e case of such as have no free exercise
in the fields, and are subject to constant association with a vigorous
young bull. A more frequent cause is the excitation or congestion of some
part of the genital organs. Disease of the ovaries is preeminently the
cause, and this may be by the formation of cysts (sacs containing liquid)
or of solid tumors or degenerations, or, more commonly than all, the
formation of tubercle. Indeed, in case of tuberculosis attacking the
abdominal organs of cows, the ovaries or the serous membranes that support
and cover them (the broad ligaments of the womb) are peculiarly subject to
attack, and the animal has constant sexual excitement, incessantly riding
or being ridden by other cattle, having no leisure to eat or chew the cud,
but moving restlessly, wearing the flesh off its bones, and gradually
wasting. In some localities these cows are known as "bullers," because they
are nearly always disposed to take the bull, but they do not conceive, or,
if they do, they are subject to early abortions. They are, therefore,
useless alike for the dairy and for the feeder, unless the removal of the
ovaries subdues the sexual excitement, when, in the absence of tuberculous
disease elsewhere, they may be fattened for the butcher.

Among the other sources of irritation charged with causing nymphomania are
tumors and cancers of the womb, rigid closure of the neck of the womb so
that conception can not occur and the frequent services by the male which
stimulate the unsatisfied appetite, inflammation, and a purulent discharge
from the womb or vagina.

_Treatment._--The treatment in each case will vary with the cause and is
most satisfactory when that cause is a removable one. Overfeeding on richly
nitrogenous feed can be stopped, exercise in the open field given, diseased
ovaries may be removed (see "Castration," p. 299), catarrhs of the womb and
passages overcome by antiseptic, astringent injections (see "Leucorrhea,"
p. 224), and tumors of the womb may often be detached and extracted, the
mouth of that organ having been first dilated by sponge tents or otherwise.
The rubber dilator (impregnator), sometimes helpful in the mare, is rarely
available for the cow, owing to the different condition of the mouth of the
womb.
