WARTS ON THE PENIS. 



These are best removed by seizing them between the thumb and fore- 

 finger and twisting them off. Or they may be cut off Avith scissors and 

 the roots cauterized with nitrate of silver, 



DEGENERATION OF PENIS — PAPILLOMA, EPITHELIOMA. 



The penis of the horse is subject to great cauliflower-lilie growths on 

 its free end, which extend back into the substance of the organ, obstruct 

 the passage of urine, and cause very fetid discharges. The only resort 

 is to cut them off, together with whatever portion of the penis has be- 

 come diseased and indurated. The operation, which should be per- 

 formed by a veterinary surgeon, consists in cutting through the organ 

 from its upper to its lower aspect, twisting or t3ing the two dorsal 

 arteries and leaving the urethra longer by half an inch to 1 inch than 

 the adjacent structures. 



EXTRAVASATION OF BLOOD IN THE PENIS. 



As the result of kicks, blows, or of forcible striking of the yard on 

 the tliighs of the mare which it has failed to enter, the penis may be- 

 come the seat of effusion of blood from one or more ruptured blood- 

 vessels. This gives rise to a more or less extensive swelling on one or 

 more sides, followed by some heat and inflammation, and on recovery a 

 serious curving of the organ. The treatment in the early stages may 

 be the application of lotions, of alum, or other astringents, to limit the 

 amount of effusion and favor absorption. The penis should be sus- 

 pended in a sling. 



PARALYSIS OF THE PENIS. 



This results from blows and other injuries, and also in some cases 

 from too frequent and exhausting service. Tiie yard hangs from the 

 sheath, flaccid, pendulous, and often cold. The i^assage of urine occurs 

 with lessened force, and especially without the final jets. In cases of 

 local injury the inflammation should first be subdued by astringent and 

 emollient lotions, and in all cases the syst^ should be invigorated by 

 nourishing diet, while 30-grain doses of nux vomica are given twice a 

 day. Finally, a weak current of electricity sent through the penis from 

 just beneath the anus to the free portion of the yard, continued for ten 

 or fifteen minutes and repeated daily, may prove successfal. 



SELF-ABUSE — MASTURBATION. 



Some stallions acquire this vicious habit, stimulating the sexual in- 

 stinct to the discharge of semen, by rubbing the penis against the belly 

 or between the fore limbs. The only remedy is a mechanical one, the 

 fixing of a net under the penis in such fashion as will prevent the ex- 

 tension of the penis, or so jyvick the organ as to compel the animal to 

 desist through pain.
