The operation in the sow is practically the same as in the 
bitch and cat, remembering that the cornua are long and flexu- 
ous and floating freely among the convolutions of the small 
intestines. After securing the horn one can draw the ovary 
out and remove. 
The operation in yearling heifers and calves is of necessity 
performed through the abdominal walls. The animal is cast 
and secured, the hair clipped from the operating field, the parts 
washed, shaved and thoroughly disinfected ; then an incision is 
made according to the mode of operation selected, some oper¬ 
ating through the flank, while others prefer the linea alba. I 
prefer and shall describe the flank operation. An incision is 
made through the skin and skin muscle midway between the 
external angle of the ilium and the last rib, and then the mus¬ 
cular bundles of the external and internal muscles separated 
consecutively with the scalpel handle or other blunt instru¬ 
ment, and then puncture or rupture the peritoneum large 
enough to admit the hand ; this done, the hand is passed into 
the abdominal cavity, locating one, usually the uppermost cornu, 
and tracing it to the ovary, grasp it, pass the long curved scis¬ 
sors through the wound and cut off the gland, making sure to 
retain the same and bring it to the outside, and repeat the oper¬ 
ation upon the other in the same manner. The incision should 
be sutured with some strong material, linen or silk, and dressed 
antiseptically. Should it be in the season of flies guard against 
the attacks of their larva by accurate suturing and antisepsis.
