nes become of a rosy or
deep-red color at the outset; if the fever is attended with distinct
alteration of the blood, as in influenza, and at the end of two or three
days in severe cases of pneumonia or other extensive inflammatory
troubles the mucous membranes are tinged with yellow, which may even
become a deep ocher in color, the result of the decomposition of the
blood corpuscles and the freeing of their coloring matter, which acts as
a stain. At the outset of a fever the various glands are checked in
their secretions, the salivary glands fail to secrete the saliva, and we
find the surface of the tongue and inside of the cheeks dry and covered
with a brownish, bad-smelling deposit. The excretion from the liver and
intestinal glands is diminished and produces an inactivity of the
digestive organs which causes a constipation. If this is not remedied at
an early period, the undigested material acts as an irritant, and later
we may have it followed by an inflammatory process, producing a severe
diarrhea.

The excretion from the kidneys is sometimes at first entirely
suppressed. It is always considerably diminished, and what urine is
passed is dark in color, undergoes ammoniacal change rapidly, and
deposits quantities of salts. At a later period the diminished excretion
may be replaced by an excessive excretion, which aids in carrying off
waste products and usually indicates an amelioration of the fever.

While the ears, cannons, and hoofs of a horse suffering from fever are
usually found hot, they may frequently alternate from hot to cold, or be
much cooler than they normally are. This latter condition usually
indicates great weakness on the part of the circulatory system.

It is of the greatest importance, as an aid in diagnosing the gravity of
an attack of fever and as an indication in the selection of its mode of
treatment, to recognize the exact cause of a febrile condition in the
horse. In certain cases, in very nervous animals, in which fever is the
result of nerve influence, a simple anodyne, or even only quiet with
continued care and nursing, will sometimes be sufficient to diminish it.
When fever is the result of local injury, the cure of the cause produces
a cessation in the constitutional symptoms. When it is the result of a
pneumonia or other severe parenchymatous inflammation, it usually lasts
for a definite time, and subsides with the first improvement of the
local trouble, but in these cases we constant
