnight, but a functional aphonia may develop which is best treated by strict methods. Tracheitis may be eased and the risk of secondary infection less ened by the use of a perforated metal mask moistened with drops of an antiseptic solution, such as : Menthol grains— 20 Tinet. iodi mininis__ 30 Oil of eucalyptus do 30 Creosote dram__ 1 Chloretone do 1 Alcohol to ounce. _ 1 When secondary infections such as broncho-pneumonia occur the appropriate treatment should be given. Venesection or oxygen may he used if cyanosis develops, but these measures are never called for in the early stages of mustard-gas poisoning. The vomiting and other symptoms arising from infection of the alimentary tract may be relieved by warm drafts of a solution of bicarbonate of soda. The diet in the early stages should be mild and light. Indeed, inflammation of the posterior pharyngeal wall may make swallow ing a matter of difficulty. 420 Vol. XVII. GALWEY GAS WARFARE. Skin lesions. —After the initial washing with soapy water and bicarbonate solution, a dusting powder of boracic acid, chalk, starch, and zinc oxide or calamine lotion should be applied to relieve irrita tion. Fatty ointments give no protection against the poison. Small burns heal well under Lassar's paste with 2 per cent salicylic acid. Washing with 4 per cent solution of potassium permanganate and applications of ambrine have also been recommended, but before the latter is applied care should be taken to render the skin aseptic. Large excoriations or areas with pyogenic infections should be treateJ by soaking with boracic lotion for a short perio,d and then applying zinc ointment with ammoniated mercury. Functional symptoms. —Mustard gas cases are very liable to de velop during convalescence hysterical symptoms, such as vomiting, photophobia, aphonia, or D. A. H., and it is of the greatest impor tance to remember this and frame the early treatment so that what the French describe as " benign contagion "—an atmosphere of cure — is established at once. Unless this is done, not only may the patient remain in hospital but he may become a confirmed neurasthenic. In France it was found that by adopting a strict and hopeful atti tude a very large majority of the cases of mustard gas poisoning were fit for discharge from hospital within four to six weeks. In England, on the other hand, many cases were still unfit at the end of twice or three times that period. Allowing for the fact that the most serious cases went to England, this period is too long, and inves tigation proved that a great number were suffering from neuroses. How far these neuroses are the result of gas or of general war strain is a matter of doubt. In any case, the neurotic element should never be forgotten in gas poisoning. Being a new weapon it was naturally very terrifying, and the fact that unless in large concentrations the smell was almost impercep tible, kept men in a state of expectant strain. Many men thought they were gassed when they were not, and toward the end of the war it became necessary to send men to the gas centers diagnosed N. Y. D. gas or query gas, just as they were sent to the neurological centers diagnosed N. Y. D. nervous. In such cases it only required a little injudicious sympathy to bring about a nervous breakdown ■ with all kinds of symptoms which were merely manifestations of a conversion hysteria. I have mentioned D. A. H. as one of the neurasthenic manifesta tions in the late stages of mustard-gas poisoning. As far as can be judged this syndrome did not arise from the same cause as the D. A. H. of eases of irritant gas poisoning. In the latter it appears to have been consequent on the lack of oxygen in the early stages which having upset the nervous reflexes gave rise to chronic No. 3. 421 GALWEY —GAS WARFARE. shallow breathing. ' In the cases of mustard gas, on the other hand, it appears to be a symptom of the general neurasthenic condition of the patient. It is well then whilst adopting energetic treatment of actual lesions to restrain oversympathy with the patient and to impress upon him that he will in all probability shortly be quite fit to return to duty. C hlorarsines. —When the blue cross shell was first introduced the effects were limited to irritation of the eyes, nose, and throat and a burning pain in the chest. These symptoms were transitory and did not produce serious casualties. Later, however, definite symptoms of poisoning by these compounds were observed and were probably due to the introduction of ethyldi- chlorarsine or to drinking of water contaminated by the blue cross shells. These symptoms were as follows : Burning pain in the nose, mouth, and throat; smarting of the face; aching pain in the eyes with in tense lachrymation and mild conjunctivitis; frontal headache and copious watery discharge from the nose; burning pain in the chest: salivation; pain in the stomach, nausea and vomiting. In some cases sensations of pins and needles were experienced, or temporary numbness and loss of power in the limbs without the sen sation of pins and needles giving place to aching pain, but with no tenderness of the main nerve trunks. A curious symptom is the extreme degree of mental misery to which exposure to this compound gives rise. These symptoms are in the main transitory and in many cases were not sufficient to cause evacuation of the patient; or, at the worst, cleared up in a few days, except in those patients who developed neu rasthenic symptoms which were rather attributable to general war strain and weariness than to the action of the gas. In a certain proportion of cases alterations of sensation and of reflexes appear in the late stages, but authorities are agreed that the lesions can not be attributed to a definite arsenical neuritis, and that they are probably functional in origin. Such is the clinical picture of the casualties inflicted by the enemy use of the arsine compounds; but there is definite experimental evi dence to show that these compounds can cause much more serious symptoms, and may be lethal. Pathological examinations of animals which succumbed to the ef fects of these compounds show that lesions occur in the respiratory tract which are sufficient to cause death. Pulmonary cedema is com mon and frequently severe, but the chief feature is serious damage in the upper air passages. Frequent exposure apparently increases susceptibility to their effects. 646—22 1 Usher Parsons, Surgeon, United States Navy. V HISTORICAL. USHER PARSONS (1788-1868), SURGEON, UNITED STATES NAVY.' By F. L. Pleadwell,, Captain, Medical Corps, United States Navy. Usher Parsons was born in the town of Alfred, York County, Me., when Maine was still a district of the State of Massachusetts, so that both States may rightfully count him among their distinguished sons. The date of his birth was August 18, 1788. He was the young est of the nine children of William and Abigail Frost (Blunt) Par sons. William Parsons was descended from Joseph Parsons, who came to this country from England in 1635, settling first at Spring field, later at Northampton, Mass. His oldest son, Joseph, became a prominent citizen and trader in Northampton and died there in 1729. Joseph's oldest son, also named Joseph, graduated at Har vard College in 1697, and was a pupil of the Rev. Increase Mather. He became a clergyman at Lebanon, Conn., afterwards at Salisbury, Mass., where he died in 1740. His oldest son, in whom was still per petuated the name of Joseph, was a clergyman at Bradford, Mass., from 1726 to his death in 1765. This Joseph, who married Frances, daughter of John Usher, lieutenant governor of New Hampshire, was Usher Parsons's grandfather. Joseph and Frances Parsons had six sons, and of these three graduated at Harvard and were, re spectively, clergyman, physician, and lawyer. The remaining three children became mechanics or traders. It is noteworthy that of the two groups of children those who went to college survived only to an average age of 36 years, while those who remained at home and followed the trades reached an average age of 76 years. The fifth son, William, was Usher's father. He was born in Bradford, Mass., in 1743, and followed, by turns, the calling of trader, farmer, manu facturer of potash, lumber merchant ; he was also a town officer. William Parsons left Bradford and settled first in South Berwick, Me., then in Alfred, where he died in 1826. He married Abigail Frost Blunt, daughter of Rev. John Blunt, of Newcastle, N. H., whose wife was a daughter of Hon. John Frost. The mother of John Frost was a sister of the celebrated Sir William Pepperrell, who captured Louisburg in 1745. • 1 For much of the material appearing in this article the writer is Indebted to the article on Usher Parsons in Kelly and Barrage's " American Medical Biographies " and to a •■Memoir of Usher Parsons, M. D.," by his son, Charles W. Parsons. 423 424 Vol. XVII. PLEADWELL USHER PARSONS. The family connections mentioned in this review of Usher Par- sons's ancestry will explain not only the origin of his Christian name, but also his interest in writing in 1855 a life of Sir William Pepper- rell, who possessed the distinction of being the only native of New- England who was created a baronet during its connection with the mother country.2 Usher Parsons's boyhood was spent in Alfred, where he attended the village school in winter and worked on his father's farm in summer. He was 11 years of age when General Washington died and often recalled wearing crape and taking part in a mourning procession of school children on the occasion of this sad event. When 12 years of age he was sent to school at the Berwick Academy, but only remained there a year, a period far too limited for him to ac quire more than the bare rudiments of a preliminary education. After leaving school he worked as a clerk in several retail stores in Portland and AVells (now Kennebunk). Me. His service in the latter town terminated on March 29, 1807. As an indication of its very satisfactory character the following certificate of his employer is quoted : This may certify that I. the subscriber, of Wells, have employed Usher Parsons as a clerk to assist me in my store for upwards of eight months: and have found him to he a capable Lad, posses-st of steady habits, and well calcu lated for book-keeping. Wells. August 16th. 1800. Daniel Little.' On May 6, 1807, when not quite 19 years of age, Usher Parsons began his life work by entering the office of Dr. Abiel Hall, of Alfred, as a student in medicine. His industry as a clerk had enabled him to accumulate a little money, and these savings were drawn Upon now for board, lodging, books, and later for a course of anatomical lectures which he attended at Fryeburg, Me. These lectures were delivered by the well-known Dr. Alexander Ramsay, an eccentric but gifted Scotchman, who had come to this country from Edinburgh in 1802 to offer his services at the time of the yellow-fever epidemic in New York. Usher Parsons's lifelong inter est in anatomy had its origin in the teachings of Doctor Ramsay, who was himself an enthusiast in this branch of medical science. During his apprenticeship with Doctor Hall he studied anatomy, saw a little of the practice of medicine, read Dr. William Cullen's First Lines of the Practice of Physic (1776-1794), and studied the works of Erasmus Darwin4 and the celebrated Dr. John Brown."' •Life of Sir William Pepperrell, Bart., Cambridge, Mass., 1865.

PLEADWELL— X'SHER PARSONS. 425 His medical studies were often interrupted by visits home, where he worked on his father's farm, and by periods of teaching school in Alfred and neighboring towns, in order to add something to his slender funds. While still at Kennebunk, Parsons printed his first literary production, in the shape of some verses entitled "A Petti fogger's Soliloquy," which appeared in the Freeman's Friend, a newspaper published in Saco, Me. Of the incidents of his daily life at this period, and of his efforts at self-improvement, both in general education and in medical work, and of the difficulties met with and overcome in prosecuting his studies, we may learn most satisfactorily from the following extract, which is taken from an account which he wrote himself in later years : Rein? disappointed of a remittance from my father of some money to enable me to attend a second course of lectures in Portland, by Doctor Kaluga;, I walked about 15 miles in the night, nearly to Saco, slept a few hours on some hay in a barn, and I reached Kennebunk the following noon, and Alfred in the evening. During my moonlight walk, I meditated on the past and the future c-nnrse of my life. I thought of the misspent time of my past years, of my low alms in the medical profession, until within the last few weeks, and asked if it would be possible, at this my 21st year, to begin a new course, that should redeem the time, and elevate me to a respectable rank in the medical profes sion. I was now wanting in preparatory education, unable to parse the most simple sentence in Latin, and hardly able to write a common letter in Knglish grammatically. I had no means of educating myself but by school keeping. How many years am I willing, I asked, to devote to this and to hard study for tie attainment of a rank in the profession that, with my present ambitious views, I shall be satisfied with? I concluded that 10 years would be required, and determined that all my energies should be employed for that length of time. lot who. like Colombo, Borelll, and other ingrutes of medicine, turned against his quiet teacher with the pleblan's usual tactics of reviling his Intellectual betters In order to Halt himself. Yet the Brunonlan theory, as It was called, actually held the attention of Europe for a quarter century, and as late as 1802 a rlxa, or students' brawl, between Brunonlnns and non-Brunonlans at the University of GBttlngen lasted two whole days and had finally to be put down by a troop of Hanoverian horse. As far as It went, the theory *as absolutely consistent and complete In all Its parts. Brown regarded living tissues as ?icitable," in lieu of the Hallerian "Irritability." and life Itself as nonexistent, except as a resuttiint of the action of external stimuli upon an organized body. Diseases are Hen " sthenic " or " asthenic," according as the vital condition of " excitement " Is Increased or diminished. The essentials of diagnosis are simply whether a disease Is institutional or local, sthenic or asthenic, and In what degree, and the treatment con- •ists in either stimulating or depressing the given condition. To this end, opium and, of course, alcohol were Brown's favorite agents. Hippocrates said that no knowledge of 'he brain can tell us how wine will act upon any particular Individual, and Brown pro- 'wded to apply this experimental Idea In propria persona to elucidate his theory, using successive doses of five glasses at a time. Abuse of opium and alcohol eventually killed him. His method gained^ little support in France and England, but Rush took it up In America, Rasorl, Moscati, Brera, and others In Italy, and In Germany, after Chrlstopb 'ilrtanner's plagiarisms of 1790 had been exposed and the " Elementa medlcinne," trans lated by M. A. Welkard, Brown came Into his own. The book hypnotized even Peter Frank at»l RSschlaub. and was greeted by a flood of pamphlets and salvos of praise. Although Ms errors were pointed out by Humboldt and Hufeland, Brown had the unique distinction "f polarizing the German profession.

My resolution was now fixed and my plans matured this night, and in the main were not deviated from during that length of time. I determined to obtain the degree of A. M. and M. D., and to become a teacher of anatomy. On arriv ing at Alfred, I packed up my Latin books, and went to Sanford, 4 miles off. and placed myself in the family of Parson Sweat. I began with the Latin grammar, and by the last of November had gone over it several times and read two books in Virgil, and was able to read the Greek Testament a little, l then taught school two months in Elliot ; then returned to Parson Sweat's a few months; then went in May to keep school three months half a mile from Ber wick Academy ; then attended the academy one quarter, and read two or three of the Evangelists (in Greek), and four orations against Catiline; then kept school at Alfred three months, and during evenings read Virgil nearly through, finished the Evangelists and the book of Romans. I now felt that to go through college in this tedious way would be likely to consume tlie 10 years. I there fore concluded to return to medicine; to read a few months with Doctor Hall, at Alfred, and then study with some very eminent person six months, which would complete my three years, to attend a course of lectures, und then com mence practice, or be ready to commence whenever a vacancy offered, and en deavor to go through the college studies whilst trying to get into practice. Accordingly I went to Doctor Kittredge, of Andover, but found him from home. I then went to Boston and entered the office of Doctor John Warren, for six months. It was with much difficulty that I got through with the expense of lectures and board, although assisted to $50 by my father. Following the plan mentioned above, Usher Parsons went t« Boston in July, 1811, and succeeded in establishing himself under the preceptorship of the eminent surgeon, Dr. John Warren, brother of Doctor Joseph Warren, who fell at Bunker Hill. While in Bos ton he boarded at the Market Tavern in company with his brother- in-law, Gen. Samuel Leighton, then representative to the General Court from Elliot. In February, 1812, he underwent a successful examination before the censors of the Massachusetts Medical Society, and was duly licensed as a " practitioner of medicine." 6 ■ISeal] Commonwealth of Massachusetts.

In half an hour we came within musket shot of the enemy's new ship Detroit. At this time they opened a most destructive fire on the Lairrcncc from their whole squadron. At half past one, so entirely disabled we could work the brig no longer. At two P. M., most of the guns were dismounted, breechings gone, or carriages knocked to pieces. At half past two, when not another gun could be worked or fired from the Lawrence, Captain Perry hauled down the fighting flag, which bore this motto, Don't give vp the ship, repaired on board the Niagara, and there raised it again. In ten minutes after we struck to the enemy Captain Perry made all sail with the Niagara, which hitherto had kept out of the action, and in fifteen minutes passed in among the British squadron, having the Detroit, Queen Charlotte, and Lady Prevoxt on the starboard side.'and the Hunter on the larboard side, and silenced them all, and ten minutes before three they hauled down their colors. Two small vessels attempted to escape, but be ing overhauled struck a few minutes after three. Killed on board the Lawrence (one lieutenant, eighteen midshipmen, and three others; sixty-three wounded). Slept but little, and dressed about one-third, and secured with tourniquets such as bled copiously. During the action I cut off six legs in the cockpit, which were nearly divided by cannon balls. Still further details of the action appear in the following extract from a letter to his father : Near the Hkad of Lake Erie, On Boabd the tJ. S. Sr.oop Lawrence, September 22, 1813. Before the arrival of this an account of our victorious engagement with the British squadron on this Lake will reach you. I can only add a few particulars. Most of the action was supported by this vessel, as you will suppose when in formed that out of one hundred and fifty men (our ship's crew), thirty-one of whom were sick previous to the action, we had rising eighty killed and wounded, among whom were nearly all our officers save the intrepid Commodore. On board all the others were about thirty killed and wounded. This vessel was engaged with the enemy's two ships on one side and a brig astern raking us for two hours, all within musket-shot, during which we rendered the ships unman- aseable, and when this vessel could not discharge another gun, the Commander repaired on board the Niagara; and within fifteen minutes after he arrived within close action with them, the enemy's three vessels struck. Unfortunately for the wounded, the two surgeons had been confined for several days with fever, and could render them but little assistance. It has however operated in my favor, as I have had all Ihe amputations to perform; and it affords me the greatest pleasure to reflect that in no case have I failed of the best success. This has inclined the Commodore's opinion so much In niy favor that I have no doubt he will render me assistance towards obtaining a better situation. He is the first warm friend I have met with in the service capable of assisting me. I am now on my way in the Lawrence for Erie, hav ing all the sick and wounded of the squadron on board, and shall continue in the hospital with them till they in a measure recover, and will then direct my course toward -Cape Home. General Harrison w-as' on hoard the Laiortwe this morning, and his army was on an island within half a mile of the vessel. It is supposed to consist of at 'east eight hundred regulars, militia and Indians. To-morrow they cross to Maiden, a distance of about eighteen miles. Since the capture of the British 432 Vol. XVII. PLEADWELL USHER PARSONS squadron, the Indians have evacuated Detroit, after burning the place, and (as is reported) massacring the inhabitants. The enemy's squadron mounted more guns than ours, and carried more men by at least one-fourth. I had some narrow escapes for my life during the action. Five cannon balls passed through the room in which I was attending to the wounded. Two of the men I had dressed and laid aside in the commencement of the action were killed, before it closed, by other shots. I have had very poor health all the cruise, am reduced to a skeleton, but am recovering. Never will I cruise again on this lake or any other. The action was fought within about ten miles of Maiden. The enemy came out over night for the purpose of attacking us, and in the morning were within about fourteen miles of us, the wind in their favor. We made sail to meet them, and the wind changed in our favor, which gave us an advantage over them. They had more killed and wounded than we. It was a unique and almost unparalleled experience for a surgeon to have such a burden of casualties thrust upon him in so short a period of action, and the results speak well for Doctor Parsons's skill. Twenty-two officers and men were killed on the Lawrence, and several others with shattered limbs died shortly afterward. The wounded on the Lawrence numbered 61 ; in the whole squadron 96. Except for a consultation with two British surgeons on September 13, and assistance rendered by a surgeon sent him on the 14th from General Harrison's army. Doctor Parsons handled all the wounded himself. In referring to his work. Commodore Perry, in a letter to the Secretary of the Navy stated : Of Dr. Usher Parsons, surgeon's mate, I cannot say too much. In consequence of the disability of both the other surgeons. Prs. Horscly and Barton, the whole duty of operating, dressing and attending nearly an hundred wounded, and as many sick, devolved entirely on him: and it must bp pleasing to you, sir, to reflect that, of the whole number wounded, only three died. I can only say that, in the event of ray having another commnnd, I should consider myself particularly fortunate in having him with me as a surgeon. Doctor Parsons attributed his success in the treatment of the wounded to several factors. From the 12th to the 2'2d of September they were lodged in the open air on the upper deck of the Lawrence, sheltered by an awning. In addition they had a plentiful supply of cordials, fresh vegetables, and provisions, and finally they were buoyed up by the cheering influence of victory. On September 23 the Lawrence reached Erie, and the sick, wounded, and prisoners were landed and placed in the hospital there. For nine months Doctor Parsons continued in charge of this hospital at Erie, during which time he made many friends and formed many endearing associations there, which were a great source of pleasure to him in later years. Congress voted medals commemorative of the Lake Erie victory to all participants and Doctor Parsons received one of them in common with other officers. He also received a share of prize money, which was used to pay off the balance of debt incurred in obtaining his No. 3. 433 PLEADWELL —USHER PARSONS. medical education. Not the least of the rewards which came to him as a result of his service on the Lakes was the surgical experience and Commodore Perry's friendship. During the period from January 1 to February 5, 1814, he appears to have had service with the land forces at Erie, being assigned as surgeon of the Twelfth Regiment, Pennsylvania Militia, by orders from Maj. Gen. David Mead. On April 15, 1814, Doctor Parsons received his promotion to sur geon, and on the 19th he sailed with the fleet from Erie for Detroit and Lake Huron. Troops were embarked at Detroit, and the com bined land and sea forces then proceeded through Lakes St. Clair and Huron, and attacked Fort Mackinac. The attempt to reduce the fort was unsuccessful, and several officers and men wore lost. The fleet returned, and Doctor Parsons was back at Erie on September 21. The incidents of Doctor Parsons's career from this time on are best described by quoting directly from the " Memoir of Dr. Usher Parsons " by his son. Except for a few minor changes in phraseology the text of this work has been followed strictly : Perry had returned to the seaboard, and been appointed to command the new frigate Java, building at Baltimore, and was allowed to select his own officers. He chose several of his companions in lake service, among others, Or. Parsons, who on the second of December, 1814, received orders to report to Perry at Bal timore. He was attached to the Java, under Perry, through the years 1815 and 1816. He appears to have now revisited his native village. It was at this period that he first came to Providence, traveling by stage with his comrade, Thomas Breese. They lodged at the house since known ns the " Manufacturers Hotel." He passed the year 1815 mostly with the frigate, at Baltimore, Nor folk, New York, and other ports. War witli England had ceased, and the frigate was ordered to the Mediterranean, to look after American interests, especially in connection with the Barbary States, and the threatening attitude of Algiers. He sailed from Newport as surgeon of the Java, January 22, 1816, and reached the Straits of Gibraltar, February 12. On February 7, in a severe storm, several men were thrown from the masts and yards ; some were killed, and others re quired surgical operations. In assisting to move them, Dr. Parsons was thrown between decks, breaking his right knee-pan. For this, he many years after wards received a pension. His diary during this voyage of the Java, contained an account of his daily occupations, with full description of local customs and interesting places. He visited Gibraltar, Malaga, Port Muhon on the island of Minorca, Algiers, Tunis, and the ruins of Carthage, Tripoli, Messina. Palermo, and Naples. Perry gave his officers every proper facility for excursions on shore, which were often made by several of them In company. On arriving at Algiers, April 1, they found the British fleet, under Lord Exmouth, which had gone there to secure the liberation of Christian slaves, and prevent future enslavement of captured citizens. The barbarous customs of piracy and the reduction of captives to servitude, and of demanding tribute from commercial nations, were beginning to call on that State the vengeance of the great Christian powers. In 1815, Decatur had secured by force of arms a treaty which relinquished claims to tribute from the United States, and released all American captives. Lord Exmouth now visited Algiers for a similar purpose. He obtained the release by a large ransom, of several hundred Christian slaves 434 Vol. XVII. PLEADWELL USHER PARSONS. mostly belonging to nations of Southern Europe. Dr. Parsons writes, April 7 : " The British fleet departed for Tunis with Christian prisoners. They paid from five hundred to one thousand dollars per head for them, except a very few be longing to the British, which were not ransomed. Misunderstanding arose between the Dey and Commodore Perry, and a fight was expected. Dr. Parsons writes. April 8 : " Volunteered my services to go in Captain Perry's boat, and prepared both for fighting or doctoring. " In May, he set out from Messina to visit Mount Etna. The excursion oc cupied four days. He was aceompained by Dr. Hoffman, of the United States Navy. His diary describes the villages and ancient ruins that they passed, — the three regions, torrid, temperate and frigid. — the exhausting ascent of the great cone, and the grand view from its summit, the sea, the flaming islands of Imparl, the varied landscape of Sicily, and the slopes of the mountain itself, its successive zones, its many villages, and its black rivers of solidified lava. From the village of Nieolist, which is half-way up the mountain, he was ac eompained by a local magistrate, who had never before visited the crater; and who, reading in an old French Gazeteer that Lima was in South American inquired whether the United States were near that. While at Naples, be examined repeatedly the remains of Pompeii and Her- culaneum. His journal of this voyage ends abruptly, at Naples. July 21. The Java revisited several ports on the Mediterranean, Tripoli. Algiers, Malaga and Gibraltar, and sailed in January, 1817, for the United States, bearing a new treaty with Algiers. The crew suffered with the small pox on the homeward voyage. On the occurrence of the first case, the men were mustered, and it was found that eighteen of them had never had either small pox or kine po«. They were vaccinated, but with matter brought from the United States a year previously, and the vaccination failed. Dr. Parsons thereupon inoculated them with small pox virus, and all had the disease mildly. Some continued sick when the Java arrived in Newport, and the town authorities gave permission to " land a number of persons from on board the said ship, with the small pox, at Coaster's Harbor island. " A more detailed report of the circumstances attending this epi demic was made by both Commodore Perry and Dr. Parsons, as will appear from the following letters : U. S. Ship Java, Newport, March S, 1817. Sra : The Java having arrived in the United States with several cases of the small pox on board ; it becomes a duty which I owe to myself to account to you . for a circumstance, which may appear to shew a want of that attention in me, so essential on the part of a Commander toward the health of his crew. The Invalids of the Squadron together with a number of men whose term of service had expired were sent on board the Java a few days before ray depart ure from Port Mahon, and exchanged for an equal number of her crew. Shortly after sailing a case of the Small Pox was discovered, and an attempt was made to vaccinate those who were in danger of taking the infection; but unfortunately the matter proved bad. It therefore became necessary to in- noculate them for the Small Pox, and to my surprize, on inquiry it was found necessary to perform this operation upon eighteen of those who had lately been received on board. The same number. I regret to add, have since taken it in the natural way. four of whom have died. I had taken the precaution to have the Java's Crew vaccinated prior to my leaving the I". States. PLEAD WELL USHER PARSONS. 435 Permit me Sir, to suggest for your consideration the propriety of making it tie duty (by a special order) of the Commander and Surgeon of a public ves sel and of Surgeons attending Rendezvous, immediately on a man's being ship ped or received on board, who has not been vaccinated, to cause the same to be performed on him, and that the former be directed to report to the De partment before sailing on a Cruise, their performance of this duty; and that the Surgeons be directed to keep constantly on hand a sufficient quantity of the vaccine matter. For your further Information Sir, I have the honor to enclose a report to me from the Surgeon, Dr. Parsons. I am Sir, With great respect, Your Obt. Servt. O. H. Perry. The Honorable B. W. Crowinshikld, Secretary of the Navy. • U. S. Frigate Java, March 3, 1817. Sis: Agreeable to your request I here state the particulars of the commence- meut and consequence of the smallpox in this ship. The day following our departure from Gibraltar, and eleven days after our separation from the Squadron at Mahon, a seaman was attacked with this disease in its most malignant form. This man was among those whose term of service had expired and who were transferred to this ship to be discharged on their arrival in the U. States. On mustering the others, eighteen reported themselves to have never had either the small or kine pox. By your order they were immediately vaccinated, but with matter that I had brought from the D. States a year previous, and its age had rendered it inert. As soon as it was ascertained that the vaccination would fail, I innoculated them and by the use of medicine with strict attention to diet and regimen, they all underwent the small pox in its most benign form, none of them being confined more than two or three days. Unfortunately for others, who failed to report themselves for innoculation, eighteen men were attacked with the disease the natural way. F'our of them died, and the recovery of many of the other was long dispaired of. I am, how ever, happy to inform you, that only six now remain on the list, all of whom are convalescing. Altho' the distress and loss of lives occasioned by this disease are much to be lamented, it must be a pleasing reflection to you, Sir, that you have prevented ." its spreading among our own crew by ordering their vaccination before we left the U. States. By a similar precaution on board the other ships in the Mediterranean, the serious calamity we have witnessed might have been prevented. Besides those who died on our passage with the small pox, we have lost three with pulmonary consumption, making in all seven deaths ; an unusual loss to be seen for one ship, but considering Sir, that in addition to our own sick, we had to take home all the incurable patients of the Squadron and hospital to the number of forty or fifty, and with a long winter passage, the number of deaths will seem as moderate as could have been expected. I have the honor to be, Sir, Tour mo* ob' (Signed) Usher Parsons. Surgeon. 0. H. Perry, Esq. 436 Vol. XVII. PLEADWELL USHER PARSONS. The Java arrived at Newport on March 3, 1817. On May 13, 1817, Doctor Parsons addressed a letter to the department which reads as follows : Boston, May 13, 181"!. Sir: By the order of Commodore Bainbridge I hereby report myself to the Navy Department. If consistent with the good of the service, 1 would wish for orders to remain attached to the Java, or if this indulgence cannot be granted, I would like to be continued on this station in some other situation. My object in this is to avail myself of the advantages which the town of Boston affords for pro fessional improvement. It will appear in the following narrative, which is taken from the " Memoir," that his wish to remain in Boston was gratified, and as a result he was enabled to complete his medical education and receive his degree : In July Doctor Parsons came to Providence, bringing introductions from Commodore Perry and other naval friends, and contemplating a settlement there in civil practice. He resided there four months, boarding at the house of Major McClellan.12 In November, he went to attend lectures at the medical school in Boston; and, in March, 1818, he received the degree of doctor of medicine from Harvard University. His dissertation in graduating was on " The epidemic pneumonia of 1812-13, as it appeared about Lake Erie." In that year, he published, in the New England Journal of Medicine and Surgery, a " Surgical account of the naval battle on Lake Erie," and a report of two cases of gunshot wounds of the thorax. He joined the Massachusetts Medical Society at that time. His mother died at Alfred, on the 4th of July. In July, 1818, he sailed from Boston as surgeon of the frigate Guerriere, Capt. Thomas Macdonough, for St. Petersburg, carrying out Mr. George W. Campbell, minister to Russia. He spent about . 10 days in St. Petersburg and wrote very full accounts of remarkable objects in that city and of peculiar customs. The frigate sailed thence to the Mediterranean. He was at Copenhagen October 14: off Cape Trafalgar November 4; reached Syracuse in December and spent several weeks at and near Messina. In April, 1819, the Guer- riere left Messina for Palermo, and afterwards sailed for Naples. Detailed knowledge of this cruise is best obtained from letters to his correspondents in the United States. These show that he took an active and inquiring interest in a great variety of subjects. " MaJ. Samuel McClellan, a native of Woodstock, Conn., and a pensioner of the Revolutionary War, died in Providence, February 7, 1850, aged 90 years. Ills house was for miny years a resort of the most prominent lawyers, judges, and politicians of Rhode Island, and was a scene of much original and entertaining talk. It stood on Benefit Street, opposite the present rectory of St John's Church. PLEADWELL USHEB PAKSOXS. 437 The following letter was addressed to Dr. Jacob Bigelow,13 of Boston, then professor of materia medica in Harvard University : Palermo, May 8, 1SI9. A few days since, I was favored with an introduction to the Professor of Botany and Materia Medica, and Director of the Royal Botanical Garden of Palermo. He took nie through the college and botanical garden, and favored me with a particular description of everything pertaining to them. The col lege is a superb edifice, enclosed within the walls of the garden, and is fur nished with books, prints, herbariums, etc. in abundance. In short, everything about this, as well as the garden, bears the impress of royal munificence. On entering the library, he handed me a book and asked me if I knew the author, it was the Flora Bostoniensis (written by Dr. Bigelow). He was much grati fied with my reply, as well as with one of your papers on the comparative forwardness of the seasons, which I hail taken care to have in my pocket. He observed that he had hitherto been obliged to depend on the botanical gardens of England for all his American plants, but was now desirous of obtaining them direct from America, and asked if I would name his wishes to you. For the last six weeks our squadron has been in the harbor of Messina about one hundred miles from this. My opportunity for acquiring information of this sea has therefore been very limited. I have seen the other medical school of Sicily, at Catania, which is about as large and well conducted as the one at Palermo, there being about eighty students in each. We sail to-morrow for Naples, from which I shall visit Home and Florence, and return home through France and England. At Palermo, he saw the telescope with which the first of the plan etoids, Ceres, was discovered by Piazzi,14 on the first day of the cen tury. He remained at Naples a few weeks, and writes from there a long letter to Mr. John Pickering,15 of Salem. Mass., in regard to books he had bought for his correspondent. He says : A word respecting Pompeii, which I have visited four times, with increasing interest each time. Excavations are still carried on, and of all the disclosures of the city, about one-eighth have been made since I saw it in 1816. Then there had been three large excavations, each something more than an acre in extent, ranging in a direction obliquely across the city, and distant from each other "Jacob Bigelow (1787-1879), of Massachusetts, wan one of the greatest of American botanist*, the three volumes of his American Medical Botany (1817-1820), Illustrated with 60 plates and 6.000 colored engravings, technically devised by himself, being a work of in ternational reputation, and, in America, approached only by the writings of Barton, Rat- nnesqne. Porcher, and Asa Gray. Bigelow was visiting physician to the Massachusetts General Hospital, professor of materia medica at Harvard, and a great medical reformer. Daring the cholera epidemic of 1832 his wise sanitary rulings limited the mortality in Boston to 100, as against 3,000 in New York City. His discourse On Self-limited Diseases (1835) exerted a powerful influence upon medical practice in the United States, and, in tlie words of Doctor Holmes, did " more than any other work or essay in our own language to rescue the practice of medicine from the slavery to the drugging system which was a part of the inheritance of the profession." In 1855 Bigelow published an anonymous volume of clever poetical travesties entitled " Eolopoesis." (Garrison.) "Giuseppe Plazzl (1746-1826), an Italian astronomer.

Since that year, streets leading from one excavation to the other have been cleared out, with the houses on each side of them, so that you can now walk through the ancient city and suburbs a distance of three- quarters of a mile, on the same pavements that the inhabitants did two thou sands years since. From Naples, the cruise was continued along the Barbary coast to Gibraltar, arriving there in the middle of June. He there received permission from Commodore Charles Stewart, dated United States ship Franklin, Gibraltar, July 15, 1819, to leave the Guerriere, on account of ill health, and " return to America, or make a trial of the air of the north of Europe." He thus writes: My reasons for leaving the squadron are, that the Mediterranean climate disagrees with my health, on account of the heat and confined air of a berth- deck ; and secondly, because I am very desirous of making the tour of Europe for the purpose of professional improvement, and do not expect to meet with another opportunity so favorable as the present; lastly, I am so exceedingly tired of the monotonous scenery of a mnn-o'-war, of the perpetual jarrings that occur, and of the restrictions that nre imposed on 'officers, that a change seemed desirable for the health of the mind as well as body. He left Gibraltar July 20, and went as passenger to Leghorn. He then visited Pisa, in company with Captain Macdonough. He jour neyed thence to Lucca and Florence. He examined the medical institution in the University of Pisa, and took great delight in anatomical preparations in wax at Florence. He thence went by carriage to Rome, and there passed some days, visiting the hospitals as well as the objects of general interest.16 From Rome he em barked, September 6, in a small schooner for Leghorn, having only "the hard deck for a feather bed and without any covering; nor would any other have been of service, on account of the millions of fleas in the vessel." The voyage along the Tuscan shore was very uncomfortable. At a small unnamed port, "was called on to see an aged female afflicted with partial blindness, and another with fever. A jolly old bacchanalian is physician to about twenty soldiers who are stationed here, and to the few inhabitants. He professed great veneration for the Brunonian system of medicine, and his bloated face indicated the sincerity of his faith, though his apparel gave him the appearance of a Shakspeare's apothecary." He ar rived in Leghorn September 10. He then journeyed through Genoa, Nice, Aix, Avignon, and Lyons to Paris, arriving there September 29. He thus writes to Dr. Lyman Spalding: 17 " Little of interest appears in his notes written at Rome, except the following : " The present season a steamboat, with appropriate machinery, was ploughing up the bed of the Tiber, but I did not learn that anything was found."

Having been pretty busily engaged for two or three months !n attending hospitals and medical schools. I have thought it probable you might feel some curiosity to know how I have found them. These establishments are so nu merous and employ so many lecturers and professors that a stranger at first sizht would believe the attention of the whole city is directed toward them. I have attended the lectures of some whose names are familiar to you. particu larly Dubois. Boyer. Dupuytren, 'Kicherand, Alibert and Larrey on surgery, — Vaaquelin, Chaptal, Gay Lussac, Tnenard and Abb6 Hauy on chemistry. It is difficult to determine which surgeon to rank first, Dubois, Boyer or Dupuytren. The two first are older and consequently more experienced, but Dupuytren has h*en at the head of Hotel Dieu for several years, and during the time has per formed more operations than all the other surgeons in Paris. I am willing to acknowledge him the best operator I have yet seen, although I think very highly of the other two and of Larrey. • « * Larrey is surgeon of the hospital of the king's guards, which is but a small establishment. An opinion prejudicial to him prevails, that he is too fond of cutting —that he has fre quently amputated where it was not necessary. Medical gentlemen are per mitted to see his patients every Thursday, when he gives a particular history of every case, and performs some operations. The last time I was there, I took the liberty of introducing myself to him, which he gave me no reason to regret doing; he inquired about hospitals in the United States. I have found the people here very ignorant of the state of medical science with us, and yet very Asirous to be better informed. This circumstance has induced me to supply one of the journals with a short description of our contemplated Dispensatory. I have had the honor of becoming acquainted with Drs. Swediaur, Pinel and Cuvier. The two former are very advanced in life, and the latter is now turning politician. In another place he writes : Cnvler has exchanged natural history for politics; he has lately been erected a peer, and is a leading ultra royalist, as well as a noisy one. The liberals have enrolled his name in the list of political weathercocks, or among those who have turned at every change of government In France. Cuvier still holds a profes sorship, and continues his residence In the Garden of Plants, and gives a weekly levee in imitation of Sir Joseph Banks, to which all strangers are invited. Sir Humphrey Davy passed through here not long since, on his way to Naples, to unroll the Herculaneum manuscripts. While here he examined the chemical laboratory, with other things connected with his scientific pursuits ; hut Englishmnnlike. as the French say, he turned up his nose at everything. Every object they offered for his inspection, he considered as unimportant, or said it was borrowed from England. The following; are extracts from his notebook, entitled, " Surgical notes and observations made in different cities in Europe, particularly in Paris and London," in which he gives short accounts of hospitals and medical schools in Palermo, Messina. Xaples, Florence. Pisa, Genoa and Nice : U Charite (Paris; October 13). Went through the wards with Boyer, his "on-in-law, Itoux, and about thirty students. Saw nothing hut bad ulcers and those badly managed. The French surgeons- are neither neat, scientific nor 440 Vol. XVII. PLEADWELL USHER PARSONS. successful in their treatment of ulcers, wounds, etc. They rarely attempt to heal by the first intention ; even in amputations below the knee, the first sur geons are In the habit of stuffing the stump with lint to prevent its closing by the approximation of the skin of the sides. This practice is condemned in England and must ere long be In France. In regard to inhumanity and dis regard of life, and the practice of poulticing inflamed limbs, he also severely criticises the hospital surgeons of Paris. Larrey's manner of operating Is pleasing. He uses the knife adroitly and gracefully, and is neat in his dressings. He is humane and solacing in his be havior to the patients, differing in this respect very much from Dupuytren, whose behavior to them is savage. This is the more remarkable when it is considered that D. has always been in civil life, while L. has always been In military practice where sympathy and fine sensibilities are less known. Their stature is much alike, both being very stout and very stately in their appear ance. I,arrey is very ready and pertinent in his remarks. November 11. Went early to the hospital Salpetriere to attend the physician in his rounds. Enquired for M. Pinel, who is physician-in-chief and at the head of the institution, and sent in to him my address, with a request that I might accompany him through the hospital. He invited me into his study, and after some enquiries about American hospitals, etc. we made a tour first through three large wards full of women past sixty years of age, and who were ill. After prescribing for these, we visited the lunatic apartments in which are women in every state of mental disorder, from slight melancholy to furious mania. Those of the latter description were many of them chained, and others shut up in prisons. * * * • I found in this instance, that introducing myself to the professor had as good If not better effect than a letter would have had. He bought many medical books and instruments in Paris. Among these was Laennec's treatise on auscultation, with a stethoscope of the original pattern, now a curiosity of medical history, and certified to have been " examined and used by Laennec" Among other acquaintances formed in Paris was that of a genial and accomplished Englishman, Mr. William Clift, a pupil and con nection of the great British physiologist and surgeon, John Hunter. This acquaintance, renewed in London, ripened into a lifelong friend ship with Mr. Clift and his family, including his son-in-law. Prof. Eichard Owen, the eminent comparative anatomist. These friends corresponded with Doctor Parsons for many years, and their kind ness was continued to his relatives and to visitors whom he some times introduced to them by letter. He went from Paris to London, arriving there December 4, and remaining till Christmas. In those three weeks he became acquainted with many of the most eminent surgeons and savants of London — Sir Astley Cooper, Abernethy, and others. He attended the levee of Sir Joseph Banks. He breakfasted with Sir Astley Cooper, but found him pressed with business. He gave considerable attention to the Hunterian Museum at the college of surgeons and contemplated the formation of a museum of anatomy founded on a principle sug gested to him there, viz, that of bringing together specimens of cor responding organs and sets of organs from as many as possible of So. 3. 441 PLEADWELL USHER PARSONS. the different classes and orders of the animal kingdom. He attended two meetings of the Royal Society. Besides the usual sightseeing, he saw Kean play Hamlet at Drury Lane and heard a debate in the House of Lords, by Russell, Castlereagh, and others, on the subject of " rotten boroughs " and the expediency of admitting representa tion from large manufacturing towns in the House of Commons. The following extracts are from his diary in London : December 9. Examined the Museum of the College of Surgeons. This collec tion is calculated for physiological purjioses alone. Every organ of the animal .machine Is exhibited in as great a variety of animals as they have hitherto been able to collect.

Went to St. Bartholomew's, and heard Mr. Abernethy lecture on organic diseases of the heart to about three hundred pupils, the most interesting lecture 1 almost ever heard. His manner is peculiar, and the most engaging and amusing as well as impressive I ever heard. Dr. Mason, of New York, makes somewhat such a figure in the pulpit as Mr. Abernethy does here. He is full ot illustrative anecdotes which he tells with such a qunintness as to make one laugh. He is about fifty years old, of middle stature, head powdered, dressed in black. He sailed from Liverpool December 28, in a merchant vessel, and reached Boston early in 1820. He was ordered in May to service ut the Marine Barracks in Charlestown. While holding this ap pointment, he resided much of the time at Cambridge, enjoying opportunities of study and mingling in the learned society of that place. It was at this time, and through the influence of acquaintances pained in Cambridge, that he realized his youthful dream of being appointed teacher of anatomy, which he appears never to have given up since the year 1809. In August, 1820, he was chosen professor of anatomy and surgery in Dartmouth College. He wrote at the time: "Dr. Parsons's motive for engaging in lecturing is a desire to establish a museum of anatomy, human and comparative, on the plan of the late John Hunter's." He contributed a number of preparations, some of them in wax. which he had bought in his last visit to Europe. But he lectured there only one year.18 1SMarine Barracks, Charleston, Mass., October 9th, into.

At this time, he published at Cambridge the Sailors Physician, a medical guide for use on merchant vessels. This was extensively sold; changed its name to that of Physician for Ships, and passed through five editions, undergoing various revisions and improve ments. The four subsequent editions appeared in the years 1824. 1842, 1851, and 1867.19 In December, 1820, he left Boston to visit the medical schools of New York, Philadelphia, and Baltimore. He heard lectures from Doctors Hosack, Post, Francis, and Mott in New York, and Physick, Chapman, and others in Philadelphia. A fragment of diary still preserved shows his views of these eminent professors. He intro duced himself to them as surgeon in the Navy. His observations show that he was intent on preparing himself for anatomical teach ing. The following extract may be worth presenting: December 31. Breakfasted with Dr. Hosack.

In 1826 he published an introductory lecture on anatomy and physiology as branches of general education. The policy of President Wayland * requiring the officers of instruction to be also officers of discipline and give their whole time to collegiate duties necessarily severed his connection with the university. His special interest in anatomy, awakened in his youth by the lectures of Doctor Ramsay, continued through his whole active life. In 1831 he published at Philadelphia a volume, mostly compiled, on the Art of Making Anatomical Preparations. From the time of the death of his wife until the year 1831 he boarded at McClellan's. In 1832 he built a one-story office of three rooms on President, now Waterman Street. This he afterwards enlarged and occupied until hi9 death. Until the marriage of his son in 1853 he had no home establishment, but took his meals at hotels or boarding houses, and generally slept in his office. He liked the freedom of this way of living. During the last 15 years of his life he had a home with his son. He rose gradually to a very prominent rank in his profession. Besides his varied opportunities, which brought him to the begin ning of civil practice with more than usual experience and resources, he had many qualities of body and mind that fitted him for medical life. He was robust, with uncommon powers of endurance, and a frame strengthened by labor in early life. He was industrious, persevering, ambitious, and social ; faithful in attendance, and con siderate in his charges. His early training in naval service, and the predominance of the reflective powers, fitted him rather for the office of consulting physician, and for cases of exceptional difficulty, than for the ordinary run of daily medical practice. He had not that easy tact, that quickness of thought and command of language and features which were conspicuous in some of his contemporaries. Yet in many families of refinement and education his acquirements were appreciated and his ready sympathies and sound judgment made him a trusted adviser and friend. As consulting physican and surgeon he was very widely known in Rhode Island and in neigh boring parts of other States. For many years a large part of his practice was out of Providence. He was a fast driver; and, before the railroads were multiplied, his sulky was well known on the roads leading from Providence in all directions. He served as a surgeon of a privateer In 1782, and being captured by the British was detained a prisoner in New York, where he was put in charge of the prison ship Falmouth. When the Brown University Medical School was orRantzed in 1812, Doctor Wheaton be came professor of medicine in that institution. He was a sound practical physician, a Oneclassical scholar, and a writer of ability. He died In Providence in the year 1851. 444 Vol. XVII. PLEADWELL USHER PARSONS. His naval experience had turned his attention particularly to sur gery. In European hospitals he appears to have observed surgical * cases almost exclusively. As an operator he was more marked for caution than dexterity, and was particularly methodical in the preparation and arrangement of instruments and dressings. He used to point out a house in Smithfield where he first operated for strangulated hernia in 1823. Being little acquainted with the oper ation, he studied it up, perhaps, in Scarpa's treatise, which he had bought in Paris, while the messenger was conveying him to the house. In the American Journal of Medical Sciences, 1848, he pub lished a summary of his large surgical operations. He reports 15 cases of herniotomy, with 11 recoveries. He performed lithotomy only once and successfully on a patient in Apponaug, aged 74 years. He tied the common carotid artery for a supposed tumor in the brain, producing intense headache and total blindness ; the symptoms were relieved, but returned and ended in death. He extirpated the eye ball, with the lachrymal gland and much of the other textures in the orbit, as was then the common practice, instead of the milder process of enucleation. He operated frequently for cataract. He was at one time much interested in the surgical treatment of de formities and performed tenotomy often. He contrived and used with fair success an apparatus for securing a union in cases of cleft palate. It was only in the latter part of his professional career that he enjoyed the advantages of etherization in surgery. He never became so fully at home with it as the later generation of surgeons. In the greater part of his operations the only anaesthetics at his command were such as laudanum and brandy and words of encouragement and sympathy. While in active practice he gave a great deal of attention to private pupils in medicine, having often several at a time and more than 50 in all. He very commonly had private dis secting classes in the winter. After becoming well established in practice, Doctor Parsons al lowed himself more liberty in regard to absence from Providence than is usual with equally busy physicians. In the autumn of 1843 he visited Europe for the third time, contemplating a journey to Egypt, but going no farther than Paris, where his son was studying medicine. He spent some days in London on his outward journey, renewing his acquaintance with Mr. Clift and attending a meeting of the Geological Society, where he saw Doctor Buckland, whose Bridgewater Treatise he had read with great interest. In Paris he frequented the hospitals and took copious notes of surgical cases, as he had done 24 years earlier. A few extracts from his diary show the character of his observations : There is to my mind an unaccountable aversion on the part of French sur geons to attempt uniting wounds after operations, by the first intention. To No. 3. 445 PLEADWELL USHER PARSONS. clay, the flaps made in the amputation might have been brought together, a depending opening left, and the whole or nearly all the wound closed- ; instead >f which the old system in vogue twenty -three years ago Is continued, of itufling the wound with charpie or lint. There is in French surgeons an indifference to life that seems inhuman. They operate when they should not; when they must know that the advantages to be gained are not to be compared with 'the risk of life, and the certain amount of severe pain that must be suffered from the operation. He bought several valuable instruments and anatomical prepara tions in Paris. He also bought a copy of Josephus, printed by Schussler at Augsburg, 1470 ; " and the Annals of the World's His tory, printed by Walch at Venice, 1479, and adorned with woodcuts representing the Tower of Babel, Nineveh, Solomon's Temple, etc. He was in Paris from November 19, 1843, till February 19, 1844, when he set out for London. He there received polite attentions from Mr. Richard Owen, Bransby Cooper, Mr. South, Dr. John Forbes, and other distinguished surgeons and men of science; visited the largest hospitals, and attended a meeting of the Royal Society. He left London March 8 for Liverpool, Glasgow, and Edinburgh. Re turning to Liverpool he there passed several days in the agreeable society of some old American friends and sailed April 4, bearing dis patches from the minister, Mr. Everett. He arrived in Providence April 22, 1844. Doctor Parsons joined the Rhode Island Medical Society in 1823. In 1837 he was elected president of the society for three years, with out having passed through the usual stages of vice presidency. He was a constant attendant at its meetings, and contributed several papers to its transactions. These were mostly on strictly medical subjects. One had a semihistorical character. In 1859 a committee was appointed to prepare sketches of eminent deceased physicians of Rhode Island; and Doctor Parsons, as its chairman, compiled from various sources a pamphlet on this subject. It contains notices of nearly 40 physicians who lived on the island of Rhode Island, mostly in Newport; of the Bowens and others in Providence, and the north part of the State ; and longer articles, contributed by other writers to the chairman, on Doctors Levi Wheaton, Solomon Drowne, Peter and William Turner, Charles Eldredge, Edmund T. Waring, find David King, all deceased. His latest printed- communication to this society was a " Letter on some points of military surgery," read December 19, 1860; and re citing some of his experience on the Great Lakes. This paper would appear to have been suggested by anticipation of the Civil War. "Beloe, William: Anecdotes of Literature and Scarce Books, 1810, Vol. IV. p. 109.

When the American Medical Association was organized in Phila delphia in 1847, Doctor Parsons was present as delegate, and took an active part. In writing of the receptions then held, he says: "It was gratifying to me to find whenever I introduced myself to any stranger,—which I did a dozen times this evening, —as Dr. Par sons of Ehode Island, they all called me at once by my christian name, having read of my writings through journals." For many years he attended the annual meetings of this association, succes sively in Baltimore, Boston, Cincinnati, Charleston, Richmond, .New York, St. Louis, and Philadelphia. In 1848 he was appointed chair man of a committee on adulterated drugs ; and, in 1849, chairman of the committee on medical sciences. His report on this last subject contains a summary of the " progress of American medicine during the year." In 1853, at New York, he was elected first vice president. In 1854, at St. Louis, he acted in the place of president at the early part of the meeting, and as such delivered the opening address; the president, Dr. Jonathan Knight, of New Haven, being unable to attend. He was honorary member of the medical societies of Massachu setts, Connecticut, New Jersey, and South Carolina. Doctor Parsons was an industrious writer on professional sub jects. He wrote frequently for the premiums instituted by Ward N. Boylston, Esq., of Massachusetts, and awarded by a committee appointed by the corporation of Harvard University for disserta tions on " medical, anatomical, physiological, and chymical subjects." Four of these prizes were awarded to him, viz, for dissertations on periostitis, 1827; on eneuresis irritata, 1828; on "The connection be tween cutaneous diseases which are not contagious and the internal organs," 1830 ; and on cancer of the breast, 1835. The other subject proposed for the year 1830 was the comparative influence of animal and vegetable decomposition in producing fever. The premium for the best dissertation on this subject was awarded to Dr. Charles Caldwell, of Kentucky; but Doctor Parsons's essay on the subject was highly praised by the committee, with a wish that it might be published and its author's name made known. He also received the Fiske Fund premium in Rhode Island in 1842 for an essay on spinal diseases. These six papers were published in a volume. He contributed numerous articles to different medical journals. In 1831 he was appointed professor of obstetrics in Jefferson Medi cal College, Philadelphia, and lectured there the following winter. Some valuable models for illustrating these lectures were lost at sea, on their way to Philadelphia. The subject was one for which his experience had not particularly qualified him. He did not after No. 3. 447 PLEADWKLL- —TJSHEK PARSONS. ward accept any appointment which would require him to reside away from Providence. Doctor Parsons had long been impressed with the need of a gen eral hospital in Providence and he played a prominent part in secur ing a State charter for this institution and in obtaining bequests for its support. When the Khode Island Hospital was organized he gave $1,000 to it. He followed the progress of the undertaking with great interest, though he had then withdrawn from medical practice. He gave about 300 volumes to its library and bequeathed it $100 by will. He was at first appointed at the head of its consulting staff. Doctor Parsons had too active a mind to rest satisfied with the knowledge required for everyday medical practice. He investigated many subjects more or less connected with his professional studies. When the doctrine called phrenology was presented in Boston, graced by the zeal and eloquence of Spurzheim, Doctor Parsons gave much attention to it. Dr. Jonathan Barber gave a course of phrenological lectures in Providence ; and Doctor Parsons followed him in a short course, illustrat«d by many crania and models, describing the anat omy of the brain and concurring in the general principles of phre nology, but opposing the extravagant claims of the so-called science. In 1837 he obtained a charter for the Rhode Island Natural His tory Society, of which he was chosen the first president. It held sev eral meetings and made some collections, but never attained the posi tion of a working scientific society. He kept up the practice of col lecting specimens. He purchased and read the geological works of Buckland, Hitchcock, and others. He had some knowledge of field botany, and occasionally gave private courses of botanical lectures to classes of young ladies. In 1831 he prepared an address on temperance, which he de livered in Providence and other places, and which was afterwards published. In 1840 he lectured before the American Institute of Instruction, at its meeting in Providence, on the connection and reciprocal influence of the brain and stomach. In this as in other addresses partaking of a physiological character, he dwelt much on the doctrines of Bichat, whose treatise, " Sur la Vie et la Mort," had made a great impression on his mind, and was habitually rec ommended by him to his medical pupils. His reading on subjects not connected with physical science was mostly in works of history and travel. He took little interest in purely imaginative literature. He read few of the classical novels. A special interest in the remains of Pompeii, which he had care fully examined when cruising on the Mediterranean, led him to buy and read Bulwer's Last Days of Pompeii. In poetry, his favorites were Thomson and Young. He often read through the " Seasons " 448 Vol. XVII. PLEADWELL USHER PARSONS. as the seasons came around, and was equally familiar with the " Night Thoughts." He selected the opening lines of this poem for his son to speak at a school declamation when less than 10 years old ; and it will be readily believed that they were not very intelli gently or impressively uttered. He was also a regular reader of the Bible. Besides frequent recurrence to certain favorite parts, especially in the Psalms, he read through the Bible, with probably some omissions, four times in the last 30 years of his life. He thus wrote in his notebook November, 1837 : I have this day finished the Old Testament, which I began in June 1837. I cannot but think that the Christian religion would gain by excluding some of the books. Two-thirds of what follows the first chapter of Jeremiah might be omitted, and all of Solomon's Song. These writings of the Prophets might be transferred to the Apocrypha, or incorporated into a separate division of the Bible, and considered as elegies on the woes prepared by Divine Power to bring upon this ill-fated people the Jews. The Bible, after such an exclu sion, would be read more generally, intelligibly and thoroughly, than It Is while encumbered with such a mass of matter so irrelevant to subsequent ages of the world. As a rule of life, and a history of God's government and the plan of salvation, an abridged volume might be formed for general circulation, which would embrace all that is essential. I shall now commence reading Tyndall's New Testament with notes. His ecclesiastical relations were peculiar. He was brought up in congregational worship and the faith of the Puritans.22 Soon after his marriage he was admitted to the Episcopal communion at St. John's Church. In later years he had a seat in one place of worship after another—St. John's, the First Baptist, St. Stephen's (now Church of the Saviour), and the Central Congregational Church. For the last 12 years of his life the latter was his usual place of attendance on Sundays and the only one where he owned a pew, though he frequently partook of the communion of the Episcopal Church. He often went to other churches, especially the Unitarian, under the ministry of Dr. Edward B. Hall, whose preaching he much admired. After hearing him on Thanksgiving Day, 1853, he wrote in his notebook : " I wish he and other Unitarians would follow after St. Paul's example and preach a little more about Christ and Him crucified. At the same time, I wish orthodox would preach more practical sermons and not be forever harping on particular doc trines of the Calvinistic order." In his busiest years of practice he was remarkably regular in attending church once or twice on Sunday. He seldom took an active part in politics. He voted with the Whig Party in its day. The nomination of General Harrison for President awakened a special interest in him on account of the general's con- " His grandfather, the minister of Bradford, was suspected of Armlnlanlsm.

Doctor Parsons wrote several newspaper articles in favor of Harrison which were widely reprinted and spoke on the same subject in the old town hohse October 19, 1840. He was appointed messenger to carry the electoral vote of Rhode Island to Washington and handed the package of votes to Vice President Richard M. Johnson. When the suffrage troubles arose in Rhode Island he did not share in the attachment felt by many natives of this State to the charter of 1663, and his sym pathies were with the movement for enlarged suffrage. Mr. Thomas W. Dorr23 was his intimate friend. But when the affair took on a revolutionary character he rallied to the support of the existing gov ernment. He acted as volunteer surgeon of the marine artillery. The subsequent imprisonment of Mr. Dorr was exceedingly distasteful to him. He exerted himself to procure his release by circulating peti tions, etc. ; but his course did not suit the uncompromising views of Mr. Dorr, and was unavailing. Immediately after the passage of the act of liberation he visited Mr. Dorr as physician and friend. On the outbreak of Civil War. in 1861, he offered his services as surgeon, in a letter to Governor Sprague. He was commissioned, in June. 1861, surgeon of the Providence Horse Guards. He followed the various fortunes of the conflict with intense interest. At the time of the presidential election in 1868, his last illness had begun; he had been confined to the house 16 days, and walked with difficulty. The warden came down from the wardroom, and met him in the lower entry, where a chair had been arranged, and he gave his last vote for Grunt and Colfax. From an early age he was interested in tracing the history and genealogy of his family. Till the year 1834 he did not correctly fol low up the line beyond his great-grandfather. Rev. Joseph Parsons, of Salisbury. In that year, he carried on a lively correspondence with the eminent antiquary of Northampton, Sylvester Judd, Esq. Mr. Judd's valuable letters helped him to connect Joseph Parsons, of Salisbury, with the first Joseph, of Springfield, and the second Joseph, of Northampton. He explored old graveyards, old records, and all written sources of genealogical lore. He visited the towns where his ancestors had lived, talked with the old men of those places, and treasured up the knowledge he had learned from their trembling lips. A manuscript book is still preserved, in which he wrote out the his tory of the families of Parsons. Frost, Usher, etc., with sketches of the lives of individuals, and preserved autographs of many. In 1838. he printed on a sheet an outline of the " Genealogy of the fam ily of Joseph Parsons." "The leader of the so-called Dorr's rebellion, in the year 1842, 450 Vol. XVII. PLEADWELL USHER PARSONS. In 1849, he prepared a somewhat elaborate memoir of Maj. Charles Frost, his great-great-grandfather, who was a man of some im portance in civil and military affairs, and was killed by the Indians in Kittery, now Elliot, July 4, 1697. This was published in the New England Historical and Genealogical Kegister, July, 1849. It was founded on materials drawn from old manuscripts obtained in Maine, especially the voluminous papers left by Frost's son-in-law, Capt. John Hill, who commanded Fort Mary, at Saco, from 1693 to 1700. It contains, from the original in his possession, the account of Major Frost's death, written to Captain Hill by Joseph Storer, who was another son-in-law of Major Frost. Doctor Parsons afterwards prepared a genealogy of the Frost family, and an account of " the descendants of Peter Hill, of York County. Maine, with some inci dents relating to the French and Indian wars," founded on the same Hill papers. His most important literary undertaking, the " Life of Sir William Pepperrell," sprang originally out of his genealogical stud ies. He began to prepare for this task in the year 1846. but sus pended it on learning that Pepperrell's life would be written by others. The principal exploit of Pepperrell. in heading the attack on the French fortified town of Louisburg, in 1745, and reducing it after a siege of 48 days, had been fully described by Belknap and other historians. But no extended memoir of Pepperrell had been published. Rev. Dr. Charles Burroughs, of Portsmouth, N. H., and Hon. Lorenzo Sabine, of Framingham, Mass., had both prepared sketches of his life. A connection of the family. Col. George Spar- hawk, of Kittery, where Pepperrell's mansion still stood, had talked of writing his biography, and was known to have a great many of his papers, which had lain neglected in a shed or fish house on the estate, till Colonel Sparhawk selected and arranged the more valu able documents. It was after correspondence with these gentlemen and many others that Doctor Parsons determined to carry out the undertaking. He read the State and local histories bearing on his subject, examined the papers in the Massachusetts Historical Society and other public places of deposit, and procured documents from all available sources. The Sparhawk papers, after some negotiation, reached his hands in January, 1851, through the kind offices of Mr. John Blunt, of New York. For four years after that he gave much of his leisure to this work. Not satisfied with studying the details of Pepperrell's career in its written and printed records, Doctor Parsons visited the harbor and ruins of Louisburg in August, 1852, in company with his nephew, Edwin Parsons, Esq., of New York. They took the English steamer from Boston to Halifax, and then a small steamboat to Sidney, Xo. 3. 451 PLEADWRLL USHER PARSONS. driving thence to Louisburg. An account of his observations there is given in the Life of Pepperrell. At the beginning of the year 1855, his book was essentially com pleted, and had been submitted to the friendly criticism of several historical scholars, especially Hon. Mr. Sabine, before mentioned, and J. Wingate Thornton, Esq., of Boston. It was published in May. It was very favorably received by students of colonial history, both in America and England, and was kindly noticed and sompwhat copiously analyzed in the leading newspapers and magazines of this country, and in the London Athenseum. The subject being, ante- revolutionary, was interesting both in the mother country, where several descendants of Pepperrell still lived, and in America. It was republished in London in 1856. Most of the reviews of this book consist mainly of an analysis of its contents, and are hardly fitted for mention here. The following few sentences from a discourse delivered before the Rhode Island Historical Society, by its president, Hon. Samuel G. Arnold, the author of the History of Rhode Island, give one a very good idea of contemporary opinion on this work : This work is a very important contribution to our colonial history. The conqueror of Louisburg was one of the foremost men that America has pro duced. A merchant of vast wealth, whose landed possessions alone extended thirty miles from the Piscataqua to Saco, acquired by his own skill and indus try; a soldier whose genius was attested by success in capturing the stronghold of France from its powerful defenders; a civilian whose talents were every where admitted to be of the highest order. Sir William Pepperrell was the only native of New England who was created a baronet during our colonial period. The eclat of the war of Independence, has dimmed the fame of the great names of ante-revolutionary days, and whoever aids to rescue from ob livion the achievements and the characters of the mighty men of the past, con fers a favor upon humanity, and adds an enduring page to the volume of history. This Dr. Parsons has done in the memoir of his illustrious ancestor. * * • To revive the memory of these school-days of the republic, and to bring before us the men who led in that era of our national pupilage, and who formed the mind and trained the muscle of the growing state, is a pious duty which Dr. Parsons has well performed. He left in manuscript a history of his native town of Alfred. When a celebration of the hundredth anniversary of the settlement of that town was contemplated, in 1860, he was asked to prepare a historical discourse, but declined on account of impaired health. For many years, he interested himself in studying the remains, language, and customs of the aborigines of this part of our country. The first record of his meeting with Indians is in the diary of his march from Albany to Buffalo, in 1812. He there writes. October 7, being on the route between Vernon and Whitestown : Passed by the Oneida tribe of Indians, consisting of about two thousand . souls. The warriors have volunteered their services to assist in prosecuting the war against Canada. Their dress is a shirt which does not extend the length 452 Vol. XVII. PLEADWELL USHEB PABSONS. of the trunk, a cloth pinned around the waist, and extending over perhaps a fourth part of the lower extremities, a pair of broadcloth leggins, moceasons, and a blanket thrown over the body. Their huts are one room, in which are one bench, kettle, pail, dish and samp-mortar. The tribe have two schools at tended by all the children, and a church. The conversation of the warriors I could understand, but not of the squaws. This difference may be imputed to the circumstance that the warriors have more intercourse with the white people. In Iii s rides extending many miles around Providence, he examined the Indian burying grounds, and gradually made a collection of bones, and various utensils, such as hatchets, arrowheads, pots of soapstone, etc. He recorded the Indian names of localities, with the meanings that had been assigned them by tradition or by guess. In 1840, he furnished a barrel ful of skulls, from an aboriginal burying place in Washington County, to Dr. Samuel G. Morton, of Philadelphia, author of Crania Americana. After his principal historical work was published, and when he was about 70 years old, he began to collate and arrange his notes on Indian localities in Rhode Island. He made new researches on this subject, and by examination of various maps, of historical works relating to Rhode Island, and old records, collected many new names, with supposed explanations of some. At length, in 1861 he published a pamphlet of 32 pages, entitled " Indian Names of Places in Rhode Island." It contains more than 300 titles ; but some of the names are repeated in different applications ; thus, the name Pettaquamscot re curs as given to a river, a tract of land, and a rock. There are a few repetitions from inadvertence, sometimes concealed by an unim portant variation in spelling. In a preface he says : No attempt is herein made, by the author, to examine Indian names of places as a philologist, or grammarian, but merely to gather such as were in existence when civilization commenced within the State of Khode Island, according to its present boundary ; and, in a few instances, give the meaning or derivation of the word used. I was led to this enterprise, partly for the amusement it might afford in my leisure hours, but more for the purpose of rescuing from oblivion names of places in use among the aborigines, and for the convenience of those who may hereafter wish to apply them to their country villas, factories, or institutions, as has often been done in this and other states. As early as the year 1841 he visited the Indian burying ground and old fort in Charlestown, R. I., and made some examination of Indian graves. He went there several times in subsequent years, procured various Indian relics, wrote out descriptions of the places, and took part in some attempts at disinterment. In 1860, and again in 1861, he made these entries in his diary : Saw the old Indian burying-ground and fort, and the articles lately dug up from Indian graves, as coins, wampum-peag, kitchen utensils, chains, iron and silver. * * * Six of us went to the place and worked with spade till near midnight. Took up a well preserved skeleton, eight feet deep. .No.3. 453 PLEADWELL—USHEB PAKSONS. When some Indian graves were afterwards opened by another party, Doctor Parsons bought many of the bones and articles found with them, and retained some in his possession at his death. He prepared a paper on this subject, which he read, exhibiting many of the relics, before the historical societies of Rhode Island and New York. This paper was published in the Historical Magazine, Feb ruary, 1863. It describes the customs of the Indians in regard to burial, sketches the history of the Narragansett Tribes, and their intercourse with the Dutch, and particularly of Sachem Ninigret and his descendants, and gives a minute account of the discoveries made in the ancient Indian burying ground, believed to have been the sachem's cemetery. He states the reasons for supposing that the grave in which the most curious articles were found was that of Sachem Ninigret's daughter; and that the adjoining grave was that of the sachem himself, who was living when the country he inhabited was first settled by the English. Doctor Parson's various labors were recognized by his election to many literary and historical societies. He was a corresponding mem ber of the historical societies of Maine, Massachusetts, New York, New Jersey, Georgia, and Wisconsin, the American Antiquarian So ciety, The Academy of Natural Sciences, etc. He was an active mem ber of the New England Historical Genealogical Society and was its vice president for Rhode Island from September, 1864, till his death. He joined the Rhode Island Historical Society in 1825 and was a use ful member of it, making many contributions to its collections and reading several papers at its meetings. It is well known that a controversy arose between Commodores Oliver H. Perry and Jesse D. Elliott in relation to the conduct of the latter in the naval battle of September 10, 1813, and that long after Perry's early death the credit of victory was claimed for Elliott by himself and his friends. Doctor Parsons took a warm and active interest in this dispute. He was strongly attached to Perry and con vinced that Elliott's conduct was disgraceful. In conversation, by newspaper articles, by contributions to writings published by others, and lastly in a public historical address he vindicated the claims of Perry and the truth of history as he understood it, often in terms reflecting severely on Elliott and his defenders. In January, 1836, Tristam Burges read a discourse before the Rhode Island Historical Society in which he gave a vigorous account of the battle. In 1839 this was published with copious notes and dia grams of the battle in different positions. Some of these notes were furnished by Doctor Parsons. The "extract from the log book of the Lawrence" was taken from his diary. He contributed many notes to the " Life of Commodore Perry," published in 1840 by Alex ander Slidell Mackenzie. 646—22 6 PLEADWELL— USHER PARSONS. Vol. XVII. In 1852, having been invited to deliver the stated annual discourse before the Rhode Island Historical Society, he chose for his subject " The history of the battle of Lake Erie." " I have made this choice," he says, " first, because this battle is a part of Rhode Island history, and therefore appropriate to the occasion ; secondly, because I could speak of it from personal knowledge; and thirdly, because a very inaccurate and perverted account of it has been written and imposed upon the public by the late J. Fenimore Cooper, esquire," He narrates the circumstances which led to the formation of a fleet on Lake Erie, the difficulties under which it was created and got afloat, and the reasons why it is regarded as belonging to Rhode Island history. He relates the incidents of the battle quite fully and then attacks Elliott and Cooper in a style of indignant sarcasm. In the words of Mr. Arnold, " He has done this in a style that leaves nothing to be said upon the points in dispute. His own testimony is direct and incontrovertible. His reply to the assaults of Cooper is comprehensive and complete. A certain irony pervades this por tion of the address, which is the appropriate weapon wherewith to treat mendacity of statement when brought to the support of cow ardice of conduct and infamy of character." Doctor Parsons had always a fondness for written controversy and could handle the caustic pen as well as the scalpel or saw. In his more advanced life he became well known in the growing cities along the southern shore of Lake Erie. He often visited that region after his retirement from active practice. Those cities appre ciated more and more the importance of Perry's victory, and com memorated its anniversary by yearly gatherings, and occasionally by special observations and various plans for the erection of monu ments. Doctor Parsons was the only surviving officer of the battle who had cultivated historical tastes and possessed the powers of writing and oratory. In 1858, the anniversary was celebrated at Put in Bay Island, near Sandusky, where Perry's fleet had anchored the night before the battle. There was a very large assemblage, and a brilliant display of yachts and steamers. Hon. Salmon P. Chase presided at the ceremonies on the island. Eloquent addresses were made, and three surviving officers appeared on the platform, Captains Champ- lin and Brownell speaking briefly, while Doctor Parsons read an elaborate narrative discourse. This was received with a great deal of interest by the large audience, and was afterwards printed in all the principal newspapers of Buffalo, Erie, Sandusky, Cleveland, etc. He afterwards wrote in his notebook, " this anniversary was among the most delightful of my life, as well as most interesting." Two years later the forty-seventh anniversary was celebrated at Cleveland. That city alone successfully carried out the plan of No. 3. 455 PLEADWKLL USHER PARSONS. erecting a monument to Perry, which on that day was dedicated. It stands in the park at Cleveland, and consists of a statue of Perry, and of other appropriate sculptures. The dedication, September 10, 1860, was very largely attended. The governor of Khode Island, with many of her civil and military officers, were present by special invitation. The two most important features of the literary exer cises on that day were the oration by Hon. George Bancroft and a historical address by Doctor Parsons. These three discourses relating to the battle of Lake Erie all give the story in essentially the same way, and show some unavoidable repetition. The two delivered at Put in Bay and Cleveland were not. however, controversial. In his later journeys along Lake Erie, Doctor Parsons was re garded as a guest of the public, and was passed and entertained as such on the steamboats and railroads. These various acknowledg ments of his early services, and the kind reception of his historical discourses, after he had passed the age of 70, gave him the keenest pleasure. ^ome other published writings, less known than those before mentioned, attest his permanent interest in his naval reminiscences. In 1836 he contributed to the Naval Lyceum, New York, an article on quarantine. In 1840 he published in the Knickerbocker Maga zine, a story. " The Avenger of Blood," founded on an incident that occurred on board the Guerriere in 1818. In 1850 he helped to agi tate the question of the abolition of flogging in the Navy, and wrote a pungent article on the subject for a New York newspaper. In 1862 he contributed to the New England Historical and Genealogical Register " Brief Sketches of the Officers who were in the Battle of Lake Erie." A sketch of Doctor Parsons's career would be very incomplete if it did not allude to the tenacity with which he clung to early attach ments, and the pleasure he took, during his mature and declining years, in revisiting the scenes of his boyhood and youth. Almost every summer, after he had gained an established position in Provi dence, he went to his native place and the neighboring towns, where lie had struggled with poverty and youthful ambition. No recrea tion gave him greater pleasure. He kept up intimate intercourse and correspondence with the relatives who still lived the.re. He also reverted with the deepest interest to the region about Lake Erie, where he had laid the foundations of success. He re visited this region several times, beside the occasions already re ferred to. when he delivered historical discourses. In 1835 he made u tour to Lake Erie, in company with Capt. Daniel Turner, who commanded the Caledonia in the battle of September 10, 1813. They went from New York to Albany by steamboat, and thence to Black 456 Vol. XVII. PLEADWELL USHER PARSOXi Rock by canal. The journey by canal occupied three days. Doctor Parsons minutely describes, in his diary, the localities at Black Rock, and enumerates the houses that were standing there in 1812, most of which were destroyed by fire in December, 1813. He could not determine the exact location of the barracks where he had been lodged in 1812. He was joined at Buffalo by Capt. Stephen Chanip- lin, who commanded the Scorpion in the Battle of Lake Erie.24 They visited the Queen Charlotte, captured from the British in that battle, and afterwards sunk in the lake. "A company of merchants lately bought the ships, and have raised the Queen and refitted her. The captain received us politely, and gave us some pieces of oak from her to make walking canes. Captains Turner and Champlin and myself made out an inscription to be put on a gilded cannon ball that is to be slung in her cabin. Said ball was taken from among her timbers ; and, as we stated, was fired by the Tigris.''' In 1836 Doctor Parsons went to the West in behalf of the " Smith- field Emigrating Land Company." He thus writes, September 4. 1836: "About three weeks since, I caught the western land-fever for speculation, which has ever since occupied my thoughts. Two weeks yesterday I attended a meeting at Scott's pond, and bought four shares. I was chosen member of the purchasing committee, to have my expenses paid." He was absent about seven weeks, went from Buffalo to Detroit, thence to Toledo, where he bought a horse for $60, a saddle, bridle, and blanket for $12. He then traveled horse back to Fort Wayne, Laporte, Chicago, Danville, and Indianapolis. His expenses on this journey, as charged to the company, were $311.25, including the purchase of horse and outfit, which were sold for $41. He then and subsequently bought land at different points in Western States ; and some of these investments, after entailing a long-continued burden of taxation and other expenses, became profit able many years later. In 1838 he revisited Erie, after an absence of nearly 24 years. In his diary he mentions Cayuga Lake as almost the only place on his route to Buffalo which he recognized as having seen on his early march. He arrived in Erie late in the evening of July 5. " Friday. 6th, visited the court house at seven o'clock. Here I received nay wounded of the fleet about the 20th (24th) of September 1813." He called on many persons with whom he had been very well acquainted for two years; only one recognized him without aid, though many expressed great joy in meeting him. In the burying ground he » Capt. Daniel Turner, born at Staten Island, N. T., Aug. 8, 1792, died In Philadelphia, Feb. 4, 1850. Capt. Stephen Champlin, born in South Kingstown, R.

