and disposed to ulceration, that the disease, nine times out of ten, 
re-appears. 
In the Newfoundland dog, canker on the ear assumes the form 
of a superficial ulcer, sometimes on the inside, but oftener on the 
outside, near the top of the ear, and not penetrating to the carti¬ 
lage. It seems to be exceedingly painful, and yields only to the 
ointment of the nitrate of silver, assisted by confining the ears 
with a cap. 
Spaniels have frequently a mangy inflammation of the edges of 
the ear. It does not run on to canker, but the hair comes off 1 
round the edges of the ear, accompanied by much scurfiness and 
thickening of the skin. The common sulphur ointment, mixed 
with an eighth part of mercurial ointment, will speedily remove 
this affection. 
From the irritation produced by canker in or on the ear, and 
the constant flapping and beating of the ear, there is sometimes a 
considerable effusion of fluid between the integument and the car¬ 
tilage, and occupying the whole of the inside of the flap of the 
ear. The only remedy is, to open the enlarged pait from end to 
end, carefully to take out the gossamer lining of the cyst, and then 
to insert some bits of lint on each side of the incision, to prevent 
its closing too soon. In a few days the parietes of the cyst will 
begin to adhere together, and a perfect cure will be accomplished. 
If the tumour be simply punctured, the incision will speedily 
close, and the cyst will fill again in the space of four and twenty 
hours. A seton may be used, but it is more painful to the dog, 
and slower in its operation.

Gentlemen, 
Although of old—I might almost say, ancient —date, I have 
ventured to send you the annexed account of a case that never 
occurs in our practice without interest; and I trust it will turn 
out an acceptable one. 
On the morning of April 25th, 1805, the subject of the present 
case was taken unwell with symptoms of ordinary gripes, for 
which he was treated by venesection, turpentine drenches, &c. &c. 
but without relief: for he continued lying down and rising again 
every minute; he sweated profusely from pain; his pulse was 
small and quick, and at times scarcely perceptible at all. Lau¬ 
danum was afterwards had recourse to; but with little if any
