s threatened. Such
serum, however, should be used in sufficiently large doses, as repeated
experience has proved that small doses have no beneficial action on the
disease.

More recently salvarsan is being highly recommended for the treatment of
the pneumonic form of influenza, and by many investigators it is
considered as a specific for this affection. A single injection of this
preparation is supposed to result in a rapid clearing of the lungs and
the recovery of the animal is hastened. The cost of this product,
however, at the present time, is exorbitant, and it should be considered
only in the treatment of very valuable animals.

The same procedure as given for influenza should be carried out in the
prevention of this affection.

The diet demands the strictest attention from the outset. In many of the
fevers the feed has to be diminished in quantity and regulated in the
quality of its heat-producing components during the acute part of the
disease, so as to lessen the material for combustion in the inflamed
organs. In edematous pneumonia, on the contrary, all the feed that can
possibly be digested and assimilated must be given. Choice must be made
of the richest material which can be handled by the weakened stomach and
intestines without fatiguing them. Good, sound hay should be chopped
short and dampened or partly boiled; in the latter case the hay tea can
be reserved to use as a drink. Oats may be preferred dry or in other
cases are taken better scalded; in most cases, however, it is better to
give slops of oatmeal, to which may be added a little bran, barley
flour, or boiled milk and wheat flour. Pure cow's milk, not too rich in
fatty matter, may be given alone or with beaten eggs; frequently the
horse has to be coaxed with the milk diluted with several parts of water
at first, but will soon learn to drink the pure milk. Apples and carrots
cut up raw or boiled are useful, and fresh clover in small quantities
will frequently stimulate the appetite. In other words, various feeds
and combinations should be given to the horse. Throughout the course of
the disease and during convalescence the greatest attention must be
taken to cleaning the coat thoroughly so as to keep the glands of the
skin in working order, and light, warm covering must be used to protect
the animal from cold or drafts of air.
