PALSY IN THE HORSE.

scrambled with his hind feet. He survived until the fifth day 
after the attack. 
On examining him after death, there was scarcely any thoracic 
or abdominal lesion, but there was spinal disease from the fifth 
to the seventh dorsal vertebra. The membranes of the chord 
were inflamed, the ligamentum denticulatum very much so ; the 
inferior columns were pulpy, and the fluid in the central canal was 
black. The superior and lateral columns presented no lesion. 
I scarcely know a plainer and more interesting case of inflam- 
mation of the spinal chord and its membranes, and the paralytic 
affection consequent on this. It is deficient in one particular only, 
and one which no inquiry could supply, What was the cause of 
the spinal affection ? 
H emiplegi a and Paraplegia. — The human practitioner 
has yet another distinction, hemiplegia and paraplegia. In the 
former the affection is confined to one side of the patient : it 
occupies, as it were, one half of the chord. In paraplegia the 
posterior (lower) extremity on both sides is affected. 
Cases of Hemiplegia . — Few cases of hemiplegia occur in our 
patients. Old Gibson relates some cases of it. If you should 
chance to see his work on farriery on any bookstall, it is worth your 
purchase. There is a great deal of what would yet be considered 
good matter in it. He speaks of it as an epidemic in his time. 
Girard describes what he supposes to be a case of it, but re- 
specting which I have some doubt. It looks to me a great deal 
more like rabies. “ A horse fell while at work. He was raised 
with much difficulty, and was found to be powerless on the left 
side — feeling, however, remained : the left nostril was closed, the 
eye was also closed and ulcerated. Hay was offered to him ; 
he seized it with the right side of his lips ; he opened his mouth 
strangely wide in order to get it to his grinders, but he could not 
masticate it, for all of it presently accumulated between the left 
molars and the cheek. Oats he could not get at all into his 
mouth. In order to drink, he plunged his muzzle in the water 
up to the commissures of his lips, and then sucked up a little 
of the fluid slowly, and with difficulty. He however had evi- 
dently the sense of smell in his left nostril. 
The palsy was not perfect on that side, for he could walk, 
although with a great deal of difficulty. His left legs trembled 
under him as they were dragged after him ; and if he was turned, 
and a little too sharply, towards the left, he fell, but scrambled up 
again with great difficulty. He continued in this state six days, 
and died. The grey substance of the brain was a little more in- 
jected than usual ; and there was a slight injection in the left
