COMPLETE OBSTRUCTION OF THE STENON DUCT.

This being a purely local trouble, his pulse and temperature are 
not much altered. 
June 12th.—The presence of pustules are already discernable 
by fluctuations in a number of spots along the swelling. These 
are accordingly evacuated. The discharged pus is of an offensive 
watery character, commingled with gases and debris tissue—a 
typical gangrenous condition. 
June 13th.—Swelling decreasing, and pustules more nu¬ 
merous. 
June 14th.—To-day I discover the origin of this trouble, which 
is nothing more than the presence of the top of a spear of timo¬ 
thy hay, lodged within the Stenon duct, at its entrance into the 
mouth, opposite the upper third molar on the left side. This 
obstruction I removed with ease, by taking hold of its short stalk 
and drawing it out, it being well saturated with offensive mucous, 
having the appearance of being lodged there a number of days. 
The seeds easily dropped off after being exposed to the air. 
June 15th.—The destructive process seems to have reached its 
maximum. Suppuration is well established, and the swelling is 
diminishing rapidly. Sloughing of the skin over the entire left 
parotid gland is going on. Prehension and mastication are car¬ 
ried on with more ease. 
June 18th.—All the dead tissue has by this time exfoliated, 
leaving a clean wound, studded with healthy granulations. 
June 22d.—Suppuration is considerably checked. The healing 
of the wound is quite obvious. The horse is annoyed somewhat 
by the collection of food between his upper left molars and cheek. 
These quids, however, are easily displaced by means of a flat 
stick (a sweat scraper) whenever it becomes necessary. 
June 25th.—The patient is discharged in a fair way of recovery. 
Instructions are given to perfect the closure of the wound. 
Case No. 2 is a grey gelding of about fifteen years of age. 
He is brought to my hospital Dec. 3, 1884. The right side of 
his head is greatly swollen, involving the base of his ear, the 
parotid and buccal regions, also the orbital process to such an ex_ 
tent as to almost close his right eye. This swelling has been in 
progress for two days. I immediately made an examination of his
