Individual group differences in the facial and alveolar angle are 

 moderate, yet evidently not negligible. (See next table.) The most 

 prognathic, especially in the subnasal region, are the skulls from 

 Nelson Island. A marked alveolar slant is also present in the Pilot 

 Station Yukon group, and in Greenland. The least prognathic are 

 the St. Michael Islanders, the Point Hope people, and those from 

 Southampton Island. St. Lawrence stands once more near the 

 middle of the southwesterners and midwesterners, and there are to be 

 seen the principal old relations. 



The main points shown by the above conditions are the group 

 variability, particularly in the southwest and midwest; the tendency, 

 on the whole, toward a slightly greater prognathy, both facial and 

 alveolar, in this same area; and the evidence that the alveolar slant 

 has some individuality.
