Chapter XII: Part II: , Showing Predominance of Malarial Element . . . . 617 (11)

It is not an uncommon error among men engaged in mental work to suppose that they can, and ought to, take the same amount of exercise which gives good results in those whose occupations involve physical rather than mental effort, or to think that the more exercise they take the more study or writing they are equal to. This is a grave mistake. Expenditure of brain-tissue is not to be repaired by muscular exertion, but by sleep and food, and exercise in the fresh air sufficient to produce appetite and sufficient weariness to ensure restful sleep is all that is necessary. For a time it is true that the student or writer who has a well-developed body can continue to burn the candle at both ends, and win literary honors while also standing high as an athlete; but this surely leads to physiological bankruptcy in the end.

It is to be remembered that good muscular development is not necessarily synonymous with health, and that strength is not a guarantee against disease. And, while it is true that in this, as in most other matters of individual hygiene, each man must to a great extent be a law to {200} himself, and learn by experience what kind of exercise and how much of it he requires, yet the physician can often supply the motive which was wanting, or check undue effort. Exercise for the sake of health and comfort is not an end, but a means; yet if this means can be made to secure to the patient an end agreeable and pleasant in itself, so much the better.

XI. CONTAGION AND DISINFECTION.--By "contagion" we mean the communication of disease from one person to another, either by direct contact or through some medium, such as air, water, etc. It therefore includes "infection," which is now generally used as a synonym for it. The so-called infective diseases of modern German writers (Infections-Krankheiten) include, besides what are commonly termed in English, contagious diseases, the so-called miasmatic diseases.

The characteristic of a contagious disease is its specificity; that is, the disease transmitted is always the same in its essential characteristics. It does not, however, follow that all cases of the disease are equally liable or have the same power to transmit it; in other words, the degree of virulence of the contagiousness is not an essential characteristic. That the same disease sometimes spreads rapidly and is very fatal, and at other times seems hardly to have any contagious properties and is very mild, has long been noticed, and has been attributed to an unknown something called the medical constitution of the place--the constitution médicale of French writers. The true cause is probably very complex, but in some cases, at all events, it seems to be due to difference in the contagion itself. If we suppose this contagion to be a minute organism, it is easy to form a theory as to the cause of these differences, but there is much careful experimental work to be done before we shall have positive knowledge on this point. The results obtained by Pasteur in attenuating the virus of chicken cholera and splenic fever indicate one line which these experiments will take, and the researches of Koch point out another.

The diseases which spread by contagion until they form epidemics are those which have from the earliest times attracted the most general attention, and which have given rise to organized efforts for prevention--_i.e._ to public hygiene.

They are also the diseases which have given rise to the most bitter controversies among medical men as to the means of their propagation and the best methods of prevention. Plague, cholera, yellow fever, and typhus are those with regard to which this difference of opinion has chiefly occurred--one party considering their chief cause to be contagion, or specific germs derived directly or indirectly from the bodies of the sick; the second party declaring that they are due to filth plus an unknown something, which is variously termed epidemic constitution, pandemic wave, Providence, or _x_. The great majority of opinions at present is in favor of the view that they are all contagious, but not all, or always, contagious from person to person--that they spread from infected localities, which localities receive their infection from cases of the disease. The best means of dealing with them under ordinary circumstances are now tolerably well understood, and where these means can be commanded--as, for instance, among troops in time of peace--epidemics of these diseases can be stopped with great precision and promptness by isolation and disinfection.

{201} By "isolation" is meant not only the separation of the sick from the well, but the isolation of the infected locality or water-supply until it has been rendered harmless.

By "disinfection" is meant the destruction of the specific causes of disease, and more especially of the infectious or spreading diseases. A disinfectant is not necessarily an antiseptic or a deodorant, nor are these last necessarily disinfectants. The best practical antiseptic for sanitary purposes is cleanliness; the best disinfectants are heat, bichloride of mercury, sulphate of iron, chloride of zinc, sulphurous acid, chlorine, sunlight, and pure air, and, for yellow fever, cold. With our present very imperfect knowledge of the nature of specific causes of disease which we wish to destroy, we have no means of determining the presence of these causes in or on an article of clothing or of furniture, or in a room or other locality, except by the production of their specific effects on man or by inductive reasoning; in other words, we can only say that it is more or less probable that such causes are present. This makes it necessary, or at least expedient, to employ disinfectants in many cases where the presence of such causes is doubtful. The practical difficulties are, first, to bring the disinfecting agent into such relation with the causes of disease that it can act upon them, and act upon all of them; second, to avoid unnecessary destruction or injury of things which should be preserved. The majority of the causes of disease upon which we wish to act by disinfectants are probably minute particles of solid or semi-solid matter which are living, and may be conveniently designated by the word "_germs_." In the presence of moisture the destruction of the vitality of these germs can be effected with comparative ease and rapidity, but when they have become dried, or, as in the case of the bacilli, are in the form of spores, it is a more difficult matter.

