Tibia. The tibiae in both cases are quite normal, although in 

 5863 the oblique line is strongly developed and the entire surface 

 slightly roughened, as in the femora of this specimen. The length 

 of the tibiae of 5864 is somewhat above the average for white males, 

 although that of 5863 is slightly below the figures given for white 

 females. In the former the right tibia is 8 mm. longer than the 

 left. The tibio-femoral index was above 84, thus showing a greater 

 proportional length of tibia than in the Smith sound group, or even 

 whites. The anterior posterior diameters were also found to be 

 somewhat greater than for whites of corresponding sexes. This 

 shows a considerable variation from the Smith sound group, in 

 which they were less. On the whole, it seems that the Alaskan 

 Eskimo have much longer and stronger legs than their eastern 

 relatives, a difference which can be easily accounted for by their 

 habit of taking long hunting expeditions on foot, and by their use 

 of the roomy umiak instead of the kayak, which cramps the legs. 

 A more certain and plentiful supply of food during the period of 

 growth may also be an important factor in insuring a good develop 

 ment of the long bones.