No.3. 457 PLEADWEIX USHER PARSONS. looked for the graves of Claxton, who died of a wound received in battle, and of other naval comrades. He writes : I called on Captain Dobbins, who was a sailing-master in the war, now commander of the revenue cutter. I went with him to the Peninsula, (Erie was formerly called Presqu'isle, ) and trod once more the deck of the Latcrence, now a hulk resting about east a quarter of a mile from the old blockhouse. H*r deck is in a sound state ; but the water conies nearly up to it. so that I could not see her hold. In this vessel I sailed in 1813, and was in battle. She was repaired the following year, and I went in her to Mackinac with troops under Colonel Croghan. She was sunk and remained no till within the last two or three years, when she was raised and proved to be perfectly suond. Took some pieces from her to make canes of. The following day he visited James Miles, whose arm he had am putated the day after the battle on Lake Erie. " He did not recol lect me, but on learning who I was shed tears of joy." His diary concludes thus : This visit to Erie gave me indescribable pleasure. The thousand associa tions of pleasure and of pain ; the fresh recollections of events, as if they transpired but yesterday, which a thousand objects served to call up, and many of which would but for this visit never have been revived ; the pleasure afforded in taking old friends by the hand, after a separation of twenty-four years ; the changes in looks ; the changes in worldly condition for better and for worse ; the grave-yard where lie the bodies of great numbers of early friends ; the changes and vast improvements about the city, —elegant houses and churches where there were then but a few humble dwellings, —all, all tended to render my stay here one of the most Intense interest, on many occasions so powerful as to take from me the power of speech. Hut what shall 1 say of the protecting mercy of Him who through dangers seen and unseen, perils by land perils in the deep, lias surrounded my path, and preserved me to the present moment? May the remainder of my days be more devoted to His Service. In 1854, after attending the meeting of the American Medical Association at St. Louis, he journeyed to Chicago and St. Paul, visited the Falls of St. Anthony, and returned by the way of Buffalo, -Montreal, and Quebec. The next year he went to Lake Superior with his nephew, Edwin. On his way he rehearsed on the spot his adventure in the capture of Fort Erie in 1813. He stopped at Macki nac and Sault Ste. Marie, and examined and described the copper mines at Lake Superior. For several years before his death Doctor Parsons was almost wholly withdrawn from active practice, though he sometimes visited in consultation and even performed some surgical operations. His last amputation was of the forearm, performed when he was 74 years old in Rehoboth. His sturdy health of body and mind gradually failed, but with very little suffering, and with many circumstances fitted to make old age happy. An increasing forget- fulness in regard to business matters, and hesitancy in speech and uncertainty in locomotion showed that his powerful brain was yield 458 Vol. XVII. PLEADWELL — USHER PARSONS. ing to the natural changes in its texture; but he still enjoyed reading, frequented the Athenaeum, called at the houses of a few familiar friends, kept up a rather extensive correspondence, visited his near relatives in Maine and New York City, and interested himself in watching the progress of the Rhode Island Hospital. The exercises at the opening of this hospital took place October 1, 1868. He was conducted to a seat on the platform, and was kindly referred to in Professor Gammell's eloquent discourse. This compliment, the last he was ever to receive on any public occasion, gratified him very much. He wrote in his diary the next day with a trembling hand, " I feel very happy for yesterday's doings." He was present at the first important surgical operation performed there October 10. On the evening of October 17, after exposure to cold, he had a severe, acute attack, involving the brain, and followed by persistent nausea, headache, and confusion of mind. He first left the house after this, November 3, when he voted at the presidential election. He continued to go out almost every day for a month more, but with feeble and uncertain steps and a degree of mental disorder that gave his family great anxiety. From December 4 he was again confined to the house, and mostly to his chamber, and died on the morning of December 19, 1868, aged 80 years and 4 months. He was very faithfully attended on the last sickness by his friend Dr. Stephen S. Keene. An autopsy showed chronic degeneration in the arteries and membranes of the brain and acute inflammatory dis ease in the cerebellum. This last probably dated from the 17th of October, and was the immediate cause of death. His funeral was kindly attended by Rev. J. G. Vose, of the Beneficent Congregational Church. He was buried in Swan Point Cemetery. On the 1st of June, 1869, Hon. Samuel G. Arnold, President of the Rhode Island Historical Society, read before that body, in accordance with pre vious appointment, a discourse "On the services of three distin guished members of the society who died during the year 1868," Albert Gorton Greene, William Read Staples, and Usher Parsons. The portion of it referring to Doctor Parsons closes with the fol lowing sentences : Probably no man now living has so complete a knowledge of Indian traditions and history or is so competent to interpret their meaning as was Dr. Parsons. In his later years he retired from prac tice and devoted his time to these favorite pursuits, often making long journeys, even beyond the Mississippi River, always returning with some new discovery in Indian lore and some vivid impressions of the growing greatness of our country. He was a man in whom the love of country was strongly marked and whose fidelity to the flag never faltered in the darkest hour. His was a genial tempera ment and a kindly heart, with much of the jovial spirit of the seas in his hours of relaxation. We miss his familiar form in these seats Xo. 3. 459 PLEADWELL tTSHER PARSONS. at our stated meeting, and we miss his cordial greeting and his honest smile in the daily intercourse of life, for there are few fam ilies in this city where he was not a welcome guest and where during his long residence of nearly half a century among us his name had not become as a household word. Loved in life and honored in death, his memory will be revered by all who value those high qualities of manhood which were united in his character. BIBLIOGRAPHY OF DR. USHER PARSONS' PUBLICATIONS. 1.

OX THE TREATMENT OF SYPHILIS WITH BISMUTH SALTS. Sazerac and Levaditi, of the Pasteur Institut. Paris, have recently proposed the use of tartrobismuthate of potassium and sodium, con taining approximately 50 per cent of bismuth, for the treatment of syphilis. In their preliminary work on rabbits (infected with Spirochaeta pallida and S. cwmculi) they found that the only safe and efficient method of administration was by the subcutaneous or intramuscular route. Intravenous injections were shown to be dan gerous on account of the markedly toxic action of the drug. In order to decrease this danger as far as possible they substituted a suspen sion in oil of the drug for the watery solution. This was found to be the method of choice in the treatment of human cases on account of increased tolerance and less local reaction. Fournier and Guenot have tested the value of this treatment of syphilis on a comparatively large scale and report the results of the treatment in about 200 cases. In cases of primary sores the treponema disappeared as a rule after the second injection; in some cases even after the first. The small erosive chancres healed completely in a few days ; the medium- sized chancres in one to two weeks. The large or ulcerative chancres persisted about three weeks, but they lost rapidly their specific char acters and soon appeared as ordinary lesions, the time of healing depending on the size of the individual ulcer. The local induration and the adenopathy were influenced more rapidly by bismuth than by any other treatment and disappeared often completely within a few weeks. In no cases where the treat ment was regular did secondaries appear. The Wassermann reac tion became negative and remained so for the period of observation. 461 462 Vol. XVII. EDITORIAL. In cases of secondary syphilis the mucous patches disappeared after the first or second injection. The hypertrophic patches dried up in a few days, faded and were resorbed in 10 to 25 days, according to the amount of new tissue formation. If the treatment was com menced during the appearance of the roseolar rash this was arrested in its development, sometimes after an exacerbation of 24 hours. Herxheimer's reaction might also appear near the papular syphi- lides. The simple roseolar rash usually disappeared in 5 to 10 days ; the papules took a little longer to be absorbed. The authors have seen a generalized miliary eruption and palmar syphilides, manifesta tions which as is well known are rebellious to specific treatment, dis appear in two weeks. The general secondary manifestations — headache, bone pains, etc. —always yielded to the first injection. The authors mention eight cases which had not yielded to arsenical and mercurial treatment, but which readily responded to the bismuth treatment. They also had a case of acute syphilitic meningitis with all the characteristic symptoms. After four injections the clinical improvement was complete. After two weeks of treatment the lym phocytes in the spinal fluid had been reduced from 400 to 7 per cubic millimeter. Lesions of tertiary syphilis, gummata, osteoperiostitis, and ulcers yielded, as a rule, very rapidly to treatment. In cases of visceral and nervous lesions the time allotted to treatment has been too short to enable the authors to express an opinion. In their discussion of the effect of the bismuth treatment on the Wassermann reaction, Fournier and Guenot show that the clinical improvement of the cases is accompanied by a marked change in the serological test. Seventeen primary cases received their first injec tion while the Wassermann was still only partially positive. In 10 of these cases the Wassermann became actually negative; in the oth ers it weakened markedly. In 18 other primary cases with frankly positive Wassermann, 6 became completely negative, while the others were weakened. The authors found it to be rare for the Wassermann to become negative after the first series of injections; as a rule it gradually grew weaker and finally became negative from the second to the fourth month. Fournier and Guenot used a 10 per cent suspension in olive oil of the tartrobismuthate of sodium and potassium. As the subcutaneous method was found to be painful, they always administered the drug intramuscularly. Due to the tendency of the drug to produce stomatitis when large doses were given, the authors recommend that a single dose never exceed 0.30 gram, and in aged and debilitated patients not over 0.10 to 0.20 gram. No. 3. 463 EDITORIAL. After the first two or three injections of 0.20 gram, a biweekly in jection of 0.30 gram seems to be good practice. Two to three grams should be injected during a month. After the first series of injections the treatment could be contin ued with a single weekly injection of 0.20 to 0.30 gram, or be sus pended for a month to be recommenced again in the same manner as described above. One should follow the progress of the treatment by repeated ex aminations of the blood and check up every case at subsequent regular intervals. With regard to untoward effects of this treatment the authors state that they have given over 1,500 injections without having expe rienced any really important mishap. In cases of grave visceral lesions, and especially where the renal function is impaired, one should proceed with caution. A slight elevation of the temperature was seen in some cases the day after injection, accompanied with pain in the back, but no general reac tion was observed. After the first four injections a moderate poly uria occurred in a few instances. The only two manifestations that might cause some trouble are local reactions and the stomatitis. The former were seen in a few patients who walked too much imme diately after the treatment. The tendency to stomatitis can be very well controlled by hygienic measures of the mouth. In a few cases dark spots of bismuth impregnation were seen on the mucous mem brane of the mouth. The bismuth has been recovered from the blood and cerebrospinal fluid and has been shown to be eliminated through the saliva, bile, feces, sweat, and urine. The authors state that bismuth undoubtedly is a most energetic antisyphilitic agent, having particularly marked effect not only on the infectious manifestations of the disease but also on the Wasser- raann reaction. They conclude, however, that time only will tell if this drug will prove to be of value in the radioed cure of syphilis. (EP.) ON THE CHANCES FOB SUCCESS. Edward Bok, who for 30 years so ably edited the Ladies Home Journal, is a man with a keen insight into human nature. The suc cess he attained in life was not achieved without hard work, and what he has to say on a young man's chances for success is worth reading. As a young man, so he states in his autobiography, which was pub lished last year under the title of " The Americanization of Jidward Bok," he was possessed of the idea, as are so many young men enter ing business, that the path which led to success was very difficult; 464 Vol. XVII. EDITORIAL. that it was overfilled with a jostling, bustling, panting crowd, each eager to reach the goal; and all ready to dispute every step that a young man should take ; and that favoritism only could bring one to the top. After Bok had been in the world of affairs, he wondered where were these choked avenues, these struggling masses, these competitors for every inch of vantage. Then he gradually discovered that they did not exist. In the first place, he found every avenue leading to success wide open and certainly not overpeopled. He was surprised how few there were who really stood in a young man's way. He found that favoritism was not the factor that he had been led to suppose. He realized it existed in a few isolated cases, but to these everyone had pointed and about these everyone had talked until, in the public mind, they had multiplied in number and assumed a proportion that the facts did not bear out. Here and there a relative " played a favorite," but even with the push and influence behind him "the lucky one," as he was termed, did not seem to make progress, unless he had merit. It was not long before Bok discovered that the possession of sheer merit was the only real factor that actually counted in any of the places where he had been employed or in others which he had watched ; that business was so constructed and conducted that nothing else, in the face of com petition, could act as current coin. And the amazing part of it all to Bok was how little merit there was. Nothing astonished him more than the low average ability of those with whom he worked or came into contact. He looked at the top, and instead of finding it overcrowded, he was surprised at the few who had reached there ; the top fairly begged for more to climb its heights. For every young man, earnest, eager to serve, willing to do more than he was paid for, he found ten trying to solve the problem of how little they could actually do for the pay received. It interested Bok to listen to the talk of his fellow workers dur ing luncheon hours and at all other times outside of office hours. When the talk did turn on the business with which they were con cerned, it consisted almost entirely of wages; and he soon found that with scarcely an exception, every young man was terribly underpaid, and that his employer absolutely failed to appreciate his work. It was interesting, later, when Bok happened to get the angle of the em ployer, to discover that invariably these same lamenting young men were those who, from the employer's point of view, were either greatly overpaid or so entirely worthless as to be marked for early decapitation.

Bok felt that this constant thought of the wages earned or deserved was putting the cart before the horse ; he had schooled himself into the belief that if he did his work well, and accomplished more than was expected of him, the question of wages would take care of itself. But according to the talk on every side, it was he who had the cart be fore the horse. Bok had not only tried always to fill the particular job set for him, but had made it a rule at the same time to study the position just ahead, to see what it was like, what it demanded ; and then, as the opportunity presented itself, do a part of that job in ad dition to his own. As a stenographer, he tried always to clear off the day's work before he closed his desk. This was not always possible, but he kept it before him as a rule to be followed rather than violated. One morning Bok's employer happened to come to the office earlier than usual, to find the letters he had dictated late in the afternoon before lying on his desk ready to be signed. " These are the letters I gave you late yesterday afternoon, are they not? " asked the employer. " Yes, sir." " Must have started early this morning, didn't you ? " " No, sir," answered Bok. " I wrote them out last evening before I left." " Like to get your notes written out before they get stale ? " "Yes, sir." "Good idea," said the employer. " Yes, sir," answered Bok, " and I think it is even a better idea to get a day's work off before I take my apron off." "Well said," answered the employer, and the following pay day Bok found an increase in his weekly envelope. It is only fair, however, to add here, parenthetically, that it is neither just nor considerate to a conscientious stenographer for an employer to delay his dictation until the end of the day's work, when, merely by judicious management of his affairs and time, he can give his dictation directly after opening his morning mail. There are two sides to every question ; but sometimes the side of the stenographer is not kept in mind by the employer. Bok found it a uniform rule among his fellow workers to do exactly the opposite to his own idea; there was an astonishing una nimity in working by the clock; where the hour of closing was •r» o'clock the preparations began five minutes before, with the hat and overcoat over the back of the chair ready for the stroke of the hour. This concert of action was curiously universal, no " overtime " was ever to be thought of, and, as occasionally happened when the work did go over the hour, it was not, to use the mildest term, done with care, neatness, or accuracy; it was, to use a current phrase, 466 Vol. XVII. EDITORIAL. " slammed off." Every moment beyond 5 o'clock in which the worker was asked to do anything was by just so much an imposition on the part of the employer, and so far as it could be safely shown, this impression was gotten over to him. There was an entire unwillingness to let business interfere with any anticipated pleasure or personal engagement. The office was all right between 9 and 5. One had to be there to earn a living; but after 5 it was not to be thought of for one moment. The elevators which ran on the stroke of 5 were never large enough to hold the throng which besieged them. The talk during lunch hour rarely, if ever, turned toward business, except as said before, when it dealt with underpaid services. In the spring and summer it was invariably of baseball, and scores of young men knew the batting averages of the different players and the standing of the clubs with far greater accuracy than they knew the standing or the discounts of the cus tomers of their employers. In the winter the talk was all of danc ing, boxing, or plays. It soon became evident to Bok why scarcely five out of every hun dred of the young men whom he knew made any business progress. They were not interested ; it was a case of a day's work and a day's pay ; it was not a question of how much one could do but how little one could get away with. The thought of how well one might do a given thing never seemed to occur to the average mind. " Oh, what do you care? " was the favorite expression. " The boss won't notice it if you break your back over his work ; you won't get any more pay." And there the subject was dismissed, and thoroughly dismissed, too. Eventually, then, Bok learned that the path that led to success was wide open; the competition was negligible. There was no jostling. In fact, travel on it was just a trifle lonely. One's fellow travelers were excellent company, but they were few. It was one of Edward Bok's greatest surprises, but it was also one of his greatest stimu lants. To go where others could not go or were loath to go, where, at least, they were not. had a tang that savored of the freshest kind of adventure. And the way was so simple, so much simpler, in fact, than its avoidance, which called for so much argument, explana tion, and discussion. One had merely to do all that one could do. a little more than one was asked or expected to do, and immediately one's head rose above the crowd and one was in an employer's eye. where it is always so satisfying for an employee to be. And as so few heads lifted themselves above the many, there was never any danger that they would not be seen. Of course, Edward Bok had to prove to himself that his concep tion of conditions was right. He felt instinctively that it was, how EDITORIAL. 467 ever, and with this stimulus he bucked the line hard. When others played, he worked, fully convinced that his playtime would come later. Where others shirked, he assumed. Where others lagged, he accelerated his pace. Where others were indifferent to things around them, he observed and put away the results for possible use later. He did not make of himself a pack horse ; what he undertook he did from interest in it, and that made it a pleasure to him when to others it was a burden. He instinctively reasoned it out that an unpleasant task is never accomplished by stepping aside from it, but that, un erringly, it will return later to be met and done. Obstacles, to Edward Bok, soon became merely difficulties to be overcome, and he trusted to his instinct to show him the best way to overcome them. He soon learned that the hardest kind of work was back of every success; that nothing in the world of business just happened, but that everything was brought about, and only in one way—by a willingness of spirit and a determination to carry through. He soon exploded for himself the misleading and comfortable theory of luck; the only lucky people, he found, were those who worked hard. To them luck came in the shape of what they had earned. There were exceptions here and there, as there are to every rule; but the majority of these, he soon found, were more in the seeming than in the reality. GeneraUy speaking—-and, of course, to this rule there are likewise exceptions, or as the Frenchman said, " All gener- alizations are false, including this one" — a man got in this world about what he worked for. And that became, for himself, the rule of Edward Bok's life. (W. M. K.) ON THE ELIMINATION OF DIPHTHERIA. During the year 1921 in the Navy there were 372 original admis sions to the sick list for diphtheria which, combined with 18 cases remaining under treatment from the previous year, resulted in 11,669 sick days and 20 deaths. These figures probably represent the aver age morbidity for this disease in the Navy, as it was not present in epidemic form during the year. The case mortality of 5 per cent compares favorably with the average death rate of 8 per cent exist ing among civil communities. However, the diphtheria morbidity and mortality should be lower, as the medical profession probably knows more about this disease than almost any other infection, and yet no great inroads have been made either on the morbidity or mor tality beyond what occurred after the introduction of antitoxin. We have seen yellow fever and, typhoid fever cease to be a mor bidity and mortality factor in the vital statistics of the Navy, and when the Schick test and the toxin antitoxin immunization became 468 Vol. XVII. EDITORIAL. available we had hopes of the eradication of diphtheria. Unfortu nately, up to the present time, the use of toxin-antitoxin in produc ing active immunity in recruits in the Navy is attended with consid erable difficulties and has not been considered practicable, princi pally because of the severe reaction which the toxin-antitoxin injec tion produces in adults. So naval medical officers still have to de pend on early diagnosis, prompt isolation, and the detection of car riers to keep down the incidence of this disease. However, we have not given up hope of the eradication of diph theria. We may not live to see it, but we believe that the day will come when diphtheria will be under control. Much has been written recently about the value of the Schick test and the active immunization against diphtheria by means of the toxin-antitoxin mixture. Julius Blum, writing in the American Journal of Diseases of Chil dren (1920, 20, p. 22), reports the results obtained by immunizing children, and demonstrates the fact that it is possible to render a child-caring institution diphtheria free. This has been accomplished for a period of seven years at the Home for Hebrew Infants, New York, as well as in other institutions, by injecting all susceptibles with toxin-antitoxin mixtures. Abraham Zingher, who has devoted much study to the problem of active immunization, believes that all children from 6 months to 5 years should be injected with the toxin-antitoxin, and he believes that the Schick test can be omitted in this age group, as most of the chil dren give a positive reaction. He believes that to place the diph theria preventive work on a practical basis, it is advisable at present to simplify it for the school physician by omitting the Schick test in younger children and by immunizing all children on their entrance into school. Schick testing and immunization on a fairly large scale has been carried out in the schools of New York City, and the results of this work are being watched with interest. During this procedure some interesting observations were made. It was noted that children from the homes of the more well-to-do have a much higher percentage of positive Schick reactions than those from the homes of the poorer classes who live in closely crowded neighborhoods. The highest number of positive reactions found was 67 per cent, and the per centage decreased until it was found that in the schools of densely congested districts the number of positive reactions was as low a= 16 per cent, and in one instance 13.6 per cent. Repeated exposures to the diphtheria bacillus in the congested sec tions of the city probably produce mild infections in the membranes which are not recognized as diphtheria but which may lead to the development of an antitoxic immunity. No. 3. 469 EDITORIAL. Compared with these figures are those of two private schools. In one, 79 per cent of the pupils gave positive reactions, and in a second, 85 per cent, showing that segregation of the children either in rural or well-to-do and sparsely settled sections plays an important part in the nondevelopment of natural immunity to diphtheria. This fact has an important bearing in the Navy as the majority of our recruits come from rural communities. Standardization of the diphtheria toxin for the Schick test and of heated diphtheria toxin for the control test is being advocated. Improvements in the method of immunization are possible, according to Zingher, and further work is being carried out at present to see especially whether two doses of toxin-antitoxin will give, in a con siderable number of children, results as good as those obtained with the three doses used at present. This would simplify the process and make it very convenient for general use, and it is not at all im probable that a means of preventing the severe reactions in adults will be attained. The problem to-day is one for the civil community rather than for the Navy. Zingher intimates that the active immunization against diphtheria should be carried out first of all by the private physicians in the different homes where the majority of young children can be reached. In large cities the milk stations, day nur series, children's dispensary, infant and orphan asylums furnish large groups of children suitable for immunization. The children of preschool age found in kindergartens and those of school age should be actively immunized. The success of such a procedure depends upon the development of a public health conscience in the people of the country. Zingher1 believes that the diphtheria problem seems nearer a solu tion by the thorough application of these newer diagnostic and im munizing procedures which should be encouraged by the various departments of health. On the other hand, J. G. Cumming, writing on the question, " Is the control of diphtheria leading to eradication?" in the Journal of the American Medical Association for March 4, 1922, states that the present procedures for the control of diphtheria do not seem to be leading toward the complete eradication of the disease, since the case rate is approximately the same as that of 30 years ago. By eradication he means such perfect control of the factors concerned in diphtheria that epidemic spread of the disease becomes impossible. The factors underlying present-day procedures for the control of diphtheria are: (1) Early clinical and laboratory diagnosis of the disease and the isolation of the patient; (2) laboratory identifica- 1Collected Studies from the Bureau of Laboratories, City of New York, vol. 9. 640—22 7 470 Vol. XVII. EDITOKIAL. tion of the healthy carrier and his isolation; (3) the Schick test and immunization ; and (4) the use of antitoxin as a curative measure. Only the first two of these factors are useful in the prevention of infection distribution ; the other two are of value in the reduction of mortality. The correct diagnosis, followed by quarantine of the patient and of the carrier, has for about a quarter of a century been the accepted procedure for the prevention of distribution, yet we still have epi demics, and the few deaths in each endemic and epidemic focus throughout the United States amount to an annual toll of more than 15,000 lives. So Doctor Cumming asks the questions : " Is not the gradual accumulation during the interepidemic times of unrecog nized carriers associated with oncoming susceptibles responsible for our periodic epidemics? Can such interepidemic carriers be pre vented by the activities of health departments, or is it a question of educating the people relative to the major avenues of disease dis tribution?" There seems to be no argument as to the value of the Schick test and immunization for morbidity and mortality reduction, but. asks Doctor Cumming, " Is it useful in the control of distribution ? " The injection of the antitoxin for the cure of the disease does not relieve the patient from the carrier state, and presumably the immunization by the injection of toxin-antitoxin mixture has no effect on the car rier state. If this immunization neither eliminates nor prevents the carrier state, and at the same time removes the danger signal (the manifestation of symptoms in those who have become infected as a result of transmission), there is developed a false sense of security— security against immediate mortality, but not against an increasing healthy carrier rate. If the control of diphtheria through the Schick test alone is to become as perfect in the prevention of diphtheria mortality as has the procedure for the prevention of typhoid fever, it will be necessary that 31,000,000 children now living be immunized and that 2,000,000 born each successive year be immunized. " Presumably," says Doc tor Cumming, " the accomplishment of this is not possible, and if it were, since there is neither elimination nor a reduction of carriers, is it worth while ? " As the four factors mentioned above have not proven adequate to eliminate diphtheria, resource must be made to a fifth factor —that of transmission prevention. The case rate can only be reduced by the blocking of transmission from the mild, unrecognized case and from the unidentified carrier. A reduction in the endemic carrier index seems to be the end desired. The epidemiologists must determine the avenues of distribution and devise practical methods for blocking them. "Only when these No. 3. 471 EDITORIAL. methods are inculcated into the habits and customs of the people will there appear a reduction in the endemic index, and the successful control of diphtheria leading to eradication." In a paper on the "Application of bacteriological studies to the prevention of diphtheria," read at a meeting of the Society of Medical Officers of Health held in London on • February 17, 1922, Sir Frederick W. Andrews considered the means at the disposal of public health officials in combating the disease. To him mere sanitation appeared to offer no solution to the diphtheria problem, the propor tion of immunes being actually least in those individuals higher in the social scale. At present the means at our disposal are inadequate for the discovery of virulent carriers in the community as a whole, for their isolation, and for the cure of the condition in all cases. It seemed to him that the problem of the undiagnosed case called for better education both of the public and the doctor. "From the point of view of prevention by immunization rather than by the prevention of the spread of infection we now have an effective method, so far as concerned the individual, in the injection of toxin-antitoxin. Up to the level of the institution the problem of the prevention of diphtheria was solved if we chose to use the means at our command, but this was not true in dealing with the com munity as a whole. Prevention by the removal of infection only might defeat itself by the production of a population having no resistance to diphtheria. The method of active immunization would involve the Schick testing of young children and injection of the positives. The immunity conferred is found to be fairly lasting and probably persisted after antitoxin had disappeared from the blood, the earliest stimulus of a commencing infection reawakening the dormant machinery of antitoxin." Sir Frederick set forth an inter esting speculation " whether, if the whole community were made immune, the bacillus, condemned to an existence of helpless sapro- phytism, might not degenerate into a relatively7 harmless atoxic form." Writing on "Active immunization with diphtheria toxin-anti toxic " in the Journal of the American Medical Association for March 11, 1922, Dr. Jacob Meyer, of Chicago, states that in 108 children the duration of immunity conferred by injection of diphtheria toxin- antitoxin mixture as determined by the Schick test extended for a period of 44 months in 94.4 per cent of the cases. In Chicago the incidence of diphtheria has decidedly diminished since injection of diphtheria toxin-antitoxin was adopted as a rou tine measure. This coincides with the experience in New York, where the efforts of the department of health to immunize the school children have been so successful as to prompt the State board of health to immunize children throughout the State, cw. m. k.) 472 Vol. XVII. EDITORIAL. ON SYSTEMIC INFECTION DUE TO ORAL SEPSIS. It Avas as recently as 1911 that Dr. William Hunter, of London, first brought to international attention in such a forcible manner his com- demnation of certain methods of dentistry, as then practiced, which observation and investigation had convinced him so frequently re sulted in pathology of the oral tissues or oral sepsis. While Doctor Hunter's observations lead to an awakening of the medical and dental professions, his work, as well as that of many others, was not based upon scientific evidence. Dr. C. E. Bentley, writing in the Illinois Medical Journal for February, 1922, on systemic infections due to oral sepsis says : " The work of Doctor Hunter and many others could be summed up by saying that clinically they noted the improve ment which followed the extraction of teeth in hundreds of cases." Incidentally it also might be stated that hundreds of cases showed no clinical improvements as the result of extraction of teeth. That serious systemic infections occur as a result of suppurations in the mouth is a view which, starting as a small wave of progress, has increased to overwhelming dimensions as is shown by many nota ble papers and laboratory experiments in recent years. Bentley cites the laboratory experiments of Bosenow, demonstrat ing the selective affinity of organisms, and of which he remarks: " These experiments seem to have established beyond question the im portance of the blood stream as a carrier of infection and also the very peculiar and as yet unexplained tendency for the organisms to have what might be termed a selective affinity for the same tissues in ani mals as in the individuals from whom cultures were obtained." Ex periments in animal inoculations have opened new fields of investiga tion, the exploration of which are becoming of particular value in reference to diagnosis. Chronic arthritis, endocarditis, nephritis, cholecystitis, ulcers of the stomach, and appendicitis are given as the most frequent definite secondary effects to oral foci of infection, " while general impairment of health and vigor, with or without recognizable lesions, is common." In regard to arthritis, attention is invited to the fact that in young persons, say up to 20 years of age, the condition is due to secondary infection of the tonsils, adenoid tissue, or infections of the paranasal sinuses and not to oral infection, but in middle and later life very few cases are due to these causes ; arthritis then being largely due to periapical infections of the teeth. Early dental diagnosis is desirable and imperative if preventive medicine is the aim, as the progress of the disease tends to metastatic infection of the joints, manifestly a much more difficult situation to meet than the eradication of the primary periapical infections of the teeth. Endocarditis, like arthritis, is due to infection, and its most dangerous symptoms are shown in the old patient and not in the No. 3. 473 EDITORIAL. young. Doctor Barker, of Johns Hopkins, says : " It is not at all uncommon to have viridans endocarditis arising from infected teeth. I have personally observed over 20 cases, and every one of the patients is dead." It was possible for Doctor Barker to demonstrate, in several of these patients, the presence of Streptococcus virklam in granulomata in the mouth. To quote Doctor Barker further, "The method of procedure at Johns Hopkins Hospital is to study the mouth in all cases of arterio sclerosis and of arterial hypertension in order to detect there any source of infection that may signify danger. They do that not only in the cases here mentioned, but in every patient who comes for diagnostic study. Suspicious gums are carefully examined and every pulpless tooth is X-rayed. A report from an expert dental diagnos tician is considered, with other accumulated data, before the final diagnosis is made." Due to the natural vigorous resistance of the oral tissues, the pres ence of chronic foci does not indicate by any means that an in dividual is suffering from systemic effects, but it does indicate a con stantly lurking danger. A most important point in this connection is that the development of definite lesions from these foci is so gradual that they are generally not recognized by the patient, consequently a physician is not consulted until the disease has made such progress as to offer obstinate resistance to treatment and in many cases to be incurable. The opportunity for the dental profession exists, first, of course, in periodical dental prophylaxis as a preventive to the development of oral pathological conditions and, second, in the early recognition of dental foci of infection before the patient is aware of the existing conditions, or the appearance of symptoms indicative of secondary lesions. In viewing foci of infection the all-important fact must not be over looked that these embrace many sources from which similar infec tions and results may come, prominent among these being the tonsils, paranasal sinuses, gall duct, intestines, Fallopian tubes in the female, prostate gland in the male: in short, wherever in the body the condi tions are favorable for the growth and distribution of pathogenic organisms. The practice of extracting all nonvital teeth, recommended by some physicians, is in the light of results obtained by skillful conservative dentists being abandoned by the leaders in both professions. The conservative dentist pleads for the retention of inadequately filled pulp chambers about which no rarefied areas are shown by the X ray, but always with the reservation that they be constantly watched for untoward symptoms. 474 Vol. XVII. EDITORIAL. In connection with accessory foramina remaining unfilled by vir tue of size and inaccessibility, Bentley, in common with others in vestigating this condition, believes that they should be given the benefit of the doubt in view of the evidence tending to the conclusion that their contents, under favorable conditions, become organized and their openings finally covered with omentum, thereby prevent ing infection at these points. Dental diagnosis should always be based upon clinical examination, as well as X-ray findings, and in general the internist, the dentist, and radiographer should be in consultation. To Dr. Frank Billings we are indebted for the following state ment: "To investigate and manage these patients requires the team work of the clinical and laboratory workers. The clinician must carefully examine the patient, exhausting every detail in personal history. The skill of the dentist, the nose and throat specialist, the gynecologist, the genito-urinary expert, and others may be neces sary to locate the foci of infection. Each focus must be destroyed." Bentley agrees in principle with many when he states in his paper: " It can not be too strongly said that a tooth which can not be made healthy should be extracted, but all of us who have looked into this matter know that many teeth to-day are being cast out when they could be made things of use and beauty by modern methods of treatment." In reference to the subject of systemic infection due to oral sepsis, it might be of interest to quote Doctor Gardner, of the Mayo clinic : "We have come to the conclusion some time ago that all teeth showing definite pathology should be sacrificed," which is a positive statement from a recognized medical center and indicates the value placed upon dental diagnosis, (h. e. h.) HAND INJURIES. During the calendar year 1920 injuries of the hand and fingers caused 27.G89 sick days in the Navy, and 18 men were invalided from the service in consequence of such injuries. Proper management of these cases is one of the most difficult problems that the naval medical officer is called upon to solve. The responsibility is great, not only to the patient, because good func tion is necessary to enable him to earn his living, but also to the Government, because sick days with full pay and lifelong compen sation for disability are tremendously expensive. The first treatment is most important and is never to be slighted for minor injuries may develop into severe infections, tenosynovitis, or ankylosis if they are not properly treated. Tetanus is a danger No. 8. 475 EDITORIAL. that must be always in mind, especially in the motorcycle accidents which are now so prevalent. Conservation of all possible tissue is an excellent rule, for one is frequently surprised by the recuperative ability of tissues apparently without circulation. Accurate adjustment of fractures is essential because thus the smallest amount of callus is produced. Excessive callus leads to involvement of the tendons and their sheaths, with ankylosis as a result. To avoid ankylosis early massage and manipulation are im portant. Manipulation begun too early produces nonunion; if de layed too long ankylosis results. Experience and frequent X-ray examinations are necessary to determine when to start manipulation. If infection occurs the first incision should be radical in order to avoid the necessity of repeating it later. There is no place where the Carrell-Dakin technique produces more strikingly beneficial re sults than in the infections of the hand or fingers. Proper prepara tion of the wound so as to allow access of the solution to every part is essential. Willems has taught us the importance of open treat ment and frequent motion in infected joints, and these principles are of equal importance when the tendons of the hand are the seat of infection. Reconstructive surgery of the hand is one of the most difficult, delicate, and uncertain branches of the surgical art. The necessity for it will be lessened by proper care of injuries in their early stages. Careful checking of the diagnoses made by experienced men against the X-ray picture shows almost 50 per cent of failure in diagnosis of fractures of the bones of the hand without the use of the X ray. This difficulty of diagnosis and the serious results of failure to make the proper diagnosis make the serious injuries of the hand or fingers essentially hospital cases. n glands and teeth, but that evening he had a sudden sharp pain in the great toe of the left foot, which he said he had " stubbed " a few days previously. Examination showed only slight blackish dis 496 Vol. XVII. CLINICAL NOTES. coloration of the nail. An hour later the pain in the toe was ex cruciating and the discoloration was found to extend up in a wedge- shaped area over the dorsum of foot to the ankle. This area was mottled red, involving almost the entire dorsum of the foot and great toe. Hot fomentations furnished some relief. Early the next morning the patient had a sudden severe pain in the chest (substernal) without cough, but accompanied by dyspnoea, marked cyanosis, and very feeble rapid pulse. The area of discol oration, as above noted, was found to be sharply defined, wedge- shaped, apex upward at ankle, and blue-black in appearance. The lungs showed beginning edema, which accumulated rapidly, with death resulting at 9.05 a. m., the patient remaining conscious to the end. Autopsy showed embolism of the anterior tibial artery at left ankle, pericardial exudate, thrombus filling entire right ventricle, and edema of the lungs. The gall bladder was markedly dilated. The liver, kidneys, spleen, stomach, and intestines showed no macro scopic lesions. Owing to the lack of facilities, no pathologic sec tions were made. The mercurial injection consisted of 1 grain of the salicylate in oil injected deeply into the buttock. The medical officer reported that on both occasions the syringe was removed from the needle and the latter inspected for bleeding. There was no sign of a vessel having been punctured in either case. No incision was made at the site to determine the amount of absorption. It is interesting to note that the deceased was one of several who received mercury on the respective days. He was second of four on the first occasion, and third of four on the second and last. None of the others so injected had reactions of any sort. A CASE OF EPIDEMIC ENCEPHALITIS.' Patient : L. C. U., seaman, United States Navy. —Encephalitis, epi demic (lethargic). Previous history.—Patient 20 years old ; had been in naval service since February, 1917. His family history is negative, his father be ing a coal miner and the patient himself having worked at times in the coal mines. On December 19, 1919. patient had lobar pneu monia in lower left lobe. He was sick at that time until July 15. 1920, the pneumonia being very slow in resolving. Tuberculosis was strongly suspected, but no definite signs of this could be found. His sputum was examined nearly every day from February to July, 1920, 1 From the Annual Sanitary Report of the United States Naval Hospital, Portsmouth, N. H. No. 3. 497 CLINICAL NOTES. and no tubercle bacilli were found. On July 15, 1920, he left the hospital after a month's sick leave in apparently good condition. On December 27, 1920, he was readmitted with bronchitis, acute, and on January 14, 1921, tubercle bacilli were found in the sputum and the diagnosis changed to tuberculosis, chronic pulmonary. From that time on tubercle bacilli have been found in his sputum at frequent intervals. X rays of his chest show areas of consolidation in his left lower lobe. Subsequent illness.—Patient was admitted to this hospital Decem ber 27, 1920, with a diagnosis of bronchitis acute, this proving on January 14, 1921, to be tuberculosis, chronic pulmonary. On admis sion patient had temperature of 101° and complained of double vision, which he states he had had for previous week. Blood count at that time was 86,000 whites and 59 per cent polynuclears, haemo globin 82 per cent. His temperature varied between 100° and 102° on December 28 and between 99° and 100.4° on December 28, 1920. On December 30 he had an evening rise to 99° ; on December 31 it was normal all day; and on January 1, 1921, an evening rise to 99.5° occurred. From that time on his temperature was normal until Jan uary 18, 1921, when he had a midday rise to 100.8°. From then on the temperature stayed between 98° and 100° until January 28, from which time his temperature was normal. On December 31, 1920, it was noticed that his left pupil was smaller than his right, both being rather small and reacting poorly to light. On this day he complained of a slight frontal headache for the first time. A complete examination of his reflexes showed both knee jerks marked but equal, no ankle clonus and no Ehomberg. Blood examination showed 10,800 whites and 67 per cent poly nuclears, 5.100,000 reds and 90 per cent haemoglobin. At this time the patient began to develop a marked apathy, which daily increased. He would lie for hours without speaking and with closed eyes, but he was not sleeping, and upon being spoken to would answer. By January 18, 1921, this apathy had increased to such an extent that the patient was reported dangerously ill. This day also for the first time weakness of his facial muscles was definitely noticed, this being especially shown in his inability to show his teeth or smile or frown. He could, however, wrinkle his forehead. Wassermann, of January 13, was reported negative. On January 19 a spinal puncture was made and 15 cubic centimeters of perfectly clear fluid, flowing at the rate of two drops per second, was obtained. The laboratory reported that this fluid contained 37 cells per cubic millimeter, was positive for globulin, that no tubercle bacilli were found, and that the col loidal gold curve was 1-5-5-5-5-5-5. On January 23 blood had 5,800 whites, with 60 per cent polynuclears, 34 per cent mononuclears, and 16 per cent lymphocytes, 4,650,000 reds, and 80 per cent haemo 498 Vol. XVII. CLINICAL NOTES. globin. The apathy, which reached its height on January 18. con tinued unchanged until this date, the patient having incontinence of both urine and faeces, and never making the slightest movement unless urged. He was fed by a spoon by a hospital corpsman, liquid diet only being taken. On January 30 patient was observed to be a little brighter mentally. On February 3 he had improved sufficiently to answer questions, and said that his double vision had gone. His facial muscles also showed marked improvement, and he was able to show his teeth and smile. He improved rapidly from this time on and was up in a wheel chair for 20 minutes on February 19, and by February 25 he was up for 3 hours a day. In view of the fact that this patient had chronic pulmonary tuberculosis the diagnosis of en cephalitis, epidemic, was not made until all nervous symptoms had entirely disappeared, because of the danger of mistaking a possible tubercular meningitis for encephalitis, epidemic. He was seen by the entire staff from the first, and the opinion of all was that it was a case of encephalitis lethargica as early as January 30. but because of the presence of the tuberculosis in his illness the definite diagnosis was not made until March 22, 1921. The patient continued under treatment for chronic pulmonary tuberculosis and was transferred to the United States Naval Hospital, Fort Lyon, Colo., May 28, 1921, for further treatment. SPECIFIC TREATMENT OF PULP GANGRENE AND ITS SEQUELS. By F. S. Ticiiv, Lieutenant, Dental Corps. United Stutes Navy. When Dr. John Buckley gave the dental profession his " formo- cresol " (cresolis et liquoris formaldehydi, equal parts) for the treat ment of pulp gangrene and its sequelse, he gave a treatment which, from a rational therapeutic standpoint, is a specific. In fact, it is as much a specific for pulp gangrene as Ehrlich's salvarsan is for syphilis, or quinine is for malarial fevers. But alas, there often comes a patient who desires immediate relief from pain which is the result of a gangrenous pulp. We try to relieve the pain by opening into the pulp chamber and releas ing the pressure, but some of the liquids and gases of putrefaction have already been forced through the apical openings, setting up an acute septic pericementitis. It is then that a great number of us find ourselves in a dilemma. We try anodynes, local and general, anything to relieve congestion; saline cathartics, hot foot baths, ami what not, possibly the seemingly inevitable extraction and curettage. We know that if it were not for the irritating property of formo- cresol we would not hesitate a second to seal it in the most trouble some tooth, because we know the physiologic action of cresol — it acts So. 3. 499 CLINICAL NOTES. as an analgesic locally; it is a good disinfectant and cauterant. The other constituent of formo-cresol is liquor formaldehyde —a 37 per cent aqueous solution of formaldehyde gas—a powerful and highly irritating gas, which will readily combine with the fetid passes of putrefaction, and these form nonodorous compounds. It is a gas which one would hesitate to confine near a tissue which is already hyperemic. Doctor Buckley claims that the irritating effects of formaldehyde can be controlled by mixing it with cresol. This is true, but, on the other hand, I have found that the cresol-formalin combination as recommended by Doctor Buckley, very often proves to be highly irritating. As I have stated before, cresol acts as an anodyne, disinfectant, and cauterant. The ratio of each of these properties differ consider ably, and I take it that the disinfectant property exceeds by far the other two. We have an irritation set up by all disinfectants ; hence the pain set up by the disinfectant property of cresol is not offset by its anodyne property, and the result is that we have produced to some extent an irritation by the application of cresol. I will not discuss the formalin of the combination because its irritating prop erty is acknowledged by all. I agree with Doctor Buckley when he says that the irritating effects of formalin can be controlled by mix ing it with cresol. In my study of the two constituents of Buckley's treatment, I have found both to be irritants. The irritating effect of one (forma lin) is controlled by the other (cresol), but formalin has not a coun- tereffect upon the irritating property of cresol. To overcome this irritation I have used liquor cresolis compositus instead of the cresol. I have found that this compound solution of cresol has not the irritating property of cresol alone, and its action, when combined with formalin, in proportion of 3 to 1, is most admirable when sealed in the root canals of teeth with dead pulps. I believe that its action upon the ptomaines, fats, and fatty acids of pulp decomposition is not so violent, since the cresol of the com pound is predigested (if you please) by the potassium hydroxide of the compound. It is not so antagonistic (the cresol compound) in its neutralizing action, but still the action is there. So then we have the deodorizing and neutralizing effect of the formalin upon the gases, and its irritating property reduced to a minimum by the cresol of the compound, and the irritating property of cresol controlled by the potassium hydroxide of the compound solution of cresol. Along with the linseed oil of the compound plus the fats, fatty acids, and potassium hydroxide, we have an ideal cleansing solution — soft soap. The liquor cresolis compositus et liquor formaldehydi combination is an ideal remedy for cases in the naval service, be cause we have to treat not only patients that can present themselves 500 Vol. XVII. CLINICAL NOTES. for two or more sittings, but patients who are able to report for treatment only once. Then, too, I have experienced considerable trouble in having an ordinary combination of formalin and cresol made up at the dispensary (cresol will not mix with the aqueous formalin solution), whereas not so with the liquor cresol compound and formalin combination, since the latter two mix well and form a clear solution. The following is a good example of many similar cases, in all of which the action of the cresol compound and formalin combination proved to be superior to that of plain formo-cresol or modified formo- cresol : Patient, male, age about 42; physical condition good. Case pre sented two weeks ago. Suffered greatly from pain and lack of sleep. A considerable swelling in the apical area of right central incisor. Treatment (impossible to get radiograph) : Made opening through internal surface of crown of tooth, generous flow of thick greenish pus. Canal washed out and formo-cresol dressing inserted. Patient instructed to take a good " dose of salts." Boric acid solu tion compress to mouth and lip. Patient returned in a couple of hours suffering from acute septic pericementitis ; dressing removed and formo-cresol dressing replaced by combination of cresol compound and formalin. Next morning patient returned, very grateful, relieved of all pain; changed dress ing. After the sixth treatment the tooth had become firm in socket, canal clean and dry; followed treatment with strong root canal germicide, and filled with chloropercha plus thymol and root canal points. CATHETERIZATION OF WHARTON'S DUCT. By T. L. Sampsell, Lieutenant, Dental Corps, United States Navy. Although cysts in the floor of the mouth and ranulae of one kind or another are not frequently encountered in the practice of den tistry, yet, now and then, one is encountered when least expected and, unless promptly recognized and successfully treated, gives rise to disturbances of a severe character. Inspection of the literature on the subject shows that this ground has been fairly well covered, and its repetition would be superfluous here but for the fact that no authority which I have been able to consult thus far mentions that method of treatment which, in my opinion, is the simplest and most satisfactory for these conditions, i. e., the simple catheterization of the duct. To avoid encroaching upon that which has already been written, this report is confined to the actual treatment of three cases which No. S. 501 CLINICAL NOTES. occurred in my own practice, the last quite recently, all of which were clinically the same and treated alike. Upon examination in each case the caruncula sublingualis was seen to be engorged and pointing upward toward the elevated tongue in stead of lying parallel to it and flush with the floor of the mouth. The submaxillary gland was distended but did not pit on pressure and was slightly tender to the touch. The ducts of Stenson were occluded with cotton rolls to prevent their discharge of saliva during the examination, and the floor of the mouth was evacuated with the saliva ejector. The floor of the mouth was then swabbed dry, the tongue elevated, and the action of Wharton's ducts observed for several minutes. The duct on the unaffected side continued to discharge its saliva normally, while the floor of the mouth on the affected side remained dry. A strand of ligature wire, thin gauge, was bent double, leaving a very small loop at the end which would distend but not injure the duct. The loop was then passed through the meatus into the duct and gently maneuvered backward into the gland, the fingers of the left hand manipulating the floor of the mouth from outside and be low, thus assisting in overcoming the duct curvatures. The gland in each instance began to empty itself immediately, and numerous small bits of caseous material could be observed in the dis charged saliva. In two or three minutes the duct appeared to be functioning normally, and the wire was withdrawn. The patient was then instructed to massage the gland from time to time, chew gum, and exercise the neck muscles periodically until the condition had completely subsided. This usually occurs in a few days, but the patient should be observed for a week or two longer for a recurrence of'the obstruction. The writer firmly believes that this method of catheterizing the duct is the specific treatment for all simple duct obstructions and, in all cases, should precede any decision to intervene surgically. No especial skill is required in catheterizing the duct, though great care should be taken not to injure the walls. 646—22 9 NOTES AND COMMENTS. The death of Charles Louis Alfonse Laveran at the age of 76, on May 18, following so closely that of Sir Patrick Manson. removes another of the great pioneers of tropical medicine. Laveran was the actual discoverer of the malarial parasite of man, and both he and Manson conjectured that the mosquito would be found to play a part in its transmission, a theory which obtained final proof from the researches of Ross in India, and Grassi, Bignami, and Bastianelli in Italy. Laveran's researches covered a wide field in the realms of parasitology. He was an indefatigable writer, and a complete list of his publications would cover many pages. The following sketch of his life appeared in the Lancet for May 27,1922: Alfonse Laveran was born on June 18, 1845. He commenced his medical studies at the civil hospital in Strasburg, where he graduated doctor of medicine in 1867, with a thesis entitled " Recherehes experimentales sur la regeneration des nerfs." In 1874 he was appointed to the staff of Val-de-Grace School of Military Medicine in Paris. He served in north Africa from 1878 to 1883, and there conducted the researches on malaria which have made his name famous. Returning to France in 1884 he occupied the chairs of military hygiene and clinical medicine at Val-de-Grfl.ce for 10 years. For a short period after this he held the post of medecin chef of the HOpital Militaire at Lille and director of the Service de Sante at Nantes, and during this period his brilliant observa tions on the parasite of malaria received confirmation at the hands of Italian workers. Honors commenced to shower upon him. He became a member of the Academie de MMecine in 1893, and member of the Academle des Sciences In 1895, while various other medical and scientific bodies felt it an honor to include him on their roll of fellows. He was elected an honorary Fellow of the Imperial Military Academy of Medicine of St. Petersburg, a foreign member of the Royal Society of London, a Fellow of the Medical and Chirurglcal Society, and hon orary Fellow of the Royal Society of Tropical Medicine and Hygiene. In 1889 the Academle des Sciences awarded him the Breaut prize and the Cothenius gold medal. In 1905 he was awarded the Mary Kingsley medal by the Liverpool School of Tropical Medicine. He became a " meclectn principal " of the army, an officer of the Legion of Honor, and was universally recognized as the highest authority on military hygiene and sanitation. There was opening up before him a public career of such brilliance that it would have attracted many a man of high scientific attainments. But not so Laveran. His early experience of microscopic investigation had so fascinated him that he longed for the quiet and seclusion of a laboratory where he could pursue his studies without interruption. Accordingly, in 1897, he suddenly 603 504 Vol. XVII. NOTES AND COMMENTS. abandoned his public career and retired to the Pasteur Institute of Paris, where lie became professor, and. finding the atmosphere congenial, remained constantly for the next 25 years. His interest in malaria was first aroused in 1878 by the characteristic malarial pigment in the liver and brain of fatal cases. This pig ment, of course, had been previously noticed, bur it was Laveran who observed the same granules of pigment in the blood inclosed In crescent-shaped bodies or In spherical structures which exhibited amoeboid movements. He regarded these bodies as parasites, but was not absolutely convinced till 1880. when at Constantine he observed for the first time the striking phenomenon known as flagellation of the crescents. His views were received with doubt in many quarters, but with that doggedness and determination which characterized all his subsequent work he remained true to his beliefs, which were finally recog nized in 1889 by the Aead&mie des Sciences, and in 1907 by the award of 111•■ Nobel prize for medicine, which lie devoted to the establishment of laboratories of protozoology at the Pasteur Institute. In the same year he was elected firs president of the Soeietf- Pathologie Exotique of Paris. At the Pasteur Institute Laveran devoted himself to the study of protozoal parasites, especially those forms which occur in the blood and are pathogenic to man and animals. The discoveries of trypanosomes as the cause of nagiina by Bruce and his coworkers in Zululand in 1890, and by Dutton in man in the Gambia in 1902, attracted his attention, with the result that he undertook the study of these organisms chiefly in collaboration with his colleague. Professor Mesnil. He carried out a long series of most intricate researches into the behavior of these organisms in experimental animals, in the hope of discovering a remedy for the dreaded sleeping sickness of Africa. With the discovery of leishmania as a cause of disease in man, Laveran undertook the study of these organisms, and has published the most complete account of the diseases they produce that has yet appeared. Laveran was an acute observer and had absolute confidence in his own observations anil opinions, to which he adhered with almost stubborn persistence. For example, most authorities now believe that there are three species of malarial parasite producing disease in man, but Laveran adhered to his original view that the variations observed were an indication of the polymorphism of the single species. Again, he devised an immunity test for the separation of trypanosomes, and concluded that any trypanosome which could be inoculated into a goat or other animal which had acquired an immunity to another trypanosome was a distinct species. Though the criterion is not generally accepted, Laveran main tained his opinion that it afforded a reliable means for distinguishing species Since the views to which he clung so tenaciously were no mere dogmatic asser tions, but were the outcome of personal observations, extending over many years, one could not but admire his refusal to relinquish them readily. Those who have had the privilege of knowing Professor Laveran personally can well understand the admiration and respect with which this great man was regarded. Those who did not know him would find it hard to realize how complete was his absorption in his work. Prom 8 a. m. till 8 p. m.. with only the usual break for dejeuner, he was to be found in his laboratory on six days in the week. Sunday afternoon alone was spent in recreation, which consisted frequently in reading at home or planning future researches. Laveran objected to interruptions in his work, not because of any harshness of tempera men t, but because he was reluctant to lose a moment of time. He was, however, always ready to listen to anyone who had serious matters to discuss, though he found it irksome to converse except in French. He found time to publish many comprehensive treatises. While in 1867 he wrote on the regeneration of nerves, in 1873 he published a treatise on tuberculosis. In 1875 appeared the Traite No. 3. 505 NOTES AND COMMENTS. des Maladies et fcpidemies ties Armies, while in 1880 he published in the Pro ceedings of the Academy of Science his famous paper entitled " Note sur un Xouveau Parasite Trouvl dans le Sang de Plusieurs Malades Atteints de Fievre I'alustre." His observations on malaria appeared in book form in 1884 as the TraitC de Fievres Palustres, in 1891 as Du Taludlsme et de son Hfmntozoaire. and in 1898 as his Traite de Paludisme, a new edition of which was issued in 1907. In 1894, in collaboration with Teissier, he published a book entitled "Xouveau Elements de Pathologie Medicale," and in 1904 appeared the well- known Trypanosonies et Trypanosomiases, written in collaboration with Pro fessor Mesnil. A new edition of this book, which had been translated into English, appeared in 1912, while in 1917 he reviewed the whole subject of kala-azar, oriental sore, and allied diseases in his work entitled " Leish maniases." These form but a small part of the numerous papers issued by this remark able worker, and almost everything he wrote was a practical record of facts observed by himself. Herein lies the immense value of his work. He was a man of iron constitution, stupendous energy, and quite unusual powers of mental application. Combined with these characteristics he had the true scientific mind, which entitles him to be remembered as one of the great leaders of scientific research. We learn from the British Medical Journal for May 27, 1922, that (he seventh centenary of the University of Padua was celebrated on May 14 to 17 in fortunate circumstances. The weather was fine, Imt not too hot, and over 200 foreign delegates attended, about 50 coming from the United States of America, about 30 from Great Britain, Ireland, and the Dominions, and a large number from the universities of Italy. On Sunday, May 14, the delegates met in the grand hall of the university at 2 p. m., under the presidency of the rettore magnifico, Prof. Luigi Lucatello; this preliminary ceremony was followed by a discussion on " Scientific synthesis and speculative science, the methods and aims of these researches, and their relation to philosophy." During the day the students organized a pictur esque carnival and paraded the streets, as they did on the following Tuesday; in the evening there was a reception at the Casino Pe- drocchi. Monday, May 15, was the chief day of the centenary, as the King of Italy arrived and presided at the solemn ceremony in the Sala Ragione, where, before an audience of 5,000 people, addresses were delivered by the rettore magnifico. the sindaco. and Prof. Nino Tamassia, and the students sang verses by Giovanni Bektacchi, set to music by Riccardo Zandonai. The foreign delegates and those from other universities and bodies in Italy handed in their congratu latory addresses, and short speeches were delivered by one repre sentative of each of the nations. The British representative was Sir Archibald Garrod, an appropriate choice, for not only is he regius professor of medicine in Oxford— the oldest British university — but in that capacity a prominent figure in the subject matter of one of 506 Vol. XVII. NOTES AND COMMENTS. the chief faculties of the University of Padua, with which the hon ored names of Linacre, Caius, and Harvey are so closely connected. In the evening there was a gala performance of Arrigo Boito's Mefistofele, which was attended by the King of Italy. On Tuesday morning Prof. Augusto Bonome delivered -an oration on Morgagni. and a large number of honorary degrees were conferred on the repre sentatives of foreign universities, including those of this country, who were well represented in the list and most cordially received. This was followed by a visit to the Collegio Sacra, where more ad dresses were delivered: the company then made a special train journey to an open-air lunch in the beautiful grounds of the Istitnto Idrotechnico (Villa Keale) ; in the evening a banquet was given to the' delegates by the municipality of Padua. Wednesday. May 17, the last day of the celebration, was occupied by an excursion to Venice. The town of Padua was en fete and provided much of interest for the visitors, who were able to study the stemma of Wil liam Harvey in the court of the university. Admiral Braisted, writing in The Nation's Health on the Gorgas Memorial Institute to be established at Panama, pays, indeed, a glow ing tribute to the late master of tropical sanitation. Gen. William C. Gorgas, United States Army. " Formerly men memorialized their heroes in stone, with the result that the monuments of the world are for the most part retrospective, representing some peak of past achievement, but exerting no vital force of inspiration or restraint except as they are reinterpreted by successive generations. And yet. if civilization is to carry on, it is through uninterrupted cumulative achievement; and the most enduring memorial to any man is the provision of the means by which to perpetuate his work. Especially when a humanitarian achievement has been made possible by the unusual skill or the clear vision of one man does such perpetuation seem desirable. As this applies to the work of General Gorgas, he may well be considered as the personification of the public health era and the plant of the Gorgas Memorial Institute in Panama a truly representative enterprise. Established in a country unhappily known as the pesthole of the Tropics, which, by his efforts, was trans formed into one of the healthiest places on the face of the globe, the institute will afford opportunities complete in every detail for trained research men a*nd scientists from all over the world to work together upon the common problem of how best to prevent and eradicate dis ease. " Anyone who has seen the old Panama at the time of the abandon ment of the work of the first canal, involving so much wasted energy, life, and money, with its abandoned equipment and the evidences of No. 3. 507 NOTES AND COMMENTS. unsuccessful labor, and the thousands of unknown and unnumbered graves of its workers, can not help but be struck with the present aspect of Panama, its splendid sanitation, its beautiful cities, its fine hospitals, and the magnificent accomplishment of the completion of the work of the canal, making it one of the most beautiful and salu brious spots in the world. " The accomplishment of this great work and the sanitary regenera tion of Panama are due to the efforts of the late William C. Gorgas, United States Army. To his efforts more than to any other agency the success of this work must be accredited. His earlier work in the Southern States and the West Indies, particularly Cuba, his later efforts in Ecuador and Peru, and his projected work in Africa, give one an idea of the vast field of splendid endeavor which he accom plished and would have continued had his life been prolonged. His reputation has gone forth to all the world, and he is loved and re vered in every household. Perhaps no single life has ever made pos sible so much for the good and wellbeing of humanity as has that of General Gorgas. "Many types of memorials were considered to do honor to this great man, but I feel sure that the establishment of this memorial, the Institute for Research in Tropical Diseases and the Study of Pre ventive Medicine, carrying with it not only a permanent monument to his memory, but one that will continue his work and be of greatest value to the welfare of the entire world, will be considered the ideal commemorative effort. Panama, situated in the heart of the Tropics and in the midst of the Central and South American States, which offer a splendid field of work of this kind, would seem to be the ideal location, furnishing a wealth of material for the institution which is brought into existence." Prof. J. J. Van Loghem, director of the department of tropical hygiene at the Colonial Institute, Amsterdam, delivered a lecture to London recently, on the "Transmission of plague by rats." We learn from the British Medical Journal that in the lecture he dealt with the plague question as it affected Europe past and present. He confined himself to bubonic plague, which he regarded as being the plague of all the great historical epidemics, and his argu ment was that in the time of old Europe the domestic architecture, the habits of the people, and the sanitary conditions generally were such as to encourage the breeding of rats in much closer proximity to man than was the case anywhere in western Europe to-day. At the time of the plague outbreaks in London and Amsterdam in the seventeenth century the rat probably lived as near to the occupiers of dwelling houses as it did at the present time in the plague-stricken areas of the Tropics and sub-Tropics. In this connection he spoke 508 Vol. XVII. NOTES AND COMMENTS. of his recent investigations in Java, where he found the house rat— Mm rattus—making its nest inside the bamboo poles used for the beams of the houses and the supports of the beds. Plague infection, in his view, depended upon the distance between rat and man being sufficiently short to permit of the rat flea conveying the disease to man. The influence of climate and season upon the rat flea carrying the plague parasite accounted for the climatic and seasonal variations of rat-borne plague. He showed diagrams illustrating the fluctua tions of the plague in London and in certain Dutch towns in the seventeenth century. In all these cases the highest point was reached in August and September, after which there was a sharp decline. He quoted Daniel Defoe's Journal to prove that in the winter and spring preceding the plague of 1665 in London isolated cases appeared within a few weeks of each other and traceable to the same neighbor hood —Long Acre —although it was not until the summer that any epidemic arose. There was no difficulty in explaining these sporadic cases in the light of modern knowledge if it was remembered that the propagation of the plague depended not on contact between human beings but on the activity of the rat flea, for the supposition was that all through this epidemic-free period there was plague among the rats, and only when the seasonal conditions favored insect activity did the epidemic arise among human beings. His pupil. Doctor Dykstra, of Amsterdam, had made some interesting re searches on the plague which occurred in that city is 1617. by study ing the lists of the Carthusian burial ground. They gave full par ticulars of the persons interred, including their places of residence, and he found that for six weeks in the early summer the plague was strictly localized to two or three streets ; later it spread over a large quarter of the town, but its spread was topographical, from house to house and street to street. There was no other explanation of such a picture than localized rat plague. The animal concerned was not the brown or gray rat now familiar, but the black house rat. the "big mouse." which was rarely seen in Europe to-day. Even in the time of Cuvier the black rat, though still common, was being ousted by the brown, but it was a rat of the same species as this former domes ticated habitant of Europe which caused the recent outbreak of plague in Java. That the brown rat can carry plague in the same way is, of course, evident ; it was the brown rat which was responsible for the small epidemic in Paris in 1920, when most of the 150 victims were rag dealers, who were compelled by their trade to live near to the haunts of the rats; but the point is that the brown rat is not a domesticated animal like its predecessor, and to that extent is less dangerous. In the old days, with dark house interiors, straw beds, and abundance of food and other stores kept in dwellings, the black rat had a fertile breeding ground. Xo. 3. 509 NOTES AND COMMENTS. We learn from the division of venereal diseases of the United States Public Health Service that G. Stura offers a modification of Fontana's method for the demonstration of Treponema pallidum. The modification concerns the staining stage of Fontana's method and should be carried out as follows: (1) Smears fixed by heat are kept for a few minutes in a solution consisting of formalin 50 cubic centimeters, acetic acid 2 cubic centimeters, distilled water 150 cubic centimeters. (2) After washing with distilled water pour on the slide a few drops of a mixture of 5 grains of tannic acid, 3 grains of carbolic acid, and 100 cubic centimeters of distilled water. Warm on a flame up to boiling point. (3) Wash repeatedly. Pour on the slide pure ammonia; after a few seconds pour it off and. without washing, allow a 0.5 per cent solution of AgNO, to pass from one side of the slide over the smear. As soon as this has become brown the staining is finished and there only remains washing the prepara tion and drying it over a flame. Recent medical literature contains many expressions of opinion by syphilographers of this and other countries regarding the high incidence and earl}' onset of neurosyphilis. Another condition cited by them is that an increasing number of patients in the infectious second stage are being observed in the clinics. Many of the writers claim that too rapid sterilization and inadequate treatment are re garded as important contributory factors. Because of the serious ness of the problem and the diversity of opinion regarding the cause, the United States Public Health Service recently addressed a com munication to a few of the leading syphilographers of this country asking for an expression of opinion on this important subject. The general opinion of the men written to is expressed as follows : While a certain amount of the apparent Increase of neurosyphilis is due to the increasing use of spinal fluid examinations and other modern diagnosis methods, I think there is no question that the ineffective use of arsenicals plays a very important part in this most undesirable tendency * * * the physician or health officer who is unable or unwilling to follow a syphilitic patient through a period of years, if not for life, should not attempt to treat the disease. Relapse is certainly the great outstanding fact of syphilis, and the so-called modern treatment has certainly not entirely done away with it. In particular, relapse in the nervous system and infectious involvement of the mucous membranes and genitalia are so alarmingly frequent under the in adequate use of arsphenamine that every agency which employs this drug in the treatment of syphilis should be thoroughly on the alert and equipped to detect the earliest manifestations of relapse. (Stokes.) It appears to us that among the factors mentioned as probable causes two are of paramount importance, viz, (1) the tendency to undertreat; (2) the fail ure to interpret pathologic findings in the light of the clinical picture. (Fraser 510 Vol. XVII. NOTES AND COMMENTS. and Duncan, British Journal of Dermatology and Syphilis, July, August, and September, 1921.) To these we would add another of almost equal impor tance— the tendency to interrupt treatment by periods of rest. To our minds the treatment of all syphilis ought logically to be continuous rather than inter mittent. Early neurosyphilis In the form of neurorecurrences would be re duced to nil if this were done. Late clinical neurosyphilis might be equally easily avoided by the early routine use of spinal puncture and by adjustment of treatment to the pathological findings. We agree that the "sterilization" treatment of syphilis, as exemplified by Pollitzer's method, is distinctly dan gerous from the point of view of neurosyphilis, and that treatment should be directed toward building up the patient's own resistance to the disease. Stokes's discussion of this problem in his paper, " The application and limita tion of the arsphenamine in therapeutics" (Archives of Dermatology and Syphilology, September, 1920; see Venereal Disease Division Abstracts, March, 1921) deserves wider circulation than it has as yet obtained. The most crying present need of syphilotherapy is a standard treatment, sufficiently elastic to be adapted to all types of cases and sufficiently simple to be used by the aver age physician « * * unless a physician feels himself competent to carry out all the necessary procedures in the treatment of any given case, he should not attempt to treat it at all. Though many cases can be successfully dealt with by the general practitioner, he should realize that the appearance of any complicating features is sufficient to warrant the transfer of the patient to a competent syphilologist. (Keidel and Moore.) Syphilis of the nervous system probably begins in the first year of the infection. The number of cases corresponds roughly with the total number of cases of so-called late neurosyphilis. These statements are based on the fol lowing observations : (a) The number of early cases showing positive findings in the spinal fluid; (b) l'nmilial types of neurosyphilis; (e) biologic evidence of a neurotropic strain of the treponema ; (d) persistence of the Infection in loco, as in aortitis, interstitial keratitis, etc.; (e) observation of patients who developed signs of early syphilis of the nervous system and who after many years died of paresis or other late degenerations ; (/) no serologic evidence as yet exists showing normal spinal fluid in the early stage and its infection at a later period. Early neurosyphilis may manifest itself by obtrusive symptoms, by slight objective signs, or be asymptomatic. Unless they are properly and thoroughly treated these early infections may persist and cause late neurosyphilis. Every case of early syphilis should be treated intensively with arsphenamine and mercury given systematically in courses consisting of not less than eight injections of arsphenamine or its equivalent, neoarsphenamine or silver arsphe namine, and 15 injections of mercury; a minimum of two courses of the for mer and three of the latter should be administered. The treatment should be controlled by frequent Wassermann tests and a lumbar puncture made about six months after infection or earlier if indications should exist. Complete neurological examination should be made in order to detect early involvement of the nervous system and as a control for future examinations. The treatment outlined is not an insurance against the occurrence of neuro syphilis, which not infrequently takes place during the active administration of the drugs. In such cases intraspinal medication administered by one familiar with the proper technic may be a necessary adjunct. It is only by controlling early neurosyphilis that we can hope to prevent the later degenerations. (John A. Fordyce.) No. 3. 511 NOTES AND COMMENTS. In commenting on these opinions Asst. Surg. Gen. C. C. Pierce. United States Public Health Service, says : " It is of extreme importance, therefore, that physicians engaged in the treatment of syphilis carefully consider these statements and direct treatment toward the avoidance of the dangers outlined. "In inviting your attention to this matter the service is not un mindful that many clinicians are engaged in the control of venereal disease merely from the standpoint of health officers and that avail able funds do not admit of intensive or long-continued treatment and are often used for sterilization purposes for public health protection. That there is danger to the public health in dismissing patients from treatment too early is seen in the claims of some observers who state that as larger numbers of infected individuals are brought under surveillance opportunity is afforded to observe an increased number of patients in the infectious second stage, which condition they believe to be due to inadequate treatment. " In the light of present knowledge regarding the subsequent dan ger to both the individual and community by ineffective and inade quate treatment the service urges that great care be exercised in recording case histories ; in referring patients for intensive treatment to health centers or competent physicians to continue treatment when the clinic is unable to do so; and keeping cases of positive syphilis under proper observation until the period of danger for both the individual and the community has passed." Writing on the principles in the treatment of empyema in Surgery, Gynecology, and Obstetrics for March, 1922, Dr. Carl A. Hedblom says : "The aim of all forms of treatment of nontuberculous empyema is to evacuate the pus, combat sepsis, and restore the structures and functions to as nearly normal as possible, all without undue risk. Difficulties in accomplishing drainage may be due to interference with respiration resulting from a partial collapse of the lungs inci dent to opening the pleural cavity or there may be secondary en capsulated pockets. The virulence and metastatic nature of the infective organism may be beyond our powers to combat. In a chronic case structural changes in the lung and in the wall of the chest may be beyond repair. "The data with regard to the treatment of empyema constitute one of the most interesting chapters in the history of medicine. It is a remarkable fact that while the condition was recognized and treated by the ancients and spasmodically treated throughout the centuries it is only 60 years since Walter, an American, first excised a segment of normal rib in order to establish drainage. 512 Vol. XVII. NOTES AND COMMENTS. "Although numerous intercostal drainage devices continued to be rediscovered and reintroduced periodically, rib resection came to be the standard operation with or without one or another of the numer ous valve-drainage devices. Most cases were of the frankly puru lent type at operation, and the mortality, though on the average high, was considered unavoidably so. Then came the great pandemic of streptococcus pneumonia and empyema. The forbidding mor tality resulting from simple rib resection and drainage in these cases and the prompt and great reduction in mortality following the in stitution of ' closed drainage ' with irrigation seemed to indicate that the last word in the treatment of acute empyema after all had not been spoken. Physicians were forced to recognize the danger of pneumothorax in these cases. It was also discovered that it is possible to employ suction rather than gravity for the drainage of pus and that irrigation, particularly with Dakin's solution, was of distinct benefit. " The assumption seems rational that the closed method is indi cated in very ill patients with acute empyema of any type, particu larly with pulmonary involvement. A to-and-fro suction sound is often heard following opening of the pleural cavity in these cases, indicating a partial collapse of both lungs. In a patient already critically ill this added insult may be the last straw. Air-tight aspiration, on the other hand, tends to increase respiratory capacity by expanding the lung an amount equal in volume to the pus as pirated, which may mean full expansion of the lung from almost complete collapse. " In combating sepsis the most important consideration is the thorough evacuation of the pus. This can be accomplished prob ably more thoroughly by aspiration and flushing of the cavity with a cleansing solution than by rib resection and gravity drainage alone. The relative superiority of the hypochlorite solution is prob ably due not only to its germicidal properties, which are considerable when it is used copiously, but also to its characteristic property of separating all necrotic material and pus from the living tissue. Fill ing the cavity through one air-tight tube, besides being simpler and easier than rib resection, followed by an attempt to place a number of Carrel tubes, would seem to insure better contact between the fluid and all parts of the cavity. Such procedure also tends to dis solve the shelving partitions. It is probably important to use large amounts of fluid at frequent intervals during the first days to pre vent walling off of any part of the cavity. "The communication of bronchial fistulse with empyema cavities may often be proved by injecting methylene blue into the cavity. Dakin's solution, generally speaking, is contraindicated in the pres ence of large fistula?, but normal saline solution may be used. No. 3. 513 NOTES AND COMMENTS. "In a large proportion of cases of chronic nontuberculous em pyema, very material reduction or complete obliteration of the cavi ties may be secured by irrigation with hypochlorite solution. An extensive plastic operation, besides the hazard it involves, is dis abling, as pointed out by Graham, because of the marked reduction it may produce in vital capacity." The department of health, city of New York, has called attention to the fact that of three cases of smallpox discovered in that city recently, which were of common origin, one was treated for several days as syphilis. Such a mistake is especially apt to occur in those cases of mild clinical symptoms nowadays so common, and when the opportunity for extended examination of an individual is limited. i NAVY NURSE CORPS. MARIA ROBERTA: A TRIBUTE. By D. V. Kwioht, Chief Nurse, Untted States Navy. Somewhere, sometime, I hope to see published, where all the world may read, a fitting tribute to the Medical Department of the Navy for what it has done for the natives of Guam. The medical officers who were ordered to Guam immediately after this island became a possession of the United States found the natives in great need of medical and nursing care. Overcoming what seemed to be almost insurmountable difficulties, they established a hospital, and native women were instructed in the nursing care of the sick women and children. First among the women who received this instruction was Maria Roberta. Maria Roberta was born on the island of Guam about 45 years ago. The world to Maria is the small island upon which she lives ; and she being of a practical nature, I doubt whether she has ever strayed from this island, even in fancy. She has not had the advantage of a school education, but as a beautiful flower will sometimes be found growing in the most unexpected places amid the most unfavorable surround ings, so Maria Roberta grew, if not in physical beauty (though her tall, well-built, graceful form could be so considered), in beauty of character. 'Her keen mind, well-developed sense of honor, all the gentleness and lovableness of the native, with a great desire to do for others, have made her an outstanding and valuable person on the island. When I reported for duty in Guam August 27, 1914, I found that the principal duty of the chief nurse of the Navy Nurse Corps at this station was the instruction of and the responsibility for the native nurses. In a short time it became evident that in order to give the necessary nursing care to the native women and children who were patients in the hospital and to provide a nurse for the dressing stations at villages distant from the hospital more native nurses were needed. It seemed impossible to supply this need with desirable material. Upon inquiry, I learned that many of the better class of native girls were willing, even anxious, to do this work, but there was an objection on the part of the parents. Guam having been a Spanish possession, some of the Spanish conventions were 515 516 Vol. XVII. NURSE CORPS. still adhered to by the better class natives, and parents would not allow their daughters to leave the confines of their homes unchaper- oned. Not being able to, nor having a desire to, change these con ventions, it became clear to me that to provide for what I knew to be a great need it would be necessary to first obtain a chaperon for the native nurses. Having heard much about Maria Roberta from the nurses, there was no doubt in my mind that she was just the person for this place. I sent for Maria. She came to see me at the hospital and told me that she could not accept my offer as she had an adopted child to care for and the pay was not sufficient. (She had left the hospital some years previous to make a home for this orphan child which she had adopted.) After discussing the matter with the com manding officer, he decided that out of the fund for the care of sick natives Maria was to be paid a sufficient amount for her needs and the needs of the child. Maria being well known on the island and the fact that she was engaged as "official chaperon" for the native nurses removed the objection of the parents to the extent that it be came possible to get the required number of pupil nurses. Maria lived with the nurses; was with them constantly while in the hos pital, and when they were off duty and wanted to go home she accompanied them to their homes, where she was relieved of her responsibility by their parents, who returned them to the hospital not later than 10 p. m. This constant supervision was accepted very gracefully by these girls, as they were accustomed to it and were very fond of Maria. They also knew that nothing stood between Maria and her duty. One evening just as we were sitting down to dinner I heard foot steps on the walk at the entrance to the dining room, and looking out I saw Maria Eoberta with two shrinking forms of men, one gripped firmly in each hand. One was a native policeman in full uniform, club " 'n everything " except his shoes, which he was carry ing in the hand not held by Maria. She, with her keen sense of duty predominating, gave the policeman a shove into the dining room, then she gave the other man a shove, placing them before me, and told me that she had found these two men just outside of the hospital wards talking to two of the native nurses, giving the names of the nurses. She realized that she had caught these two Romeos " red- handed " in a most glaring offense. I informed Maria that we would take them to the police station. The policeman very meekly asked permission to put on his shoes. This permission was granted, after which Maria and I proceeded with the two frightened, non- resisting offenders to the police station, where they were locked up for the night, and the next day they were tried and found gulity on a charge of trespassing. But in this South Sea island, with its balmy climate and its tropical beauty making it a veritable fairyland. No. 3. 517 NURSE CORPS. which seems to exude romance, and when the girl is young and beau tiful, who can blame mere (native) man for trying to sidkjtep even a Spanish convention? Oh, yes; it takes a Maria Roberta's sense of duty to hold this convention intact, as not only the men but the girls also are willing to do a bit of side-stepping on the matter of conventions. When little Francesca, who in appearance was like a bronze doll, was admonished for flirting, she responded with : " But, Miss Knight, it is my custom." If any doubt as to Maria's authority existed in the minds of the people prior to the above-mentioned epi sode, no doubt remained following it. Maria's field of usefulness is not limited to being "official chap eron" to the native nurses. Her ability to understand and speak English makes her services as interpreter in the instruction of the nurses and in transmitting orders most valuable. The instruction of the nurses is adapted to their mentality and the needs of the people. A large part of their work is obstetrical nursing, in which Maria is most efficient; and, knowing the customs and living condi tions of the people, she was most helpful in adjusting the work to their needs. The training of Maria Roberta and other native women, who became quite efficient in the care of obstetrical cases, was a great help to the medical officers in dealing with the question of the midwives of the island. When the commanding officer of the hos pital ordered that all midwives pass an annual examination in order to keep their licenses to practice, there was much protest on the part of those who could not meet the requirements of the examina tion, which was entirely practical. This action on the part of the commanding officer resulted in a great decrease in infant mortality and blindness. Again Maria Roberta's usefulness became evident, in that she knew personally all the midwives, where they practiced, how they did their work, whether they were meeting the require ments set by the medical officers—and to Maria these requirements were unconditional. She had a way of appearing just at a time to get first-hand information, and well the midwives knew that—nothing stood between Maria and her duty. Knowing this, they respected her. Not least among Maria's characteristics is her marked maternal instinct, which was demonstrated in her adoption of a child. This child has been the source of much happiness to Maria and is to her the one source of diversion from the routine duties of the hospital. As the years go by this child gives great promise of repaying her for her devotion and sacrifice. Other children have been fortunate enough to be the recipients of Maria's great generosity. Among them is Benadino. When I reported for duty in Guam, Benadino was nearly 3 years old and had been a patient in the hospital about 646—22 10 518 Vol. XVII. NURSE CORPS. two years, or so long that if he ever had any people who were inter ested in him no evidence of this interest remained. He apparently belonged to the hospital and was considered the hospital " mascot." He was a bright, cheery little fellow, a bit vain, and had the Cha- morro love for bright colors. He objected to wearing the plain gowns provided by the hospital for other children and always found some one to encourage his vanity. On special occasions Maria Roberta could always produce Benadino in gala attire, and it would be difficult to say whether Benadino or Maria derived the greater happiness from the effect. Service conditions make frequent changes in the Navy personnel at Guam. It is Maria Roberta who remains and who holds together the fabric of the work built up by the Navy nurses. BOOK NOTICES.

