FISTULOUS PAROTID DUCT.

parated, exposing the cellular substance underneath^ opaque and 
insensible. A linseed meal poultice is kept applied by a many¬ 
tailed bandage tied round the neck and in front of the head. 
BoL cont, alternis diebus, 
11th Day ,—The sloughing proceeds. A serous discharge emit¬ 
ted from the surface. 
Vith Dai /,—The sloughing is rapidly advancing. The un¬ 
covered chasm measures four inches by two. A copious sero- 
purulent discharge is emitted. The portion of gland above the 
chasm is still tumefied, and continues very tender to the touch. 
The appetite and spirits have remained unaffected. Cont. cata¬ 
plasm. et bol. 
17th Day ,—Large portions of gland have sloughed and come 
away upon the poultice: one yesterday; two to-day. The ad¬ 
joining surfaces appear healthy, and are seemingly only waiting 
for the separation of the remainder of the mortified parts to gra¬ 
nulate, and aid in filling up the vacuity. The discharge is now 
purulent, discoloured by the sloughy masses. The part of the 
duct remaining, between the angle of the jaw and the place where 
the fistulous orifice exists, becomes now filled with pus, which 
every morning is squeezed out. The animal’s general health con¬ 
tinues good. For these last three days he has been exercised. 
Cont. bol. and cataplasm. 
Day ,—A portion of gland having the shape and volume 
of an acorn, only being much longer, came away this morning in 
the poultice. The tumefaction has much subsided, and the ul¬ 
cerous surface bears a remarkably healthy aspect. Poultice is 
the only application. 
Day ,—To all appearances the entire gland has sloughed 
away. The chasm is granulating rapidly, and the surrounding 
border has evidently begun to contract. A genuine pus is co¬ 
piously furnished. The poultice has been discontinued for two 
days past, and the case treated as a simple healthy ulcer. 
33rf Day ,—Purulent matter is secreted within the duct, which 
remains, and, from lodging within it, distends it into a sort of 
pouch. Inject sol. cupri sulphat. 
43g? Day ,—The ulcer measures only two inches in its greatest 
diameter. Astringent injections have been used to suppress the 
suppurative action within the duct. 
l^th Day ,—The horse is ridden out upon the road. 
Day ,—Sore perfectly healed. No perceptible enlarge¬ 
ment or induration remains; there being only a shallow depression 
where the gland formerly was, which (unless it be pointed out to 
any person, in comparison with the opposite side) is unobservable. 
The horse continued in my possession two years afterwards,
