PALSY IN THE HORSE. 663 
one ; the other is formed with reference to muscular strength and 
endurance alone. 
Partial Paralysis. —Of these cases we have plenty in all 
our patients, and most untractable ones they are : sometimes they 
are fatal. An old pupil and valued friend of mine, Mr. Chapman,' 
who kindly conducted my business for me when 1 was ill, was sent 
for, in order to examine a horse. The symptoms were, heat of 
mouth, heaving at the flanks, a hard and quick pulse, and the 
exhibition of great pain. As he stood by his side and looked at 
him, he observed some slight spasms of the shoulder, and extend¬ 
ing along the side. He naturally concluded that it was a case of 
pleurisy, and he bled the animal and gave fever medicine. 
On calling a few hours afterwards, he found the horse in still 
greater pain, and his left leg was becoming powerless. The horse 
could not bear upon it, and he shrunk at the slightest touch. 
(There is a strange caprice about this. In many cases there is palsy 
of the sensitive as well as the motor nerves; at other times the 
natural feeling remains, although the power of motion is lost: 
occasionally the sensibility is increased to an almost inconceivable 
degree: but generally both nerves are gradually involved, and 
share in the same loss of power.) 
He soon after this fell, and beat himself dreadfully about. 
My young friend began to understand the case : again he ordered 
the limb to be frequently fomented, he rubbed in a stimulating 
liniment all over it, and he gave a strong dose of physic. On the 
following day he began to give opium and spirit of nitrous ether. 
The horse had been previously set on his legs with a great 
deal of difficulty; he stood continually shifting his position, so 
far as he could do it with his hind feet, and trying in vain to rest 
a little of his weight on the affected limb. At length the power 
of the other leg began to fail, and he again fell down, and, 
unless forcibly held down, beat his head about, and fought and 
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 tlie central canal 
was black. The superior and lateral columns presented no 
lesion. 
1 scarcely know a plainer and more interesting case of inflam¬ 
mation of tlie spinal chord and its membranes, and the paralytic 
aflection consccjuent on this. It is only deficient in one particular.
