INTUS-SUSCEPTION IN THE HOUSE. 
rm 
total blindness, gave evident intimation of a speedy termination 
in death, and which occurred about eleven o’clock on the same 
morning. 
On opening the animal, I was surprised not to observe that 
discolouration of the intestines usually attending a case of ente- 
ritis — the disease which I considered the patient had been labour- 
ing under : the only deviation from a healthy appearance was a 
slight vascularity of the mucous membrane shining through the 
peritoneal and muscular coats of the large and small intestines, 
more particularly of the csecum. Having examined the liver, 
kidnies, bladder, and stomach, all of which were healthy, ex- 
cepting a little thickening of the villous coat of the last viscus, 
I was for a moment at a loss to account for death ; but on farther 
inspection, the cause soon presented itself, for after tracing the 
small intestines, I found a considerable portion of the ileum pro- 
truding into the csecum. To have a proper view of this pheno- 
menon, I had the csecum longitudinally opened, which presented 
the intus-susception lying in a curved position within its base, 
the end pointing towards the opening of the colon (as shewn in 
the accompanying sketch). It had a very singular appearance, 
was of a dark gangrenous colour, much thickened with excoria- 
tions of the villous membrane, and pulpy, as if the csecum, de- 
termined not to be interrupted in its important digestive function, 
had commenced its action upon it. 
I removed the parts, and found that a portion of the small 
intestine, 20 inches in length, was included within another por- 
tion, and this intus-susception was lying within the csecum, 
making a complex or double enclosure ; and that the valvular 
structure, or band of muscular fibre of the valvula coli, had 
formed a complete sphincter, so firmly contracted, that it was a 
matter of impossibility for any thing to proceed into the csecum, or 
the intus-suscepted part to return ; and thus, of course, render- 
ing whatever means might have been adopted for its recovery 
perfectly useless ; for, even if the application of mechanical means 
had been practicable, it would have been impossible to have 
properly replaced the intestine. 
The symptoms differed little from enteritis : the raising of the 
haunches and kicking out, instead of striking the belly with its 
hind legs — the great prostration of strength, with total blindness 
a short time before death — and the peculiar attitudes and expres- 
sions of agony which attended the last struggles of the pony, 
were the most worthy of remark ; but as this is the only instance 
in which I have had an opportunity of observing the progress 
and termination of this disease, I cannot recommend these pecu- 
liarities as a diagnosis which can be depended upon.