To illustrate the methods to be pursued and the precautions to be taken, let us suppose the physician to be called on for directions as to the management of a case of scarlatina, the object being to prevent its spread. The first thing to be done is to get the patient in a room by himself, and to leave nothing in this room which is not necessary. Remove the carpet, curtains, and all stuffed or upholstered furniture. Let the nursing be done, as far as possible, by one person only, and do not allow others, and especially children, to enter the room, no matter if they have had the disease. The danger of contagion depends upon particles coming from the skin and mucous membranes. All excreta, and more especially the sputa or discharges from the mouth or nose, are to be treated as dangerous. The excreta should be received in vessels containing a solution of sulphate of iron, one and a half pounds to the gallon. All clothing, towels, bed-linen, handkerchiefs, napkins, etc. should be placed in a solution composed of four ounces of sulphate of zinc and two ounces of common salt to the gallon of water as soon as they are not needed for further use. Especial care should be taken that none of these articles are removed from the room while dry, and while they are in the room, and before they have been moistened, they should not be shaken or disturbed more than is absolutely necessary. If for any reason the zinc solution above referred to is not at hand--which should very rarely be the case--the clothing, etc. should be placed in a bucket, tub, or boiler containing enough scalding water to entirely cover them, and be removed {202} from the room in this vessel. All such articles should be boiled at least one hour.

No sweeping or dusting in the ordinary way is to be done in the room; dust and dirt are to be removed by damp cloths, which are to be treated like the bedding and clothing. The great object is to prevent as far as possible the production of dust in the atmosphere of the room. The entire body of the patient, including head, face, and limbs, should be kept thoroughly anointed with camphorated oil, vaseline, or some similar substance, and especial care should be taken in this respect during the period of convalescence so long as any roughness or desquamation of the skin continues. No toys or books which it is desired to preserve should be allowed to remain in the room, and under no circumstances should books or toys be borrowed to amuse the child if they are to be returned. The best way to disinfect such articles is to burn them in the room.

When the patient is fully convalescent and all desquamation has ceased, cleanse him thoroughly with a warm bath and soap for four successive days. If at the end of that time no roughness of the skin remains, he may be dressed in clean clothes and taken from the room, for he is no longer a source of danger. The room itself and the furniture are then to be thoroughly cleansed and disinfected. The ceiling and walls, if of ordinary hard finish, are to be scraped and whitewashed. All woodwork should be rubbed with damp cloths and the floor well scrubbed. Care should be taken to remove all dust from the ledges over windows and doors. All the cloths used in this cleansing process are to be burned.

If these directions have been carefully carried out, there is no need for further disinfection. But if upholstered furniture has been allowed to remain in the room, or other articles which cannot be burned or scrubbed or soaked in the zinc solution, it may be desirable to attempt to disinfect the whole room and its contents by means of chlorine or sulphurous acid gases. Of these, sulphurous acid gas is the cheapest, and upon the whole the best, but it must be used in large quantity, and for a longer time than is customary, if it is to be relied upon. For this purpose all openings into the room should be closed, and pillows, mattrasses, upholstered furniture, and articles which cannot be treated with the zinc solution should be opened, so that they may be exposed throughout to the fumes. The sulphur should be burned in an iron pan or pot, placed in a tub containing water or upon a large surface of sand. About 18 ounces of roll sulphur should be used to each 1000 cubic feet of space, and after twenty-four hours 12 ounces more should be burned and the room be then closed for twenty-four hours longer, after which it may be opened and aired. In case of death the body should at once be wrapped in a sheet thoroughly soaked with the chloride of zinc solution, and either be placed in an air-tight coffin at once or be buried without delay. The funeral should be strictly private, and the sheet referred to should not be disturbed or the body exposed to view.

The cases most liable to spread the disease are those in which the attack is very light and the child is not confined to its bed. It is desirable that children in a house in which there are cases of scarlet fever should not be allowed to attend school or mingle with other children who have not had the disease.

With regard to disinfectants, it may be well to note that none of the {203} various patent disinfectants are superior to bichloride of mercury, chloride of zinc, sulphate of iron, chlorine, and sulphurous acid; very few are equal to them, and none cost so little. As a gaseous disinfectant for rooms, etc. chlorine is superior to sulphurous acid, but it has the disadvantage of injuring metals, is not so easily applied, and is more costly. It will destroy the vitality of the spores of the bacilli more rapidly and certainly than sulphurous acid, which last, to make sure work, must be exhibited for a much longer period than is customary. I should not feel confident as to the thorough disinfection by sulphurous acid of the hold of an infected ship unless the fumes had been applied for sixty hours. Carbolic acid as ordinarily used is an antiseptic rather than a disinfectant. Its vapor in a sick room is absolutely useless. When applied in strong solution it is effective, for a time at least, but as thus used it is expensive, its odor is unpleasant to many, and masks the odors from putrefying substances and excreta, etc., thus preventing the warning which these odors would give. Its use is in many cases very much like removing the rattle from the rattlesnake.

