PARALYSIS AND INJURIES OF THE PENTS.

To lessen the size of the glans and thus facilitate its return, the elastic 
bandage may be used. The parts are cleansed, several turns of the 
bandage applied to the glans, and left in position for a few minutes. In 
very severe swellings this may need to be repeated two or three times. 
The glans is then either drawn back or, after being laved with cold water, 
may be returned to the prepuce. This method can be recommended. 
In case the preputial swelling still persists, benefit sometimes results 
from scarification and bathing with such astringents as solution of alum 
or acetate of lead. Needless to say, a suspensory bandage must be worn 
during massage treatment. Failing improvement by any of these methods, 
a portion of the prepuce may be amputated ; this operation has repeatedly 
been performed with the best results. The animal is placed on its back, 
the penis drawn forwards as far as possible, the prepuce cleansed, and 
the preputial swelling isolated by multiple silk ligatures in the manner 
usual in ruptures and new growths ; the swelling itself is then removed 
with knife or scissors. Haase and others have frequently seen the best 
results from this treatment; the penis remained in position, and the 
inflammation consequent on operation was so slight as to require no 
treatment. 
In paralysis of the penis, massage of the retractor penis muscle between 
the anus and scrotum maybe tried; injections of veratrin, strychnine, 
or similar nerve stimulants might possibly prove useful. The paralysed 
penis is shielded from external injury by applying a suspensory bandage. 
In case of need, it can be amputated. 
In the horse, injuries to the penis are most frequently caused during 
prolapsus by accidental blows, as with the whip. Extensive wounds 
are sometimes caused in stallions during coitus. In bulls, injuries may 
likewise be caused by the penis failing to enter the vagina and striking 
against the ischia of the cow. In such cases laceration sometimes takes 
place, the corpora cavernosa are ruptured, bleeding occurs, and marked 
bending and distortion ensue ; the condition has also been seen in the 
horse. Similar injuries have also been caused by ignorant castrators 
applying clams to the penis, instead of the testicle. Lambert and 
Robert report such cases, in one of which the testicle lay in the abdomen. 
As the horse suffered from colic on the following night, and made fruit¬ 
less efforts to pass urine, the clams were removed, and recovery occurred, 
but amputation of the penis was found necessary. In dogs, injuries of 
the penis are caused by bites and violently separating the animals during 
coitus. 
The first serious symptom which occurs is difficulty in urination. 
Either the injury itself or the inflammatory swelling consequent on it 
compresses or displaces the urethra and produces obstruction. Such 
injuries sometimes produce cicatricial strictures. Lacerations of the
