REPORTS OF CASES. 
introduction of my hand into the rectum caused acute pains, 
although it was quite empty. I made a diagnosis of strangulation 
of the lower bowels, after hearing the following history: During 
the last six months he has had as many attacks, which would last 
from three to ten minutes, during which time he would tremble 
and sweat very profusely, recover, and apparently be all right for 
a month or so. Some of these would come on while out driving, 
but as a general thing immediately after watering. 
After an hour from the administration of the opiate he began 
his former antics. I now let him inhale chloroform until he went 
down completely under its influence. I kept him in this condition 
for over an hour with hopes of reducing the strangulation, but to 
no effect. I now took into consideration the low rectal tempera¬ 
ture, the irritation caused by rectal examination, pulse growing 
weaker, membranes becoming more injected, anxious expression 
of countenance and persistence of the symptoms, and concluded 
that any treatment other than opiates would only hasten the death 
of the animal. Therefore I gave subcutaneous injections of 
morphia as the symptoms required. After eight hours he became 
very tympanatic, which I relieved with the trocar. Gas came 
away dry, showing no inflammation of the large intestines. He 
now urinated freely. I now left him, telling the groom to call 
me if he swelled again, but he went to sleep, and I found my 
patient dead the next morning. 
Post-mortem .—Yerv tympanitic; no inflammation of large 
intestines; the small colon all rolled up in a mass about the origin 
of the posterior mesenteric artery. This I severed and held up, 
and it made three complete turns before untwisting: presented 
very little inflammation in some of its parts, while other parts 
were undergoing gangrene for six inches in places. The reason 
of this patchiness was due to blood supply being shut off by 
strangulation.