D., assistant in pediatrics and chief of outpatient department, University of California Medical School. C. V. Mosby Co., St. Louis, Mo., 1922. When sickness overtakes a baby, the management of its case de mands many departures from those methods of treatment which are quite appropriate when we, as physicians, have to deal with older people. Many good books have been written on the diseases of chil dren, but, so far as the reviewer is aware, until the appearance of this volume there existed no book in the English language which dealt with the peculiarities of disease as it occurs in infants, that is, dur ing the first two years of life. This fact alone should give the book a place in medical literature. A perusal of the text reveals the fact that the book contains much of real value to the general practitioner, and it would appear to be of great use to the young physician whose professional reputation often is founded upon his successful man agement of the sick baby. In this book the whole subject of the management of the sick infant is ably and concisely treated in three sections: the first of 519 520 Vol. XVII. BOOK NOTICES. which deals with the predominate symptom noted in an infant's illness, such as vomiting, diarrhoea, constipation, nutrition, hemor rhage, pain and tenderness, convulsions and syncope, fever and cough. In the second part, the authors discuss the various disease entities which are met during infancy; and in the third, they con sider some very practical methods of treatment which have been found to have stood the test of time in their practice in San Fran cisco. Each method is given in detail. Of special convenience are the chapters on formulas andx recipes for infant's food, and on the employment of drugs in pediatric practice. The text covers 642 pages and is amply illustrated. Although the naval medical officer at sea is rarely called upon to treat sick infants, pediatrics forms a considerable portion of one's practice at large naval stations, Marine Corps posts, and foreign shore stations, hence this book is recommended to medical officers serving in those situations, and especially to surgeons of transports, who will find in it the solution of many of the difficulties which the management of the sick infant presents at a time when pediatric specialists are not available for consultation, (w. m. k.) The Thyboid Gland. Clinics of George W. Crile and Associates. Edited by Amy F. Rowland. W. B. Saunders Co., Philadelphia, Pa., 1922. The number of cases of endemic goiter and hyperthyroidism en countered among recruits coming from the region of the Great Lakes and from the Northwest makes this volume on the thyroid gland of special interest to the naval medical officer. It is not a textbook on the subject, but rather a presentation of the Crile clinic at work, and aims to present in a series of papers the theoretic and practical viewpoints of Doctor Crile and his associates to-day. Much new knowledge has been developed in the Crile clinic con cerning the thyroid gland, and the discussions which comprise the text center about a number of important points. Endemic or simple goiter has been found to be a geologic deficiency disease due to a lack of iodine in the organism, and by the proper administration of iodine to the pregnant mother and to the child, up to and through the period of adolescence, endemic goiter may be prevented. These facts are brought out in a well-written paper on the " Prevention of simple goiter in man," by Dr. O. P. Kimball, dealing with the prophylactic work carried out by him in the public schools of Akron. Ohio. The practical application of the principle of the prevention of simple or endemic goiter is now on such a firm basis that a few gen erations hence will see the end of this condition, as well as of cretin ism in every civilized nation. Xo. 3. 521 BOOK NOTICES. In the clinic it has been found that after the twenty-fifth year of age iodine exerts little or no beneficial effect on goiters ; also that by the improper use of iodine or thyroid products many cases of quiescent goiter, especially of the adenomatous type, are converted into exophthalmic goiter or hyperthyroidism, and that this induced hyperthyroidism is essentially identical with spontaneous hyper thyroidism. A practical point dealing with a paper by Dr. Allen Graham on the " Diseases and pathology of the thyroid gland," is the fact that about 90 per cent of all malignant tumors of the thyroid arise in the fetal adenomata. Therefore, iodine given the pregnant mother may prevent fetal adenomata, hence cancer of the thyroid in the offspring. The relations between diseases of the thyroid gland and laryngeal function are discussed by Dr. J. M. Waugh, and the differential diagnosis of diseases of the thyroid gland by Dr. John Phillips. In a short paper Dr. R. S. Dinsmore brings to our attention the advantages of the adrenalin sensitization test for hyperthyroidism which was first used by Goetsch to establish a differential diagnosis between hyperthyroidism and early tuberculosis in patients pre senting the syndrome of loss of weight and strength, fatigue, and slight elevation of the temperature, in whom the physical signs and X-ray findings for tuberculosis were negative. The role played by the radiologist in the diagnosis of goiter is discussed by Dr. B. H. Nichols, and the value of basal metabolism studies in exophthalmic goiter by Dr. C. D. Christie. Basal metabolism estimations provide a valuable, but not a specific, test for the presence of hyperthyroidism. They are of value in the differential diagnosis of border-line cases, but are of little value in the determination of the operability or prognosis of cases of hj'per- thyroidism. Any case of hyperthyroidism is operable, or may be made operable by a short period of active treatment involving a planned regimen of rest and diet ; and in view of the surgical results obtained, Crile advises surgical treatment for all cases without regard to the degree of hyperthyroidism. Heretofore, the only valid objection to surgical treatment has been the mortality; but with modern methods the mortality is practically eliminated; much time is saved and a more certain cure is achieved thftn with the X-ray treatment or any of the medical treatments advocated. About one-third of the volume is devoted to the consideration of the preoperative; the operative, and the postoperative management of exophthalmic goiter. Apparently this book is the first of a series of clinical volumes which will present various subjects as handled at the Crile clinic in 522 Vol. XVII. BOOK NOTICES. Cleveland. The series promises to be so valuable that we trust the next volume will soon make its appearance.

M. k.) Surgical and Mechanical Treatment of Peripheral Nerves, by Upton Utookev, A. M., M. D., associate in neurology, Columbia University. W. B. Saunders Co., 1922. This book is a most practical, modern, and especially scientific pre sentation of this subject. Throughout the book the author shows evidence of exhaustive study and careful analysis, with extensive reference to the writings of eminent scientists whose works have fallen within the scope of his subject. The book is systematically arranged; the opening chapter dealing with the anatomy of the spinal nerves, the second chapter with nerve degeneration and re generation; two very important preliminary sections in preparation for a proper comprehension of the following chapters which follow in very logical sequence. While it would seem that the author devotes- considerable attention in his chapter on " Methods of Nerve Repair." to the standardization of terms with reference to these methods, this is, indeed, essential in order that the terminology may properly ex press the type of operation. This chapter describes in a very clear manner various methods of nerve repair. The operative technique is very well described with its contiguous perplexities, and the drawings are sufficiently descriptive to get a good mental picture of the pro cedures. The chapters dealing with the mechanical and surgical treatment of special nerves is excellent. The anatomy is accurately presented, both descriptively and by splendid cuts, as well as sur face projection pictures showing the relative position of the nerves to surface anatomy. The discussion of cervical ribs, in the chapter on the brachial plexus, is noteworthy and completes an excellent chapter. The nerves of the arm, so frequently subjected to injury, receive their proper apportionment of discussion and space, with sufficient attention devoted to the mechanical side, as well as the No. 3. 523 BOOK NOTICES. surgical side of the treatment.

Second edition. C. V. Mosby Co. St. Ixmls, 1922. The consideration of the subject of clinical tuberculosis as found in these two volumes is complete and thoroughgoing. As a work of reference the treatise fills a very definite and important place in medical literature. Practically every phase of the disease is discussed in considerable detail, the author's wide knowledge of the subject and his pleasing style combining to give a production which one is glad to sit down and read at length. The illustrations, which are numer ous, are a distinct addition to the work. The author has taken ad vantage of the opportunity offered in a work of this scope to give the reasons, as they appear to him, for many of the signs and symp toms of the disease. His classification of symptoms according to their causation and his discussion of the part which the nervous system plays in bringing about the clinical manifestations of tuberculosis are very instructive. The greatest value of the work, however, lies in its more practical considerations. The author is more peculiarly fitted because of his experience to discuss the diagnosis and especially the treatment of the disease, and this he has done in a very clear, comprehensive, and foiweful fashion, (l. j. h.)

To the Editor : Twice during my tour of duty as medical officer of this sta tion recruits have been invalided from the service because of mental inferior ity. These cases have impressed me with the unnecessary expense they have meant to the Government. In both cases the applicants falsified as to their education ; and without facilities for carrying out a standard test to determine their mental age the mistake was made of considering their knowledge as an accurate index of their intelligence. The action of the Board of Medical Sur vey in these cases is based on the results obtained by the Stearns group test and the Stanford revision of the Binet-Simon test. The value of these tests can not be overestimated, not only from the point of view of detecting applicants who are totally unfitted for the naval service, but in determining the adaptability of the recruit to any special duties which might be assigned him during his naval career. For this reason I have felt the need of facilities for making some test which could be considered standard and which would make it possible to grade our applicants in standard terms. In other words, is it practicable to advance the place for making these tests from the boards of medical survey at training stations to the recruiting stations? Lieutenant, Medical Corps. The question asked in this letter is similar to others that have been received by the bureau at intervals in the past. During January of this year a set of three or four simple psychometric tests were submit ted, with the suggestion that they be used as a standard test at re cruiting stations. After careful consideration of the subject at that time by a board appointed for that purpose, the opinion of the board was that the adoption of such tests was impracticable.1 The Stanford revision of the Binet-Simon test is possibly the most reliable and most generally used of the numerous psychometric tests. In a sense it is an intelligence test. "While the intelligence tests are important, and while taking them in a routine manner one can get a good deal of information from the patient (applicant), often 1 U. S. Naval Medical Bulletin, June, 1922. 525 526 Vol. XVII. QUERIES. information of matters that lie deeper than mere questions of in telligence, still they are by no means all-sufficient. * * * These tests are valuable in skilled hands for the more pronounced degrees of defect, but as development proceeds they become progressively more unreliable in proportion to the increased psychic mass, the impossibility of standardization because of the wide individual differences, and the greater probability of distortion from unknown emotional sources." 2 Psychological tests are of value only when conscientiously carried out and their findings correctly interpreted. Their impracticability with respect to their general adoption by the recruiting service of the Navy lies in the fact of the time required in each individual case, and in that their correct interpretation requires an examiner who is either a trained psychologist or psychiatrist, and preferably both. The Army conducted some very exhaustive tests* with regard to these matters, but in order to do so they developed an entirely separate corps of specially trained psychologists who were assigned to the recruit depot. Opinion was divided as to the ultimate result; and, as a matter of fact, we are in frequent contact with men who have successfully passed the Army tests and adapted themselves to their environment while in the Army, but who on subsequent en listment in the Navy do not adapt themselves and eventually are surveyed because of mental deficiency or constitutional psychopathic tendencies. White says, " Xo set of tests can be applied in a purely automatic way nor will such tests in any way take the place of knowledge and experience on the part of the examiner. In the most skilled hands the results, expressed in terms of psychological age, are but rough approximations. It has been well said that the only way to tell whether a person is feeble-minded or not is to live with him for six months. Reactions to life situations are immensely more valu able and illuminating than reactions to psychological tests."4 For the present it would seem that the best way of eliminating undesirables at the recruiting stations would be— (a) By assigning to recruiting duty only such officers who have had sufficient experience in a cruising vessel to appreciate the type of recruit best suited for naval duty. (b) By brief study of the personality of each applicant through a series of questions selected for the purpose of determining his pre vious activities, in an effort to elicit any abnormal, unstable, or asocial tendencies. * Diseases of the Nervous System, Jelllffe and White, 2d edition. * Memoirs of the National Academy of Sciences, vol. 15. 4 Outlines of Psychiatry, White.

Phyllodromia. Sodium fluoride is considered one of the most efficient roach ex terminators. It is best used mixed with an equal part of powdered sugar. After thoroughly cleaning the locality which harbors the roach, the sodium fluoride mixture is liberally sprinkled or blown by means of a powder blower into corners, drawers, closets, behind pantry drain boards, and into other places of concealment. It must be distributed in such a way that it will not be swept up or removed. It should be allowed to remain and act for weeks at a time. It can be sprinkled along the back parts of shelves and out of the way in the recesses of drawers and in filing cases. This substance is not injurious to books or other materials nor to the crew. It forms the basis of most roach powders now on the market. The use of sodium fluoride seems to be too slow a process of eradi cation when large numbers of roaches are in evidence, in which case a 5 per cent mixture of cresol in kerosene is very effective. The mix ture should be sprayed freely by means of a powerful mechanical sprayer into any place harboring roaches. The process should be repeated once each week for several weeks, when very few roaches will be found. This mixture does not stain, although its odor is offensive to some. In the eradication of cockroaches, one must keep in mind the neces sity of keeping all pantries and storerooms free from crumbs or other food remnants which attract roaches. - All Ihe apparatus required for use aboard ship packed in 2 cubic feet of space.

INSTRUCTIONS TO MEDICAL OFFICERS. A SIMPLE TYPE OF PORTABLE STEAM BISHTFECTOR. Bj R. F. Jones, Lieutenant Commanaer, and P. Richmond, Lieutenant, Medical Corps. United States Navy. During the World War, ships, particularly transports, were equipped with large steam sterilizers for the disinfection of clothing and bedding. Such sterilizers occupied considerable space and there fore were usually placed on " topside." Moreover, they were costly to install and operate, and when exposed to the weather required con stant attention. Since it is still necessary to sterilize clothing and bedding occasionally, a suitable disinfecting apparatus should be provided, preferably one which could be stored in a small space and easily transported. Such a portable disinfector could also be used by landing parties and marines on shore duty. The " sack " steam disinfector, invented by Col. P. S. Lelian, R. A. M. C, professor of hygiene, Royal Army Medical College, seems to meet these specifications. The British Army is said to have used the M sack " steam disinfector with success during the World War. A series of experiments were carried out at the Naval Medical School, Washington, D. C, to determine the efficiency of this dis infector. Before describing the results of the experiments it might be well to give the reader an idea of the appearance and method of operation of the "sack" steam disinfector. CONSTRUCTION AND WORKING PRINCIPLES. The construction of the apparatus is very simple. It consists of a canvas bag, somewhat similar to the ordinary Navy hammock bag, 529 530 Vol. XVII. DIVISION OF PKEVENTIVE MEDICINE. 4 feet long and 2 feet in diameter, with a circular wooden bottom and a draw string to close the top. The canvas of which the bag is made is impregnated with a heat and waterproof paint to make it impervious to steam. A 1-inch rubber hose is attached to the sack near its base. Steam may be obtained from a steam line or from a copper boiler by making the necessary connections. The copper boiler, with heating appliances, is part of the equipment. A metal disk from which coats, suits, or other clothing may be loosely hung to avoid creasing and rumpling is also provided. This is not used when clothes are tightly packed in the bag. Clothing, bedding, etc., may be packed tightly into the sack or hung loosely to avoid rumpling. In the first instance the sack is packed as would be done with a sea bag; it is then inverted and suspended from a suitable support. When suits or other clothing are to be sterilized, the sack is first suspended in an inverted posi tion and then the clothing hanging from the disk is pulled up into it by means of pulleys. In either case the outlet of the sack is partially closed by means of a purse string. Steam obtained in one of the ways described above is now allowed to flow into the sack through the rubber hose. As steam enters its base an equal volume of air is expelled from its down- turned mouth, which has been partially closed. Gravity forces each entering volume of steam to spread horizontally across the sack, dis placing the heavier air downward from the interstices of the cloth ing. This stratum of steam immediately condenses and, by the in tense latent heat thus liberated, heats to a high degree every fiber with which it comes in contact. A fresh wave of steam then enters the resultant partial vacuum, fills it, heats its contents to the con densation point, and sweeps onward to repeat the cycle in another layer of clothing immediately below. Heating of the contents thus progresses, layer by layer, until there is free escape of steam from the mouth of the sack, indicating that air has been entirely displaced from the sack and the contents heated throughout. However, com plete sterilization is not effected until steam is allowed to flow from the mouth of the sack for from 15 to 30 minutes, depending on the volume of steam entering the sack. But in this connection it should be stated that insects and nonspore-bearing organisms are killed in a much shorter time. EXPERIMENTS TO TEST EFFICIENCY OF SACK. The sack was tested under varying conditions. The first tests con sisted of packing bedding and clothing tightly into the sack and ob No. 3. 531 DIVISION OF PREVENTIVE MEDICINE. tabling steam from a copper boiler which was heated by a pressure kerosene stove. The accompanying diagram illustrates the locality of thermometer, culture media, eggs, or animal parasites which were used to deter mine the efficiency of the sack as a sterilizing agent. The numbers shown thereon were used constantly throughout all experiments. In every instance the thermometer, culture media, eggs, or animal parasites were placed in the center of tightly wrapped bundles of clothing.

From an examination of the above table it will be noted that all material packed in the sack was not sterilized after steam had been, allowed to flow from the mouth of the sack for 2 minutes, although the manufacturer of the apparatus in his descriptive pamphlet claims that complete sterilization should be obtained within 2 minutes after steam commenced to flow from the sack. This experiment was repeated several times and invariably the same results were obtained. Bedbugs, which are killed at a temperature of approximately 76° C, were not killed when placed at position No. 6 for this time. Here it might be stated that it required approximately 20 minutes to get a full flow of steam through the mouth of the sack. All nonspore-bearing organisms and bedbugs were killed when steam was allowed to flow from the sack for 15 minutes, although spore-bearing organisms were not killed in this time. Therefore, this length of exposure is not deemed sufficient to sterilize. However, it would be perfectly safe to use the sack under similar circumstances to destroy vermin. When steam was allowed to flow from the mouth of the sack for 30 minutes all organisms and parasites were killed. In our opin ion, when steam is obtained from an improvised boiler or the boiler furnished with the apparatus, it would be safer to lengthen the time of operation to 30 minutes in order to be definitely certain of good results. In an endeavor to simulate conditions under which the sack is to be used aboard ship, steam was obtained from a steam line by in troducing a reducing valve between the sack and the steam line having a pressure of 75 pounds. The pressure of the steam entering the sack was approximately 5 pounds per square inch. The follow ing table shows the results obtained : 646—22 11 534 Vol. XVII.

DISCUSSION OF TABLE II. By reference to Table II it will be seen that the sack is effective as a sterilizer for all organisms when the steam is allowd to flow freely out of the mouth for 15 minutes, but that only nonspore-bearing or ganisms will be killed after 2 minutes. The results were apparently the same whether the bag was packed tightly or the clothes hung loosely in the sack. It is obvious, from a comparison of the two tables, that it is desirable to have the steam entering the sack under slight pressure and in considerable volume. It may be possible to obtain some pressure and a considerable volume of steam with the heating appliance furnished with the apparatus, but we were unable to do so in a series of some 15 tests. It was never possible to get a flow of steam in any way comparable with the flow when the sack was connected with the steam line. Not only does steam sterilize more rapidly when under pressure, but there is also less condensa tion, which is evidenced by the drier condition of the clothing when removed. Furthermore, steam obtained from a steam line penetrated the clothing more rapidly. PRACTICAL USES OF THE SACK DISINFECTOR. The compactness and simplicity of this apparatus makes it espe cially suitable for use aboard ship where connection between the sack and a steam line can be easily made by interposing a reducing valve to reduce the pressure below 25 pounds. Whenever steriliza tion of clothing, bedding, or mattresses is required the "sack" can be rigged in a few minutes and can be safely used to disinfect cloth ing and bedding contaminated by bacteria and parasites. When not in use it can be stowed in approximately 2 cubic feet of space. The sterilizing power is approximately equal to that of an Arnold steam sterilizer, and in the event of the autoclave being out of order, large quantities of surgical dressings, especially bulky packages of shell- wound dressings, towels, gowns, etc., can be safely subjected to fractional sterilization with this apparatus. An outfit with all the necessary appliances for use where boiler steam is not available will pack in about 4 cubic feet of space and does not weigh more than 60 pounds. Such an outfit could be used to advantage on expeditionary duty, particularly by marines, who can not readily transport heavier appliances. If necessary, supplies of surgical dressings for a temporary field hospital could be sterilized. By utilizing the same principles aboard ship a small compartment capable of being made practically air-tight could be converted into a sterilizing chamber. Satisfactory results from such an arrange ment are reported in the annual sanitary report of the U. S. S. Wyoming. The only alterations required would be the installation 536 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. of two pipes, controlled by valves ; one located above, and connected with a steam line, and the other below for exhausting the chamber of air or steam. As soon as steam flows freely from the lower pipe, the valve controlling this should be closed and steam allowed to flow into the room until there is slight bulging of the bulkheads, indicating that sufficient pressure has been obtained to permit thor ough penetration. The efficiency of such a procedure can be tested by placing hens' eggs at various parts of the room. Live steam should be allowed to flow into the room for about 30 minutes. Under ordinary circumstances the eggs would be " hard boiled " in this time. CONCLUSIONS. 1. The "sack" disinfector is particularly useful for the military services on account of its compactness and portability, and the writers are of the opinion that it should be adopted as permanent equipment of the Navy and Marine Corps. 2. When steam is obtained from an improvised boiler, sterilization should continue for 30 minutes after steam flows freely from the mouth of the sack: when connected with a steam line this time may be reduced to 15 minutes. 3. Bedbugs and other such insects may be destroyed in a third the time required for complete sterilization. 4. The time required for sterilization is the same when clothing is packed in the sack tightly as when hung loosely. HEALTH CONDITIONS OF THE NAVY. Health conditions of the Navy for the four-week period ending August 5 were not quite, so good as for the previous month. The annual admission rate for all causes for the four-week period ending August 5 was 540 per 1.000 per annum as compared with 385 per 1,000 per annum for the four- week period ending July 8. However, the health conditions were better than they were at a similar period last year. The morbidity rate for diseases only was 471 per 1.000 per annum and for accidents and injuries, 69 per 1.000 per annum. The admission rate for the communicable diseases, exclusive of influenza and the venereal diseases, for the four-week period ending August 5. was 37 per 1,000 per annum. It will be seen in the fol lowing table that malaria caused approximately half of the admis sions for the communicable diseases : Xo. 3. 537 DIVISION OF PREVENTIVE MEDICINE.

The progressive average rate for venereal disease for the year is now 108 per 1,000 per annum. Although a considerable number of recruits have been received at training stations since about June 1, there have been few com municable diseases reported from any of the training stations. Health conditions of the forces afloat are excellent. Few com municable diseases have been reported during the past month. NOTES FROlIt THE NAVAL TRAINING STATION, HAMPTON ROADS, VA. During the month of June there was a great deal of rainfall, resulting in many pools of water being present under houses and bungalows, and a consequent increase in the prevalence of mos quitoes. Oiling of all surface water has been continued, but inas much as it is difficult to use an oil spray in the confined space under buildings, no doubt, many pools of water were missed. Toward the end of the month the weather cleared and became dry, and the decrease in number of mosquitoes was quite noticeable to those who have occasion to be in the open in the early morning and evening. Flies have apparently decreased in numbers, and can not be said to be present in undue proportion. Parts of the training station have been inspected every day, and it is believed that there are no breeding places for flies in this territory. There have been no diseases contracted on the station during the month of June attributable to either mosquitoes or flies. Cases of malaria have come up from the Tropics, and some of them have had acute exacerbations while here, but no secondary cases have 538 Vol. XVIi. DIVISION OF PREVENTIVE MEDICINE. arisen. Until recently, no anopheles mosquitoes were found at this place, but they are here now; therefore, all men who have had malarial fever in the past are now required to sleep under nets. The water supply of the station is obtained from the water mains of the city of Norfolk, from which it is pumped into a distributing reservoir oh the base. This has been the cause of considerable concern during the month because our laboratory reports have shown that the colon bacillus has been persistently present in the water. Keports from the health department of the city of Norfolk early in June showed that the water was infected with that organism. The city water supply is chlorinated by the Wallace and Tiernan apparatus, using compressed chlorine gas. The amount of gas used was promptly increased by the city, and for a time it was found that the water received into the reservoir at the base was apparently free from harmful bacteria. However, toward the end of the month colon bacilli again appeared in the water. As soon as it was found that the organism was present in the water, the chlorinating apparatus installed at the power house at the naval operating base was put in operation and, on June 10, we began using 2 pounds of chlorine to the 2,000,000 gallons of water used each 24 hours. This is in the proportion of 0.26 part per 1,000,000. Our apparatus injects the chlorine into the water between the power house and the reservoir. The quantity of chlorine was gradually increased until the 16th, when 5 pounds of chlorine, corresponding to 0.3 part per 1,000,000, was used. Cultures were made every other day. On June 22, 6 pounds of chlorine, corresponding to 0.36 part per 1,000,000, were used in 24 hours, and the last report, dated June 23, showed an improvement; it being impossible to isolate colon bacilli in less than 10 c. c. of water. It was known that the station reservoir had an accumulation of dirt on the bottom, since it had not been cleaned for more than two years. Although it was be lieved that this reservoir did not form, at that time, a real menace to the personnel of the station, yet recommendation was made to the public-works officer that the reservoir be thoroughly cleaned. Health conditions.—The total number of admissions to the sick list for the month of June was 206 ; this is against 87 for the month of May. This, however, does not indicate the actual amount of ill ness occurring among the personnel, inasmuch as the 206 admissions includes 54 recruits admitted for survey, 65 recruits in whom in testinal parasites were found, and 20 men, admitted with no disease, and placed under observation as measles contacts —total of 139, which leaves but 67 cases of routine illness to be compared with 87 cases that occurred in May. From this it would appear that the health of the command has been excellent. No. 3. 539 DIVISION OF PREVENTIVE MEDICINE. Recruits. —From the time recruiting started, in May, to June 30, inclusive, 1,036 men were received at this station. Of these it was found necessary to hold out 70, or 6.75 per cent, because of various disqualifying disabilities, as listed below: Nephritis, chronic (interstitial and parenchymatous) Color blindness Otitis media, chronic Valvular disease, chronic cardiac Hypermetropia Union of fracture, faulty Astigmatism Atrophy of muscle Myopia ritis, chronic ysis of nerv e litis maxillary Total surveyed Attention is invited to the large number of cases of chronic nephritis, 34, or 3.21 per cent of all recruits. It is our custom, at this station, to examine the urine of every recruit and when albumin is found to be present the urine is examined chemically and mi croscopically every day until it is determined whether the recruit has a transitory albuminuria or Bright's disease. Of the 34 men who were discharged, as reported above, all were shown conclusively, after repeated examinations, to have chronic Bright's disease. Aside from the 34 positive cases, '29 other men showed albumin on the first examination, followed by two or three negative tests. In practically all of these latter men there was a history of their having drunk corn whisky or other " bootleg " liquor within a day or so prior to their examination. It is also interesting to find that all of these men, in whom albumin was persistently found, denied absolutely that they had been drinking liquor of any sort. Many of them pre sented a blood pressure in excess of normal for their age and physique, and most of them gave a history of some acute infection. Aside from the 34 men who were finally discharged, 17 others were under observation as nephritis suspects for a period of several days, but were eventually outfitted and sent on through the training course. In the recruit-examining room the hospital corpsman, assigned to make the examination of urine of all these men, was on duty for six months in the naval hospital in Charleston, S. O, where a por tion of his daily work was the routine urinalysis of all urine samples of patients in the hospital. His work was checked personally by the medical officer of the examining room, and the findings were later 540 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. substantiated at the base laboratory. This eorpsman states that, in his experience, the percentage of albuminurias in these recruits was much higher than in routine hospital patients. This experience raises the question whether it is not advisable for the medical officer in each recruiting station throughout the country to make a uri nalysis of every man he is inclined to accept and throw out those who show albumin. The 11 cases of color blindness that were discharged by medical survey were examined first with the Jennings test and then the Holmgren skeins. The examination was repeated several times, and the board of survey, as well as the senior medical officer, - is thoroughly satisfied that there was no question in the diagnosis of their condition. Sick quarters. —The month of June completes the first year of our organization in which sick quarters has played such an important part. The plan originally made has been followed with very few modifications, and has been found to work most admirably. All activities of the base have cooperated to the fullest extent; there has been no friction, and it is believed that all activities will agree that the presence of the facilities offered by sick quarters have given them a sense of security they could not possibly have felt had the old base hospital gone out of commission, leaving nothing in its place. During the year 3,209 cases have passed through sick quarters, 898 of which were transferred to the naval hospital at Norfolk for treat ment. Of the total (3.209) 2,625 were admitted from the training station, 355 from the receiving ship. 195 from the air station, and 34 from miscellaneous sources, such as submarine base, ships in the harbor, etc. In addition to the original plan of work, one medical officer has been assigned to the care of the families of Navy per sonnel, and this activity has grown to such an extent that during the month of June this officer covered 1.041 miles attending to his duties. PARIS GREEN AS A LARVICIDE FOR ANOPHELINE LARV-ffi. The following is an extract from an article appearing in the United States Public Health Service Report of December 9, 1921. entitled "Arsenic as a larvicide for anopheline larvse," by M. A. Barber, special expert, and T. B. Hayne. technical assistant, United States Public Health Service: QUANTITY AND METHOD OF USE OF PARIS GREEN. " Baris green in antianopheline work should be diluted with a large proportion of inert dust. Only very small doses are necessary to poison larva?, and the dilution enables one to spread a relatively No. 3. 541 DIVISION OF PREVENTIVE MEDICINE. small quantity of the poison over a large surface. Further, any risk of poisoning the operator or the water treated is minimized by the use of the diluted dust. As a diluent we have successfully used fine sand, rotton-wood dust, and road dust. Road dust, preferably mixed with some fine clay, seems to be as effective as any. The addi tion of weight in the form of some coarser sand is helpful in enabling one to direct the dispersal of the lighter dust. Some of the diluting dust sinks on contact with the water, but most of the arsenic is left on the surface. Flowers of sulphur has not proved a suitable dilut ing dust, possibly because so large a proportion of it remains float ing that it is ingested with the Paris green, which latter is then too much diluted. A dilution of about 1 part of the poison to 100 parts of the inert dust seems to be a favorable mixture. "The quantity of Paris green to be used must depend somewhat on the character of the breeding place. Where there is much high trass, reeds, and the like, one would use somewhat greater quantities of the poison than where the surface of the water is clear or covered by low surface vegetation only. Since the poison is relatively in expensive, and the danger of poisoning the water of the breeding place is small, quantities somewhat larger than those given in the protocol would seem to be advisable, possibly about 10 c. c. (approxi mately 12 grams, 0.43 ounces avoirdupois, 0.6 cubic inches, or two level teaspoonfuls) to 90 square meters (1,000 square feet). ''A slowly settling cloud of dust carried along by a light wind is apparently the best agent for the distribution of the dust, and the main thing is to start this cloud in the right place and direction. A single cloud may destroy larvso over a wide area and at a consid erable distance from the operator. We have tried certain mechani cal means for distributing the dust, such as the dust-guns used in dusting arsenic on cotton plants, but thus far we have succeeded best by simply throwing the dust into the air by hand. The cloud can thus be formed high or low, to the right or to the left, depending on the force and direction of the wind. The pole and bag method, sometimes used for dusting plants, has been found useful in treating a breeding place at the bottom of a deep ditch. TIME OF DAY FOK THE USE OF THE POWDER. ''The best results are to be expected on a sunny day when the powder is spread after the sun is well up and the dew has disap peared from any vegetation covering the breeding place. FREQUENCY OF TREATMENT. " The frequency of treatment of a breeding place must depend largely on the temperature of the water. In a recent experiment 542 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. anopheline larvae were thoroughly destroyed over a given area. The place was kept under observation from day to day, and frequent collections of larvae were made. Eleven days after treatment fully grown larvae and a few pupae were found. In this breeding place, then, it would have been necessary to repeat the treatment within ten days. The weather was warm, and the temperature of the water very high, and it is probable that in this pond the growth of the larvae (larvae of A. quadriniaculatus) was nearly at its maximum rate. COST. " Paris green was recently quoted at 22 cents per pound, f. o. b. New York City, packed in 300-pound barrels. Small quantities may be purchased in drug stores for $1 per pound. At 25 cents per pound the amount sufficient for at least 1,000 square feet, 10 c. c, would cost about seven-tenths of a cent. The calcium arsenate in com mon use for dusting cotton plants may be purchased for about 15 to 20 cents per pound. The use of a powder instead of a liquid should greatly lower the cost of transportation. Usually a dust suitable for dilution can be found in the neighborhood of the breeding place, so that one has to transport only a pound or so of Paris green for the treatment of a large area. DANGER OF POISONING THE OPERATOR OR THE WATER TREATED. " The danger to persons engaged in distributing arsenic-contain ing dusts as larvicides would seem to be mainly through the possibility of inhalation of the poison or its absorption through the skin rather than through ingestion. In our search for information regarding the possible harm to men or domestic animals engaged in distributing arsenical dusts as insecticides, we sent letters of inquiry to 17 United States or State agricultural experiment stations in the cotton or tobacco growing States, in the hope that information might be ob tained from those who have had much practical experience with these dusts and their possible harmful effects. In some States these arsenical dusts, calcium arsenate in particular, have been used by the ton in combating the boll weevil. Of the 16 stations replying to our inquiry 14 of the correspondents had had experience in the use of arsenical dusts. Of these 14 about half had knowledge of some injury to man or domestic animals through the use of these arsenical dusts. The lesions reported were chiefly of the acute type and of a minor degree, such as sores on exposed parts of the body, irritation of the bronchial tubes, and sometimes intestinal disorders—lesions which usually healed promptly. Some more serious cases of chronic poisoning were reported to us by Mr. B. R. Coad, in charge of the Delta Laboratory, United States Bureau of Entomology, at Tallulah, La., who kindly wrote us a full description of these cases. The No. 3. 543 DIVISION OF PREVENTIVE MEDICINE. cases were of the cumulative type of poisoning, and occurred ex clusively among persons who had worked with the dusts in close quarters for several years. They occurred as the result of exposure to calcium arsenate as well as to other kinds of arsenical dusts. ' The chronic types of poisoning are practically always accompanied by some dermatic disorder, the injury of which varies widely with the individual, . and is somewhat recurrent. Furthermore, in extreme cases we find neuritis and occasionally some fairly pronounced heart symptoms. It has proved a very obnoxious ailment, and, further more, a very stubborn one. Apparently it is brought about by a saturation of the system with arsenic, and the victim is nearly always hypersensitive to arsenic exposure. In the case of constant exposure the mucous membranes of the nose and throat reach such a condition that they are exceedingly sensitive to mechanical irritation by any form of dust, and a slight exposure to dust brings on an attack which very closely resembles hay fever.' "It is to be remembered that these chronic cases followed a long and intimate exposure to arsenic dusts. Mr. Coad was of the opin ion that the amount of exposure incident to the antianopheline work we have described would probably not lead to any particular danger. It is significant that so little trouble is reported by e±- periment-station workers and by other persons who have used arsenic dusts extensively for some years. Possibly their immunity has been due in part to the fact that they use principally the slightly water-soluble calcium arsenate, and that cotton-plant dust ing extends over a comparatively short period each year. How ever, in antianopheline work where such small quantities of highly diluted Paris green are used, and where the work is wholly out of doors, simple precautions should suffice to protect the user, nor would a health officer anticipate any strenuous objections from the people of a community to the use of a substance so commonly em ployed as an insecticide. "In our experiments we have used no precautions other than to stand to the windward of the dust cloud—the place where one would naturally stand in distributing the dust— and we have experienced no harmful results whatever. However, even with the small quan tities used in larvicide work, it is well to remember that one is work ing with a poison and that some precautions should be taken at least until the matter is further investigated. It is probably suffi cient to keep to the windward of the dust clouds and to avoid in haling the dust as far as possible. In case a great deal of exposure is necessary, one should use some precaution to keep any large amount of Paris green from entering the clothing or accumulating anywhere on the skin. 544 DIVISION OF PREVENTIVE MEDICINE. Vol. XVII. " As regards the danger of poisoning the water treated, it should be emphasized that only a minute quantity of Paris green is dusted over a very large surface, and of that compound only a very small fraction is water-soluble. We have never observed any effect of the poison on culicine larva; or on any aquatic insect or animal, however delicate, other than the surface-feeding anopheline larvae. In particular, we have never observed any indication of harm to top-feeding minnows or to any other natural enemy of larva?. The danger to domestic animals through drinking treated water seems very remote. In order to meet any objections on the part of the owner of a breeding place, one might arrange to have the stock removed from the breeding place for a day or so, but the owner will hardly insist on this precaution when it is- explained to him that the powder is the same as that commonly used against insects and that only a very small quantity of it is to be used on a large body of water. " In sum, the possible advantages of arsenic dust used against anopheline larvae are its cheapness, portability, ease of distribution by means of the wind, and the possibility of using it over areas difficult of treatment by methods now in use. The chief disad vantage is that its use is limited to anopheline larvae—ova and pupae of all kinds, and culicine larvae are apparently unaffected. It is believed, however, that this method will have a place in anti malarial work, especially in places not easily drained and so covered by vegetation or other obstacles as to render them inaccessible to natural enemies of larvae, or to other methods of treatment." CHLOROPICRIN AS SHIP FUMIGANT. The following is an extract from The Nation's Health of July 15, 1922 : " Sulphur dioxid is the aeon-old standby in ship fumigation. It is a fairly good agent of deratization; accidents to human beings very seldom follow its use; it is relatively cheap; it requires very little apparatus to use; highly skilled labor is not absolutely neces sary in its application. On the other hand, its diffusibility is not good; its weight sometimes makes post fumigation aeration some what slow; it is destructive to colors and tarnishes or even corrodes certain metals. "Carbon monoxid is of considerable value; it is fairly efficacious for killing small mammals; it is fairly cheap; it is not destructive; there is no danger from fire during its use, as with sulphur dioxid: it is light and aeration is easy following its use. A special appa ratus and skilled operatives are required for its use; it diffusibility No. 3. DIVISION OF PREVENTIVE MEDICINE. 545 is not uniform and is uncertain; in the presence of a humid atmos phere it is apt to cause sweating of painted surfaces ; it is ordorless, tasteless, nonirritant, and invisible, and has therefore the great hazard that someone may walk into it and be killed. "Hydrocyanic acid gas is an extremely valuable fumigant; it is highly lethal for mammals, many insects, and all birds; it is highly diffusible, relatively cheap, and not destructive. Skilled and de pendable labor is required for its use ; aeration must be perfect before the fumigated compartments may be entered. It is a useful but highly dangerous weapon in the armentarium of the sanitarian. "An attempt was made by Seguy F. (Arch, de Med. et de Pharm., Nav.. 1921. HI, No. 6, p. 509 et seq.) to utilize chloropicrin in the proportion of 5 c. c. per cubic meter as a deratizing fumigant for ships. The chemical formula of chloropicrin is CC13N02 and is made by the action of calcium hypochlorite on calcium picrate. It boils at 111.9° C, freezes at —0.602° C, and has a density of 1.648 at 25° C. It is an intense lachrymant. For a ship of 4,000 cubic meters capacity (about 1,500 registry tons) 20 liters, at a total cost of 280 francs (about $50 gold), were required. The agent killed all rats and bugs, but 24 hours' aeration was necessary. The difficulty of removal of the gas by ordinary ventilation methods interposes an almost insuperable obstacle by reason of the time element involved. This gas is relatively safe, however, because no one will walk very far into it." INSTRUCTIONS TO MEDICAL OFFICERS. Circular letter, serial No. 198—1922.

The granting of so-called " sick leave " referred to in the attached papers and in the several references was primarily for the convenience of the Government while the Navy, including the Marine Corps, was expanded much beyond the available naval hospital facilities. By sending selected cases to their homes for the period of convalescence, the bureau was able to release beds for more serious cases, and to avoid rental of beds in civilian hospitals ; it was also granted, secondarily, for the purpose of hastening convalescence through change of environment. 2. The scope of this authority was further extended to include the sick attached to naval vessels by the department's letter to the Bureau of Naviga tion (ref. d) of October 30, 1919. 3. This bureau concurs with the Bureau of Supplies and Accounts in the opinion that the practice in question should be terminated, but suggests that 646—22 12 548 vol. xvir.

To avoid complications, directions should be given that no further so- called sick leaves, as mentioned, may be granted ; that leaves already granted may not be extended ; but that leaves now in force may be completed. 5. If authorized by the department, the bureau will issue instructions to the above effect to all naval hospitals, only. E. R. Stitt. Circular letter, serial No. 201—1922. YVJCA:ESK. 132687-0(73).

An explanation has been offered by Morley, the well-known anthropologist, to the effect that this migration was due to the exhaustion of the soil around their cities and villages so that corn could not be raised. While this seems the most reasonable explanation, it does not prove that diseases in the area may not have been a contributing cause. However this may be, we feel pretty sure „that Columbus found the disease waiting for him on his arrival, and it is believed that the disease was first introduced among white men in Santo Domingo." (2) Hirsch (1) credits the accounts of Dutertre ("Hist, gener. des Antilles Franc," Paris, 1667) as describing the first authentic epi demic of yellow fever, occurring in Guadeloupe in 1635. This epidemic lasted off and on until the year 1649; it did not reappear again until 1699. According to Ligon (3) (History of Barbadoes, London, 1657) the disease occurred in epidemic form in Barbadoes in 1647. He states that the inhabitants of the island and shipping too were so grievously visited with the plague (or as "killing a disease"), that before a month had expired after his arrival the living were hardly able to bury the dead. The disease then dis appeared for 43 years, and when it recurred in 1690 it was at first not recognized as being the same disease which devastated the island of 1647. (4) Through his chronological survey of the epidemics of yellow fever in the West Indies, North America, Central America, and the Mexi can Gulf coast of South America, Hirsch shows how the disease was imported from place to place and how it disappeared in certain islands to recur again after a few years, until nearly the entire Caribbean littoral could be included in the endemic area of the dis ease. Various seaports on the Atlantic coast of the United States were visited at frequent intervals. According to Hirsch, only two epidemics that may be designated with certainty as yellow fever had been observed on South Ameri can soil up to the year 1850. Both of these happened at Guayaquil, the first in 1740, concerning which an importation of the disease from outside is expressly mentioned ; and the second in 1842, which can in like manner be proved to have been introduced by strangers who had come from New Orleans by way of Panama. Paraja (5), apparently unaware of Hirsch's reference to the epidemic in 1740, states that not even a tradition exists to cause the disease to be suspected. According to him the epidemic of 1842 caused " a mor tality more or less unbelievable if one relies upon lay historians." The general outbreak of yellow fever in Brazil dates from the end of 1849, when the disease appeared in Bahia, having been im ported either fram New Orleans or Habana. (1) No. 4. 557 PETERSON YELLOW FETOR. ST. THOMAS. Dr. John Bard of New York gives the first available record of the existence of a possible epidemic in St. Thomas. He had heard from the " ancient inhabitants " of New York that so long ago as the year 1702 a malignant fever, little inferior to plague, was imported, which from its extreme mortality was distinguished by the name of "the great sickness." Doctor Bard adds: "The formidable dis ease, if tradition says true, was brought here (New York) from St. Thomas in a single bale of cotton." (3) The first authentic report of yellow fever in St. Thomas dates back to 1793. This epidemic lasted to 1795. The disease then reappeared again in 1816-1818, 1825, 1833, and 1852-53. During the latter two years the disease became very prevalent throughout the Antilles, and St. Thomas has the questionable distinction of having been the start ing point of this epidemic. (1) From 1852 on. there are certain records available in St. Thomas which give us a distinct idea how devastating the disease was, espe cially to the shipping and to the military garrison. The records are those kept by the cemetery authorities and consist of two large volumes in which the name of every person buried in St. Thomas appears; age, sex, birthplace, cause of death, and plot in cemetery where buried are also given. A striking fact in reviewing these records is that nearly every person who died from yellow fever was attached to a ship lying in the harbor or was a member of the military garrison. Apparently every country on the globe has some mother's son buried on this rocky peak in the Caribbean. The following tables show the number of persons that died from yellow fever and were buried in St. Thomas from 1852 to 1902, when the last death from this disease occurred : DEATHS FROM YELLOW FEVER IN ST.

