membranes. For this purpose a saturated
solution of boric acid or listerine 1 part to 10 of water may be used. When
the fever runs high, Glauber's salt (sulphate of soda) may be given in
4-ounce doses once a day. The animal should be kept in a darkened stable,
on soft or green feed.

FRACTURE OF THE ORBIT.

This accident occasionally occurs among belligerent animals, or as the
result of blows delivered by brutal attendants. The orbital process above
the eye may be entirely crushed in, pressing down upon the eyeball. In such
an event the depressed bone should be elevated into its proper place, and
if it fails to unite it may have to be removed with saw or chisel. The
margin of the orbit may be crushed at any point and cause periorbital
abscess, or necrosis may result from the presence of a splinter of bone or
the excessive destruction of bone. In all cases of fracture the animal
should be kept by itself until the injured part heals.

NECROSIS OF THE BONY ORBIT.

As the result of fracture of the margin of the orbit a part of the injured
bone may become necrosed (dead), and periostitis and periorbital abscess
will follow as a consequence. The discovery of this disease will at first
resemble abscess, but on making an examination with a probe after the
abscess is open we find the bone rough and brittle at the point of disease.
The discharge has a peculiar fetid odor, and is often mixed with blood.

_Treatment._--The affected bone must be laid bare and all diseased portions
removed by scraping or, if necessary, with saw or chisel, disregarding the
extent of the injury or the size of the wound necessary to be inflicted. A
large portion of the bony orbit may be removed without serious danger to
the eye, provided the eyeball itself has not been previously affected by
the disease or involved in the original injury.

TUMORS OF THE ORBIT.

A fungous tumor of the eyeball or orbit occasionally appears, which is
designated fungus haematodes. This may arise without any appreciable cause,
or as the result of a wound. It frequently commences within the eyeball as
a small, red mass, eventually bursts through, and pushes its way outside
the orbit as a large, dark-red mass, bleeding at the slightest touch. It
has a peculiar, fetid odor, and early in its appearance destroys sight,
involving all the contents of the orbit, not infrequently the bony wall
itself.

Unless the tumor is totally removed in its early stage of growth, to
