ANIMAL PATHOLOGY. 
Loss of Motion , Sensation remaining perfect. — M. Bouley, an 
intelligent veterinary practitioner in Paris, and first among his 
brethren in the pursuit of science, says, that he had under his 
care an entire draught horse, with total want of power of motion 
of the hind legs, but the feeling remaining perfect. These 
symptoms continued three days, and then the animal died. “All 
the inferior part of the spinal marrow was softened and semi- 
fluid, while the superior ’part had undergone no change*.” The 
inferior motor columns were diseased, decomposed, and then 
their function ceased; the superior sensitive columns exhibited no 
morbid lesion, and perfectly discharged their duty. 
Loss of Feeling , the Power of Motion being retained. — On 
the other hand, M. Bouley quotes a case from M. Kerseau, of 
a cow that fell the day after calving ; she was able to move her 
hind limbs, and that with considerable violence ; but they had 
lost all feeling. Remedial measures appearing to have no effect, 
she was destroyed. “The lumbar portion of the spinal cord 
was very red on its superior part, and the fasciculi were injected 
for the space of two inches. The lower fasciculi presented no 
other alteration than a yellow tint, which was perceived through 
the whole course of the spinal marrow.” Can any thing be 
more decisive ? 
Loss of Feeling and Motion. — Take another case, recorded 
by the same accurate observer. The hind limbs of a seven-year 
old horse were entirely deprived of feeling, and the power of 
motion. The animal lingered five days; he seemed to suffer 
little, and he was anxious to eat — (another illustration of the 
nervous system, gentlemen, and shewing you the independent 
function of the organic nerves) — he lingered five days, and he 
died : feeling and motion had disappeared, and what do we find ? 
“The spinal marrow, the whole of it, was softened and semi-fluid 
from the 10th dorsal vertebra to the lumbar enlargement, and 
including it.” 
Take an example from Professor Renault. A horse injured 
in casting was kept during a month ; the power of motion in 
the hind extremities was gone from the beginning, and that of 
feeling gradually, and at length perfectly disappeared ; but the 
horse continued in good spirits, and feeding well. He was at 
length destroyed. “ The spinal marrow at the bending of the 
neck was softened and changed to a pultaceous and red matter 
for about two inches in extent.” 
If I had fabricated these cases — and I have purposely intro- 
duced no case of my own — could they have been more conclusive ?
