52 THE VETERINARY DOCTOR. 
TREATMENT.—When the premonitory symptoms appear, stop the 
horse, loose the collar, cover the eyes, and wet the head with cold water. 
Drawing a little blood from the mouth often relieves at once. Bromide of 
ammonia or potassa will be found useful as a preventive of further attacks, 
and should be given in doses composed of a half-teaspoonful of the salts. 
in a half-pint of water one to three times a day. Stramonium is of the 
highest value when the symptoms are trembling, convulsions, rolling eyes, 
and sudden fall. Give once in two or three hours, according to the se- 
verity of the case. Aconite will immediately give relief if the disorder re- 
sults from fatigue in hot weather; but should the attack not abate readily, 
it is probably of the nature of apoplexy, with like cause, and the section de- 
voted to that trouble should be consulted. Nux vomica may be given if 
the dung is hard and the urine scanty. It may also be given at night, 
followed in the morning by sulphur, the alternation being kept up as a 
preventive of recurrence of the attack. In this case give ten drops of either. 
The medicines selected should be continued, a dose a day, for at least a 
week after the attack. Avoid undue pressure on the veins by collars, 
bands, and tight reining; shade the top of the head when in the sun, keep- 
ing a sponge wet in cold water between the ears. If the animal is robust, 
give an abundance of moderate work and restrict the feed. After an at- 
tack, turn the animal out for a while, and insure rest and quiet. 
CONCUSSION OF THE BRAIN. 
Concussion of the brain results from a violent blow or other mechan- 
ical agency on the head, and may lead to serious disorders. 
TREATMENT.—Apply arnica lotion freely, and give a dose of five 
drops of diluted arnica three times daily, or oftener if the severity of the 
case demands it. If inflammation ensues, treat as for Brain Fever. 
CEREBRO-SPINAL FEVER. 
The true causes of this disease are unknown, but it is probably due to 
various debilitating conditions, such as over-exertion, indigestible food, foul 
water, or sudden exposure to extreme heat. 
Symptoms.—Many of these are similar to those in man: Sudden 
cramps of the voluntary muscles of the neck and hind limbs, trembling of 
the whole body, and when the attacks come on slowly there is extreme 
dullness and lassitude for many hours, with paralysis of the throat and lips, 
causing a great flow of saliva. General paralysis follows these conditions, 
and eventually the animai is unable to stand, and lies prone upon its side
