the horse was again straining, did not press my examination. A 
diagnosis of spasmodic colic, with laceration of the rectum from 
the maladministration of injections. 
A very grave prognosis was given. 
A six drachm dose of chloral was given, and orders to give 
two ounces of tincture opii. with one ounce of sul. ether in a 
couple of hours, if the horse did not remain quiet, were left with 
the coachman. 
About seven o’clock I saw the horse again, and found him 
much quieter from'the effects of the opiate, but there was still a 
slight discharge of blood from the anus. The administration of 
opium and ether through the night was directed, and the owner 
told that the horse would not recover. 
He was seen again the next morning, when he was found 
almost pulseless, covered with cold perspiration, and a temperature 
of nearly 105°. The rectum was swollen to such an extent that 
the hand could not be introduced, nor was it desirable to do so. 
Word was left that the horse could live but a very short time, 
and a post mortom was requested. The animal lived about half 
an hour after he was seen. On being informed that he had been 
taken to the offal dock, I went there and made an examination. 
I found on exposing the contents of the abdomen, that there 
was some peritonitis, with but little fluid; that the large intestine 
was somewhat inflamed; having removed the large intestine, the 
floor of the pelvis was cut through so as to expose the rectum, 
together with the small colon; a circular incision was made 
around the anus, and the rectum, together with a portion of the 
floating colon, was removed. 
No foeces were found in either the rectum or in the small 
colon. 
The internal surface of the rectum was intensely swollen and 
congested and the small colon to a lesser degree; but at the an¬ 
terior extremity, at the termination of the floating colon and ex¬ 
tending into that portion of the intestine, the rectum was com¬ 
pletely perforated, except about an inch in the centre, and this 
portion was nearly torn through. The hand could be passed from 
the intestine to the outside with ease. The edges of the wound
