MORBID ANATOMY 143 
involved.’ The mucous membrane of the two portions 
of intestine first mentioned may be found in a dry, cor- 
rugated condition, the ridges being highly inflamed and 
infiltrated with hemorrhages, very similar to the condi- 
tion seen in swine fever and rinderpest. 
Intestines Generally—Streaks of intense congestion 
may also be observed in other parts of the small or 
large intestine, but in most cases to a lesser extent. 
The entire intestinal mucous membrane is very swollen, 
tender, and pale, and the bowel lumen may be full 
of a thick, creamy mucus. If there are scattered 
hemorrhages or ulcers, this material will be tinted a 
rosy pink, and, rarely, may be of a blood-red colour 
or contain pure blood. Feeces are usually absent. No 
change is noticed as a rule in the Peyer's patches, 
though they may be cedematous. 
Anus.—I have frequently known the rectum and anus 
to be intensely inflamed, in which case attention is 
always attracted to the condition in life, when attempting 
to pass the thermometer. 
Surgical Conditions.—Surgical conditions such as in- 
tussusception and prolapse of the rectum are infrequent, 
but when they occur they are often a prelude to a fatal 
termination. 
Stomach.—The stomach, although irritable during the 
animal’s life, is found on post-mortem to be very little 
changed. Sometimes, however, the gastric mucosa is 
slightly injected and swollen, especially towards the 
pyloric extremity. The corrugation or contraction, 
occasionally noticed, of the mucous membrane of the 
stomach and intestines is a condition consequent upon 
generalised emaciation brought about by sustained and 
profuse purgation. 
Abdominal Lymphatic Glands.—Occasionally, though 
rarely, suppuration may be observed in one or other of