The suggestions made above for limiting the spread of scarlatina from a case to be treated in the residence of the patient apply--with certain modifications for each form of disease, which will readily suggest themselves to the physician--to all the affections due to portable contagia.

Among the poorer classes, however, it will often be found impossible to obtain the separate room and service and the constant intelligent care which are necessary to ensure the desired result; and in such a case the patient should be removed to a hospital, for his own sake as well as for that of the community. The utility of small hospitals for infectious diseases is by no means generally understood, and very few of our small cities and towns are provided with anything of the sort. If the subject is urged on the authorities of a place, the reply will be that it is an unnecessary expense, that the people would not go to it, and that such an institution is in itself a source of danger. The facts are, that such a hospital costs very little, and is the cheapest insurance against epidemics which a town can have; if it is kept clean and comfortable, the people will use it freely, and if properly managed it does not offer the slightest danger to the vicinity. This question will be further discussed in the last section of this paper.

The principles of isolation as applied to a single case as indicated above may also be applied to infected localities in case of epidemics. When taken in time, all diseases which depend upon particulate contagia for their origin can be stamped out by isolation and disinfection. Unfortunately, to effect this promptly and successfully requires money, labor, and the co-operation of the well in the vicinity; which last it is usually impossible to obtain voluntarily or to compel sufficiently to secure the desired results. A question which sometimes arises in case of epidemics, and with regard to the necessity for which physicians will be consulted, relates to the closure of the public schools. It is certain that the assemblage of children in schools exerts a powerful influence on the spread of such diseases as scarlet fever, diphtheria, and whooping cough. On the other hand, the closure of the schools infringes upon the rights of a large number of the community, and if long continued, as it sometimes must be to be really efficacious, inflicts upon them {204} a permanent loss. It is, moreover, a confession on the part of the authorities of inability to induce or compel what must always be a comparatively small part of the community to take the proper precautions. It is never justifiable to close schools on account of small-pox, and where there is a competent health authority supported by the influence of the medical profession, it must be a very exceptional set of circumstances which justifies their closure for diphtheria or scarlatina.

It is not deemed expedient here to discuss the vexed question of quarantine. It is more important against yellow fever than any other disease, because every day of delay of the entrance of the disease which it secures lessens largely the subsequent mortality, since the duration of the disease is limited by frost. This is not the case with cholera, and the mere keeping this disease out of a place for a few weeks does not diminish its ravages when it has once gained an entrance. To rely altogether on quarantine, either maritime or inland, to keep yellow fever, cholera, or any other disease out of this country is a far greater mistake than to neglect it altogether. The practical way to isolate and quarantine is to get as close to the affected spot as possible. Precautions at Havana for yellow fever, or at Hamburg for cholera, are far more useful to the United States than the same amount of work at our own ports can possibly be; really good work in this direction must be not only national, but international.

XII. MENTAL CAUSES OF DISEASE.--A man may give too much attention to his health and the means for its preservation, and the doing so is both a sign and a cause of disease--probably oftener the former than the latter, except in cases of psychological epidemics. The power of expectant attention, especially if accompanied by belief or fear, to produce derangement of function in the nervous system, and through this to affect the circulatory and digestive systems, is well known to medical men. The effects of an undue amount of brain-work, and especially of the anxiety and worry which often accompany this when it is specially directed to the acquiring of wealth, fame, or power, are also familiar to physicians in our large cities. The analogies between mental and physical exertion are close in some respects, and especially as to the effects of over-exertion in a limited time under the influence of excitement.

The danger from simple mental work, such as study, when there is no excitement from a contest, is small, and depends mainly on lack of physical exercise and consequent disorder of the digestive organs. The risk of producing what Fothergill calls "physiological bankruptcy" is greatest in the youth studying for a prize, the speculator, the man who feels responsibility which he knows he probably cannot meet. The danger of injury from overwork under excitement is a very real one in many of our schools, and, while the evil results are most apparent in girls of the middle and upper classes, the boys and the young men also suffer. The system of pass examinations, in which the standing of the pupil is to be determined, not from the average results of his daily recitations, but from a single examination at the end of the year, produces the greatest risks to health; and this is especially the case where the ambition and pride of the children are stimulated by competition for prizes, medals, etc. Such systems of grading by a single final examination should not be used in ordinary schools, and for some pupils there will always be a risk to health connected with them even when they are of age. No doubt the stimulus of {205} competition is useful with the majority of children as well as of adults, but with some of them it is pretty sure to go too far.

