ANTHROPOLOGICAL SURVEY IN ALASKA 



[ETH. ANN. 48 



An abstract of the data on the Eskimo skulls is given in the next 

 table. The values for the measurement are rather high, especially 

 for such short people. The percentage relation of the measurement 

 to the length of the skull appears also to be high. Manouvrier (1882, 

 quoted in Martin, Lehrb.. 716) found this relation in French skulls 

 to be 53.6 in the males and 54.7 in the females. 



Eskimo Crania: Basiox-Xasion Length 



The female measurement to that of the male, in the Eskimo, is 

 as 94-9 to 100. As a similar relation of the cranial modules in the 

 two sexes is close to 95.7, the anterior basal length would seem to be at 

 a little disadvantage in the female Eskimo skull. 



The same condition is seen also when the basion-nasion diameter 

 is compared with the length of the skull. In the males, notwith- 

 standing the fact that the length of the vault is increased through the 

 development of the frontal sinuses and not infrequently also through 

 that of the occipital ridges, the percentage relation of the basion- 

 nasion to the maximum total length of the vault is approximately 

 56.3, in the females but 55.8. It seems therefore safe to say that in 

 the Eskimo, in general, that part of the brain anterior to the fora- 

 men magnum is relatively somewhat better developed in the males 

 than in the females. 



But to this there are some exceptions. Thus it may be seen in the 

 general table which follows that in the northwestern groups condi- 

 tions in this respect are equalized; and in the succeeding detailed 

 table it will be noted that while the males exceed the females in this 

 particular in 14 of the groups, in 5 groups conditions are equal (or 

 within one decimal), and in 5 the female percentage exceeds slightly 

 that in the males. In the numerically best represented groups condi- 

 tions are nearly equal, with the males nevertheless slightly favored.
