OPEKATIVE SURGERY. 295 



secure the other ovary, the possession of the first materially as- 

 sisting in finding its fellow. The ovaries are twisted off to pre- 

 vent hemorrhage, which would be liable to occur if the parts 

 were directly cut with the knife. The horns of the uterus are 

 then returned to the abdominal cavity and the lips of the incision 

 brought together by sutures. It is well to take one deep suture 

 through the skin, abdominal walls and peritoneum, and two 

 superficial ones through the skin, just bringing the edges of the 

 cuticle in apposition. The sutures should not bring the edges 

 of the wound tightly together, as the inflammation which al- 

 ways results would tend to tear out the stitches, which would be 

 followed by serious if not fatal results. 



The after-treatment consists in dressing the seat of the oper- 

 ation with pine tar or some such agent to keep the wound in an 

 aseptic condition and prevent attacks of the fly. 



■pi^cturcs. 



A fracture of a bone is the solution of its continuity. A 

 simple fracture is where the bone is broken without injury to the 

 soft tissues covering it. 



A compound fracture is where an open wound exists which 

 connects with the broken bone. 



Where the bone is shattered into fine fragments, the frac- 

 ture is said to be comminuted, and complicated, when together 

 with the broken bone, severe injury to the adjacent tissues, or 

 deep-seated bnusing of the parts also exists. 



Symptoms. 



Great lameness, inability to bear weight on the limb, which 

 hangs limp, the animal being unable to exert any control over 

 the affected member. Manipulation of the part reveals crepitus, 

 the sound made by the broken ends of the bones coming in con- 

 tact with each other. The animal exhibits great pain when the 

 parts are being handled.
