The fact that, by request of a committee, this paper has been prepared to “open a discussion” on the etiology and pathology of typhoid fever, implies that neither of these two branches of the subject is settled. In connection with both branches, there are, however, very many facts which are more or less well established; so it must be one function of this paper to recall to our minds some of these facts, and, if possible, to do this in such order as shall suggest harmonious interpretations of the facts, to aid us in arriving at conclusions concerning the etiology and pathology of this important disease. 1. Filth as a Factor in the Causation of Typhoid Fever. It seems to me that it is established that typhoid fever is a “filth disease,” that is, that what we know as “filth” has had much to do in the causation of typhoid fever. ♦ A paper read at the meeting of the Michigan State Medical Society, June 4,1896. THE ETIOLOGY AND PATHOLOGY OF TYPHOID FEVER. The eminent Sanitarian, Dr. Joseph von Foder, compiled the facts rela- tive to the surroundings of fatal cases of typhoid fever in Buda Pesth, Hungary, during fifteen years—lB6B-77, with results as follows;—* Deaths from typhoid fever per hundred houses when the interior of the dwelling was:— 1. Yery clean 165 2. Clean 177 3. Dirty 182 4. Yery dirty 356 There was gradual increase from “very clean” to “dirty,” and a very great increase from “dirty” to “very dirty.” Compared with the “very ©lean,” there were more than twice the proportion of deaths in the “very dirty” dwellings. With the yards surrounding the houses, the result was as follows:— Typhoid fever deaths per one hundred houses when the yard was:— 1. Very clean 159 2. Clean 186 3. Dirty 208 4. Yery dirty 282 The evidence was conclusive that want of cleanliness outside the dwell- ing had great influence in the causation of typhoid fever, but not nearly as great as had want of cleanliness inside the dwelling. Other evidence that filth is a factor in the causation of typhoid fever, is the experience in Munich before and since the filth of the city has been promptly carried out of the city by means of sewerage: Thus, in 1852-9 when the drinking water was from wells, and the human excreta was stored in overlying vaults, the mortality from typhoid fever was 24.2 per 10,000 inhabitants. In 1860 the vaults were required to be cemented; in 1860-7 the typhoid mortality was reduced to 16.6 per 10,000. In 1866-78 a system of sewers was commenced, involving the commencement of the use of a general water-supply; in 1868-75 the typhoid mortality fell to 12.7. The sewers were continued in 1874-80, in 1877-79 the typhoid mortality was reduced to 7.8. In 1881-4 the sewers were further continued, and a good spring water was added to the general water-supply; the typhoid mortality decreased, until in 1884 it was only 1.4 per 10,000 inhabitants.! The death rate from typhoid was then only about one-seventeenth what it had been when Munich drank water into which human filth percolated. This indicates the nature of the filth which seems to have causal rela- tion to typhoid fever,—the excretions of human bodies. This evidence of the etiology is in harmony with some of the evidence of the pathology of the disease,—one approved name of the disease is “enteric fever”; an important effect of the disease is in the intestine; it is reasonable to sup- pose that the cause of the disease may be given off from that part of the body in which the pathological change occurs. Apparently this is true; the disease appears to be spread by a cause which goes from the intestine,| and is capable of producing the disease when it reaches the intestine of another person. * Archiv fur Hygiene Zweiter Band, 18s4.

[PLATE NO. 651.] THE ETIOLOGY AND PATHOLOGY OF TYPHOID FEYER, Typhoid Fever Among Plumbers. In a report of the Board of Health of Montclair, New Jersey, mention was made of a plumber being attacked by typhoid fever in consequence of having made repairs in one or more of the houses in which the fever had occurred.* A similar case occurred under my observation Michigan, a few years ago. Is the Cause a Chemical Poison, or is it Specific. Many classes of facts seem to demonstrate that the cause1 of typhoid fever cannot be simply a non-living chemical poison not capable of repro- duction, and that it must be an organized body capable of reproduction and continuous multiplication./ For instance, as an illustration, from a house in Philadelphia in which there was typhoid fever, a man went to Plymouth, Pa., was taken sick with typhoid fever, his discharges were thrown out on the snow which melted and was washed into a small mountain stream which served as the source of a public water-supply. In a short time about a thousand persons who drank that water contracted typhoid fever, while many other persons in the same village who drank water from wells, the water from which when analyzed at the laboratory of the Michigan State Agricultural College was found to be very much more badly contaminated with leachings from human excreta, did not then contract typhoid fever; although, afterwards, when there had been opportunity for the privies to have been “infected” with typhoid discharges, the disease appeared, in some instances, to have been contracted from water in the underlying wells. In the mountain stream the dilution was such as to make it impossible that so many cases of fever could have been caused by any chemical poison; there must have been reproduction of the “infection” in the intestines of the patients. And the contaminated well water did not cause typhoid fever until after it became infected. At Cumberland, Md., in 1889-90, the evidence is that typhoid fever was not present until the discharges from a typhoid patient living on one of the little streams which empties into the Potomac about 200 feet above the pumping station, found their way into the city water supply, f Dr. Kober, who has made a special study of the subject, says: “Such instances can be recited by the hundreds.”! lam myself familiar with many such instances. In a great many instances, notably the outbreak at Plymouth, Pa., the tendency of such evidence is to prove that typhoid fever is not caused by non-infected human excreta; but by excreta of typhoid fever patients. This is equivalent to saying that typhoid fever is caused by a specific organism, or organisms. The Practical Restriction of Typhoid Fever Proves its Communicability. The lessening of typhoid fever by sewerage and improved water-supplies, shown in diagrams and charts I and 11, submitted herewith, J is evidence that typhoid fever is communicable, and that it may be restricted by the measures mentioned. ♦Jour.