Total. 169 103 83 81 209 257 99 84 62 196 260 347 1,950 As stated above, Hirsch gives credence to the opinion that the epidemic of yellow fever that raged over the Antilles in 1852-53 started in St. Thomas. As seen from Table I, the epidemic com menced in August when 17 people died from yellow fever. Of these, 7 were soldiers from the Danish garrison, 3 European residents, and 560 Tol. XVII PETERSON —YELLOW FEVER. the balance sailors from European and American ships lying in the harbor. The first deaths recorded during the month occurred in the gar rison. The death that occurred in February was that of a sailor from the American brig Lady Maxwell. Of the 255 persons who died from yellow fever during 1852, 19 were Danish soldiers, 15 European residents (including the American consul), and 221 Eu ropean and American sailors. This represents the typical toll from this disease. White sailors were the common victims. In January, 1853, a Chinese also died from the disease. From the nature of the disease it seems reasonable to suppose that St. Thomas was an endemic center for yellow fever for the two decades between 1852 and 1872. The break that occurred during 1861, 1862, and 1863 may represent years when the disease was actually absent from St. Thomas, but amongst the 9 cases that died in 1861, at least 1 was a European resident of the island. The 4 cases in 1863 were all sailors from ships in the harbor that may have been infected at other ports. ,But amongst the first cases that died in 1864 some were residents and members of the garrison. Hence it seems that the above break is only apparent and that the disease was actually present. From 1870 yellow fever suddenly ceased to play the important role it had held for the last 20 years in the health conditions of St. Thomas. The death from yellow fever that occurred in 1872 was in a sailor who might have contracted the disease in another port. With re gard to the epidemic in 1878, the " Sanitary report of the Kingdom of Denmark" (6) of that year states: "This disease (yellow fever), which previously had been present in the island for a number of years, has not shown itself since March, 1870; hence for a period of nine years, in spite of the fact that the island is in steady communication with two of the most important foci of the disease, Rio de Janeiro and Habana. The disease was introduced into St. Thomas from Habana in July, 1878, and spread during the balance of the year amongst the ships in the harbor and in the garrison; 40 cases in all with 30 deaths. At the same time a continued fever of other than the usual type spread all over the island, with sudden onset resembling that of yellow fever, a short continuous fever-attack followed by a contracted con valescence. The landsphysicus considered this an abortive form of yellow fever." In Table III we find that the year 1878 is credited with 13 deaths from this disease, whereas the sanitary report of Denmark notes N». 4. 561 PETERSON—YELLOW FEVER. 30 deaths, with 40 cases in all, illustrating the inaccuracy of the statistics during these years. What is of particular interest in the above report is the appearance of an unusual type of fever that spread over the entire island. From the description given one is forced to think of dengue fever. In the sanitary report for 1880 it is stated (6) that the epidemic started in October and ended December 30 and that 25 cases oc curred, with 9 deaths, another discrepancy as compared with Table III. With the exception of 2 children all the attacked were sea men or people recently arrived. From the report for 1881 (6) we find that 23 cases of yellow fever occurred and that nearly all were imported. The deaths from yellow fever occurring in 1882 and 1884 were all amongst European sailors. The epidemic of 1885 was confined to the garrison, and all who died were soldiers; the same holds true of those cases that died in 1887. From the year 1884 the records from the cemetery files can be sup plemented with special reports from the King's physician and his assistants, the communal physicians. Thus we find a report by Doctor Wissing for the years 1884-85 covering the yellow fever out break during these years. Doctor Wissing shows how the case that died in August was imported from La Guayra, Venezuela. The patient passed quarantine inspection, but became ill six hours later. •He remained for three days in a hotel in town before his case was brought to the attention of the health authorities. A diagnosis of yellow fever was then made, and the patient was removed to the municipal hospital, where he died. Doctor Wissing states that no other case developed from this one. The epidemic that occurred in the latter part of 1884 and during the first half of 1885 was undoubtedly caused by the importation of a case on a French steamer. This case was a stowaway and escaped quarantine inspection. A few hours after landing he became very sick and was removed to the marine hospital. The following morning he presented the typical symptoms of yellow fever, includ ing black vomit. Investigation showed that he had undoubtedly received his infection in Habana. Seventeen days later a Dane con nected with the harbor master's office contracted the disease and died. In December 2 cases occurred on a sailing vessel lying in the harbor. The 2 were removed to the hospital, where they both died. During this month another case occurred in town who gave history of having just returned from Habana. In January, 1885. the local epidemic started in earnest. The first case occurred in the Government house and was soon followed by a number of cases in the barracks. In this latter place 26 cases oc 562 Vol. XVII PETERSON —YELLOW FEVER. curred during the year, with 15 deaths. In August and December 4 more deaths occurred amongst newly arrived Europeans. During 1885, 32 cases in all were reported, with 19 deaths. At the proposal of the King's physician, Doctor Magens, a yellow fever commission was appointed by the Government to study the yellow fever situation at the barracks. This commission found that the shore bed to the east of the barracks, where all kinds of debris, both from town and barracks, were gathered, undoubtedly was the cause of the epidemic. The commission recommended "that the shore line be filled up with good material." In the meantime the soldiers were removed to the country and the barracks thoroughly disinfected. Doctor Wissing, one of the communal physicians in St. Thomas at this time, enters into discussion with other physicians of the Danish Islands with regard to the spontaneous occurrence of the disease. Doctor Wissing is of the opinion that yellow fever can not occur spontaneously after it has been absent for a number of years, but that its reoccurrence is due to importation. Doctor Br0nsted, of St. Croix, declared that yellow fever could occur spontaneously in the West Indies in general, but that St. Thomas was an exception. Wissing rightly calls attention to the falsity of such argument. "That a disease can occur spontaneously in one place and must be imported in order to occur at another is on the face of it without meaning." Magens, of St. Thomas, believed that yellow fever might occur spontaneously in the harbor, although importation might play some role. Wissing states : " It is a fact that a fatal case of yellow fever was imported here in the latter part of 1884 and that a small epidemic started right after; until the mentioned importation there had not been yellow fever in St. Thomas for a number of years, and I consider it a powerful and solid argument for its not being endemic that it does not occur at all for a number of years and then suddenly occurs after a known importation." Doctor Calmer, however, from his study of yellow fever statistics in St. Croix, concluded one should be careful in drawing conclusions from the apparent long intervals of freedom from }rellow fever that, as is well known, occurred in nearly all of the West Indian Islands. Wissing did not believe that Calmer's statistics were very conclusive on account of the uncertainty of the diagnosis. On the other hand. Wissing states that in an endemic area, epidemics could occur at times and mild sporadic cases in the intervals. But where the disease occurs only with long free intervals there it is not endemic, but due to importation. " But," Wissing asks, " what does it mean that after the epidemic has ceased, sporadic cases may appear for several months with quite long intervals between each case?" He compares this with a measles No. 4. 563 PETERSON YELLOW FEVER. epidemic in Copenhagen. " The epidemic starts, it grows until the culmination has been reached, it subsides week after week ; fewer and fewer cases occur until a few sporadic cases spring up here and there, when the epidemic is finally stopped." Yellow fever reappeared in St. Croix in 1885, after that island had been free from the disease for six years. Wissing can not agree with the opinion expressed that the disease appeared spontaneously on that island when it was in direct communication with St. Thomas where yellow fever was known to exist during 1885. During 1886 no case of yellow fever was officially reported. In 1887 we find an argument between the communal and the quarantine physicians as to the presence of yellow fever. The quarantine officer reported 2 cases of the disease in two soldiers that had been placed as guards on board two ships that had arrived from smallpox-infected ports. The first one was feeling somewhat indis posed before he went on this duty, and two days later was taken seriously ill with symptoms of remittent fever. He was placed in the hospital, where he developed symptoms of high fever, bloody vomit, albuminuria, and yellow discoloration of the skin and later died. The second case was taken sick four days after having been placed on guard on another ship. This patient also died with typical symptoms of yellow fever. A third case also developed under similar circumstances. He recovered, however. He developed the same symptoms as the others except black vomiting. The communal physician considered these cases as bilious remittent fever. From a study of the symptoms it seems, however, that the quarantine officer was right. No cases of yellow fever were officially reported during 1888 and 1889. In 1890 we find a new landsphysicus in St. Thomas. In his annual report for that year he says in part : " During the summer 7 cases of yellow fever occurred. The first case occurred in the early part of June, the second in the latter part of July, the third and fourth in the first part of September, and 3 in the first part of Octo ber. In order not to harm the islands without sufficient cause— through possible isolation and quarantine—these cases were officially reported as pernicious remittent fever. This was considered to be so much more permissible as the cases were more or less sporadic and the disease did not appear as an epidemic. Any importation of the dis ease could not be proven, and it is also commonly considered that this disease can occur anywhere in the West Indies spontaneously. " Six cases were in young European adults who had been only a short time in the West Indies. These all died. The seventh case occurred in an 8-year-old boy who had been born in St. Thomas but who had recently returned from a long visit to Denmark. This boy recovered. 564 Vol. XVII PETERSON YELLOW FEVEE. "Any connection between the above cases could not be shown; the disease attacked young Europeans of different nationalities in different positions and residing in different places. A long time, sometimes over a month, passed between the development of the various cases." In addition to the above cases, three deaths from yellow fever occurred amongst the soldiers at the barracks. This epidemic is of peculiar interest from many standpoints. The landsphysicus failed to find any proof that the disease was imported. The mortality was extremely high. Cases occurred in the barracks, and in widely separated localities. Two explanations can be given. The disease was still endemic in St. Thomas in spite of the fact that no cases were officially recognized during 1888 and 1889. This explanation finds some support when we recall the argumentation over the cases in 1887, and is, of course, also supported by the fact that importa tion could not be shown. The other explanation is that importation of the disease had taken place without the authorities being able to demonstrate it. From 1891 on, no case was officially recognized as yellow fever. We find, however, that during 1896 two cases were imported through the shipping. These cases died. During 1897 the landsphysicus states, in his annual report, that intermittent and remittent fevers increased and that the remittent type of malignant character was not so rare. He states, however, that no case of yellow fever oc curred during this year. In the report for the year 1901 we find that no distinct case of yellow fever occurred but that "the Stegomyia mosquito, which lately has been pointed out by American and Cuban physicians to be the vector of yellow fever contagion, is very com mon in St. Thomas as well as in the other West Indian Islands." In the report for the year 1902, the landsphysicus, Dr. P. Mor- tensen, pays a glowing tribute to the work of the American physi cians in the West Indies. He says in part : " The Americans have had wonderful success in fighting smallpox in Porto Rico. But still more credit is due them on account of the excellent manner in which they are fighting yellow fever in Porto Rico as well as in Cuba. During the reign of Spain over these islands they were a continuous source of danger to the whole West Indies ; yellow fever was always present, and every so often it occurred in severe epidemic form, especially in Habana. The United States has certainly done an herculean job in cleaning out this Augean stable, but it has been done, and the United States can refer with pride to the results that have been accomplished. . . . " The Americans have succeeded in a few years in practically stamping out yellow fever both in Porto Rico and in Cuba. This has also been a great help to the Danish Islands, and St. Thomas No. 4. 565 PETERSON —YELLOW FEVER. has learned a lot from this work. There are still some sources of yellow fever in Mexico and Colombia, but they are farther away and are not so dangerous to St. Thomas as were those of Porto Rico and Cuba in Spanish times." In the above report it is also stated that no distinct case of yellow fever occurred in St. Thomas during 1902, although a young Danish officer attached to the local barracks succumbed to a dis ease very much resembling yellow fever. The landsphysicus was of the opinion that it was a typical case of yellow fever. (7) During this year we also find that three cases of " pernicious malaria," resulting in death, were imported through the shipping. From 1903 on it is very difficult to show that any yellow fever occurred in St. Thomas. From this time the deatli rate from inter mittent and remittent fevers also rapidly declined, and the formidable figures which represented these diseases in the death tables became overshadowed by those representing deaths from gastrointestinal infections. The deaths from such conditions as intermittent and remittent fevers undoubtedly were closely associated with the yellow fever situation. We find, however, that these fevers grow less and less in number as the sanitation of the city improves. The Danes built a complete system of surface drainage in the city proper, and the influence of this improvement is readily seen in the marked reduc tion of deaths from malarial fevers. The latter condition ceased to be an urban factor and became a rural one, still, however, affecting the suburbs of the town. SPONTANEOUS ELIMINATION OF YELLOW FEVER. The one fact that stands out clearly is that yellow fever has dis appeared from St. Thomas without any attempt on the part of the island to eradicate its mosquitoes. As a matter of fact, the disease had practically disappeared from St. Thomas before Finley's theory of mosquito transmission had been proven. History tells us that many of the West Indian ports were free from yellow fever for long periods of time. Epidemics occurred and died out, and years later recurred. There is no doubt about the fact that the recurrence of the disease after these years of freedom was due to reinfection of the community from without. H. R. Car ter (8), that master in tropical sanitation, has given us a mechanism of the spontaneous elimination of yellow fever from endemic cen ters, which not only gives the reason for this elimination, but also shows that the conception of a world free from yellow fever is a practical one and needs only a few helping strokes from the sani tarian before it is an accomplished fact. 4530—22 2 566 Vol. XVII PETERSON —YELLOW FEVER. Let us follow Carter in his logical argumentations and deductions. " In endemic centers it is not necessary to exterminate Stegomyia to eliminate yellow fever. If the number of mosquitoes be brought below the ' critical number ' for yellow fever, at that place the dis ease will die out. Note, too, that this critical number for any place will vary directly as the proportion of men immune to yellow fever is to the total population. " Thus, if with 100 cases of yellow fever introduced into a com munity in which all were susceptible to yellow fever, the number of Stegomyia were such that exactly 100 men would be infected from them, the disease would neither die out nor increase. This would be the critical number of Stegomyia for that place and time. With fewer mosquitoes than this, less than 100 men would be infected and the fever would die out. If more, it would increase. Now, if one-quarter of the .inhabitants are immune to yellow fever, obvi ously the same number of mosquitoes which infected 100 men before would now infect only 75—one-quarter of their bites going to immunes and hence wasted —and the disease would die out. The number of mosquitoes required to infect 100 more men, and hence perpetuate the fever, would have to be increased by one-third above the first number. " Obviously, then, this critical number, below which the Stego myia must be brought to eliminate fever, is less in a town as the proportion of susceptible people increases, and more intensive work is required to eliminate it from such a community, other things being equal, than from one in which a large proportion of the population is immune." We know that yellow fever has disappeared from such places as Georgetown, Demarara, Port au Prince, Santo Domingo, and St. Thomas without any effort on the part of these communities to lower the mosquito index. But, as Carter states, nonreport of yel low fever does not of itself imply its nonexistence. If a number of nonimmunes are introduced into a supposedly yellow-fever free city and the disease develops amongst them, this is positive proof that yellow fever existed there. On the other hand, if intimate contact was kept up between these nonimmunes and the natives for a long time and no yellow fever developed, it may be deduced from our present knowledge of the disease that it did not at the time exist there. This practical test has been applied to nearly all of the above towns. Let us now consider Carter's mechanism of spontaneous elimi nation of yellow fever in a little more detail. It is assumed that one attack of yellow fever usually gives, a permanent immunity. The endemicity of yellow fever in a certain Xo. 4. 567 PETERSON —YELLOW FEVER. area depends on three factors for its continued existence : Parasites (in mosquitoes and men), active mosquitoes (Aedes calopus), and susceptible men. These factors should all be present at the same time and the insects have access to both infected and susceptible people. If for any reason any one of these factors disappears or ceases to function, yellow fever can no longer exist. According to our present knowledge of the disease, the parasites of yellow fever exist only in the infected mosquitoes and in infected people. The life of a mosquito in nature is compartively short— hence also the life of the harbored parasites. Man serves as a res ervoir only for a short time. If the third factor, susceptible men, is not present at the same time and place as the infected mosquito, yellow fever will have no chance to spread, but will disappear. Susceptible people may be supplied in two ways: Immigration (shipping) and births. " Both classes effect continuance of yellow fever, and theoretically either one may be sufficient to continue it. Yet the proportional effect of the introduction of an adult and the birth of a baby in keeping up the infection is very different. That of an adult immigrant is very much the greater, so that to supply the people necessary to keep up yellow fever, it requires a very much larger number of babies to be born than of susceptible adult immigrants. In proportion to their number then, adult immi grants are of far more importance in thus keeping up yellow fever than babies, and a town receiving no susceptible immigration needs to be much larger to be a permanent focus of yellow fever than if it did receive such immigration. Indeed Gorgas, in 1916, expressed himself as believing that immigration of susceptible adults was necessary to continue yellow fever . . . that it could not be kept up by the births alone." In St. Thomas the influx of susceptible adults through shipping grew gradually less and less and the new born showed themselves incapable of keeping the endemic alive. Hence, in Carter's words : " If one attack of yellow fever produces in general a permanent immunity, a community will have in time no people susceptible to yellow fever left. Unless there is an intro duction of such people, yellow fever would then disappear; and as soon as the infected mosquitoes died off, the parasites would dis appear and the community be free from infection. Indeed, yellow fever would doubtless disappear before there were 1 no people sus ceptible to yellow fever left,' because, under the doctrine of chances, there would be no susceptible people left, fulfilling the conditions of time and place mentioned above, before there were absolutely none at all —possibly long before." Carter calls this mechanism the " fail ure of the human host." 568 Vol. XVII PETERSON —YELLOW FEVER. REINFECTION OF A COMMUNITY. Once a community has freed itself of yellow fever by failure of the human host, it will remain free forever, unless the same three factors for conveyance are again brought together. Because the mosquitoes are a constant factor — always breeding to the limit—the next ap pearance of the disease would depend on the influx of susceptible people and the introduction of parasites. A community which for some reason or other has lost its impor tance as a shipping center and whose immigration is practically nil will not become susceptible to a yellow-fever epidemic until the new born have increased in number and grown up to become one of the deciding factors. The number must be large enough in order that the conditions of time and place be fulfilled when the parasite is finally introduced. In order to keep the disease out, isolation from infected places is necessary. " The community that has eliminated yellow fever through the con trol of the insect host does not need to isolate itself from infected places as long as this control continues to be efficient, because, with control of the insect host, yellow fever is not communicable, and such parasites as are brought in by infected men or infected mosquitoes would, at the most, establish a very temporary focus of infection. If the control were complete, infected men would transmit no parasites. It is to be noted, however, that the reduction of Stegomyia sufficient to eliminate yellow fever from a town in the Tropics would nearly always be less than that required some years later to prevent its spread, because there will then be a larger proportion of susceptible people than at first. Hence the mosquito control must be more in tensive." (8) Carter gives the following factors as responsible for the great diminution of yellow fever which has been going on since the decline of the tropical sugar industry and which is still in progress. "(1) Diminished immigration to the Caribbean littoral due to diminished trade and commercial importance of this area. "(2) The substitution of steam for sailing vessels has enormously lessened the number of infections carried between ports, thus lessen ing the reinfection of such ports which had cleared themselves of yellow fever. Sailing vessels— Frequently carried stegomyia as well as infected men. Longer in port. Larger crews per unit of carrying capacity. Laxer discipline. Iron steam vessels— Rarely carry stegomyia. Less long in port. Smaller crews. More strict discipline. No. 4. 569 PETERSON YELLOW FEVER. "(3) Diminished strategic importance of the Caribbean Sea and the practical withdrawal of European fleets and garrisons, thus lessening the number of susceptible people. "(4) The extinction of the great permanent foci at Habana, Panama, and Rio. "This enabled such ports on the Caribbean especially as could spontaneously free themselves of yellow fever to remain free—be ing no longer exposed to reinfection, or rather much less so exposed. "(5) The European war has both restricted foreign immigration and caused commercial depression." In surveying the death tables from yellow fever in St. Thomas we find epidemic outbreaks of the disease nearly every year from 1852 to 1871. From 1872 to 1891 we find many years without deaths, some years with a few deaths amongst sailors (Imported cases) , and a few years with small epidemics. The general tendency of the disease to disappear is clearly seen. Between 1892 and 1901 only two deaths occurred, and these were imported cases, apparently not followed by any secondary ones. It is difficult to believe that the death from yellow fever recorded in 1902 actually was a case of this disease. From our present knowledge of the epidemiological features of yellow fever it seems that a case occurring in a member of the garrison would be fol lowed by other cases, as we have here a number of susceptible people concentrated in one building (the mosquito always being present). From 1902 on not even a suspicion of the disease being present in St. Thomas has been noted. In analyzing the factors having bearing on this spontaneous elim ination of the disease from St. Thomas we find that it occurred before the method of transmission of the disease was known and hence could not have been influenced by any sanitary measures.1 Due to the marked decline in shipping and lessened immigration the number of susceptible people was brought below the "critical number" and hence by " failure of the human host" the disease dis appeared. By elimination of the disease from Habana and other ports through control of the insect vector, chances for reinfection of St. Thomas were rendered more remote. The importance of clearing up great permanent foci of infection and its influence on the smaller foci was realized by the Gorgas com mission of the International Health Board when they, in a world survey for endemic yellow fever centers, reported that this disease could be "eradicated from the west coast of South America by 'Acdes calopus (Meigen) has been a constant factor In St. Thomas — breeding to the limit. Mosquito eradication was not attempted until a few years ago when the United States took over the islands. Since that time the progress of mosquito eradication has steadily, although slowly, gone forward step by step. 570 BUNKER—KIDNEY FUNCTION. Vol. XVII * eradicating it at Guayaquil, Ecuador." The truth of this state ment has practically been realized. The soundness of Carter's view with regard to the mechanism of spontaneous elimination of yellow fever is further seen on the west coast of Africa. The yellow fever commission, headed by General Gorgas and after his untimely death by General Noble, which was sent under the auspices of the International Health Board to study the yellow fever situation on the west coast of Africa, found no trace of a yellow fever epidemic in spite of the fact that Aedes calopus was present all over. The old idea that an extended area of endemic pestilence must exist or that the whole area of West Africa must represent such a pestilence district must be discarded in the face of the find ings of the commission. The same reasons may be given for this dis- nppearance as have been given above— lessened shipping, substitution of steam for sail, clearing up of West Indian foci, and, finally, the " failure of the human host." The proof that yellow fever has disappeared from this coast was furnished during the World War, when large bodies of white troops were introduced without the occurrence of any epidemic. REFERENCES.

Bcnker, Meutenant Commander, Medical Corps, United States Navy. Kidney function deals with the ability of the kidney to excrete substances from the blood stream —a process usually accompanied by concentration, especially in the case of what we consider to be waste products (urea, uric acid, etc.). Concentration here means that the No. 4. BUNKER KIDNEY FUNCTION. 571 I percentage strength of the substance is greater in the urine than in the blood. It would appear that, in addition to the secretory (or excretory) function, the kidneys have also an active synthetic func tion. Nash and Benedict have presented strong evidence to the effect that the ammonia in blood and urine is the result of the latter. The efficiency of the kidneys is frequently affected by disease, especially such as disturbs the kidney, and is also usually diminished after the age of 50 years as the result of senile changes. It can not he too strongly emphasized, however, that disease of the kidney does not necessarily imply an inability (either partial or complete) to eliminate substances —anatomical need not parallel functional lesion. Function may be normal, with organic changes present, especially if they are focal in nature. So, disease of the kidneys is not synony mous with impaired kidney function. Even less definitely is the latter condition established by the finding of albuminuria with or without cylinduria. Renal insufficiency does not affect the excretion of all compounds to the same extent. It is well known that the functions for chlo rides and for urea are independent of each other. Uric acid may be retained in the blood while the excretion of other nitrogenous sub stances is apparently normal. In any urine examination, then, one should bear in mind the possible effect of an impaired excretory power relative only to the substance under consideration. From ex perience, we may estimate the probable effect upon excretion of other substances, but as yet no hard and fast comparisons can be drawn. To advancing uric-acid retention is usually added that of urea, and later of creatinine. But in gout (where the increase of blood uric acid is believed to be the result of retention) the uric acid alone is retained, even when it may exceed by far that which would be accom- ' panied by retention of other substances in nephritis. And our ex perience also leads us to expect, with a marked general retention of nitrogenous compounds, that certain other substances (sugar, cholesterin, diastase, etc.) will be retained. As the preceding would suggest, the usual result of impaired kid ney function is retention in the blood stream of material that is normally secreted into the urine. The other side of the- picture is a diminution of such material in the urine unless the kidneys work overtime. This they will do, but a continued effort of such nature aggravates the condition and, sooner or later, exhaustion will resvdt. Such is the sequence of events in uremia, in which one finds the amounts of nonprotein nitrogenous compounds increased in the blood and decreased in the urine. It is well to bear in mind this complementary nature of urine and blood examinations. The functional variation from normal may, however, be evi denced by an increased permeability of the kidneys. In such a 572 BUNKER—KIDNEY FUNCTION. • Vol. XVII case, depletion would be the result, as happens occasionally in chronic diffuse nephritis when one finds low values for the blood urea. And, finally, the alteration that disease may produce in the ammonia function noted above must not be overlooked, as it has an important protective duty in the acidosis of certain diseases. I have considered this more fully in a separate article on acid-base equilibrium. In this connection, we speak of the kidney " threshold " for a substance, i. e., the concentration required in the blood stream before the kidney will excrete it, at least in abnormal amount. For chlo rides, this is quite definite at 562 milligrams per 100 mils of blood plasma; for sugar, it lies at about 160-180 milligrams per 100 mils of whole blood, and if such concentration be passed, then glycuresis occurs until the blood sugar is normal. The threshold is not neces sarily absolute, but simply indicates that, with less sugar, for in stance, only the normal traces are passed. Chloride excretion begins only when their concentration passes the threshold value, and the rate of their elimination depends upon their excess. Other com pounds, such as urea, for example, may have no definite threshold value. Disease may affect the value, either by raising it and causing abnormal retention, or by lowering it and giving rise to depletion. The threshold for sugar rises with advancing age ; up to a value of 200 milligrams of sugar per 100 mils of blood, diuresis will lower it. In diabetes mellitus, the sugar threshold may rise to 200 per cent or more of the normal. Some consider that renal diabetes is the re sult of a lowered threshold for sugar. The thoughtful practitioner of medicine is interested in kidney function for several reasons. It is frequently affected in disease, and the timely recognition of impairment enables one to guard against serious consequences, such as uremia. Chemical analysis of the blood indicates the metabolic substances affected, and guides in the adjustment and regulation of diet, habits, etc. We have men tioned the connection with acidosis. The status of kidney function having been established, one can more intelligently interpret the results of urine examination. And, before accepting a normal find ing, one should be satisfied that one kidney has not taken upon itself the work of a badly crippled partner. Lastly, remember that a normal function does not exclude a diseased kidney. Renal function and acidosis enter prominently into the question of operative risk. The former is especially material in genito urinary surgery, notably in the average prostatectomy. A few days' drainage of the bladder may alleviate a renal insufficiency due to obstruction or infective processes in the lower genito-urinary tract. Failing so to do, the patient is not a good surgical risk, as then the No. 4. 573 BUNKER—KIDNEY FUNCTION. impairment is probably due to the kidney itself. Frank states that, from a standpoint of renal function, a patient is not in the best pos sible condition to undergo any surgical procedure if he has a phenol- sulphonephthalein excretion of less than 40 per cent (unless due to disease of other organs, especially the liver), an Ambard coefficient of more than 0.1, and, as^ regards the urine, but little variation in quantity from day to day, fluctuations in specific gravity of less than 0.007 regardless of diet, and a nocturnal polyuria. Others have added a nonprotein nitrogen of the blood of more than 50 milligrams per 100 mils, and, with the phenolsulphonephthalein test, an appear ance time of more than 25 minutes, or less than 20 per cent excretion during the first hour. Many methods are employed for the estimation of renal function, and, in general, they are based upon four principles of procedure. 1. The determination of the degree of retention in the blood of various metabolic products. Here enters chemical analysis of the blood, in the course of which examination is made especially for urea, uric acid, creatinine, nonprotein nitrogen, and chlorides. 2. The determination of the rate of excretion via the urine of a chemical substance that has been injected or ingested in known amount. Such as phenolsulphonephthalein, methylene blue, indigo- carmine, rosaniline, sodium chloride, potassium iodide, salicylic acid, lactose, urea, etc. 3. The comparison in a patient on a known diet between the in gestion and excretion of, as well as the ability of the kidneys to concentrate, a group of substances involved in normal metabolism, viz, water, nitrogen, and sodium chloride. This is Mosenthal's method. 4. The determination of the ratio between the concentration of various metabolic products, especially urea, in the blood and their excretion in the urine, the result being expressed as a ratio of ex cretion, or as a coefficient. This includes the Ambard coefficient, the McLean index, the Austin, Stillman, and Van Slyke formula, etc. The relative value of the different methods is debatable. Probably those least open to criticism are chemical analysis of the blood, the phenolsulphonephthalein test, and Mosenthal's method. The for mulae have many warm advocates as well as severe critics. A rough clinical comparison of the two kidneys may be obtained by deter mining the urea in specimens of urine simultaneously collected by means of the uretheral catheter. Blood chemistry, now that its value has been established, is gen erally given preference and allowed greater weight in case of dis agreement with other tests If treatment brings a high blood urea to normal while the Ambard coefficient remains high, kidney function is probably not impaired. It measures excretory function for normal 574 Vol. XVII BUNKER—KIDNEY FUNCTION. metabolic products, and has the additional value of an aid in prog nosis, especially if the creatinine is increased, in diagnosis, and as a guide to treatment, especially dietetic. It has the disadvantage of a possibly unfamiliar technique, and does not afford a comparison of the two kidneys. The substances usually considered are the nitrogenous compounds (nonprotein nitrogen, urea nitrogen, uric acid, and creatinine), but retention of others (sugar, cholesterin, chlorides, diastase) are also of significance in this connection. Of the nitrogenous constituents, the kidney excretes creatinine most readily, urea next, and uric acid with the most difficulty. It normally concentrates creatinine about a hundred, urea about eighty, and uric acid only about twenty times. As a consequence, an impairment of function results first in the retention of uric acid, then urea, and, finally, creatinine is also re tained. Owing to the relatively small amounts of uric acid and creatinine present, the nonprotein nitrogen, which includes the nitro gen in them as well as in other compounds, is not appreciably affected except by the urea increase. This is the basis of an intelli gent interpretation of the findings. The urea (and therefore the nonprotein nitrogen) are so mark edly affected by diet, especially among nephritics, that judgment must be used when they are employed as indices of renal function. This fact was not properly appreciated until recently, and probably accounts for much of the discredit cast upon chemical analysis of the blood in this connection. The uric acid, being less exogenous in origin, is perhaps the most delicate and the safest index. The in crease appears early, and 3.5 milligrams per 100 mils blood may be considered the high normal value. An increase during a high- purine diet is especially significant, as it does not occur in normal persons. We have found the uric acid determination of much assist ance in judging the significance of occasional casts and traces of albumin in urine—an increase speaking for an organic kidney lesion. On the usual restricted hospital diet, over 20 milligrams urea nitro gen per 100 mils blood should be considered suggestive of impaired renal function; over 75 speaks decisively for renal involvement and probable uremia. Values around 50 demand judgment and a scrutiny of the diet as well as search for other possible causes of unusual protein metabolism. Results of change of diet are usually apparent only after several days. Values for creatinine of over 4 milli grams per 100 mils of blood do not occur without great impairment of renal function and probability of uremia. Phenolmlphonephthdilevn (phtkalein, or red) test. —This was de veloped by Kowntree and Geraghty, and its simplicity makes it very useful, especially to the isolated practitioner with limited laboratory facilities. It estimates only function for a foreign substance, is not No. 4. 575 BUNKER—KIDNEY FUNCTION. considered quite as reliable as chemical analysis of the blood, and, of course, does not give the additional information that the latter sup plies. It is, however, of much value, has no contraindications, and does compare the kidneys when combined with ureteral cathetriza- tion or the use of a separator. The technique of the test can be found in any work that considers clinical laboratory methods. t Impairment of renal function, of course, increases appearance time and lessens the excretion, serious cases not unusually excreting less than 1 per cent during two hours. Positive results are of more significance than negative, and the excretion of the dye is less affected by glomerular than by tubular changes. Values of more than 75 per cent for two hours may be accompanied by diuresis, and Frank con siders such a finding suggestive of renal disturbance with irritation if there is any other corroborative evidence. MosenthaPs test is a refinement of previous work that endeavored to estimate renal function by measuring the ability of the kidneys to concentrate and excrete substances that occur normally in the blood stream (water, chlorides, and nitrogen). As originally promulgated, it involved the use of a definite diet that he now describes as the " high-protein " diet. A " low-protein " diet and the diet normal for the patient were later tested, and he finds that the essential facts held with all. The result has been a simplification of technique that enables wider application, and its use for ambulant cases in ordinary private practice. It was claimed that earlier evidence of renal insufficiency was obtained by this method than by the phthalein test, the Ambard index, or by determination of the blood urea. At 8 a. m., void and discard urine, and eat breakfast. Void and collect urine only at 10 a. m., 12 noon. 2, 4, 7, and 10 p. m., and at 8 a. m. on the following morning, this last sample being the night urine. Eat lunch at 1 p. m. and dinner at 7 p. m. (three hours before last evening collection of urine). The meals are those to which the patient is accustomed, and a record of everything consumed is kept in round figures in order that a basis for criticism of the diet may be at hand. No food or drink is to be taken except at meals. * Determine volume and specific gravity of each sample, and the 24- hour excretion of chlorides (as NaCl) and nitrogen. He avails him self of the inaccuracy of the ordinary hypobromite estimation of urea, and estimates that the results obtained by dividing the urea value thus obtained by 2.14 (the nitrogen factor) is a sufficiently accurate expression of the total nitrogen value for the purposes of the test- As normals, he gives 1.020 (1.018 with tfie "high-protein diet") or over in any specimen as a maximal specific gravity, the extreme values of the different samples to show a variation of 0.000 or more. 576 Vol. XVII BUNKER FUNCTION. KIDNEY : and a night sample of 750 mils or less. By "fixation of specific gravity " is meant a variation between extremes of less than 0.009. A normal maximal specific gravity indicates that the kidney can concentrate the urine satisfactorily, providing the 24-hour amount is adequate. A high specific gravity with oliguria occurs only in pas sive congestion of the kidney, and in acute, subacute, or chronic nephritis, conditions that also show a markedly diminished NaCl excretion, together with considerable albuminuria and edema. Long life is often possible providing a low specific gravity is compensated by polyuria, as in diabetes insipidus and a few cases of chronic nephritis. A high fixed specific gravity (about 1.020) may occur in normal individuals as the result of insufficient fluid intake, or may be the re sult of diseases characterized by edema and oliguria, especially myo cardial insufficiency and acute or chronic nephritis. A low fixed specific gravity is a danger signal and is found in many widely vary ing conditions (diabetes insipidus, chronic nephritis, marked anemia, the elimination of edema, cystitis, pyelitis, polycystic kidney, pros tatic hypertrophy, urethral stricture, paralysis of the bladder as in tabes dorsalis or tumor of the cord, etc.), which may do well as long as there is a compensatory polyuria. A nocturnal polyuria indicates an overworked kidney, and this may result in functional damage. Over 400 mils should be consid ered somewhat suspicious of renal insufficiency. In nephritis, it may be improved by curtailing the food intake. Edema, hypertrophied prostate, and diabetes mellitus should be excluded. It is a graver sign of functional impairment when on a low protein diet, as it may be largely compensatory during a high one. NaCl is being ingested in unnecessary amount if the 24-hour ex cretion exceeds 5 grams. A very low excretion, together with edema, indicates an inadequate elimination, and is then not a criterion of the diet. If 5 or 6 grams of nitrogen are eliminated in the urine every 24 hours there is sufficient protein in the food to maintain the indi vidual's health and strength, provided the diet contains a consider able amount of starch, and restriction of proteins should be guided by the nature of the disease. The test then supplies information useful in diagnosis and prog nosis, an early index of renal function, and a guide to diet. Chemi cal analysis of the blood, especially as to the nitrogenous constituents, will furnish further details as to the manner in which the intake of nitrogenous foods and sodium chloride should be varied. Con clusions should preferably be based upon more than a single test. The underlying idea in the use of formula? is to eliminate any confusion that might arise as the result of changes in the blood No. 4. 577 BUNKER—KIDNEY FUNCTION. concentration of urea due to the level of the general protein metabo lism. They are usually based upon the urea function, but may be derived for other and urinary constituents such as chlorides or sugar. They are criticized mostly because of the use of exact mathe matical formulae for the expression of life processes, and because of disagreement as to what does constitute the law of urea function. Again, it is inconvenient to accurately collect the urine excreted dur ing short periods. In arteriosclerotic conditions and those of car diac decompensation, they are occasionally at fault, and should be checked by other methods, especially blood chemistry. It is doubt ful if they give information that is not supplied by blood chemistry alone. The Ambard coefficient changes before the nonprotein nitro gen of the blood, but they agree closely in later stages. The co efficient has also possibly a greater prognostic significance than the phthalein test. While Ambard has also developed a formula based on the chloride function, the following one relative to the urea function is the more familiar. K is known as Ambard's coefficient; U is grams urea per liter of blood ; C is grams urea per liter urine ; D is grams urea per 24 hours : and Wt is the weight of the individual in kilograms. The normal value is about 0.08 (0.06-0.09) , and indicates either no disease or com pensation. K rises as kidney function is impaired, more than 0.2 indicating severe, and more than 0.3 maximal impairment. A rise is graver with vascular than with chronic diffuse nephritis. Depres sion of the coefficient means increased renal activity due to irritation. The coefficient is said to have a peculiar diagnostic significance with tuberculosis of the kidney, a normal value indicating that only one is affected, while an increased coefficient means that both are affected or that there is a toxic nephritis of the opposed kidney. McLean's index is : The symbols have the same significance as with the Ambard coef ficient. A normal value is 80 to 100. It is lowered in renal insuf ficiency. Values below 50 mean impairment; below 10, marked impairment. The index may be 1 in terminal states. Austin, Stillman, and Van Slyke have corrected what they believe to be erroneous assumptions in Ambard's formula, and suggest, as giving more consistent results, the following: 2T= r WtX U* D 578 Vol. XVU RAYNOR —MEDICAL, CORPS UNITS. 1) is grams urea in 24-hour urine specimen ; B equals grams urea per liter of blood; V is liters of urine per 24 hours; and W is weight of individual in kilograms. The normal value is 7.5±3, and renal insufficiency produces lower values. We can establish the status of renal function in any given case, and are then in a position to intelligently prescribe dietetic and other treatment. The substances affected by a retention are determined, and our aim should then be to adjust diet, etc., in such a manner that the kidneys are able to excrete materials brought to them. Regulate the regimen by the excretory powers of the kidneys, but do not over look the nutritive needs of the body. THE FUNCTIONS AND ORGANIZATION OF MEDICAL CORPS UNITS SERVING WITH THE MARINE CORPS IN THE FIELD. By 8. N. Ratnor, Major, United States Marine Corps. THE MEDICAL REGIMENT, INFANTRY DIVISION (WAR STRENGTH). Like every other branch of the Army, the Medical Department has been completely reorganized since the World War. Old units have been discarded or radically modified and new names adopted, so that modern sanitary tactics presents many phases of a new subject. The general scheme of the new Medical Department field organiza tion is best exemplified in the recently established " medical regi ment." The prescribed methods of this unit in the collection, treat ment, and evacuation of the wounded are followed, with appropriate modifications in every organization of the Army, from the battalion to the base. A study of its workings at this time will greatly facili tate the study of the medical service of the brigade, which will be considered in the next article. The medical regiment is primarily a divisional organization. All of the medical services of the division have been brought together into one unit. The old hospital companies have been assembled as a battalion of the medical regiment; the former ambulance companies now constitute the ambulance battalion, and a new organization called the " sanitary battalion " has been added. In addition to these battalions, the medical regiment includes a headquarters, a service company, a medical supply section, a medical laboratory section, and a veterinary company. The medical regiment is commanded by the division surgeon. The medical regiment, as a divisional unit, occupies an intermediate position between the infantry regiments and the larger medical units in the rear. It transports the wounded to the nearest ambulance sta tion by litter, and from there to the hospital station by ambulance. The hospital station is equipped with beds, operating equipment, and No. 4. 579 RAYNOR —MEDICAL COHPS UNITS. arrangements for treating gassed cases. Facilities are available for fairly extensive medical and surgical treatment, but as a rule only emergency work is performed, as the hospital must not be allowed to become overcrowded, and the interests of the patients are better conserved by transporting them as speedily as possible to the better equipped hospitals in the quiet sectors. On# medical regiment is assigned to each division, one to each corps, and four to an army. The two latter organizations have hospital and transportation facilities in addition to the medical regi ment, but the division does not under normal conditions. A brigade acting alone might have attached to it one sanitary company, one ambulance company, one hospital' company, and addi tional medical personnel from the medical regiment. An outline of the organization of the medical regiment is given below : ORGANIZATION OF THE MEDICAL REGIMENT. (WAR STRENGTH.) Headquarters (division surgeon's office) : 1 colonel (division surgeon). 1 lieutenant colonel (executive officer). G majors— 1 sanitary inspector. 1 orthopedist. 1 urologist. 1 neuro-psychiatrist. 1 dentist. 1 veterinarian. 3 captains or lieutenants (including 1 attached chaplain). 1 warrant officer. 12 enlisted men (attached from service company). Service company: 2 captains or lieutenants. 40 enlisted men. Sanitary battalion : 1 major. 12 captains or lieutenants. 306 enlisted men. Ambulance battalion: 1 major. 7 captains or lieutenants. 177 enlisted men. Hospital battalion : 4 majors. 22 captains or lieutenants (6 dental). 247 enlisted men. 580 Vol. XVII RAYNOR —MEDICAL CORPS UNITS. Medical supply section: 2 captains or lieutenants. 13 enlisted men. Medical laboratory section: 1 major. 1 captain. 7 enlisted men. ' i Veterinary company : 4 captains (1 meat inspector). 70 enlisted men. Making a total for the regiment of 60 officers, 1 warrant officer, and 860 enlisted men. HEADQUARTERS. The headquarters of the medical regiment is divided into two sections, one constituting the office of the division surgeon and the other the headquarters of the regiment. As stated in the previous article, the division surgeon is a member of the staff of the division commander and is also in command of the medical regiment. As senior medical officer he has supervision over all matters pertaining to the public health and as a member of the staff and as commander of the medical regiment he is in charge of the sanitary tactics of the medical troops. A lieutenant colonel is executive officer of the medical regiment. Attached to the division surgeon's office are six specialists having the rank of major, as indicated in the outline of the organization. These officers are the chief advisers of the division surgeon, and each has supervision of the divisional work pertaining to his specialty. THE SANITARY BATTALION. The sanitary battalion is essentially a battalion of litter bearers. The designation "sanitary" is not suitable and probably will be changed. During combat it collects the wounded from the aid sta tions and from the field and carries them by litter to the ambulances in the rear. In camp or cantonment it operates sanitary apparatus and is employed in improving the sanitation of the area. The battalion consists of 13 officers and 306 enlisted men. It is divided into a headquarters and 3 sanitary companies. The headquarters consists of 1 major in command, 1 technical or first sergeant, 1 staff sergeant, 1 sergeant, and 3 privates who act as chauffeur, messenger, and orderly, respectively. Its equipment con sists of a tent and a field desk borrowed from one of the companies. It has no fixed location, but would probably be most frequently placed at a collecting station. No. 4. 581 RAYNOR — MEDICAL CORPS UNITS. THE SANITARY COMPANY. The sanitary company is organized as follows: Captains or lieutenants 4 Sergeants 8 Technical sergeants 1 Corporals 4 Staff sergeants 5 Privates, first class, and privates. 82 The personnel is divided into two sections —a litter-bearer section and a collecting-station section. The number of men assigned to each section can not be definitely fixed, as it varies greatly with the needs of the situation. It frequently happens that no collecting station is needed, or it may happen that the route of evacuation is long and the ambulances are unable to get up close. Under the latter condition the collecting station becomes a very important reinforcement of the aid station and will require many men to handle it. The organization must, therefore, be very elastic. Per sonnel can be assigned at will to duty with either the litter-bearer section or the collecting station, as the situation may require. The table of equipment for the medical regiment has not as yet been completed by the War Department. The table given herein is an extract from a tentative list prepared by the Surgeon Gen eral's Office. It is expected that it will be adopted without material change and may be accepted, for all practical purposes, as standard. In order that each company may act independently when occasion requires, the tables have been prepared with the company and not the battalion as the basic organization. The equipment of the litter bearers is such as can be carried on the person and consists of a litter and a belt. The belt contains pockets for first-aid dress ings. It is not improbable that the belt will be finally adandoned and a pouch slung from shoulder substituted. The collecting sta tion is the rendezvous for the wounded of a brigade, and its equip ment is intermediate between that of an aid station of an infantry battalion and a hospital station of the medical regiment. It is, for the most part, easily packed in boxes and bundles and is transported upon trucks. Each company is allowed four three-quarter ton trucks. The materiel is divided into seven sets, as follows : One set drugs, chemicals, and reagents. One set surgical instruments. One set surgical dressings and appliances. One set hospital furniture and supplies. One set field-equipment supplies. One set food supplies. , One set miscellaneous supplies and equipment. 4539—22 3 582 Vol. XVII RAYNOB —MEDICAL COUPS UNITS. The drugs and chemicals are relatively few in number and consist of such as are commonly used for emergency treatment and the relief of minor ailments. The surgical equipment is designed for emergency surgery and consists of small cases of instruments, needles, simple surgical appa ratus, and splints. The surgical dressings are abundant and complete for their purpose, consisting of large numbers of bandages, rolls of cotton, adhesive plaster, first-aid packets, etc. The hospital furniture and equipment is of the simplest character. It consists of such articles as hot-water bags, basins, instrument boilers, etc. No cots are provided, but litters are available for re cumbent cases. Fifty litters are assigned each company. The field supplies include blankets, carriers (field) for litters, a folding operating table, a venereal prophylactic unit, notebooks, buckets, lanterns, etc. The food supplies consist of cans of milk, soup, coffee, and sugar. The miscellaneous supplies consist of such articles as rope, axes, flash lights, nails, twine, etc. Each station is provided with 2 ward tents. The transportation for each company consists of 4 bicycles, 10 riding horses, 1 kitchen trailer, 1 trailer tank (180 gallons) and 4 trucks (three-fourth ton). The battalion headquarters has, in addition, 1 motor cycle with side car, 1 bicycle, and 3 riding horses. The litter-bearer section works between the ambulance station and the front, for the most part, transporting wounded from aid sta tions to collecting stations and from there to ambulances. It will work in front of the aid stations of the infantry battalions only when the regimental medical detachment is insufficient for this duty. The collecting station should be situated at a convenient place be tween the ambulance station and the aid station of the infantry bat talion. The exact location would, of course, vary with the nature of the terrain and the character of the combat. Sometimes it might not be used at all ; at others, used at the ambulance station as an adjunct, or it might be placed immediately behind the battalion aid stations. In order to give a schematic location for the collecting station, a point may be selected along the line of evacuation about 1,000 yards in front of the ambulance station, which would make it about 2,500 to 3,000 yards from the front. It must be borne in mind, however, that this location is purely schematic and would be varied as local conditions required. In combat, the duty of the sanitary company is to transport wounded by litter under conditions which prevent the use of wheeled transportation. Such work necessarily lies in the front areas.

Normally the wounded will be evacuated by litter to the aid stations by aid station personnel, and from the aid stations to the ambulances by the personnel of the sanitary companies. The organization should fill a long- felt want. There is no part of the evacuation of the wounded more difficult or more important than that which takes place in the front line. No other means of trans portation is possible. When transportation is lacking in the rear, the wounded may be housed in tents and buildings, and their injuries cared for in the interval of waiting ; but on the field the wounded are constantly subjected to additional dangers, and their injuries are be coming progressively more serious and complicated. The prompt re moval of the injured from the field is the first duty of the medical department in combat. The litter bearers from the sanitary company are expected to cover the whole field from front to ambulance station, when necessary, although their prescribed position is the area be tween the aid stations and the ambulance stations. One collecting station is established by each sanitary company, or one for each infantry brigade. They provide temporary shelter for the wounded awaiting transportation by ambulance and are means of affording the wounded more thorough threatment before evacuation than can be furnished at the crowded aid station. As previously stated, the sanitary battalion is employed in time of peace, and in camps and cantonments at all times, in improving the sanitary conditions of the garrison. THE AMBULANCE BATTALION. This unit provides wheeled transportation for the wounded from the battle field to the hospital. It proceeds as near to the front as conditions will permit, and there receives the wounded collected by the sanitary battalion and conveys them directly to the hospital station. The ambulance battalion consists of a headquarters and three ambulance companies. The headquarters is established at an " ambu lance station." Two of the ambulance companies are motorized and one is equipped with animal-drawn vehicles. Twenty ambulances are assigned to each company. The ambulance station is the center of the activities of the ambu lance battalion. From here the ambulances are dispatched to places where they can be loaded with the wounded. The headquarters section consists of a major (in command), a captain, three sergeants, and three privates. There is no prescribed office equipment. Such few articles as are needed are borrowed from the companies. Its transportation consists of a motor car, a motor cycle with side car, and a bicycle. 584 Vol. XVII RAYNOR—MEDICAL CORPS UNITS. Like other units of the medical regiment the location of the am bulance station varies with local conditions. The following general requirements must be satisfied: (1) It must be accessible by road from front to rear; (2) it must be near enough to the hospital to keep in easy touch with it and must be connected to it by a pass able road; (3) it must be as near as possible to the aid stations and collecting stations in order to prevent unnecessarily long carriage by litter and must have access over a good road to these stations; and (4) it must be in a position reasonably well protected against fire. When it is possible to do so the wounded should be evacuated by a different road than that congested with supply wagons of other services. For the purpose of giving it a schematic position, it might be placed in the forward divisional zone about equidistant from the separate ambulance companies and on the road to the hospital station. The reserve ambulance company could also be stationed here. This would (place the ambulance station a little over 2 miles from the front line. From this point ambulances, of course, work forward as far as conditions permit. THE AMBULANCE COMPANY. The two motorized companies and one animal-drawn company of the ambulance battalion are organized and equipped very much alike, except for differences due to the different types of transporta tion provided. There has been a pronounced tendency in recent years to increase the number of motor ambulances at the expense of the animal-drawn, but it has been determined that the animal-drawn vehicle can travel over torn-up roads and plowed fields much better than can the motorized ambulances, and that horses can pull loads where auto mobiles can not go. In view of these facts, we can not as yet dis pense with the animal-drawn ambulance. Excepting that 6 more privates are assigned to the animal-drawn companies, the prescribed personnel for the two kinds of companies is the same. The table of organization is as follows: Captains or first lieutenants 2 Privates, first class, and privates Technical sergeants or first ser- (for animal-drawn) 53 geants 1 Privates, first class, and privates Sergeants 4 (for motorized) 4" Corporals 3 The transportation for the two types of companies is radically different. The motorized ambulance companies are each provided with 20 ambulances, 1 trailer kitchen, 1 trailer tank (300 gallons), No. 4. 585 RAYNOR —MEDICAL, CORPS UNITS* 1 trailer spare parts, 5 trucks (three-fourths ton), 1 motor car, 1 motor cycle with side car, and 1 bicycle. The animal-drawn am bulance company has 20 ambulances, 2 escort wagons, 1 spring wagon, 1 motor cycle with side car, and 1 bicycle. Each ambulance is provided with 1 driver and 1 orderly. This leaves 8 noncommissioned officers and 7 or 13 privates for adminis trative and company duty. The additional 6 privates assigned to the animal-drawn company are charged with the care of the animals. The equipment, other than transportation, supplied the company is of two classes : The first consists of the " ambulance kit," and the second of the " ambulance company sets." The "ambulance kit" comprises appliances and dressings which are carried on each ambulance. They are neither numerous nor bulky. The principal items are 4 litters, 8 woolen blankets, 1 rubber blanket, flash lights, a bottle of aromatic spirits of ammonia, bandages, splints, cotton, adhesive plaster, and first-aid packets. The * sets " furnished the ambulance company consists of supplies which will supplement and replace the articles provided in the "kits." They comprise 40 litters, 80 woolen blankets, 20 rubber blankets, an assortment of splints, a prophylactic unit, and a number of small articles, such as emergency medical packs, notebooks, and pins. The duty of the ambulance battalion is, as its name implies, to con vey wounded from the field in ambulances. Like the sanitary battalion, this organization must be scattered over a wide territory and considerable independence of action al lowed each element. In combat it will be operated more often as three separate companies than as a whole. When attached to a division of two brigades one company will be assigned to each brigade and one will be held in reserve. The action of separate com panies will be coordinated through the battalion headquarters at the ambulance station. This headquarters station takes the place of the old " ambulance control station." The designation " ambulance head" has been discontinued. The activities of ambulances are reg ulated from the ambulance station. On the march, ambulances will be detached from the parent or ganization and assigned to follow the foot troops, one, two, or more per regiment, as conditions require and facilities permit. In widely scattered cantonments it is usually convenient to attach an ambulance or two to different billeting towns. In no case, however, should am bulances pass from the supervision and control of the officer in com mand of the ambulance battalion. This officer should take such steps as may be necessary to insure the speedy assembling of all the ambu lances in his battalion when conditions render it necessary. 586 Vol. XVII BAYNOR —MEDICAL CORPS UNITS. At no time, in peace or war, must the ambulance be used for any other purpose than the transportation of the sick and wounded, and the hospital personnel and equipment. THE HOSPITAL BATTALION. So far, we have considered only such units as are chiefly concerned with evacuation. The hospital battalion affords the wounded the first opportunity to have their injuries dressed, free from the hurry incident to getting them beyond the range of fire. The hospital battalion consists of a headquarters and three hospi tal companies. The entire battalion is normally operated as one unit at the hospital station. Each hospital has a capacity of 150 recumbent cases without crowd ing. An additional 100 can be cared for in an emergency. This brings the maximum capacity of the hospital to 250. About 150 Gold Medal cots and 100 litters are provided for beds. The headquarters consists of 1 major (in command), 1 captain or first lieutenant, 1 technical or first sergeant, 1 staff sergeant, 1 ser geant, and 4 privates first class, and privates. The organization of each company is as follows : Majors 1 Sergeants 7 Captains or first lieutenants 7 Corporals 3 Technical sergeants 1 Privates first class and privates 65 Start sergeants 4 The transportation provided for headquarters consists of one motor car and one bicycle. Each company is provided with 20 trucks (1£ to 2 ton), 1 kitchen trailer. 2 motor cars, and 1 bicycle. As in the sanitary and hospital battalions, the equipment is pro vided on the basis of the company's requirements and not those of the battalion. The equipment per company is approximately as follows : One set drugs, chemicals, and reagents. One set surgical dressings. One set surgical instruments and appliances. '[ One set dental laboratory. ; One set dental, operating. One set hospital furniture and supplies. < One set field equipment and supplies. One chest food supplies. One set miscellaneous supplies and equipment. The set of drugs, chemicals, and reagents is a well-chosen assort ment sufficient for the needs of medical cases and including a liberal supply of antiseptics and disinfectants. The whole set can be packed within a few boxes the size of a steamer trunk. No. i. 587 BAYNOR —MEDICAL CORPS UNITS. The set of surgical dressings consists almost entirely of bandages and dressing packets. It is similar to and about twice as large as the set furnished the collecting station. The set of surgical instruments and appliances contains a liberal supply of the instruments best adapted for general use in major surgery, and an assortment of special instruments for eye, ear, nose and throat, and genito-urinary surgery. This supply of in struments is sufficient for two or three operating teams working at the same time. The hospital furniture and equipment consists of a long list of small articles, such as basins, brushes, crutches, irrigators, litters (100), pillows (150), towels, hospital clothing, etc. The field equipment and supplies consists of 500 woolen blankets, 100 rubber blankets, 6 carriers for litters, a medical and surgery chest, a mess chest, 150 Gold Medal cots, 2 field operating tables, and a number of additional small articles. The dental set contains sufficient supplies for routine dental treat ment and enough laboratory equipment to permit of making splints and other apparatus for treating injuries to the mouth and jaws. The chest of food supplies contains canned soup, canned milk, coffee, and sugar. The miscellaneous supplies and equipment consists of kitchen utensils, axes, spades, lanterns, etc. Especially important items under this heading are 20 ward tents, 4 large and 4 small paulins, and 150 mattresses. From the foregoing it will be seen that the hospital battalion is well equipped to render the necessary immediate treatment required for the sick and wounded of the division. As it is essentially a mobile field unit, it is not expected to provide prolonged treatment which can be better given in the permanent and semi-permanent hospitals in the rear area. THE MEDICAL SUPPLY SECTION. This corresponds to the supply section of the infantry, except that is concerns itself chiefly with the procurement and distribution of medical supplies. Its personnel consists of 2 officers, 3 noncom missioned officers, and 4 privates. THE MEDICAL LABORATORY SECTION. This section consists of 2 officers, 1 staff sergeant, 2 sergeants, and 4 privates. It is provided with complete field laboratory equip ment, packed in 12 chests, each about the size of the regulation trunk locker. The equipment consists of microscopes, an incubator, glass ware, stains, reagents, and other necessary laboratory supplies. The 588 vol. mi RAYNOR —MEDICAL CORPS UNITS. function of the laboratory section is twofold: First, it assists the sanitary inspector by examining food and water supplies and in determining, by laboratory tests, the presence or absence of con tagious diseases in suspected individuals: and. second, it assists the hospital by examining blood, sputum, and other specimens. These are the routine duties of the unit. In addition to this it will render aid in every possible manner by laboratory investigation, in the detection of diseases, and in the treatment of the sick. THE DENTAL SECTION. A dental clinic will be a department of each hospital and will consist of 7 officers and 6 enlisted men. In addition to rendering emergency dental treatment, this section will give advice and assist ance in treating wounds of the mouth and jaws. THE SERVICE COMPANY. This organization corresponds very nearly to the headquarters company of the infantry regiment. It consists of 2 officers, 14 noncommissioned officers, and 26 privates. THE VETERINARY COMPANY. The veterinary service comes under the general supervision of the medical department, both for purpose of administration and supply ; but its evacuation service is necessarily separated from that of the medical department proper and touches it at few points. The veterinary service consists of 5 officers and 14 noncommis sioned officers. It has a special equipment of drugs, surgical in struments and appliances, surgical dressings, and hospital furniture. It is supplied with 16 horses (draft) and 17 horses (riding), 2 trucks (2-ton), 2 wagons, and 1 bicycle. It establishes a collecting station for wounded animals and evacuates chiefly by halter and leading rope. THE HOSPITAL STATION. The location of the hospital unit is designated " hospital station.*' conforming to the usual nomenclature of field medical formations as illustrated by " aid stations," " collecting station," and " ambulance station." The hospital station is usually located near the rear of the division zone. It should be accessible by wagon road from the front and rear. If conditions permit, it should be about opposite the center of the division front. The arrangements of the hospital would vary with the special needs of the station. It would consist of seven departments, as follows : No. 4. 589 BELLI —HYGIENE OF SUBMERSIBLES. 1. Sorting hospital. > 2. Sick and gassed hospital. 3. Surgical hospital. 4. Hospital for transportable wounded. 5. Laboratory section. 6. Supply section. 7. Reserve hospital section. The sorting hospital is the receiving and dispatching unit. It cor responds to the " triage " of the French Army. Here the wounded are classified, recorded, and distributed to appropriate departments. From here they are returned to the front or evacuated to the rear. The headquarters and office are usually located at or near this hos pital. The sick and gassed hospital may or may not be operated as one, depending upon the amount of gas which has been encountered in action. The surgical hospital contains the operating pavilion and beds for dressing serious surgical cases. The hospital for transportable wounded is provided for the slightly wounded. Many of these will not require beds, . as they may be speedily evacuated. The laboratory section, supply section, and reserve hospital section perform the functions implied by their names. The duty of the hos pital battalion is to provide the sick and wounded with immediate definitive treatment, which must be provided before they can be transported to the stationary hospitals in back areas. Units of the corps and army evacuate the patients from the hos pital station. At times the corps will take over the entire hospital and provide the division with a new unit.

HYGIENE OF SUBMERSIBLES.1 PART I. By Capt. C. M. Belli, Medical Corps, Royal Italian Navy. CONSTRUCTION. The introduction of submarines and submersibles has opened up a totally new and very interesting chapter in naval hygiene. On these vessels the conditions of existence are so different that the rules of hygiene for ordinary vessels are inapplicable, and further hygienic research becomes necessary, as, in the World War, these 1 From AunaU di Medlcina Navale e Colonlale, Rome, February, 1922. 590 Vol. XVII BELLI—HYGIENE OF SUBMERSIBLES. new instruments demonstrated an extreme offensive power, and presumably their construction will undergo an extraordinary de velopment. The literature on the hygiene of these vessels is limited to a very few original works exclusively by Italian authors.* The reason for this scarcity of publications lies in the difficulty of un dertaking experimental studies on the subject and in the necessity for maintaining secrecy Vith regard to the internal arrangements of the vessel.3 Until the beginning of the war the architecture of the submarine was shrouded in an atmosphere of mystery. After the seizure of the Austro-German submarines by the Entente and, reciprocally that of the allied submarines by the enemy, the motive for this reserve, at least concerning past methods of construction, ceased, and at this time it is possible, without violating any military secrets, to base our naval hygienic considerations upon a knowledge of the internal ar rangements and instruments on board these vessels. To-day the true submarine has been abandoned, and there is being constructed only the submersible torpedo boat, known as the sub mersible; that is, a boat which ordinarily travels on the surface of the water, and which, in order to attack the enemy or to retreat, can submerge to such a depth as to render it invisible and invulnerable. From the nautical point of view the two types of boats are distinct, because the submarine has a reserve buoyancy less than 10 per cent of the displacement, while that of the submersible is greater. In the latter, with a considerably increased bulk, the conditions of life are more favorable; a large portion is above water, and the entire ma neuvering station remains at a convenient height above sea level, so that the crew, when the submersible is navigating at the surface, can take the air on deck. The large submersibles have a displacement of from 1,500 to 2,000 tons, the more recent ones reaching even 5,000 tons; their length is 70 meters or more, and they have two screws. They attain a speed 1 Belli : Hygienische Betrachtungen fiber unterseelsche Schlffe, "Arch. f. Scblffi u. Trop. Hyg.." 1905.

