Anatomy — The anatomy of the internal and external genital organs of 

 the heifer is the same a.s that of the cow. (See page l.'io.) The flank re- 

 gion possesses a well defined triangle, through the center of which the ab- 

 dominal incision is made. The tissues penetrated by this incision are as 

 follows : skin, subcutaneous connective tissue, fascia, external and inter- 

 nal ol)li(iue abdominal muscles and the peritoneum.

Sterilization of Instruments and Cleansing Hands of Operator — Same 

 as for cow spaying. (See page 158.) If the operator is right-handed, it is 

 best to invade the left Hank. If left-handed, the right flank should be 

 selected. 



Operative Technic — 1. Clip the hair from the site of operation. 



2. Wash the parts with soap and warm water, using a scrub brush. 

 Special care should be taken to remove all loose hair from the field, and 

 sponge with antiseptic solution. As a further precaution against septic in- 

 fection it is well to paint the skin with tincture of iodin.