A similar line of evidence is that in the diagram, entitled “Lives Saved by Public-Health Work,”* wherein it is shown that during those years in which the State Board of Health has been laboring for the restriction of typhoid fever the mortality has been less than it was before. That diagram relates to the entire State; if we confine the inquiry to local outbreaks, and separate them into two classes, as is done in the construction of the diagrams “Isolation and Disinfection Restrict Typhoid Fever,”f it is plain that isolation and disinfection restrict typhoid fever, which implies that it is a communicable disease. The disinfection includes that of the bowel dis- charges from the patient; and it should, by all means, have included that of everything in any way soiled by their urine which, in some instances, has been found to be almost a pure culture of the typhoid bacillus.J In the outbreaks studied, probably the urine, dried on linen, has been entirely overlooked as a cause of typhoid fever. But the evidence seems to be conclusive that in townships, villages, and small cities typhoid fever may be restricted so that only about two cases, and an average of one-fourth of one death shall occur to each outbreak. In the year 1891 a few epidemics greatly increased the average in localities where isolation and disinfection were neglected, but the results of isolation and disinfection were about the same as in the other years. It seems to me to be established that typhoid fever is a specific communi- cable disease. How is it communicated? The facts relative to the lessening of typhoid fever in Munich, and facts of similar import in cities throughout the world, seem to demonstrate that the prompt removal of excreta by sewers, associated as that usually is with an uncontaminated water supply, decreases the spread of typhoid fever. “The example of Dantzig, however, shows that an abundant water-supply alone does not diminish the death-rate. This city was supplied with water in 1869, and sewered in 1872. No marked diminution in the death-rate of typhoid fever occurred until after the introduction of the sewers. Wash- ington, with a daily individual supply of 177 gallons, has an average annual mortality of 6.2, while New York, with 74 gallons per capita, has 8.1 deaths yearly to 10,000 population. Abundance of water alone, as might well be supposed, does not limit the spread of typhoid fever.”§ In such cities as have sewerage but still have a contaminated water supply, typhoid fever still remains. Philadelphia is an example. Chicago has been a noted example. Cities like New Orleans where there have been imperfect sewerage, but a water supply from rain-water cisterns not much contaminated by human excreta, do not suffer much from typhoid fever. Logically it seems to follow that the large part of the typhoid fever must be caused by the typhoid excreta in the drinking water. . / There are on record specific instances too numerous to mention where typhoid fever epidemics and local outbreaks have been traced to the use of water infected with excreta of a typhoid fever patient. Typhoid Fever is a Communicable Disease Sometimes Waterborne. * Page cxlviii, [ f Pages cxlix, cli and clii. ± Experiments made by Wright and Semple, London Lancet July 27,1895, Vol. 11, No. 4, page 196. § Report of Medical Society Dist. of Columbia, in Journal Am.

[PLATE NO, 1681.] STATE BOARD OF HEALTH-REPORT OF SECRETARY, 1896. Low Water in Wells and Typhoid Fever. The foregoing leads naturally to an interpretation of the facts concerning the very close relation of low water in wells to typhoid fever in localities dependent upon wells for the water-supply. Many years ago Dr. George E. Ranney, then Secretary, and later President of this Society, called attention to an increase in typhoid fever at a time of low water in wells. Dr. Poster Pratt, also an Ex-President of this Society, spoke, in June, 1874, of a similar circumstance under his observation. With a view of studying the subject systematically, about 20 years ago, I induced regular observations and records of the depth of water in wells in Michigan; five or six years later I tabulated the results, and found a very striking relation. Herewith is a diagram (Plate No. 681)* exhibiting the facts for 14 years, 1878 and 1880-92. It is plain that the relation is very nearly quantitative. The lower the water the more typhoid fever. Prof. Max von Pettenkofer was the first to make a systematic study of this subject, and he established the fact of a very close relation of typhoid fever and ground water in Munich.f His interpretation of the fact, how- ever, was not that the disease was caused by drinking in the germs with the infected water, as was my belief; but that it was caused by breathing typhoid germ-laden air forced out of the ground by fluctuations of atmos- pheric pressure. This cannot be the true explanation of the facts in Michigan, because my tables and diagrams show that the average daily range of atmospheric pressure does not sustain such relations to typhoid fever as to make this possible; the range of pressure is at its minimum in July and its maximum in January, while typhoid fever has its minimum in April and May, and its maximum in October; and a curve representing its increase and decrease shows no influence of the atmospheric pressure. On the other hand, the drinking-water interpretation takes account of the fact that in times of low ground water a well in use drains a wider area,, and is therefore more liable than in times of high ground water to be infected by leachings from more privies at a distance. Again, it takes account of the fact that any infection which may reach the well will be much more diluted when the groundwater is high than when it is low; the chances of contracting typhoid fever are, therefore, greater when the water is low. There