. Diseases of cattle, sheep, goats and swine. Veterinary medicine. CASTRATION. 767 Third stage. Ablation of the ovaries or of the ovaries and horns of the uterus. Fourth stage. Suture of the wound. The tissues are divided layer by layer. The skin is formed into a longitudinal fold and divided in a vertical direction, and the sub- jacent muscular layers are then divided with the bistoury. The tissues are next broken through layer by layer with the index finger until the parietal peritoneum is reached. This membrane is then fissured, or at least scraped with the nail, and perforated wdth a sudden sharp thrust of the index finger. This practice, however, has the disadvantage of sometimes causing the parietal peritoneum to strip away from the wall of the abdomen, which greatly increases the difficulties of opera- tion. It is better, therefore, to grasp the peri- toneum wdth a small pair of forceps, draw it out- wards, and secure it so as to puncture it with more certainty. When experience has been ac- quired this precaution will be unnecessary. The incision being made and the finger in- troduced into the abdomen, the operator, who kneels against the animal's back, searches for the ovaries with his index finger. The upper ovary of the side in which the incision has been made will be found immediately in contact with the parietal peritoneum, and the operator must take care not to displace it by untimely or care- less manipulation, which may thrust it away among the loops of intestine. The finger being doubled up in the form of a hook, the ovary is seized and drawn out. Sometimes it may be easier to withdraw the uterine horn, leaving the search for the ovary until a little later. The first ovary having been discovered, its pedicle is seized between the left_ thumb and index finger or the jaws of pressure forceps, and then the search is continued for that of the opposite side. In young sows the horn of the uterus may be followed up from its extremity (ovarian extremity) tow
