576 RUPTURE OF THE COLON, &C. OF A HORSE. 
Timid men will say that inflammation of the vein will ensue. 
We can only say, that, in all the numerous experiments of this kind 
which we have made before the veterinary pupils, we have never 
seen any injurious effect produced on the vein. We have even in¬ 
jected twenty grains of corrosive sublimate into the vein, without 
injury to the vessel, although the animal was destroyed by the 
poison.

RUPTURE OF THE COLON, AND PERFORATION 
OF THE BLADDER OF A HORSE. 
By Professor Dupuy. 
I ASSISTED at the post-mortem examination of a horse ten 
years old, and which presented some very remarkable lesions. 
At the opening of the chest, a quantity of gas was disen¬ 
gaged, which had an odour similar to that yielded by the con¬ 
tents of the colon. 
The lungs had no great disease, but exhibited appearances 
of some former inffammatory affection. 
The abdomen was distended with fetid gas, and contained 
at least two bucketsfull of a reddish ffuid. Portions of excre- 
mentitial matter were found about the rectum and the bladder, 
and at the bottom of the pelvic cavity. They had escaped 
through a rent in the cseco-gastric portion of the colon, near 
the stomach. This last viscus seemed in a manner to close the 
rupture of the intestine, and which did not appear to be of long 
standing. It seemed as if the stomach, pressing against the 
opening, suffered only the ffuid contents of the colon to escape, 
and retained the solid portions. There was also a rupture of the 
lower part of the muscular substance of the diaphragm, and the 
diaphragmatic surface of the liver adhered to the edges of this 
opening. 
The most remarkable lesion, however, and what we had never 
seen before, was a perforation at the fundus of the urinary 
bladder ; and not only around, but within the bladder, were ex- 
crementitious matters, both solid and liquid. This accounted 
for what had been observed during the life of the animal, that 
fecal matter, such as is usually found both in the caecum and 
the colon, was discharged through the urethra. 
Before the opening of the horse, the proprietor had shewn 
us on the litter, and on the walls of the stable, matter analo¬ 
gous to that which we had usually seen in the colon of the 
horse; and we confess that we were then unable to account
