DISEASES OF THE MALE ORGANS OF GENERATION. 301 



particularly in geldings. It is due to injury of some kind, and 

 may be produced from the habit of not properly protruding the 

 penis while urinating. 



Treatment. — Foment the parts with warm water and scarify. 

 Give internally potassium nitrate, one-half ounce; sweet spirits of 

 nitre, one ounce. In some cases it may be necessary to enlarge 

 the prepuce or remove warts. 



PARAPHYMOSIS. 



The penis protrudes in paraphymosis, and cannot be drawn 

 within the sheath. It may arise from a weakened condition of 

 the penis, or from direct injury, too frequent coition, etc. 



Treatment. — If it results from paralysis, amputation is the 

 only remedy. When it is caused by debility or injury, it should 

 be treated with a view of returning it. If there is much swelling, 

 it should be scarified and placed in a suspensory bandage. Apply 

 fomentations, as cold water. It becomes necessary in some cases 

 to puncture the sheath to prevent strangulating the penis. 



AMPUTATION OF THE PENIS. 



It becomes necessary in some instances to amputate the penis. 

 This operation will require the employment of a surgeon. The 

 animal should be cast and chloroform administered. A catheter 

 should be introduced into the urethra and held in position by 

 passing a ligature around the penis an inch above the intended 

 incision. The penis should now be removed by a bold incision 

 and the arteries ligatured. The ecraseur is a very good instru- 

 ment for removing the penis. The catheter should be allowed to 

 remain in the urethra until it partly heals, in order to prevent 

 closing of the urethra by cicatrization. The wound should be 

 dressed with the zinc, lead, acid lotion. Various kinds of 

 growths occur in connection with the penis. They should be 

 removed and the parts touched with a pencil of nitrate of silver.
