are but moderately high, like those of the southwestern Eskimo. The 

 northern Arctic skulls give smaller height than would be expected 

 with their type; the Southampton Island specimens give higher. 

 The old Igloo group from near Barrow stands again close to Green- 

 land; its skull is even a trace narrower and higher, standing in both 

 respects at the limits of the Eskimo. The whole, as with the cranial 

 index, shows evidently a rich field of evolutionary conditions.
