OVARIOTOMY IN THE BITCH. 



the instrument introduced along the arm and when the 

 ovary is reached, apply the scissors or ecraseur and cut or 

 crush it off. The beginner must always remember that the 

 positive means for identifying the ovaries is by tracing the 

 uterus from the vagina along its cornua to the oviduct and 

 thence to the organ in the broad ligament. Cleanse the 

 wound and close the skin incision with continuous sutures.

Techic. Confine the animal in lateral recumbency, 

 preferably upon the right side for a right handed operator, 

 the head somewhat depressed, the limbs extended and the 

 body well stretched. Clip, shave and disinfect a sufficient 

 area in the exposed flank at a point just anterior to and be- 

 neath the external angle of the ilium. With one hand grasp 

 the skin fold of the flank and render the skin of the region 

 tense, while with the other holding the spaying knife like a 

 pen make at first a drawing incision from below upward 

 about 2 to 3 cm. long, ending above at a point slightly be- 

 low the external angle of the ilium, the incision extending 

 through the skin and subcutaneous tissues ; without remov- 

 ing the knife from the wound elevate the handle and with 

 a quick thrust make a stab wound extending through the 

 external and internal oblique muscles and peritoneum at a 

 single cut. The operator can determine when the peritoneal 

 cavity has been entered by the disappearance of resistance. 



Introduce an index finger into the peritoneal cavity, and 

 as soon as this has been entered follow directly along the 

 peritoneum upward and backward toward the angle of the 

 ilium where the uterine cornua lie covered over by the 

 broad ligament. The internal generative organs of the
