scharge usually signifies disease of the
sinuses. The glands under and between the bones of the lower jaw may be
enlarged. The peculiar ragged-edged ulcer of glanders is not to be found
on the membrane within the nostrils, but occasionally sores are to be
seen there. If there is any doubt about it, the symptoms of glanders
should be well studied in order that one may be competent to form a safe
opinion.

The eye on the side of the discharging nostril may have a peculiar
appearance and look smaller than its fellow. There may be an
enlargement, having the appearance of a bulging out of the bone over the
part affected, between or below the eyes. The breath may be offensive,
which indicates decomposition of the matter or bones or disease of the
teeth. A diseased tooth is further indicated by the horse holding his
head to one side when eating, or by dropping the feed from the mouth
after partly chewing it. When the bones between the eyes, below the
eyes, and above the back teeth of the upper jaw are tapped on, a hollow,
drumlike sound is emitted, but if the sinus is filled with pus or
contains a large tumor the sound emitted will be the same as if a solid
substance were struck; by this means the sinus affected may be located
in some instances. The hair may be rough over the affected part, or even
the bone may be soft to the touch and the part give somewhat to pressure
or leave an impression where it is pressed upon with the finger.

_Treatment._--The cause of the trouble must be ascertained before
treatment is commenced. In the many cases in which the animal is in poor
condition (in fact, in all cases) he should have the most nutritive feed
and regular exercise. The feed, or box containing it, should be placed
on the ground, as the dependent position of the head favors the
discharge.

The cases that do not require a surgical operation must, as a rule, have
persistent medical treatment. Mineral tonics and local medication are of
the most value. For eight days give the following mixture: Reduced iron,
3 ounces; powdered nux vomica, 1 ounce. Mix and make into 16 powders;
one powder should be mixed with the feed twice a day. Arsenious acid
(white arsenic) in doses of from 3 to 6 grains three times daily is a
good tonic for such cases. Sulphur burnt in the stable while the animal
is there to inhale its fumes is also a valuable adjunct. Care should be
taken that the fumes of the burning sulphur are sufficiently diluted
with air
