ing were read and approved. The application of Dr. F. Lock-

REGULAR PROGRAMME. 
Dr. Frank Allen presented his paper on “ Dental Cysts, 
Deafness, Paralysis of the Ear, Tumors in Cartilage of the Ear, 
Fistula and Meniere’s Disease,” as follows : 
Dental Cysts .—These may be found in all parts of the body, 
but generally in the sinuses of the head and near the base of 
the ear. They consist of a membranous sack containing de¬ 
veloped or partially developed teeth. They would, in my 
opinion, constitute an nnsonndness, necessitating a surgical 
o]3eration for their removal, although many animals pass through 
life without one and are still serviceable. 
Deafness. —This, from whatever cause, whether congenital 
or accidental, is a decided unsoundness. The causes of deafness 
in a horse are numerous and not well understood. Since the 
overhead trolley wires have been in existence I have come across 
several cases from severe electrical shocks. 
Paralysis. —This, although a great disfigurement, I should 
hardly call an unsoundness, as a horse with paralysis of either 
one or both ears is just as good for service as a horse without. 
I should consider it a bad blemish, but not unsound. 
Cartilage (Enchondromata).—These tumors, if they 
should grow from the cartilage of the ear, although I have never 
seen one, I should consider them a decided unsoundness. Judg¬ 
ing from my experience with them on the sternum, where I be¬ 
lieve iinless operated upon at a very early stage, they are incur¬ 
able, and they seem to grow again faster than ever after being 
removed. 
Fistula .—This is an unsoundness, in my opinion, necessitat¬ 
ing a surgical operation. I have come across two of them re¬ 
cently, both passing from the inside of the conchal cartilage, 
running downwards and forwards about four or five inches. 
They both healed up nicely after being curetted out. I believe 
a common cause of these to be the use of a twitch on the ear.
