C18 FISTULOUS PAROTID DUCT IN A YEARLING COLT. 
of the brewery in this town, that had a small wound on the 
side of his neck. I was told that about four months ago, he 
got his head fast in between the u boosy stake” and a board, 
and that in the course of a month after, a large abscess 
formed in, or in the neighbourhood of, the parotid gland, and 
had left the present opening. The gland is now of its natural 
size, and healthy. The opening is situated at the upper angle 
of the off jaw, near to the lower part of the gland. The dis¬ 
charge is but slight, and is of the consistence of pus, more 
than of the supposed slimy salivary secretion. From the 
nature of the accident and the time it has existed, I was in¬ 
clined to believe it was a fistula of the parotid duct. I put 
a tent of Ung. Hyd. Bichlor. in it, and on the 30th, I put in 
another. 
May 1 st .—Injected the aperture, and could plainly hear 
the fluid gurgling into the mouth. 
3d. —It is discharging more than it did; but still the issue 
is not of that slimy nature that I should have expected it to 
have been. It has no bad smell. Applied the cautery. 
4 th. —Still discharges. Cleaned the orifice, and passed a 
thread suture from side to side, and drew the opening close, 
and blistered around it. 
Qth. —Suture broke out. 
7 th. —Discharging. Apply cautery. 
11 th. —Discharging. He has been kept up; but as the 
opening continues to discharge, he was this day turned out 
again, and directed to be left alone, to see if the sinus will 
close. 
\Mh. —Has been out at grass since last date, and now 
appears as if he was not well in health; he seems dull, and 
staggers about as if affected in his head and spine. 
The throat and parotid gland I almost fancy are a little 
sore, though nothing of much moment. The owner believes 
he is u out of sorts” from my applications. Some large long 
worms have come from him in his dung. Gave a dose of 
physic, which operated well; but no worms made their 
appearance. 
Q\st. — His slight staggering gait is better. This day Mr. 
Hales, V.S. of Oswestry, being up here in attendance on the 
North Salopian Cavalry, I got him to look at the colt. To 
prove that it was a fistulous parotid duct, I injected some 
bole and water, which shortly made its appearance in the 
mouth. The discharge is the same, and but small in quan¬ 
tity, even while feeding. From the quantity, colour, and ap¬ 
pearance of the discharge, Mr. Hales almost doubted whether 
it really was a fistulous parotid duct; yet he could hardly
