DISEASES OE THE GENERATIVE ORGANS. 153 



Treatment— They may be twisted off with the thumb and fore- 

 finger or cut off with a pair of scissors, and the seat burned with a 

 pencil of lunar caustic. To get hold of the penis in the bull, bring him 

 up to a cow. In the ox it will be necessary to push it out by manip- 

 ulation through the sheath. In difficult cases the narrow opening of 

 the sheath may be slit open. 



WOUNDS OP THE PENIS. 



The most common wounds are those sustained by blows of horns, 

 sticks, etc. The blood vessels and sacs are ruptured to a greater or 

 less extent and considerable swellings filled with coagulated blood 

 and inflammatory products occur, leading to distortion of the organ, 

 and it may be to the impossibility of protruding it. 



Treatment. — A lotion of a dram of alum in a quart of water may be 

 applied (injected into the sheath, if necessary), and a large sponge 

 constantly irrigated by a stream of cold water may be kept applied by 

 means of a surcingle to the outer side of the sheath. Incisions are 

 rarely applicable to an organ of this kind, but in case of the existence 

 of an extensive clot which is unlikely to be absorbed the lancet may 

 be resorted to. If the injury leads to paralysis of the penis and hang- 

 ing out of its sheath, it should be supported in a sling and astringents 

 used freely until inflammation subsides. Then the restoration of 

 power may be sought by a blister between the thighs, by the use of 

 electricity, or by the careful use of nerve stinralants, such as strychnia 

 (2 grains daily). 



ULCERS ON THE PENIS.. 



Sores on the penis of the bull may result from gravel or sebaceous 

 masses in the sheath or from having served a cow having leucorrhea. 



Treatment. — These may be treated by frequent injections into the 

 sheath of a lotion made with 1 dram sugar of lead, 60 drops carbolic 

 acid, and 1 quart water. 



POLYPUS OF THE VAGINA OR UTERUS. 



A polypus is a tumor growing from the mucous membrane, and 

 often connected to it by a narrow neck. A definite cause can not 

 always be assigned. If growing in the vagina, a polypus may project 

 as a reddish, rounded tumor from the vulva, especially during the 

 act of passing water. It can be distinguished from descent of the 

 womb by the absence of the orifice of that cavity, which can be felt 

 by the oiled hand beyond the tumor in the depth of the vagina. From 

 a vaginal hernia caused by the protrusion of some abdominal organ 

 enveloped by the relaxed wall of the vagina it may be distinguished 

 by its persistence, its firm substance, and the impossibility of return- 

 ing it into the abdomen by pressure. A hernia containing a portion