is another interpretation which may be true under some circum- stances, not, however, so universal as the drinking-water explanation, but which may contribute toward the same result. When the ground water is low the surface of the earth will generally be dry. Human excreta on the surface of the earth or in shallow receptacles will, more generally than when the ground water is high, be in a condition to permit the wind to detach any typhoid germs which may be on its surface or which may be trampled into dust, and to float them off, to infect air, food or drink, or to be washed from roofs of buildings into the rain-water cistern. Typhoid Fever Spread hy Milk. Mr. Ernest Hart has collected and tabulated facts relative to 50 outbreaks of typhoid fever spread by milk. * Page cliii. f “ Boden and Grundwasser,” etc., by Pettenkofer, Munich, 1869 THE ETIOLOGY AND PATHOLOGY OF TYPHOID FEVER. In the report of the health officer of the District of Columbia for 1895.* Mr. Hart’s tabulation is included with 88 other outbreaks collected by Drs. Busey and Kober; altogether there are tabulated the details of date, place, number of cases, deaths, circumstances of outbreak, reporter, and reference to publication, relative to one hundred and thirty-eight outbreaks of typhoid fever in different patts of the world, believed to have been caused by infected milk. (The table, with additions collected by myself, is sub- mitted as an appendix to this paper.) Many of the outbreaks caused by infected milk were traced further back to infected water, used, in 51 instances for washing the cans and utensils. In 14 instances the intentional dilution of the milk with polluted water is admitted. In six instances the infection is attributed to the cows drinking or wading in sewage-polluted water thus infecting the udder, and finally the milk. In three instances the infection was spread in ice cream prepared in infected premises. In 21 instances the dairy employees also acted as nurses.f In outbreak No. 1 reported by Dr. Taylor, in Edinburg Med. Jour., May, 1858, “the outbreak, which affected 7 families, was traced to a supply derived from a milk-man in whose cottage were cases of typhoid fever. The milk was kept in the kitchen, where the children lay, and the mother, who was the nurse, also milked the cows.”* In a few instances water seemed to have no part in the spread of the disease. Typhoid Fever Spread by Oysters. Uncooked oysters “fattened” in typhoid-infected waters are now known to be a means of spreading typhoid fever. An outbreak due to this cause, at Wesleyan University, Middletown, Conn., in October, 1894, was thoroughly investigated, and the results published in the report of the Connecticut State Board of Health for 1894. J Two cases of typhoid fever, the discharges from which went through a private sewer into the Quinnipiac River near where the oysters were placed in fresh water to “fatten,”—absorb fresh water—just before they were to be used, were the source and cause of the outbreak. Twenty-three students and six other persons who attended the banquet, contracted the disease. The general subject of typhoid bacteriology and oysters in salt and fresh waters, at ordinary temperatures, was afterwards investigated by Charles J. Foote, Demonstrator of Bacteriology in Yale University.§ “Many bacilli were found in the oyster juice and in the stomach of the oyster a month after infection, from which it appears that typhoid bacilli may live even longer in the oyster than in the water which surrounds it, from which they usually disappear within three weeks when new infection does not occur.”^[ Typhoid Fever Spread by Infected Clothing. Dr. Kober in the report of the health officer of the District of Colum- bia, for 1895, page 259, summarizes a report by Gelau as follows: “A Ger- man artillery regiment, with an average mean strength of 358 men, between the years 1873 and 1884 furnished not less than 146 cases of typhoid fever. * Pages 346-364. t Page 330. + Report by H. W. Conn. Professor of Biology, Wesleyan University, pp. 243-264. § Med. News, Mar. 23,1895. T Modern Medicine, Feb., 18P6, p. 40. STATE BOARD OF HEALTH—REPORT OF SECRETARY, 1896. The water-supply was above suspicion, disinfection of the quarters and even abandonment of the barracks failed to check the disease. This fin- ally led to the suspicion that the clothing might be the source of infection, especially as the garments were promiscuously worn. Examination revealed the presence of fecal spots in a number of pantaloons. The clothing was now disinfected, after which only three mild cases appeared, and these were confined to the men engaged in disinfection.” In several instances brought to my notice but not published, typhoid fever has, apparently, been contracted by taking the specific cause into the mouth with the air inhaled. In two such instances the nurses who con- tracted the disease slept in the same room with their patients. Bearing in mind the frequency with which a sleeping person breathes through the mouth, and the fact that then the normal protection of the nose with its moist hairs, disinfecting saline mucus, constantly flowing downward to be evaporated and imprison incoming dust and germs, one may realize the greater liability of a sleeping person to contract typhoid fever. In the Southern States it has many times been observed that yellow fever is much more often contracted by sleeping in an infected locality than by visiting it in the daytime. While investigating an outbreak of typhoid fever in the State Prison at Jackson, I contracted typhoid fever notwithstanding I took no food or water while there. The outbreak occurred soon after a new prisoner had come into the prison, and the disease was apparently spread in more ways than one, but not through the drinking water. A wooden bucket in each cell every night was emptied