 DISEASES OF THE GENERATIVE ORGANS. 145 



AVARTS ON THE PENIS. 



These are best removed by seizing them between the thumb and 

 forefinger and twisting them off. Or they may be cut off with 

 scissors and the roots cauterized with nitrate of silver. 



DEGENERATION OF PENIS (PAPILLOMA, OR EPITHELIOMA). 



The penis of the horse is subject to great cauliflower-like 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 become diseased and indurated. The operation, which 

 should be performed by a veterinary surgeon, consists in cutting 

 through the organ from its upper to its lower aspect, twisting or 

 tying 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 thighs of the mare which it has failed to enter, the penis may 

 become 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 suspended 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. The yard hangs from the 

 sheath, flaccid, pendulous, and often cold. The passage 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 system should 

 be invigorated by nourishing diet, while 30-grain doses of nux vomica 

 are given twice a day. Finally, a wfeak 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 successful. 



SELF-ABUSE, OR MASTURBATION. 



Some stallions acquire this vicious habit, stimulating the sexual 

 instinct to the discharge of semen by rubbing the penis against the 

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