the first dressing. The foetor was not so considerable — the dis- 
charge less and more healthy. 
I saw him again a few days afterwards, and had much diffi- 
culty in getting near the part affected, not having thrown him. 
After many efforts, however, I succeeded, and drew with a pair 
of forceps out of the sinus a cobweb-like substance near the 
length of the fistula, which was protruding from the orifice. 
1 then injected a solution of chloride of lime, and repeated it a 
few times, and at about the same intervals. The discharge had 
now become healthy pus, and had lost its foetor. The wound 
healed, the horse was sold and put to work, and has been at 
work ever since. 
I saw him a few days ago: there is no discharge from the part, 
nor has there been since I left off dressing him ; and in all other 
respects the horse is in good health. 
THE NARCOTIC AND SEDATIVE EFFECTS OF 
OPIUM. 
By Mr, J. Younghusban d, F.S., Greystoke. 
A grey horse, four years old, the property of Mr. G. W., 
was attacked, on the 8th of April, with what was supposed to be 
flatulent colic, but, the case not being considered desperate, it 
was treated by the owner. The symptoms at length becoming 
materially worse, I was requested to attend him as soon as pos- 
sible. When I arrived, I found him with all the symptoms of 
enteritis in a sub-acute form ; his pulse small and weak, beat- 
ing upwards of 100 in a minute, and the bowels being con- 
stipated. As he had already been bled by the owner, and the 
state of the pulse (according to my opinion) not warranting any 
further depletion, I forbore to abstract any more blood at that 
time, but immediately prepared an anodyne mixture consisting 
of tinct. opii., spt. ether nit., and a solution of aloes ; I also threw 
up an injection of warm water in which a little salt was dissolved. 
This was immediately returned without being in the least tinged 
with any faecal matter. Waiting awhile to see whether there 
would be any effects from the draught, and the horse perspiring 
very much in the intervals of ease, which were short, i had him 
well rubbed, and dry clothing put on. 
An hour having elapsed and the pain not abating, and at the same 
time the horse appearing to get weaker, I determined to abstract 
more blood; but after having withdrawn about six pounds, the 
animal appeared inclined to faint. I then pinned up the orifice, 
gave a draught of tinct. opii. and spt. nit. without the aloes, and,
