substance from which they were derived. The ganglion, re¬ 
sulting from the union of the two roots, was not altered. The 
arachnoid membrane was red at that place, with denser minute 
points of blood; the rest of the spinal marrow was in its natural 
state. 
CASE X. 
Selected from the Clinical Records of the School of Alfort , and communi¬ 
cated by Professor Moiroud. 
The horse which was the subject of this case was attached to 
an empty cart, which he drew on the 21st of January 1830, 
through the village of Maison Alfort, when the driver thought 
that he bent one of his hind limbs in a curious way, and seemed 
to fear to put it to the ground. Having immediately detached 
the animal from the vehicle, some persons endeavoured to re¬ 
conduct him to the house of his master, who lived at a short 
distance from the place; but he had scarcely gone two or three 
steps, before his legs bent under him, and he fell. All attempts 
to raise him were fruitless : he was placed on a kind of carriage, 
and brought immediately to Alfort. 
On its arrival, M. Moiroud examined it, and perceived that 
feeling was altogether destroyed in the middle and posterior re¬ 
gions of the body: the back was plainly included. Pricks 
made with a pin, and even with a bistoury, caused no pain. The 
right fore limb was less sensible, and less agitated, than the left. 
The posterior members executed some very extensive motions ; 
the pulse was frequent, small, feeble, and almost imperceptible. 
Bleed to six pounds ; use irritating frictions on the croup and 
the hind limbs ; give purgative drinks, and throw up injections 
in which emetic tartar has been dissolved. Towards eleven 
o’clock at night the animal seemed to be a little more tranquil, 
the hind limbs were stiff, and less agitated. 
On the following day the animal was better; sensibility seem¬ 
ed to be returning to the hind limbs ; the pulse was more deve¬ 
loped. The patient often lifted his head, and stretched it back 
over his shoulders ; he made frequent efforts to rise, and with the 
assistance of some of the pupils, he was placed on his legs ; but 
his hind limbs gave way afresh, and he soon fell again upon his 
litter. Bleed again to six or seven pounds ; give white water 
with honey : apply synapisms to the thighs; and the same fric¬ 
tions as yesterday.

behind, and the motion of the posterior extremities was almost 
entirely lost; but the action of the head and neck were more 
violent than ever. He lifted his muzzle in the air, ground his
