ly have exacerbations of
fever due to secondary inflammatory processes, such as the formation of
small abscesses, the development of secondary bronchitis, or the death
of a limited quantity of tissue (gangrene).

In specific cases, such as influenza, strangles, and septicemia, there
is a definite poison in the blood-vessel system and carried to the heart
and to the nervous system, which produces a peculiar irritation, usually
lasting for a specific period, during which the temperature can be but
slightly diminished by any remedy.

In cases attended with complications, the diagnosis at times becomes
still more difficult, as at the end of a case of influenza which becomes
complicated with pneumonia. The high temperature of the simple
inflammatory disease may be grafted on that of the specific trouble, and
the determination of the cause of the fever, as between the two, is
therefore frequently a difficult matter but an important one, as upon it
depends the mode of treatment.

Any animal suffering from fever, whatever the cause, is much more
susceptible to attacks of local inflammation, which become complications
of the original disease, than are animals in sound health. In fever we
have the tissues and the walls of the blood vessels weakened, we have an
increased current of more or less altered blood flowing through the
vessels and stagnating in the capillaries, which need but an exciting
cause to transform the passive congestion of fever into an active
congestion and acute inflammation. These conditions become still more
distinct when the fever is accompanied with a decided deterioration in
the blood itself, as is seen in influenza, septicemia, and at the
termination of severe pneumonias.

Fever, with its symptoms of increased temperature, acceleration of the
pulse, acceleration of respiration, dry skin, diminished secretions,
etc., must be considered as an indication of organic disturbance. This
organic disturbance may be the result of local inflammation or other
irritants acting through the nerves on nerve centers, alterations of the
blood, in which a poison is carried to the nerve centers, or direct
irritants to the nerve centers themselves, as in cases of heat stroke,
injury to the brain, etc.

The treatment of fever depends upon its cause. One of the important
factors in treatment is absolute quiet. This may be obtained by placing
a sick horse in a box stall, away from other animals and extraneous
noises and sh
