FISTULOUS PAROTID DUCT IN A YEARLING COLT. 619 
think it could be anything else. He advised it to be occa¬ 
sionally injected with gr. v (of Argent.Nit. ?) to 3j of water; but 
as his head and spine had apparently been recently affected 
from some cause, I declined interfering with him for the 
present, and therefore left him out at grass. 
June 3d. —Is now in perfect health; in better condition; 
and has in a great measure shed his old coat. There is still a 
slight discharge from the orifice, of a brownish tint, and of a 
mucous feel, and I should really think it was from the gland. 
According to PercivalPs formula, I made an injection of 
Argent. Nit., 5 SS; Acid. Nitric., 5 j ; Aquae, I got m y son 
to place his finger on the duct as well as he could, about 
where the pulse is felt, whilst I injected about half the injec¬ 
tion. A good deal, I think, passed into the mouth; but I 
kept forcing it in for about two minutes, and some, no doubt, 
passed into the gland. 
7 th .—The injection seems to have had no effect upon the 
gland, as it is not in the least swollen. Discharge about the 
same. Injected an ounce more, and turned him out. 
10 ^.—Neither glands nor surrounding parts have in¬ 
flamed in the least. There is scarcely any discharge at the 
orifice; it seems plugged up; perhaps, with a slight slough. 
\QtJi .—The hair below the wound is matted together; but 
there is scarcely any discharge from the orifice, which is very 
small I fancy it will close up. Injected it as before, when 
some came out at the mouth. 
19^.—The opening is larger, as if from sloughing. Once 
more injected it as before. 
20 th .—The opening and discharge are about as usual; 
not the least better. 
July 1st. —Just the same as ever. I could put a crooked 
probe into the opening, and pass it in a downward direction 
for two inches or so. Seeing no probability of doing any 
good by continuing the injections, I now passed two pins 
first on each side of the orifice, and then drew a metallic liga¬ 
ture around them, in a similar way to treating exomphalus, 
and turned him out. 
2 ^/.—The ligature was on, this day in the evening. 
3d. —At night, it was out; by some means, and most likely 
by rubbing with the toe of his hind foot, he had got it out; 
or, he might have rubbed his neck against something. 
4 th. —At night, I saw him for the first time after I had 
put the ligature on, and there was not the least appearance 
of inflammation of the parts as from injury by rubbing, but 
it was just the same as when I put it in. The orifice was 
nearly dry, and small.