Nav.," 1917. 3 To give an idea of the jealous care with which construction secrets are guarded. I will relate an incident within my experience. In 1905, having published an article on the hygiene of submersibles based on a German review, I was accused of divulging military secrets. Naturally the inquiry brought to light that the State defense had suffered no danger through the incriminating article. For the successive publications I obtained the licet of the general staff. Public authorization has been given for issuing the data of the present work. No. 4. 591 BELLI—HYGIENE OF SUBMERSIBLES. of 25 miles on the surface and 15 miles immersed, and can submerge to a depth of from 30 to 40 meters. The large tonnage permits the quartering of a crew of 40 or more men under sufficiently comfortable conditions, the carrying of enough fuel for a radius of action of more than 6,000 kilometers, and every thing else necessary for navigation, so as to be able to remain away from the base 30 or 40 days. These vessels are divided into two classes: Those with single, spindle-shaped hull, Holland type (English), and those which are double, with an inner, pressure-proof hull, the exterior being in the form of an ordinary ship— the Laurenti type (Italian), Krupp (Ger man), Laubeuf (French), Lake (American). The difference between the types consists essentially in the method of immersion, the interior arrangement being approximately identical. In the type with double hull, the inner one represents the true hull. The intervening space is subdivided into water-tight compartments which are either empty or else form tanks for water ballast or liquid fuel. The walls separating the compartments are water-tight and permit the boat to maintain a certain degree of floatability in case of leaks involving the two hulls and flooding one compartment. The doors between compartments are likewise water-tight. The submersible can navigate at various depths, such as : (a) On the surface of the water. (b) In the awash state, more or less emerged (with only the peri scope showing or with the whole tower out of water) . (c) Completely submerged. Submerging is accomplished by automatically filling the proper compartments with sea water, which enters by an aperture in the outer hull furnished with valves. A return to the surface is accom plished by expelling the sea water from the compartments, using turbine exhaust pumps run by electric motors. Under exceptional circumstances compressed air is introduced into the compartments, but this is regarded as a means in reserve. The transition from the one method of navigation to the other is accomplished in two or three minutes. Submersion can last more than 24 hours. With complete submersion the conditions of visibility are anal ogous to those which prevail on a steamer enveloped in a thick fog, vision through the mass of water not being possible beyond a few meters. With partial immersion, visual perception is accomplished by means of the periscope, a sort of telescope formed with a cylin drical tube which may be raised to the surface of the water (nor mally it is held at about 80 centimeters) or lowered, and which by means of combinations of lenses and prisms furnishes a means for discerning objects almost as with the naked eye. In the reflector of the periscope is seen only an eighth part of the horizon, which, how 592 Vol. XVII BELLI —HYGIENE OF SUBMERSIBLES. ever, may be entirely scrutinized by turning the instrument so as to- change the field of vision. Underwater navigation is silent because the electric motors while running make no noise. The silence is broken only by the sound of the screws of near-by vessels, which is detected by means of acoustic receivers adjusted for purposes of offense and defense. INTERNAL STRUCTURE. In submersibles of a single hull, three planes are considered: Deck, main corridor, and hold. In submersibles with a double hull there is a fourth plane, constituting the double bottom. Deck plane. —The deck has a form like that of a torpedo boat, but the central portion is narrower and the ship's sides slope to the sea with an incline much more accentuated. In the central part rises the conning tower, with its two peri scopes. Hatches, the ventilation tubes, and the passages for the guns and torpedoes open forward and aft of the conning tower; above appear the radio antennae and the periscope tubes. The conning tower has a superstructure around the walls of which are arranged port holes for use when the boat is emerged; hatches open from the roof giving access to a companionway lead ing to the rooms below. It is superimposed upon the control room and contains the governing apparatus. Only when in port does the hull stay open; exceptionally it is open when navigating at the surface, with the sea perfectly calm. Under these conditions the personnel may come upon deck, which with ordinary navigation remains clear. Corridor plane. —This is constructed so that the inside -walls of the hull form those of the corridor, the flooring beneath being of metal strips. All the surrounding chambers are intercommunicating by means of apertures fore and aft. On the Laurenti type of sub mersibles there is a second passage across the intervening space between the two hulls, which makes it possible to pass from bow to stern without going through the accumulator rooms. Such a pas sage is arranged for the safety of the personnel in case of accident. When the tubing is damaged, or through some other cause the sea water penetrates the accumulator boxes and comes in contact with sulphuric-acid gas, there is a strong development of chlorine which renders the air unbreathable. Under these circumstances this pas sage offers a safe exit for the personnel. The number of compartments into which the hull is divided bears a direct relation to the dimensions of the boat. With the exception of the two extremities, which remain empty, these compartments are used as living quarters, control room, torpedo launching rooms, motor (heat and electric) rooms, and for electric accumulators. The quar No. 4. 593 BELLI —HYGIENE OF SUBMERSIBLES. ters for the crew and officers are located in the central compart ments. On account of the small amount of space and its arrangement, living conditions were very unsatisfactory in the first submersibles. The crew, in carrying out maneuvers and while resting, occupied very uncomfortable positions. With increased size of the boe.ts. their underwater characteristics changed and more nearly approached the conditions which obtain on ordinary vessels. The crew now enjoy relative comfort and can carry on their regular occupations without any difficulty. On the large submersibles there is a spa cious dormitory for the crew; but also on the smaller ones every man has a hammock or a small camp bed. The officers are lodged in one or more small rooms with a bunk for each officer and they have a small wardroom. In the same central part of the boat there is a stove, cook's galley, steward's room, and two toilets. The stove is electric; a coal stove can not be used, because fire consumes oxygen which is very necessary for respiration. One of the most difficult problems to solve has been the installa tion of toilets. At first, provision was made for the removal of ex crement through deodorizing boxes. Recently a convenient system of toilet cabinets has been devised, having an arrangement of double valves and a pump, such as are used for torpedo boats, but with the difference that the material is ejected from the ship by a stream of compressed air. The capacity of the compartments, both absolute and relative to the number of persons, varies essentially according to the size of the ship. Nevertheless, bearing in mind the serious causes for viti ation of the atmosphere, in order to give to each individual the greatest possible quantity of surrounding air, the number of men is restricted, and as a consequence each person has a larger amount of work to perform than on ordinary vessels. From the data published by Marantonio upon the German sub mersible seized during the war by the Italian Navy, and rebaptized Balilla, I have calculated the amount of surrounding air per person and per space. Amount of Inclosed space. Cubic capacity (meters). Number of atmosphere per person (cubic persons. meters). 92 14 6.5 31 2 15.5 79 3 26.0 101 5 20.0 43 5 8.5 131 3 43.0 81 4 20.0 Total 558 36 594 Vol. XVII BEIXI—HYGIENE OF SUBMERSIBLES. On this submersible, with a total air capacity of 558 cubic meters and a crew of 36 persons, the average surrounding air per individual is 15.5 cubic meters, with a great difference between one place and another, varying from a minimum of 6.5 to a maximum of 43.0 cubic meters. In an absolute sense the proportion can not be considered small, being greater than that for the majority of ordinary ships; in a relative sense, when submerged, it is sufficient to insure respiration to those on board for but a few hours. The average is attained when all the spaces freely communicate ; but the amount varies with the opening and shutting of the various doors communicating with the different compartments. Torpedo-launching rooms. —These contain the torpedo-launching tubes and the torpedoes kept in reserve; if the boat is of average tonnage, the spare space is utilized as a dormitory for the crew. Control room. —This is located beneath the conning tower ; here are assembled the two periscope tubes, the telephones, the speaking tubes, and the radio apparatus. Engine rooms. —The propulsive motors are of two varieties : Heat engines for navigation at the surface, and electric motors for under water navigation. The heat engines are generally of the type designed for oil com bustion (gasoline and similar products) ; however, the more recent French and English types use the steam-turbine variety. The heat engines propel the vessel when at the surface or when partially submerged, as long as it is possible to keep open the tubes surrounding the periscopes through which passes the air needed for combustion. They are arranged in pairs, two on each side, respec tively. The products of combustion are expelled through two large tubes, one on each side, corresponding to the smokestacks of ordinary vessels. The tubes pass through the double bottom on each side and expel their contents above the water line. From the hygienic point of view in this class of ships, the com bustion motors present two advantages: They heat the surrounding atmosphere less, sufficient coolness being maintained by means of water circulation, and, by introducing the air necessary for running the motor, ventilation is aided. With turbine motors cooling can not be effected by means of water circulation, and in this type of motor, notwithstanding the covering of the hottest pieces with insulating material, there is ex cessive heat radiation into the surrounding atmosphere. Such an inconvenience may be remedied, up to a certain point, hy separating the engine room from the other compartments by walls with a water circulation and by systematic forced ventilation. The primary function of combustion motors is to furnish mechani cal energy for navigation at the surface; but these motors can. No. 4. 595 BELLI—HYGIENE OF SUBMERSIBLES. through the working of the dynamo, charge the storage batteries which supply the energy to the electric motors for partial or com plete underwater navigation. In the vicinity of the heat motors are the pumps for exhausting water and the air compressors; all this apparatus causes excessive crowding of the compartment, leaving only a very narrow space in the center. In the same compartment in a small boat, in a special one in the larger types, are installed the electric motors with continuous cur rent, which, while the vessel is running submerged or partially submerged, take the place of the combustion motors. The motors, by virtue of their reversibility, are at the same time the regenerators of the electric current (dynamo), and when the boat emerges serve to charge the batteries, which also are charged at the shops on shore or by mother ships. Battery compartment. —The batteries which furnish electric en ergy to the motors for navigating submerged are located in one or two compartments on the plane of the central passage ; in some boats on the plane of the hull. These batteries are of the sulphuric-acid or liquid type. The ordinary batteries preferred in the European submarines are composed of impermeable boxes of ebonite, closed by covers provided with holes for the passage of the poles. They are fastened perfectly water and air tight in order to prevent the creeping of the electrolyte and the escape of gases generated by the development of the electric fluid. Inside the boxes the lead plates are arranged in series, separated one from the other by strips of rubber and immersed in dilute sulphuric acid. The Edison alkaline batteries employed in American submersibles are made of steel and nickle and contain a solution of potassium. As compared with the ordinary type, they present the following notable hygienic advantages: By doing away with sulphuric acid, they remove the possibility of the generation of gases (sulphuric anhydride and chlorine) which render the atmosphere unfit to breathe, thus affording a great improvement in the matter of res piration and avoiding the possibility of serious accidents; they oc cupy an appreciably smaller space and require less attention; on the other hand, from the technical point of view, they are inferior to the ordinary sulphuric-acid types. Plane of the hold. —This portion of the boat is set apart for the storing of ammunition, fuel, compressed air, water, and the other requirements for navigation. Liquid fuel is stowed in perfectly closed tanks, from which it is conveyed to the motors by pumps. The air under a compression of 150 to 180 atmospheres is con served in steel tanks arranged as far as possible beneath the floor 596 Vol. XVII BELLI —HYGIENE OF SUBMEKSIBLES. ing of the engine room. The amount provided is in proportion to the dimensions of the boat, attaining quantities of 10 and more cubic meters to every 2 tons of weight. The replacement of the air consumed or lost through the tubing is effected by means of force pumps which operate when the vessel is completely emerged. A system of piping leads from the tanks to a tap provided with valves in each compartment. In one of the compartments is located the fresh-water tank of a form and construction similar to that in ordinary ships. In the deepest part of the inner hull is the bilge, which is almost inaccessible when all the apparatus and appliances are in place. Double bottom,. —The double bottom for the water ballast ex tends the whole length of the hull in the Krupp and Laubeuf types, is limited to the central part of the boat in the Holland and Lake types ; likewise to the center but shorter in the Laurenti. In certain types some of the compartments with a double bottom are filled with a material which expands on contact with sea water thus clos ing any possible leaks. The double bottom being ordinarily closed, without communica tion with the surrounding portions of the ship, has no importance as regards hygiene, except when entered for cleaning and repair work. INTERNAL ATMOSPHERE. Submersibles when navigating on the surface of the water, both from the nautical as well as the hygienic point of view, do not present notable differences over ordinary torpedo boats, and within certain limits the same principles imposed by naval hygiene on the latter can also be applied to them. The submersible is characterized by the ability to navigate beneath the surface, in which condition it constitutes an hermetically closed space, circumscribed by imper meable walls, entirely surrounded by a thick stratum of water, and absolutely separated from the atmosphere. This being the case, the following questions arise : First. What are the causes of the changes which the air undergoes inside the vessel? Second. In what proportion do they occur and which of them pre dominates? Third. What index may be adopted as the limiting factor of these changes? 1. Causes of the deterioration of the air.—In ordinary ships the causes which produce the vitiation of the air are chiefly the function ing of the vital organs of man and the various and complex activities in which he engages. In submersibles the causes of the vitiation of the air are similarly complex, but have different effects owing to the fact of the space being hermetically inclosed. No. 4. 597 BELLI —HYGIENE OF SUBMERSIBLES. Man renders the air impure through his biological functions. Respiration and cutaneous perspiration produce chemical and physi cal changes in the air. An adult man, working moderately, subtracts every hour from the surrounding air by his respiration 42 grams of oxygen and gives off 47 grams of carbon dioxide, as well as a small and variable quantity of ammonia, sulphureted hydrogen, and heavy volatile acid. At the same time, man emits every hour with his pulmonary respiration and cutaneous perspiration 50 to 60 grams of water. Furthermore, man vitiates the air by the. radiation of heat. Engaged in moderate work, man emits every hour by radiation about 100 calories. The thermic capacity of the air is 0.35 calory per cubic meter, whence through this single source of heat, if no absorp tion of heat by the water surrounding the boat takes place, the tem perature of the air inside the latter will be noticeably increased. Man also vitiates the air with tobacco smoke. Lastly man causes a final vitiation of the air by carrying on board in his clothing and various objects the finely pulverized dust of the outside atmosphere. Another important cause of the chemical and physical vitiation of the atmosphere lies in the heat and electric motors. The heat motors produce chemical changes with their products of combustion and with the gases thrown off into the atmosphere by the fuel carried on board. The fuel employed for the heat motors is composed of the residues of the distillation of petroleum, the principal products of combustion of which are carbonic anhydrid and water vapor, while the secondary products are oxide of azote (which is subsequently converted into hypoazotite), nitrous or nitric acid, methane, acetylene, and various other substances. The gasoline tanks are closed hermetically, hence theoretically no loss from them should take place. In actual prac tice, however, small quantities of gas escape from joints of the tubes and valves and become mixed with the inside air. When the sub mersible is in confmunication with the external air, the gasoline vapors escaping from the tanks and the products of combustion are quickly expelled outboard by the exhaust ventilators, so that the air is completely changed at frequent intervals; but if submersion fol lows immediately upon the stopping of the engines, there is no time for completely renewing the air, which therefore remains vitiated. Electric motors vitiate the air by the functioning of the accumu- . lators. The reaction of sulphuric acid on the metal develops hydro gen, which in part reduces the sulphuric acid, with the production of sulphureted hydrogen and sulphurous anhydrid, and is in part set free. The storage batteries are inclosed within impermeable boxes from which the gases are carried directly outboard by means of 4539—22—4 598 BELLI —HYGIENE OF SUBMERSIBLES. Vol. XVII proper ventilators ; consequently, except in case of damage or break age, these gases can not be given off into the surrounding air except in a minimum quantity. Finally, a chemical vitiation of the air is produced by the lubri cation of the machinery, which is accomplished with heavy mineral oils introduced into the parts in motion to diminish wear and for the purpose of saving motive force which would otherwise be lost. These oils distill at a temperature above 200° C. They constantly contain, however, a greater or less quantity of light oils having a lower boiling temperature, which in contact with the superheated parts of the engine become gaseous and mix with the surround ing air. The physical change in the air produced by the functioning of the heat and electric motors consists in the elevation of the temperature. The consumption of gasoline varies with the speed; its calorific power is very high, namely, 1,136 calories, so that at cruising speed several hundred thousand calories are developed per hour. The greater part of the heat energy is transformed into mechanical work, but a portion is given off into the surrounding space. The same thing happens with the electric motors. The mechanical energy furnished by the electric motors does not correspond to the energy consumed. A portion of the latter, about 0.17 of 1 per cent, is trans lated into the development of heat, which increases the temperature of the inclosed spaces in question. In a submersible of large dis placement there are developed jn this way more than 10,000 calories per hour. Ordinarily the storage batteries are charged at the elec trical stations on shore and are placed on board already in a charged state, so that the development of heat in discharging is a minimum, and the surrounding temperature is therefore not increased in this way. This is not the case when the storage batteries are charged on board, because in performing this operation the temperature of the jars is increased and heat is given off into thf surrounding air. The ventilators carrying off hot air lower the temperature unless submersion takes place immediately after stopping the motor. Secondary causes of physical and clinical changes in the air reside in artificial illumination, the varnish of surfaces, the escape of compressed air, and ventilation. Illumination is accomplished by means of incandescent electric lamps, which entail a slight increase in the temperature of the air by the radiation of heat. In fact, a 16-candlepower lamp radiates 40 calories per hour, so that supposing there were 50 lamps giving out radiation there would be about 2,000 calories per hour. The sheet metal is coated with lead and covered with enamel varnish which is likely to become oxidized, thus drawing oxygen from the air. No. 4. 599 BELU —HYGIENE OF SUBMERSIBL.ES. During the maneuver of emersion, while ballast water is being exhausted by compressed air, an amount of air escapes which, though slight, is still sufficient to cause an increase of the pressure of the inner atmosphere. Immersion is regulated by means of a compensating tank located beneath the floor of the control room. Two air exits are provided from the tank, and during immersion the air exhausted from the intervening space is replaced by an equal volume of water. If the tank is allowed to remain empty for a period of time the air is vitiated by the gases arising from putrefaction of the sea water remaining on the floor, and the introduction of this air into the interior of the boat causes chemical changes in the atmosphere and increases the barometric pressure. Finally, ventilation by means of the outside air introduces into the submersible the fine dust held in suspension in the atmosphere. The process of deterioration of the air is not continuous ; the chem ical changes depending upon the biological functions of man are constant; on the other hand, those proceeding from the running of the engines are produced in proportion to the amount of the latter, considered in terms of the duration of functioning and the tempera ture attained by the parts of the machinery. Therefore, in every operation of the submersible three periods must be distinguished: In the first period navigation takes place at the surface, and there fore the changes in the air are caused by the heat of the motors ; in the second period the submersible navigates beneath the surface of the water where the changes in the air are caused by the heat motors and batteries ; finally, in the third period, in resuming ordinary navi gation, we return to the first condition. Therefore, not only are the changes different in the three periods, but in the second the changes of the first persist in part, to which are added those proper to the second period ; the same is true of the third period with respect to the two preceding ones. Kind of changes in the air and their value. —The changes caused by man are based on physiological data and can be calculated with sufficient approximation. On the contrary, the physical and chem ical modifications derived from motors and other above-mentioned causes are variable inside of wide limits and may be ascertained only through direct investigation. Complete researches were effected by Belli in a series of collaborations with Trocello, and again with Olivi, in which the results obtained were very nearly coordinate. Organoleptic properties.—The air in a submersible after several hours of immersion develops a special odor, differing from the musty odor of an inclosed compartment on land in that it irritates the mucous membrane because of the presence of sulphureted anhydrid 600 Vol. XVII BELLI —HYGIENE OF SUBMERSIBLES. developed by the batteries and hydrocarbonates escaping from the motors by explosion. Physical characteristics.—The physical changes of the air have on the whole a limited importance. Temperature.—The temperature upon first immerging is raised from 2° to 3° C. above the external temperature, but tends afterwards to a thermic equilibrium with the various surroundings and with the water round about. The reason for this fact is found in the physical conditions of the submersible with respect to its external surround ings. The hull is of steel, one of the best of heat conductors, and is surrounded on all sides (during immersion) by a liquid medium that possesses a great capacity for heat; therefore from the walls there will be a strong caloric dispersion into the surrounding water. The ini tial increase is due to the heat from the gasoline motors; but with the hull closed and immersed, notwithstanding the great radiation of heat from the several sources (machinery and men), the dispersion of heat is such that the temperature of the air is principally domi nated by that of the sea water, with which the internal atmosphere tends to put itself in thermic equilibrium. Immersions are made to a depth of from 20 to 40 meters, where the temperature of the sea water is influenced by the seasons. In Italian seas the temperature of the water near by and round about is slightly higher than the air above; this explains why the temperature of the submersible is higher than that of the external air measured before immersion. The temperature, then, is maintained within limits tolerable to the human organism. In temperate seas, during immersion in the cold season, the air in a submersible is rather cold ; but keeping warm is not difficult with suitable clothing and through artificial electric heating. In the summer season the temperature does not often go higher than 30° C. and, being accompanied by a high degree of at mospheric humidity, causes great discomfort, as in places oppressed with a hot-humid atmosphere. The air in proximity to combustion motors is hotter than in other portions of the vessel and ventilation tends to spread this heated air, at least when immersion follows imme diately upon the stopping of the motor. Humidity.— The relative humidity increases up to 90 per cent and over, reaching at some points saturation, as is demonstrated by the tiny drops of moisture condensed on the walls. The increase is not so great as it should be when based on the water vapor calculated to be normally thrown off by man. The reason for this, however, has not been determined. Every opening which would permit the entrance of outside air is closed, hence the water vapor, a product of the various degrees of humidity on board, accumulates in the internal atmosphere. No. 4. 601 BELLI—HYGIENE OF SUBMERSIBLES. The interior of the submersible being restricted, the air can absorb only a limited quantity of water vapor. For this reason, in the cold season, the temperature of the air being low, saturation is accompanied by a relatively low degree of water vapor. The increase, however, when the immersions are of brief duration and in the winter has but slight effect upon the organism. When the immersions are made in the summer season, with the temperature higher than 30° C, the excessive humidity of the air causes a feel ing of annoyance when the stay below water is protracted beyond a certain period. Barometric pressure. —The atmospheric pressure increases with respect to its environment from 10 to 30 millimeters, but the varia tions are less regular and constant than those of temperature. The increase of pressure may be attributed in part to the escape of hydrogen and other gases from the electric storage batteries, but it is principally derived from the escape of compressed air from the air tubes and valves. At the moment of emersion, before opening the small doors, the air valves are opened, which gradually places in equilibrium the internal and external pressure, thus avoiding sudden pressure changes. Chemical composition of the air.—The chemical changes are much more important than the physical ones. The chemical composition of the atmospheric air undergoes quantitative modifications in its normal components, and qualitative ones through the addition of gaseous impurities. The variation of these components is represented by the diminu tion of the oxygen and an increase of the carbon dioxide. Oxygen. —The percentage of oxygen in the air undergoes a dimi nution greater than the consumption of oxygen by the processes of organic combustion through the men of the crew, because a portion of the gas serves for other oxidations, especially for those of the hydrocarbons of the motors. The diminution is proportional with the duration of immersion, and a minimum percentage of 18 was noted in an experiment of Belli and Olivi after 6 hours of immersion. With the successive renewals of air (always in the position of immer sion) the percentage increased to about 19 and fluctuated around this figure for the rest of the experiment; that is to say, for the next 18 hours. It may then be maintained that with normal immersions the quantity of oxygen remains sufficient for respiration, it being ascer tained in physiology that asphyxiation occurs only when the pro portion of oxygen in the air falls below 3.5 per 100, which can only happen in case of mischance. Carbon dioxide.—The proportion of carbon dioxide varies ac cording to whether the men work or remain in repose. With the diminution of oxygen, the increase of carbon dioxide is greater than 602 Vol. XVII BELLI —HYGIENE OF SUBMERSIBLES. that dispersed in the air through the process of respiration, because there exist other causes than that of animal respiration. In the ex periments of Belli and his collaborators the increase was gradual and reached the proportion of 31 per 1,000 after the first 6 hours of immersion. The experiment was protracted for 24 hours; but after 6 hours the physical-chemical state of the air became almost in tolerable (because it was the month of July) and the air was renewed about every 5 hours. After every renewal the proportion was low ered between 13 and 17 per cent, rising promptly to its first figure and reaching at the end of the experiment, after 24 hours, 37.2 per 1,000. The increase was without doubt significant; however, no alarm ing toxic phenomena were observed. This knowledge assumes a special importance even for general hygiene, inasmuch as it demon strates that with a proportion of carbon dioxide of 37 per 1,000 man can live and attend to a certain amount of work. Gaseous impurities. —The gaseous impurities, represented by gases extraneous to atmospheric air, are as follows : Indifferent: Hydrogen. % Unbreathable : Sulphurous anhydrid. Poisonous : Hydrogen sulphid, chlorine, hydrocarbonates, car bonic oxide, ammonia, nitrous and nitric anhydrid, arseni- ureted hydrogen, organic gaseous substances of an inde terminate nature. Hydrogen. —The presence of hydrogen may be presumed because of the functioning of the electric storage batteries, since hydrogen is derived from the same chemical reaction from which originates sulphurous anhydrid and sulphureted hydrogen, as demonstrated by the researches of Belli and his collaborators. Hydrogen is in different to the human organism and produces no harm through inhalation, but it is dangerous because in certain proportions (from 9 to 66 pet- cent) it forms with the air an explosive mixture. Sulphurous anhydrid. —Sulphurous anhydrid produces a very powerful effect on the organism, especially when combined with air to be breathed. In air which contains 0.05 of 1 per cent of it, animals can not breathe without suffering, and with a dose of 0.24 of 1 per cent a rabbit is killed in about 4 hours. In the researches cited above, a maximum of 0.314 gram per cubic meter of air was demonstrated after 20 hours, a small quantity, but sufficient to ex plain, in combination with the other poisonous gases, that slight feeling of suffocation which gives warning during a prolonged im mersion. Sulphureted hydrogen.—Sulphureted hydrogen is also a most poisonous gas, killing a dog in an atmosphere containing 0.125 of No. 4. 603 BELLI —HYGIENE OF SUBMERSIBLES. 1 per cent of it. In submersibles it has been found in the proportion of 0.00049 gram per cubic meter of air, a quantity which can not affect the health. Chlorine. —Ordinarily chlorine is completely absent; in case of accident it is produced by the penetration of sea water inside the electric storage batteries. The escape of chlorine is very dangerous, as it is highly noxious in the proportion of 1 to 10,000. Hydrocarbonates. —Hydrocarbonates collect in quantities of 0.1449 gram per cubic meter of air. This quantity is already found at the beginning of immersion, and neither increases or decreases when immersion is prolonged— a sign that it is produced mainly through the gasification of gasoline in motors as well as from the lubricat ing oils. The chemical composition of the derivatives of petroleum is varied and their toxic power is in correspondence therewith. The poison ous effect depends upon the dose and upon the duration of inhalation. The quantity found was so small as to produce but slight effect even if it were of the most poisonous quality. Carbon monoxide, ammonia, nitrous and nitric anhydrid. —These have been absent in all researches. Arseniureted hydrogen.—Arseniureted hydrogen may be present because of abnormal reactions from the batteries. It is a toxic gas in the proportion of 1 to 100,000. Giordano has observed two almost simultaneous instances of poisoning from arseniureted hydrogen on board two submersibles. They were equipped with storage batteries, which were not only unprovided with air-tight tin covers, but also the ventilating hole on the inside of the box was in direct communication with the sur rounding air. The lead plates were enveloped by asbestos sacks, in order to prevent, under the action of the movement of the vessel, the crystals of lead oxide, which particularly form in positive plates, from falling to the bottom of the box. A chemical examination demonstrated the presence of arsenic in the asbestos and traces of arseniureted hydrogen in the air during the functioning of the storage batteries. The presence of arsenic in asbestos which is of recent manufacture and used for the first time might cause a throw ing off of arseniureted hydrogen as well as hydrogen alone. With the successive charges and discharges of the storage batteries the greater part of the arsenic is eliminated and, as has been proved on experimenting with animals, the small portion which still escapes does no harm. Similar cases of acute poisoning from arseniureted hydrogen have been observed on a French submersible after two consecutive im mersions, each of 18 hours. An examination of the air of the sub 604 Vol. XVII BELLI —HYGIENE OF SUBMERSIBLES. mersible revealed the presence of arseniureted hydrogen developed from the batteries of the accumulators. Other cases have been noted upon English submersibles, caused by the use of lead plates or of sulphuric acid containing arsenic. The development of toxic gases takes place particularly during the charging of batteries. To avoid the development of arseniureted hydrogen it is necessary to employ lead free from arsenic, and sulphuric acid which contains not more than 0.0008 part of it by weight. In all cases it is necessary to thoroughly ventilate the battery an hour before the charging of the accumulators and while in use. Atmospheric dust. —This is made up of those mineral, vegetable, and animal particles which in small quantities impregnate the atmos phere, causing no special effect. It is of minimum quantity. Organic substances of indeterminate nature having a toxic effect. — An individual who remains in a hermetically inclosed space admitting no outside atmosphere suffers disturbances which grow from a simple feeling of discomfort to the gravest symptoms of asphyxiation. The cause of symptoms produced in confined air is not definitely known, and various hypotheses have arisen in explanation. Sanarelli, Biffi, Hermans, and several others are of the opinion that the poisons found may be due to processes of putrefaction thrown off by the skin, from intestinal fermentation, from disease conditions (ozena, fetid breath, dental caries, etc.). Other authorities, while admitting the formation in the stagnant air of malodorous com pounds, deny that they may have any toxic effect and that their quantity is such as to cause symptoms. Wolpert . holds that the phenomena are due to the diminution of the quantity of carbon dioxide eliminated from the crowded compartments. . Weichardt attributes the disturbances found in the inclosed spaces to the waste products analogous to the colorless, odorless toxic gases formed under fatigue. Fliigge excludes the presence of toxic products and at tributes the cause of the symptoms to physical factors in the sur roundings, such as increase of heat, humidity, and immobility of the air. . , On Italian submersibles no serious disturbances have been observed. The men confined for long hours inside the boat experienced only cephalgia and mental torpidity, occasionally assuming the form of complete lethargy. In the confined atmosphere of a completely submerged submersible a considerable quantity of carbon dioxid is accumulated; and sulphurous anhydrid, sulphureted hydrogen, and hydrocarbonates are present. There are likewise present in a con siderable degree the physical factors mentioned by Fliigge (immo bility of the air and its high thermic and hygrometric quality). This to me seems sufficient to explain the symptoms. No. 4. 605 BELLI—HYGIENE OF SUBMERSIBLES. Predominance of the various air changes in different localities.— The physical-chemical state of the air differs in various locations, according to the number of men and the kind of machinery and ap paratus on board. In the torpedo and control rooms the changes of the air are principally due to the presence of persons. In the combustion and electric-motor rooms they are to be attributed to the combustible and lubricating oils for the engines, and in the accumu lator space to the chemical reactions of the accumulators. However, the differences between the communicating rooms tend to disappear, because inside a closed boat the air becomes rapidly mixed through the law of the diffusion of gases and by means of differences in temperature. The difference is maintained, in particular localities, because of the different densities of gases, hence carbon dioxid, which is heavier than air, collects in the lowest parts of the rooms. 3. Index of the limiting factor of the changes. —The changes of the air during immersions of brief duration have no injurious results and in no way threaten life; however, when the time is prolonged it may reach such a point as to bring serious danger. A criterion which might warn the crew of the approach of danger would be, however, of the highest utility. The quantitative modifications of oxygen and of carbon dioxid are not constant, and still less constant are the gaseous impurities thrown off into the atmosphere of submersibles. We can not therefore fix basically the physiological data nor the experimental results of the maximum duration of immersion. In dwellings the sense of smell gives warning that the impurities of the air have reached the limit of tolerance of the human organ ism ; but this sense, although very keen, is dulled when exposure is protracted for any length of time and especially in' an atmosphere containing gases which have different effects, so men who are con fined in submersibles do not receive this physical warning of immi nent peril. In default of olfactory warning, small, warm-blooded animals may be employed, such as rats, guinea pigs, and pigeons. Upon the first submersibles it was customary to carry small rats in cages, , as their death gave warning of the beginning of danger for man, who would then have a chance to escape. As a matter of fact, rats are very sensitive to toxic gases (especially carbonic oxide) and die in 10 minutes in an atmosphere where a man may live an hour. In the experiments of the authors quoted above the rats did not give any sign of suffering, so that this physiological check proved the result of the chemical research as to the absence of carbonic oxide from the air. The indication given by the death of the rats may be late in manifestation, hence this method often fails in its aims. On the other hand, on recent boats, the danger of carbonic oxide being eliminated, the need of animal proof is obviated. 606 Vol. XVII BELLI—HYGIENE OF SUBMERSIBLES. The proof of a lighted candle going put in this atmosphere is valueless, because in an atmosphere harmful to man there is still enough oxygen to feed the flame. On shore our only index of impure air is the presence of carbon dioxide in dwellings, and the maximum limit is fixed as 1 part to 1,000. May not the same index be adopted for submersibles ? If we consider only the carbon dioxide thrown off by the respira tion of man, in a little over a half an hour in a submersible of average size the limit is attained. The net air capacity of a submersible for maintaining life would permit of immersion of less than an hour. In actual practice, however, it happens otherwise. Kespiration in side a submersible during immersion is not as agreeable as when in a balmy wood, but experience demonstrates that it is possible to live and work there for several hours without appreciable suffering. The reason for this apparent contradiction is not hard to trace. The maximum quantity of 1 to 1,000 of carbonic dioxide admitted by the hygienists does not represent the limit of tolerance for this gas, but it has been assumed as the easiest appreciable exponent for the com plex changes which the air undergoes in the confined surroundings of dwellings on shore. The vitiated air within a confined space may become harmful in two ways: By slow and continuous action in the form of chronic poisoning, or by the rapid action of acute poisoning. In the first in stance there will be a lowering of hematosis, of nutrition in general, and of all vital powers of the organism. In the second case, acute asphyxiation is brought on, as in the tragedy of the Black Hole of Calcutta, in which out of 146 prisoners after 8 hours' confinement, there came out alive only 22; and that of the boat Londonderry, where, out of a crew of 200, 72 died. The measure of carbon dioxide was proposed by Pettenkofer as an expression of the degree of purity of the air in dwellings for a pro longed and continuous sojourn; on the contrary, the limit of toler ance of carbon dioxide for a brief sojourn is very much higher as demonstrated in the personal example of Pettenkofer, who stayed several hours in an atmosphehre of 10 to 1,000 of carbon dioxide with out discomfort, and that classic incident of the chemistry hall of the Sorbonne with a proportion of carbon dioxide of 10 to 1,000, and, to remain in the field of naval hygiene, that of Belli and Trocello in the dormitories of the torpedo chasers, 11 to 1,000, without apparent dis turbance to the crew. In dwellings on land the content of carbon dioxide has been se lected as an index of the corruption of the air, because of the suppo sition that the substances constituting the true changes, and especially the supposed volatile toxins emitted with respiration, proceed co No. 4. 607 BELLI —HYGIENE OF SUBMERSIBLES. equally with the quantity of carbon dioxide ; but the parallelism be tween the carbon dioxide and the other gaseous impurities does not exist, and the contrary is, moreover, the case. In submersibles the factors which change the composition of the air, whether with regard to the modifications which occur or from the point of view of the loss of purity, are not the same as with dwellings on land, for the reason that the proportion of carbon dioxid as an index of the contamination of the air can not be fixed on a scientific basis. At all events, wishing to accept this criterion, we must raise the limiting factor at least to 15 to 1,000, which corresponds to about half the maximum quantity encountered in the experiments above cited, as also half the amount endured by divers (30 to 1,000). The criterion for determining the amount of oxygen needed during immersion has also no scientific basis, inasmuch as when the air has become quite heavily charged with carbon dioxide the quantity of oxygen which remains is amply sufficient to maintain life. On which account the apparatus for the extemporaneous deter mination of the oxygen and the carbon dioxide of the air introduced in the submersibles merits little confidence, and furthermore, being founded on colorimetric reactions, gives results which are not very exact. In my opinion it is possible to determine when it is time to renew the air without employing any instrument. In the experiments on submersibles it has been proven that the crew begins to feel discomfort from the confined atmosphere when the proportion of carbon dioxide reaches 20 to 1,000. To remain after that time within physiological limits, it is proper to put in operation the means of renovation, when the gas which serves as an index shall have reached 15 to 1,000. Calculating upon physi ological data, the quantity of carbon dioxide given off in breathing by a crew in relation to the atmosphere of the submersible, the above proportion of 15 to 1,000 is reached on an average in from 6 to 8 hours, after which a renewal of the air becomes necessary. A criterion of greater approximation may be had by making a calculation for every individual boat. A man, working moderately, as on board a submersible, gives off into the air 23 litters of carbon dioxide per hour. Thus we may establish after x number of hours, that the air contains the aforesaid quota of 0.015, through the follow ing formula, in which v is the number of persons embarked, c is the cubic contents of the submersible : 23Xn:tf=0.015:a?; 0.015 Xc hen0ea?=-23xF 608 Vol. XVII BELLI HYGIENE OF SUBMERSIBLES. Example : Given a submersible of 500 cubic meters (500,000 liters) of air, with 36 persons in the crew : 0.015 X 500,000 _ x= - —o 23X36 that is, we should take steps to renew the air after 8 hours of immer sion or better, 9 hours from the last complete renewal of inside air. VENTILATION. X. METHODS OF VENTILATION. The greatest obstacle to underwater navigation, from the personnel point of view, is the difficulty of remaining inside the boat when it is in a state of immersion. Thus the hygiene of submersibles con sists, above all, in the study of the factors of habitability under all of its aspects. Among these factors the predominant one is the renewal of respirable air. Submersibles make use of two methods of ventilation, natural and mechanical. Those used in navigating above water are the same as the methods employed in the ordinary torpedo -boat; those for navigation beneath the water are proper to the submersible. The means of admitting air, analogous in all the types of sub mersibles, are the following : (a) The hatchway.—This is a means of entrance to the inside of the boat, and at the same time gives ventilation and illumination. One of circular form opens on the conning tower, between the two periscopes, and gives entrance to the engine room. Others, ordi narily three in number, open on the upper bridge, the first and the last into the fore and after torpedo-launching rooms, respectively, the middle one into the electric motor room. The hatchway of the conning tower may remain open when navi gating above water, and the others ordinarily must be kept closed. (b) Ventilation tubes.—Several of these, varying in number, are assigned to the ventilation of the combustion motors and are com parable to the various pumping or exhaust artificial methods. Among these tubes, two rise 3 meters above the upper bridge and are near the periscope tubes; therefore, to distinguish them, it is useful to indicate them by the term " para " periscope tubes (paraperi- scopici). During complete immersion they are closed by means of a sliding valve; but the part which remains above this fills with water which, on returning to the surface, is ejected by means of a jet of compressed air. Two or more serve for the extraction of pases emitted from the accumulators. Other apertures are made in the hull for discharging torpedoes, for the telephonic buoy, for the siren, for radiotelegraphic cables, for periscopic tubes, for the expulsion of gases from thermal motors, No. 4. 609 BELLI HYGIENE OF SUBMERSIBLES. but they have no hygienic purpose and do not serve for ventilation or as passageways. Mechanical ventilating devices are operated by electric motors. As on ordinary boats, the driving out and drawing in of air is necessary, both for respiratory functions and for promoting the combustion of thermic motors, so that the crew benefits by both these factors. In addition to the above-mentioned devices, there is a special one having the hygienic function of carrying off gaseous substances escaping from the accumulators. The provision of air for navigation on board submersibles in some cases is by a detached system, in others a system of centralization, and in still others with two systems operating at one time. The detached system is used exclusively for the exchange of inside air for outside air, and hence it is employed when the boat is in communication with the atmosphere. The centralized system, in addition to the foregoing, performs a second function, i. e., provid ing for the circulation of air inside the closed boat. The detached system, analogous to that employed on the ordinary torpedo boat, employs exhaust and intake ventilators placed in each single com partment, without any intercommunication one with the other. The number of these ventilators, their length, and the location of their outlets is arranged according to regular navy criterion. In any event an exhaust ventilator is necessary in the toilet rooms. The system of central ventilation consists of tubing which leads to all the inhabited compartments and has two openings for each room, one on one side for the introduction of air, the. other on the opposite side for its extraction. At the two extremities the tubing is con nected with two ventilators, the pulsator at the bow, the exhaust at the stern. When the hatchways are open, putting in operation both ventilators at once, the pulsator sucks in the air from the nearest hatchway, and sends it to all the compartments ; the exhaust ventila tor, located at the opposite extremity, carries the air out through the adjacent hatchway. When the hatchways are closed the ventila tors act merely as agitators, putting the air inside the boat into cir culation. The louvers of the pressure ventilators and the intakes of the suction ventilators open in the upper part of the rooms, contrary to the rule of placing the louvers of the pulsators in the lower part and the intakes for the exhausts in the upper part. The systematization of the openings of the upper part is convenient when the centralized system of ventilation is in operation with the boat immerged, because the movement of air remaining confined to the upper strata, the car bon dioxide accumulated below is not disturbed. On the contrary, with the hatchways open, the scope of the ventilation is to completely renew the atmosphere, driving out the carbon dioxide and other im 610 Vol. XVII BELLI —HYGIENE OF SUBMERSIBLES. pure gases. The location of the intakes of the aspirating ventilator in the upper part of the room is unsuitable, for the reason that it leaves in the lower part zones of stagnant air. Under these circum stances, in order to also renew the air in the lower part and remote from the intakes of the fixed tubing, there are installed flexible sleeves which will enlarge the field of aspiration of the ventilators. As in the engine rooms of ordinary vessels, a special system of 1 ventilation is installed in submersibles to further the combustion of the gasoline for the operation of the thermic motors in which a large volume of fresh air, of great benefit to the men, is introduced by electrically driven apparatus : pulsators which introduce the air into the compartment, exhausts which draw the air from the rooms and expel it outside. The quantity of pulsator ventilators is much greater than that of the exhausters, because a large quantity of air is em ployed to drive the products of combustion through the tubes in tended to carry them off. Electric motors are operated in underwater navigation; that is, with the hull completely immerged, and in partial immersion when the " para " periscopic tubes, although out of water, for reasons of safety must be kept closed. Consequently during the operation of the electric motors there is no introduction of air from the outside. It is an essential condition therefore that such motors may go on operating in closed surroundings without prejudice to the health of the crew. From these motors when they are working, there is developed a con siderable quantity of heat, which raises the temperature of the atmos phere. With the motors running while the submersible is immersed, it is not possible to utilize ventilation to lower the temperature of the atmosphere, as on ordinary ships. Instead, three different meth ods are employed for this purpose : One, cooling by means of sea water, another the intermixture of the air of all the compartments, and the third the employment of refrigerating machines. The cooling of the air by means of sea water is accomplished by using a ventilator which sucks the air from the accumulator rooms and conveys it through a tube across the space between the hulls. Here the air gives off its heat and is cooled by the sea water, return ing to the accumulator rooms at a lower temperature. The cooling of the air by circulation is attained by a mixture of the entire atmosphere of the boat, brought about through a system of central ventilation which places in circulation the air from all the compartments in such a way that the hottest air of the electric-motor rooms gives off heat to the cooler air of the other compartments until a thermic equilibrium is reached. The third method, cooling by the refrigerating machines, was at first introduced to cool the batteries of the accumulators and finally was extended to the living places. The air, by means of suction ap No. 4. 611 GALWEY GAS WARFARE. paratus. is made to pass through the refrigerating room, where it is cooled and separated from its water vapor, which is deposited in the form of brine. In the refrigerating room the air passes into circula tion conductors, by means of which it circulates through all the com partments. The plant may also be operating when the boat lies on the surface of the sea with the air from the outside atmosphere pass ing through the refrigerating room. In large submersibles there are two plants, one for compartments forward and the other for com partments aft. This arrangement is very useful hygienically, inasmuch as it lowers the temperature and the humidity of the air and does away with the principal cause of disturbances in confined atmosphere. A special system of exhaust ventilation has been devised for the electric accumulators, which when charging cause the development of toxic gases, which develop, too, although in an appreciably lesser degree, when the accumulators are discharged. The batteries are closed hermetically with air-tight covers to pre vent the gases from entering the atmosphere. For greater safety, the ventilating system draws off the gases that are set free and expels them outward. GAS WARFARE— ORGANIZATION IN PEACE AND WAR.1 By MaJ. W. R. Gal wit, 0. B. E., M. C, R. A. M. C. Gas warfare organization in the British Army at the beginning of the use of this arm was in much the same status as it was in the other allied armies. Responsibilities were divided and policies were constantly changing. Offense measures were first under a branch of the War Office. Defense appliances and troop protec tion fell to the Army Medical Department, in which a new section was created for the purpose. The offense had, as an advisory group, the chemical committee of the Royal Society, composed of eminent scientists, and the antigas committee, also numbering among its members prominent specialists, functioned .in a similar capacity for the defense. In May, 1915, the Ministry of Munitions was formed and took over chemical warfare problems of research and supply, but the antigas department was not transferred from the War Office to the Ministry of Munitions to become a section of the chemical warfare department until October, 1917. At this time a new advisory com mittee —the chemical warfare committee —was appointed. It con sisted of practically the same persons who had been on the former committee. 1Reprinted from the Jonr. Roy. Army Med. Corps, April, 1922. Abstracted by Lieut. G. H. Maokin, Medical Corps, United States Navy. 612 Vol. XVII GALWEY —GAS WARFARE. In 1916 the experimental station at Porton was placed in com mission. Here were carried on the large-scale field experiments and applied research into both offensive and defensive measures. Here were studied the physiological effects of gas poisoning as well as the pathology and the methods of treatment. Abundant proof of the wisdom of the transfer of the antigas department to the chemical warfare department has accumulated since the time that it first became evident that any divorce of de fensive from offensive research was fatal to rapid action and efficiency. At the time of the signing of the armistice the chemical warfare department consisted of the following sections : (1) Administrative headquarters in London, with the chemical warfare and chemical designs committees attached to it. (2) An antigas section at University College, responsible for re search on defensive measures and the manufacture and supply of all antigas equipment. (3) The Porton Experimental Station for field work and applied research on a large scale. (4) A small-scale experimental station at Wembley. (5) Research for special problems at universities and other places throughout the country. Consequent upon the demobilization, the organization went through various times of stress, but was finally reconstituted in its present form. The chemical warfare department is now under the master-general of ordnance and forms a branch of the directorate of artillery. It is a joint organization, serving the needs of the three services —Navy, Army, and Air Force. It is advised on tech nical matters by the chemical warfare committee. Many of the problems of defense are in the fields of hygiene and physiology, but it must be remembered that gas-defense administra tion is not one of medical administration. The following constitutes the author's personal view of the mini mum medical organization required in peace time if the British Army is to be prepared for a future war. The directorate of pathology in the War Office deals more par ticularly with the medical aspects of gas warfare and keeps in touch with its representatives in districts at home and abroad. The assist ant directors of pathology and deputy assistant directors of pathol ogy are charged with keeping in intimate contact with all new work in physiology, pathology, and treatment which will aid in bringing about the most effective care of gas casualties. Similarly, the direc torate of hygiene keeps its representatives, the assistant and deputy assistant directors of hygiene, informed of work on problems of respiration and physical efficiency which bear upon the wearing of No. 4. 613 GALWEY— GAS WARFARE. defensive appliances. The officers mentioned above, in connection with the directorates, should be required to pass on all information * in their respective fields to all medical officers and Royal Army Medical Corps personnel. He feels that every medical officer should be required to go through the Army antigas school or through the experimental sta tion at Porton. As a distinctly medical problem, is mentioned the matter of dis infection of respirators. It is pointed out that there is a real danger of infection of this equipment with a variety of disease-producing germs. It is recommended that either 1 per cent Izal solution or 2£ per cent cresol solution be used asHhe disinfecting fluid. • . Another matter of first importance is the training of stretcher bearers in first aid to gas casualties and the instruction of hospital corpsmen in the treatment of these cases, particularly in the adminis tration of oxygen by the Haldane method to a large number of patients simultaneously. A diagram giving the desirable antigas organization for war, which seems to lend itself to reduction to moderate simplicity, makes provision for the following: At general headquarters, the director of gas services : (1) Offensive, Assistant director of gas services (with Special Brigade R. E.). (2) Defensive, Assistant director of gas services. (3) Central laboratory. At army headquarters: Chemical adviser. Assistant chemical adviser. Army gas school (two-day course for staff officers niul senior regimental officers). At corps headquarters : Chemical adviser. Corps gas school for officers and noncommissioned officers. At division headquarters : Division gas officer. At headquarters, line of communication, under the direction of the assist ant director of gas services (defense) : Chemical adviser. Assistant chemical adviser. Base gas schools. The medical organization consisted, broadly, of one or more casualty clearing stations for each army area, a gas center in each division, and of certain base hospitals set apart for the reception and treatment of gas casualties. It was designed that treatment should be supervised by a consultant, specially conversant with these cases, at the base, and one or more consultants in the forward areas. There was liaison between the medical and gas directorates at gen- 4539—22 5 614 Vol. XVII GALWEY GAS WARFARE. eral headquarters, and the central laboratory for defense research - had a physiologist on its staff. The author suggests that both casualty clearing stations and base hospitals should have special arrangements for disinfection of clothing and for the administration of oxygen. He indicates the necessity for the gas-proofing of motor ambulances as well as aid posts and dressing stations in the next war, and that, further, this new form of warfare is bristling with new problems for the medical department whether on the side of protection or treatment. He gives a diagram of a so-called gas center in a field hospital. It consists, in the main, of three long temporary buildings placed parallel to one another and connected by a walkway. Two of these buildings were fitted up as wards, one for serious cases and contain ing fittings for oxygen administration, the other for slight cases without oxygen installation. The third building contained the receiving, bathing, and dressing rooms. The ward for serious cases was situated between the other two buildings. The buildings pre sent no particularly new features with regard to their interior ar rangement and require no special description here. Benjamin Henry Latrobe, HISTORICAL. BENJAMIN HENRY LATROBE. 1764-1820. THE DESIGNER OF THE FIRST NAVAL HOSPITAL. By W. M. Knits, Lieutenant Commander. Medical Corps, United States Navy. We pay so little attention in general to what is going forward on the scene on which we ourselves are actors that when nov) and then a real story, unadorned by fiction, is presented to us in the succession of its circumstances, we are apt to fancy it too full of incident and contrivance to have passed on the tlieater of actual life. I have mare than once made this observation in reading my old journals of trivial transactions, which had very little but truth to recommend tliem. In this respect we are like actors of dramatic scenes, who are so engaged with their own parts that they hardly ever study the performance of others. We wait till our own act comes, and then go on, as we have accustomed ourselves to do. I have often intended to make the recital of some of my own adventures an amusement of my leisure, but whenever I have at tempted it the appearance of fiction has accompanied many of the most positive facts. Indeed, the general rage for novels, which most frequently recite very common occurrences but which we know to be invented, throws a false reflection upon every relation which at all steps out of the common road. The practice of keeping a regular journal was recommended to me very early in life by my father, merely for the sake of irriting down my ideas with ease and correctness, for he recommended at the same time that I should at the close of every year extract all the generally useful facts and burn the remainder. I have fol lowed his advice at intervals ever since I was a boy, both in writing and burning my journals. Since my arrival in America I have in a great measure altered my plan of a diary into a collection of observations and a record of facts in which my personal interest and actions were not immediately concerned?- B. H. L. 1 Foreword of the Journal of Latrobe. 615 616 Vol. XVII BENJAMIN HENRY LATROBE. Benjamin Henry Lutrobe was the youngest son of the Rev. Benja- mine Latrobe, a clergyman of the Moravian faith, and Ann Margaret Nutis, the daughter of a gentleman of Pennsylvania. The Latrobes were of old French stock, having emigrated to England from France during the persecution of the Huguenots. Miss Nutis had been sent from Pennsylvania by her parents, who were Moravians, to be edu cated in Germany and meeting the Rev. Benjamin Latrobe while there, they were married about the year 1755. The childhood of Benjamin Henry Latrobe which, until 11 years of age, was spent chiefly at school in Yorkshire, was marked for his fondness for drawing, and he early attained a correctness of percep tion and a force and facility of delineation which are generally acquired onty after years of practice. When he was 12, he was sent to Saxony, to a Moravian seminary, where he remained until he was prepared to enter the University of Leipsic where he remained nearly three years. During this time he was a diligent student and devoted himself to the acquisition of that knowledge which he believed would be useful to him in later years. In 1785, when in his eighteenth year, he left Leipsic and spent some months in traveling through Germany. The following year he returned to England and established a residence in London. He adopted architecture and civil engineering as a profession, and con centrated all his energies upon the acquisition of practical informa tion concerning these sciences. His father's friends in London were influential, and he gained ready access to the best society of England, forming friendships and acquaintances with the distinguished scien tific men of his day. He became intimate with the celebrated Smea- ton,2 who, although retired from the active practice of his profession, gave him the benefit of his advice and vast experience. 3 John Smeatoo, an English civil engineer, was born at Austhrope, near Leeds. York shire, June 8, 1724, and died there, October 28, 1792. At an early age he showed so Inclination toward mechanical contrivances and when 16 he became apprentice to a philosophical instrument maker, and in 1700 set up In business on his own account. The following year he began a course of experiments on a machine of his own In vention to measure a ship's way at sea. In 1753 he was elected a Fallow of the Royal Society. In 1755 the Eddystonc Lighthouse was burned down, and Smeaton was Intrusted with the task of rebuilding it. Operations were begun in August, 1756, and completed in October, 1759. This lighthouse remained in use until 1882, when it was replaced by a new structure. Besides improving various mathematical instruments used in navi gation and astronomy, he carried on experiments in regard to other mechanical appli ances, among thorn investigations of wind and water mills for which he received the Copley medal of the Royal Society in 1759. After this, Smeaton was employed on many works of great public utility, tie made the River Calder (In Yorkshire) navigable; planned and executed the Forth and Clyde Canal in Scotland, constituting a waterway for traffic passing between the Atlantic and the North Sea. He improved various har bors : designed and erected several bridges. He built a steam engine at Austhrope. and made experiments with it to ascertain the power of Newcomen's engine, which he brought to a greater degree of perfection, both in Its construction and power. Snieston spent much of his leisure in the study of astronomy, for which purpose he fitted up an observatory in his bouse. No. 4. BENJAMIN HENRY LATBOBE. 617 In 1788 Latrobe entered the office of Mr. Cockerell,8 one of the leading architects of London, where his classic education, his skill with the pencil, his profound mathematical knowledge, and his ac quaintance with the architectural features of the great buildings of Germany and France gave him a decided advantage over the other young men employed there. In this office he soon acquired a prac tical knowledge of drafting and architectural calculation, and, be lieving himself competent to commence the practice of his profes sion, he opened an office of his own. He met with immediate success and was soon appointed surveyor of the public offices in London. In 1790 Latrobe was married to Miss Lydia Sellon. As a result of this marriage two children were born, a son and a daughter: In 1793 Mrs. Latrobe died. Her death affected him profoundly; and although he was at a period in his life when his professional rela tions in London offered him every inducement to remain in that city, he determined to leave England. He had taken a great interest in the new doctrines of government which were then being widely dis cussed. Taking the side of liberal principles, he was among those who looked to America as the scene of that great experiment in government which has since been so successfully accomplished; and as his mother had been born in America where her relatives still resided, he determined to cross the Atlantic and to practice his pro fession in the United States. He completed his business in England, declined the office of surveyor to the Crown, with a salary of £1,000 per annum, disposed of his property, and on the 25th of November, 1795, he left England. On the 20th of March, 1796, after a passage of nearly four months, Latrobe landed at Norfolk, Va.4 After remaining several months at Norfolk, he went to Richmond, where he was employed to superintend the erection of a penitentiary which he had designed and which the legislature had determined to build. He designed many dwellings which were erected in Rich- "Cockerell, Samuel Pepys ( 1754-1S27), architect. His mother was a daughter of John Jackson, the nephew and heir of Samuel Pepys, and through her Cockerell became the representative, and Inherited many interesting relics, of the great diarist. Cockerel] soon rose to eminence in his profession, and in 1796-1798 he rebuilt the church of St. Martin, Outwich, London, his most important work. He also designed several large and handsome residences. One of his sons, Charles Robert Cockerell (17S8— 186:!) became a far more distinguished architect than his father. * In those days the world moved slowly. No change had yet been made in methods of transportation and communication. It took as long to travel from London to Rome as it did in the time of Julius Caesar. It Is interesting to note In this connection that the nineteenth century was destined to be the period of the world's greatest progress, due to the development of rapid transportation and communicHWon accomplished by steam and electricity, in which some of the sons of B. H. Latrobe took an active part. B. H. Latrobe, Jr., was for years the civil engineer of the Baltimore & Ohio Railroad, and another son, John Hazlehurst Boneval Latrobe, was the head of that organization's legal department. 618 Vol. XVII BENJAMIN HENRY LATROBE. mond, Norfolk, and Petersburg. He was employed to examine and report upon the feasibility of the construction of the Dismal Swamp Canal and the improvement of navigation of the Appomattox and the James Rivers. His services as a geologist and mineralogist were frequently in demand, and he devoted some time to a study of the geological features of Virginia. He traveled much throughout the State. His acquaintances were numerous, his talent appreciated, his society sought; ample occupation was afforded him, and he had no reason to regret the loss of the prospects which he could have enjoyed had he continued to reside in England. On one of his many excur sions through Virginia he visited President Washington, at Mount Vernon, an account of which will be found in his journal.5 He was a great admirer of beauty, and his tribute to Miss Custis, the grandchild of Martha Washington, who had been adopted by Washington, shows his high appreciation of that lady's good looks. He writes as follows : " Miss Eleanor Custis has more perfection of form, of expression, of color, of softness, and of firmness of mind than I have ever seen before or conceived consistent with mortality. She is everything that the chisel of Phidias aimed at but could not reach." In 1798 Latrobe removed to Philadelphia, where he designed a new building for the Bank of Pennsylvania. This building is the work which permanently established his professional reputation in this country, and his performance is all the more remarkable in that he did not have access to a single book on architecture from which to obtain the proportions of the type to which the building belongs. The vessel in which his library had been shipped to America had been taken by a French privateer, so that for several years he was without a single architectural authority and was obliged to rely solely upon his memory and his taste. In Philadelphia he met the lady who became his second wife, Mary Elizabeth Hazlehurst, daughter of Isaac Hazlehurst, who was the business partner of Robert Morris, the great financier of the American Revolution. His marriage was a happy one and resulted in the birth of two sons, B. H. Latrobe, jr., and J. H. B. Latrobe. Latrobe's next professional undertaking was the construction of the first waterworks for supplying the city of Philadelphia with the water of the Schuylkill by means of a steam engine, which pumped the water into reservoirs, from whence it could be distributed through the streets of the city. It was the first time that such an enterprise had been attempted in America, and Latrobe was looked upon as a visionary when he proposed the scheme. Unfortunately, 2 The Journal of Latrobe. D. Appleton and Co., New York, 1905. No. 4. 619 BENJAMIN HENRY LATROBE. Major L'Enfant,4 a French engineer, the designer of the plan of the city of Washington, had disappointed the people of Philadelphia in the home which he undertook to build for Robert Morris, and in the city assembly rooms, for which a large sum of money had been raised by popular subscription and squandered. The house, for Mr. Morris was never finished, the incomplete structure eventually be ing torn down, and the assembly rooms never rose above the founda tions. L'Enfant had scarcely left the city when Latrobe made it his home and attained public notic« by the two works that he at once commenced— the Bank of Pennsylvania and the city water works. The bank building was easily understood by the inhabitants, but the city waiter supply was at first incomprehensible, ranking with the schemes of L'Enfant, and they believed they were justified in transferring at once to Latrobe, because of his profession and French name, all the unpopularity of L'Enfant. People were not satisfied with treating him and his designs with contempt. Per sonal abuse was heaped upon him. Difficulties were thrown in the 'On the 16th of July, 1790, nn act was passed by Congress authorising the President to appoint commissioners to survey, under his direction, a district of territory, not ex ceeding 10 miles square, at some place on the River Potomac, between the mouth of the Eastern Branch and Conococheague. The President, " with that consummate Judgment which distinguished his career, fixed upon just the one spot in the entire range of terri tory prescribed by Congress which commanded the threefold advantages of unfailing tide-water navigation, convenient access to Baltimore and other large cities, and superb natural sites alike for public buildings and the varied wants of a populous city." To prepare the plan of the future city, the commissioners appointed Charles Pierre L'Enfant to be their engineer. He had come to America as an officer in the French line in 1777, was wounded in the assault of Savannah by D'Estaing, was taken prisoner, was exchanged In 1782, became; major of engineers in the American Army In 1783, was sent to France by the Society of the Cincinnati to arrange for the engraving of its gold badge, and, being accomplished In many ways, on his return he was employed, in 1789, to prepare the Old City Hall in Wall Street, New York, for occupation by Congress after the adoption of the Constitution. Brought into notice in this way, L'Enfant seemed to be the proper person to prepare the plan for the new city ; and at once proceeded, with the assistance of Andrew Elllcott and others, to execute the work. It was Elllcott who established the meridian of Washington, the intersection of which by an east and west line Is marked by the Capitol. L'Enfant appears to have had carte blanche In the matter of planning the future city ; nor had Peter the Great more control In this regard, when he laid out, on the marches of the Neva, the grand avenues of the Russian capital, than the French major of engineers— who in some respects Imitated him — when he traced, on the swampy ground of the Tiber, a small stream long ago diverted into the city's sewers, the plan of a city, which in the stately magnificence of its public buildings has long surpassed the city of the former Czars. When the map of the future Washington was finished and the public sales were to be effected L'Enfant refused to submit his work to public inspection ; his excuse being that certain neighborhoods would be seized by speculators, and shanties rnn up where he designed palaces to be constructed. Such not being General Washing ton's view of the matter, the commissioners took possession of the maps, and L'Enfaut's further services were dispensed with. In 1812, he was employed by Mr. Madison to plan a fort on the Potomac below Washington, and later Mr. Monroe offered him a professorship at West Point, which he did not accept. As an old man he wandered about the streets of Washington in peculiar dress. He died In 1825, taking his place In the ranks of the vast host of forgotten bene meritos. He was burled on the farm of William Dudley Digges at Green Hill, Prince Georges County, Md., where his declining years were spent as a guest, but his remains were removed 84 years later (Apr. 28. 190!)) to a site in Arlington Cemetery In front of the Lee Mansion. 620 Vol. XVII BENJAMIN HENRY LATROBE. way of his procuring laborers. Injuries were done to the buildings by unknown persons. No argument could convince the public of his good intentions. Popular dislike of Latrobe advanced with the progress of the work until, when the pipes were laid in the streets and the steam engine finished, affairs became so strained that he was threatened with violence. In fact, the situation became quite melodramatic. On the afternoon of the day when the steam engine was in readi ness, by Latrobe's orders the hydrants were left open. In the middle of the night, with three friends and one of his workmen, he went to the waterworks, kindled a fire under the boiler, and set the pump in motion. Everything worked as he anticipated, and the inhabitants of Philadelphia awoke to see the streets of their city flooded by water from the gushing hydrants. The successful operation of the waterworks established his reputa tion firmly in Philadelphia. With a wife and a growing family to support, he endeavored to increase his professional activities. He was engaged to survey a route for a canal to connect the Chesapeake and Delaware Bays, and shortly after the commencement of the sur vey he became interested in the construction of the Capitol in Wash ington, to which city he had made frequent visits. As shown by his correspondence, he was thrown with the leaders of society in Washington, and the following extracts from letters written by him throw light upon the customs of the times. Washington, Nov. 24, 180Z. Having employed my morning in my business I went to dine with the Presi dent. His two daughters, Mr. and Mrs. Madison, Mr. Lincoln (Attorney Gen eral), Dr. Thornton, a Mrs. Carter from Va., and Captain Lewis, (the Presi dent's Secretary) were in the party. The dinner was excellent, cooked rather in the French style, (larded venison), the dessert was profuse and extremely elegant, and the knic-knacs, after withdrawing the cloths, profuse and number less. Wine was served In great variety, from sherry to champagne, and a few decanters of rare Spanish wine. The conversation of which Mr. Madison was the principal leader, was incomparably pleasant, and though Mr. Jefferson said little at dinner besides attending to the filling of plates, which he did with great ease and grace for a philosopher, he became very talkative as soon as the cloth was removed. The ladies stayed till five, and half an hour afterward the gentlemen followed them to the tea table, where a most agreeable and spirited conversation was kept up until seven, when everybody withdrew. It is a long time since I have been present at so elegant a mental treat. Literature, wit, and a little business, with a great deal of miscellaneous remarks on agriculture and building, filled every' minute. There Is a degree of ease in Mr. Jefferson's company that everyone seems to feel and to enjoy. At dinner Mrs. Randolph was asked by Mr. Carter to drink a glass of wine with him and did so. Mr. Jefferson told her she was acting against the health law. She said she was not acquainted with it, that it must have passed during her absence. He replied that three laws governed his table —no healths, no politics, no restraint I enjoyed the benefit of the law. and drank for the first time at such a party only No. 4. 621 BENJAMIN HENEY LATROBE. one glass of wine, and, though I sat by the President, he did not invite me to drink another.' ' Practically all the letters written by Latrobe are In tlie possession of his descend ants. An explanation of this remarkable fact is to be found in the following quotation from an address on " the Capitol and Washington at the beginning of the present cen tury." delivered by John H. B. Latrobe before the American Institute of Architects in Washington, D. C, Nov. 16, 1881. " The materials from which much of the foregoing has been prepared have been fur nished by the letter books and portfolios already mentioned. That I should have letter books from a date that knew not pnss, copybooks, or manifold writers, needs an explana tion that might be put Into n footnote were it not connected with one who, if not an architect, was an artist, a mechanician, and a scientist, and in this way near of kin to the profession whose members are before me. I refer to Charles Wilson Peale. About the year 1802 he invented what he called ' a polygraph,' the essential parts of which were a light horizontal rod, with jointed sockets at each end to hold common quill pens. This was connected with parallel motions ; one traveling on the upper part of the Inclined desk, while the other was suspended from a frame above it—the two permitting the pen rod to move the width and length of a sheet of paper. Two of such sheets of paper were held flat by spring bars at their upper edges. The movement of the two pens being thus made identical, while the left-hand one, held by the writer, wrote the letter, the right-hand one wrote a duplicate original, which was placed in the desk drawer, until a sufficient number bad accumulated to be bound and Indexed. Of these originals I have IS volumes, covering the period from 1803 to 1810, inclusive. Unfortunately, they form but one side of the correspondence which embraces all conceivable subjects. In my father's frequent changes 9f residence the other side has been lost. I do not know if there is a polygraph still in existence. If not, this notice will, at any rate, make a matter of recerd of a most ingenious device, the Invention of one whose name is insepa rably connected with the history of art in America." In a letter to Mr. Jefferson dated Oct. 2, 1803, Latrobe, speaking of the polygraph, says : " I am not yet entirely master of the motion so as to write exactly the same hand which a single pen produces ; but in an hour's practice I learned to write with the same ease and rapidity as with a common pen. I doubt not you have heard of the machine, and perhaps you possess one of them. What I have written on the other side Is a specimen of the truth with which a copy is made." That Jefferson owned a polygraph is Indicated by the following news Item which appeared iu the Washington Post of May 28, 1922. " The polygraph, with which Thomas Jefferson wrote his letters and manuscripts, has just been restored to a working condi tion in the workshop of the Rouss physical laboratory at the University of Virginia by the mechanical ingenuity of A, J. Weed. "This instrument was presented to the University of Virginia in 1875 by Col. Thomas Randolph. In his letter of presentation he states that Jefferson used this polygraph during the last 20 years of his life. " Careful measurements were made of all broken parts and new pieces were substituted in their places, but all of the original parts which could be used were cleaned and re- finished. " When closed the polygraph presents the appearance of a substantial mahogany box. 10 by 17 inches in size and 5 inches high. On opening the cover a push pin is dis closed, by pressing which the central portion of the case can be loosened from the bot tom on one side and stood in an upright position with the bottom and top of the case resting flat on the table. "Upon withdrawing a sliding bolt the writing mechanism can be brought forward. This consists of two penholders of silver mounted on a wood bar In such a manner that while they are free to be moved in any direction the motions of both are identical. This is made possible by two pantographs, one end of each being attached to the bar carrying the two pens. One pantograph controls the horizontal motion of the pens and the other controls their vertical movements. When one pen is dipped into nn ink bottle the other pen makes a corresponding movement in a duplicate bottle. "The preservation of so many of Jefferson's papers and letters is due to the fact that he used this instrument and therefore wrote them in duplicate." In 1798 Latrobe had met in Washington Dr. William Thornton, a man of great genius, but not an architect, who had drawn the plan of design of the Capitol which had been selected by General Wash ington as the one to be followed in its erection. Thornton was of 622 Vol. XVII BENJAMIN HENRY LATEOBE. English descent, born in the West Indies. He became the first super intendent of the Patent Office. He invented a paddle-wheel steam boat, and in later years accused Fulton of having wrongfully de prived him of it. When Latrobe met him he was one of the commis sioners appointed to superintend the construction of the Capitol. Latrobe makes the following remarks concerning this meeting in his journal : " I spent the afternoon with the doctor. One of the first subjects introduced was the plan of the Capitol, of which he had a ground plan and east elevation. . . . With freedom, but without giving offense, I objected to both plan and elevation, and offered to give the doctor a drawing in perspective of his design which I trusted would convince him of his errors. But he never sent me the necessary materials." In 1803 President Jefferson invited Latrobe, then in Philadelphia, to undertake the supervision of the construction of the Capitol, and he accepted the appointment to the office of Surveyor of Public Build ings mentioned in the following letter : Washington] D. C, March 6, 1803. Sib—Congress has appropriated a sum of $50,000 to be applied to the Public Buildings under my direction. This falls, of course, under the immediate business of the Superintendent, Mr. Munroe. whose office Is substituted for that of the Board of Commissioners. The former post of Surveyor of the Public Buildings, which Mr. Hoban held until the dissolution of the Board (at $1,700 a year) will be revived. If you choose to accept it you will be appointed to It and would be expected to come on by the first of April ; Indeed if you could make a flying trip here to set contractors at work immediately, in raising freestone, it would be ex tremely important, because it is now late to have to engage laborers and the quantity of free stone which can be raised, delivered and cut in the season Is the only thing that will limit the extent of our operations this year. I shall set out tomorrow for Monticello and shall be absent 3 weeks, but shall be glad to receive there your answer to this. Accept my friendly salutations and regards. Th. Jefferson. Latrobe's first step on receiving his appointment was to examine the work that had been done and to see how far the plans yet un finished could be carried into execution. In his journal he says: " I called for drawings to guide my opera tions. The President gave me a plan, and Dr. Thornton gave me another. They were copies of each other and both perfectly use less; neither of them agreed with the work as founded or carried up, and there were no details whatever. In the superintendent's office no drawings existed. To speak plainly, the design was evi dently the production of a man wholly ignorant of architecture, having brilliant ideas, but possessing neither the knowledge neces sary for the execution nor the capacity to methodize and combine the various parts of a public work. In some respects the plan, as No. 4. 623 BENJAMIN HENRY LATROBE. far as it indicated what was intended, was impracticable, and in all respects it was so inconvenient and often useless in its arrange ments that I despaired of correcting it. However, I gave it several days of severe study, and then stated to the President that I could not undertake its execution. He consented to alterations. I pro posed consulting Dr. Thornton. The President said it was unneces sary and would be useless. Having in the course of a week, how ever, formed and reduced to drawing all my proposed alterations, I called on the doctor, to whom I believed much to be due on the score of delicacy. I procured an interview, at which, after much argument and heat, he at last consented to admit my ideas into the plan. But the next day he called on me, and, with much irritation and using language offensive and uncivil, he recanted." 8 Latrobe not only encountered opposition on the part of Doctor Thornton, but all who hud been engaged in the work opposed him. Even- effort was made to injure his reputation. If he suggested an alteration in the plans, if he pointed out a defect, if he showed the impracticability of executing a part of the design, he was sure to bring upon himself a host of assailants. Congress especially was opposed to any change in the plans that had been approved by General Washington. Several times Latrobe was on the point of resigning from his office, and was only prevented from doing so by the firm and unwavering support that on all occasions he received from the President. Shortly after his appointment Latrobe commenced the construc tion of the south wing of the Capitol, of which the foundation had been already laid. The whole design of the interior of this wing is his work, the exterior, of course, was built in conformity with the design of the north wing, which was built under the direction of Doctor Thornton and which was so far completed by the year 1800 that Congress moved to Washington and occupied it. At the time of his appointment to the office of Surveyor of the Public Buildings, the design and supervision of the construction of the buildings at the navy yard in Washington was put into Latrobe's hands at an extra compensation of $1,000 per annum. He designed the workshops and supervised all the improvements within or in con nection with the yard during his residence in Washington. "The result of I-atrobe's visit to Doctor Thornton Is best explained by the following letter, dated Feb. 27, 1804 : TO THB PRESrDBNT OF THE U. S. Dear Sib :— I judged very ill In going to Dr. Thornton. In a few peremptory words, he in fact told me that no difficulties existed in his plan but such as were made by those who were too Ignorant to remove them: and though these were not exactly his words, his expressions. Ills tones, Ills manner and bis absolute refusal to discuss the subject, spoke his meaning more strongly and offensively than I have expressed. In Mr. Jefferson's reply, dated the following day, he says : " De.ik Sie : I am very sorry the explanations attempted between Dr. Thornton and Jourself over the manner of finishing the House of Representatives have not succeeded." 624 Vol. XVII BENJAMIN HENRY LATKOBE. The navy yard gate," which was long admired for its excellent taste and the beauty of its proportion, is an example of his art. It was by reason of this appointment as civil engineer of the Navy De partment that Latrobe was requested a few years later, to design the plans for the first naval hospital. Latrobe moved his family from Philadelphia to Washington in 1807 and established a residence in what was known as the "Navy Yard House," where they resided until the spring of 1812. From notes left by one of his sons, John H. B. Latrobe. we quote the following : 10 " My earliest recollection of my father and mother dates from the Navy Yard House. The occasion was their appearance when dressed for a ' Drawing Room ' to which they were going at the President's. I remember well a tall striking-looking person. 6 feet, 2 inches high in fact, in black, wearing knee breeches and silk stockings with silver buckles in his shoes, erect as a soldier, and without being handsome in the face, of a distinguished carriage. My mother was as dis tinguished in her appearance as my father was in his. She was a very tall woman, five feet, 8 inches and had always been celebrated for the beauty of her figure. Her face was in no ways remarkable. She had been a leading belle in Philadelphia, and had the air of a woman of fashion of that day. On this occasion she was dressed in white satin with a long train, and wore a turban of spangled muslin with a gold crescent, fastening a heron's upright plume. They must have been regarded as a verv noble looking pair. " In addition to my father's other accomplishments he was an excellent musician, and my mother was celebrated for her voice, cultivated when she was a girl, under the instruction of the best masters in Philadelphia of that day. " The Navy Yard House was an attractive one for the society of Washington in 1808 or thereabouts. Mr. Madison was a frequent visitor, Chief Justice Marshall. Mr. Foster, the British Minister, Mr. Serruvier, the French Minister, Madam Dushkoff, the wife of the Russian Minister, Robert Fulton, Doctor Mitchell. Gilbert Stuart, the painter. " Another visitor was the dearest little woman in the whole world, my mother's bosom friend, Mrs. Juliana Miller, one of the most diminutive of her sex, but one of the best and truest. " Both my father and mother were fond of society. My father was a man of great conversational powers and rare accomplishments. My mother was a brilliant talker and a wit." A description of Latrobe is contained in the following letter written by John H. B. Latrobe to his cousin John Frederick Bate- man. • " The entrance to the navy yard Is through a spacious gateway of hewn stone "— October 2, 1809. Recollections of Samuel Breck, edited by H. E. Scndder, Porter, and Coates, PhUadelpbia, 1877. 10John H. B. Latrobe and His Time — 1803 to 1891. By John E. Sommes. No. 4. 625 BENJAMIN HENRY LATROBE. Baltimork, Maryland, S June, 1370. My dear Oocsin : I Imve forwarded to your London address a copy which I made of Reinhurt real's [Rembrant IVale '.'] very poor portrait of my father, the only merit of my work being that it is pretty nearly a facsimile. My father was six feet, two inches in height, of erect and military carriage. In repose his face was almost dull. In conversation it was all animated and his listeners thought him handsome. His hair was very dark, with a slight wavy curl. He spoke most living languages, German, French, Spanish, Portu guese and Italian with fluency and understood most dead ones, Greek and Latin thoroughly, and knew a good deal of Hebrew; was n clever poet and an accomplished musician. In 1811 the south wing of the Capitol was completed and the fur ther progress of the public buildings was suspended for want of appropriations to carry them on, the approaching war with Great Britain being alleged as the reason for curtailment in the expendi tures for this particular object. The work at the navy yard, how ever, was carried on upon a larger scale than ever. From the following extract of a letter written by Mrs. Latrobe to her friend, Mrs. Juliana Miller, 185 Walnut Street, Philadelphia, we learn that in the spring of 1812 the Latrobes moved from the Navy Yard House to a residence on Pennsylvania Avenue. Washington, February 17, 1812. . . . We were last week at a dance given by the officers of the Enterprise [subsequently celebrated for her engagement with and capture of the ' Boxer ' in 1813] in the great sail loft of the Navy Yard; the insufferable smell of tar gave me a headache or I should have spent a pleasant evening. We are about to remove from our present habitation to a larger house on Pennsylvania Avenue. We shall be very near the Hauiiltons " and not far from the President's and what is equally agreeable, we shall be near the market and can offer you, my dear Juliana, a much better accommodation than when you were last here. J. H. B. Latrobe, commenting on this period, cites his personal recollection of the city as it was in 1812 : Pennsylvania Avenue was little better than a common country road. On either side were two rows of Lombardy poplars, between which was a ditch often filled with stagnant water, with crossings places at the intersecting streets. Outside of the poplars was a narrow footway, on which carriages often intruded to deposit their occupants at the brick pavements on which the few houses scattered along the Avenue abutted. In dry weather the Avenue was all dust ; in wet weather, all mud ; and along it " The Royal George" an old-fashioned, longbodied four horse stage—either rattled with members of Congress from Georgetown in a halo of dust, or pitched, like a ship in a sea way, among the holes and ruts of the national highway. The Capitol itself stood on a steep declivity, clothed with old oaks and seamed with numerous gullies. Between it and the Navy Yard were few buildings, here and there over an arid common; following the amphitheater of hills from the southeast around to the heights of Georgetown, houses few and far uPaul Hamilton. Secretary of the Navy. 626 Vol. XVII BENJAMIN HENRY LATROBE. between, Indicated the beginning of the present city. The Patent and Post Office, in one iiugh un-ornamental, barn-like brick edifice, occupied the place of their marble successors ; and at the other end of the avenue, the ' White House ' had become a conspicuous object with the adjacent public offices. Still following the amphitheater around the eye caught a glimpse of Alexandria and rested upon the brond expanse of water where the Eastern Branch joined the Potomac, with Greenleafs Point between the two, on which the great tribe of the Shawnees once lit its council fires and had its fishing ground. Additional extracts from two other letters written to Mrs. Juliana Miller by Mrs. Latrobe throw some light upon those times : Washington, June 27, 1812. The theater is nearly opposite to our present residence. They have full houses. Many of the members of Congress, never (I suppose) having seen a piny, avail themselves of it. There was a terrible riot last evening, owing to the musicians refusing to play " Hail Columbia." One of them called out " Play Foster's March,'' upon which Sam Ringgold threw a bisket at him, and another gentleman, Mr. Howard of the Senate, caught him by the collar and dragged him over the railing. A terrible battle ensued which ended in an apology from Warner nnd an order to start up " Hail Columbia ", which was played so long a time that most probably none of the audience will ever wish to hear it again. Washington, December 14, 1812. On Tuesday a very splendid ball was given to the Navy Officers —Hull, Morris, Stewart, etc. My husband could not be absent as he holds an office in the Navy Department, and I was not sorry we went, as it is not likely that I shall ever witness such another scene. At about five in the evening my husband came home and informed me that we must immediately illuminate our house, as the account of a victory gained by Commodore Decatur had just arrived. My house in ten minutes was prepared for lighting up, and we prepared for the ball. The avenue was very brilliant on our way to the Capitol Hill, and the company assembling, the crowd was immense. Mrs. Madison was there, but not the President. The evening went on with crowded dancing and treading as usual upon the toes and trains of those who did not dance; when about ten o'clock a loud huzza announced the arrival of young Archibald Hamilton, who had that moment appeared with the colors of the Macedonian.™ He was " Commodore Decatur cruising in the United States, a 44 gun vessel, on Sunday. October 25, 1812, In lat. 29° N., long. 29° 30' W., sighted a large sail to the southward and eastward. The stranger was running down a little free, while the American ship was on a wind, standing towards the chase, which was soon ascertained to be an enemy. The latter having come within a league, hauled up, and passed to windward, when each party was enabled to see that they had a frigate to oppose. The stranger now wore and came round on the same tack with the United States, keeping away sufficiently to get within reach of her long guns, when she hauled up on an easy bowline, with her mizen-top-sail aback. At this moment the distance between the two ships a little exceeded a mile when the Englishman opened his Are. Finding the enemy on his weather quarter, Commodore Decatur delivered his larboard broadside, wore round, and came up to the wind on the other tack, heading northerly. It was observed that all the carronade shot fell short, the enemy doing very little injury by his Are. Having passed her antagonist, the United States delivered her starboard broadside, and wore again, bringing her head once more to the southward, or on the same tack as the enemy, both ships steering rap full [with every sail drawing], with their miien topsails aback, and keeping up a heuvy cannonade. In this manner the action continued about an hour, the English vessol suffering heavily, while her own fire inflicted very little injury on hpr antagonist. At length the stranger's mlzen-mast came down over his lee quarter, having been shot away about ten feet above the deck. He then fell off. and let his foresail drop, apparently with a wish to close. As the ships got new No. 4. 627 BENJAMIN HENRY LATROBE. borne into the room by many officers. Good little Mrs. Hamilton, his mother, stood by me, and was so much agitated at the sight of her son that she must have fallen, had I not stepped forward and offered her my arm. The young man sprang into her arms, his sisters threw their arms around him, and the scene was quite affecting. The colors were then held up by several gentlemen over tlie heads of Hull, Morris, and Stewnrt, and " Hail Columbia " played and there were huzzas until my head swayed. The aforesaid colors were then laid at the feet of Mrs. Madison. Oh tempora ! Oh mores ! This was rather overdoing the affair. together, the shot of the American vessel did fearful execution, the forecourse being soon In ribands, the fore and main-topmasts over the side, the main-yard cut away in the slings, and the foremast tottering. The United States now filled her mizon-topsail, gathered fresh way, and tacked. As the stranger was drifting down, nearly before the wind, and was almost unmanageable, Commodore Decatur had no difficulty In heading up high enough to cross his wake, which he handsomely effected, with his people still manning the larboard guns. At the time the United States filled her mlzen-topsail, In preparation for stays, it is said that the enemy, under the impression she was about to run away, gave three cheers, and sot a union jack in his main rigging, all his other flags having come down with the several spars. When, however, the American ship was seen luffing up to close, the jack was lowered, and resistance ceased. As the United Slates crossed the stern of the English ship, the firing having ceased on both sides, she hailed and demanded the name of her antagonist, and whether she had submitted. To the first interrogatory. Commodore Decatur was answered that the ship was the Macedonian 38. Captain Carden, and to the second, that the vessel had struck. On taking possession, the enemy was found fearfully cut to pieces, having received no li'BS than a hundred round shot in his hull alone. Of three hundred men on board him, thirty-six were killed, and sixty-eight wounded. The Macedonian was a very fine ship of her class, mounting, as usual, 49 guns, completed them hnd not the war interrupted them. After the declaration of war he was encaged In the works required by the U. S.

