We give here the averages of the various measurements taken on I., StlEmqo'- 

 lEqumQ men ; II., StlEmqo'lEqumQ women ; III., Chilcotin men. When 

 "we call A the averages and E the mean errors, we find : — 



The difierences between these averages are throughout slight. In 

 order to show the comparability of the measurements still more clearly 

 we give here the values of the differences and their errors, and the average 

 difference and its error for each measurement which have been obtained by 

 weighting the individual differences. 



Differences between Measurements taken by Boas and Farrand and their JErrors. 



It appears from this table that the measurements are strictly compar- 

 able, and that the personal equation may be neglected. 



The tribes which were principally studied are the Northern Shuswap, 

 the Lillooet, the Chilcotin, and the northern tribes of the coast. The 

 Shuswap are divided into divisions in a manner similar to the divisions of 

 the Ntlakya'pamuQ. We have collected measurements of the StlEmqo'- 

 lEqumQ, the division of the tribe living on Fraser River, north of the town 

 of Lillooet, of the Sti'atEmQ of North Thompson River, of the Shuswap'o'e 

 of Kamloops, and a few of the group inhabiting Buonaparte River. We 

 have treated the Lillooet of Fraser River, who are mixed with Shuswap, 

 and Ntlakya'pamuQ separately from the purer groups of Seton and Ander- 

 son Lakes. Following are the tables of measurements : —