every morning, and an attempt made to dis- infect it by rinsing it with a disinfecting solution; but inspection led me to think that the disinfection was not complete, so it is possible that some of the cases were caused by emanations from an infected bucket, because no effort was made to have the same bucket go to the same cell every night. Among the first persons about the prison to contract typhoid fever, was the guard who was stationed on top of the wall immediately over the place where the buckets were each morning emptied into the sewer, then rinsed and placed in rows to be dried and aired during the day. The typhoid patients were put in the hospital on the fourth floor of the central build- ing, and their dejecta went into a Soil-pipe in which there Was a break, or from which air could pass through a “dead-end” to a sewer under the lowest floor. In cells along a line between this source of sewer air and a very large ventilator at the other end of the room, prisoners contracted typhoid fever, so there was reason to believe that the disease was spread through the air from the soil-pipe, on its way to the ventilator. To answer the question whether this was possible, because it was known that micro-organisms are not given off to the air from moist surfaces, a bottle was sterilized, filled with sterilized water, the bottle held in the “dead-end” to the sewer, the water allowed to run out, and the bottle to fill with air from the sewer. While this was being done, the soil-pipe from the hospital on the fourth floor was flushed, foul air rushed out but no .fluid or solid came near the bottle. Meantime, with other members of the State Board of Health, I was standing near in conversation with the Warden of the Prison, The bottle was taken by Prof. Vaughan to the laboratory at the University, and I Typhoid Fever Spread Through the Air. THE ETIOLOGY AND PATHOLOGY OF TYPHOID FEYER. understand that Prof. Yaughan found the bacillus of Eberth or at least a pathogenic bacillus in its interior. Soon after my return home, I was mildly sick for nearly three weeks, with unmistakable typhoid fever, contracted apparently through the atmosphere. A few years ago, there was typhoid fever in Iron Mountain, Michigan, and it was especially noticeable to Dr. Anderson, then in that city, that there were most fever cases in houses the rear ends of which were on the three sides of a sort of court in which were numerous foul privies which in wet times drained into a foul pond near the center of the court, but which in a dry time permitted their overflowed contents to be trampled by those who passed through into dust to be blown about by the winds. One windy day, I inspected the locality, and it was easy to understand that if the specific cause of typhoid fever had been deposited in any one of the privies, its dissemination by the wind would be almost certain, because the germ is not rapidly destroyed by drying. What is the Specific Cause of Typhoid Fever? Dr. George M, Kober, of Washington, D. C., in a recent report on the subject, after giving different views of the specific cause, has said; “All scientific physicians agree, however, upon one point, viz., that typhoid fever is caused by an organized germ capable of reproducing itself within and without the body.”* Just here, however, is where we arrive at a point in the etiology where differences of opinion exist; for, while a majority of the prominent bac- teriologists conclude that the Bacillus typhosus demonstrated in typhoid cadavers by Eberth in 1880, and obtained in pure cultures by Gaffky in 1884, is the sole and only cause of typhoid fever, there are those who regard this as, to say the least, “not proven.” Thus, the last edition of “Ptomains and Leucomains” by Vaughan and Novy, says: “In this belief Yaughan refuses to concur, and claims that the Eberth bacillus as found in the spleen after death is an involution-form of any one of a number of germs which are found in certain waters. Yaughan claims that the typhoid bacilli can be detected in drinking-water by the following characteristics: (1) They grow at 37°, while many of the non-pathogenic germs of water grow only at lower temperatures. (2) They are pathogenic to rats, guinea- pigs, mice, and rabbits. (3) They do not coagulate milk. (4) When grown in milk or gelatin colored blue with litmus, the color is not altered.”! A recent writer has stated that the pathology of typhoid fever has long been known, but the etiology has only recently been discovered. In this paper I shall endeavor to omit so much of the pathology as has very long been known, and devote all the time I am permitted to use to the considera- tion of a few points in pathology which are comparatively new. And, to my mind, there are a number of important facts in pathology which have not very long been known; facts which could not be fully appreciated until considerable progress had been made in the etiology of the disease, Eor instance, the significance of abscesses, in various parts of the body, could not be appreciated until the bacteriologists had investigated the pus in THE PATHOLOGY OF TYPHOID FEVER. * Report of Health Officer of the District of Columbia, 1893, p. 257. + Edition 1896, page 208. STATE BOARD OF HEALTH—REPORT OF SECRETARY, 1896. those abscesses, and found there the apparent specific cause of typhoid fever. A new light is thrown on the pathology of typhoid fever by the knowledge that the specific germ has been found in the blood, and in nearly every organ and tissue of the body. This supports the view that typhoid fever is a disease of general blood infection. New light is supplied by the knowledge that the life-processes of the germs produce a poison, the effects of which, in various parts of the body, are important. Thus “Sanarelli’s prolonged studies upon experimental typhoid fever lead him to maintain that the intestinal disturbances in this disease are due to the toxin, and not to the local action of the typhoid bacteria.”