lesions, and more or less general throughout the body. These 
are the lesions usually found in post-mortem examinations when 
the local lesion, or rather localization of the disease, is on the 
digestive tract. In 1872, in a communication to the Soc. Cent, 
de Med. Vet., Prof. Trasbot pointed out that in some very rare 
instances small , gangrenous , superficial sloughs were found on 
the surface of the intestinal mucous membrane; he found that 
these sloughs were confined to the superficial layers of the 
mucous membrane, that there were some tissues found in the 
small intestine, but were not frequent in the large colon. As he 
says, these sloughs may assume the appearance of genuind 
ulceration, but were entirely different from the ulceration of 
typhoid fever in man. When the lungs become the seat of the 
localization the complication is either pneumonia or pleurisy, 
sometimes both. A second invasion of the lung tissue 111 these 
cases is frequently seen, the animals then die rapidly of asphyxia, 
which the post-mortem will show, while at the same time gan¬ 
grenous complications may be found. Prof. Trasbot has described 
this lesion as an oedematous pneumonia, and his description 
of these pathological changes are certainly far more lucid and 
comprehensive than that of any other writer of my acquaintance, 
and from which we obtain these facts: 
“ Ordinarily the pneumonia is more or less restricted, its out¬ 
lines not horizontally marked as in free inflammation. At the 
“lower part there is almost always some lesions in one of the 
“lungs, sometimes in both, for exclusive localization in one lung 
“is a more rare condition than in sporadic pneumonia. In typhoid 
“fever there is found side by side veins of tissue obstructed by 
“inflammatory transudation, and portion which have remained 
“permeable to air. When the lungs are cut, a very maiked infil- 
“ tration is found in places where the pneumonia did not yet exist. 
“ There, as everywhere else, is a stagnation of blood, bringing on 
“diffusion of the serum in the peripheric tissues, and especially 
“in the connective tissue spaces, which enlarge in volume. Theie 
“is nevertheless genuine pneumonia with exudation into the 
“interior of the acini. At the points where the inflammation is
