FISTULOUS PAROTID DUCT.

peared very small; its border was circular and smooth, and was 
red or pinkish, from having no cuticular covering. Pure saliva 
•was emitted from it, which, from trickling down the cheek, wetted 
the hair, and in places excoriated the part. The issue was not 
constant: eruptions commonly took place twice in the course of 
the day—at eleven o’clock in the forenoon, and four in the after¬ 
noon, at which hours he was fed with com ; which, in consequence 
of its requiring greater mastication than other provender, would 
produce more copious emissions. At first, the fluid spirted out 
in a fine stream for the distance of three or four yards from 
the head, bespattering the side of the stall; at which time from 
two to three drams might be collected in a tea-cup per minute. 
Soon, however, the stream decreased, and gradually degenerated 
into droppings, which fell, during the time he was eating his com, 
in quick succession from the side of his face into the manger. 
Conceiving pressure likely to prove effectual, I procured one of 
Salmon’s patent trusses, and applied it around the fore part of 
the head, with the pad pressing firmly upon the orifice. This 
had more effect than any ordinary bandage could have had, and 
was unattended with any confinement of the jaws : it however 
occasioned so much annoyance in pressing the soft parts against 
the molares, that the animal at length refused to eat with it on; 
whereupon its use was discontinued. I ought to have mentioned, 
however, that, finding the orifice of the duct closed internally, I 
made a perforation through the cheek prior to the employment of 
the truss. 
Next I tried ligature of the duct. I cut down on the duct as 
it ascends upon the face around the border of the lower jaw, and 
fastened around it a double ligature well waxed, leaving the ends 
hanging out of the wound between the sutures employed in closing 
it. I found the duct so much enlarged, that I at first mistook it 
for the sub-maxillary vein. Eight hours aftenvards, the duct, as 
large as my fore finger from distension, was distinctly apparent 
under the skin, all the way from the ligature to the gland : the 
gland itself was also much swollen, and evinced tenderness on 
pressure. 
2d Day ,—The duct distended even to bursting; the gland 
enormously swollen, and very tender. The side of the face puflbd 
a little. Appetite unimpaired. 
3d Day ,—The duct has acquired a firmer feel; gland not so 
tender, a little pus appearing at the orifice of the wound. The 
stitches were cut. Liq. Plumb, to the face, which is ratlier more 
tumefied. Bol. Purg. 3vj. Fed on green meat. 
4th Day ,—Much the same. He purges. Pus drops from the 
wound.
