AND ITS MEMBRANES IN THE HORSE. 523 
logous case in the same Journal. The horse presented the same 
symptoms and the same lesions, with a sensible alteration of the 
muscles. 
M. Chariot has published three cases of palsy in the horse. 
Two of the animals were completely healed by the alternate em¬ 
ployment of antiphlogistics and the nux vomica. In the one that 
died, the spinal marrow was softened from the middle of the neck 
to the first dorsal vertebra. The left brachial plexus was very 
red, and the nerves which proceeded from it. 
A mare, afflicted with complete palsy of the hind limbs, was 
unsuccessfully treated by M. Prevost with the nux vomica in 
large doses. No remarkable alteration was perceived in the dis¬ 
section of her, and during the whole course of the disease she 
had retained the usual feeling in the limbs deprived of all 
motion. 
A softening of the inferior part of the spinal marrow, and a 
sensible alteration in the nerves which proceeded from it, were 
observed by M. Gelle in opening a horse that had died of trau¬ 
matic tetanus. In several dissections that I have made of horses 
that have died of tetanus, I have never failed to find these 
lesions. 
M. Olivier has recorded a case of a palsied mule, in which 
feeling survived the total loss of motion. He found a softening 
of the inferior part of the lumbar portion of the spinal marrow: 
the grey portion of the substance of the cord was reddened, but 
the membranes presented no remarkable alteration. The muscles 
around were infiltered with a yellow fluid, and were easily torn. 
M. Chouard has related two cases of secondary palsy in horses, 
with aneurism of the posterior aorta. In the first, the lumbar 
portion of the spinal marrow was in an almost fluid state. In the 
second, it had an unnatural hardness. In both, the membranes 
were injected. These different states of the spinal marrow have 
been considered by some authors as indicating different degrees 
of inflammation. 
A fact related by MM. Kerseau and Lacoste, deserves parti¬ 
cular attention. A cow had calved without difficulty, and with 
no appearance of disease. In the course of the night she fell, 
and was unable to rise. The cow was able to move her hind 
limbs, and that with considerable violence, but they had lost all 
feeling. The remedial means which were used not producing 
any effect, the animal was destroyed. The lumbar portion of the 
spinal cord was very red on its superior part, and the fasciculi 
which proceeded from it were injected for the space of two 
inches. The lower fasciculi presented no other alteration than a
