294 ENZOOTIC DYSENTEEY. 



same condition as the first case. The action of the heart was 

 so violent as to be heard at some distance, and at every beat 

 it seemed to shake the whole frame. She purged an immense 

 quantity of dark liquid, mixed with coagulated blood, &c., 

 but she did not vomit." This cow died. 



Of Case 3 ' Caustic ' says : " I was requested to see a cow 

 belonging to my father; a remarkably large, good framed 

 milking cow, five years old. She appeared well the previous 

 evening; had been turned out to grass in the day time, and 

 was tied up at night, being allowed good hay. I found her 

 lying down, and I could scarcely get her to stand up for a 

 moment. The ears and horns were cold; the pulse weak, 74 

 in number ; the beat of the heart very loud ; the first and 

 third stomachs full and hard. She had not vomited, but 

 had evacuated, with some difficulty, a little dark-coloured 

 pitchy matter. I at once gave no hope of recovery, but 

 being persuaded to try what I could do, I gave her a large 

 dose of linseed oil with the oil of croton, combining a gentle 

 stimulant, but she died five hours after I first saw her/' 



Post-mortem appearances. The epithelium of the three 

 first stomachs is readily detached, and the mucous membrane 

 throughout the stomach and intestinal canal is of a dark red 

 colour, infiltrated, and the seat of erosion. It is, however, 

 in the large intestine that there are usually most marked 

 signs of inflammation, ecchymoses, ulcers, &c. 



Keferring to the cadaveric lesions which occurred in Case 3, 

 above-mentioned, ' Caustic ' says : 



" The rumen and omasum I found filled to repletion with 

 food. The true stomach, and the whole of the intestines^ 

 contained an immense quantity of matter similar to that I 

 have before mentioned; and, strange and incredible as it may 

 appear to those who have never witnessed it, I could pull 

 from the intestines several feet of it without its breaking.
