faith m me from previous occasions, consented to have the 
operation performed.

could, although the abdomen was greatly distended by its con¬ 
tents and faeces, stood the animal with her right side against 
the wall, tied her head firmly and placed a plank under her 
abdomen so as to prevent her from lying down during the 
operation and gave her four grains of morphine hypodermically, 
and locally eight per cent, solution of cocaine over the parts to 
be operated upon. After clipping the hair and washing the 
parts with soap and water, and bathing it with a sublimate 
solution, one to a thousand, made a longitudinal incision eight 
inches long, and cutting through the bowel placed an aseptic 
towel on the lower portion of the wound; inserted my hand and 
found the invagination in the anterior portion of the floating 
colon. Bringing the parts on the outside of the abdomen, 
placing bowel-clamps back of the diseased portion, leaving room 
for dissection. Resected the diseased portion carefully and 
antiseptically, laying special stress that no escape of the ingesta 
should take place, by placing several aseptic towels in the 
abdomen, from previous occasions being convinced that some¬ 
thing would be necessary to hold the bowel in its normal shape 
during the stitching or bringing of the parts together, to pre¬ 
vent the escape of the ingesta afcerwards through the wound. 
No doubt you have observed or heard about Murphy’s But¬

is made of glass

used numbers of 
times as long as it 
was made aseptic.
