feed, and continued to be more so until it was killed, October 7th 
temperature for several days about 104° Falir. October 3d it be 
gan to emaciate and had a distressing cough, with yellowish dis 
charges from the nostrils and a pultaceous discharge from the rec 
turn. Being very sick on the 7th of October, and liable to die 
before next morning, it was considered best to kill the animal 
which was done. No staining of the skin was observed (it was i 
very black pig). (The animal was inoculated, as described above 
but in some few cases where we have resorted to sub-cutaneou.- 
inoculations we have had excessive tumefaction and heat, with disi 
coloration of the skin.) On cutting through the skin of this ani 
mal the blood which flowed from the cut vessels was of a darl 
blue red color, and soon coagulated and became red on contac 1 
with the air. The large intestine was agglutinated and covered 
with a thick, floculent lymph. The superficial inguinal and mes 
enteric lymphatic glands were swollen and reddened, and the mes 
enteric veins injected; bladder full. The small intestines pre 
sented a diffused red color; on opening, the mucosa was foun< 
swollen with diffuse capillary redness; Peyer’s patches swollen 
with an occasional dark red spot in their midst; contents of in 
testines were fluid. The mucosa of the large intestine was reJ 
and swollen; also with dark red spots of various sizes dispersed 
through it: ileocaecal (or valve of Bauhini) intensely swoller) 
Throughout the large intestine were numerous ulcerations fror! 
the size of a pea to a ten cent piece, covered with a yellow, case 
ous mass; spleen enlarged, but not disintegrated; liver enlarged 
edges rounded ; the acini distended and of a yellowish red colol 
(degeneratio adiposa). The interstitial tissue was swollen, and th 
bile ducts somewhat distended with bile; kidneys, cortical sul 
stance, anaemic, and of a yellowish grey red color; medullary sal 
stance, red, and the vasa recti injected; slight effusion into th 
pleural cavity, but the plurae non-adherent. The pericardiui 
contained about two tablespoonfuls of a straw-colored fluid; tl 
myocardium was of a yellowish gray red color, anaemic, and a fe 
petechae on the endocardium. In the lungs were small centres c 
lobular hepatization. The bronchial tubes and trachea containe 
a purulent, viscid effusion, the mucosa being swollen and injected
