ON VERTIGO AND PARALYSIS.

my practice to a yearling (off) filly. Nothing new, perhaps, will 
be recognized in the train of symptoms, which very much resem¬ 
bled the commencement of palsy of the hind quarters in a very 
mild form. She knuckled in her hind pasterns, and there was a 
crackling noise heard in the joints. To this succeeded a slight 
degree of immobility, and Avant of steadiness in walking. After 
the lapse of three or four days, the off-fore-leg became involved, 
and the appetite began to be slightly impaired. 
On first seeing my patient, I recognized by her gait some para¬ 
lytic affection. I marked the unsteady movements—the partial 
withdrawal of nervous power from the hind quarters—-the peculiar 
dragging movements of the hind and off fore legs—the comatose 
state into which the animal sunk after exertion, and the unnatural 
position in which she would then often stand—the unusual dilata¬ 
tion of the pupils—I he general shining, glassy appearance of the 
eyes, and the evident partial blindness; all these confirmed the 
correctness of my opinion. 
Treatment. September 23tZ, 1839.—I abstracted blood to the 
amount of six quarts from the right jugular vein—inserted a seton 
on each side of the poll—applied the turpentine liniment over the 
dorsal and lumbar regions—and proceeded to give an aloetic purge 
in combination with one drachm of calomel. This having done its 
duty, I commenced with the medicine on which I placed my great¬ 
est confidence, the powdered nux vomica in combination with the 
hydriodate of potassa and calomel, according to the following 
formula:— 
R. Pulv. nucis vomicao. jj 
Hydriod. potassae . gr. x 
Hydr. chlor. 9j 
Camphorae . jj 
Pulv. gent. jij 
Make into a ball to be given daily. 
28//i.— No marked alteration ; appetite tolerably good, faeces in 
their natural state.

October 3(/.—The amendnient very great; the gait steady; 
countenance more animated, and less degree of somnolency : appe¬ 
tite inquoved, and excretions natural.
