entiate it. This will be discussed while dealing with the in- 

 fections of the genitalia of horses. 



The handling of malignant disease of prepuce, sheath, 

 and penis of the breeding stallion calls for prompt and 

 skillful measures. The early ablation of the neoplasm is 

 the only course known which offers hope . Even then the 

 hope is based upon the complete extirpation of the growth, 

 in such a manner as not to interfere with the power to copu- 

 late. When involving the sheath only, complete removal 

 may be possible, but there is danger of such deformation 

 of the parts as will cause faulty direction of the erected 

 penis. If the prepuce is involved, a greater danger faces 

 the surgeon because adhesions between the direct and re- 

 curved portions may bar the protrusion of the penis. 



When the penis itself is involved, the amputation of a 

 part or all of the glans does not disable the animal, but if 

 the amputation needs to be on the proximal side of the pre- 

 putial ring, the breeding capacity of the animal is probably 

 ruined. I find no conclusive data on this point, but it has 

 been proven clinically that the glans can be amputated with- 

 out serious interference. In the present state of our knowl- 

 edge, when the malignant growth has extended beyond the 

 glans into the penial body, no hope should be given of re- 

 storing the breeding powers. In a gelding I have seen the 

 cancerous growth involving the entire penis from the glans 

 to the attachments of the crura to the ischial tuberosities. 



2. Amputation of the Penis 



Almost, if not all cases of malignant tumors of the glans 

 penis should be handled by the amputation of a portion or 

 all of the glans. The amputation should be carried out by 

 the following technic, which affords ample security against 

 urethral stricture and provides a tapering stump which can 

 most readily enter the vulva in copulation. The amputation 

 of the penis of the stallion affords a technic equally applica- 

 ble to that of other species.
