56 ON THE DISEASES OF THE SPINAL CHORD, &C. 
CASE VI. 
In the month of June 1822, complete palsy, cause unknown, 
suddenly attacked an entire sorrel horse, five years old, of good 
constitution, while he was at work. Nothing could arrest the 
rapid progress of the disease; and the animal died forty-eight 
hours after the first attack. 
Examination six hours after death .—This was conducted with 
the assistance of my unfortunate friend, M. Girard, jun. We 
found some traces of inflammation on the abdominal viscera, par¬ 
ticularly on the liver and the stomach ; the lungs were black, 
and the right cavities of the heart very red ; the brain presented 
no lesion; but the spinal marrow, from the middle of the dorsal 
region to the sacrum, had its envelopes injected, and its pulp 
softened and semi-fluid, particularly at the lumbar region. 
CASE VII. 
A grey mare, six years old, was, on the 19th of January 1828, 
suddenly seized with palsy in her hind limbs, immediately after 
she had worked two hours, without seeming to ail any thing. 
The disease ran its course with frightful rapidity, and she died 
fourteen hours after the commencement of the attack. 
Examination twelve hours after death .—The lungs were black, 
and gorged with blood ; the heart enlarged, and discoloured; its 
right cavities very red ; and the brain in its natural state. A red 
fluid had spread itself between the pia mater and the arachnoid 
membrane ; these two membranes were injected from half way 
down the dorsal region to the entrance of the sacrum ; the spinal 
chord was soft and semi-fluid through the whole extent of the 
sacral region. Professor Dupuy assisted me in this examination. 
CASE VIII. 
On the 25th of January 1828, an aged, grey, draught mare 
was brought to me, who had all at once been struck with palsy. 
She died in less than thirty hours. 
At the examination, made in company with my colleague, 
M. Leblanc, I found the same lesions as in the last case; only, 
that the redness of the spinal membranes, and the softening of 
the spinal chord, were more evident. 
It wmdd be easy for me to increase the number of these facts, 
but they all possess a very similar character, and relate to mor¬ 
bid changes of the spinal chord in the dorso-lumbar region; they 
would therefore throw no farther light on the history of these 
maladies. Those which I have described are sufficient to demon¬ 
strate the frequency and the dangerous character of these affec¬ 
tions of the spinal marrow.