* “Agro (Annales de Micrographie, vi., 1894) has discovered the very interesting fact that the mixture of the cultures of bacilli coli and bacillus typhi abdominalis has greater toxic power than a similar quantity of either in pure culture/’f “In 1889 Vaughan isolated from mixed cultures from typhoid stools a base, forming crystalline salts and capable of inducing in cats and dogs a marked elevation of temperature accompanied by severe purging.”* “In 1890 Vaughan reported the isolation, from water supposed to cause typhoid fever, of a number of toxicogenic germs. The chemic products of two of these have been studied. They belong to the proteids, and an analysis of one of them by Freer shows it to belong to the nucleins In a paper read at the meeting of the American Medical Association at Baltimore, in 1895, William B. Noyes, M. D., of New York, after stating the proportions of children in each of numerous epidemics in Europe and in this country, says: “In conclusion, we would once more emphasize that typhoid in early infancy in a typical form is rare in this country, though not uncommon abroad. It is in a mild or abortive form that we much look for it here, if we wish to separate it from other intestinal or meningeal diseases that may appear.” Dr. Noyes says;— “ The pathologic changes in the infantile cases, while distinct, are much less severe than in adults. It is a very interesting fact that in a series of animal inoculations with typhoid bacilli by Santerelli (Annals de L'lnstitute Pasteur, 1892-1594) the changes in the intestine and other viscera were almost identical with those we have just described in children. These experiments consisted of a series of inoculations of rabbits, guinea pigs, white mice and monkeys with pure cultures of the Eberth bacil- lus, and were followed by a second series of experiments of inoculations with sterilized filtered pro- ducts of the Eberth bacillus. The results were similar in the two cases. Swollen hyperemic spleen, congested intestine, diarrheal intestinal contents, infiltrated and congested Peyer’s patches, red and hypertrophied solitary follicles. Hardened microscopic sections of the intestine showed a change in the epithelial lining, especially, and detachment of masses of epithelial cells together, such as occurs in a poisoning by arsenic or other corrosive drugs. Enormous infiltration of Peyer's patches occurred, abundant accumulation of lymphoid cells in and around the follicles and invading the sub- mucous spaces. This change was not a simple hypertrophy of lymphatic plaques, but a condition just short of a beginning purulent infiltration. No typhoid bacilli could be found in these Peyer’s patches in the animal, but enormous numbers were seen in the adjacent lymphatic glands and in the connective tissue of the mesentery. From these experiments, Santerelli comes to the conclusion that typhoid fever produced in animals is by preference an infection of the lymphatic system, and the toxin pro- duced by the Eberth bacillus causes the anatomic lesions. These changes occur in all mucous surfaces and we should expect to find in both animals and in man, lesions in the mucous membrane of the mouth, larynx, bronchi and stomach with resulting symptoms which occur very frequently. Typhoid fever can no more truly be called a disease of the intestine than small-pox of the skin, though both have their characteristic lesions in those places.”-—Jour. Amer. Med. Assoc.

THE ETIOLOGY AND PATHOLOGY OF TYPHOID FEVER. “Stern {Volkmann's Sammlung klinischer Vortrage, No. 138) has published another suggestive paper on typhoid.” * * * “ The question as to the presence of typhoid bacilli in the blood was tested in six cases, with positive results in three ; twice in blood from roseohe and once in blood from a vein. In the negative cases the blood was examined only once in two of the three cases. In the third case, confirmed by autopsy, three examinations were negative. In the cases with positive results the number of colonies was always small, as has been found by other investigators. The bacilli were found between the ninth and twenty-fifth days of the disease.

In the course of a little while an abscess formed beneath the right deltoid, and an incision evacuated a quantity of pus mixed with blood.” * * * “Bacteriologic investigation of the pus evacuated from the abscess about the joint disclosed the presence of typhoid bacilli exclusively.’’J Pylephlebitis and Abscess of the Liver Following Typhoid Fever. “Lannois has recently described pylephlebitis and abscess of the liver following typhoid, in which the bacillus of was present in the pus from the abscess, though not in pure culture.”§ Intrauterine Infection with Typhoid. “Freund and Levy (Berliner klinische Wochenschrift, 1895, No. 25) report the case of a multigravida who was admitted to the hospital in the eighth day of typhoid, being five months pregnant. She progressed fav- orably until the fourth week, the temperature being but slightly elevated. Without apparent cause she expelled a living foetus, which soon perished. Her temperature rose during labor, but fell immediately afterwards. The foetus and placenta were received in sterile glass vessels, and an examina- tion made of the spleen, blood of the heart, and placenta twenty minutes after birth. No gross lesions were found. Typhoid bacilli developed, however, after incubation.” * * * “The case is a remarkable demonstration of the direct passage of infec- tion from mother to child, without anatomical lesions.”)] Suppurative Parotitis Caused by the Typhoid Bacillus. “To the list of suppurative processes complicating typhoid fever, in which the typhoid bacillus alone has been found as the cause of the abscess * Amer.

