s a
diagnostic point between meningitis and rabies and which renders the
animal with the former disease less dangerous to handle. If fastened by
a rope to a stake or post, the animal will wander in a circle at the end
of the rope. It wanders almost invariably in one direction. The pupils
may be dilated or contracted, or we may find one condition in one eye
and the opposite in the other.

The period of excitement is followed by one of profound coma, in which
the animal is immobile, the head hanging and placed against the corner
of the stall, the body limp, and the motion, if demanded of the animal,
unsteady. Little or no attention is paid to the surrounding noises, the
crack of a whip, or even a blow on the surface of the body. The
respiration becomes slower, the pulsations are diminished, the coma
lasts for variable time, to be followed by excesses of violence, after
which the two alternate, but if severe the period of coma becomes longer
and longer until the animal dies of spasms of the lungs or of heart
failure. It may die from injuries which occur in the ungovernable
attacks of violence.

_Complication of the feet._--The feet are the organs which are next in
frequency predisposed to congestion. This congestion takes place in the
laminae (podophyllous structures) of the feet. The stupefied animal is
roused from its condition by excessive pain in the feet and assumes the
position of a foundered horse; that is, if the fore feet alone are
affected, they are carried forward until they rest on the heels; and if
the hind feet are affected, all the feet are carried forward, resting on
their heels, the hind ones as near the center of gravity as possible. In
some cases the stupor of the animal is so great that the pain is not
felt, and little or no change of the position of the animal is
noticeable. The foot is found hot to the touch, and after a given time
the depressed convex sole of typical founder is recognized.

_Pleurisy._--This is a rare complication, but when it does occur it is
ushered in by the usual symptoms of depression, rapid pulse, small
respiration, elevation of the temperature, subcutaneous edema of the
legs and under surface of the belly, and we find a line of dullness on
either side of the chest and an abscess of respiratory murmur at the
lower part. If it is severe, there may be an effusion filling one-fourth
to one-third of the thoracic cavity in from 36 to 48 hours.

_Pericarditis_ is an occasional co
