companied with a view of the open mouth, &c. 
to shew the situation and form of the teeth. I 
must here observe, that the figure represented in 
the Journal de Physique, though a good general

long hair of the head. It is totally destitute of 
incisores or front-teeth : in each jaw are two ca- 
nine-teeth of a moderate size : those in the upper 
jaw are situated at the distance of two inches 
from each other ; those in the lower jaw are placed

in the upper jaw are placed three on each side; 
of which the two most remote are double or lobed :

are on each side six grinders, of which the most 
remote or backward is simple; the two next

The tongue is smooth, and has nothing remark-
