Instruments. Scalpel, elastic ligature, strong silk 

 thread, strong piece of tape i m. long;, artery and compres- 

 sion forceps. 



Technic. The operation is carried out on the recumbent 

 animal under complete anaesthesia, the upper hind foot 

 being drawn backward or upward or otherwise so fixed as 

 to not obstruct the field of operation. The point of opera- 

 tion is determined by the character of the disease and the 

 object to be attained. It may be made at any point from 

 the glans penis to the attachment of the corpus cavernosum 

 to the ischium. If possible amputate in front of the pre- 

 putial ring. After the penis is drawn out, and the pre- 

 putial region is carefully cleansed with warm water, soap 

 and brush and disinfected, an assistant grasps the organ just 

 behind the preputial ring and holds it firmly. A temporary 

 elastic ligature, T, is then applied above the assistant's 

 hand around the penis, or a piece of tape is looped around 

 it above the hand and is made to serve both as a tourniquet 

 and as a means for holding the penis or it can be grasped 

 in front of the ligature with double tenaculum forceps and 

 held. Insert a catheter into the urethra and push it beyond 

 the elastic ligature or tourniquet. Apply a small cord just 

 behind the glans penis, L, Fig. i, Hate XVII, and then 

 make a triangular incision on the ventral surface of the 

 organ about 4 cm. long by 3 cm. wide, the base of the 

 triangle being forward as shown in Fig. i ; carry this 

 incision through the skin, S, the corpus spongiosum, CS, 

 and along the corpus cavernosum, CC, down to the urethra, 

 U. Disect away the tissues in the triangular area without 

 opening or wounding the urethra and when this has been 

 completed make a longitudinal incision from near the apex 

 of the triangle to its base through the urethral walls to the 

 catheter. Beginning at the commissure insert a series of
