a sharp knife and the application of a cooling lotion, such as is
recommended for conjunctivitis, will soon reduce the swelling and restore
it to its normal function.

There is, however, a tendency for an inflammation of this membrane to take
on a chronic character, which may eventually result in a permanent
enlargement, resembling a tumor. When it attains sufficient size to
protrude itself permanently over the eye, or project between the lids so as
to obstruct the sight, its removal may become necessary. A threaded needle
is passed through the body of the enlarged mass, by which the membrane is
drawn out as far as possible, then with a blunt pair of scissors it may be
dissected away from its attachments. The eye is afterwards treated with
simple cooling lotions.

DISEASES OF THE EAR.

By M. R. TRUMBOWER, D. V. S.

[Revised by Leonard Pearson, B. S., V. M. D.]

Diseases of the ears of cattle are not very common, for the reasons
probably that they are not subjected to the brutality of drivers so much as
horses and that the horns to a great extent protect them against external
violence.

OTITIS (INFLAMMATION OF THE INTERNAL EAR).

Inflammation of the deep part of the ear is often difficult to recognize in
cattle. It may be caused by disease of bone in that region, from blows
inflicted by drivers, or from injury by other cattle. Occasionally the ear
becomes involved in actinomycosis (lumpy jaw), or the inflammation may be
the result of a tuberculous affection.

_Symptoms._--The animal will hold its head to one side, or shake it, while
the ear itself is held immovable. The movement of the jaws in eating
usually gives rise to a manifestation of pain; the base of the ear may be
feverish and swollen, and very sensitive to the touch. If the inflammation
has advanced to a suppurative stage, offensive matter will flow from the
ear.

_Treatment._--At first, hot fomentations to reduce pain and fever, followed
by a sharp blister below the ear. Laudanum, 1 part to 10 of sweet oil, may
be injected into the ear to relieve pain and to soften the secretions. If
there is a discharge from the ear, it should be thoroughly washed out by
injecting warm soapsuds until all the matter has been washed away; then
inject the following mixture twice a day: Sulphate of morphia, 20 grains;
water, 1 pint; glycerin, 4 ounces.

ABSCESS.

Abscesses, caused by contusions, sometimes form about the base of the ear,
either inside or
