PRACTICAL METHOD OF SECURING A HOG. 
operator should be seated upon a low stool and have the pig- 
laid upon the right side with its posterior extremity to his left, 
and its back toward him ; he then places his left foot upon its 
neck and his left under the right flank of the pig; and his as¬ 
sistant should draw the hind legs backward, which brings the 
back of the animal against his left leg and stretches the ab¬ 
dominal wall. 
Technique of the Operation .—The first step to be taken in 
the operation is to shave the hair (bristle—this can be done 
with the spaying knife, Fig. 33-A); and next, wash the field 
where the incision is to be made with an antiseptic solution, 
following by making an incision in line with the fibres of the 
oblique muscles, near the external angle of the ilium and as 
deep as the peritoneum. Another method of opening the abdo¬ 
men is to incise the skin and pierce the muscles and peritoneum 
with the forefinger of the right hand. This is a method 
adopted by many successful operators, and to facilitate the pro¬ 
cedure, a small superficial incision is made into the muscular 
coat, and the forefinger of the right hand forced through it 
and the peritoneum with a short, forcible, rotatory motion ; the 
opening is then enlarged by inserting the forefinger of the left 
hand and tearing the muscular coat and peritoneum, making 
the internal opening larger than the external one. The next 
step is to locate the ovaries and bring them out through the 
opening made in the abdominal wall; this is done by inserting 
the right forefinger into the abdominal cavity, following the
