ABNORMAL DENTITION—IRREGULAR WEARING OF THE MOLARS ON 
ONE SIDE OF THE HEAD—NECROSIS OF THE MAXILLARY AND 
PALATE BONES. 
By Mr. T. S. Denslow (Student). 
At the clinic of the American Veterinary College, an inter 
esting case of abnormal dentition, in which forty-four teeth were 
found in the buccal cavity, was presented before the students. 
The animal was a chestnut gelding, 17 hands high, used for 
heavy draft, with a mouth showing the characters of an eight- 
year-old horse, but was much older. The incisors could not meet 
by a distance of at least five lines. Prof. Liautard recognized 
him as an old patient of his, one which he had attended to sev¬ 
eral times for the last twelve or fourteen years, he having been 
obliged to file his teeth several times in order to enable him to 
grind his food. The history obtained was that some six months 
ago he had numerous enlargements along the lymphatics of the 
head, which subsided ; that he had passed bloody urine at some 
various periods, and had also discharged blood from the nose. 
When presented at the clinic, he seemed in poor condition ; there 
was a very offensive discharge through the nostrils, slightly 
bloody, not sticky but somewhat adherent. When the mouth is 
opened there is an offensive odor of caries discerned at some 
distance from the patient. The mucous membrane of the nose is 
sound; the lymphatics of the intermaxillary space are swollen 
and painful. On opening the mouth, the molars of the left side 
presented a very peculiar abnormal aspect, their crowns not being 
opposed to each other, but the rubbing of the teeth taking place 
from the sides, that of the outside for the lower, and that of the 
inside from the upper teeth. The teeth were considerably over¬ 
grown, and their disposition was such that the jaws could only 
move vertically, no lateral motion being possible; prehension was 
very difficult, the animal grasping only a few blades at a time.