The symptoms produced by undue mental strain are familiar to all physicians, and there is usually little difficulty in tracing the effect to the cause when attention has been directed to the matter; in fact, the patient himself usually knows very well the cause of his troubles. The remedy is, of course, rest--but that does not mean idleness. In speaking of occupation, allusion has been made to the fact that the physician must at times advise his patient as to the adoption of some pursuit, and in cases of this kind such advice is also useful.

The effects of mental strain are often mingled with, and aggravated by, those of stimulants which have been used to spur the flagging energies. Alcohol, tobacco, opium, or coffee used in this way finally increase the very discomforts which at first they relieved.

II. Personal Hygiene in its Relations to the Practice of Medicine.

In the preceding section have been indicated briefly some of the principal causes of disease and the methods for their investigation or removal. We have now to consider some of the practical applications which may be made of the laws of etiology and prevention of disease in the treatment of the sick. While the removal of the cause of illness by no means always effects a cure, yet the importance of a knowledge of this cause as an aid to diagnosis, prognosis, and therapeutics is so evident as to require no proof.

To discuss with anything like completeness the practical applications of what would be commonly considered as hygienic rules in the treatment of disease would be to write a treatise on nursing, and would also include a large part of the practice of medicine, for regimen is the more important half of practical therapeutics. The hygienic requirements peculiar to each disease will be pointed out by the writers upon special subjects, and I shall only venture upon one or two general remarks in addition to the hints already given in speaking of the several causes.

In the acute stages of disease the sensations--or, if the term be preferred, the instincts--of the patient are usually the best guide to his regimen so far as they go. In most cases he desires quiet, shade, but not absolute darkness, and little or no food, although there is often a craving for drinks, especially of a cooling character. In the specific fevers which have a tolerably definite period and course it is important to keep up the nourishment even during the period of anorexia, in order to provide against the debility which is to follow. This nourishment is best given in the form of drink, and very frequently fresh milk is the type of what is required. The old notion that whatever a sick man desired must be hurtful, and therefore that the fever patient must be kept hot and refused cool water, has now almost entirely passed away.

In convalescence from acute disease and in many chronic cases, the sensations of the patient are not to be trusted as a guide in the choice of food. In such diseases as yellow fever and typhoid fever to allow the convalescent to follow the dictates of his appetite is to run great risk of a fatal result. In other cases the patient really has no wish in the matter, but it {206} will often be found that one who can think of nothing which he desires to eat, and who will even refuse a dish which he has requested and been thinking about, will eat with enjoyment some unexpected dainty when presented at the right moment and properly served as a skilled nurse knows how to do. The manner of serving the food, independent of its cooking, is not a matter of such small importance that the physician can afford to overlook it, and he will succeed best as a practitioner who best appreciates the influence which cracked goblet, a chipped saucer, a soiled napkin, or, on the other hand, a hot plate or a touch of color in the shape of a leaf or flower, may have upon the capricious appetite of the sick. In ordering diet for convalescence it is not an uncommon error to select only those articles which are agreeable to the physician himself, forgetting the old proverb, that what is one man's meat may be another man's poison, and also that it is above all things desirable to avoid monotony. One doctor always orders chicken, another eggs, a third a mutton-chop, etc. The practice in this respect has probably been unduly influenced by the reports of Beaumont of the results of his observations on Alexis St. Martin, and we still find that the relative digestibility of various articles of food is estimated according to the scale laid down in these reports, with no allowance for individual peculiarities, previous habits, mode of cooking, etc. The secret of success in the diet of convalescence lies mainly in the simplicity of the individual dishes, in varying the different meals, in the manner of serving, and in carefully observing the effects on the sick person, and being guided by the results.

To promote appetite and digestion, and to secure refreshing sleep, one of the most important things is fresh air, but in many houses a sick person will obtain but a very limited allowance of this if the physician does not give special attention to the matter. Except in cases of contagious disease, the rules for managing which have been given in a previous section (p. 201), as soon as a patient is sufficiently recovered to be moved for a short time into another room his bedroom should be thoroughly aired and cleansed, and this should be done morning and evening thereafter.

