with the eyeball, the disease will eventually cause emaciation and death of
the animal. The enucleation of the eyeball should not be undertaken by
anyone unacquainted with the anatomical structures involved in such an
operation. When the operation is performed early enough the result is
generally satisfactory.

Bony tumors of the orbit, the result of bruises, fractures, etc., are
occasionally present in cattle. They may encroach upon the contents of the
orbit, causing paralysis of the optic nerve--the condition known as
amaurosis--or by pressure upon the posterior surface of the eyeball force
it forward, or produce atrophy (shrinking). They may displace the eye in
any direction, with or without disturbing vision.

Fibrous tumors growing within the orbit will produce symptoms similar to
those of bony tumors.

_Treatment._--When the outlines of the tumor, whether fungoid, bony, or
fibrous, can be detected, an operation for its removal should be undertaken
as soon as the sight of the eye is in any manner disturbed.

DISLOCATION OF THE EYEBALL.

The eyeball may be torn out of its socket by the horns of another animal,
or it may be crowded out with the blunt end of a club, cane, or probe in
the hands of a brutal attendant.

_Treatment._--When the optic nerve is not lacerated and the retractor
muscles at the back of the eye are intact, an attempt at reduction is
advisable. This, however, must follow very soon after the injury--before
swelling takes place. Divide the outer corner of the eyelid to enlarge the
orifice, then by pressure with the fingers of both hands placed upon the
sides of the eye the ball may be put into its place. Apply a firm compress
over the injured eye and keep it constantly wet with cold water containing
1 dram of sugar of lead to each quart.

If the attempt at reduction proves unsuccessful the artery at the back of
the eye should be ligated, and then the whole mass cut off as deep within
the orbit as possible. The orbital cavity, after washing it out with a 3
per cent solution of carbolic acid or compound cresol, should be packed
daily with fresh absorbent cotton.

INFLAMMATION AND ENLARGEMENT OF THE HAW.

The haw, or membrana nictitans, is subject to inflammation and swelling
from the extension of conjunctivitis, or direct injury by foreign
substances. It presents a red, swollen appearance, accompanied with
considerable pain and a profuse flow of tears. A slight scarification with
