aracter of the spasm-locked jaw, retraction of the eyeballs, the
difficulty in swallowing due to spasms of the muscles of the pharynx,
and above all, the absence of paralysis, should serve to make the
distinction.

_Prevention._--When a valuable horse has sustained a wound that it is
feared may be followed by tetanus, it is well to administer a dose of
tetanus antitoxin. This is injected beneath the skin with a hypodermic
syringe. A very high degree of protection may in this way be afforded.
This antitoxin should be administered only by a competent veterinarian.

_Treatment._--The animal should be placed in a box stall without
bedding, as far as possible from other horses. If in a country district,
the animal should be put into an outbuilding or shed, where the noise of
other animals will not reach it; if the place is moderately dark, it is
all the better; in fly time it should be covered with a light sheet. The
attendant must be very careful and quiet to prevent all unnecessary
excitement and increase of spasm. Tetanus antitoxin appears to be useful
as a remedy in some cases, if given in very large quantities early in
the disease; otherwise it is useless. Subcutaneous injections of
carbolic acid in glycerin and water (carbolic acid 30 grains, glycerin
and water each 1 ounce) appear to be useful in some cases. Injections
should be given twice daily.

A cathartic, composed of Barbados aloes 6 to 8 drams, with which may be
mixed 2 drams of the solid extract of belladonna, should be given at
once. This is best given in a ball form; if, however, the animal is
greatly excited by the attempt or can not swallow, the ball may be
dissolved in 2 ounces of olive oil and thrown on the back of the tongue
with a syringe. If the jaws are set, or nearly so, an attempt to
administer medicine by the mouth should not be made. In such cases
one-quarter of a grain of atropia, with 5 grains of sulphate of morphia,
should be dissolved in 1 dram of pure water and injected under the skin.
This should be repeated sufficiently often to keep the animal
continually under its effect. This will usually mitigate the severity of
the spasmodic contraction of the affected muscles and lessen sensibility
to pain. Good results may be obtained sometimes by the rectal injection
of the fluid extract of belladonna and of cannabis indica, of each 1
dram, every four or six hours. This may be diluted with a quart of milk.
