with a reddish, gelatinous exudation, the spleen is enlarged ; 

 sometimes there is swelling of the lymphatic glands, and bacilli 

 are found in all the organs. The results found after death in 

 animals are very similar to those found in anthrax and in 

 (Edema malignum. Pigeons do not appear to be susceptible to 

 the influence of the bacilli. 



Trichinosis. — At a recent meeting of the Buffalo Academy of 

 Medicine Frank J. Thornbury, M. D., Buffalo, N. Y., made a 

 preliminary report on five hundred cases of trichinosis in swine 

 observed in his work as Inspector in the Bureau of Animal 

 Industry of the U, S. Department of Agriculture. Special at- 

 tention was given to conditions in the pathology of trichinosis 

 not previously noted, comprising peculiarities of encapsulation, 

 degenerations, calcifications, pigmentations, etc. A large num- 

 ber of photographs and drawings were preseated which illus- 

 trated these conditions, and an extensive exhibit of rare and in- 

 teresting slides under the microscope was given. 



Reference was made to the relative frequency and extent of 

 infection of the different parts examined according to the Gov- 

 ernement system of inspection. These comprise (1) the dia- 

 phram, (2) neck, and (3) loin respectively. The entire number 

 of cases in which trichinae were found in the diaphram were 

 400, in the loin 290, and in the neck 170. The average number 

 of trichinae found in the diaphram in the entire number of cases 

 was 8, in the loin 5, and in the neck 3. In the 500 cases stud- 

 ied all of the three parts were infected in 200 instances, two 

 parts were infected in 136, and one part only was infected in 164 

 cases. The point of predilection for the trichinae, therefore, 

 appears to be the diaphram. This is explained by its close 

 proximity to the digestive tract, from which the trichinas 

 primarly bore. It would appear, also, that the tenderloin is 

 not a preferred article of diet, this comprising as it does the 

 psoas muscles. Where the hogs were extensively infected the 

 trichinae were also found in the hams, shoulders, sides, and, in 

 fact, in almost every part of the carcass. He has also studied 

 the subject of trichinosis in tlie human, with the following 

 results: Of twenty-one subjects examined in the dissecting- 

 room in the University of Buffalo, trichinae were found in 

 the muscles of three. The muscles principally affected were