In treating cases of contagious disease the question often arises as to means of individual prophylaxis to be used by those who must be exposed to the effects of the infected locality or of the presence of the sick. The attempts which have been made to secure this individual protection in the midst of an epidemic have been numerous and varied, ranging from the use of the "vinegar of the four thieves" of the Middle Ages to the employment of the sulphites and chlorates to make the blood unsuited to the growth and multiplication of the supposed germs, or of cotton-wool respirators to strain the infected air, or of supposed specifics for particular diseases, as belladonna for scarlet fever and vaccination against small-pox. As yet, there is little or no satisfactory evidence as to the value of individual precautions against those diseases whose contagion is conveyed through the air, small-pox alone excepted, but in case of diphtheria in one member of a family of children it might be well to try the use of chlorate of potash internally, combined with the local application of the tincture of the chloride of iron, as suggested by E. M. Hunt. The question is one to be investigated by careful observation and experiment; and, though it is improbable that any definite results will be obtained except in those diseases which are communicable to animals, and therefore {207} susceptible of direct experiment, still, it is possible that some advance may be made. In rare and exceptional cases--as, for instance, in exploring a crowded, filthy, and intensely infected typhus-fever nest, as a tenement-house, or an infected yellow-fever ship--it may be worth while for the physician or inspector who is unprotected by a previous attack of these diseases to make use of a cotton-wool respirator, which is readily extemporized, and belongs to that exceedingly valuable and popular class of remedies which, "if they do no good, can do no harm." In epidemics of typhus, cholera, or yellow fever one of the most valuable prophylactics is to have a mind so occupied with other matters that it pays little or no attention to the danger, while in case of small-pox fear of the disease is indirectly the best prophylactic, since it leads to careful vaccination.

This branch of the subject is closed with the remark that it would be well if physicians, and especially the younger ones, gave more attention to the preservation of their own health than many of them do. The possession of a medical diploma does not prevent the evil effects of irregular and hurried meals, insufficient sleep, exposure to inclement weather, and lack of systematic and sufficient exercise; and too much tobacco, sometimes too much alcohol, and in exceptional cases too much study and literary work, so often combine with anxiety about individual patients or with pecuniary worries to damage the digestion and nervous system of the young practitioner that the wonder is that so many survive the ordeal. And, in fact, the mortality among physicians under the age of thirty is higher than that of any other profession during the same period of life.

III. Public Hygiene in its Relations to Physicians.

An important difference between man and animals is found in the extent to which he will sacrifice a present pleasure or convenience to secure a future good or to avoid a future evil. The savage will do this to only a very limited extent--little more, in fact, than the beaver or the squirrel--and the lesson is learned but slowly and by sad experience. This is especially the case as regards matters affecting health. When a man begins to take special precautions as to his diet or exercise, having in view rather his future health than his present comfort and tastes, he has in most cases already begun to suffer from the effects of his imprudence, and does not commence a hygienic course of life as a perfectly sound and healthy person. The same is true for a community. It will not usually submit to the burden of taxation necessary to secure drains and sewers or a proper registration of vital statistics, nor to the cost and inconvenience of the machinery necessary to limit the spread of contagious diseases, until the neglect of these things has resulted in such an amount of disease and death as to forcibly call attention to the matter. The result is, that the burden is far heavier than it would have been had the work been undertaken in proper season, and individuals may find it to their interest to leave the place and settle elsewhere rather than remain and meet their proportion of the expense.

When a state or municipality has so far advanced in civilization as to consider it desirable to take measures to protect the public health by preventing individuals from polluting the air or water liable to be used by {208} their neighbors, etc., the services of the medical profession are always called upon. The foundation of public hygiene is information as to the occurrence of certain forms of disease, the cause of which can be referred with more or less precision to a certain limited locality. This information may be very imperfect, consisting of little more than rumor and opinions as to the existence of an undue amount of sickness or mortality in a certain place, or it may consist of precise reports setting forth the number of deaths from each cause, the proportion of each of these to the population by age, sex, occupation, etc., and of the whole to births--constituting what is commonly called the "vital statistics of a place"--and also of reports of the occurrence of certain preventable diseases; and between these two the information may be of various degrees of completeness, but, whatever there be, it is for the most part obtained either directly or indirectly from medical men. The reliability and completeness of the information thus obtained by the state determines to a great extent the direction and character of the work done in destroying or preventing the causes of disease, and it is also an important means of increasing our knowledge with regard to the nature of these causes.

The character of this information depends largely upon the character of the physicians who furnish it. In a large part of the country medicine is legally in the position of any common occupation; that is, the term "physician" is defined as applied to "any one who publicly announces himself to be a practitioner of this art, and undertakes to treat the sick either for or without reward." Under such circumstances there can be no guarantee that all who call themselves physicians are properly qualified or competent to furnish reliable information for registration purposes, and, as a matter of fact, a large number are not so qualified. It is for this reason that there is such a close connection between public health authorities, registration of vital statistics, and the registration of those physicians whose certificates as to causes of deaths, etc. will be accepted by the state; and hence the nature of the public health organization of a state and the personnel of its officials are matters of great importance to physicians. On the other hand, the efficiency of a public health service depends very largely upon the relations which it holds with, and the light in which it is regarded by, the medical profession. A health officer who is distrusted and disliked by the physicians of his district cannot effect much unless he can overcome this feeling, and his tenure of office must always be very insecure.

