284 CASES OF PALSY IN THE HORSE. 
under the serous membrane that lines the left ventricle of the 
heart. 
There was no sensible alteration of the brain or its membranes, 
or the spinal marrow, but there was a great injection of the 
arachnoid membrane of the lumbar portion of the membrane, and 
whose intense red colour offered a singular contrast with the pale 
tint of the other portion of the membrane. There was no 
change in the arachnoid fluid, nor in the pia-mater, and the word 
injection is designedly employed in distinction from inflam¬ 
mation. 
CASE II. 
An Hungarian draught horse, nine years old, and of middle 
size, belonging to a waggoner, was put to work after four days’ 
rest, and having been full-fed, when, all at once, he began to per¬ 
spire abundantly, and was lame in the right hind leg. The 
lameness increased, and extended to both legs ; and, eight or ten 
minutes after the first appearance of these symptoms, he fell 
totally paralyzed in both hind legs. A message having been 
sent to the school, two pupils were immediately dispatched to 
the place where he lay, who, seeing the alarming state in which 
he appeared to be, advised that he should be brought immedi¬ 
ately to the hospital. He was conveyed thither on a sledge, at 
six o’clock in the evening; but before he was moved the pupils 
bled him freely, by opening the two saphenas, and cutting off 
the end of the tail. 
Having arrived at the school, he at once began to eat, but 
presented all the symptoms of complete palsy. Ten pounds of 
blood were abstracted ; stimulating frictions were applied to the 
loins; he was warmly covered, and acidulated drinks were ad¬ 
ministered. During the night the horse frequently moved his 
hind limbs, and on their being pricked, it was manifest that there 
was a return of sensibility to them. 
15th .—The horse appeared to be better. The sensibility of 
the limbs was greater, and he turned himself upon- his litter. 
Five pounds of blood were taken from the tail, and the other 
treatment continued. 
1 6th .—More power of motion in his limbs, but less sensibility. 
He ate his litter, and eagerly devoured the hay that was put 
before him. Five pounds of blood were taken from the jugular; 
stimulating injections were thrown up, and a laxative drink ad¬ 
ministered. 
17 th .—No amendment. We attempted to raise him, but we 
could not support him on his hind extremities. He was aban¬ 
doned by the proprietor. Continue the same treatment.
