ANTHROPOLOGICAL SURVEY IN ALASKA 



[ETII. ANN. -16 



The group differences in the orbital index of the Eskimo skull are 

 shown in the next table. They elude a satisfactory explanation, un- 

 less recourse is had to the above suggested theory of normal group 

 variability within a family. They have about the same range in 

 the three large areas, which would seem to support this theory. 



Group relations are indicated in the cases of Pastolik- Yukon Delta- 

 St. Michael Island; Point Barrow-Barrow; and Old Igloos-Green- 

 land.