The official relations of the practitioner with the health authorities are usually confined to the subjects of registration of vital statistics and of checking the spread of contagious diseases. The most marked exception to this rule is furnished by the States of Alabama and North and South Carolina, in which the State Medical Society is the State Board of Health, having been given legislative powers and the right of selecting the health officers. The most complete organization of this kind is that of the State of Alabama, where by the act of 1875 the Medical Association of the State was constituted the State Board of Health, and the county medical societies in affiliation with the State Society were made county boards of health, to be under the general direction of the State Board. These county boards at first had advisory powers only, and were to be conducted without expense to the State or the county, except that the competent legal {209} authorities of any county might invest the county board with such powers and duties for the promotion of the public health as might be mutually agreed on; but in such case the right to elect or appoint those employed in sanitary administration is reserved to the board of health, while all questions relating to salaries, appropriations, and expenditures shall be reserved to the legal authorities. It was further provided "that no board of health, or advisory or executive medical body of any name or kind for the exercise of public health functions, shall be established by authority of law in any county-town or city of this State except such as are contemplated by the provisions of this act, the object of this prohibition being to secure a uniform system of sanitary supervision throughout the State." By an act of 1881 the county board is directed to elect a health officer, who is to keep a register of the births, deaths, and cases of pestilential or infectious diseases occurring in the county, and furnish to physicians, free of charge, reliable vaccine--to obtain information as to the sanitary condition of his county, etc. etc. It will be seen that this plan of organization is an attempt to overcome the practical difficulties in the way of obtaining from physicians the information necessary for the registration of vital statistics and the work of preventing the spread of infectious diseases.

While the great majority of physicians are willing to furnish the information as to the cause of death, etc. which is necessary for a useful registration, there are always some who either neglect or refuse to do so; and if the law be made compulsory, it provokes hostility unless compensation is furnished, while as regards the requiring physicians to furnish information as to the existence of contagious diseases, this always rouses opposition on the part of a certain number of medical men, even if payment for such notification is provided. And while this opposition is no doubt in many cases due to improper motives, such as personal hostility to the existing authorities, party politics, or a desire for notoriety, its strength nevertheless rests upon the fact that it is unjust for the state to compel the services of any man or class of men without furnishing compensation. The advocates of health and registration laws are thus placed between Scylla and Charybdis: if they propose compensation, which involves appropriations from the public treasury, the law cannot be passed; if there is no compensation allowed, complete results cannot be obtained.

The Alabama law makes compulsory the furnishing by physicians of information relating to births, deaths, and infectious diseases, and gives compensation--not in money, but by allowing the medical profession to have the sole management of the matter and to choose the health officers to whom they are to report; in other words, they are allowed to tax themselves. The result in Alabama is yet doubtful. If competent and faithful health officers and registrars can be obtained without paying them a fair compensation, it will be contrary to experience; and if these officers receive a salary, it will be strange if the positions do not become the reward of partisan political work.

It should be noted that the requiring a physician to report the births occurring in his practice stands on a very different basis from the requiring him to report the cause of death, since there is no special necessity for the former. It requires no expert knowledge to report a birth, and the duty should obviously devolve on the householder.

{210} In those States in which by law only properly qualified medical men, as determined by examination, have the right to practice, to hold medical office, or to furnish medical certificates, the State certainly is entitled to require of all physicians thus registered and authoritatively recommended to the people as competent, that they shall furnish, free of charge, certificates of the cause of death in those cases where they are cognizant of such cause.

States and municipalities often demand much more than this; as, for instance, that the medical man shall fill out the whole certificate, including age, nativity, nativity of parents, etc., and that he shall furnish the information to the registrar. In some cases it is provided that any physician having attended a person during his last illness shall furnish the certificate: this would apply to cases where the physician may not have seen the case for weeks before death.

While it is most convenient to have the certificate of cause of death upon the same form which contains the data necessary to identify the individual, the certificate should be distinct from the latter, and the duty of making the return to the registrar should devolve on the householder or undertaker, and not on the physician. On the other hand, it is easy for the physician to be hypercritical in these matters: his certificate is to be considered rather as a statement of opinion than as a statement of facts within his personal knowledge, precisely as he would certify as to his own age and birthplace.

The compulsory notification of infectious diseases to the health authorities is a matter presenting much greater difficulties than that of certificates as to causes of death. The state has no right to require such notification from the physician without giving some quid pro quo, and it is not expedient to make it compulsory, even with payment, except from physicians employed by the state or municipality, to furnish gratuitous medical attendance to the poor. The state has the right to require such information from the parent or householder, and it has also the right to require the physician to notify the parent or householder as soon as he recognizes the existence of such infectious disease. It is extremely desirable that the health authorities of a city should receive promptly, and direct from physicians, notification of the occurrence of such diseases, and there will usually be no difficulty in obtaining this if the health officer has tact and discretion and the city is prepared to do its duty. This duty is not confined to registering the information or placarding the house, nor will it be properly performed by merely removing the sick person to a hospital and disinfecting the premises. If the case occur in a family which can secure its proper isolation, and the attending physician certifies that it is so isolated and makes himself responsible for its management (for which responsibility he should be paid by the patient or his friends), the health officer should not interfere nor do more than furnish a competent person to secure disinfection if required. The employment of a trained nurse known by the health authorities to be competent and reliable would do away with most of the difficulties connected with such cases in the upper and middle classes of society; and such nurses should be registered just as physicians and midwives are.

