For a similar reason the passing of the silk sutures should be preceded by careful dis- FiG. 304. infection of the operative wound, and free wash- ing of the parts with boiled water. The operation is concluded by bringing the skin together with a few silk sutures and inserting a strip of iodoform gauze into the lower portion of the wound, to serve as a drain. LAPAROTOMY. Laparotomy is comparatively seldom performed on animals of the bovine species, though it may become necessary in dealing with cases of hernia, uterine torsion (where direct taxis is called for), Cesarean section, invagination or strangulation of the intestine, and under a few other exceptional circumstances. If simple exploration is aimed at, the- operation is most con- veniently performed from the right flank with the animal in a stand- ing position, but should a prolonged operation be contemplated the animal should be cast. The incision varies in length, according to circumstances, from 8 to 16 inches, and, like that in gastrotom}^, should correspond in direction with the fibres of the small oblique abdominal muscle; the seat of operation should previously be washed, shaved, and disinfected. The operation comprises the following stages :— First stage. Incision of the skin. Second stage. Incision through the muscles and peritoneum. Third stage. Exploration, inspection, palpation, extraction or ablatio
