ST. VITUS ? S DANCE IN THE HORSE.

Were given without success, although at eight o’clock the pulse 
was a little more developed, and the temperature of the body 
not quite so low. The patient fell on her litter at nine o’clock, 
and the two syriiptoms just referred to, and which had some¬ 
what diminished, acquired the highest possible intensity. The 
pain seemed to increase; the limbs became stiffened; and death 
took place at half past nine. All the subcutaneous vessels were 
gorged with very black blood; the lungs were thickened and 
also gorged w T ith blood, shewing a great number of their small 
vessels ruptured ; the trachea was filled with a frothy mucus, in 
which was observed several bloody streaks. The w r all of the left 
ventricle of the heart had one-third more than its natural thick¬ 
ness, and contained no blood. The left auricle, likewise, con¬ 
tained no blood, while the two right cavities, the large veins, 
the liver, and the spleen, w^ere filled wfith blood. M. Liegard 
thought that the mare died of a pulmonary congestion, resulting 
from the obstacle which the hypertrophy opposed to the course 
of the blood.

St. Vitus’s Dance (Chorea) in the Horse. 
By M. De Beaux. 
St. Vitus’s Dance, which is a frequent sequela of distemper 
in dogs, is very rare among the solipede. Gohier and M. Hu- 
zard, senior, have related two cases. M. de Beaux here gives 
a third example, which seemed to him to possess considerable 
interest. The causes of the disease w r ere unknow n to him. The 
animal was destroyed; but examination after death could not 
take place. The following are the symptoms and the treat¬ 
ment:—From the beginning of October 1824, the horse, which 
was glandered, had a violent diarrhoea. The flux from the nose, 
and the enlargement of the lymphatic glands under the jaw r , had 
suddenly disappeared; the faeces were yellow, black, gela¬ 
tinous, and foetid; the pulse small, irregular, and accelerat¬ 
ed ; the mucous membrane yellow r ; partial but abundant 
sweats; the flanks tucked up, without heaving; convulsive 
movements of the limbs at intervals of two hours, after which 
the pulse rose and gave nearly seventy pulsations; the pupils 
were much dilated, and occasionally, for a short period, the 
animal would remain perfectly still; the head elevated, the 
neck stiff, and not conscious of any thing that was passing 
around him. Suddenly a general trembling would come over 
him, followed by profuse sw eats, and then only the pain seemed
