THE GLENOID FOSSA IN THE SKULL OF THE ESKIMO. 
13 
We are likely, I think, to find the same condition in any 
race or section of any race where the food is soft, either owing 
to its nature or the method by which it is prepared for consump- 
tion, and this whether the race is ancient or modern, primitive 
or civilized, white, black, or brown in colour. It seems to be 
simply a question of diet and cookery. Again, it is likely 
that even in members of the same race marked differences may 
be found, due to local conditions of diet, and it is quite probable 
too that, for instance, members of the same tribe may differ 
to a certain degree owing to individual characteristics. Still, 
I think the broad fact remains that in any race or in any ethnic 
group where the food or method of preparing it is such that 
strenuous mastication is required, the glenoid fossae of the 
individuals constituting that race or group will in general display 
a shallowness not met with amongst peoples enjoying softer 
conditions of diet.
