REPORTS OP CASES.

During the month of September, Dr. A. S. Leatherman con¬ 
demned in the same vicinity two other horses, situated ten miles 
apart, both of which were brought from Canada by the same 
dealer, and belonged to the same drove with the horses Ned and 
Bill. They had all traveled in the same car. 
There is no difficulty in tracing the infection of the horses of 
Mr. K-, but for Ned and Bill and the two others, destroyed 
by Dr. Leatherman, the question may be asked, whether they did 
not become infected through the bad condition of the truck 
in which they were imported ? 
IRREGULAR WEARING IN THE MOLARS OF A HORSE.—NECROSIS 
OF THE PALATE BONE. 
Description of a Specimen presented by B. MoInness, Jr., Y.S., to the Museum of 
the American Veterinary College. By J. Sohrieblek, D.V.S., Curator 
of the Museum. 
The preparation exhibited was the head of an old horse which 
had been the property of an aged South Carolina negro. When 
death occurred the horse had become so emaciated that his ap¬ 
pearance was almost like that of an animal which had died of 
starvation. The condition of the teeth to a great extent explained 
this fact, and showed the difficulty the animal must have experi¬ 
enced in masticating his fodder. The molars of the left side on 
both jaws were about normal, but those of the right presented a 
very peculiar aspect, due to an irregularity in the wearing process, 
which, instead of taking place flatwise, had affected the teeth in 
their length. Those of the upper jaw were worn from above 
downwards, and from the inner side outwards, in such a manner 
that while the outer surface of the teeth measures over two inches, 
the inner surfaces measures scarcely half an inch, this being about 
the normal length of the teeth. This irregularity is perfectly 
smooth on the inner surface for the first four molars, but irregular 
on the fifth, which is angular. These teeth and the last have un¬ 
dergone less wearing. On the same jaw the palate bone was already 
undergoing necrosis, and showed in the center a perforated appear¬ 
ance and a depression towards the back. This condition of the 
palate bone is due to the action of the molars of the lower jaw.
