massive faces. On none of these points, however, have 

 investigations boon made and it is an open question 

 whether anything would be accomplished thereby other 

 than the definition of minute differences. In historical 

 times, at least, there was a great deal of intermarriage 

 and visiting between these tribes which must have 

 tended to level down somatic differences and which 

 makes the successful determination of genetic relation- 

 ship quite improbable. As to head form, we find an 

 index of about 80 for the Ute, Cree, Dakota, Blackfoot, 

 Cheyenne, Arapaho, Pawnee, and a considerably higher 

 value for the Comanche, Osage, Omaha, Wichita, and 

 Kiowa. 



The children of the Oglala division of the Teton- 

 Dakota have been measured from year to year by Dr. 

 J. R. Walker and a comparison of their averages and 

 rates of growth made with white children. In general, 

 there seemed to be no important differences, though the 

 Olgala children were uniformly taller than white 

 children as measured. 



On the whole, it cannot be said that the Indians of 

 this culture area are anatomically distinct from those 

 occupying some other parts of the continent. A map 

 showing the distribution of physical types in North 

 America would bear little resemblance either to the 

 linguistic or cultural map. On the other hand, there 

 seems to be a tendency toward uniformity throughout 

 the Plains but due more to the fact that these tribes 

 are for the most part a portion of a much larger somatic 

 group.
