common. Excepting where the deafness is due to accumulations which can be 
removed, the results of treatment so often prove negative that it is therefore 
not encouraged. 
ABSCESS OF THE AURICLE. 
Occasionally blisters form on the ear-flap, and commonly in consequence of 
blows or tugging at the ear. The violent and constant shaking of the head 
induced by otitis may also excite them if the victims have long and heavy flaps. 
They have the baggy appearance peculiar to all blisters, and contain a thin, 
watery fluid at first. If, however, proper treatment is not promptly applied, their 
contents thicken, to become yellowish ; and then the blisters are converted into 
abscesses. 
An opening of fair length should be made at the lowest part of the blister, 
and its walls pressed together, to cause them to unite readily. If they fail to do 
this, and ulceration occurs, to be followed by a running sore, it should be treated 
with the oxide of zinc ointment. 
BLOOD TUMOR OF THE AURICLE. 
Othzmatoma or blood tumor occasionally appears in dogs, and is commonly 
the result of blows or violent flapping of the ear. It is sometimes of small size, 
but now and then cases are met with in which the tumor covers nearly or quite 
the entire inner surface of the auricle. 
The proper treatment is to pass a needle, threaded with white silk, in and 
out of the tumor at its lowest part, and tie the latter so it cannot slip out. 
By these means there will be two small openings which cannot close, and the 
contents of the tumor will be evacuated and keep drained off. 
A piece of sheet lead should be cut as nearly as possible to the shape of the 
tumor. This, used as a compress to keep the walls of the empty sack together, 
assists it to unite. With holes at its various corners, it may be carefully adjusted 
over the tumor and then stitched to the ear, the needle being driven through 
the holes and ear-flap and back again, and the silk tied — but not too tightly. 
WOUNDS OF THE AURICLE. 
A tear of the flap of the ear, even if it is only a small one, often proves to be 
intensely troublesome. The flap as a whole is highly vascular, or in other words,