Where the case cannot be thus isolated and properly cared for, it should be removed to a proper hospital. This presupposes that the city has such a hospital, and if it has not, and is not prepared for such cases, notification {211} is useless. When the city places a house in quarantine so as to interfere with business, it should be for the shortest possible time consistent with securing thorough disinfection of the premises, and the city should bear not only the cost of such disinfection, but the cost of caring for the persons in the house in an isolated place until no further danger is to be apprehended for them. When the city undertakes to pay all expenses for isolation and disinfection of such cases, it has the right to require that all such cases shall be so treated, leaving it to private parties to meet the cost in case they prefer not to use the buildings and apparatus provided by the city for that purpose. And when the city does its duty in this respect, it will be found that physicians and the people will do theirs, with rare exceptions.

When a city becomes very unhealthy the usual policy is to conceal the fact as much as possible, and to attribute the mortality to some other than the real cause. The influence of the mercantile part of the community is in such a case strongly exerted on the daily press and on the health authorities to produce such representations of the condition of things as will tend to allay apprehensions on the part of their customers. The healthfulness of a place is usually estimated from its mortality reports, but the reliability of these is by no means always what it should be. Yellow fever is called typho-malarial or pernicious fever, typhoid is reported as diarrhoea or malarial fever, etc. etc., and great stress is laid upon what is called the sanitary condition of the place, which is declared to be excellent.

Unfortunately, this phrase, "sanitary condition," means different things at different times. When the mortality is low, sanitary condition means the healthfulness of a place; when it is high, it means the cleanliness of a place. To a certain extent physicians are responsible for the truth of the statistical returns, not so much in relation to the number as to the causes of deaths; but none save those who have practised in a city liable to epidemics can realize the enormous pressure which is brought to bear on medical men to induce them to aid in or wink at concealing the true state of the case. Of course, this ostrich-like policy is in the long run an exceedingly unwise one, but neither the average householder nor community can be expected at present to pursue any other, except under pressure.

There are many questions as to the best form of public health organization, and the powers and duties which should be conferred upon it, which can only be properly answered by taking into consideration the circumstances in each case. In a large city the health officers must have great powers if they are to be really efficient. They have to contend with ignorance, custom, and self-interest, and their action must in many cases be prompt and unrestricted if it is to be efficacious. They must sometimes be in conflict with wealthy and powerful corporations, whose interests are opposed to the reforms which they urge, and although their business is to protect the most important interest of the community at large--_i.e._ its health--against the interests of individuals, yet these last are much more immediately concerned, and are, naturally, so active that they are often, although few in number, able to defeat any attempt to interfere with their occupations.

It not unfrequently happens that a health board may have all the power {212} necessary, so far as the laws are concerned, and yet may be able to accomplish little for want of funds to pay the inspectors and other officials whose services are necessary. For a city, a health officer usually does better work than a board of health: his responsibility is more direct, and he has stronger motives to do good work, than a board. Of course, a poor health officer is less efficient than a good board of health, but the general rule is as above stated. The problems of hygiene require special knowledge, and the man who is to deal with them requires special training. The folly of treating diseases by their names with popular or patent remedies is not greater than that of the attempt to make a healthy house or city by men who are not architects or engineers or physicians, or who have only the information possessed by the average architect or engineer or physician. And, of all professional or educated men, the physician especially should recognize his own ignorance. When he is asked what one should take for dyspepsia or pneumonia his answer is, "Take the advice of a physician;" and so when he is asked how the plumbing of a house should be arranged, how a hospital should be ventilated, how a city should be sewered, how a marsh should be dealt with or a water-supply provided, he should reply, "Get expert advice and supervision, and be prepared to pay the amount necessary to secure it." It is the special duty of the physician to exert his influence to secure properly constituted sanitary authorities for his own locality, his State, and for the nation, and to support these against the hostility which they must inevitably arouse if they are efficient. And he should do this, not blindly and as a partisan, but intelligently and with due consideration of all the important interests involved.

The body of educated physicians in a community forms the tribunal by which the work of sanitary officials is to be judged, and they cannot judge wisely unless they appreciate the difficulties with which health officials have to contend. If a city has an incompetent or dishonest board of health, the medical profession of that city are to a certain extent responsible for it; if a competent, energetic, and faithful sanitary officer is crippled and harassed or forced out of office because he is on the wrong side of politics, or because in the legitimate and proper exercise of his functions he has come in conflict with the interests of powerful and wealthy individuals or corporations, it is the duty of medical men to support him, and to do this actively and promptly. And I take great pleasure in being able to say, as the result of somewhat extended observation, that, as a rule, the physicians of this country do cheerfully and promptly co-operate with the sanitary authorities where such exist, and are the first to try to have them properly organized and given the necessary means and powers to do effective work.

