SYMPTOMATIC VERTIGO. 
Pus mixed with a certain quantity of healthy blood commu¬

A CASE OF SYMPTOMATIC VERTIGO (STOMACH 
STAGGERS) IN A POST HORSE. 
Bt/ M. Olivier, M.V., d St. Maximin. 
On the 17th of October, 1837, M. Jussieu, a post-master, 
left a horse, six years old, at my infirmary, that had refused his 
food during two days, and had lost all his usual spirit. 
It was about five o’clock in the evening when I saw him. 
He staggered as he walked—fell upon the man who held him— 
and pushed obstinately forward if any one attempted to stop him. 
My prognosis was unfavourable. I inserted two setons on the 
sides of his head, and applied stimulating sinapisms over the 
setons. An ounce of tartarized antimony was administered in an 
infusion of chamomile : laxative injections were also thrown up, 
to one of which I added an ounce of aloes, and a similar quantity 
of sulphate of soda. We were compelled to cast him, in order to 
accomplish this. 
We kept him in this position until one o’clock in the morning, 
when his agitation becoming extreme, and the sweat running from 
him in torrents, we released him, and, placing him in a large stable, 
took every care that he should injure himself as little as possible. 
During the moments of calm he bore heavily on the halters to 
which he was attached, pushing forward—holding his head low, 
and which he inclined constantly to the left side. He was sadly 
outrageous during the greater part of the night. The injections 
which had been thrown up were not returned. The urine was of 
a red colour, and very forcibly expelled. 
From four o’clock in the morning until mid-day, he maintained 
one fixed position, constantly pushing forward. He was uncon¬ 
scious of every thing around him, and was completely blind and 
deaf. 
To this lethargic state succeeded new and still more violent 
struggles. We continued the mucilaginous injections, with the 
addition, twice in the course of the day, of an ounce of emetic 
tartar, with the same quantity of sulphate of soda and nitrate of 
potash. The sinapisms were re-applied on the side of the head.