This fund was to be augmented by all the fines imposed on naval officers, seamen, and marines. The commissioners were, moreover, authorized by this bill to pro cure a suitable place, or places, proper for naval hospitals, and, if the necessary buildings could not be obtained with the site, they were empowered to have such erected, " with a due regard to economy, giving preference to such plans as with most convenience and least cost would admit of such subsequent additions as the funds would allow and circumstances require." In a report 15 dated February 2, 1813, submitted to the honorable William Jones, Secretary of the Navy, on work directed to be under taken since 1803, is the following, which indicates that Latrobe pre pared the plans for the first naval hospital which it was proposed should be erected in Washington. I have been ordered by the Department to report a plan of the proposed naval hospital and having devoted to the subject very close attention. I sub mitted a design, report and estimates, which are, I presume, with the Commis sioners appointed by law. I also attended the late Secretary to the site ap proved by him in this city for the erection of the buildings. As to the Report and Plans, I have copies should the originals be mislaid. This service was considered to be a duty not necessarily belonging to my engagement with the Navy Department. All which is respectfully submitted. B. Henry Latkobe, Civil Engineer, Navy Department.

Major Latour in his works mentions him In the following words :— "That very morning, (December 28, 1813), the engineer Henry S. Boneval Latrobe had established, under the Are of the enemy's artillery, and a cloud of rockets, a 24 pounder on the left of the battery No. 1 on the line. This gun dismounted one of the field pieces which the enemy had placed in the battery on the road." The principal engineer. Major Latour, being engaged on the first and principal line of defense, Gen. Jackson ordered Capt. Latrobe to construct a second line, between the first and the city to which to retreat in case of defeat. The manner in which he per formed this duty gained him the entire confidence of the General. . . . He had his share in the labors and glory of the 8th of January, and on the retreat of the British to their ships, he was ordered to erect such works in advance as should render their return with reinforcements impracticable. He was not then 22 years of age. Peace restored him to his civil occupations, and he projected works and buildings at New Orleans which soon gave him the lead In his profession. In 1815 he wu appointed by the U. S. Government a commissioner with Com. Patterson and Mr. Dn- plessis, the collector, to select a site for a lighthouse, so essentia] to the safe navigation of the river. His design and report on that work .... will give to professional men a full idea of bis early talents and taste. . . . It is remarkable that, till his last illness, his temperance and activity had secured him from all sickness in the dangerous climate of New Orleans ; and on the 24th of August he wrote to assure his family that there need be no apprehension on hit account. A few days afterwards he fell a victim, perhaps to his security. . . . Henry S. Latrobe was 24 years old on the 19th of July last. » Miscellaneous Letters. Navy Department Library, vol. 1, 1813, No. 78. No. 4. 633 BENJAMIN HENRY LATROBE. Though *wo yftars hnve elapsed since the passing of this law [the bill to establish naval hospitals], the end it was intended to effect has never yet been accomplished. The talents of that able engineer, Mr. Lntrobe, were employed by the Secretary of the Navy (Mr. Paul Hamilton) for the design ing of aa .architectural plan of the buildings to be erected. This plan was admirably calculated for the erection of permanent and convenient edifices, to which, from time to time, as exigencies might require, or the hospital fund admit, additions might be made, so that when the whole was completed it would present one entire and perfect building. In this plan he had exceed ingly well «ombtned the requisite economy, so far as compatible with the ultimate object of the law, with that simplicity, elegance, and convenience, which characterize all the works of this master architect This plan met with the "warmest approbation of the secretary of the navy, but was objected to by the other two commissioners, for those qualifications which ought to have entitled it to their favorable opinion, viz., its permanency and stability. The business therefore fell through, and the whole plan proved abortive. The great need of establishing naval hospitals at this time was emphasized by Surgeon Barton, who, in his Treatise on Marine Hospitals, says: The time has arrived, when we must view the establishment of extensive navy hospitals, as an event by no means remote or improbable, but in fact as necessarily connected With the augmentation of the navy, and the preserva tion of the health and lives of the officers and seamen who compose it. An extensive and energetlck naval establishment, cannot possibly be con ducted without the institution of publick marine hospitals for sick and hurt officers, seamen, and marines ; and asylums connected with them, for superan nuated or decrepit pensioners of the service. We have no such institutions at this time, in any part of the United States. The very Inconsiderable estab lishments in some of our seaport towns, limited in extent, and unsystematl- cally organized, deserve not the appellation of hospitals. In some of these there are medical officers, whose ability and experience would certainly enable them to superintend and govern very extensive establishments, if the appro priations by Congress for the building of such hospitals, were adequate to defray the expense of them. The spirit of exertion and enterprise then of these surgeons, would, if unrestrained by the necessity of such circumscribed expenditure in their operations redound very much to the interest and welfare of the service. Every naval station in the United States, presents a noble site for the erection of marine hospitals. Those of St. Marys and Norfolk, on the southern coast ; the central ones of Philadelphia and New Tork ; and those of New London, Newport, and Boston, on the northern coast, are peculiarly well adapted for hospital establishments. The liberality and munificence of a gov ernment cannot find more worthy objects of their favour, than that class of its citizens who voluntarily expose their lives and fortunes to the most immi nent perils and afflicting accidents —for the safeguard, the protection, and defence, of the honour and prosperity of our country. And when we view the present want of extensive institutions for the care of sick sailors, we can not but hope, that the Imperious necessity for their establishment, will, before long, elicit the attention of Congress; particularly when we advert to the known impolicy of such deficiencies. They are impolitick, because it is natural to suppose, that men will be deterred from entering a service, in which no sufficient provision is made for alleviating the distresses it is liable to produce. 634 Vol. XVII BENJAMIN HENRY LATROBE. Nothing causes seumen to discover alacrity, promptitude, and faithfulness, in the performance of their severe and arduous duties, or contributes more to reconcile them to the comfortlessness, the hazardous chances and accidents, to which they are constantly liable in the service — than a certainty of being attended humanely and ably, by the superintendents of a medical department replete with every comfort and convenience for the sick and afflicted. Every one who has had an opportunity of mixing with seamen on ship-board, must be aware of this fact. While, on the other hand, the neglects, irregularities, or inability, of the medical ollicers. never fail to create discontentment and disgust. In the petition to the lords commissioners of the admiralty, made by the delegates of the English fleet at Spithead, in the ever memorable mutiny that prevailed in his Britanick majesty's navy in the year 1797, when the command of the whole fleet was usurped by the seamen, in consequence of what they deemed their grievances, one of the principal articles referred to the neglect of their sick on board the ships, and the embezzlement of such neces saries and comforts as were allotted by government to their use. This alarming mutiny could not be quelled, until these grievances were absolutely relieved; and it was deemed prudent and expedient to issue new orders and instruc tions from the office of sick and wounded seamen, respecting the medical de partment, the strict observance of which was required of the surgeons. Indeed, I have myself seen, among a number of sick seamen with whom I was left in charge at the navy yard of this place [Philadelphia], where they were necessarily huddled into a miserable house, scarce large enough to accommo date the eighth part of their number —a spirit of impatience, and even of revolt, in those who were able to discover it, that was calculated to contrive the most serious injury for the service. So wretched was the hovel, and so destitute of every necessary comfort for sick persons, in the charge of which I was left witli thirty patients, (although a surgeon had been between five and six years on this station) that every man who gathered sufficient strength, and was successful in getting an opportunity to effect his escape, absconded Immediately. The replies of these men, when I addressed them respecting the desertion of their comrades, were strongly expressive of their wearisomeness and impa tience of such disgraceful accommodations; and their disgust and sense of grievance were uttered in terms, that convinced me the intention to desert was not confined to a few of them. Undoubtedly Surgeon Barton's remarks had some effect on those in authority, for in the following letter we see that the Secretary of the Navy, the honorable Benjamin W. Crowninshield, evidently de sired to expedite the building of the hospitals. Washington, January 1st, 1815. The Hon""" the Secretary of the Navy. Sib : The designs of the Navy Hospital, are now within a few hours of being finished, and will be presented to you tomorrow morning about one o'clock- Having delivered the only perfect copies in my possession to Mr. Hamilton, when Secretary of the Navy, I have been obliged to make out a new set of drawings from my first sketches, and have devoted all my leisure since my late very pain ful illness to their completion. Mr. Dallns requested me the day before yesterday to ask of you the favor to meet me at his office in the Treasury. If tomorrow (Friday) this favor could be granted to me. I shall be much obliged. No. 4. 635 BENJAMIN HENRY LATROBE. The designs of that part of the Marine hospital which is proposed to be first built, I have seen in possession of the Commissioners of the Navy within a few months. 1 am very respectfully, Yr. Obed. Servt. B. H. Latrobe. No evidence exists that Latrobe's design was ever used. The first naval hospital at Washington was established in a building rented for that purpose near the navy yard. This was succeeded by one estab lished at the navy yard, which was discontinued in 1843, when the sick were transferred to marine headquarters. The Civil War caused these accommodations to be insufficient, and a temporary hospital was established in the grounds of the " Government Hospital for the In sane." and used until October 1. 1866, when the naval hospital on Pennsylvania Avenue near the navy yard was completed.18 From November, 1815, until Latrobe severed his connections with the Capitol, the records show many protests from the commission ers against the slow progress of the work and against him giving too much attention to private matters, for Latrobe had many private interests and enterprises which he was endeavoring to manage con temporaneously with his work on the Capitol. Both he and the com missioners were fretting, he, because he felt under too much restraint, and they, because he gave, according to their ideas, too little time and attention to the public work. April 24, 1816, Congress abolished the commission of three who had been put in charge of Government buildings and authorized the appointment of a single commissioner at a salary of $2,000 per annum, Samuel Lane, of Virginia, being appointed to fill this posi tion. On October 31, 1817, Mr. Lane made Capt. Peter Lenox, clerk of works at the Capitol against the protest of Latrobe. This appointment was the cause of Latrobe sending in his resignation to President Madison, who does not seem to have raised any objec tion to this action, but referred it to the commissioner, through whom it should have come. The commissioner answered as follows : November 24, 1817. B. H. Latrobe. Sib: Having seen your letter to the President of the United States resigning the appointment of Architect of the Capitol, I have to inform you that your resignation is accepted and to request that you will deliver to Captain Lenox all the books, plans, instruments, etc., belonging to the public in your pos session. Yours. Samuel Lane, . Commissioner of Public Buildings. "Notes on Naval Hospitals, Medical Schools, and Training Schools for Nurses, by J. P. Ontewnod. passed assistant surgeon.

There he was engaged to build the Exchange on Gay Street and to supervise the construction of the cathedral, which had been started in 1805. The building of the Exchange was commenced in 1817 from a design made by Mr. Latrobe while he was in Washington. The cathedral, in point of size and solidity of execution, is his greatest work. The Bank of Pennsylvania was long considered as the most beautiful ; but while it does not yield to the cathedral in taste or execution, it is of course inferior in size. After his removal to Baltimore, Mr. Latrobe decided to go to New Orleans with a view to completing the waterworks there which had been commenced by his son and in which so much of his fortune had been invested. Leaving his family in Baltimore, he went to New Orleans by sea in 1819 and began assembling the engines which he had had built in Baltimore. In 1820 he retnoved his family to New Orleans, with the intention of making that city his residence until the waterworks were completed and their success certain. His work progressed rapidly. The engine and pumps were in stalled and in two weeks the entire work would have been done and water flowing through the streets, but on the very day that he was engaged in superintending the laying down of the pipe con necting the pumps with the Mississippi he was stricken with yellow fever and in a few days he was dead. He was buried beside his son in one of those cemeteries in New Orleans which he had described so vividly in his journal. EDITORIAL. EDITORIAL STAFF. Lieutenant Commander W. M.

In connection with the article on " Yellow fever in St. Thomas with special reference to its spontaneous elimination," by Lieut. E. Peterson, Medical Corps. United States Navy, which appears in this number of the Bulletin, it seems proper to recall the remarks concerning yellow fever made by George E. Vincent, president of the Rockefeller Foundation, in his review of the activities of the Foundation in 1921. President Vincent summarized as follows the salient facts about yellow fever : " Probably prevalent in Aztec times in Mexico and Central Amer ica; for last two centuries a dreaded scourge in Mexico, the West Indies, Central and South America, frequently invading North Amer ican ports and causing thousands of deaths in the lower Mississippi Valley; fact of transmission of bite of female Stegomyia mosquito established by American Army Medical Commission under Reed in Cuba, 1900-1901; Habana and Cuba freed from fever by Gorgas, who organized antimosquito measures 1901-2; example followed in Rio de Janeiro and Vera Cruz, 1903-1909; Panama Canal Zone successfully protected by same methods, 1904^1906; fear that canal traffic might carry disease to Far East and the confidence of Gorgas that fever could be eliminated led to appointment in 1916 by Inter national Health Board of special commission to survey seed beds of infection ; Gorgas, head of commission, recommended a campaign of extermination; during delay caused by war, Noguchi, of Rockefeller Institute of Medical Research, visited Ecuador, Peru, and Yucatan, isolated germ believed to be inciting cause of yellow fever, and pre pared vaccine and serum, 1918-1920; yellow fever commissions or ganized in Central American countries, Colombia, Venezuela, Ecua dor, and Peru; intensive campaign, 1918-1919, under Connor elimi nated disease from Guayaquil, the chief endemic center; 1920, com mission sent to West Coast of Africa to investigate suspected areas; with occasional outbreaks, most of them traceable to places in south 637 638 Vol. XVII EDITORIAL. em Mexico, the fever gradually gave ground ; late in 1920 Mexican Government organized commission and invited cooperation of Inter national Health Board. " Up to the beginning of 1921 experience with Noguchi's vaccine and serum indicated that the former when properly administered affords a marked protection against attacks of yellow fever, and that the latter if it is used on or before the third day of the onset of the disease reduces the mortality in a striking way. Data reported dur ing last year confirm these conclusions. In Peru, of a group of 50 nonimmune soldiers who were being sent into an infected district. 25 were vaccinated and 25 were left unvaccinated. Twenty of the latter group contracted yellow fever, while no case of the disease occurred among members of the former. Of 12 yellow-fever patients in Belize, Honduras, who were treated with serum on or before the third day of the attack, 11 recovered. Until yellow fever is eradi cated at its sources, the vaccine and serum promise to be most valu able means of prevention and cure. " With the entrance of the Mexican Government early in 1921 into the yellow-fever campaign the prospects of successful advance brightened. The chief remaining sources of infection were attacked. During 1921 Ecuador, Honduras, Nicaragua, and Costa Rica were not invaded by the disease. Guatemala reported no case after Febru ary 2; Salvador's last case was recorded February 15; by July 16 Peru was free, as was British Honduras in November. From north ern Brazil cases were reported, but the situation was being dealt with by the Government. It was gratifying to the Foundation to be able to advance money for continuing the campaign in Peru at a time when Government funds were not quickly available. The advantages of having resources which could be immediately mobilized in an emergency were strikingly demonstrated. It was another example of the efficiency of a unified plan of cooperation. The outlook is encouraging; it is too early to proclaim a complete victory, but the purpose to push the fight against yellow fever remains steadfast." (W. M. K.) BUBONIC PLAGUE. In connection with Surgeon McCoy's excellent lecture on some fea tures of plague which was printed in the last number of the Bciae-tin. it is interesting to read some remarks on plague by Dr. M. Neveu- Lemaire, which appeared in La Presse Medicate of May 31, 1922. After describing the primary and secondary endemic foci of the disease and the manner in which it has affected the colonies of France in the past, the writer continues his discussion, in part, as follows: Since the most remote times, it has been noted that epidemics of plague were always preceded by a considerable mortality among the No. -t. 639 EDITORIAL. rats of the locality. Rats are not, however, the only animals capable of harboring the bacilli of plague. Mammals which are capable of spreading the infection are sufficiently numerous. They are particu larly the rodents—mice, marmots, and the spermophiles. Mammals belonging to other classes, such as the dog, the cat, monkeys, sheep, the hog, and the donkey may convey the disease. However, the great disseminators of bubonic plague are two species of rat, found in all parts of the world, the sewer rat and the black rat. The sewer rat, Epimys norvegicus (mus decuvum.ua) , is also known by the name of gray rat, city rat, or brown rat. It is longer than the black rat ; its coat is fallow gray on the back, grayish on the belly ; its ears are the length of one-third of the head ; its tail thick at the base, is a little shorter than the trunk. An interdigital membrane unites the claws at their base. This rat, more common than the other, originates from the Orient and, about two centuries ago, in vaded the Occident following the great famines which raged in the Asiatic regions. It is very prolific and resisting, chasing the black rat before him ; it lives particularly in the country and in the interior towns, inhabiting especially the sewers, cellars, and the subsoil. It is important as a propagator of an epidemic, because it emigrates readily, swims easily, and can disseminate the malady through the country from village to village and from city to city. There exists a brown or black variety Epimys norvegicus maurus, which must not be confused with the following species. The black rat, Epimys rattw (Mus rattus). is known as the domestic rat or garret rat. Smaller than the preceding variety, it is distinguished by its black coat on the top, gray underneath : by its ears, longer than half its head; by its tail, slim at the base and a little longer than the trunk; and, lastly, by the absence of an inter- digital membrane. Probably of Asiatic origin, it has existed in Europe since the Middle Ages, lives chiefly in the upper stories of houses, but also on ships and on docks where foodstuffs are kept. Equally as prolific, it emigrates less than the preceding species, and swims less easily. A variety of this species, Epimys rattus alexan- drinus, which resembles in color E. jwrvegicva, although it has a blacker back and a whiter stomach, is found in certain warm regions, such as Italy and Egypt. Plague is transmitted from the rat to man by means of the flea. The role which this insect plays was established in 1898 by a French physician, P. L. Simond. Fleas are temporary parasites, and each species is generally adapted to a particular host, but the specificity of this parasitism is not absolute, and the majority of fleas can pass from one animal species to another, which explains the transmission of the malady from rat to man. In an investigation by A. W. Bacot. 34 different 640 Vol. XVII EDITORIAL. species of fleas were found on various rats, but these rats were not the normal hosts of the majority of the species of flea. Ordinarily about a dozen species of flea are found on rats. Among them, two species play an important role in the transmission of plague—Cera- tophyllus fasciatus and Xenopsylla cheopsis. A flea commonly found on man, but rarely on the rat, Pulex irritans, can play a role in the transmission of plague from man to man. "6'eratophyllus fasciatus is distinguished from the other two spe cies by the presence, back of the prothorax, of a dark denticulated cape, called the thoracic comb. This flea normally lives on the rats in Europe, in India, and in Egypt; it transmits plague from rat to rat and can remain infected 45 days, according to Gauthier and Eaybaud, and 67 days, according to Bacot. It seldom attacks man : therefore is not especially dangerous. " Xenopsylla cheopis possesses no comb ; it resembles a great deal the flea of man, even though its color is a little clearer ; the presence of a bristle which is inserted before the eye is the point which dif ferentiates it from the latter. This flea is a normal parasite of the rat in all warm regions, but it can also live and be reproduced in the temperate countries. H. Violle has observed it in great proportion in Paris on the sewer rat, even during the cold season. While it is the habitual parasite of the rat, it readily bites man and passes readily from one host to another. This species is the principal propagating agent of bubonic plague from rat to man. It remains infectious from 36 to 43 days, and the plague bacilli live in much greater number in its organism than in that of CeratophyUus fasci atus or of Pulex irritans. " Pulex irritans is man's own parasite, which can, nevertheless, be. exceptionally found on various domestic animals and even on rats; it is a cosmopolitan species, abundant during the hot season in the temperate climates Its role in the transmission of plague from man to man is certain, although the bacilli are less numerous and live a shorter time in the flea's stomach than in that of Xenopsylla ckeopis. Zirolia and Verjbitsky have observed plague bacilli in the dog flea, Ctenocephalus canis, and they have succeeded in experimentally transmitting the malady with the aid of this insect. Verjbitsky has obtained analogous results with the cat flea, Ctenocephalus felis, but on the contrary, experiments made by the English commission to India with this same species have been negative. A rat flea of Asia, CeratophyUus anisus, is able to transmit plague from rat to rat, but it will not bite man. Lastly, the mouse flea, Leptopsyfla musculi, can harbor plague bacilli; and by means of it Verjbitsky has succeeded in transmitting the malady from rat to rat. No. 4. 641 EDITORIAL. Experiments have also been made with bedbugs. Cimex lectularius, which is easily infected by the plague bacilli, but a large quantity of the bedbugs so infected die. In the case of the surviving ones, the bacilli multiply and the intestinal contents of the insect remain viru lent at the end of 48 days. Cimex rotundatus acts in the same man ner, according to the experiments made by Cornwall and Menon in India in 1917, and this species remains infected as long as 38 days after the bite. However, in the case of bedbugs, the development of the plague bacilli is a great deal slower than in the case of fleas and their role in the transmission of the plague must be very slight, if it exists at all. As it is known that certain rats are the reservoirs of the plague bacilli, and that the fleas which they lodge, more particularly Xenop- sylla ckeopis, are the transmitting agents, it is quite simple to ex plain the evolution of the epizootic among rats and of human epi demics. When a rat dies of the plague, the fleas which it lodged leave its corpse and attach themselves to other rats, as soon as they find them, which they contaminate. Thus the malady among rats is spread. In the regions where plague is endemic, in India for example, the fleas have the opportunity, when rats diminish follow ing an increase in their mortality, to bite the natives, thus trans mitting the malady to them, so that the human plague is always asso ciated with an epizootic in rats. According to Violle, 1 cubic centimeter of plague blood contains 100,000,000 bacilli, so that one flea which bites a sick rat can accu mulate probably 5.000 germs in its stomach cavity. But by what mechanism does the flea transmit those bacilli when it afterwards bites an animal or individual? By analogy with what occurs in ma laria, it was at first believed that the plague bacilli could be found in the salivary glands of the flea and that they were thus inoculated with the saliva, but this hypothesis had to be abandoned as un true. It was determined that after a flea had bitten an infected animal no plague bacilli is found in that portion of the digestive tube between the mouth and the proventricule, but they are nu merous in the stomach, and the fact that they are so numerous proves that they have multiplied, but the valve formed by the proventricule prevents them normally from leaving the stomach and being inocu lated through the medium of the buccal portions of the flea. It has been noted that the flea, while it bites, drops from time to time its excrement on the skin, and this excrement, containing numerous plague bacilli, is infectious. This is not, however, the most common manner of transmission. In 1914 Bacot and Martin, experimenting with Xenopsylla cheopis and Ceratophyllus fasciatus, observed that a certain number of these insects suffered from an obstruction of the alimentary canal. Later investigations demonstrated that in these 642 Vol. XVII EDITORIAL. cases the plague bacilli had been multiplied to such an extent in the proventricule and in the stomach that they had formed a compact mass, incapable of being evacuated. Fleas so infected are more famished than normal fleas. When they are placed on a host they suck with vigor, but the aspirated blood can not pass through the stomach. Therefore, when the effort ceases, the blood, which has been aspirated and has come in contact with the plague bacilli, is contaminated, and as it is regurgitated into the wound by force infection occurs. Regurgitation being produced many times in succession, the result is that the number of inoculated bacilli is augmented. In the case of bedbugs, the anatomical dis position of the digestive tube not permitting the blockage which has just beeen mentioned, the excrements only are infectious. Some authors admit that several bites are necessary to transmit the plague, but Swellengrebel has succeeded in infecting 43 guinea pigs out of 45 by one bite of Xenopsylla cheopis. How can the appearance of an epidemic far away from the orig inal home of the malady be explained? Let us suppose that a ves sel, having been contaminated in an oriental country, arrives at an European. African, or American port. Black rats infected with plague have slipped aboard with the cargo; a great number of them have died during the voyage and their bodies have remained at the bottom of the hold ; those which have survived may have left the vessel upon its unloading and may have gone to die in the market places near the docks and the warehouses, where native rats are usually found in abundance. The latter are contaminated by in fected fleas which have left the imported plague-infected rats, and a veritable epizootic is started among them. The majority, fright ened by the mortality among them, emigrate and take refuge in dwellings, or they in turn contaminate, through the medium of their parasites, the domestic rats living in garrets and under the roofs of houses. Fleas leave the latter, and finding no other rats to bite, the greater part of them having died and the survivors having emigrated, fall upon man, whom they contaminate. Thus have started a great number of epidemics of plague which have raged at different epochs in diverse regions of the globe. The prophylaxis of plague, as that of yellow fever, can be effica cious, when the knowledge of the etiology which has been acquired is applied. In order to prevent plague from being spread a great distance, it is first necessary to refer to certain international meas ures. Each country must take the precautions necessary to prevent the scourge from spreading, and this general prophylaxis must con sist, above all, in the destruction of animal carriers of virus and of the vectors of the pathogenic germ : that is to say, of the rats and the fleas. The means of deratization are many; they consist, either No. 4. 643 EDITORIAL. of destroying the rodents by means of virus, of traps, or of toxic substances, or by causing them to perish in depriving them of all that can serve as food or shelter. The destruction of fleas and bedbugs is also obtained by different processes; the insecticides most commonly used are carbon disulphide and oily substances, such as petroleum, naphtha, etc. When an epidemic has been discovered, in spite of tbe precautions which have been carefully taken, the individual must then protect himself. This individual prophylaxis is especially necessary for per sons called upon to administer to the sick. Besides the precautions used for all contagious maladies, one must be protected, moreover, from the bites of fleas by wearing a one-piece garment, fitting closely at the neck, at the wrists, and at the ankle, similar to the contrivances which are used by mechanics or aviators. The ■wearing of a mask is recognized as being the only means of efficacious protection against the pneumonic plague, and certain types of masks, used against gas during the war and conveniently modified, could be utilized to that effect. Finally, preventive vaccinations, the technique of which need not be dwelt upon here, should be administered not only to the hos pital personnel and to men engaged in deratization, but to all the inhabitants of an infested locality, (w. m. k.) ON FAULTS IN WRITING. Not long ago, Dr. George H. Simmons, editor of the Journal of the American Medical Association, was called upon to give an ad dress as president of the Chicago Institute of Medicine. He selected as his subject " Medical periodical literature.'1 upon which he is well qualified to speak, because of an acquaintance of nearly 30 years with medical journalism. He began by reviewing the growth of the medi cal periodical in the United States. When Oliver Wendell Holmes was chairman of a committee of the American Medical Association on medical literature, in 1848, only 20 medical journals were published in this country. The number had risen to 230 in 1903. but it has since declined to 120. Doctor Simmons notes " a distinct change in the type of papers appearing in medical journals to-day as compared with 20 years ago. The therapeutic article of the past, replete with favorite prescriptions, often proprietary in character, has given way to scientific contributions on therapeutic methods, on pharmacology, on pathology, on etiology, on methods of diagnosis, on prophylaxis." Although the number of medical journals has decreased in late years, the volume of writing for publication has not undergone any dimuni- tion. for the Journal of the American Medical Association is now receiving about 1.500 manuscripts a year, exclusive of the papers sub mitted to the sections of the annual meeting. It seems that about 644 Vol. XVII EDITOKIAL. three-fifths of the manuscripts voluntarily offered are returned, and Doctor Simmons devoted the greater part of his address to a consider ation of the reasons for the rejection of the majority of the papers submitted for publication. One reason for rejection is lack of space. Some of the papers received are excellent both in the matter treated and in the manner of presentation, and there is no doubt about their acceptability. Many papers are too long, but one that is informative, that presents new facts or practical information, is not returned if fairly well written, though it may be necessary, with the author's help or ap proval, to shorten or revise it. The question of the proper length of a paper, like Einstein's theory as to space and time, is a matter of relativity. A paper of 500 words may be long; one of 5,000 may be short. Undue length is a common fault, and Doctor Simmons finds three chief reasons for it. The first is " rambling," due to the absence of a plan, so that the author repeats himself and meanders to reach a given point. As a remedy, cross headings are recommended, not only because in a paper of any length they are of assistance to the reader, but because the task of introducing them reveals to the writer defects in the logical arrangement of his matter. If the proper be ginning is not apparent, Doctor Simmons recommends the author to "go right to the subject without preliminaries; to begin in the middle if necessary ; when the end is reached the difficulty of the be ginning will often have disappeared. The second cause of undue length is verbosity, which is to be remedied by revision. When revising a manuscript one ordinarily finds many words, phrases, clauses, sentences, and occasionally even paragraphs that can be struck out without detriment to the meaning. Such deletions not only save space but improve the style and help the reader. The third fault is the tedious discussion of nonessential details. In an extreme form this fault is displayed by papers in which the author, who has a new fact or observation to make, buries it under a mass of material which often takes the form of a long historical introduction. The real remedy for the defects which Doctor Simmons sees in paper after paper received at the editorial office of the Journal- of the American Medical Association is, in his opinion, a more careful study of the art of writing and a thorough revision of all papers submitted for publication. In support of this he quotes Sir Clifford Allbutt's method, as described in his book, Notes on the Composition of Scien tific Papers. The plan of this well-known medical writer is first to put down ideas and facts on slips of paper and sort them under headings; then to make a first draft and revise it; then a second and No. 4. 645 EDITORIAL. revise it; then a third and revise it; and then to put the whole away for at least a week " in order that the final reading may he done with refreshed attention." It may be noted that this method was also employed by Lafcadio Hearn in all his writings. Sir William Osier wrote in much the same way. During an inspection of some of the manuscripts in the Osier library, Doctor Simmons was able to trace one article through its various stages: First there were notes on odd bits of paper, evidently written at odd moments: then there was a rough outline on the paper in long hand; then the first typewritten copy, with interlineations, transpositions, and deletions; next the second typewritten copy, which had been considerably modified ; and, finally, the third typewritten copy, which had been sent to the printer. "If." Doctor Simmons asks, "this is the method of the masters, what about the rest of us? " (w. m. k.) PAI.NFIT. HACK AND FEKT. A symptom which is most difficult to treat is pain in the back and in the feet. It is a symptom commonly encountered at sick call, especially if some distasteful duty such as coaling ship is impending, and is a condition prone to be exaggerated. Where objective symp toms, such as involuntary protective muscular spasm and periarticu lar swelling, are absent, advice regarding proper methods of walking and standing is all that is indicated in the way of treatment. For a patient without objective symptoms who complains that he can not perform his duties, a routine back or foot treatment which keeps him either flat on his back in bed or occupied with an intensive course of corrective exercises should be prescribed. The malingerer, or rather the exaggerator, as most of them are. tends either to progress rapidly toward a cure or to a request for return to duty. In a case of this sort, if the condition proves to be more serious than at first it was believed to be. no harm has been done by this treatment : and if the patient be a malingerer, it will serve as a warning to others appearing at sick call with similar motives. Pain in the back and in the feet comprises the principal complaint of a large majority of patients seen in orthopedic consultation and often occurs in both localities in the same patient, which in itself suggests some associated etiological factor. If organic disease can he ruled out and there is no history or evidence of definite trauma, the condition may be due to faulty posture resulting from lack of muscular tone, actual muscular weakness, overweight, or habit— as walking with the toes turned out. A healthy adult instinctively stands correctly if there is nothing to prevent him doing so. The aborigines never were instructed in the proper methods of walking or standing, yet the posture was such that we can profitably study 4539—22—7 646 Vol. XVII EDITORIAL. it and learn much therefrom concerning correct bodily mechanics. Faulty posture is often the price paid for civilization. Where muscles are inefficient, either from misuse, lack of tone, or weakness, the erect posture is partially maintained by ligaments primarily intended for another purpose. Pain, which is nature's warning that something is at fault, is the result. If this warning be disregarded, nature calls into play a protective spasm of the muscles about the affected part which stiffens the joint and enforces rest. It is the primary function of ligaments to maintain the struc ture and relation of the elements constituting the joint in opposition, and to limit the extremes of motion ; therefore, when the erect posi tion is maintained without the proper use of the muscles, the indi vidual must employ the ligaments to a certain extent for this pur pose. This explains the abnormally acute curve in the lumbar spine and the everted foot often seen in individuals complaining of pain in the lumbar region and in the feet. In the erect posture, the lower portion of the spine and the tarsus are most affected by gravity when there is a general lack of tone to the muscular system. Less weight is carried above the lumbar spine, and what is carried is supported at a better advantage, as the spinal column is more vertical. The other joints entering into the main tenance of the erect posture are the hips and knees, both of which have a greater excursion of motion in locomotion, thus, temporarily at least, relieving the strain from the ligaments which on standing or sitting are not held at their extremes of motion. This explains the frequency of symptoms in the spine and tarsus. In the treatment of these conditions the cause of the muscular relaxation must first be investigated. Frequently the lack of mus cular tone is only a manifestation of a general atonic condition. The patient is often one who is not making a success in life, is some what overweight, has possibly a transient glycosuria, and is not par ticularly active. When the cause of the atonic condition has been determined, one should endeavor to relieve the affected parts from strain by the prevention of weight bearing, after which nature can be assisted in her repair of the damage done by such an agent as physiotherapy. When all evidence of strain has disappeared, exercises without weight bearing should be begun in order to mobilize the affected joints as much as possible. Instruction in the proper mechanical use of the body should be given the patient at this time in order that, after all symptoms of strain have subsided and the stiffened joints have been mobilized, he may know how to hold himself erect and walk properly when weight bearing is finally permitted. Exercises with weight bearing are then to be taken up in an attempt to strengthen the weak muscles. These should not be con No. 4. 647 EDITORIAL. fined solely to the muscles affected, although most attention should! be directed toward them, for, if the tone of the general musculature can be improved, the delinquent muscles will be more apt to re spond. The use of such apparatus as back braces and foot braces should be discouraged in these purely postural cases except as an aid to maintain the proper posture until the patient can retain it himself, (j. w. w.) ON THE PREVENTION OF CARDIAC DISEASES. In late years much effort has been devoted to the prevention of tuberculosis and infant mortality, and now the prevention of dis eases of the heart and of the circulatory system is beginning to claim its share of attention. Statisticians have disagreed as to whether or not diseases of the heart and of the circulatory system have increased during the past several decades, but there are in the United States a great multitude of persons in various age groups afflicted with such disease. It has been stated that if it were possible to bring together every per son in the United States in whom cardiac disease had been definitely diagnosed, we would assemble sufficient cardiacs to equal or possibly outnumber the population of the city of Chicago. If we were to add to this number the persons in this country who suffer from arteriosclerosis or from chronic renal disease, we might have a cardio- nephritic population larger in size than that of the city of New York, which is now estimated at 5,753,151. An average of 2 per cent of the persons examined by life-insurance companies are rejected each year because of a variety of organic heart defects. In connection with the examination of men who were drafted into military serv ice in the recent war, it was reported that of 2,400,000 examined 5 per cent showed organic cardiac defects. The role which heart diseases have played in causing poverty and adversely affecting the lives of entire families because of the crip pling of the wage earners is difficult to estimate, but it no doubt con stitutes a very substantial and serious factor in the social lives not only of the several million suffers from these diseases but among their dependents as well. The studies of various men recently pub lished indicate the necessity of more intensive study of a number of occupational groups which are particularly subject to industrial hazards. Dr. Louis I. Harris, who has contributed to the Nation's Health recently several articles dealing with the prevention of cardiac disease, believes that such special occupational studies would reveal a very much higher percentage of cardiac defects in a number of industries than was found to prevail among insurance applicants or men drafted into military service. There is fairly definite evi 648 Vol. XVII EDITORIAL. denoe that in men employed in the iron and steel mills, especially when their work brings them in close proximity to the various types of furnaces or processes which subject them for comparatively long periods to high temperatures, the incidence of myocarditis is con siderable. It would be of great value to learn more about the preva lence of organic disease among stationary and marine firemen, as well as to determine from among the great mass who are commonly desig nated as " laborers " the relation of physical strain or exposure to excessive heat and other factors present in the various occupations of the laborer, to the development of organic cardiac disease. Un fortunately for science, the Navy can throw little light on this point because of the comparatively short time a fireman remains at this arduous work—promotion soon separates him from the coal shovel and slice bar— but the point is worth keeping in mind. It is definitely known that heart diseases result from focal infec tions, also from the various infectious diseases, as well as from per verted functioning of various organs possessing internal secretions. Cardiac and arterial diseases are most intimately related to syphilitic infection. Among the commoner causes of organic heart disease one finds a variety of toxic agents incident to faulty metabolism or to lack of care as to personal hygiene and toxic agents arising as a result of various diseases as well as those that occur in industries. Long-continued physical strain is an important factor. In an indirect way, mental and nervous strains, excesses of various kinds, as well as other factors in the home or industry which induce fatigue may act as indirect causes of cardiac disease. Preventive medicine is particularly concerned in the early recog nition of cases in which any one of the numerous causes may have operated to produce damage upon any part of the heart or the vascular system, so that such persons may be shielded from these causes and those preventive measures applied which are appropriate to meet the problem of reducing the incidence of cardiac diseases at the various stages of life. In instituting preventive measures, education of the masses must be conducted with energy and consistency, and it must be education of a character that shows in terms of dollars and cents that it pays to safeguard the human machine. A great deal will be accomplished when people can be persuaded to submit to periodic medical exami nation. Special study must be given to the question of the protection of adolescents, as it is during this period that vital changes are being effected in the human organism. Special attention must be given those recovering from infections or other diseases which predispose to cardiac disease, and to those who are recovering from acute cardiac disease or cardiac breakdown. No. 4. 649 EDITORIAL. Encouragement should be given to the establishment of work shops for cardiacs so that work of a suitable character, done under proper medical supervision, could be performed by those having cardiac defects who are under compulsion to be self-supporting. There is need of factory medical inspection of the most thorough kind which will appraise the harmfulness of the various industrial factors in their effects upon the heart. The short work day should be encouraged wherever severe mus cular exertion or other factors producing marked fatigue may be. found in the industrial environment. It is extremely important to warn those with a tendency toward the development of diseases of the heart and of the circulatory system against the reaction of mental strain, worry, rush and bustle, unrestrained zeal and am bition, and of the far-reaching effects which they produce directly or indirectly upon the vascular system and upon the heart. Last but not least, provision must be made for the control of car diac disease during childhood. The foregoing constitutes more or less an epitome of the tentative program of the Department of Health of the City of New York for the prevention of cardiac diseases, which program promises in time to reduce the rate of prevalence of organic heart disease in that city just as tuberculosis and infant mortalit}' have been reduced. (w. M. K.) IMMUNITY AGAINST MEASLES. Although in the year 1921 there occurred only 26 deaths among 1.694 patients originally admitted to the sick list in the Navy for measles, the death rate in civilian communities, especially among children under 6 years of age, is high; in fact statistics show that it equals the death rate from smallpox before vaccination was intro duced. The introduction of vaccination by Jenner in 1796 was an epoch-making event in the history of preventive medicine and, as we all know, the practice has brought about a diminution in the in cidence of smallpox. According to the Latwet for March 25. 1922, it seems that we may be on the eve of a similar turning point in the prevention of measles, as Dr. Rudolf Degkwitz (Deutsche medi- zmviche IVochemcrift, January 5, 1922) has found it possible to con fer immunity by the injection of serum from a patient convalescent from measles. Doctor Degkwitz's observation, however, is not new, for Nicolle and Conseil (Bull de U Soe. Med. d. hop. de Park, April 12, 1918) used serum from a child, the first case of measles in a family of four children. Two of the other children were not treated, but a child 2 years of age was given serum from the first case taken on the seventh day of convalescence and 10 days after the first 650 Vol. XVII EDITORIAL. symptoms. The other two children developed measles in three or four days, but the 2-year-old escaped infection, although exposed to the first child and later to his two brothel's who had developed the disease. Richardson and Connor {Journal American Medical Association, April 12, 1919) also report experiments in passive im munity on six children who were protected against measles by intra muscular injections of the serum of a patient convalescent from measles. In the March number of Medical Science, Dr. J. D. Rolleston re views the literature on this subject up to Degkwitz's latest article in which he gives his conclusions based upon the inoculation of more than 1,700 children. As we all know, the prodromal stage of measles, before the initial rise of temperature and malaise make their appearance, is highly infectious, and it is impossible to detect and isolate infected cases early enough to prevent the spread of the disease. By the time the diagnosis is made, all nonimmunes who have been in contact with the patient may have been infected. Degkwitz has proved that by inoculation of a small quantity of serum derived from a convalescent patient, all the contacts can be protected completely or to such an extent that they only develop the disease in its mildest form. The success of the inoculation depends upon the time in the prodromal stage when it is given and the amount of serum injected. The earlier in the incubation period the child is inoculated, the smaller will be the dose necessary to protect him, and vice versa, until a stage is reached when if the inoculation is postponed too long no amount of serum will produce immunization. Up to four days from the date of infection, 2.5 cubic centimeters of the serum is sufficient to protect a child under 4 years of age from measles. This dose Degkwitz calls the unit of protection. On the fifth to sixth day, 5 to 6 cubic centimeters, or two units, will be necessary. On the seventh day much larger doses will not afford certain pro tection, and on the eighth day inoculation is useless, as even large doses, 30 cubic centimeters, neither prevent the onset nor influence the course of the disease. According to Degkwitz the usual period of incubation is four days; and applying the data given above, he advises the following routine: If in a case of measles the rash is just appearing, all children who have been in contact with the patient should be immediately inocu lated with 2.5 cubic centimeters of serum from a convalescent patient and they will be protected. If the rash is already 24 to 48 hours old, 5 to 6 cubic centimeters must be used to protect the other children. In both cases the immunized children may safely be allowed in the room with the patient. If the rash is 72 hours old, No. 4. 651 EDITORIAL. 8 to 10 cubic centimeters of serum should be given, and in all prob ability about two-thirds of the contacts will be protected. No ill effects of inoculation have been observed by Degkwitz, who is always careful to exclude syphilis or tuberculosis in the donors. His results have been uniformly pood within the limits stated. The question of the duration of the immunity is still uncertain; 33 days is the shortest observed, but more than a year has been reached in other cases. Degkwitz's work opens a field for experimentation. Immune human serum is difficult to obtain on a large scale; therefore it is highly desirable that an immune animal serum be developed, which might be produced in any quantity required, and it would be of value to extend these experiments to adults with a view to reducing the incidence of measles among them. (w. m. k.) O.N FILAKIASIS. It is well known that white people may live for long periods of time in tropical countries where filariasis is quite common without apparently contracting the disease. This in contrast to other mos quito-borne diseases, such as malaria, yellow fever, and dengue, to which the white man is so susceptible. Francis, of United States Public Health Service, has presented a few concrete facts that pri marily explain how mosquito transmission is accomplished with much less degree of certainty and promptness in filariasis than in yellow fever and malaria. 1. The microfilaria does not multiply in the mosquito. 2. Only a small number of microfilariae are imbibed by the mos quito when sucking blood, and a still smaller number finally reach the proboscis. 3. Multiplication of the filarial parasite takes place in the lymph gland of man and must be deferred until a male and a female find lodgment within the same gland and there grow and develop their genital organs preparatory to bringing about a fecundated adult female parent worm, permanently located in that lymph gland. 4. Maximum opportunity of infecting mosquitoes with filarise is limited to a few hours around midnight. 5. The microfilaria is not injected by the mosquito into the blood stream of man, but deposited on the skin, which the larva must pene trate to find its way to the nearest lymph gland. 6. A comparatively small number of larvae find their way to the proboscis of the mosquito; a certain number pass into the hind gut and are lost; and of those that pierce the stomach wall and lodge in the thoracic muscles where the necessary larval changes must take place, only a small number finally find their way to the proboscis. 652 vol. xvii EDITORIAL. The life of an infected mosquito is probably shortened by reason of harboring the worms. From above facts it is readily seen that a large number of mos quito bites are necessary to bring about the favorable conditions needed for propagation of the worms in men with subsequent appear ance of microfilariae in the blood. Culex quinquefasciatus (syn. fatigans) has been proven to be the most successful vector of this disease. She is a night mosquito and hence bites at a time that is most favorable for infestation. This factor undoubtedly has some bearing on the epidemiology of the disease, in that the contact between the filaria-infested native popu lation and the white residents at this time is the least, the latter usually residing in separate sections of the city or colony. This is vitiated, however, to a certain degree by the fact that C. qttinque- faseiatus is a strong flier. With regard to the role of other mos quitoes as possible transmitters, both Steyomyia pseudosmtellaru and S. Scutellaria are proved vectors. Flu. of Batavia (Dutch East Indies), recently succeeded in infesting two anophelins, Myzomyia htdlotci and M. rossi Giles. A large number of larvae perished in these mosquitoes, however. Aedes col opus has never been proven an efficient host of Filaria bancrofti. Francis found that Microfilaria bancrofti taken into the mosquito's stomach did pierce the stomach wall in limited numbers and lodge in the thoracic muscles, but there they died as microfilaria? without development into the larval stage. In discussing the various accepted factors having bearing on the spread of filariasis. Flu points out that Batavia is a most suit able place for such a spread, but that some other factor or factors undoubtedly must be responsible for the rather small incidence of infestation in Batavia (from 2.3 to 15 per cent, according to the location of the. various districts) when compared with that of other countries where the incidence varies from 10 to 90 per cent. Flu believes that the relatively low figures obtained at Batavia are due to the transient character of the population. These transients serve as traps for the filaria, absorbing a large portion of the larva? from the infected mosquitoes, thus reducing the chances of infection among the settled population. Maxwell has recently published a rather exhaustive study of filariasis in China. In the infected areas of that country this dis ease plays a large part in diminishing the working capacity of a considerable number of the manual workers and in rendering many of theni altogether incapable of work. The geographical distribu tion of the disease in China is. according to Maxwell, rather sharply defined, forming a belt along the coast 15 to 25 miles broad, from the Yangtse River to the Tonquin border, with a tendency to extend up along the various river valleys. The infective index in this area No. 4. 653 EDITORIAL. is about 25 per cent. Most of the islands off the coast are infected, but not heavily. The author finds that the causative agent is nearly exclusively Filaria bancroftl. He gives a large array of clinical manifestations, which do not differ, however, to any marked extent, from those of other countries where such heavy infestation is present. Of particular interest is what Maxwell describes as filarial hemop tysis—hemorrhage from the lungs occurring in patients with filarial infection, correlated in time with an attack of filarial fever, with or without manifest evidence of lymphangitis. In some of the cases the author found the microfilariae in the expectorated blood; tuber culosis was excluded as far as was humanly possible. Another rare complication of filarial infection was gangrene of the scrotum. The author has seen eight such cases and finds that the condition is ushered in by a sharp attack of fever, accompanied by redness and swelling of the lower half of the scrotum. In a few days the lower half of the scrotum became black and comparatively dry, and if left to itself gradually sloughed off. (e. p.) CLINICAL NOTES. BRONCHIAL ASTHMA IN A CHILD APPARENTLY CURED BY INTRAMUS CULAR INJECTION OF PEPTONE SOLUTION. By R. H. Laninc, Lieutenant Commander, Medical Corps, United States Navy. There was noted in the Year Book of General Medicine, 1921, an abstract of an article by A. G. Auld, of London, England, relating to the curative results obtained in cases of bronchial asthma, par ticularly with children, by the injection of peptone solution. At the time, being interested in a case of severe bronchial asthma in a 9-year- old boy, I suggested to his mother that she allow me to give him this treatment, in as much as thorough tests performed by an emi nent Boston authority had failed to reveal any anaphlyactogen sen sitization which could have caused the condition. The abstract above mentioned is as follows : This article presents extended results of the treatment of asthma by the use of peptone, by A. C. Auld. of London, England. These results are based on a fairly large number of patients, all of whom received treatment for more than a year previous to the time this article was written. The method of Immunizing depends on the type of case ; no reaction appreciable to the patient should follow the injection (intravenous), and the latter should be made slowly. The treatment has been instructive in respect to the grouping of asthmatic cases. Two main groups occur, which show no tendency to pass into each other. One group comprises such patients as quickly respond to the treatment, and in whom the effect is more or less lasting, the recurrences being infrequent and milder in character. The other group is resistant, and is subdivisible into such patients as are totally resistant and those in whom by careful immu nization the disease may be largely overcome. , The first group presents, as a rule, most of the" following characteristics: General good health, little family predisposition, limited duration of the dis ease though a variable factor, regularity in the recurrence of attacks, freedom from bronchitis, and emphysema. Brief records of two patients in this group are cited. The first was a man 22 years old, who had suffered for four years. After seven injections the attacks began to yield, and ceased entirely after the tenth. The second patient was a woman 37 years old. She had suffered from asthma for four and a half years. After eleven injections she remained quite free for five months, when the disease returned in a milder form. Another short course of treatment was given, and during the next year she had only three slight attacks. The author states that no one responds better to the treatment than children. In them he makes the injection into the spinal muscles, basing the practice 655 656 Vol. XVII CLINICAL NOTES. on an observation by Meltzer, that the venous arrangements in these muscles are such as to cause the absorrtion of the medicament to approximate more to an intravenous injection. Witte's peptone must not be used, Auld says, as it may cause a severe local reaction. Most other varieties, however, are innocu ous in this respect. The same dose as that used intravenously for an adult should be given, but in double concentration. Bronchitis complicating asthma in a child is not the bar to treatment which it presents in an adult. None of the children hitherto treated has been refractory. In discussing Group 2 a few observations are given regarding cases which re sist the treatment. They include nearly all those individuals with chronic bronchitis and developed emphysema, and cases presenting any degree of cyanosis, even without bronchitis; also those in whom, apart from the asthmatic puroxyms, a more or loss oppressed condition of the respiration is practically never absent. As a rule, the affection has lasted many years, dating from childhood, or from the age of puberty, and a family history of asthma can nearly always be elicited ; sometimes hay fever is also found. Often the only effect that can be produced in such cases by means of peptone—and it has very important bearing — is the complete suppression of the attacks for a short period by a mildly toxic dose. For two or three weeks the patient for the first time experiences complete relief and thinks a cure has at last been at tained, only to be sadly disappointed. The dose of peptone necessary to affect this desensitization must be carefully considered in relation to the Individual case, and should produce, in from one to two hours, headache, malaise, shiver ing, slight rise of temperature, sickness, with pain in the abdomen and diar rhea. Sometimes a herpetic eruption occurs about the mouth or is even more widespread. In regard to Immunization in difficult cases, there are two. if not three, neces sary considerations presented : The first is the rate of injection of peptone and its dilution ; the second is the peptone to be used, and the indication afforded by the dermal reactions as the case proceeds. If the patient takes the peptone well, larger doses may succeed, given by very slow injection to avoid reaction. If the patient Is sensi tive to ]>eptone. however, great care is required, as the larger dose given in this way may precipitate an attack of asthma. Rarely this occurs very quickly — in a few minutes —with concomitant flushing of the face, especially if Witte's peptone is used, which seems to contain a toxic ingredient not present in muscle peptone. Again, a mixture of peptones sometimes succeed best. The dermal reaction (which may be prolonged by a Von Piquet borer) is not of much value at the beginning, as nonasthmatical subjects may give it, and it varies considerably in different persons, but as immunization proceeds it ought to lessen, and finally disappear ; that is. show no distinction from the control made with the solution in which the peptone is dissolved. Experience proves that the immunizing injection should never reach the critical point: it only injures the immunity mechanism. As a general rule, also, there ought to be three clear days between each injection. In the large number of cases of asthma treated by the author during the past three years the patient's diet hns been largely a negligible factor. The diet must, of course, be regulated, but the cutting out of certain articles rarely produces any marked or lasting effect. No doubt there are cases, but they form a small class, in which idiosyncrasy exists in respect to some par ticular food (which may be entirely carbohydrate). The same applies to asthmas caused by animal or vegetable emanations. Again, the dyspne'e No. 4. 657 CLINICAL NOTES. attacks in bronchitis may be due to the products of bacteria locally. But in the great majority of genuine asthmatics the explanation is rather to be sought in a defect in the hydrolysis, or metamorphosis of foreign protein resid ing in the digestive organs or in tile lymph or the body cells. To this protein poison the asthmatic individual is sensitive, and the bronchial muscles con tain the dominant receptors for it. This sensitiveness may be either heredi tary or acquired, and is influenced by climatic and other environmental con ditions. This leads one to consider the likelihood of other organs or tissues behaving in a similar manner, and causing recurrent fulminant disorders in which no local gross lesion is discoverable. The fact that in animal experi ments the protein poison or a foreign protein selects different organs in rela tion to the species may be of some significance in this connection. The family history of the boy is somewhat significant in that his father and paternal grandmother have been more or less constant sufferers from " catarrh," and in that one maternal aunt and one maternal uncle have been sufferers from asthma. Most of the deaths in the family appear to have been from pneumonia. Outside of chicken pox and influenza at the age of 5 years, the boy has been healthy, except for bronchial asthma and its attendant emphysema. The story of his asthma, according to bis mother, is as follows : When the child was 7 weeks old. he developed a condi tion diagnosed at the time as bronchitis, which diagnosis was later changed at the age of 4 months to bronchial asthma. The asth matic attacks appear to have had no relation to food or to the seasons and used to come on approximately every two months or so. The attacks might be mild or frightfully severe, lasting three or four days, and were typical in character. As time went on these attacks tended to become more and more severe and to occur at shorter and shorter intervals, until, finally, in the summer of 1921, they were recurring every 10 days or so, giving the child no chance to recuperate between attacks. At the age of (i years he had had his tonsils removed, and had been given a thorough physical exami nation, including laboratory and X-ray procedures and skin tests with numerous foreign proteins, both pollens and food, with no results, except that after the tonsillectomy there was a short period of freedom from the asthmatic attacks. The peptone treatment as described in the above abstract was started the latter part of August, 19*21, and prior to it a thorough physical, laboratory, and X-ray examination was given the boy with no abnormal findings except that he possessed a markedly emphy sematous chest, a mildly cyanotic appearance of the face, and was somewhat below normal weight. Nine injections of Fairehild's peptone were given three days apart into the muscles of the back in the following manner : £ c. c. 5 per cent peptone ; | c. c. 10 per rent peptone ; 1 c. c. 10 per cent peptone ; lf_ c. c. 10 per cent peptone : 2 c. c. 10 per cent peptone: 2£ c. c. 10 per cent peptone; 3 c. c. 10 per 658 Vol. XVII CLINICAL NOTES. cent peptone ; 3^ e. c. 10 per cent peptone ; 4 c. c. 10 per cent peptone. The peptone solution was made up fresh each time, autoclaved and filtered through cotton under aseptic conditions. After the first four or five injections, there was marked tenderness and pain at the site of injection, starting three or four hours after the injection and continuing for six or seven hours altogether, with slight fever and increase in the chest rales: the symptoms following the last three injections were very mild. Eight months have now elapsed since the treatment was given and to date there have been no signs of asth matic recurrence except for one attack 12 hours after the last in jection. The boy's mode of life and surroundings, as far as can be ascertained, have been the same since the treatment as before it. He has lost the mildly cyanotic hue which he used to possess, and has put on considerable weight. He still, however, displays the signs and symptoms of emphysema, but there has been a remarkable improve ment in his facial and physical appearance from that of a delicate child to that of a robust one. A CASE OF ABSCESS OF THE LUNG. By W. H. Funk, Lieutenant, Medical Corps, United States Navy. H. W. F., C. B. M., U. S. N., age 32, on the sixth day of his illness, was received at the Shanghai General Hospital. Shanghai, China, with a broncho-pneumonia, following a severe attack of influenza of two days' duration. Physical examination showed extensive in volvement of the right middle and lower lobes, and slight involve ment of the left lower lobe. Maximum temperature varied from 103° to 101° F. with an evening rise of 2£° to 3°. By the thirteenth day of the disease, the left lung had entirely cleared up, while the right lower showed patchy areas of consolidation. The patient be gan to have severe drenching sweats and septic temperature on the twentieth day. Needling of an area close to the spine showing in creased dullness, faint tubular breathing, and diminished transmis sion of voice sounds, resulted in a dry tap. The eough,which previous to this time had been loose with slight muco-purulent expectoration, had become paroxysmal in type and nonproductive. Eight days after there was a spontaneous expectoration of about 200 cubic centimeters of purulent foul-smelling fluid of a greenish tinge. Improvement, both subjectively and objectively, was very marked for a few days following. However, by the thirty-first day the temperature had again become septic, reaching 103° F. in the afternoon. During this time the lung signs were clearing up except for the area close to the spine which previously had been needled. Exploratory thoracentesis in this region again yielded a dry tap. No. 4. 659 CLINICAL NOTES. After four days of septic temperature there was another spontaneous expectoration of a large amount of purulent foul-smelling fluid. Relief was not so marked as that following the previous emptying. On the forty-second day there was the third and last spontaneous ex pectoration of 200 cubic centimeters of a sero-purulent foul-smelling fluid. Three days after, temperature dropped to normal and re mained so. A slight mucoid expectoration quickly disappeared. The patient made a very rapid convalesence and was discharged from the hospital to his home on the fifty-fourth day of his illness. Several X rays showed a uniform increase in density over the en tire right lung. Sputum examination was repeatedly negative for tuberculosis, with staphylococci, streptococci, and diplococci always in abundance. The white-blood count gradually rose, reaching its highest mark, 37,800, a few days before the second expectoration and fell to 8,000 four days after the last expectoration. The diagnosis of abscess of the lung was made on the spontaneous expectoration of large amounts of pus on three different occasions. In no case did this immediately follow a coughing spell. In the patient's own words, " It just started flowing out of my mouth." This second expectoration was brought about by the patient lying in bed, so as to give considerable gravity effect. Operation was con sidered, but deemed inadvisable after consultation because of the lack of exact localization. Open-air stimulative treatment was employed throughout the latter half of the illness. Therapeutic lying over the side of the bed gave no results. Although the patient had a markedly septic temperature, with frequent drenching sweats, he retained his strength in a surprising manner. Convalesence was rapid. Examination on discharge from the hospital showed slightly rough ened breathing and diminished transmission of breath and voice sounds over the right lower lung in back, close to the spine. UNUSUAL LOCATION OF AN EXTRAGENITAL CHANCRE. By W. T. Brown, Lieutenant, Medical Corps, United States Navy. While extragenital chancre is not an uncommon finding, the oc currence of one located on the eyelid is possibly infrequent enough to warrant a report of the case. H. M., private, United States Marine Corps, was admitted to the Shanghai General Hospital with a diagnosis of blepharitis of the right eye, which condition had existed for about six weeks and had gradually progressed in spite of careful treatment. Inspection revealed a slight erosion of both lids at the inner canthus, extending over the caruncle, with an area of swelling and redness of the surrounding skin about, the size of a dime. The 660 Vol. XVII CLINICAL NOTES. conjunctiva was slightly congested. The patient experienced no discomfort except from the troublesome epiphora which was present. The medical officer transferring the case suggested that the ulcer might be a chancre, and this diagnosis was confirmed by finding the Spirochaeta pallida in the scrapings from the ulcer. The day after admission a well-marked enlargement of the lymph nodes on the affected side, along the mandible and neck, was noted and a general ized macular rash appeared. The blood Wassermann was four plus. The primary lesion healed quickly during the subsequent treat ment, with no deformity remaining. BENIGN TUMORS OF THE MALE BREAST. By J. D. Benjamin and T. C. Quirk, Lieutenants, Medical Corps, United States Navy. Three cases of tumor of the male breast have appeared on this station during the past year. Two of these cases have been operated upon and the third is now under observation. A diagnosis of adeno-fibroma was made from specimens sent to the laboratory of the United States Naval Medical School in each case. J. V. D., aviation machinist's mate, was admitted to the sick list on June 1, 1921, with a tumor of the breast. This mass was com pletely excised under procaine. No reoccurrence of this mass lias been noted. D. H., aviation metalsmith, was admitted to the sick list on January 9, 1922, with a small mass in the breast. This mass was apparently completely excised under procaine on that date. On March 31, 1922. this man appeared at the dispensary with a re occurrence of the same mass. It was again excised, a mass the size of an orange being removed. Examination of this mass again revealed it to be fibro-adenoma. B. P. B., aviation carpenter's mate, was admitted to the sick list with a tumor of the breast on April 14, 1922, and is now under observation. These cases are reported because, although tumors of the male breast are not rare, it seems unusual for a tumor of the male breast when apparently entirely excised and reported as benign to reoccur twice as large in as short a period as three months and the second laboratory report to again show a benign tumor. The masses were not adherent but were hard, fibrous, nodular, nonvascular. There was no lymphatic involvement, no capsule, nor any retraction of nipple. They were superficial and freely movable- HOI No. 4. 661 CLINICAL NOTES. A DENTAL HINT. By Kmory A. Bryant, Lieutenant Commander, Dental Corps, United States Navy. It sometimes happens that a patient presents himself for treatment with a bridge in which the abutment tooth at one end has decayed inside the crown owing to disintegration of the cement, allowing the crown to become loose and the tooth structure to decay to such an extent that only the roots of the crowned tooth are left in the alveolar process. Usually these roots are in such bad condition that extrac tion is necessary. Such a condition leaves the bridge with only one abutment to assist in mastication. This soon becomes loose, owing to the loss of the sustaining structure of its accompanying abutment, and the denture becomes a menace to the health of the patient as well as a source of great pain and discomfort. This condition is usually found in lower bridges, and the usual abutment affected is the posterior one, due, as a rule, to inability to keep the abutment tooth dry while cementing the bridge in place. The cement soon washes out. and if the bridge is not at once removed, repaired, and recemented, the tooth structure dissolves, the bridge loosens, and soon becomes painful. The methods I have devised to meet this condition vary with the case in hand, but for illustration I will consider a bridge from the lower bicuspids extending back to the twelfth-year molar or the wisdom tooth inclusive, with the tooth structure dissolved, the roots only remaining under the abutment crown of the posterior abutment tooth. If the roots nre solid in their socket and have been filled to the apex, previous to original crowning, all that is necessary to do is to open through the cusp of the crown, cutting out nearly all of the gold cusp, to enable removal of all the softened structure down to u solid base on the remaining roots, insert in the root canals one or two of the screw posts of the smaller sizes and screw tight, take a piece of plate gutta-percha, soften and press down over the screw heads in such a manner that they project above the gutta-percha for at lea>t an eighth of an inch; then fill in the crown with amalgam, forming the cusp anew and carving to suit the case. When the filling is hard, finish up all projecting gutta-percha or amalgam at the gum margin, and the denture will again be as useful as the original struc ture. This case is one of the more ordinary kind remedied by a simple method. In some cases not only the structure of the abutment tooth is destroyed, but the roots are loose in their socket and usually abscessed. The procedure in this variety is the same as in the other until all the debris is removed. The next step is to extract the diseased roots from under the crown, taking them out laterally so as not to disturb the bridge from its original position. After 4539—22 8 662 Vol. XVII CLINICAL NOTES. the bleeding has been stopped, swab out the wound with phenol on cotton, followed by iodin used freely. Remove, by bur or curet, the septum of bone usually between the roots of a lower molar in such a manner as to leave a depression or socket at this point; again swab out as before and press down through the opening at the top of the crown cusp, a cone-shaped piece of gutta-percha, packing it as far down in the wound from which the roots have been extracted as it will go without bulging around the gingival margin of the crown and continuing to pack in gutta-percha until the crown is filled flush with the top and forming the cusp. Local application of a counterirritant around the gum margin is made and the patient is told to return in two or three days. When he returns, the inflammation has usually disappeared. The case is now ready for the permanent operation, which consists of replacing the gutta-percha cone with a reproduction of it made from a por celain tooth, cusp downward, into the depression and held in place by amalgam filling inserted around the part projecting up into the crown and forming the cusp. The placing as well as the formation of the porcelain base of the abutment is rarely the only difficult part of the operation, but it is not a complicated procedure. The case illustrated from X-ray radiographs before extraction of the roots and after insertion of the porcelain base is one of several cases which I have handled by this method. Figure 1 is a view of the bridge with the roots incased by the abutment crown as presented before extraction of the worthless roots and showing considerable loss of bone. Figure 2 presents the anterior abutment of the same bridge, which shows that but half of this root had any surrounding bone structure. Figure 3 shows the porcelain base in place two weeks after the extraction of the roots. Figure 4 pre sents the same view after the period of one month. Attention is in vited to the area of bone replacement shown in Figures 3 and 4. The patient informed me that after the first week he felt no in convenience whatever when using the bridge for mastication; in fact, he said it did service as well as the original bridge. SOME INTERESTING DENTAL CASES. By G. C. Fowler, Lieutenant, Dental Corps, United States Navy. Osteoma of superior maxilla. — Patient, male, aged 23 year. Ex amination revealed a large hard bony mass of tissue on the outer border of the alveolar process of the upper right maxilla. X ray showed this mass of tissue to extend from the first bicuspid pos terior to the mesial border of the third molar, and slightly below the normal gum margin to the attachment of the buccinator muscle, No. 4. 663 CLINICAL NOTES. protruding half an inch outward or laterally, and extending in ward toward the median line, practically filling the right antrum, and projecting into the nasal cavity- No enlargement of the hard palate was noticeable. The dark field illumination showed dense tissues on the right side. The left side was normal. There was slight retraction of the lip on the right side, which was very prominent on smiling. There was no pain to pressure. The hard tumor mass was rounded and immovable, and had never caused any discomfort. It was first noticed by the patient about two years ago, but being painless and not uncomfortable no attention was paid to it by him. The family history was negative to growths of any kind. The first molar was missing, and there was a loose, ill-fitting bridge on the second molar extending to the second bicuspid and pressing slightly, about one-eighth of an inch, into the gum. Both teeth were vital, with a slight thickening of the peridental mem brane at the apices. Conservative treatment was deemed advisable and operative pro cedures were postponed for the present. It was decided to wait until the tissues healed after the irritating bridge and teeth had been removed and to watch for future developments. The treatment consisted of removing the bridge and teeth involved, under local anesthesia, and taking an impression of the maxilla, including the tumor and surrounding tissues, as a control for future impressions. The tissues healed without difficulty. One month later another impression was taken and by careful measurement it was shown that the tumor had decreased in size. The patient was sent to duty and informed that he shoidd observe the growth and report when practi cal to have impressions taken, in order that careful observation might be made of the condition. Diseased teeth as possible cause of rheumatism; removal of un usual impacted molars. —Patient, male, age 28 years, suffering from rheumatism, was referred by ward doctor for possible focus of in fection. Eadiographs taken of all teeth showed several rarefied areas and the impaction of the upper molars. Under conductive anes thesia all teeth that showed rarefied areas were removed; also the impacted molars. The rheumatism cleared up so that the patient was able to do light duty in about three weeks after the teeth had been removed. Prior to removal of the teeth lie had been unable to move about without the aid of crutches for three months. Considerable space existed between the upper left second bicuspid and third molar. The first molar was lost when the patient was about 10 years old. He stated that he was about 17 years old before he erupted the third molar. The third molar extended buccally, giving considerable curve to the roots, forcing the lower molar to 664 Vol. XVII CLINICAL NOTES. strike on its lingual surface of the crown, causing considerable pain at times. Under conductive anesthesia the third molar was extracted, and on examination of the socket the crown of the second molar was dis covered, and it was also extracted through the opening made by the previous extraction. The socket was cleansed daily and in due time healed without difficulty. Strange to state, the impacted molar did not penetrate the antrum of Highmore. ADDITIONAL ASSURANCE FOR THE FIT OF A DAVIS CROWN. By 0. T. Lvnes, Lieutenant, Dental Corps, I nited States Navy. In the fitting of a Davis crown, it has appeared to me that to grind a crown and root so that they are perfectly adapted to one another is an impossibility. If you carefully observe the ground surfaces of both under a powerful glass I think that you will agree with me that it simply can't be done. There are several methods of overcoming this point, mainly by cast base construction, but even with this method the line of union between the crown and the root is not minutely perfect. That the following method is lasting is evidenced by the fact that the first Davis crown that I set by the use of this method is still intact after 10 years service. 1. Grind root and crown and fit post according to the usual method. 2. Cement the post into the crown. 3. Apply a bit of base-plate gutta percha, cut to the shape of the root, over the pin. (The hole for the pin to slip through can be readily made with the rubber dam punch.) 4. Heat the crown and post, with gutta-percha in place, over an alcohol lamp. Place the pin in the root and press to as near the proper position as possible. Remove the whole appliance from the root, trim the surplus srutta-pereha from the edges of the crown, reheat, and again apply to the root. Repeat this until the crown at tains its proper position and a perfect union is accomplished. Seal the edges of the gutta-percha to the crown. 5. Cement the finished product to place. This method not only produces a perfect union between crown and root, but it also establishes a base that acts as a cushion for the crown, thus prolonging the life of the root. The numberless cases of fractured teeth, where the line of frac ture extends above the alveolar process, can also be treated by this method, the gutta-percha being trimmed so that no irritating sur faces result. REPORTS. A REPORT ON THE NARCOTIC CONTROL ASSOCIATION OF CALIFORNIA. By W. G. Farwbli,, Lieutenant Commander, Medical Corps, United States Navy. The first State-wide narcotic conference in the United States was held on October 27, 1921, when the Narcotic Control Association of California was organized in San Francisco. More than 1.000 promi nent Californians interested in the control of drug addiction were present at this meeting, which was opened by Mayor Rolph ; addresses were made by doctors, lawyers, Federal, State and municipal of ficials, civic and religious workers—all of whom appeared to be impressed by the growing but insidious evil of drug addiction and the necessity for stamping it out. James A. Johnston, warden of San Quentin Prison, was elected president of the association, and the following resolutions were adopted : (1) The organization of a central State body and provisions for the formation of county organizations throughout California to work in conjunction with the State association. (2) Provision for the memorializing of the President of the United States, the National Congress, and the Department of State, whereby the provisions of the International Opium Congress at The Hague may be better enforced and the unlawful importation of crude opium and coca leaves be prevented, as well as the stoppage of the unlawful sale and distribution of narcotic drugs throughout the tforld. (3) Provision for the amendment of the Harrison Narcotic Act, whereby a minimum penalty of not less than six months' imprison ment nor less than a $500 fine shall be imposed upon first offenders, and whereby immediate deportation, upon completion of sentence, shall be made of all alien violators of the Harrison Act. (4) Provision for strict Federal suiveillance of all manufacture, sale, and distribution of narcotics. (5) Provision for more drastic legislation in California against the drug peddler. The writer was detailed as the naval representative at this con ference and gave a brief address upon drug addiction in the Navy, which may be summarized as follows : While there has been a general increase in drug addiction in recent years, the fact was brought 665 666 vol. xv :i REPORTS. out that this habit is not as prevalent in the service as in civil life because of the following conditions: (a) Recruits are given a thorough physical examination at re cruiting stations and later at training stations, which often elimi nates advanced cases of drug addiction. (b) The close associations and the military discipline required in the Navy tend to expose a drug addict sooner or later. (c) The fact that naval vessels move from port to port takes the addict away from his source of supply, and frequently results in HOHE-MADE HYPODERMIC JYRINGE LevtVier Comb Cii.sc- Cont-wner For 5yrino^ desertion, or occasionally in his coming to the medical officer, con fessing, and begging for a " shot." However, as drug addiction has unquestionably increased of recent years, particularly in large cities, and as the majority of recruits are obtained from this source, every effort is being made to discover and eradicate these characters from the Navy, where they have in creased proportionately of late. When drug addicts are found in the service they are promptly court-martialed and receive a "bad con duct" discharge. During the past year, of the ten thousand and odd men that passed through the naval training station at San Fran cisco only 11 drug addicts were found. These cases were dis charged and turned over to the police in San Francisco, who ini No. 4. 667 REPORTS. mediately freed them, as there were no civil charges against them. This is a situation that requires better cooperation between the civil and naval authorities, not only in San Francisco, but in other coast wise cities, as these addicts, when released from the Navy, con gregate in the large towns where narcotics are easily obtainable and swell the constantly increasing number of dope fiends in these com munities. If the police control of drug addicts was made more stringent, and suspected cases could be kept under surveillance until definitely diagnosed, when these cases appear at recruiting stations they could be turned over to the police, instead of being merely turned away from the recruiting stations to become foci for the further spread of this dread habit, as is the case at present. While it may appear at first glance to be a cruel and inhuman act to discharge drug addicts from the Army and Navy without trying to cure them, it must be remembered that the military service is in no sense a reformatory, and exists only for the military protection of the citizens of the country ; any condition that would lower the fight ing value of a military organization must be promptly eradicated. In order to show the extent to which drug habitues will go to get their " dope," the following incident was mentioned : A Navy enlisted man was recently arrested in San Francisco for some minor offense, not connected with drug addiction, and lodged in one of the city jails that contained a number of drug habitues. One of the " dopes " became friendly with the sailor and persuaded him to write to a certain address in the city requesting that a shirt be sent to him. In due course of time an ordinary woolen shirt arrived at the jail and, after being carefully examined by the warden, was delivered to the sailor, who unsuspectingly turned it over to the drug addict. Soon after, the jail authorities noticed that many of the prisoners were under the influence of a narcotic ; investigation showed that the shirt had been soaked in a saturated solution of cocaine, and after its arrival in the jail cut up in small pieces, distributed among the addicts and soaked in water to remove the cocaine, with the result that as one of them told the warden, " They didn't care how long they stayed in jail !" Another instance of the ingenuity shown in obtaining narcotics was the recent case of an enlisted man in the destroyer flotilla of the Pacific Fleet who was discovered receiving cocaine concealed be neath the stamps of letters addressed to him. The homemade hypodermic syringe shown in accompanying illus tration, which was found in the possession of a drug addict at the naval hospital, Great Lakes, 111., was then demonstrated to the mem bers of the association. NOTES AND COMMENTS. Headers of the Bulletin who have enjoyed the essays on subjects pertaining- to the history of medicine contributed to its pages by ('apt. J. S. Taylor, Medical Corps, United States Navy, will be pleased to learn that his essays on " Montaigne and Medicine," which appeared recently in serial form in the Annals of Medical History, have been issued in book form by Mr. Faul B. Hoeber, of New York. The book which bears the title " Montaigne and Medicine " con tains Montaigne's comments on the physic and physicians of his day; his thoughts on many material matters relating to life and death; an account of his bodily ailments and peculiarities and of his travels in search of health, all written in Doctor Taylor's charming style. It is dedicated to Dr. Hiram Itittenhouse Loux. of Philadelphia, " who ministers with consummate skill to forms of suffering for which there was no relief in Montaigne's day." During four trying years Doctor Taylor, as editor of the Bulletin, labored in the interest of the officers of the Medical Corps of the United States Navy, and we feel certain that each of them will wish him all success in his latest literary venture. One of the most enlightening papers on the chronic effects of suffocating gases which has come to our notice appeared in the May issue of the Journal of the Royal Army Medical Corps. Its author is Capt. Alexander Mearns. Royal Army Medical Corps. Lieut. G. H. Mankin, Medical Corps. United States Navy, has prepared the following abstract of this paper for readers of the Bulletin : Chronic effects of the inhalation of suffocating gases may be ex hibited for a variable length of time after convalescence in those who have been subjected to a so-called severe gassing in the field or else where, and also in those who, though never having undergone an acute gassing necessitating treatment, yet have been subjected to a slight intoxication or an absorption of noxious fumes more 6r less continuously for some time, as occurs among those working in in dustrial plants. The gases responsible for the effects studied by the author are those of tfie suffocative series—chlorine, phosgene, chlor- picrin, and trichlormethylchloroformate. 670 Vol. XVII NOTES AND COMMENTS. The cases were divided into two main classes— first, those with physical signs and symptoms indicative of organic changes, and, second, those in whom no such changes are found and are described as functional. As might be expected, the respiratory system shows the greatest degree of change. This change, in general, results in three types, each with its separate symptomatology and pathology. (a) Fibrotic type. —This condition is often seen as a sequel to an acute gassing, but much more frequently among workers in industrial plants with only a history of continual light absorption of gas, and seems chronic from the outset. Usually the onset has been insidious, and only after the symptoms become well established could the physi cal signs indicate the exact condition of the lungs, which was revealed as a fibrosis at the hilum of the lung, spreading along the bronchi and vessels. Symptoms.— Shortness of the breath on exertion is the first symp tom in cases unaccompanied by bronchial catarrh, while in others the symptoms resemble those of a chronic catarrh. The peri-bronchial fibrosis once having been established, the main symptom is a dry, unproductive cough, often paroxysmal, worse in the morning, the ex pectoration varying with the associated catarrh. Due to minute varicosities in the capillaries of the bronchial wall^ there is frequently blood-stained sputum, or even small hemorrhages. Shortness of breath, orthopnoea at night, faintness on exertion, general deteriora tion in health, loss of weight, and associated digestive disturbances are noted in greater or less degree. Occasionally cardiac symptoms, such as palpitation, retrosternal pain, and tachycardia occur, and are usually accompanied by sweating, irritability, and vague feelings of depression. There is an increased susceptibility to acute colds and influenza. Night sweats are uncommon. Physical signs. —The most constant sign is the shallow type of breathing, which becomes dyspneic on exertion. On percussion, areas of impaired resonance, often amounting to almost absolute dullness, are found over the hilum of the lung, particularly on the right side. These areas vary with the extent of the fibrosis and spread in the direction of the bronchial tubes. Vocal fremitus and resonance are increased over these areas, and the type of breathinsr is bronch- vesicular, with slightly prolonged expiration. There is im paired ventilation, loss of elasticity of the chest wall, and a restric tion of the movements of the diaphragm. The restriction of the movement of the diaphragm is not functional, but probably defensive, as the taking of a deep breath gives rise to pain and cough. X-ray examination shows areas of shadow which correspond to the thick ened areas revealed clinically. These thickened areas spread out No. 4. 671 NOTES AND COMMENTS. from the hilum into the lung like a fan and coincide with the distri bution of the bronchi, bronchioles, and blood vessels. As far as could be learned the previous history of the cases recently examined contained nothing which would obviously predispose to lung disease. With regard to the changes that actually occur, there is a pro gressive peri-bronchial fibrosis extending from the hilum of the lung outward, in advanced cases, to the ultimate distribution of the bron chioles, with or without associated bronchitis and emphysema. There is also a loss of elasticity in the whole of the respiratory tract, due to a loss or destruction of the elastic fibers throughout the lung. Evidence of anoxemia in several of the recent cases has been proven by the beneficial effects of a sojourn in the high oxygen chamber, though the effects soon passed off, and also by the effort syndrome . symptoms frequently associated, which have been shown to be largely due to oxygen want. Considering the large number of workers who do not develop this condition, it is evident that the inhalation of the gases is only one element in the production of fibrosis, that individual susceptibility must function in its occurrence and a low- grade bacterial infection institute or continue its development. (&) Emphysematous type. —The existence of emphysema after gassing in cases with no history of previous lung disease is usually associated with or is a sequel to the other two types —fibrotic and bronchitic. The respiratory and cardiac symptoms, the physical signs in the lungs and heart, in no way differ from those observed in cases of emphysema from other causes, except in the rapidity of onset. (c) Bronchitic type. —Most of the cases of supposed tuberculosis following gas inhalation are of this group. The symptoms and signs are so suggestive of tuberculosis that diagnosis can only be made after careful examination. Symptoms. —These are, in the main, similar to those of bron chitis—cough, expectoration with or without hemorrhages, marked loss of weight, transient fever, shortness of breath, and general de terioration of health. Examination of the chest reveals bronchitis rales generalized or localized to certain areas, harsh vesicular breath ing, and impaired resonance on percussion. Physiological examina tion in these cases shows a permanent lowering of the respiratory exchange and consequent deficiency in respiratory functions. The symptoms described resemble so closely those occurring in chronic and subacute tuberculosis of the lung that the relation of gas poison ing to this disease has been considered, especially in view of the apprehension originally entertained. Several thousands of gas cases have been examined for the frequency of tuberculosis by many clinicians, whose reports are of especial interest. The conclusion 672 Vol. XYlt NOTES AND COMMENTS. that presents itself after the study of these papers is that the in halation of gas has an extremely small influence on the occurrence of tuberculosis, but that in a few cases it may light up a focus of infection previously latent. The other possibility, namely, whether acute gas poisoning creates a condition in the lung predisposing or favorable to the development of tubercle, finds a tentative answer, at least, in the work of Achard upon guinea pigs. Among the cases recently examined no tuber cular disease was discovered. Digestive system. —Digestive troubles traceable directly to the action of gas are extremely few, though various symptoms indicative of atonic dyspepsia are to be observed upon occasion, but these gradually disappear after a period of a few months. Where they do persist, two factors in their causation are evident, the general weakness and malnutrition consequent on want of oxygen and, prob ably more important, the absence of the massaging effect of the diaphragm due to its restricted movement. Cardiac system. —No organic lesions have ever been traced directly to gas poisoning, though changes in the heart, hypertrophy, and dilatation naturally follow on the lesions of the respiratory tract described. Sequellce xrith no organic lesions. —Especially among the " lightly gassed " we find a group of cases wherein little can be noted clinically to account for the symptoms. The anoxemia and symptoms that are present, and which may last for a considerable length of time, yield to the treatment of a sojourn in the high oxygen chamber, thus show ing that they are not due to any gross physical change, but constitute a definite gas neurosis. The severity depends upon the " instability " of the individual, and is probably largely preventable. The use of oxygen is considered to be the proper form of treatment for this type of cases. In conclusion the author states that " it has been shown that there are two types of sequellse to inhalation of asphyxiation gases, (a) A type affecting primarily the respiratory system with definite progressive organic changes of the nature of a peribronchial fibrosis, emphysema, and pseudotuberculosis, (b) A type of gas neurosis, having the signs and symptoms allied to those of effort syndrome, without demonstrable organic changes." Recently a letter was received by the Bureau of Medicine and Surgery from a medical officer who desired to know if the bureau wished a strict compliance with article 1139 of the United States Naval Regulations which states that " the medical officer shall not give an unofficial certificate of ill health or of inability to perform any duty." No. 4. 673 NOTES AND COMMENTS. It appears that this officer, who is on duty at the dispensary of a large navy yard, frequently receives requests for certificates of disability from injured yard employees in order that they might receive compensation from various lodges, benevolent societies, and relief associations, and that the refusal of these certificates, in ac cordance with the regulations, at times, submitted an injured work man to an injustice, inasmuch as his medical attendant was pro hibited from giving him the certificate necessary in adjusting his claim for compensation. The bureau forwarded the correspondence to the Judge Advocate General for a decision as to whether article 1139, United States Naval Regulations. 1920. applies to employees of a navy yard. The decision of the Judge Advocate General may be gleaned from the following extract of a letter from the .Judge Advocate of the Navy to the Chief of the Bureau of Medicine and Surgery: "Article 1139 of the United States Navy Regulations, 1920, pro hibits medical officers from giving unofficial certificates of ill health or of inability to perform any duty. It is the opinion of this office, however, that this article of the regulations merely defines the rela tion of a naval medical officer to other individuals in the naval serv ice and does not apply to the relation of a naval medical officer to civilians employed in navy yards or naval stations under the juris diction of the Navy Department. "This office is. therefore, of the opinion that requests for certifi cates from, the civilian employees of navy yards or station* to enable them to receive compensations from lodges, benevolent societies, and the yard relief association may be properly unofficially granted." The impression is quite general that the white race, does not thrive in the Tropics. Not long ago an article appeared in a London paper advocating restricted admission of the colored races to tropical Australia on the ground that whites can not live and labor in the Tropics. About the time it was published an article appeared in the Medical Journal of Australia describing what has happened to whites who have re sided for several generations in the Dutch East Indies. It is not generally known, says the Living Aye, that families of Teutonic blood have been actually living for five or six generations in Hol land's tropical possessions. Some of these have retained their white blood pure: others have mingled with the natives. The author of the article. Doctor Elkington, of the Common wealth Health Department, describes the history of nine families of Dutch ancestry sprung from settlers who took up their abode upon the island of Kisar in 1767. After the Dutch garrison withdrew 674 Vol. XVII NOTES AND COMMENTS. from the island, these families remained behind, intermarrying with the natives, relapsing into heathenism, and losing all memory of the Dutch language. During the eighties the Government became aware of the existence of these people and tried to help them, with the result that they have been rechristianized and won back to civilization. Doctor Elkington reaches the conclusion, by studying these white or part white denizens of the Tropics, that they have maintained their mental and physical traits substantially unchanged after five or six generations. These characteristics have survived in spite of environmental conditions and associations lasting over 60 years, from 1819 onward, and probably for some 70 years or more, which are generally sup posed to be totally unsuitable for persons of European stock. These conditions have included native standards of food and food supply, endemic malaria, the psychological effect of what must have been for the earlier generations an acute sense of abandonment by their own race, life under the rule of native chiefs, constant association with a native race of low mentality, loss of European language and European religion, interbreeding to a high degree, and constant exposure to a tropical climate. There is nothing in the available history of these people to show that a tropical climate per se has tended to produce degenerative effects on them or to limit fertility. Whatever evidence they may have shown of lowered physical or mental activity in the past can be fully explained by the environ mental conditions of food supply, malaria, and particularly of native associations, aided possibly by the accentuation of stock weak nesses arising from interbreeding over several generations. It is always a source of pleasure to note the success of medical officers with whose work we are familiar, even though they serve under another flag. In the British Medical Journal for May 27, 1922, we read that the gold medal founded by the late Sir Gilbert Blane has been awarded by the Director-General of the Medical Department of the Navy and the presidents of the Royal College of Physicians and the Royal College of Surgeons to Surgeon-Com mander Sidney W. Grimwade, Mho obtained a first-class certificate at the examination held in February, 1922, for promotion to the rank of surgeon-commander. Three Blane medals which remained un- adjudged owing to the absence of promotion examinations during the war have been awarded to Surgeon-Comander Reginald St. G. S. Bond, Surgeon-Commander Robert W. B. Hall, and Surgeon- Commander Sheldon F. Dudley, for distinguished professional zeal and ability displayed throughout their service career. No. 4. 675 NOTES AND COMMENTS. Readers of the abstracts which have appeared in the Bulletin in late years will recall the researches of these men in their respec tive specialties. From the Lancet for May 27, 1922, we learn that out of some 360 titles of rare works on old medicine, advertised for sale by the International Antiquariaat of Amsterdam, more than 50 relate to the use and abuse of tobacco. This large proportion of books de scriptive of a particular kind of intoxication might lead us to infer that old Dutch medicine was chiefly concerned with the evils of smoking, but the works in question are rarely Dutch and mostly modern, and, as a matter of fact, smoking has had from the earliest times a bad name. The priests or councils of the American Indian tribes seem to have been the first known smokers, and probably used tobacco as an intoxicant. They inhaled smoke by way of the mouth or nostrils when treating of war—the " pipe of peace " it was called euphemistically—or when proceeding to utter prophecy. When introduced into Europe, smoking was still held by many to have a mystic significance, and it became necessary for Pope Urban VIII to excommunicate certain priests who took tobacco while officiating at the mass. This was in 1624, some 20 years after James I had for bidden the use of tobacco in his realms. A curious work, No. 241 in the catalogue, is the Commentary of Paullus, " De Abusu Tabaci Americanorum ipsissima est Chamae- leaguos Dodonaei." This very rare book was published at Stras bourg in 1665. Other interesting works are : Tobacco, injurious to the Constitution and its Use Scripturally Wrong. Dialogues be tween a Doctor and a Miner, by a Surgeon, London, 1840 ; Murray on Snuff-taking : Its Utility in Preventing Bronchitis, Consump tion, etc., 1870; Lowy on Raucherparanoia ; Jamet on L'Art de Fumer, Metz, 1845; Heward's St. Nicotine, 1909; and Bragge's Bibliotheca Nicotiana, Birmingham, 1880. The last-mentioned work is the bibliography of tobacco, and is to that subject what Lowndes and Brunet are to literature in general. Among rare works offered for sale in this catalogue, but not necessarily dealing with nicotine and tobacco, special mention should be made of the Isagoge-Magico-Medica, of Aug. Etzler, published at Argentoratum (Strasbourg) in 1631. This deals with the whole subject of signaturism. Bidloo's superb volume with wide margins known as Ontleding (Anatomy) des menschelijken Lichaams, is here offered for 75 florins. The plates illustrative of human anat omy, by the celebrated artist G. de Lairesse, are those which Cowper embodied without acknowledgment in his famous " Myotomia." His theft was not suspected till the discover}7, by an assistant librarian in the Royal College of Surgeons in England, that the name of Bidloo 676 Vol. XVII NOTES AND COMMENTS. had been covered with a neat circular label on Cowper's title-page, the same process having been gone through in other similar volumes. One is sorry to take away the reputation for literary honesty of so good a surgeon as Cowper, whom, indeed, Lowndes defends in a note. Here also is offered for 65 florins Gautier Dagoty's extremely fine atlas of the Anatomy of the Generative Parts of Man and Woman. The book is one of great rarity, and is especially interesting in that the plates, which closely follow nature, are perhaps the earliest known instances of color-printing in three colors, an inven tion usually considered to be of quite recent date. Gautier Dagoty published his great folio in Paris as long ago as 1773. J. R. Kuth, writing in the Journal of Bone awl Joint Surgery for April, 1922, informs his readers that from a study of 208 cases of lower back pain, any injury or disease affecting the lower back structures (muscular, ligamentous, bursal, osseous, or joint) may give rise to a similar symptom complex in cases of chronic low back pains. Unfavorable static conditions in the lower back or ex tremities resulting from abnormalities in the lower extremities, postural or occupational strains, or from fatigue or weakness, fre quently exist in these cases and operate as a cause in the production of symptoms either alone or in conjunction with other causes. In all cases of low back pain, the possibility of a progressive disease of the spine or of the spinal cord should be kept in mind. The best results from treatment were obtained in cases in which static abnor malities were corrected, in which lower back structures were pro tected or put at rest, and in which such structures, if shortened, were stretched. Graduated systematic exercises are an important ad junct in the treatment of many of these cases. The so-called concentration method for tubercle bacilli in expecto ration in cases where they are present in scanty numbers has been for some time past- effected by forming an emulsion with antiformin, which dissolves the cellular and mucous elements and allows the bacilli to fall to the bottom of the liquid. By this method, however, many bacilli of recent development may be dissolved entirely, and others damaged to such an extent as to lose their special staining peculiarities. The concentration, therefore, consists merely in the collecting at the bottom of the liquid of those bacilli which have survived the process with a respective diminution in their total number. Tuberculous sputum to which the process of so-called con centration may be most usefully applied is that from patients in the early stages of the disease in which the bacilli are scanty, and there- No. 4. 677 NOTES AND COMMENTS. fore difficult to demonstrate with the ordinary methods of staining. From a negative result the patient feels himself justified in neglect ing any kind of precaution, and in such a case it is indispensable that a result should be arrived at which is as near as possible abso lutely true. The Lancet for May 27, 1922, calls attention to the fact that Prof. N. Pane, of the Bacteriological Institute at the University of Xaples, has just published a new method in which a concentration of existing bacilli is obtained without any diminution in their num ber. The suspected sputum is placed in a sterile glass receptacle and four times its volume of physiological salt solution added; this is then incubated at 37° C. for 24 hours. During this time the mucus and cells are liquefied by the proteolytic enzymes produced by the accessory microorganisms which are more or less abundant in all sputum. The centrifugalization of the bacteria is by this means rendered easy by the elimination from the liquid of the organic sub stances which spoil the clearness of the preparations, and the tubercle bacilli are readily shown by the Ziehl-Neelsen method. In some cases investigation by this method has shown only occasional groups of agglutinated tubercle bacilli. Professor Pane considers this to indi cate a slight immunizing defense in the organism. 4639—22 9 NURSE CORPS. REPORT OF THE COMMITTEE ON NURSING PROBLEMS FINANCED BY THE ROCKEFELLER FOUNDATION. The conference of persons interested in the development of nurs ing, which met in New York at the invitation of the Rockefeller Foundation in March, 1919, has submitted a report after practically two years of investigation. The original committee was invited to consider the development of public health nursing, and was made up of well-known members of the medical and nursing professions and several lay members whose work has been along the lines of in dustrial hygiene and public welfare. The completed committee placed the actual conduct of the investigation in the hands of Miss Josephine Goldmark, whose work in social research and studies on industrial hygiene fitted her for such a task. The committee has made special mention of its appreciation of her study of the difficult and complex problems and believes that the detailed report will prove of funda mental value in the development of nursing and of nursing educa tion in the future. In February, 1920, a second conference was called, also at the invitation of the Rockefeller Foundation, and at this conference the discussion centered on the proper training of nurses within hos pitals and on private duty ; in fact, the entire trend of nursing educa tion was considered. The result of this conference was the widen ing of scope of the former committee, which was increased in June, 1920, by six members, including superintendents of hospitals and of nursing schools, a clinician, and a representative of mental hygiene. A brief resume of the report and the conclusions of the committee will be of interest to our readers. In an endeavor to secure disinterested and impartial opinions on controversial subjects, both nurse and lay investigators were em ployed in the field work. The study of hospital training schools was carried on by Miss Elizabeth G. Burgess, R. N., inspector of training schools of the New York State Department of Education; Mrs. J. B. Piggott, R. N., Maryland State inspector of training schools; Miss Carolyn E. Gray, head of the department of nursing education. Western Reserve University ; Miss A. H. Turner, pro fessor of physiology. Mount Holyoke College; Miss F. G. Gates. 679 680 NURSE CORPS. Vol. XVII formerly dean of the Women's College, University of the State of Illinois. Miss Turner also made a study of postgraduate courses for teachers and administrators in schools of nursing. In compiling data for the chapter on hospital training schools, assistance was rendered by Miss Edith R. Hall, Mrs. M. P. GatTney, and Miss P. K. Angell. For the study of public health agencies, the field work was carried on by Miss Grace R. Bolen, Miss Christina C. Miller, Miss Elsa M. Butler, who were not nurses but experienced in public health work, and Miss Helen Ross, experienced in industrial investigation; Mrs. B. A. Haasis, R. N., and Miss Janet R. Geister, R. N., secretaries of the National Organization for Public Health Nursing, and Mrs. A. M. Staebler, R. N., secretary of the Massachusetts Committee on Health in Industry. In the study of private duty nursing the field work was carried on by Mrs. J. David Thompson and Miss Adda Eldridge, R. N., with the special assistance of Miss Sara E. Parsons, R. N. The first part of the report considers the role of the nurse in public- health work, and gives an outline of the major health problems of the present day, such as the control of infant mortality and tuberculosis. It is stated that education is the only means of accomplishing the changes in daily habits of people which alone can solve these prob lems. The objection of the health administrator may be approached to a limited extent by mass methods, but direct personal contact with the conditions of the individual life is essential to success in a matter so trmy personal as hygiene. After enlarging upon this fact, the committee stated that all public health authorities appear to agree that the need for nurses is the largest outstanding problem before the health administrator of the present day. This need has led the authorities to consider the possibility of finding a short way out of the difficulty by the employment of women who have been given a course in public-health work less involved than that required for the education of a registered nurse. The problem of the necessary and desirable equipment of these teachers of hygiene was carefully studied, and the various types of public-health nursing were noted and investigated. The hotly debated question whether the public- health nurse should or should not render bedside care was reviewed. The function of other messengers in the field of public health were noted and their work was pronounced correlated to that of the health instructor which, combined with bedside care, is a function possible only to the fully trained nurse. The committee is convinced that the teacher of hygiene in the home should possess, in the first place, the fundamental education of the nurse and that this should be sup- Mo. 4. 681 NURSE CORPS. plemented by a graduate course in the special problems of public health. The conclusions of section 1 are as follows : That, since constructive health work and health teaching , in families is best dime by persons capable of giving^ general health instruction, as distinguished from instruction in any one specialty, and capable of rendering bedside care at need, those agents re sponsible for such constructive health work and health teaching in families should have completed the nurses'1 training. There will, of coxtrse, be need for the employment, in addition to the public-health nurse, of other types of experts such as nutrition workers, social workers, occupational therapists, and tlie like. That as soon as may be practicable all agencies, public or private, employing public-health nurses should require as a prerequisite for employment the basic hospital training, followed by a post- graduate course, including both class work and field work, in public- health nursing. The committee next investigated the modern hospital and the mod ern dispensary, which represents social forces of enormous and growing possibilities. The need for women of fundamental train ing and high qualifications is as manifest here as in the field of public-health nursing; in fact it may be regarded as of first im portance in this field of work. Defective preparation and a lack of proper qualifications in many instructors in schools of nursing were noted. The appointment of full-time instructors is a recent devel opment in schools and is not yet general ; but it is a marked advance as the results noted shows. The committee is of the opinion: That the career open to young women- of high capacity, in public- health nursing or in hospital supervision and nursing education, is one of the most attractive fields now open, in its promise of profes sional success and of rewarding public service; and that every effort should be made to attract such women into this field. The next problem considered by the committee was the funda mental one of providing nursing care for the sick of the community. The shortage of nurses which had existed during the war has been overcome to an appreciable extent during the last three years, the census reports showing an increase of 83 per cent; 149,128 is the num ber of trained registered nurses reported in 1920. Of these, 11,000 are employed as public-health nurses and the same number in hos pitals and other institutions. The remaining 120,000 available for private-duty nursing are not all in active practice. In the cities the supply of trained nurses appears to be adequate, and the failure to receive nursing care is to be sought in economic factors rather than in shortage of nurses. 682 Vo'. XV i I NURSE CORPS. Discussion of the subject of the quality of the nursing service brought out radical differences of opinion. Some private physician consider the graduate " overtrained " and believe a woman with a very brief training in bedside routine would be as satisfactory. As a result of this feeling, there have been persistent efforts to break down the standards of nursing education which have been laboriously built up during the past years. Others believe that the removal of the safeguards which guarantee the quality of service necessary for safety constitutes a real danger to the cause of public health. The committee records its conviction as follows : That for the care of persons suffering from, serious and acute dis ease the safety of the patient and, the responsibility of the medical and nursing professions demand the maintenance of the standards of ('durational attainment now generally accepted by the best sentiment of both professions and embodied in the legislation of the more pro gressive States; and that any attempt to lower the standards would be fraught with real danger to the public. The committee found that many physicians demand nurses of a higher type than those who are now in the field. While others desire merely " hands for the physician." with a minimum of educa tion. Eeviewing the facts, it seemed that high natural qualifications and sound education are needed for the care of acute and serious illness and for public health work: but for the care of mild and chronic illness and for convalescence, a different type of capacity and training could be utilized. The distinction, the committee believed, should be according to the type of illness involved and not based on economic grounds. The survey does not indicate that the income of the private duty nurse is especially large. The solution of the economic problem which confronts the family of low income must be sought along lines of cost distribution through community organization, or along lines of group insurance. The problem of subsidiary nursing is not new. In 1920 the num ber of nurses, male and female, in the United States was 300.0(H). and of these more than half were below the standard required of the graduate nurse. There are grave dangers in the existence of a loosely defined, unregulated group of partially trained workers, and serious complications arise when this group functions in the same field with a more highly educated type of workers. A funda mental duty to the public has been discharged by the nursing pro fession in stimulating the development of laws which define the practices of the profession and protect the community against fraud. The lower grades of nursing should also be defined and registered. The committee recognized the difficulty of selecting a proper name No. 4. 683 NURSE CORPS. for this subsidiary group, but believe that " nursing aid" or "nurs ing attendant " best meets the need for clear differentiation while providing a suitable name. That committee recommended : That steps should be taken through State legislation for the defi nition and licensure of a subsidiary grade of nursing service, the subsidiary type of worker to serve under practising physicians in the care of mild and chronic illness, and convalescence, and possibly to assist under the direction of the trained nurse in certain phases of hospital and visiting nursing. (To be continued.) THE PAST PLAYED BY A NURSE IN A HOSPITAL PROGRAM.1 By Miss Ldcy Minnbobrode, Superintendent of Nurses, United States Public Health Service. Ordinarily, well regulated hospitals may be divided into three distinct departments —medical, nursing, administrative. These de partments are coordinated under the superintendent of the hospital, preferably a physician with executive ability, able to understand and appreciate the psychology of the heads of his services, to coordinate the work of all units and branches of units in order to make a perfect whole. We will take it for granted that we are dealing with a hospital in which the ideal service to the patient and the welfare of the patient are of paramount interest. Next to the medical service in importance must be placed the nurs ing service, and if the medical service is to be effective the physicians should be able to place implicit confidence in the efficiency and loy alty of the nursing service. The superintendent of nurses and directress of the training school, if there is a training school in connection with the hospital, must be in sympathy with the hospital administration, loyal to the superin tendent of the hospital, to the medical staff, and to the ideals estab lished by the nursing profession. She should be in charge of all personnel whose duties are concerned with the care of the sick, under the superintendent of the hospital. All matters relating to this class of personnel should be conducted through her, and in all questions of policy affecting her people she should have a voice and a vote. In disciplinary matters she should be sustained unless there is reason to doubt her justice, in which case she should be removed. The practice of exploitation of the student nurse for the benefit of the hospital is as old as nursing, and has resulted finally in bringing 1Read before the Catholic Conference in Washington, D. C. 684 Vol. XVII NURSE CORPS. about a situation which has placed many hospitals in a difficult position at the present time, since there has been a pronounced de crease in the student applicants for nurse training at a time when there is a very pronounced demand for a greater number of qualified nurses. The ratio of student nurse to hospital beds should be 1 to 5, in order that proper time may be allowed for study and rec reation, and for every 6 students in a hospital there should be 1 graduate. This schedule may be modified to some extent by the construction and equipment of the hospital and may have to be increased for the same reasons. The practice prevalent in many hospitals of keeping student nurses on special duty with private patients for which the hospital is paid should be abandoned. Six weeks of special duty is sufficient for any student nurse, and the constant placing of student nurses on special duty for the purpose of earning money for the hospitals is but another form of ex ploitation of the student nurse for the benefit of the hospital to the detriment of the student. A happy and contented nursing personnel makes for a happy and contented patient, since the nurse is in more constant contact with the patient than any other hospital personnel. The patient, too, is dependent upon the nurse for care and comfort, and the attitude of the nurse toward the hospital and its administrators will be in evitably reflected in the patient. Therefore, as a matter of policy, if not of justice, the nurse should be considered as an integral, im portant element in the success of the hospital. It is worth while to make her contented and happy in her work and loyal to the hospital by providing proper living conditions and quarters, adequate time for both recreation and study and ample educational opportunities and advantages, and to acquire a realization that to the student nurse as well as to the interne and medical student, the hospital is her workshop, study, and laboratory. How can the hospital authorities reconcile a proper recognition of their responsibilities to the nursing service with the necessity, pres ent in most hospitals, for rigid economy in order to meet necessary expenses ? First. —It is essential that the nurses receive a proper education. This is as much a matter of vital interest to the medical staff as to the nurse herself, and nothing should be allowed to interfere with the course of instruction as established by the hospital and approved by the State board of registration for nurses. Second. —Proper quarters and recreational facilities should be provided, with adequate supervision of play as well as of work. Third.—Nurses may be of greater service to the hospital and increase their value to the public as well by receiving instruction in the various therapies which have now become an integral part of \0. *. 685 NURSE CORPS. all our first-class hospitals. In all branches of physio-therapy nurses can be used. The advantage of this is obvious, since because of the nurse's medical knowledge she can be made more valuable. The elimi nation of many different classes of personnel means the elimination of friction. There is no desire to infringe upon the rights and privi leges of the physio-therapists in making this suggestion, but it is understood that in the United States Navy this practice has been followed with great success. Fourth.—In occupational therapy and social service also, nurses should receive some training, and the heads of these various depart ments who would be experts in their specialty should be considered as a part of the teaching staff for student nurses. Fifth.—The same is true of the dietetic department. The chief dietition is also a part of the teaching staff, and nurses should be of use to her in her department and should receive a thorough grounding in dietetics, at least to the extent that they would be able to follow intelligently instructions in the preparation of diabetic and salt- free or other special dietaries. The fundamental essential, if successful administration is to be obtained, is cooperation among the heads of the various departments and with the administrative head of the hospital who coordinates the interests and activities of all these units. Through a close co operation, unnecessary expense can be avoided, greater care given to the preservation of equipment, and to the elimination of waste, and the strict economy necessary in order to make ends meet financially can be more surely established than by a reduction in the essential comforts for the personnel. A loyal and efficient nurse body will be interested in making the program of the hospital a success. Therefore, let us remember that only through the close cooperation of the various services can the true mission of the hospital be fulfilled, and that mission is the adequate, efficient, and interested care of patients. At the recent convention held in Seattle, it was recommended, voted upon, and carried that the superintendents of the Federal nurs ing services be members of the advisory council of the American Nurses Association. DIGEST OF DECISIONS. The Comptroller General has decided that the stoppage of the pay of an officer absent without leave or because of misconduct includes the stoppage of his rental and subsistence allowance. He has further decided that an officer not having dependents, or an officer traveling with his dependents on a commercial steamer or transport at Gov ernment expense, is not entitled to a rental allowance. The following correspondence is of interest in relation to the ques tion of origin not in the line of duty : Department of the Navy, offrce of the .tvdoe advocate general, Washington, July 22, 1922.

