IN VERTIGO.

No great change took place until the evening of the 25th, 
when a most violent relapse occurred : he pushed with all his 
might against the wall ; he threw himself down, and still con¬ 
tinued to force himself against the wall. Getting up again after 
some hours, he forced his head to the bottom of the manger. A 
cold sweat covered his shoulders; his respiration was loud ; his 
head was hot, particularly about the forehead, and he continu¬ 
ally and forcibly ground his teeth. 
26tA. —Profound drowsiness. At eleven o’clock a copious dis¬ 
charge of red-coloured and strong smelling urine. The bottom 
of the eye reflected a bright opaline colour. 
27tA. —He died at eleven o’clock, after struggling violently. 
A little while before he had attempted to eat and to drink, but 
was unable to swallow. 
CASE VI. 
Is? Julyy 1822.—A mare was attacked. She was immediately 
bled, and sedative drinks were administered, but without any 
good effect. On the third day of the disease, at the recommen¬ 
dation of M. Dupuy, who was then professor at Alfort, twenty 
grains of emetic tartar, dissolved in about a pint of warm water, 
were injected into the jugular. Almost immediate relief fol¬ 
lowed. The horse got better and better during the space of 
a month, and was considered to be out of danger : a sudden 
relapse then occurred; the animal became immobile, and died of 
marasmus. 
It has hitherto been seen that bleeding is, at least, ineffica¬ 
cious if it is not injurious in vertigo, counterbalancing the good 
efifects of the emetic, and the emetic, perhaps, given in too 
small a quantity. The following facts will clearly shew that 
bleeding has an injurious effect. 
CASE VII. 
10th May, 1825.—A horse, belonging to the Comte de P—, 
two months before had an attack of staggers that was at that 
time an epizootic complaint. He now lay on his litter in an ap¬ 
parently desperate state, and the illness of his former attendant 
had prevented any thing being done. I administered an ounce 
of emetic tartar in a drink. The horse remained for two days 
without power to rise; he had extraordinarily loud horborigmi, 
and his head was paralyzed and motionless on the litter. At the 
end of that time the owner sent for the knacker to destroy and 
take him away; previously, however, a last attempt was made to 
get him on his legs, which succeeded. 1 Ic no sooner got a little 
firm in his new position than he staled abundantly, drank half a
