HOG CHOLERA. 1279 



The intestinal tract is ordinarily the seat of the most severe lesions. 

 In the stomach the fundus or most dependent portion is deeply reddened, 

 often blackish in color, depending on the amount of extravasated blood. 

 Occasionally clots of blood are found forming a coating around the food. 

 In older cases the inflammation may be absent or replaced by isolated 

 ulcers. The duodenum is rarely affected. The jejunum seems to enjoy 

 a still greater imnmnity. The ileum is less exempt from pathological 

 changes which seem to be proportioned to the extent and severity of the 

 lesions found in the adjoining large intestine, which will be first de- 

 scribed."
