is but 89.0. Either the capacity in the males is relatively siibmedium 

 or that in the females relatively above medium. There are indications 

 that would seem to sustain the latter deduction, but a real conclusion 

 is not yet possible 



The relation in the two sexes between the capacity and the mean 

 cranial diameter is of special interest. This relation in all the groups, 

 and in man in general is distinctly lower in the females than in the 

 males. I have pointed this out on several occasions. The reason for 

 this is not yet clear, but it is doubtless connected with differences in 

 the two sexes in the development of certain parts of the brain — the 

 contents of the fossae and perhaps of the base of the brain — in the 

 two sexes. 



FACIAL INDICES 



The facial dimensions of the Eskimo are among the largest known in 

 human groups, and both the indices are rather high, indicating a 

 relatively high face. There are individual Eskimo crania, especially 

 on St. Lawrence Island, in which the face is very high indeed; but 

 there are also others in which the facial height relative to the great 

 breadth of the skull is moderate. The indices in our different groups 

 follow:
