 is reached, opened barely sufficient to pass over the broad 

 ligament and clip it off. The beginner must always remem-

 tracing tlie uterus from the vagina along its cornua to the 

 Fallopian tube and thence to the ovary in the broad liga-

 Plate XVI. 



Instruments. Spaying knife, suture material. 



Technic. 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 jElank 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 ii.cision from below upward about 

 2 to 3 cm. long, ending above at a point slightly below the 

 external angle of the ilium, the inci.sion extending through 

 the .skin and subcutaneous tissues ; without removing 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 bitch are unique among
