HBDLICKA] SKELETAL PARTS 315 



The first fact shown by the preceding figures is the slightly greater 

 length of all the long bones in the midwestern and northwestern 

 groups as compared with those of the Bering Sea (midwestern and 

 southwestern). This means naturally that the people of the Seward 

 Peninsula and northward average somewhat taller in stature. 



The second evident fact is that the people of the Seward Peninsula 

 and the more northern groups (so far as represented in these collec- 

 tions) show a slightly greater stature of all the bones than the 

 groups farther south, showing that they were both a somewhat taller 

 and somewhat sturdier people. 



The next fact of importance is the remarkable agreement in some 

 respects in the relative proportions of the main skeletal parts be- 

 tween the people of the more southern and the more northern groups. 

 The males are more regular in this respect than the females. The 

 relative proportions of the humerus and again the tibia at their 

 middle are identical in the males of the southwestern and midwestern 

 groups and those farther northward ; and the radio-humeral, humero- 

 femoral, and tibio-femoral indices are all very closely related. Why 

 there should be less agreement in these respects among the females 

 it is difficult to say; in all probability the series of specimens are not 

 sufficiently large. 



The next table presents data and some racial comparisons. Here 

 the western Eskimo are taken as a unit. They are seen to consider- 

 ably resemble the Yukon Indians, but somewhat less so other Indians 

 in the radio-humeral and tibio-femoral indices, and they resemble all 

 the Indians in the relative proportions of the femur at its middle. In 

 other respects there are somewhat more marked differences, especially 

 between the western Eskimo and the Indians in general. Some irregu- 

 larities in the Yukon series may be due to insufficiency of numbers. 



When compared with the bones of the whites and the negroes the 

 Eskimo and Indians separate themselves in many respects as a 

 distinct group, while the white and the negro bones are particularly 

 distinct through the greater relative thickness of the humerus and 

 tibia at their middle, and of the femur at its upper flattening; in 

 other words the Eskimo as well as the Indians are more platybrachic, 

 platymeric and platycnemic than the whites or the negroes. 



The basic relation of the Eskimo to the Indian bones is quite evi- 

 dent ; though the Eskimo, when compared to Indians outside of 

 Alaska, show a relatively shorter radius and tibia, indicating the 

 already discussed relative shortness of the forearm and leg. 



Long Bones in Eskimo and Stature 



One of the most desirable of possibilities in the anthropometry of 

 any people, but particularly in groups now extinct, is a correct esti-