Forwarded: all papers returned. 2. It appears from the matter contained in attached papers that the above- named man first enlisted in the United States Navy May 29. 1915. and served until November 14. 1916. upon which date lie was discharged. It further ap pears that he reenlisted in the service January 8. 1918, and served until on or about June 19. 1918, on which date he was discharged by medical survey on account of "constitutional psychopathic state." origin not in the line of duty, not due to his own misconduct. 3. From an examination of the matter presented in attached papers this office is of the opinion that if there existed any disability which warranted the discharge of this man from the naval service by virtue of a medical survey, said disability must be held to have originated in the line of duty. The fore- Koing conclusion is based upon the case of Vincent Badolato, ship's cook, second class. United States Navy, May 19, 1921 (File No. 7657-390:40), who was discltarged from the naval service on account of " dementia prtecox," not in the line of duty, due to a " predisposition existing prior to enlistment." In that case it was held that the naval service was estopped from asserting that Badolato was suffering from a predisposition toward dementia prwcox before entering the service owing to the fact that he had served through a duration of the war enlistment, received a discharge, and subsequently re- enlisted, no evidence of said condition having been found prior to his enlistment. 4. The case of Vincent Badolato, above referred to, has been consistently followed by this department in all similar cases since its approval. For ex ample, it was held in the case of Rodney G. Clark, apprentice seaman, United States Navy, approved September 13, 1921 (File No. 29372-3) that before a 687 688 Vol. XVII DIGEST OF DECISIONS. finding of " not in line of duty " based upon a presumption that the disability complained of existed prior to the claimant's enlistment in the naval service is warranted, it must be shown by definite facts that said individual was actually suffering from the said disability prior to his enlistment. In other words, quoting decision, " The facts which must be shown in a case such as the one under consideration before a finding of ' not in line of duty ' is war ranted, in the absence of fraud, are facts established by proof of their exist ence prior to enlistment; for example, if it is shown from the records of a creditable institution or the testimony of a reputable physician attending the complainant prior to his enlistment that he was suffering from tuber culosis, chronic, pulmonary, at that time ; or if a statement of the claimant describing certain physical conditions which he had noticed prior to his en listment is submitted, and this statement" could have no other plausible explana tion than that he was suffering from tuberculosis in some form at that time, i. e., prior to his enlistment, a finding of ' not in the line of duty ' would be warranted, but under no other condition except where fraud is shown." 5. Likewise in the case of Hansel Arcebole, approved October 4, 1921 (File No. 29372-2), it was held that in view of the facts that there was no evi dence of epileptic seizures prior to his enlistment in the Marine Corps since early childhood, the disability complained of must be held to have been in curred in the line of duty for the reason that a history of epileptic seizures during early childhood is not deemed sufficient to warrant a holding of " not in the line of duty," in the absence of facts showing that the claimant had suffered such seizures within a reasonable time prior to his receiving a blow on the head of sufficient force to knock him down, which blow was received while in the naval service arid may in fact have brought on these seizures. 6. In the case of Walter Reinold Moline, fireman, third class. United States Navy, approved December 10. 1921 (File No. 29372-4), it was likewise held that in the absence of definite facts showing that the claimant in each case did in fact have the disability complained of prior to his acceptance into the naval service a strong presumption that said disability had its origin prior to his entry into the naval service is not sufficient to warrant a conclusion that said disability was so incurred, but, on the contrary, it should be considered as having had its origin subsequent to the entrance of the claimant in the naval service. In the case of Moline the facts showed that he had apparently suffered from eye trouble for many years prior to his enlistment in the naval service, but there were no facts showing that he had the disability complained of prior to his entrance therein, and in the absence of facts showing that the particular disability complained of actually existed prior to his entrance into the naval service, it was held, in the absence of fraud and facts showing that it was due to his own misconduct, that it originated in the line of duty. 7. Reference to attached papers discloses not only an absence of affirmative facts showing that the disability complained of existed prior to the entrance of the claimant in the naval service, but it is shown by sworn statements of individuals who have known the claimant for a number of years prior thereto that his " condition of health prior and up to the date of his enlistment was good." 8. In the case of Badolato, above referred to. this office held that " concern ing so much of the diagnosis of this case as states that the patient is suffering from ' dementia prseeox ' this office has no recommendation to offer for the reason that it considers that the determination of the disease is a matter timing wholly within the jurisdiction of the Medical Corps. This office, however, is unable to concur in so much of the diagnosis in this case as states that the No. 4. 689 DIGEST OF DECISIONS. ' dementia precox ' did not occur in the line of duty, the same being a matter to be determined under the law and the facts." 9. Applying the above rule to the case under consideration, this office has no recommendation to offer concerning so much of the diagnosis of this case as states that the claimant was suffering from " constitutional psychopathic state." but in regard to the matter of the reasons assigned this office finds itself in disagreement. For example, it is stated by the board of medical survey that the patient was turned over to the psychiatric division because he had been telling girls in Norfolk, who were wearing a part of the naval uniform, that they were doing so Illegally and would be arrested. "He had no authority to do this." Reference to section 125 of the national defense act, approved June 3, 1916. which was in force at the time when the conduct of the claimant complained of took place, discloses that it was unlawful for any person not nn officer or enlisted man of the United States Navy, to wear the duly prescribed uniform of the Navy, or any distinctive part of such uniform, or a uniform any part of which is similar to a distinctive part of the duly- prescribed uniform of the United States Army. Navy, or Marine Corps, the penalty prescribed being a fine of not exceeding $300 or imprisonment not exceeding six months or both such fine and imprisonment. The further state ment that claimant had no authority to do this is likewise in error for the reason that being a citizen of the United States, as well as an enlisted man in the naval service, he was peculiarly authorized to advise individuals against the wearing of any distinctive part of the Navy uniform or a uniform any part of which was similar to a distinctive part of the Navy uniform. 10. After a full and complete consideration of all the matter presented in attached papers, and the opinions of the Attorney General, and decisions of the court relative to the question of line of duty, this office is of the opinion that whatever disability the claimant may have been suffering at the time of his discharge by medical survey must be held to have been Incurred In the line of duty, and you are advised accordingly. /s/ A.

Ditmars, curator of reptiles and asistant curator of mammals in the New York Zoological Park. The Macmillan Co., New York, 1922. Here is a rare book giving a general survey of the reptiles of botli hemispheres and written in a popular vein by one who has made a life study of the subject. The large collection of living reptiles to be seen in the New York Zoological Park was created by the author of this most readable book, and it is doubtful if anyone knows more of habits of the reptiles of the New World than he does. The reptiles found upon the earth to-day comprise mainly the tortoises, turtles and terrapins, the crocodiles and alligators, the liz- Rrds, and the snakes. The author necessarily has treated this large class of animal life by limiting his descriptions to representative groups and saying little of individual species. Interwoven with the descriptions of the anatomical characteristics of the various groups of reptiles are anecdotes of the author's search for specimens and of the methods employed in capturing them. Throughout the foxt is scattered much interesting information concerning the habits and the feeding, general care, and treatment of reptiles in captivity. Fact and fictjon has been carefully separated, and the story of the 691 692 Vo.. XVIi book: notices. reptiles is so well told that it should be interesting to the general reader. A notable feature of the book is over 200 photographic illustrations. These apparently are from the author's camera, and each is a study of reptilian life. They have been so carefully prepared that the distinguishing characteristics of each creature photographed are easily noted. Many persons are interested in turtles and tortoises: a smaller number have a liking for lizards and small crocodilians, but few people care to be associated with snakes. However, the snakes seem to have been the subject of the author's favorite study, and he has devoted the latter half of the book to them. He realizes that many of his readers will encounter the story of the ophidians with aver sion, but it is his hope that ere the book is finally closed " a per sistently reigning and unjust prejudice may be completely shattered by the explosion of a long train of erroneous theories, when the snakes have been described as they truly are, and the clean, grace ful, and wonderful phases of their varied structure have been faith fully portrayed by the camera." The snakes are of great economic importance, destroying rats and mice, and the prevalence of many snakes about the buildings on a farm comes from the presence of these rodents in them. Many snakes are surprisingly gentle in their attitude toward man. making beautiful and interesting pets. Many are hardy, not at all par ticular as to the .character of their food—eating dead animals or strips of raw beef covered with well-beaten eggs—and live for years in captivity. Healthy and well-nourished snakes shed their skin at intervals of about two months, or sometimes at shorter periods. The snakes either lay eggs or produce their young alive. The common garter snake is viviparous and sometimes produces as many as 75 young in a litter. This explains why this variety is so numer ous in our country in spite of the fact that the farmer boy kills every one he encounters. The young of the poisonous snakes are provided at birth with perfectly formed venom-conducting fangs and glands; they are just as dangerous in proportion to their size as their parent. All young snakes at once shift for themselves after birth or hatching. " Though poisonous snakes are common enough in many parts of the world, the danger from them is not nearly so great as imagined. In India, where a large part of the population goes barelegged, the estimated number of human lives lost each year is about 20,000. Conditions are very different in the United States, though the various species of rattlesnakes, the cop perhead snake, and the formidable water moccasin teem over vast No. 4. 693 BOOK NOTICES. area. Records of snake bites are exceedingly rare in North America." In the pages of this book one who has served in the Navy a reason able number of years will encounter the descriptions of many of the reptiles whom he has probably met in various parts of the world. Among the chelonians we find several friends of our boyhood days—the snapping turtle, " a bold and aggressive animal, not hesitat ing to attack waterfowl, which it drags beneath the surface to drown, when it tears up the prey by means of the combined efforts of strong mandibles and forefeet." This is the fellow who occasionally " takes the bait of a fisherman, when its prodigious struggle to free itself from the hook leads the excited sportsman to believe that he has made a finny capture beyond all power of imagination." The little yellow-spotted turtles that bask along the banks of pools; and the little terrapins which "may be seen sunning themselves in rows on derelict timber, from which they tumble clumsily when frightened. Once in the water their broadly webbed feet take hold and they scurry to the bottom, where they hide in the aquatic vegetation. When they again approach the surface, it is with the greatest caution. Only the snout and eyes are thrust above the water. In this position they paddle about inspecting the outlook until thoroughly satisfied that all danger has gone, when, one after another, they clamber on their favorite roosts for another sun bath." In wardroom tales of days long gone, one often hears mentioned a dish of which the diamond-back terrapin formed the principal in gredient. This creature used to be plentiful in the salt marshes along the coasts of North and South Carolina. They were compara tively cheap, but the market demand threatens their extinction, and a dozen 8-inch " diamond-backs " are worth to-day, according to the author, about $75. The tortoises are strictly terrestrial species of the Chelonia, and older officers may recall the giant tortoise, specimens of which were to be found on the Galapagos Islands until a few years ago, when a scientific expedition secured what its members believed to be the last survivors of the tortoise colony. The author describes the love making of these immense creatures, of which specimens weighing over 300 pounds exist in his collection. Many of us are familiar with the sea turtles, which have an extensive distribution throughout the tropical and semitropical seas. They are the giants of the aquatic chelonians and never leave the sea except to deposit eggs on sand beaches. One of the sea turtles—the green turtle—is of world-wide renown as an article of food; an other — the hawk's bill turtle —furnishes the valuable " tortoise shell " which we always buy when in Japan. 4539—22 10 694 Vol. XVII BOOK NOTICES. In the section on the crocodilians the author answers the oft- asked question : " What is the difference between an alligator and a crocodile?" In reality the question is not a very important one, as among the 21 species of crocodilians there are but 2 members of the genus Alligator, one inhabiting North America and the other the Yangtze River in China. There is, however, a great difference in the temper and activity of alligators and crocodiles. "An enraged alligator will throw its head from side to side, bang the jaws to gether sonorously, and violently swish the tail, but a man with steady nerves may approach within a few feet of the animal, throw a noose over the head, tie the jaws together, push a pole toward the body, then by successive nooses pulled backward over the head and forward over the tail, splint the animal to the pole so it is entirely powerless. . . . Such proceedings would be abruptly terminated by a crocodile." The author describes his first meeting with a big fellow from Florida : " Driven out of the crate, the crocodile looked the picture of good nature. Standing away from what he thought to be the reach of his tail, the writer prodded the apparently slug gish brute with a stick to start it for the tank. Several things hap pened in quick order. With a crescentic twist of the body utterly beyond the power of an alligator, the brute dashed its tail at the writer, landing him such a powerful blow that he was lifted com pletely from the ground. As he left terra firma, an almost involun tary inclination caused him to hurl his body away from a pair of widely gaping, tooth-studded jaws swinging perilously near. Land ing with a thud on one shoulder, though otherwise unhurt, the writer threw himself over and over, rolling from the dangerous brute that was actually pursuing him on the run, body raised high from the ground. . . . Such is the average crocodile— an active, vi cious, and, above all, treacherous brute." The author explodes the popular supposition that an alligator re quires a long period of time to acquire maturity. That such is not the case has been demonstrated by a number of young alligators under his charge. " These outgrew one tank after another within a few years. It only takes four years for an alligator, from the time of hatching, to grow fully large enough to have a commercially valuable hide." Among the lizards we find manj' acquaintances, especially familiar to most of us being the little geckos wTith their thick-set body, broad, flattened head, stumpy tail, and the round disk or " sucker " on each toe, which dart about the ceilings of tropical quarters after the lamps are lit in search of insects attracted by the light, and whose small white eggs the children often find in crevices about the house and place in a tumbler wrhere the hatching process may be watched. No. 4. 695 BOOK NOTICES. Probably next best known are the iguanas, of which there seem to be many species and which are so plentiful in tropical forests. It appears that fine specimens of the common iguana may be purchased from dealers in the United States for $3 or $4 each ; but the rhinoc eros iguana, a far more showy creature, costs about $25. As it is found only in Haiti and Porto Rico, I record this bit of commercial information for the benefit of any member of the marine expedi tionary force on duty in the " Black Republics " who may wish to turn it to account. Rhinoceros iguanas might prove a better ven ture than parrots or monkeys. The chameleons of course receive their share of attention in the discussion, and the author records several interesting facts about them. Many lizards, especially those from desert regions, require great heat in captivity, and the author tells us that he has seen certain specimens " dashing about [their cage] with a great show of anima tion when a Fahrenheit thermometer registered 110°." Many captive desert lizards live but a short time. They die from a lack of water. It was quite by accident that the author discovered how such specimens may be saved, for they will seldom drink from a pan or lap the dewlike drops of water from the vegetation in the cage. His specimens stubbornly refused water, became emaciated, and were slowly dying. One day when certain cacti in the cage were being watered a remedy for the trouble was discovered. A few drops of water were accidentally scattered over the lizards' backs, where they were instantly absorbed. Taking this as a valuable hint, the author had all the lizards thoroughly sprayed with a " mist " nozzle. A change was soon noted. After a few days spraying the reptiles took on plumper outlines, feeding with more energy. It is possible that in their desert homes the quick change of temperature, influ enced by day and night, may produce a certain condensation of mois ture, like a dew, thus enabling the thirsty skin of these little animals to absorb the needed fluid. From the decks of small gunboats, cruising leisurely off the west coast of Mexico and Central America, one may often see a sea snake somewhat under a yard in length, jet black or rich brown above—on the upper half of the body—while the lower half is bright yellow. This, according to the author, is the yellow-bellied sea snake, Hydras platunix, and it occurs only in these waters. Reptiles of the World is a book which should be in the library of every naval vessel where it would be accessible for reference to all those interested in identifying and studying the reptiles encountered in travels about the globe. It is highly recommended to all who might wish to make the study of the reptiles a hobby, as some medi cal officers have done. (w. m. k.) 696 Vo'. XVII BOOK NOTICES. The Pbactice of Medicine, by A. A. Stevens, A. M., il. D., professor of applied therapeutics in the University of Pennsylvania. W. B. Saunders, Philadel phia, 1922. The writer of this volume on practice is peculiarly fitted to pre pare a work worthy of careful consideration by the medical pro fession of the English-speaking countries by reason of his teaching ex perience in the University of Pennsylvania, and his vast clinical experience derived from his connections with the great hospitals of Philadelphia. In the preparation of the book, Doctor Stevens de sired to present descriptions of the various internal diseases which should accord with the present state of our knowledge, and which, though concise, should give to the student and the practicing physi cian the most necessary points in pathology, diagnosis, and treat ment, and he has succeeded in his wish to a remarkable degree. In looking at a work of this size—the volume contains 1.106 pages—one does not often think of the labor involved in its produc tion. The manuscript must be written and sent off to the publisher, in whose establishment it is made ready for the press —the copy is set up in type, galley proofs are struck off, and, after these are cor rected, page proofs, which are submitted to the author for final cor rection, are printed. After all errors have been eliminated from the text and the index and illustrations have been prepared, the pages are printed and sent to the bindery, from which the finished product issues. These various processes take time, yet in spite of the months required for preparation, this volume is singularly up to date. A glance through the pages reveals mention of many of the very latest advances in the practice of medicine. The work is intensely practical, a prominent feature being the excellent outline of treatment which concludes the discussion of each disease, and it gives promise of being a successful rival of the master piece of Osier, whose pupil Doctor Stevens once was and to whom his book is dedicated, (w. m. k.) Symptoms of Visceral Disease, A Study of the Vegetative Nervous System in its Relationship to Clinical Medicine, by F. M. Pottenger, A. 31., M. fl.. LL. D., F. A. C. P. Second edition. C. V. Mosby Co., St. Louis, 1922. The one outstanding need of modern medicine, according to the author of this important contribution to medical literature, is accu rate clinical observation and interpretation; and the clinician who must weigh the value of clinical data gathered from all sources and give the final opinion of the case, should not only be familiar with iaboratory methods and be able to properly interpret the findings, but he should cultivate the habit of accuracy in the observation of his patient and be able to understand the meaning of symptoms which point to departure from the normal functioning of the body. No. 4. 697 BOOK NOTICES. In this book the author has attempted to interpret, so far as may be possible in terms of visceral neurology, symptoms which are found in the everyday clinical observation of visceral disease, and to show how pathologic changes in an organ affect other organs and the body as a whole through the medium of the visceral nerves. It might well be called a study in pathologic physiology. As the author remarks in the preface, the work is largely a discussion of " viscerogenic " reflexes; and, as such, prompts the reader to consider carefully the problems connected with the vegetative nervous system and im presses upon him the importance of careful clinical observation and analysis. " While the importance of the vegetative nervous system has long been known to physiologists, clinicians generally have ignored it and failed to see its intimate relationship to clinical medicine; but it is the key which unlocks the door to many of the secrets of visceral ac tivity. An understanding of the vegetative nervous system and the activities of the endocrine glands will explain to the clinician most of the physical acts connected with visceral function and furnish the bridge between the pathologic changes in tissues and the expres sion of the disease in altered organic function. In other words, the vegetative nerves and the products of the endocrine glands are the mediums through which visceral symptoms are expressed." Although the study of the vegetative nervous system is briefly pre sented by the author, it is sufficiently complete to furnish " the essen tial facts which one should have in order to understand the manner in which body activities, both physiologic and pathologic, express themselves through it." The volume is arranged in three parts, the first dealing with the relationship between the vegetative nervous system and the symp toms of visceral disease : the second, with the innervation of impor tant viscera and a study of the more common viscerogenic reflexes; the third, with the anatomy and physiology of the vegetative nervous system. The book should be read in conjunction with Mackenzie's Symp toms and Their Interpretation, to which the author refers fre quently. (W. M. K.)

The Writing of Medical Papers, by Maud H. Hellish, editor of the Mayo, Clinic Publications. W. B. Saunders Co.. Philadelphia, 1922. Mrs. Mellish says in her introduction to this valuable little hook: " Many men and women who, unfortunately, do not possess the art of writing and have not acquired its usable substitute, the craft of writing, have chosen medicine as a life work, for success in which they should be able to write well for the medical profession. They desire, therefore, to acquire the craft of writing with the least pos sible effort or delay. For these there is a need, not for new manuals, but for a handbook adapted especially to their profession and in cluding the essential points to be found in general textbooks." So in order to assist those who are struggling in their attempts to ex press their thoughts on paper with brevity, accuracy, clearness, and in accordance with the accepted forms of the present day. she has prepared a small volume which is crowded with useful knowledge pertaining to the craft of writing. The book contains short discussions of the misuse of terms and words, tin advantage of the acquisition of a large vocabulary, the use of italics and abbreviations. The chapter on punctuation is especially helpful when one is in doubt as to what marks to use and when to use them. In a chapter on miscellaneous grammatical notes and pitfalls in diction, the writer points out some errors which are the result of our careless habits of thinking and forgetfulness of the common rules of grammar. The latter half of the volume is devoted to a discussion of the technic of the preparation of a satisfactory paper, in which subject matter, length, arrangement, construction of the paper as a whole as well as that of the paragraph and sentence, the use of references, the revision of the manuscript, proofreading, the use of quoted material and respect for copyrighted matter are helpfully com mented upon. The volume closes with a list of the standard abbreviations for the titles of medical journals which should always be used when No. 4.

Mrs. Mellish has gone to great pains to tell her reader just what to do in order to prepare a readable paper, but, better yet. all through the volume she has been careful to tell him what not to do, which fact adds greatly to the value of her book. This little volume will be helpful to the naval medical officer not only in preparing articles for publication, but in the preparation of his official correspondence, with which one can not be too careful.

REMAEKS ON DEEP-SEA DIVING. By G. B, W. Frknch, Lieutenant Commander, Medical Corp*, United States Navy. One of the important duties of the medical officer is the physical examination of men selected for deep-sea diving. In selecting divers, only men of high physical standard should be chosen, i. e., men free from diseases of the ears, heart, lungs, blood vessels, and kidneys, and men of good muscular development. Two other fac tors are to be considered in the physical qualifications of a deep-sea diver: (a) Degree of fatness; (b) age. Moderately stout men and middle-aged men are more disposed to caisson disease than young, slim, small, or wiry men. The degree of fatness is the more im portant factor. Nitrogen is several times more soluble in fat than in the ordinary body tissues, and on decompression the fat gives off its nitrogen more slowly. Hence a stout person is more liable to caisson disease. Men of middle age are more inclined to fatness and therefore more predisposed to caisson disease. The respiratory ex change in middle-aged men is slower, and in moderately fat men the blood, instead of being one-twentieth the body weight, is nearer one-thirtieth, and hence elimination of nitrogen in solution of body tissues would be slower than in the small, slim man. Arteriosclerosis is a dangerous factor, and men with even mod erate or slight arteriosclerosis should not be chosen. Ear disease is a bar to diving. This is especially true of any trouble that interferes with the patulousness of the Eustachian tubes. Frequently men with even a slight cold, owing to congestion of these tubes, are unable to clear their ears; i. e., equalize pressure on both sides of the ear drums. Pain from unequal pressure on the drums is severe. If, despite the warning of ear pains, the diver is unable to clear his ears and persists in descending, a rupture of the ear drum is possible. 701 702 Vol. XVII DIVISION OF PREVENTIVE MEDICINE. Air pressures exceeding three or four atmospheres (66 to 99 feet sea water) have an irritant effect on the lungs. Hence, it is evident the lungs must be sound and the individual free from tuberculous tendencies. The best type for diving work is the young (20 to 30 years of age), small, thin, wiry man of phlegmatic temperament. The circulation of blood is faster in his case, he desaturates more quickly, and is less inclined to caisson disease. PHYSICAL EXAMINATION. The medical officer should examine all candidates for the course of instruction at the diving school. They must come up to the physi cal requirements before they are considered eligible for instruction. Qualified divers should be examined at frequent intervals, and a special physical examination should be made in the case of all men prior to each diving operation, especially if the depth of the water is over 40 feet. Under ordinary conditions divers over 40 years should not be permitted to dive in water over 15 fathoms in depth. AIR SUPPLY TO DIVERS. The medical officer should assure himself that a sufficient amount of air of proper quality is furnished the diver for helmet ventilation. The minimum air supply in cubic feet per minute for any given depth may be computed by the following formula : £==1.5(1+F(0.0303)), in which S is the required air supply in cubic feet, measured at the surface, and F is the number of feet the diver is below the surface. To enable the diver to perform hard work, arrangements should be made for supplying three times this quantity of air, if practicable. AIR SUPPLY FROM MANUALLY OPERATED PUMPS. Under usual service conditions the air supplied to divers is fur nished by two-cylinder, double-acting, manually operated air pumps. The latest type of pump is the Mark III, which has a capacity of 405 cubic inches per revolution when 100 per cent efficient. Other types of pumps in service are Mark I ; Mark I, model 1 : Mark I, model 2; the Mark II; and the Mark II, model 1. The capacity of the Mark I is 277.7 cubic inches per revolution, when 100 per cent efficient. The capacity of the Mark U models 1 and 2. and Mark II. and Mark II. model 1, is 296.3 cubic inches per revolution when 100 per cent efficient. The efficiency of the service of manually operated diving air pumps will be found to vary greatly. The greater the depth or pressure , against which pumps have to be worked, the greater will be the loss No. 4. 703 DIVISION OF PREVENTIVE MEDICINE. of efficiency. The efficiency of a pump will depend largely on the care and upkeep the pump has received. Tests on various service pumps against pressure as low as 20 pounds per square inch has shown efficiency of pumps varying from 30 to 90 per cent, and at higher pressures —75 pounds per square inch —efficiency has been as low as 5 per cent. It is essential that the efficiency of the pumps used should be known in determining the amount of air supplied to the diver. Inefficient pumps should not be used until properly repaired. As every foot depth of sea water exerts a pressure of 0.445 pound per square inch, and as loss of efficiency increases with pressure, it is necessary that pump efficiency be properly determined in all diving operations in water in which the depth is greater than 30 feet, and especially so if the pump has been in service for any considerable time. DETERMINATION OF PUMP EFFICIENCY. The percentage efficiency of a diving air pump can be practically and approximately determined by pumping air into a reservoir or air tank of known capacity, noting the number of revolutions re quired for the different pressures, and then making a mathematical comparison of the results thus obtained with the theoretical capacity of the pump at test pressures. When T= theoretical capacity of pump in cubic inches per revo lution ; Potest pressure in pounds per square inch by gauge; r=capacity of test tank, air hose, and air space in pump connections ; 14.7 = pressure in pounds per square inch of 1 atmosphere; ^"^theoretical number of revolutions required to charge test tank to P; A'=The number of revolutions actually required to charge test tank to P— L CP-R T 2. 10o5=per cent efficiency. 3. 100 minus per cent efficiency equals loss efficiency. The theoretical capacity of the various two-cylinder, double-act ing air pumps in service are as follows: Mark I (8J-inch diameter cylinders, 6-inch stroke) is 277.7 cubic inches. Mark I, model 1 (4-inch diameter cylinders, C-inch stroke) is 296.3 cubic inches. Mark I, model 2 (4-inch diameter cylinders. C-inch stroke) is 296.3 cubic inches. 704 Vol. XVII DIVISION OF PREVENTIVE MEDICINE. Mark II (4-inch diameter cylinders, 6-inch stroke) is 296.3 cubic inches. Mark II, model 1 (4-inch diameter cylinders, 6-inch stroge) is 296.3 cubic inches. Mark III (4^-inch diameter cylinders, 74,-inch stroke) is 405 cubic inches. The capacities of air spaces contained in the air connections (capacity of branch pipes, air reservoirs, gauge pipes, etc.) of the Mark I ; Mark I, model 1 ; Mark I, model 2 ; and the Mark III diving air pumps are approximately 83 cubic inches each. Those for the Mark II and the Mark II, model 1, are approximately 43 cubic inches in each. The capacity of a 50-foot length of standard diving air hose (one- half inch internal diameter) is 117 cubic inches. For proving the efficiency of diving air pumps in accordance with the foregoing method, a test tank of 1 cubic foot capacity is furnished with all new diving apparatus. In using the test tank as a reservoir for measuring the volume of air furnished by a diving pump, the capacity of the air-hose con nection between the tank and the pump must be taken into considera tion when computing the capacity of the testing reservoir. For convenient reference the following table has been compiled. This table shows the percentage of loss of efficiency of the two- cylinder, double-acting, diving air pumps at various revolutions when tested to 100 pounds pressure per square inch, in the manner pre scribed, using a test tank of 1 cubic foot capacity and a 50-foot length of air hose between the tank and a pump: Revolution?.

