useful in relieving the inflammation. Easily digested feeds, and in case
the animal has difficulty in swallowing, soft feeds and gruels, should be
given. The throat may be kept covered with a layer of antiphlogistin and
bandaged. Glycoheroin may be given in from teaspoonful to tablespoonful
doses, depending on the size of the animal. Chlorate of potassium may be
given in the drinking water.

If the animal becomes run down in flesh, as sometimes occurs in chronic
catarrh, bitter tonics should be given. In the latter disease, it is
sometimes necessary to trephine and wash out the sinus or sinuses affected
with an antiseptic solution. It may be necessary to continue this treatment
for several weeks.

BRONCHITIS.--Inflammation of the bronchial tubes may be either acute or
chronic. Acute bronchitis is especially common in the horse, while the
chronic form is more often met with in the smaller animals, especially
hogs. This disease is most common among horses during the changeable
seasons of the years. It is _caused_ by warm, close stables or stalls, and
irritating gases emanating from the floor, or manure in the stall. In
general, the causes are about the same as in cold in the head. In young
animals and hogs, the inhalation of dust, and bronchial and lung worms
commonly cause it. Verminous bronchitis usually becomes chronic.

_In the acute form_ of the disease the _symptoms_ come on very quickly, the
fever is high and the pulse beats and respirations are rapid. Chilling of
the body occurs, and the animal may appear dull and refuse to eat. The
animal coughs frequently. Recovery occurs within a few days, unless
complicated by sore throat and pneumonia. In the horse, bronchitis is not a
serious disease, but in other animals recovery is delayed and complications
are more common.
