524 ON THE DISEASES OF THE SPINAL CORD, &C. 
yellow tint, which was perceived through the whole course of the 
spinal marrow. 
This case affords a beautiful illustration of the opinion of 
MM. Bell and Majendie respecting the functions of the supe¬ 
rior and inferior portions of the spinal marrow. 
In a stallion affected with complete loss of voluntary motion, 
M. Dupuy found a general softening of the spinal marrow, and 
especially at the dorsal region, where it assumed the form of a 
puriform fluid. 
In the veterinary school at Toulouse a paralytic ox was de¬ 
stroyed during the last year. The spinal marrow was flattened 
and softened at the lumbar region; a false fibrous membrane, 
studded with tubercles and yellow concretions, covered the arach¬ 
noid, and the lumbar and sacral nerves were enveloped by a ge- 
latiform fluid, which was found in the cellular tissue that sepa¬ 
rated every nervous fibril, and with which the neurilema itself was 
impregnated. This false membrane, garnished with tubercles and 
covering the spinal arachnoid, has not been described 
other veterinarian. 
These cases comprise, so far as I am aware, all the knowledge 
we possess on diseases of the spinal marrow in our domestic qua¬ 
drupeds, and on carefully comparing them we may observe— 
1. That in domestic animals the spinal marrow is rarely alter¬ 
ed through the whole of its course. 
2. That the dorsal and lumbar regions are the parts oftenest 
affected. 
3. That inflammation of the spinal marrow of these regions 
always produces palsy, more or less complete, of the abdominal 
members (des membras abdominaux). 
4. That, in some cases, this inflammation is limited to the 
inferior or superior part of the spinal marrow, and that then there 
is loss only of feeling or of motion. 
5. That sometimes animals die of palsy without any organic 
lesion. 
6. Diseases of the spinal marrow are always serious, and often 
mortal. 
Although the greater part of the facts which I have related 
have reference to the horse, they more than suffice to shew how - 
little these diseases of that animal are known. If other proof were 
wanting, I should appeal to the elements of pathology with which 
my friend M. Vatel has enriched veterinary science, and in which 
he has given a very short article on inflammation of the spinal 
marrow, illustrating it by reference to the dog, in which it is 
often the consequence of inflammation of the bowels, but record-