DIVISION OF PREVENTIVE MEDICINE. 705 ■ ! i i When testing air pumps for efficiency according to this method, using a test tank of 1 cubic foot capacity, errors are easily made in recording the exact number of revolutions required for a given pres sure ; therefore, each test should be repeated two or three times, and the average results thus obtained should be taken as the true result. On account of the heat generated when compressing air, and the con sequent increase in volume due to expansion on account of heat, cool ing water should always be used in the water cistern of diving air pumps when they are being operated against pressure. The specifications for diving air pumps require that prior to accept ance they shall prove at least 80 per cent efficient when tested in accordance with the foregoing method, immediately after having been tested for endurance against a pressure of 100 pounds by gauge for a period of one hour. DETERMINATION OF PUMP'S REVOLUTIONS TO FURNISH NECESSARY AIR SUPPLY TO DIVERS. Knowing the capacity and efficiency of the diving pump, the r.umber of revolutions per minute necessary to operate the pump to furnish the proper air supply to a diver can be determined as follows : When Z)=depth of sea water, in feet, to which dive is made; Ar=number of cubic inches of air the pump will furnish per revolution, measured at atmospheric pressure; /?=number of revolutions per minute required of pump to furnish 1.5 cubic feet (2,592 cubic inches) of air per minute, measured at atmospheric pressure; X=number of revolutions per minute required of pump tc furnish minimum allowable air supply (1.5 cubic feet) (2,592 cubic inches) per minute at D— 2592 _ -y— *• R(l + £(0.0303)) = AT. If the efficiency of a diving air pump is less than 100 per cent, and its actual per cent efficiency at the equivalent absolute pressure at D is represented by a symbol as E, then : 1005(1+ D(0.0303))_v E As the value of N for the various types of two-cylinder, double- acting, diving air pumps, previously referred to when 100 per cent efficient, is 277.7 cubic inches, 296.3 cubic inches, and 405 cubic inches, then R must equal 9.33, 8.75, and 6.4 revolutions, respectively. Multiplying these respective values by the coefficient 0.0303, the following results are obtained : 0.283, 0.265, and 0.194. Hence, to determine any number of revolutions per minute, it is necessary to run any of these pumps to furnish the minimum allow- 706 Vol. XVII DIVISION OF PREVENTIVE MEDICINE. able air supply (1.5 cubic feet per minute) for one diver at any depth, proceed as follows : Diving air pump, Mark I.—Divide 100 per cent by tbe actual per cent efficiency of the pump at the equivalent pressure to which the dive is made, and multiply the quotient thus obtained by the sum of the product of the number of feet depth of sea water and the constant. 0.0283, added to 9.33 (number of revolutions required to deliver 1.5 cubic feet of air at atmospheric pressure). Diving air pumps, Mark I, model 1; Mark I, model 2; Mark II: Mark II, model 1.—Divide 100 per cent by the actual per cent effi ciency of the pump at the equivalent pressure to which the dive is made, and multiply the quotient thus obtained by the sum of the product of the number of feet depth of sea water and the constant. 0.265, added to 8.75 (number of revolutions required to deliver 1.5 cubic feet of air at atmospheric pressure). Diving air pumps, Mark III.—Divide 100 per cent by the actual per cent efficiency of the pump at the equivalent pressure to which the dive is made, and multiply the quotient thus obtained by the sum of the product of the number of feet depth of sea water and the constant, 0.194, added to 6.4 (number of revolutions required to deliver 1.5 cubic feet of air at atmospheric pressure). For example : Diving air pump, Mark III, 80 per cent efficiency ; depth of sea water, 66 feet. How many revolutions per minute should the pump be run to furnish the minimum allowable air sup ply (1.5 cubic feet of air per minute) to a diver working at that depth? 100-^80X (66X0.194-f6.4) =24 revolutions per minute. The maximum rate of pumping that it is possible to maintain by a pumping crew over a practical period of time is about 30 revolutions per minute, and as the depth or equivalent pressure increases this becomes less and less. Therefore, if the revolutions required are in excess of the number it is possible to maintain the work should be divided between two or more pumps. What arrangements may be made for supplying the requisite amount of air to one diver working at a depth of 168 feet when diving air pumps, Mark III, each 80 per cent efficient, are used? (100-^80) X (168X0.194+6.4) =48.7, or practically 49 revolutions per minute to furnish 1.5 cubic feet of air to one diver with one pump, or 24.5 revolutions per minute with two pumps.1 1At this writing practically the only diving pumps in service In the Navy are the Mark III. However, in remote stations and older ships some of the older service putnps, Murk I and II, may be encountered. yp • No. 4. 707 DIVISION OF PREVENTIVE MEDICINE. When utilizing manually operated diving air pumps to furnish air for divers, the following conditions should be observed : (a) Arrangements should be made to furnish at least the mini mum allowable air supply (1.5 cubic feet per minute, measured at the absolute pressure to which the dive is to be made) to each diver, and, if practicable, a reserve air supply. (b) Arrangements should be made to insure the dispatch of a relief diver. (c) Except in shallow depths and where there is no danger of divers becoming foul of obstructions on the bottom, more than one diver should not be permitted to dive when using air from the same diving air pumps or group of diving air pumps. (d) The rate of pumping should be regular. (e) If the air being supplied to a diver is uncomfortably warm, cold water should be placed in the water cistern of diving air pumps, and kept cold by the addition of ice, if necessai v. AIR SUPPLY PROM POWER COMPRESSORS AND STORED COM PRESSED AIR. For safety, ease of operation, and economy, a power compressor or stored compressed air is used to furnish air for helmet ventila tion when the diver reaches deep depths. By the use of tliis appara tus great depths are attainable over long periods of time. In the hands of the unskilled this is a dangerous procedure, and those who have not been specially instructed in the practice and use of the power compressor or stored compressed air for diving should not be allowed to utilize this method. In using power compressors or stored compressed air in diving, the air supply in cubic feet per minute, measured at surface, for any given depth is calculated at 4.5 (l-\-F (0.0303), in which F is the number of feet the diver is below the surface. The technic of the air supply is as follows: Air is supplied to the diver from a tank (from 1 to 5 cubic feet capacity) in which the air pressure is maintained constantly at 25 to 50 pounds per square inch above the greatest pres sure necessary for the greatest depth at which the diver is to descend. The diver controls the flow of compressed air from this tank by means of an air control valve which is interposed in the diving hose, 3 feet from the helmet, and fastened to his breast plate. The pressure in the tank is kept constant by low-pressure (100 pounds per square inch), automatically controlled, large-ca pacity, power-driven air compressors, or by high- pressure compres sors, 2,000 to 3,000 pounds per square inch, of sufficient capacity, or high-pressure (2,000 to 3,000 pounds per square ;nch) stored com 708 Vol. XVII DIVISION OF PBEVENTIVE MEDICINE. pressed air (torpedo air flasks) ; in which case, a hand-operated (not automatic) reducing valve and by-pass are interposed on the line to the tank from which the diver takes his air. AIR SUPPLY FROM HIGH-PRESSURE ACCUMULATORS. High-pressure accumulators, such as the air accumulators of the torpedo installation on board vessels, may be used in diving opera tions. When connections are made with accumulators, diving opera tions are to be conducted directly from or in the immediate vicinity of the diving vessel, thus obviating the necessity for the use of a long length of air hose and its accompanying dangers. When the accumulators are of sufficient capacity, the air necessary for the diver should be taken from accumulators already fully charged to maximum capacity. When the capacity of the accumulators is in sufficient for the depth to be accomplished, the air compressor shall be in operation when necessary, and care taken to see that the water- cooling system is intact in order to insure a cool air supply. The capacity of the air compressor and the accumulators must be known and taken into consideration when calculating the air supplied to the diver. Under no circumstances should the diver be permitted to dive to the limit of his air supply, no matter what the method is in use at the time. Sufficient air must always be held in reserve to enable a relief diver to go to the assistance of the man under water. To increase the capacity of the air accumulators on board ship, the tor pedo air flasks can readily be utilized by connecting them up to the air line with stop valves opened. AIR SUPPLY FROM TORPEDO FLASKS. Torpedo air flasks may be utilized to furnish air to divers when deep-diving operations are to be conducted at a distance from the diving vessel. In the use of this method, at least three or more flasks must be connected to the manifold ready for use, and one flask held in reserve, to be used only in case of special exigency, as in the case of a fouled diver. Not more than two divers shall be permitted to dive from the same boat. The pressure in the working flasks, as indicated on the high-pressure gauge, shall not be permitted to fall below 220 pounds per square inch in excess of pressure at which the divers are working while on the bottom. After they are clear of the bottom and safely on their way to the surface the third flask may be opened. In case it should be found impossible to obey these instructions the reserve flask may be opened. However, at the same time a reserve supply of air in another boat must be immediately brought up and connected to the manifold. Under these conditions the duration of air supply from one flask is calculated as follows: Xo. 4. 709 DIVISION OF PREVENTIVE MEDICINE. 6'=capacity of one air flask in cubic feet. A= atmospheric excess pressure in air flask. D= number of divers. #=number of atmospheres' excess pressure to which dive is made. Allowing 1 air flask atmosphere for charging testing tank, air e, and helmet to E; 4.5 cubic feet to each diver per minute measured at absolute pressure, or El atmospheres; and reserve pres sure of 220 pounds per square inch, or about 15 atmospheres, to remain in the air flask in excess of that in which the divers are working while on bottom, or E, the calculation of time of air supply is as follows: g D(E-\-t)^ " equal duration of supply in minutes. AIR SUPPLY FROM LOW-PRESSURE ACCUMULATORS. The method of supplying air to divers from low-pressure accumu lators is applicable to vessels or stations equipped with gas-ejector systems —diving vessels, navy yards, and so forth. In this method the arrangement is practically the same as for diving with air from high-pressure accumulators. The air pressure in the ac cumulators is maintained steadily by large-capacity, low-pres sure, steam, or electrically driven, automatically controlled air compressors. The capacity of the compressors is such that there is never a question of shortage of air supply, the maximum depths to which divers will be able to descend will depend upon the pres sure of the air. There is no accurate method of determining the exact amount of air passing through the diver's helmet in this method of diving, and the only means of knowing whether adequate ventilation is being maintained is by the diver's physical well-being, and the percentage of C02 in the air of the helmet. When utilizing air from air accumulators or air flasks the follow ing conditions are essential: (a) The temperature of air must be such as not to cause discom fort to the diver. (b) The air in the accumulator must be free from noxious fumes and as near standard purity as possible, i. e., contains as near 0.04 of 1 per cent C02 as practicable. In utilizing air from high-pres sure accumulators it must be remembered that the air in the cylin ders of the compressors is greatly heated in charging the accumu lators, and oil with a high flash point must be used, castor oil if possible, so that no flashing in the cylinders will take place, pro- 4539—22 11 710 DIVISION OF PREVENTIVE MEDICINE. Vol. XVII ducing CO and C02. As little oil as practicable should be used in the cylinders of a diving pump. (c) Thirty to fifty pounds pressure per square inch in the testing tank above water pressure (at the depth of the dive) must be main tained to insure proper ventilation of the helmet. (d) The reserve air supply must always be maintained in case of accident to compressors, and so forth, to insure a proper stage decompression for the diver. TIME UNDER WATER AND ASCENT OF THE DIVER. The medical officer should recommend the time the diver shall spend under water ; and if working at any considerable depth, he should as sure himself that the decompression, i. e., the ascent of the diver, is properly managed. In deep wa^er, time under pressure should be made as short as prac ticable, as the greater the length of stay the longer will be the time spent in the ascent. The cardinal essential point in connection with the ascent of a diver is a proper and efficient decompression, so managed as to eliminate the possibility of caisson disease. For diving, the most efficient practical method of decompression is that known as stage decompression. The following tables are constructed on this theory and have been proved safe. While they are not guaranteed to protect a diver from a moderate attack of "bends," a diver so decompressed in accordance with them will be spared from any serious attack of caisson disease. In all diving operations, decompression, i. e., ascent in accordance with these tables, should be strictly followed and, except in special exigency, no diver should be brought to the surface faster than the time specified.

In selecting the decompression table for a certain dive (depth and time of exposure), the time of exposure shall include time of descent and time on bottom, and preference should be given the longer table. PRECAUTIONS AFTER A SECOND DESCENT. If a diver makes a second descent in deep water with an interval of less than three hours between the two dives his body will be more highly saturated with nitrogen at the end of the second dive, and extra care will be needed in bringing him to the surface. A safe rule is to take the combined time of the two dives and use a table for that exposure at the pressure at which the diver was working. The extra time is, however, only needed for the second half of the stops indicated in the tables. EMERGENCY ASCENTS. In case of accident or special exigency it may be essential to get a diver to the surface as rapidly as possible, even if an attack of caisson disease is threatened. Under these conditions the speed of the ascent will depend on : (a) Nature of the accident or emergency. (b) Depth and length of exposure at which diver has been working. (c) Whether or not means for treating or preventing an attack of caisson disease can be resorted to by sending the diver down again immediately or whether there is a recompression chamber ready for immediate use. In any case where a diver fails to answer his telephone or signal that diver should be started toward the surface immediately. A pause should be made at the first stage of decompression and an attempt made at communication; then, depending on the nature of the accident or emergency, the remainder of the ascent must be according to the judgment of the officer in charge. The emergency may be serious enough to warrant immediate ascent. If there is reason to suppose that the diver can be sent down "gain immediately or if a recompression chamber is ready for imme diate use. a chance should be taken on a fairly rapid ascent for the 'emaining distance. In case of very deep diving, when a recompression chamber is available and a rapid ascent becomes imperative, bring the diver 'it once to half the absolute pressure, keep him there for a period "f 20 minutes, if possible, or, if this is not possible, as long as prac ticable, then haul him to the surface, remove the helmet, life line, and air hose (cut them off the diver), place him in the recompres 714 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. sion chamber, then proceed as directed under " Treatment of caisson disease," removing the diver's dress and equipment in the chamber. ACCIDENT TO DIVERS— PREVENTION AND MANAGEMENT. The medical officer's services are often required for treatment of divers' injuries. Deep diving is an extremely hazardous occupation. Accidents are constantly occurring, and such accidents occurring in deep water are usually serious. Constant vigilance on the part of all concerned should be exercised. It is essential that the diving apparatus should be complete, in good condition, and in good work ing order, and that divers and "tenders" be specially qualified. Except under unusual conditions, no diving operations in deep water should be carried out without a proper recompression chamber. The accidents usually encountered in diving operations are as follows : (a) Asphyxia. (b) Squeeze. (e) Caisson disease. (d) Accidental blowing up. (e) Fouling. (/) Ear pains (bleeding from the ears). (ff) Bleeding from nose and lungs. (h) Mechanical injuries from external violence. (») Exhaustion. (j) Drowning. (k) Oxygen poisoning. In all accidents occurring in deep water it must be remembered that the diver can not, as a rule, be brought immediately to the surface on account of the danger of a quick and fatal attack of caisson disease, but may be brought immediately to the first stop or stage of decompression. On this account coolness and judgment are essential, as the effects of caisson disease may prove worse than the accident. If the recompression chamber is near and ready for immediate use, the diver may be hauled to the surface with a cer tain degree of rapidity, quickly placed in the chamber with an attendant, preferably a medical officer, and pressure applied to at least half the absolute pressure at which the diver was working. First aid or other treatment can then be given the diver within the chamber. The record for apparent safe ascents, with a recompression chamber ready for immediate use, was from 150 feet after a 30-minute ex posure. Men were brought to the surface immediately as a routine after an exposure of 30 minutes at 150 feet, quickly placed in a recompression chamber, pressure applied corresponding to the pres No. 4. 715 DIVISION OF PREVENTIVE MEDICINE. sure of water at 150 feet, and then decompressed according to the tables without ill effects. ASPHYXIA. Asphyxia is probably the most common accident occurring when (living under present service conditions, and most of the deaths oc curring as a result of diving are from this cause. Asphyxia is usually the result of a deficient air supply, but may result from sup plying air containing a large per cent of C02, resulting from flash ing of the lubricating oil in the cylinders of air compressors. It may result from the diving dress not being properly inflated, thus interfering with the diver's respiration. Its occurrence would be indicated by the diver ceasing to answer his telephone or signal after calling for more air. In case of insufficient or bad air supply the diver should remain perfectly quiet, operate his regulating escape valve, inflate his suit, and be prepared to ascend. Asphyxiation, except in case of a squeeze, is the result of C02 accumulation in the helmet. The diver is always warned of the excess of CO, by his increased respiration —i. e., panting, an uncomfortable feeling of warmth and sweating, headache, and clouding of the helmet windows from excess moisture from his breath. Fortunately a diver is cognizant of increasing C02 long before dangerous amounts are present, and it is of value to note that un consciousness occurs from it long before death. Attendants should always be warned of a deficient circulation of air through the helmet b>'-' (a) Decrease in the amount of air bubbles rising to the surface. (b) The decrease of the noise (caused by air escaping from the helmet through the regulating escape valve) audible over the tele phone. This is an excellent guide, telephone attendants becoming so efficient that by this method they are able to estimate the amount of air a diver is using. With these two guides alone, in conjunction with the diver's own sensations, except in case of accident, asphyxia from insufficient air supply is inexcusable. The danger of supplying air contaminated with C02 from flashing of oil in the cylinders is very unlikely, especially if any precautions at all are observed in using a good oil of high-flashing point in lubricating the compressors and the water- cooling system is working efficiently. Asphyxia from a slight squeeze, i. e., improper inflation of the dress, will only occur, as a rule, in case of an inexperienced diver. Divers learn to remedy this defect themselves long before they are allowed to attempt diving at any appreciable depth. 716 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. In cases where asphyxia is suspected, with the diver under water, he should be started immediately toward the surface. A pause should be made at the first decompression period, and another attempt should be made at communication. If there is no response from the diver he should be brought to the surface. Once at the surface, in case of asphyxia, fresh air should be given the diver as quickly as possible, by getting the face plate open, or by cutting the diving dress. In mild cases of asphyxia, where a man is still breathing, a few breaths of fresh air immediately relieves the condition. In a case where the man is apparently dead or unconscious, with feeble respira tion, artificial respiration should be started immediately. Do not wait to remove the helmet and dress but get an ingress of fresh air into the helmet and start artificial respiration. Squeeze. —Squeeze is usually the result of an accidental fall. If, through carelessness or culpable negligence, a diver should be per mitted to fall an appreciable distance under water, there would be a sudden increase of air pressure ; the helmet escape valve would be seated ; the air within the dress would be forced from it and into the noncompressible helmet ; the volume of air within the helmet dimin ishing with the increased pressure (Boyles's law). If this volume of air does not fill the helmet and equal the pressure of water at the depth to which the diver's body has fallen, the excess pressure exerted on the diver's body will tend to drive it into the helmet. The result is most apt to be a serious injury or immediate death for the diver. Falls from shallow to deeper depths are the most serious, as the relative difference in pressures is greater. For instance, if a diver at the surface, 14.7 pounds pressure to the square inch (abso lute), should fall 33 feet under water, every square inch of his body would have an additional pressure of 14.7 pounds, or 29.4 pounds absolute pressure, suddenly applied to it, a proportion of 2 to 1 over the pressure in the helmet. As the body has an area of about 2,000 square inches, the total pressure exerted on the diver's body and tending to drive him into the rigid helmet would be several tons (14.7). If, under the same conditions, the diver should have fallen from the surface to a depth of 66 feet under water, the increase in absolute pressure would have been trebled instead of merely doubled. So from the foregoing it is clear that a long fall from a shallow depth would result in a fatal squeeze for the diver. Falls from moderate depths to deeper depths under water are not apt to be so serious as falls from shallow depths ; that is, in a fall from the sur face to 33 feet the relative difference in pressure is as 1 to 2, while in a fall from 168 feet to 201 feet the relative difference in pressure is as 6 to 7. In the first case the column of air is reduced one-half and in the latter case only one-seventh. The effect of a fall under !fo. 4. 717 DIVISION OF PREVENTIVE MEDICINE. water is known as a squeeze. A squeeze may occur from other causes, however : (a) A diver descending ahead of his air supply, i- e., descending before the pressure within the dress is equal to the water pressure without. (6) Ruptured hose and a leaky safety valve. (c) Ruptured cuff of the dress and the diver raising hia arm, as when trying to reach the escape valve (squeeze in this case being slight, but enough to interfere with respiration). In cases of slight squeeze, as caused by the regulating escape valve being wide open and a minimum air supply, extra pressure is ex erted on the chest (suit flat). The air within the air passages is at a lower pressure than the pressure without, and the diver is forced to breathe against this extra pressure. Respiratory embarrassment results in a short while, and often a diver struggling up his descend ing line (buoyancy negative) under these conditions may bleed con siderably from the lungs and nose. Hemorrhage in this case is usually due to the rupture of small lung capillaries. The injury from squeeze can cause an almost immediate death. Any injury from squeeze is usually serious and as such demands immediate treatment. Get the diver to the surface as soon as it is deemed safe and remove the apparatus as gently as possible. The patient will usually be unconscious and bleeding profusely from the nose and mouth. Extreme cases have been known where the diver has been molded into his helmet, so that it was practically impos sible to remove it. Treat as for any internal injury, with shock. On account of the seriousness of this accident " tenders " must always observe the utmost caution to protect the diver from falling. The life line and air hose should never be permitted to skip through the hands by the run. If for any reason the diver finds himself in danger of falling he should signal for more air, or open wide his air-control valve and signal to the surface to " Hold on.'" The moment the danger is over, again regulate the air to prevent the counter accident of " blowing up." Although the effects of squeeze are much more serious than those of " blowing up," both should be avoided ; but if it is a matter of two evils, choose the latter. CAISSON DISEASE OR COMPRESSED AIR ILLNESS. In all deep-water diving with adequate air supply caisson disease is the commonest accident that the medical officer is called upon to treat. Caisson disease is the result of improper decompression; i. e., in the case of divers it is due to ascending too rapidly to the surface. The disease has many symptoms, at times manifesting itself in at tacks of dyspnea and unconsciousness, which may result in death in 718 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. a few minutes or hours; at times with paralysis of the motor and sensory nervous systems, involving as a rule the lower extremities and bladder. Mild attacks are more frequent, consisting of pain in the extremities and various parts of the body, vertigo, and so forth. The disease rarely occurs unless the pressure exceeds 20 pounds excess pressure (45 feet sea water). The greater the pressure and length of exposure the more frequent and severe will be the attacks of the disease, unless proper decompression has l>een re sorted to. The accepted theory as to the cause of caisson disease is that bubbles of nitrogen are liberated in the various body tissues, includ ing the blood, upon a decrease in pressure. In the anaylsis of over 3,500 cases of caisson disease the following classification was made : Per cent. 1. Cases showing pain in various parts of the body 88. 78 2. Cases with pain, also having local manifestations .26 3. Cases with pain and prostration 1. 26 4. Cases showing symptoms referable to the central nervous system : (1) brain .11 (2) spinal cord— (a) Sensory disturbances ( 6 ) Motor disturbances 2. 16 (c) Sensory and motor disturbances 5. Cases showing vertigo (staggers) 5.33 6. Cases showing dyspnrea and sense of constriction in the chest 1. 62 7. Cases showing partial or complete unconsciousness . 46 The fatal cases, of which there were 20 in number, occurred in those cases showing symptoms under 3, 4, and 7. Pain in abdomen, vomiting, subcutaneous hemorrhage, and girdle pains in the trunk are considered dangerous symptoms. With immediate recompression, and a gradual decompression, properly conducted, even in severe cases, the outcome is, as a rule, complete recovery. Without decompression, the number of recoveries is remarkable even in a very short while for low pressures, up to 50 pounds. Insufficient data are available on extreme pressures. PREVENTION OF CAISSON DISEASE. The prevention of caisson disease consists of— (a) Limiting time of exposure to high pressure. (b) Proper stage decompression. (c) Proper physical standard in the selection of divers. An attack of caisson disease may be delayed as long as 15 hours after the ascent. For this reason divers should always remain about the place where recompression can be applied until dismissed by the officer in charge. Symptoms vary from a slight attack of the "bends" to complete respiratory paralysis and death. If any unto ward symptoms are noted, as pains in the joints, cramps, staggers, No. i. 719 DIVISION OF PREVENTIVE MEDICINE. weakness, or paralysis of the arms or legs, inability to talk, asphyxia, or difficult respiration, the diver should be given immediate treat ment. In all deep-diving operations a compression chamber of some sort is essential, as there is no efficient means of treating caisson disease without one. Immediate recompression usually alleviates all symp toms. A submarine boat fitted with a diving compartment may be used to advantage for this purpose. In case a recompression cham ber is not obtainable, the only recourse left to the officer in charge is to cause the diver to be recompressed as quickly as possible by sending him down again to at least half the absolute pressure at which he had been working. If recompression, with a proper decompression, does not result in recovery, the case resolves itself into treating conditions that arise, remembering in all cases of paralysis there is practically always bladder involvement. THE MANAGEMENT OF THE MEDICAL AIR LOCK. For the prevention and treatment of caisson disease a portable recompression chamber might be had upon application. No diving operations in deep water should be carried out without a recom pression chamber of some sort except in case of special exigency. The maximum safe working pressure of the portable chamber at the diving school is 120 pounds per square inch, but it is rarely necessary to subject a patient to a pressure greater than 60 pounds. It is desirable that a medical officer, or at least somebody with experience in the prevention and treatment of caisson disease, should go into the chamber with the patient. It is of the utmost impor tance that there should be no delay in getting the patient under pressure. For this reason the attendants should be trained to take pressure, quickly. Dry clothing, blankets, medicines, etc., shall be kept in the chamber. In case of stoppered bottles, small openings through the corks should be made, so that pressure within and with out the bottles may be equalized, and thus prevent them from break ing as the result of unequal pressures. No volatile or dangerous liquids shall be stored in the chamber. An air lock is provided through which small articles may be passed in and out of the chamber. In case a diver has made a rapid ascent from deep water, but shows no symptoms of caisson disease, he must be hurried into the chamber as soon as possible and pressure raised to 60 pounds or less, this pressure being at least half the absolute pressure at which the diver has been working. He must be kept at this pressure for at least five minutes, after which, if no symptoms have developed, he can be decompressed according to the tables, corresponding to the 720 Vol. XVII. DIVISION OF PBEVENTIVE MEDICINE. time and depth of the dive, with an extra live minutes added to the total diving time for time in selecting the table. If symptoms of caisson disease develop, the patient should be taken immediately into the recompression chamber and pressure run up to 45 pounds with as little delay as possible. In most cases this will be sufficient to revive him. If, however, the patient does not show marked improvement, the pressure must be increased to 60 pounds. In one instance 75 pounds was necessary after a 300-foot dive. The patient must be kept at this pressure until any symptoms of circulatory embarrassment or dyspnoea have disappeared. Such symptoms disappear almost immediately; and if no other serious symptoms are present, decompression may be begun at once. If paralysis is present and does not pass off in two hours, it is useless to wait longer at high pressures. It must be remembered that exposure in the chamber exceeding 30 ppunds is likely to delay decompression very much. Decompression should be started as soon as the patient is relieved, pressure being allowed to fall at the following rate: When prcwure in the chamber is— Above 60 pounds Between 60 and 45 pounds Between 45 and 30 pounds Between 30 and 15 pounds Below 15 pounds No hard and fast rule can be laid down for a decompression rate, which will depend on the condition of the patient, how he stands the decompression, and also the pressure at which he was saturated. If the patient becomes ill again while the pressure is falling, decom pression must be stopped, and, if necessary, the pressure raised ; when the patient is better, pressure may be allowed to fall again but at a slower rate. If after decompression the patient again develops symptoms, the process of recompression and subsequent decompres sion must be repeated. ACCIDENTAL " BLOWING UP." Accidental "blowing up" may be injurious in various ways, as: (a) From deep depths, an attack of caisson disease may result. (b) From any depth, mechanical injury may result from striking some object, as the ship's side, etc. (c) from the possible fall back into deep water, with resulting " squeeze." Pressure ma}' be allowed to fall at a rate not faster than— Rapidly. 1 pound in 1 minute. 1 pound in 3 minutes. 1 pound in 5 minutes. ! 1 pound in 10 minutes. No. 4. 721 DIVISION OF PBEVENTIVE MEDICINE. Blowing up is caused by overinflation of the dress, or by the drag of the tide on the diver's lines, etc., sweeping the diver to the surface. In case of blowing up from depths beyond safety limits, the diver's valves should be regulated for him, as he will be unable to regulate them himself, and he should be sent down again as rapidly as pos sible (without subjecting him to a squeeze) to his first stage of de compression, at least. Decompression should then be commenced in accordance with the tables. A diver who has been " blown up " should never exhaust air from his helmet or dress until he is certain that the attendants have secured hold of his lines. FOULING. Fouling is caused by the diver's lines and hose becoming entangled with some obstruction under water, a situation which prevents him from ascending. It usually requires the services of another diver to clear the one fouled. Divers should be warned of the dangers from fouling. When a diver has become fouled and unable to ascend, death has resulted from shock and exhaustion. Also, prolonged exposure at deep depths may be followed by a fatal attack of pneumonia. EAR PAINS. Ear pains are due to inequalities of pressure on either side of the ear drum. They are experienced while descending under water, and are usually the result of inexperience, the diver not knowing how to clear his ears, i. e., equalizing the pressure in the Eustachian tubes and the outer side of the ear drums. Where the pressure on the outyr side has been sufficient to rupture the drum, bleeding from the ear and nose usually occurs. BLEEDING FROM THE NOSE AND LUNGS. These conditions are caused by the effects of a squeeze, but may result from great respiratory efforts when the dress is unusually flat or the air supply deficient. Treat as for "squeeze." MECHANICAL INJURIES FROM EXTERNAL VIOLENCE. There are many varieties of injuries which call for no special comment. The diver should be brought to the surface as soon as it is deemed safe and necessary treatment given. DROWNING. There are two cases on record of drowning in the diving dress in which the helmet became detached from the breastplate. This acci 722 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. dent can not happen if the safety catch at the back of a helmet is properly turned down. It is a common superstition among divers that if the dress is ruptured drowning will result. Such is not the case. Diving with helmets only has been accomplished in depths up to 140 feet as readily as with the complete apparatus, but the practice is deemed unsafe. As long as the air pressure within the helmet is maintained and the diver remains in the erect position, water can not enter the helmet and the diver will not drown. By simply clos ing the escape valve, air is forced down into the dress and will escape at the side of the vent. In case the dress becomes too full of water, it may be necessary to slip the weighted belt to facilitate ascent. OXYGEN POISONING. Air composed of 20 per cent oxygen exerts one-fifth of an atmos pheric oxygen pressure. At 10 atmospheres, the oxygen being one- fifth, would exert 2 atmospheres of oxygen pressure. Hence 2, 3. and 4 atmospheres of oxygen would equal 10, 15, and 20 atmospheres of air. Exposure of animals to a pressure of 170 to 180 per cent of an atmosphere of oxygen caused in a short time diminution in the power of the lungs to absorb oxygen. The tissues of the lungs showed intense congestion and an exudate into the alveolar spaces. High partial pressure of oxygen produces a marked irritant effect on the lungs, producing, first, congestion, and shortly afterwards hemorrhagic exudation and consolidation, i. e.. a typical pneumonia. The pneumonia is patchy if quickly developed, and general if slowly developed. , It requires about 24 hours' exposure to plus 7 atmospheres of air, or 168 per cent atmospheres of oxygen, to produce marked symp toms of pulmonary congestion. Experiments on monkeys showed no lung troubles in sequent ex posures every day for four or five hours at a time at this pressure. With exposures to oxygen pressure of 300 to 400 per cent, symp toms of oxygen poisoning quickly intervened and, in addition to the lung irritation, convulsions, tetanic in character, are likely to occur. There is but one case of oxygen poisoning known in the Navy, and this may have been a complication of caisson disease which re sulted after a long exposure to high air pressure —three hours of it at 120 pounds excess pressure. The diver developed a double broncho pneumonia. The prevention consists in limiting time of exposure at deep depths. Treatment is that of an ordinary pneumonia. HEALTH CONDITIONS OF THE NAVY. There has been little change in the health conditions of the Navy during the past month. The annual admission rate for all causes, entire Navy, for the five-week period ending September 9 was 576 per 1,000, as compared with 540 per 1,000 per annum for the four- week period ending August 5. The morbidity rate for diseases only during the same period was 510 per 1,000 per annum and for acci dents and injuries 66 per 1,000 per annum. The communicable diseases were slightly more prevalent during the past five weeks than at any time during the past four months; the annual admission rate for communicable diseases, exclusive of influenza and the venereal diseases, for the five-week period ending September 9 was 47 per 1,000 per annum. Of the communicable diseases malaria continues to cause the greatest damage; the mor bidity rate for this disease for the five-week period ending September 9 was 39 per 1,000 per annum. The following table gives the annual admission rate per 1,000 for certain communicable diseases for the current month of August, 1922, in comparison with the mean annual admission rates, month of August, for the four-year period 1918-1921, inclusive: Disease.

This may be better seen by comparing the table of communicable diseases for August with the tables published in previous issues of the Bulletin. 724 Vol. XVII DIVISION OF PREVENTIVE MEDICINE. During the past five weeks there has been a decided rise in the morbidity rates for the venereal diseases, the admission rate for this period being 142 per 1,000 per annum as compared with an average rate for the year of 114 per 1,000 per annum. The mortality rate for all causes, entire Navy, for the five-week period ending September 2 was 3.23 per 1,000 per annum. The annual death rate per 1,000 for diseases only was 1.83, for acci dents and injuries, other than drawning, 0.61 per 1,000 per annum, and for drowning, 0.79 per 1,000 per annum. VENEREAL PROPHYLAXIS IN EUROPEAN WATERS. By W. E. Bradbury, lieutenant. Medical Corps, United States Navy. Several articles have appeared during the past few months on the venereal-disease problem, and it is believed that the accompanying chart gives a very good picture of the subject, the result of one year's work under the most adverse conditions. The figures are taken from the activities of 1,051 men composing the crew of the U. S. S. Utah during one year, practically all of which time has been spent in ports of Europe and northern Africa, where there is very little if any attempt made by local authorities to institute any proceedings tending to combat the venereal problem. The men are nearly all under 25 years of age, the majority much younger. Prostitution has been unrestricted in all ports with the exception of two, alcoholic beverages comparatively cheap, and both available as soon as the men stepped ashore. Opportunity for wholesome recreation of any kind was not avail able to any extent. Athletics could not be indulged in, owing to the lack of time in ports, lack of suitable grounds, and lack of competition. Moving pictures or other shows were not patronized, because of unfamiliarity with the language, except in English ports. Sight-seeing was the principal amusement, but the novelty of that soon wore off, except for a small minority, and that minority are not in need of prophylaxis of any kind, as they do not expose themselves; for the vast majority there remained only the cafe and dance hall. Every method available was used to combat the problem. The men have been given frequent talks on the subject. Literature on the subject has been liberally distributed. Sight-seeing trips have been arranged in nearly every port, athletics whenever possible, moving pictures on board ship when available, and medical prophy laxis was provided. No. 4. 725 DIVISION OF PREVENTIVE MEDICINE. Naturally the medical prophylaxis has been the most important, as under the existing conditions there have been a large number of exposures. In practically every port a prophylactic station has been established ashore, located as accessible as possible. The hos pital corpsmen go ashore with the first patrol, and the station is open until liberty has expired. Each patrol is able to instruct anybody the nearest way to the station. These stations are not utilized as often as they should be; nevertheless a great many men take the trouble to go to them, and it is believed their establishment is a very desirable procedure. The prophylactic station on board ship is the most popular, as it is easier and the man can get his name on the book with the least amount of inconvenience to himself. This station is open at all hours when men are returning from liberty. It is believed that nearly all treatments after six hours are taken for record only, as the men who have developed disease and have not a record of having taken prophylaxis are severely punished. Convenient packets of calomel ointment have been available at all times, which are given to the men free. They have been placed at the gangway without supervision, have been distributed to each liberty party by a hospital corpsman and left in a convenient place in the sick bay. and every effort has been used to educate the men as to their use. However, they are not used as much as they should be. The last six months of the year was not as bad as the first; part of this, I believe, is due to the men themselves. Drunkenness is de creasing, and the men in general are better behaved. This was made more noticeable by a new draft of about a hundred men who recently came from the United States who immediately got into trouble from overindulgence in alcoholic liquors. There have also been a large number infected with venereal disease. There are now about 00 men under treatment for syphilis, and their propaganda among the crew must have some good effect on the rest, at least through the element of fear. It is not believed that, while the number of prophylactic treat ments is very high, it even approximates the truth as to the /number of exposures. In conclusion, it is believed that under any condition, compara tively good or bad, one must use every available method to combat the problem, and that by constant effort we have reduced the inci dence of disease by from 15 to 20 per cent under the existing condi tions from what it would have been had we been indifferent to the 4539—22 12 726 Vol. XT1L DIVISION OF PREVENTIVE MEDICINE. question or ignored it entirely.

The following is quoted from the United States Public Health Engineering Abstracts from an article entitled "Use of fishes for control of mosquitoes in northern fresh waters of the United States." by J. Percy Moore, professor of biology, University of Pennsylvania, temporary investigator, United States Bureau of Fisheries: The author discusses the value as agents for mosquito control of the roach or golden shiner (Abramis crysolencas) , the goldfish {Carassius auratus), the mud minnow (Umbra pygmaea), the com DIVISION OF PREVENTIVE MEDICINE. 727 mon killifish (Fundulus herteroclitus) , the translucent killifish (Fundulus diaphamus) , the common top minnow of the South (Gam- busia affinia), the blue spotted sunfishes (Enneacanthus glorioms and E. obesus), the long-eared sunfish (Lepomis auritus), and the common sunfish (Eupomotis gibboms). The geographical distribu tion of the species discussed is given in the report, and it is shown that all of them occur, either generally or in some parts of the malarious districts of the South. The results of the investigation, therefore, are probably in part applicable also in the South. Methods of investigation. —The investigations were carried on dur ing the three summers, 1918, 1919, and 1920, principally in Philadel phia and Delaware Counties, Pa., and Palisades Interstate Park, N. Y., but observations and minor experiments were also conducted at other points in Pennsylvania and New York and in Maryland, Delaware, and New Jersey. The plan of procedure consisted in pre liminary examinations of many ponds, swamps, and streams, dur ing which collections of the fauna and flora and ecological data were made. Thereafter certain waters, chiefly small ponds, were selected for detailed study. These waters, as far as possible, were visited at weekly or fortnightly intervals, and usually during the visits fish and other organisms were collected. The fish taken were at once dropped into 4 per cent formaldehyde to stop digestion of foods in their stomachs. The density of mosquito breeding was de termined in the usual way, i. e., by taking water samples with a dipper and counting immature mosquitoes and egg boats. Adult mosquitoes also were collected. Numerous experiments were tried by modifying conditions in such a manner that fish were admitted to places from which they had been absent previously and vice versa, and the actual transplanting of certain species to small ponds and pools was practiced to a limited extent. The conclusions arrived at concerning the various species studied were based upon their obser vations and experiments and upon examinations made of stomachs of fishes preserved during the inspections of the waters. Conclusions. —The conclusions with respect to each species studied are as follows : (a) The roach or golden shiner does not push its way into the "very shallow plant-grown waters where mosquitoes breed." and the investigations, although not conclusive, indicate that this fish has been much overrated as a mosquito destroyer. (&) The goldfish has a very restricted value and is useful only in containers or small waters where foods other than wiggle tails are scarce. (c) The mud minnow consumes mosquito larva?, but its chief deficiency appears to the author to be in numbers, i. e., it usually does not appear to become numerous enough to furnish complete con 728 DIVISION OF PREVENTIVE MEDICINE. Vol. XVII. trol, but since the fish is very hardy he recommends experiments in the direction of artificially propagating this fish. Of 50 stomachs examined, 22 were found to contain mosquito larvae, constituting about 4 per cent of the total contents. (d) Concerning the common killifish, the author says, " The value of this species in limiting the numbers of the salt-marsh mosquitoes is thoroughly established and attested by scores of antimosquito' workers in New Jersey, New York, and Connecticut." (e) The translucent killifish was found to feed to some extent on mosquito larvse, and the author recommends it in preference to the common killifish for muddy ponds and sluggish streams. (/) Gambusia, although not occurring naturally in the area in which the experiments were conducted, was introduced. It did not survive the winter in ponds in the vicinity of Philadelphia where it was planted, but it was found that this minnow can be used to a lim ited extent by carrying a brood stock through the winter in a green house or other suitable place for release the following spring. These fish, under favorable conditions, increase with " astounding rapidity," and mosquito breeding may be controlled by this method in small ponds. (g) " Enough is known of the blue-spotted sunfishes to recommend placing them on the list of species for stocking plant-grown ponds and streams," is the author's conclusion concerning these handsome fish. (h) Insufficient detailed attention was given to the long-eared sun- fish to determine its exact value, but the author thinks it probable that the young, at least, may be of value. (i) The common sunfish was found to be the most valuable of all the sunfishes, the young being particularly effective because they are the ones that visit the extreme margins of the ponds. Stomachs of 224 examples, the majority under 80 millimeters in length were exam ined and " mosquitoes in all stages " constituted 9 per cent of the food present. The author says that it is undoubtedly an important antimosquito agent, and he believes it to be very nearly equal to Gambusia. In my own work in the South I have not found it any thing like equal to Gambusia, and numerous times I have found it necessary to introduce Gambusia into ponds already populated by this sunfish and by the bream or blue-gill sunfish. As a general conclusion the author makes the following statement : " The relatively small number of mosquitoes produced by such waters (ponds, lakes, and sluggish streams under natural conditions) result from this influence. Indeed, it may safely be said that were these fish suddenly wiped out mosquitoes would immediately and generally become intolerable nuisance." This is in entire accord with the statement made by me in a number of public lectures and elsewhere. No. 4. 729 DIVISION OF PREVENTIVE MEDICINE. viz, that several large, prosperous cities in the South never would have been built had it not been for the check on mosquito production prov ided by fish, chiefly top minnows. NOTES FROM THE MARINE BARRACKS, QUANTICO, VA. The health of the command has been excellent, notwithstanding the severe strain to which the men were subjected during the Gettys burg maneuvers. Malaria was more prevalent in July than during the previous month, but this can be accounted for to some extent because of the fact that the personnel was rapidly increased in prep aration for the maneuvers; men being drawn from various posts and from detachments arriving from the Tropics to fill up the organiza tions going on the maneuvers. The majority of these cases of malaria were of tropical origin. Venereal disease, especially gonococcus infection, showed a slight increase over last month. This probably was due to the opportunity of exposure of the men who went on the hike to Gettysburg. .1/ osquitoes. —A great many more mosquitoes are present this year than in previous years. This is due to the fact that practically the entire command was in preparation and on the maneuvers to Gettys burg during the latter part of June and the early part of July, leaving no labor available for mosquito-prevention work, and as a result the work stopped entirely. Brush was allowed to grow up in the ravines, the drainage ditches which had all been gone over and put in condition earlier in the season were filled up, and the water was blocked off in most of the laterals. Culicinse larvse were found to be breeding in great numbers in all of them. The personnel of the medical battalion was immediately set to work cutting down brush, opening and oiling the ditches in the confines of the camp and in adjacent territory. The larger creeks, Quantico, Little Creek, and Chappawamsic were given two treatments of arsenic and dust, 1 part to 100, but it is too early as yet to determine the efficacy of this process. HOTES FROM THE UNITED STATES NAVAL AIR STATION, PENSACOLA, FLA. During the latter part of July an epidemic of gingivitis occurred, which was first discovered by the dental officer, among the marines. The marine command was examined and about 20 per cent of the per sonnel were found infected. A large fusiform bacillus and a deli cate spirillum, similar to those found in Vincent's angina, were found to be the cause of the epidemic. No amo-ha1 have been found in the p3rorrheal cases. 730 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. The rather prevalent use of common drinking cups evidently favors the spread of gingivitis. The medical officer again recom mends that drinking fountains of the bubbling spring type be in stalled in buildings where a considerable number of men are quartered; this is also very desirable for the buildings where the civilian employees work. NOTES FROM THE UNITED STATES NAVAL ACADEMY, ANNAPOLIS. MD. The sanitary condition of the Reina Mercedes and the Cumberland was excellent during the month of July. A special antivenereal campaign, including lectures on morale and venereal prophylaxis, distribution of literature, and instruction con cerning the use of the new collapsible venereal prophylactic tubes, was conducted among the mess attendants attached to these two ships. It is interesting to note that among the men who used 64 prophylactic tubes within six hours after the time of exposure no cases of venereal disease occurred, whereas among the 9 men who took silvol prophylactic treatments six hours or more after exposure 3 developed gonorrhoea, 1 chancroid, and 2 syphilis.

Subject: Arsphenainine and neoaispheuamine. 1. The following letter of Hear Admiral E. K. Stitt, Medical Corps, I'nited States Navy, is approved by the bureau and published for the information of the medical officers of the United States naval service: "July 7, 1920. "To: Bureau of Medicine and Surgery. " Subject : Recommendation that neoarsphenamine be substituted for arsphenamine in connection with use on board ships and at certain sta tions of the Navy. " 1. I would recommend thai the use of ;irsphcnamine be discontinued on board ships of the Navy and in its place to substitute neoarsphenamine. This same recommendation would apply to stations and smaller hospitals. "2. Iu the larger hospitals, where facilities for the administration of arsphenainine are satisfactory, the choice between arsphenamine and neoarsphenamine should be left to the discretion of the commanding officer. "3. This recommendation is made for the following reasons: "(a) In discussing fully this matter with the director of the hygienic laboratory he is of the opinion that most of the accidents attending the use of arsphenamine linve been connected with errors in technic. In view of the simplicity of technic when using neoarsphenamine, many untoward results would be eliminated. "(b) In the clinic of the Brady Institute, neoarsphenamine is used ex clusively, and Doctor Young and his associates are unable to note any lessened therapeutic efficiency with this drug than when arsphenamine is used. " E. R. Stitt." 2. The commanding officers of the United States naval medical supply depots will be instructed to include neoarsphenamine on the supply table and requisitions on Form 4 will be filled at the supply depots. 3. Requisitions from the larger hospitals will be approved for either arsphenamine or neoarsphenamine as the commanding officers prefer, but it is recommended that commanding officers of the larger hospitals continue to requisition arsphenamine until the present supply is exhausted. W. C. Braisted. 2. In connection with the bureau's circular letter quoted above, it appears that the medical departments of some ships are still carrying both arsphe namine and neoarsphenamine. It has come to the attention of the bureau recently that an instance of the accidental use of arsphenamine occurred under an impression on the part of the medical officer that he was using neoarsphena mine, with serious results. This confusion of one variety of arsphenamine with the other has in some instances been enhanced by the similarity of labels 734 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. on the containers, but steps have been taken by the manufacturers to differenti ate more carefully the two varieties by distinctive labels. 3. Since the instructions contained in the bureau's circular letter No. 44-1920 contemplated that only one variety of arsphenamine should be maintained in stock on ships, stations, and smaller hospitals in order to avoid the difficul ties referred to in paragraph 2, it is directed that all arsphenamine now in stock in the medical stores of all ships, stations, and smaller hospitals be immediately returned to the nearest naval medical supply depot. It is further directed that in medical departments of hospitals where both varieties of arsphenamine are retained in stock care be taken to differentiate sufficiently the two varieties so that no confusion can result in selecting the appropriate technic for the variety intended to be used. 4. No. 31, volume 37, Public Health Reports, dated August 4, 1922, contains " standard instructions for the preparation and intravenous administration of arsphenamine and neoarsphenamine for use by the Medical Departments of the Army, of the Navy, and of the Veterans' Bureau, and by the Public Health Service." These instructions should be followed. E. R. Stitt. Circular letter, serial No. 209-1922. DCC: SMS 128586(84). Department of the Navy, Bureau of Medicine and Surgery, Washington, D.

That no person admitted into the mili tary or naval forces of the United States after six months from the passage of this amendatory act shall be entitled to the compensation or any other benefits or privileges provided under the provisions of Article III of the war risk insurance act, as amended." The Judge Advocate General (26510-1481) commenting on this provision states: "In view of the foregoing, you are advised that as the law now stands enlisted men entering the service either in a first enlistment or through a reenlistment since February 9, 1922, do not come within the purview of the Veterans' Bureau act or within the provisions of the pension laws unless their rights under said pension laws accrued prior to October 6, 1917." 3. In view of the above-quoted law and decision of the Judge Advocate Gen eral, this bureau feels that it is incumbent upon it to retain for a reasonable period those members of the personnel who enlisted after February 9, 1922. especially until Congress passes some measures for their relief. This applies particularly to cases of tuberculosis and other diseases where the patient will require institutional treatment if he were discharged. 4. It is requested that persons so retained be surveyed after each three months and that the board of medical survey state the necessity for their retention. If the person surveyed desires to be discharged from the service, lie should be informed of his status and that fact stated on the medical survey form recommending his discharge from the service. In the case of persons l-eenlisting after February 9. 1922, who are surveyed for disease or disability No. 4. 735 DIVISION OF PREVENTIVE MEDICINE. occurring after their reenlistment, the survey board should state the relation, if any. between the present disability and their service subsequent to October 6, 1917. 5. The bureau does not desire the retention of persons whose disability is discovered soon after enlistment, if " not in line of duty," and who are able to care for themselves if discharged. 6. Patients who enlisted prior to February 9, 1922, should be surveyed, recommended for discharge from the service, and retnlneri as supernumeraries until taken up by the Veterans' Bureau. F. L.

(c) Stimulating in adjacent community welfare activities which can be bene ficial to the patients. During the World War and subsequent demobilization the Red Cross activi ties at naval stations and bases were very helpful to the Navy 'and were greatly appreciated. At the present time Red Cross personnel under the direc tion of a field director is maintained at eacli naval station and large marine post where valuable services, especially in connnection with the home service conditions and contact between an enlisted man and his family, etc., are rendered. The social service department of the Red Cross in relation to Veterans' Bureau patients in naval hospitals has to do with— <<*) Securing social histories and other significant data for use of tuber culosis specialists and psychiatrists. 738 Vol. XVII. DIVISION OF PREVENTIVE MEDICINE. (b) Securing reports on home conditions for help of physicians in deciding whether or not to discharge a patient to his home. (c) Correspondence with home communities to adjust home situations, thereby making it possible for patients to remain in hospitals. This sometimes involves financial aid to families. (d) Arranging through local communities for men who return home to have proper care and assistance in adjusting themselves to civilian life. (e) The Red Cross maintains an information service which deals with— (1) Communicating with family doctors and others to assist in securing affidavits necessary to substantiate Government claims. (2) Information to families regarding patients' personal and family affairs when advised to do so by the commanding officer. (3) Furnishing information to patients regarding Government legislation. (4) Furnishing information regarding Government insurance. (f) The Red Cross also assists in the matter of following up Veterans' Bureau patients who leave the hospitals A. W. O. L. or against advice to see that they return, or if leaving against advice that they are placed under proper supervision in a home community. The Red Cross maintains Red Cross convalescent houses at each of the large naval hospitals where patients may avail themselves of the opportunity to read, play such games as their physical conditions permit, write letters, etc. The Red Cross has accomplished a great deal in filing with the proper offices information and data necessary for Veterans' Bureau patients to receive com pensation from the bureau. There are at present nearly 800 Veterans' Bureau patients in naval hospitals, a large number of whose claims for compensation have not been settled. Through the investigations by the Red Cross and data furnished settlement of these claims is greatly expedited. The Red Cross Society maintains in practically all of the large naval hos pitals personnel to instruct the patients in occupational therapy. This con sists of bead work, basketry, weaving, metal work, toy making, etc. (These departments are practically self-supporting.) One of the most commendable works of the Red Cross for naval, marine, and Veterans' Bureau patients in naval hospitals is to keep their families ad vised as to their condition, and to help, often financially, to make arrangements for parents to visit their sons whose conditions are critical.

Subscriptions should be sent to Superintendent of Documents, KT LYON AND NECESSARY WORK UNDER TAKEN TO FIT IT FOR MODKUN SANATORIUM PURPOSES FROM 1906 TO 1922. The first Navy detachment ordered to Fort Lyon arrived there on November 17, 1906, and was composed of Surg. T. A. BerryhiU, Surg. James G. Field, Civil Engineer A. L. Parsons, and Pharmacist Phillips. When this party arrived they were confronted with a sorry sight. The buildings were dilapidated and falling to pieces. There was not a sound roof nor even a part of the old buildings which could safely be used for a temporary shelter. A great deal of the damage was the result of natural deterioration, but the Colorado blizzards, Band, and rainstorms had been assisted in their work of destruction by human agencies. The buildings had been systematically looted and gutted. Doors, windows, and even structural timbers had been carried away, and it is said that this material may still be found in many of the old ranch buildings in the vicinity. Cattle and horses roamed about freely on the grounds and in the houses, rattlesnakes No. a. WIEBEB —NAVAL HOSPITAL, FORT LYON. were encountered not infrequently, and signs of destruction were everywhere. , In view of these conditions, temporary office rooms were secured in the courthouse of Las Animas. On November 20 the naval party was joined by Civil Engineer W. R. Murphy and two assistants, both civilians, and Paymaster Ammen, U. S. Navy. In January, 1907, Surg. B. L. Wright arrived as the first patient. He was immediately placed on a duty status. At the fort, naturally, the first work started was the establishment of a temporary tent camp with sanitary facilities. Then a large labor force was employed for the clearing away of rubbish and for making temporary repairs to dangerous roofs and walls of build ings; others were employed in the construction of a more permanent camp of rubberoid sheds and in the erection of tent quarters for duty personnel and patients. The first plan of the reservation was completed in December, 1906, and is still on file in the public works office. The duty personnel moved to the fort into tents during the middle of February, 1907. On February 25, 30 bundles of hospital tents were received for the accommodation of patients, who, however, it seems, did not arrive in any large numbers until about September 16, 1907, at which date 24 arrived from Fort Bayard. Of the 24 buildings found on the reservation about 10 were torn down, among these being the barracks at the east of the parade ground and a number of buildings north of the officers' row. The others were repaired. These included the administration building, two west wards (formerly used as barracks), the barn, the south storehouse, the officers' quarters, ward C, the operating section of the men's infirmary, and the " Kit Carson house." which is used at present as a schoolhouse. The reservation was devoid of trees and was covered with weeds; roads did not exist; tumbleweed predominated everywhere. The water supply was derived from shallow- wells. The work of remodeling the buildings and of const ru: ting sewers, digging wells, constructing a heating system and a power plant was mostly accomplished by contract from plans prepared at the hospi tal and at the Bureau of Yards and Docks. While this work was progressing, plans were prepared for new necessary buildings, viz : Leantos 4, 5, 6, 7; east subsistence building: bakery: pharmacists' quarters 304 to 309; civilian quarters 321, 322, 323, 324, and 370; bowling alley; west subsistence building (center wing); laundry: north storehouse, officers' infirmary and cottages; wards E. F, and G of the men's infirmary; commissary store; disinfecting building: pump house; and reservoir at the main gate. A 100.000-gallon fresh-water pressure tank was completed in June, 1908. Until that 748 Vol. XVII. WIEBER —NAVAL HOSPITAL, FORI LYON. time the water was supplied to the houses in barrels. The building period for these .structures, which were also erected by contract, ex tended over several years. Simultaneously with the above construc tion a number of small farm sheds, shops, and storehouses were built; in addition, roads and walks were laid, many trees were planted, lawns were established, and farm and irrigation systems were devel oped and put in operation. By 1911 the hospital was a well-organized institution of approximately 200-bed capacity. Civil Engineer Par sons was then detached and no public works officer was attached to the fort until the summer of 1919. Between 1911 and 1917 there were no public works activities, no new construction, and few im portant changes were authorized. As a result of the lack of avail able funds the buildings and grounds began to appear ill kept and shabby. Beginning about 1917 new construction again became active. The commanding officer was authorized to purchase a dairy herd, which required a dairy barn and sheds. These, as well as four s los and a house for the dairymen, were contructed by station labor. The area of the reservation, which when turned over to the Navy consisted of only about 500 acres of land, was more than doubled by the pur chase of the West Farm, and work was begun there on sheds, corrals, and also on the irrigation systems. As the year advanced a great in- flux of patients—in consequence of the great expansion of the naval l'orces—took place, and th s demanded increased accommodations for patients and duty personnel. Wards A, B, D, H, I, J and Lean-tos 1, 2, 3, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 18 were built by station labor. The construction of a nurses' home was also authorized; 36 ready-cut cottages were obtained for speedy erection. Increase of quarters for attendants, mess halls, and storehouses were needed; the heating, lighting, and power-plant utilities soon became overtaxed and demanded expansion. By 1919 the hospital was buzzing with construction activity, the work being accomplished by the sta tion force. At about this time the need of technical supervision for coordination and organization of this work became apparent; the old buildings had become dilapidated; grounds and roads needed attention. During the summer of 1919 the Bureau of Med cine and Surgery took cognizance of these conditions, reorganized the admin istrative personnel, and ordered a public-works officer to Fort Lyon to assist the commanding officer in his work. Assistant Civil En gineer Andrew S. Bisset was detailed for this work. A public-works organization of draftsmen, inspectors, and engi neers was established and surveys and inspections were begun. Much of the work done between 1917 and 1919 had been done, as a result of the lack of proper technical supervision, in a haphazard sort of a way. and water, heat, and light service had been extended without Xo. 5. 749 WIEBER NAVAL HOSPITAL, FORT LYON. plan record. This made a complete resurvey of the reservation neces sary before revision and coordination could t>e attempted. In the meanwhile a definite program of overhaul and repair to the build ings was started. This work included new slate roofs on the princi pal buildings, new floors, new electric lighting, plumbing, plastering, and painting. The mess halls and kitchens of the subsistence build ings were improved with tile wainscot and floors, and new equipment was installed. The buildings which were under construction were completed with certain changes, a number of others which had been completed were altered to improve the fire protection, lighting, and utility. Extensive new construction and additions, to round out the hospi tal as a 700-bed unit, were then undertaken. This work was done by contract and station labor, in accordance with plans prepared by the public- works officer and approved by the Bureau of Yards and Docks. The projects included power-plant improvements, new sewers, exten sion and revision of water mains, new water-storage tank of 400,000- gallon capacity and a 200,000-gallon pressure tank, revision and ex tension of light and power lines, concrete pavements and sidewalks, and new heating mains. Among the new structures are the pharma cists' quarters 310 and 311, four sets of quarters for medical officers, the nurses' infirmary, the main gate and guardhouse, a new Ward K for the men's infirmary, the marine barracks, and a number of civil ian quarters on the northeast road and at the West Farm. A Red Cross house was built and paid for by the American Red Cross. Additions were constructed to the east subsistence building, bakery, laundry, cold-storage building, garage, and to 18 sets of quarters. Eleven ready-cut cottages were moved from around the administra tion building to the northeast road- and converted into quarters for chief petty officers and for patients. The farm buildings, particu larly the dairy barn, were greatly improved, and the piggery was moved from the vicinity *f the hospital to the West Farm. The refrigerating capacity was enlarged from the original 8 tons refrig eration and 2 tons ice-making capacity in 24 hours to a refrigerating capacity of 55 tons and an ice-making capacity of 19 to 20 tons (in 24 hours) . The boiler power was increased from a capacity of 400 horse power to one of 930 horsepower. This is furnished by six boilers. The original electric plant consisted of two 20-kilowatt generators: this was gradually increased to one of a total of 318 kilowatts. An abundance of surface water for flushing, fire protection, irri gation, and sprinkling purposes is supplied by four electrically op erated pumps. The water is taken from a swamp at the northeast of the station. A pumping test in 1917, kept up for 40 days, which drew 1,500 gallons per minute, did not appreciably affect this sup 750 WIKBKR XAVAL HOSPITAL, FORT LYON. Vol. XVII. ply. To this was added a new steam-driven pump having a capacity of 750 gallons per minute. This supplies the flushing system. The drinking water is supplied by three artesian wells from a depth of about 300 feet and by five other wells from a depth of about 100 feet. These furnish about 300,000 gallons in 24 hours. The water is potable; it has a slightly alkaline taste, but is not injurious in any way. The fresh-water storage capacity is 700,000 gallons. For fire protection there exist nine fire-alarm boxes, with sufficient hydrants to protect the entire reservation. Of all this repair or expansion work in connection with the power house, only the 400,000-gallon storage tank, the 200.000-galIon pres sure tank, and the power-house chimney (having a height of 155 feet) were erected by contract work: everything else was done by station labor. The last large, project (which is now Hearing completion) is the new steam and heat distributing system for the northern part of the reservation buildings. This supplies heat to 28 new buildings and revises the heat supply to 21 additional buildings. There are about 180 buildings on the reservation ; the population during Navy days numbered about 1,000 persons, including patients. The cost of the work accomplished under the direction of the pub lic works' officers from 1907 to 1911 is approximately $565,000: of that completed from 1917 to 1922, is $1,850,000. The approximate valuation of the hospital property is as follows (September 28, 1921) : Buildings and structures $2, 200. 000 Land 120.000 Pavements, roads, walks, lawn, sewers, pipe lines outside of build ings - 580,000' Power-plant equipment and mechanical equipment, pipaig in build ings and shops, tools.. 3-10,000 Ambulances and garage equipment - 50.000 Farm Implements, live stork, tools, etc «. 40.001' Stores and building material on hand 30,000 Hospital equipment, linen, furniture, instruments, etc 445,000 Mess fear, foods, eul'nnO' supplies. 5.">.000 3. 860.000 PRKSKNT HOSPITAL ACCOMMODATIONS. With the enlargement of the station, naturally the equipment for the accommodation, care, and treatment of patients kept pace. All wards have covered porches, which are 'used by all but the very sick or terminal cases: the wards themselves are heated so that patients during inclement weather could move their beds indoors: at least, they could dress themselves indoors. Toilets, with shower baths supplying cold and hot water, are installed everywhere. So. a. 751 WIEBER —NAVAL HOSPITAL, FORT LYON. There are now five separate mess halls, with complete modern kitchen and dish-washing equipment, viz : One for infirmary patients. One for ambulatory cases. One for duty personnel. One for sick officers. One for sick nurses. There exists an operating room fully equipped and always ready for use; a fully equipped dental department, with two chairs; a dark room for eye, ear, nose, and throat cases; a fully equipped laboratory; an X-ray department, consisting of a waiting room, an operating room, a filing and study room, and a developing room. The X-ray operating room contains, in addition to the table, all the apparatus and equipment necessary for the making of pictures and for fluoroscopic work. This room is entirely in black. The de veloping room is also finished in black and is equipped for the development of large numbers of plates or films of any size. It is also provided with an exhaust system of ventilation, which aids in the drying out of plates and films. It contains lead-lined negative boxes, with running water conveniently arranged, and suitable sinks for the making of developer, fixing solution, and washing chamber. As regards the equipment of the main part of this laboratory, the apparatus consists of a Scheidel Western 8-kilowatt 220-volt 60-cycle alternating-current machine of the standard rotary converter type. This primary plant derives its power from the regular power supply of the station and insures sufficient power and penetration for all routine work, and with the Coolidge system, which is exclusively used here, has been fairly satisfactory. The low-tension or heating system of the Goolidge tube is obtained by a step-down transformer deriving its energy also from the main current supply. In addition to this last-mentioned system there is provided a battery system for the heating of the Coolidge filament, which has been of great use at such times when the fluctuations in the main current supply resulted in difficulty in maintaining a con stant temperature of the tube filament. The table used in the laboratory is the standard Victor universal type. In addition to being provided for the taking of stereoscopic pictures, it is also provided with a 10-microampere self-rectifying radiator Coolidge tube for fluoroscopic work, and may be operated in any position from the horizontal to the vertical position. The high- tension wiring system is of the overhead cable arrangement and is placed 12 feet above the table. Duplitized films are used exclusively for the work in chest and gastrointestinal exposures, and this is reinforced by the use of the 752 Vol. Wll W1KBKH— NAVAL HOSPITAL. FORT LYON. double-intensifying screen. For this part of the work the laboratory- is provided with six Patterson double-intensifying screens. Since 90 per cent of the work done in the. laboratory is that of chest examination it has given rise to a technique which has been found of the most practical application to the roentgenologist and to the patient. Ordinarily the chest examinations are made standing and, to facilitate this part of the work, special arrangement as regards a plate holder or stand has been provided, which permits of the exposure with only one adjustment for the tube. This has been a great saving in time to operator, and saves weak patients the trouble of climbing upon the table. ROUTINE AND SPECIFIC METHODS OF TREATMENT. Fort Lyon must be considered as an ideal spot for sanatorium pur poses in the care of tuberculous diseases. It has an elevation of a little less than 4,000 feet, is about 7 miles distant from the nearest town, the relative humidity is very low. the rainfall very slight, the sky is generally clear, the number of sunshiny days is very great, and the nights are cool and bracing. Through its dairy herd, which it is still developing, it furnishes now the greater portion of the milk supply needed for its patients. By its farm products almost all the feed necessary for its herd is supplied. The waste from the mess halls is in part used for the feed ing of about 300 pigs, which furnish a not inconsiderable part of the pork used in the commissary department. One drawback to Fort Lyon, which, however, it shares with manv other sanatoria in the Kocky Mountain Plateau region, is the prev alence of dust storms in late winter and early spring, before the vegetation has started. These sometimes last for a whole day : gen erally, however, they are of short duration. I have seen the air so thick with dust that it was impossible to see across the parade ground. Such storms, while they last, are of positive harm to patients, inas much as they seem to have a depressing effect on them and increase their cough. The treatment of the patients is based on modern ideas and con sists mainly of good rich food, out-of-door life, observation of rest hours, and heliotherapy. The routine methods followed at Fort Lyon are a- follows: All patients admitted are placed in bed in a receiving ward in the in Hrmary and kept in bed continuously for about two weeks. While there accurate temperature and pulse observations are taken and re corded. A careful physical examination of the chest is made and re corded graphically on chest charts. The urine, feces, and blood are examined ; X-ray plates of the chest are made in every cas« ; an eye. ear. nose, and throat examination; and, finally, a dental examination •No.8. 758 WIBBER NAVAL HOSPITAL, FORT LYON. 4 is made. The blood examination includes a Wassermann and a tu bercle bacillus complement fixation test. The sputum is examined daily until 10 negative findings are recorded, or until one test turns out to be positive. The receiving ward is generally under the charge of one of the older and more experienced and trustworthy as sistants. After all the examinations required on admission have been made and a diagnosis has been arrived at, the case is disposed of by being sent either to a lean-to where ambulatory cases are treated, or, if further infirmary treatment is considered necessary, to one of the re maining 10 wards. This includes cases requiring further observation for the establishment of a diagnosis. Cases considered negative for tuberculosis or any other disease, after a month's observation, before final action, would be examined by a permanent board of survey for final disposition. All febrile cases are assigned to an infirmary ward: likewise all those with marked activity. Rest periods are enforced as follows: Forenoon from 9 to 11 for all definitely tubercular active cases; afternoon from 1 to 3. These two periods are subject to modification by the medical officer in charge of the ward. Only nonfebrile. quiescent, or arrested cases may be detailed for work alM)iit the ward. All cases of tuberculosis sleep out of doors on covered porches, ex cept during very severe weather. The wards proper are well heated : likewise the toilets and bath stalls. For the heliotherapy treatment the graduated system of Rollie-r has been adopted. This line of treatment was started in a systematic- manner during the summer of 1921, and the patients took to it very well. It was begun by a 5 minutes' exposure of both feet to the direct rays of the sun. On the second day 5 minutes were added to the exposure of the feet and o minutes exposure of legs up to the knees was begun. The third day 5 minutes' exposure from knees to hips, 10 minutes from knees to ankles, and 15 minutes for feet was required, etc. After the front had been thus gradually exposed to the sun. the back was similarly treated. The head was protected during the exposure by any sort of device produced by the patient's ingenuity. The object sought was to bring about intense pigmentation of the body without ac tual sunburn and any sign of reaction, such as fever or exhaustion. The slightest sign of such a symptom should cause suspension of the treatment and resumption only after disappearance- of all abnormal reaction. In a febrile case no heliotherapy treatment was instituted. The patients were required to wear bathing trunks and stretched them 754 Vol. XVII WIKBEK NAVA1, HOSIMTAL, FORT LYON. selves out on canvas cots which were placed on concrete aprons in the infirmary courts or on the south side of the lean-tos. The cob were only received during the middle of the past summer and the treatment was in use only for about two months, consequently no expression of opinion as to results can be given. Other forms of specific treatment of tuberculosis formerly used but discontinued were the following two : The treatment by hypodermic injection of sodium morrhuate. which had been first recommended by Sir Leonard Rogers, lieutenant colonel, I. M. S. When this treat ment first become known, a number of the patients at Fort Lyon sent to England to procure the drug and requested that it be used on them. This led to its general use in our patients, and at first it seemed to give promising results. It was given in a <$per cent solu tion in gradually increasing doses, beginning with one- fourth to one- half cubic centimeter of the 3 per cent solution subcutaneous! v. and increasing by 2 to A minims at each injection two to three times a week until a reaction occurred; then after the interval of a week a dose smaller than the one which had produced the reaction was again given. After the subcutaneous dose of 2 cubic centimeters had been reached, intravenous doses, beginning with one-half cubic centi meter, were given and gradually increased as before. In some cases doses up to 4 cubic centimeters were given. In febrile cases the dose- were smaller and increased more gradually. A reaction consisted in a rise of temperature; occasionally a slight hemoptysis occurred No harm seemed to follow such reaction. The patients were very en thusiastic and reported daily improvements. Clinically there seemed to be improvement. In some cases there was an increase of weight: in many cases gastric symptoms subsided ; some febrile cases becanit afebrile. Many reported an increase in expectoration during the first weeks, followed by a decrease of cough and expectoration. After following up these cases for months to a year, the consensu* of opinion was that the improvement of symptoms was not actually due to improvement in physical signs, for the area of activity showed no sign of improvement. No ill effects, on the other hand, followed the use of the drug. The effect of the treatment observed seemed t<> be more psychic than actual. The patient felt that something wa- actually done for him and he felt encouraged. The treatment by medicated sprays was likewise tried for a period and abandoned. The use of calcium chloride in the symptomatic treatment of vari ous complications of tuberculosis met with partial success
