THROMBOSIS OF THE GREAT MESENTERIC ARTERY. 
THROMBOSIS (CONTAINING PARASITES) OF THE 
GREAT MESENTERIC ARTERY, 
From the introductory remarks of the highly interesting cases 
reported in the first article of the fourth volume of our profes¬ 
sional organ, I infer that citations belonging to the sphere of the 
same category would not be objectionable. Therefore I take the 
liberty to communicate one of my earliest observations of an 
analogous nature. 
The memorandum is dated September 30, 1857. I had no 
idea then of making any further use of it than to compare it at 
some future time with similar occurrences, for which I have been 
looking ever since in vain. 
The subject was a nine-year-old brown mare, sixteen hands 
high, and in tolerably good condition. I was informed that dur¬

October 1—7 A. M., condition unchanged ; in the evening ap¬ 
parently recovered. During the night the patient discharged 
considerable soft, undigested feces. 
October 2—In the morning, when the owner appeared, the 
mare neighed lustily; water then was given her, which she 
drank freely. After eating about one-third of her food, she com¬ 
menced looking back to her sides, lying down and rolling about; 
this uneasy spell passed off in a short time, and at noon she ate 
some food with apparent relish. At 4 P. M. the pains reappear¬ 
ed, attended with profuse perspiration ; the dorsal position is now 
the preferred one. At 8 P. M. she began sitting on her
