orate of potassium diluted with a pint of water three times a day as
a drench. Be careful when giving the drench; do not pound the horse on
the gullet to make him swallow; be patient, and take time, and do it
right.

If the weather is cold, blanket the animal and keep him in a comfortable
stall. If the throat is sore, treat as advised for that ailment, to be
described hereafter.

If, after 10 days or 2 weeks, the discharge from the nostrils continues,
give one-half dram of reduced iron three times a day. This may be mixed
with damp feed. Common cold should be thoroughly understood and
intelligently treated in order to prevent more dangerous diseases.

CHRONIC CATARRH (OR NASAL GLEET, OR COLLECTION IN THE SINUSES).

This is a subacute or chronic inflammation of some part of the membrane
affected in common cold, the disease just described. It is manifested by
a persistent discharge of a thick white or yellowish-white matter from
one or both nostrils. The commonest cause is a neglected or badly
treated cold, and it usually follows those cases where the horse has
suffered exposure, been overworked, or has not received proper feed,
and, as a consequence, has become debilitated. It may occur as a sequel
to influenza.

Other but less frequent causes for this affection are: Fractures of the
bones that involve the membrane of the sinuses, and even blows on the
head over the sinuses. Diseased teeth often involve a sinus and cause a
fetid discharge from the nostril. Violent coughing is said to have
forced particles of feed into the sinus, which acted as a cause of the
disease. Tumors growing in the sinuses are known to have caused it. It
is also attributed to disease of the turbinated bones. Absorption of the
bones forming the walls of the sinuses has been caused by the pressure
of pus collecting in them and by tumors filling up the cavity.

_Symptoms._--Great caution must be exercised when examining these cases,
for the horse may have glanders, while, on the other hand, horses have
been condemned as glandered when really there was nothing ailing them
but nasal gleet. This is not contagious, but may stubbornly resist
treatment and last for a long time. In most cases the discharge is from
one nostril only, which may signify that the sinuses on that side of the
head are affected. The discharge may be intermittent; that is,
quantities may be discharged at times and again little or none for a day
or so. Such an intermittent di
