REPORT OF CASE. 
animal very much swollen and protruding from the left side of 
the mouth. The owner said that the first he noticed wrong, was 
about three weeks previous, when a considerable swelling ap¬ 
peared on the left cheek; but the swelling nearly all went away 
in a few days, and he thought him doing well until four or five 
days, when he discovered that he had great difficulty in nursing 
from the mare and a very unpleasant odor in his breath. 
After casting and securing the colt, I proceeded to examine 
the mouth, first pushing the tongue back into the other side of 
the mouth, as he had but little use of it from its swollen and 
ulcerated condition. I passed my fingers into the mouth, and 
was somewhat surprised to find the corner nipper of the left 
inferior maxillary very loose; in fact, so loose that I picked it out 
with my fingers. I also discovered that the first and second mo¬ 
lars were loose, and I also picked those out with my fingers. In 
passing my fingers into their cavities, I found the maxillary itself 
in a state of necrosis, and the tissues covering the bone in a 
putrid condition. 
I told the owner that I could give him but little encourage¬ 
ment, but would remove the diseased portion of bone if he wished 
me to, and see what it would do. As the colt was a high bred 
one, and very valuable if cured, the owner wished his life saved 
if possible, even if he was left deformed. I then proceeded to 
remove that portion of the maxilla from the second nipper to the 
third molar, which I found perfectly necrossed and had to be re¬ 
moved in small pieces. I then supposed that I had all of the 
diseased bone removed, and thought that I would break off with 
the forceps some of the sharp joints of sound bone that would be 
likely to cause irritation. In doing this, I shortly discovered 
that the wdiole left inferior maxilla was detached from its perios- 
tium, and also from its ligamentous attachments to the superior 
maxilla. I continued to work carefully, cutting but very little, 
as the tissues were in such a putrid condition that the pieces of 
bone would easily tear through them, until I removed the whole 
left maxilla, the last piece being about as large as a man’s hand. 
I carefully washed out the blood and decayed tissue, and dressed 
with acidum carbol one part, water fifty parts, and ordered the
