WOUNDS OF THE PENIS. 



X 



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, audit 

 may be to the impossibility of protruding it. 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 hanging 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 stimulants, 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 with leucorrhoea. 

 They 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 red- 

 dish, 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 A T aginal 

 hernia caused by the protrusion of some abdominal organ enveloped 

 by the relaxed wall of the vagina it may be distinguished by its per- 

 sistence, its firm substance and the impossibility of returning it into 

 the abdomen by pressure. A hernia containing a portion of bowel gur- 

 gles when handled and can be completely effaced by pressure, the gut" 

 passing back into the abdomen. 



A polypus iii the womb is less easily recognized. At the time of 

 calving it may be felt through the open mouth of the womb and recog- 

 nized by the educated touch (it must be carefully distinguished from 

 the mushroom-formed cotyledons (Plate xni, Fig. 2), to which in rumi- 

 nants the fetal membranes are attached). At other times, unless the 

 womb is opened in the effort to expel it, the polypus can only be detected