The diagnosis of typhoid fever was first made on the autopsy-table, Beyer’s patches showing distinct appear- ances of recently-healed ulceration. The right parotid gland was found to be infiltrated with pus, which was in places collected in small abscesses. Cultures from this pus developed only the typhoid bacillus, whose idenity was carefully proved with comparison of known cultures of the typhoid bacillus and of the bacillus coli communisJ In a paper read at the meeting of the American Medical Association in 1889, Professor Yaughan, in speaking of the Eberth bacillus, said:—“Gaffky and others found it always present in the mesenteric glands and spleen, often in the liver, and not so frequently in the kidney. In the intestine it has been found in the early stages in the swollen follicles and plaques and in the deeper layers, before there is any necrosis; but with the advent of ulcera- tion there is found secondary invasion. But in addition to these organs, the Eberth germ has been reported by Chantemesse and Yidal in the lungs of typhoid patients with bronchitis, broncho-pneumonia, and pneumonia. The same observers report the germ in the brain, Curschmann in the spinal cord, Zenker and Hoffmann in the voluntary muscles and in the marrow of the bones, and Rehtr, Neuhauss and Chantemesse and Yidal in the placenta of typhoid patients. In twenty samples of blood taken from the finger, during life, of typhoid patients, Meisels reports the finding of this germ in nineteen. Neuhauss examined the blood taken from the eruptive spots in typhoid fever with success. Maraglinao and others examine the blood taken from the spleen during life as a means of diagnosis.” * * * “Granting that these observers have not been mistaken in the nature of the germ which they have found, we must admit that the Eberth germ is widely distributed.”§ In the same paper Dr. Yaughan says; “To sum up the evidence which we have found on this point we may say: (1) The Eberth germ is found invariably in the bodies of those dead from typhoid fever. (2) It has been isolated and grown in pure cultures. (8) All attempts to induce typhoid fever in the lower animals by inoculation with this germ have so far been without success. (4) Experiments show not only that the germs fail to multiply in the lower animals, but that when introduced by inoculation it soon died. * * * But the bacteriologist stops here and says; ‘The lower animals do not have typhoid fever, and we must not conclude from the failure to induce this disease in them with Eberth’s germ that this bacillus is not the true cause of typhoid fever.’ ‘lf we could experiment upon man,’ says he, T have no doubt that we could be successful.’ Because the chemical products of the Eberth bacillus had not been demonstrated to be capable of producing the characteristic symptoms and lesions of typhoid fever, Dr. Vaughan then said; “We certainly cannot say that the Eberth germ has been demonstrated to be the true and sufficient cause of typhoid fever.” j) ♦ Cenralblatt f.

But in that same address Dr. Vaughan gave details of the inoculation of several dogs with a pure culture of germs resembling the Eberth bacillus, and in several instances the pathological results resembled those of typhoid fever in man. Dr. Vaughan said: “Notwithstanding the marked resemblance of our cultures to those of the Eberth germ, I must conclude from the effects obtained that we either had a wholly different organism or an impure culture.”* Other investigators believe that typhoid fever is due to a mixed infection. Typhoid Bacilli in the Urine; Typhoid Fever a General Blood Infection, One of the most important ideas, however, is the view set forth by Drs. Wright and Semple, professor and assistant professor of pathology in the British Army Medical School at Netley, based partly upon their experi- ments on the infectivity of the urine in typhoid fever, which had been previously pointed out by Sanarelli working under the auspices of Metsch- nikoff, but on which fact Drs. Wright and Semple build up still further Sanarelli’s new theory on the pathology of typhoid fever. Drs. Wright and Semple found the typhoid bacillus in the urine of six out of seven cases of typhoid fever. “In some cases the urine, even before incubation, is absolutely turbid with typhoid bacilli.”f They say:J “ The theory of typhoid fever, which is currently held and currently acted upon, is the theory that typhoid fever is an ' intoxication process’ much in the same way as cholera is an ‘ intoxication process. In other words it is assumed that the typhoid bacillus vegetates in the intestine, that it effects a lodg-. ment in the intestinal walls and that the poisons which are elaborated by the bacelli are absorbed into the system from the intestine. The systemic disturbance which characterizes typhoid fever is attributed to this absorption. This theory of typhoid fever is brought into harmony with notorious bacteriological facts by the assumption that there is a certain leakage of typhoid bacilli from the intestine into the system. This leakage theory is supposed to dispose of the fact that typhoid bacilli are invariably found in the spleen and mesenteric glands of patients suffering with typhoid fever. Now, this ‘intoxication’ theory of typhoid fever was originally based upon the fact that a bacillus which is morphologically indistinguishable from the typhoid bacillus is found in large quantities in the stools in every case of typhoid fever. Subsequent investigation, however, showed that this bacillus which predominates in the intestinal floor in cases of typhoid fever can be distinguished from the true typhoid fever bacillus by a series of chemical differences. The bacillus which is found in large quantities in the stools of patients suffering from typhoid fever is therefore not the true typhoid bacillus. It is the bacillus which is known by the name of ‘ Bacillus coli communis.’ Recent research has therefore been directed to the question as to whether, in addition to the bacillus coli communis, the true typhoid bacillus is not also to be found in the stools of patients suffering from typhoid fever. The following are the results of careful examination of this question: The true type of typhoid bacillus was detected in the stools of only four of the twelve cases of typhoid fever which were studied by Wathelet. In the case of these four patients the typhoid bacillus was detected only four times in a total of twenty- four examinations and even on these four occasions the true typhoid bacillus was outnumbered by the bacillus coli communis in the proportion of about three to one. In the case of the other eight cases of typhoid fever the bacillus appeared to be absent from the stools throughout the whole course of the disease. Wathelet has further shown that if the bacillus typhosus and the bacillus coli communis are implanted into one and the same tube of nutrient broth the bacillus coli communis will outgrow and kill off the typhoid fever bacillus even when at the outset an enormous numerical preponderance is given to the typhoid bacillus over the bacillus coli communis. Again, Wathelet has shown that whereas the bacillus coli communis will flourish in a nutrient medium containing the toxins elaborated by the typhoid fever bacillus, the typhoid fever bacillus will not grow in a nutrient medium containing the toxins elaborated by the bacillus coli communis. If this holds true in every case, and it has seemed * Journal Amer. Med. Assoc., Dec. 14, 1889. page 834. + London Lancet, July-Dee., 1895, page 199. i London Lancet, July-Dee., 1895, pages 196-9. STATE BOARD OF HEALTH—REPORT OF SECRETARY, 1896, to hold true in the few test experiments we have performed, we are evidently in a position to infer on a priori grounds that typhoid fever bacilli will be absent from the intestine whenever, as in the case of typhoid fever, we have to deal with the multiplication of the bacillus coli communis in the intestine. Both a priori reasons and actual observations therefore point to the absence of typhoid fever bacilli fxom the intestinal tract, and therefore the symptoms of typhoid fever cannot be interpreted as a result of the absorption of typhoid toxins from the intestine. They seem to ignore the poison of the bacillus coli communis. We are therefore compelled to seek for a new theory for typhoid fever, and if typhoid fever is not the result of an intestinal intoxication process we must evidently seek to explain it as a result of blood infection. This is, if we understand it aright, the theory of typhoid fever which has recently been put forward by Sanarelli, under the auspices of Metchnikoff. We have to see whether typhoid fever can be explained upon the basis of this theory. And evidently the first thing to be explained in the case of typhoid fever is the turgidity of the spleen and the presence of the typhoid bacilli in the splenic tissue. Now, this turgidity of spleen and this presence of micro-organisms in the splenic tissue is an invariable accompaniment of every septicsemic process. We find it in the case of such blood infections as anthrax in cattle and spirillum fever and malaria in man. And we have the explanation of this phenomenon in the experiments of Werigo which show that the introduction of any foreign particulate matter into the blood invariably results in a deposition of that particulate matter in the spleen (and other internal organs), and in an aggregation of polynuclear white blood corpuscles around the foreign particulate matter, and finally in a process of phagocytosis. Every body who has a rabbit and a little carmine, or any bacterial culture at his disposal, can readily verify these facts for himself. The enlarged spleen and the presence of bacteria there are thus quite in harmony with the theory of a blood infection in typhoid fever. The fact that the white blood corpuscles are diminished* in the circulating blood in typhoid fever is also in harmony with this explanation. We have further in connection with typhoid fever to account for the eruption of pink spots on the skin. These were inex- plicable on the intoxication theory of typhoid fever. They are, however, of the easiest explanation if we make the assumption that typhoid fever is characterized by a blood infection, for here, as in other cases, we may instance the skin eruption in the case of human glanders; the spots evidently correspond to lodgments of the bacteria in the capillaries of the skin. This interpretation of the skin eruption has been borne out in the case of typhoid fever jnst as it has in the case of glanders by the fact that the specific bacteria have been cultivated from the spots. We have been able to confirm this observation in one of the cases of typhoid fever reported below. “ The intestinal symptons of typhoid fever are of somewhat uncertain explanation. Possibly they are to be explained as Sanerelli explains them, as a specific effect of the typhoid fever toxin on the adenoid tissue of the intestine, and of the subsequent invasion of that tissue by the bacillus coli com- munis” * * * “ The occasional presence of typhoid bacilli in the intestine is easily accounted for by assuming that a certain number of the typhoid fever bacilli escape through the intestinal wall into the intestinal contents. “ In addition to the points which have just been touched upon, we may refer to other points which, although they have been comparatively neglected, throw an important light upon the pathological processes which are associated with typhoid fever. The phenomena in point are the presence of so-called 1 miliary lymphomata1 in the kidney and the presence of the typhoid bacilli in the urine. We have no recent opportunity of studying the miliary lymphomata which are describ d as occurring in typhoid fever, but they are probably quite comparable to the miliary lymphomata which are described as occurring in the spleen in cases of spirillum fever, and to the miliary lymphomata which are pro- duced by the injection of fairly resistant bacteria, such as tubercle bacteria into the blood. Such lymphomata correspond to aggregations of the white blood corpuscles around bacteria which have lodged in the capillaries. They are a repetition in small of the aggregations of phagocytic white blood corpuscles which are seen on a far larger scale in the spleen. Lastly, in regard to the presence of typhoid fever bacilli in the urine. Even if typhoid fever bacilli were found in the urine only in occasional cases their presence there would be a strong argument in favor of the theory of a blood infec- tion and against the intestinal intoxication theory. But the argument in favor of the septicaemic theory of typhoid fever becomes irresistible if it can be shown that the typhoid fever bacilli are almost always