CHAS. SCHMITT. 
drochloric acid was then passed into the anus and closed with 
the hand. In a short time the right and later the left side 
became greatly distended, and the animal strained so much that 
it was difficult to keep the anus closed. After a time me Uand 
was removed and large quantities of carbonic acid gas and faeces 
escaped—and the animal recovered, having thus cured a cow 
of invagination of five days’ standing. But this treatment is 
scarcely recommended by the fact that he afterward found the 
cast-off portion of the bowel in the dung. If invagination had 
really existed, recovery was due less to the treatment than to 
the medicatrix natura. The method may, however, be tried 
when operation is out of the question and other means are 
effectual. 
Dr. Meyer has operated on several cases. His great conten¬ 
tion was after cutting through the bowel, or mesentery, to stop 
the ingesta, and after a section of the parts great difficulty was 
observed in bringing both ends together. Although, after suc¬ 
ceeding in stitching the bowel together, and removing the 
bowel-clamps, great difficulty was caused by the continued pass¬ 
age of the ingesta through this section, and he was somewhat 
embarrassed by his results. 
Degive’s experience is somewhat singular. He prefers to 
open the abdomen and replace the invaginated part if possible, 
and on failing to do so leaves the animal to its fate. 
Dr. Taccoen operated on two cases, from one of which he 
removed ten inches of bowel, but had no bad consequences. 
Thirty-five days later the external wound was healed, and on 
slaughter the incision in the bowel was found to be completely 
cicatrized. In the second case an incurable anusprceternaturalis 
formed, but did not impair the animal’s health. 
Dr. Riedinger treated during 1890 ten cases of invagination 
of the bowel in oxen. Seven animals had to be slaughtered on 
account of the operation being done too late. On the other 
three laparotomy was carried out and the invagination reduced. 
The portion of bowel was cleansed with one per cent, of subli¬ 
mate solution, replaced and the bowel closed with button sutures.