DRAINAGE AND SEWERAGE IN THEIR HYGIENIC RELATIONS.

BY GEO. E. WARING, JR.

For reasons, sometimes sound and sometimes fanciful, the drainage question often presents itself to the medical practitioner as an annoying if not as a serious one. It is not necessary for the physician to make himself an adept in the art of sanitary drainage, but he can properly meet neither the demands of nervous patients nor the exigencies of sometimes serious situations without having an intelligent general idea concerning it. Not only to prescribe improvement, but frequently to allay ill-grounded apprehension, he should be able to address himself, intelligently and promptly, at least to the few simple problems presented in connection with ordinary houses. I use the expression "ill-grounded apprehension," not because the drainage in and about houses is generally tolerably good, for it is not, but because the race seems to have so inured itself to certain grave defects in plumbing-work that one may reasonably hesitate, and look elsewhere for the occasion of diseases before accusing the imperfect sanitary appliances of an average house.

Anything like a treatise on the technical details of house-drainage would be quite out of place here. There are note-books easily accessible to such physicians as care to make a thorough study of the subject. It does seem worth while, however, to pass in careful review, in a work of this character, the various conditions of interior and exterior drainage upon which a physician is frequently called to pass judgment.

The perfect drainage of a house, like the perfect drainage of a town, implies the immediate and complete removal, to a point well beyond its limits, of all waste matters which are a proper subject of water-carriage; such a thorough ventilation of the channel which these matters have traversed as to reduce to a minimum the production of deleterious gases arising from the decomposition of the film with which they may have soiled the walls of their conduit; and adequate provision for the absolute and permanent exclusion from the atmosphere within the house of the air of the pipe or sewer. This is a brief and simple statement of the fundamental and absolute requirements of all good drainage. It is founded on the one grand object which governs all improvement of this character: the prevention of decomposition of refuse matters anywhere in house or town.

Practically, it is safe to say that these conditions are never complete, and that instances of perfect work are so exceptional as to need no {214} consideration here. We have to assume, substantially in every case that is presented, that we are dealing with defective work, ordinarily with work that is very seriously defective. Most houses have been built by contractors, and the plumbing is perhaps the item of the whole structure that it is considered easiest and safest to scamp or to neglect. Even where the motive of economy has had no controlling influence, the drainage has almost invariably been planned by a plumber who has learned his trade and conceived his ideas in the performance of work which was done at a time when no one realized the serious consequences of its being improperly done. The absence of interior ventilation, leaky joints, ill-arranged connections between the various plumbing appliances and the main outlet from the house, pipes and traps so large that an ordinary current is powerless to keep them clean, defects of form, defects of material, and defects of construction, are met with on every hand. This general statement is of itself sufficient to show how hopeless it is for the average physician to prescribe the manner in which the drainage of a house should be constructed or remodelled.

If we view the question solely with reference to its bearing on the causation of disease, we enter a field where neither the sanitarian nor the physician is ever sure of his footing. The precise relation between bad drainage and ill-health no man knows. Certain diseases are undoubtedly traceable to conditions of air or of drinking-water due to the improper disposal of organic wastes, but the extent and exact bearing of these influences are still greatly a matter of conjecture. It is, however, undoubtedly safe to assume--and the assumption is supported by ample general observation, if not by precisely ascertained facts--that whether we are considering serious diseases or the slighter ailments, every argument leads to the enforcement of the most strenuous requirements of cleanliness. Through all the ages no one has disputed, and no one has improved upon, the simple sanitary formula, "Pure air, pure water, and a pure soil." We may safely wait until the enthusiastic investigators now engaged with the subject shall have adduced the testimony of positive facts, if we will in the mean time adhere strictly to the requirements of Hippocrates' prescription. The physician will surely not go wrong if he treats all obvious defects of drainage as positive evils, and insists upon their complete reformation.

Not to confine ourselves to houses which are provided with the ordinary modern plumbing-works, but to include all collateral branches of the subject, we have to consider the following conditions:

I. THE REMOVAL OF HUMAN EXCREMENT:
(_a_) By water-carriage in houses provided with modern plumbing;
(_b_) By some form of dry conservancy;
(_c_) By the fiendish privy-vault which prevails so generally,
save in the larger cities.
II. THE REMOVAL OF LIQUID HOUSEHOLD WASTES:
(_a_) By delivery to public sewers;
(_b_) By irrigation disposal;
(_c_) By delivery into cesspools.

Incidentally to the above there must be considered the influences of the ultimate disposal of all household waste, whether by the public sewer or the private house-drain.