found in the urine in cases of typhoid fever. With a view of ascertaining this point we have examined the urine in the following typical cases of typhoid fever.” *“ It may be pointed out incidentally here that the paucity of white blood corpuscles in the blood pro- bably stands in some connection with the fact that epistaxis is of frequent occurrence in typhoid fever. This epistaxis, if we may judge from a great many observations which one of us has made of the con- dition of the blood-coagulability, is almost certainly an indication of a diminished blood-coagulability such as can be obtained by the injection of particulate matter into the blood. In an experiment made by one of us the coagulation time of a dog’s blood in the standard capillary tube was reduced from three minutes to fifteen minutes by an injection of carmine particles. THE ETIOLOGY AND PATHOLOGY OF TYPHOID FEYER. The Journal of the American Medical Association summarizes the con- clusions of Drs. Wright and Semple as follows:* “1. It is true that the typhoid bacilli are present in the urine of patients suffering from typhoid fever, and if, as we shall see, typhoid bacilli are generally absent from the feces, it will be evident that it is the urine, and not the feces of patients suffering from typhoid fever which is responsible for the spread of typhoid infection. “2. If typhoid bacilli are constantly present in the urine of typhoid patients it may be possible to diagnose the presence or absence of typhoid fever by undertaking a bacteriologic examination of the urine. “8. If it is true that typhoid bacilli are constantly present in the urine in cases of typhoid fever while they are generally absent from the feces, it will be evident that the conception of typhoid fever upon which the ordinary clinician proceeds is an entirely erroneous one. “4. The working hypothesis regarding this fever in the minds of medi- cal men generally, favoring as it does the notion that this fever is an intestinal intoxication process, should be revised, and substituted for it one that will have regard to the wide range of pathologic appearances, some of which at least fit in well with a hypothesis of blood infection, such as malarial fever in man and anthrax in cattle.” While most of the views expressed by Drs. Wright and Semple seem to me to accord with the facts, a few important discrepancies are noticeable, (1.) From several lines of evidence it is apparent that the infection of the body by typhoid fever is primarily by way of the alimentary canal: therefore, the “assumption that there is a certain leakage of typhoid bacilli from the intestine into the system” appears to be true in fact. This, however, does not negative their assumption that later there may be a “leakage” from the general circulation and the tissues into the intestine. (2.) Inasmuch as the common bacillus of the colon is increased in typhoid fever, and in its life processes produces a poison which when mixed with the product of the typhoid bacillus has increased toxic power,f intestinal antiseptics in typhoid fever may yet be important, notwithstanding the contrary suggestion of Drs. Wright and Semple, so that, although we may come to rely upon the poison of the bacillus coli communis to destroy the typhoid germs, instead of substituting for the intestinal intoxication theory, there may be added to that doctrine the idea of general blood and systemic infection, which seems to be well established by the independent observations of a very great number of investigators. * Jour.

A young gentleman took sick with enteric fever, while visit- ing a neighboring chateau. He had been supplied with milt from this farm, and his female servants who carried the milk were taken sick likewise. Dr. Franz Spaet, Arch, fur Hy- giene, Milnchen and Leipzig, 1893, XVII., p. 306. 120 1893. (!) In this instance Dr. Wepley traced the infection to a creamery which collected milk from a number of farms, at one of which a few cases of enteric fever occurred, infection originally carried from Cork. The milk at these creameries is separated, the cream made into butter, and the skimmed milk returned to farmer, thus causing intimate relation- ship, and the disease may easily become widespread among the users of milk.

Univ. of Virginia 14 14 100 These cases of a typical typhoid fever occurred among the students of the university, all boarding at the same hotel and consuming a particular milk sup- ply from a dairy which is located on the banks of the creek, which receives the sewage from one of the main university sewers. An ignorant negro, who lives 1 mile above the dairy, had typhoid fever during the preceding fall, and his dejecta was thrown on the ground without disinfection. The milkman used creek water to wash the udders of the cows. Dr. Wm. C. Dabney, Med.

A typhoid fever house in close proximity ; dejecta thrown on the ground close to a small dam in the creek, from which a pipe sup- plied a large tank 75 feet below with water for dairy purposes; moreover this polluted water flowed through the cow pasture.

This re- sulted in a cleaning of the well, which was found to be contaminated with a very foul sediment, a dead chicken, and other organic refuse. The season being unusually dry, and the ground water being low, had resulted in concentration of the impuri- ties, and as this well had been used for dairy pur- poses, it was doubtless the source of infection. nished by our friend, Dr. George Lloyd M a grader of Washington, D. C., and Dr. W. F, Elgin, of Montgomery Co., Ala. * 126 Shildon, Durham Co. In a very extensive epidemic of enteric fever a large share in spreading the fever was due to a particular dairy, where cases of typhoid fever existed and the wife, who managed the milk business, also nursed the sick children. There was, moreover, a direct connection between the sewer and the room in which the milk and utensils were kept. Dr. Bruce R. Low, Rep. to the local government board on an outbreak of enteric fever at Shildon, London, April 23,1894. 127 1894 ... Castle Island, Ireland A serious outbreak was traced to a creamery receiv- ing among others the milk from a farm where enteric fever had occurred, and which was handled by a person who also assisted in nursing those suf- fering from the disease. The cream had been sep- erated and the skim distributed in due proportions among the different farms. Brit. Med.
