CLINICAL CHRONICLES.

Mastication was very painful, as it could only occur on the off- 
molars, and deglutition was interfered with by the median posi¬ 
tion of the posterior molars, preventing the freedom necessary at 
the base of the tongue, where a loose rattling or crepitation 
could be heard. 
In the presence of the condition of the patient, the excessive 
growth of the teeth and the diseased condition of the maxillary 
bones, a most unfavorable prognosis was given, and the animal, 
abandoned by his owner, was destroyed. 
Post Mortem Examination. —The muscular structure of both 
cheeks being cut through, the lower jaw was separated from the 
upper, and the following unique lesions exposed : The mucous 
membrane of the buccal cavity offers numerous severe excoria¬ 
tions, especially toward the roof of the mouth, which is much 
lacerated by the sixth molar, while within a short distance of the 
median line, there is a seventh supernumerary molar (both of 
which were so loose that they fell out on the slightest traction.) 
They had punctured a hole through the palate bone into the nasal 
cavity, through which food found its way into the air passage. 
This seventh molar was three inches long and had an additional 
curious fang, nearly out, long, loosely held in place, and moving 
at every motion of the inferior maxillary bone. The last alveolar 
cavity had a large necrosed hole in the bone, due not only to the 
disease of the bone, but to the leverage exerted by the superior 
molars, which were grown down. This cavity contained about 
eight ounces of imperfectly masticated and decomposed food. 
Each dental molar arch contained seven fidly developed 
molars. 
After boiling, the incisors were found curving straight for¬ 
ward, then bending slightly downward, and were very much 
elongated. The palatine bone had a triangular notch necrosed on 
its border, a little to the left of the median line, with a rough 
and irregular border. The bones of the forehead are much 
softer and when dry are easily broken, on account of their brittle 
condition.
