n
the ox it will be necessary to push it out by manipulation through the
sheath. In difficult cases the narrow opening of the sheath may be slit
open.

WOUNDS OF 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 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 strychnin, 1 grain twice 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 returning it into the abdomen by pressure. A hernia containing a portion
of bowel gurgles when handled and can be completely effaced by pressure,
