me to operate upon her, stating, I would only charge for her 
keep, and at last he gave me his consent. On the 16th of 
July she was cast for operation, and in the presence of Mr. 
G. T. Brown, Veterinary Surgeon, who kindly assisted me, I 
dissected away some considerable portion of mucous mem- 
brane and effused matter, taking up some vessels which bled 
pretty freely, as they interfered with my dissection. The 
weight of the mass when excised was about lib. 8oz.; this 
was dissected away from the other structures, leaving the 
muscular and peritoneal coats of the intestine free from the 
knife. I had also to scarify some additional portion of 
mucous folds of that part of the rectum forming the sphincter- 
ani, which readily returned as soon as the mare was allowed 
to rise. She was put upon the same diet as before ; clysters 
of tepid water was administered about three times a day. No 
medicine was given either before or after the operation, it 
being purely a surgical case. The operation did not appear 
to interfere with her general health, but she ate and drank 
well, and passed her faeces regularly when assisted by the 
enema, which was made use of for about seven or eight days; 
after this period she passed her dung naturally, and in 
about a fortnight from the time of operating she was dis- 
charged, the owner stating he should use her as his hack.

PROLAPSUS ANI. 
By J. D. Gregory, M.R.C.V.S., Bideford. 
Dear Sir, — The case of Prolapsus Ani, narrated by Mr. 
Dycer in the August number of The Veterinarian , is of itself 
an interesting one, and the operation, I believe, somewhat 
rare, at least if one may judge from so few being recorded. 
A vast amount of difficulty frequently arises in the treatment 
of these cases ; not so much in the reduction of the prolapsus 
as in the retention of the parts after, from the great straining 
and irritation that follows, and the impracticability of applying 
and retaining a truss ; for, unlike prolapsus vaginae, we cannot 
adapt it to allow of the passage of the excrement. 
I have had to encounter these difficulties, and have been 
obliged, in the end, to have recourse to the knife ; and really, 
as far as I can judge from my experience of the matter, I 
should not deem it, with proper management in the after- 
treatment, a dangerous operation. I have very many times
