sexes in all respects except in so far as pressure force among the 

 boys is concerned ; in this last-named characteristic the Pima youth 

 are superior. 



Of special interest are the hand-pressure results obtained from left- 

 handed individuals. It was found that among the 13 left-handed 

 Apache the right hand was stronger in 5, the left hand in 8, and 

 among the 9 left-handed Pima children the right hand was stronger 

 in 2, the left in 7. On the other hand, there were a number of right- 

 handed children in whom the pressure force in the two hands was 

 equal, and in 12 right-handed Apache and 7 Pima the left hand was 

 the stronger. The cases are given in detail below. The irregulari- 

 ties agree with what was before observed by the writer as the result 

 of investigations among the white children of the New York Juvenile 

 Asylum.'^

 able in so far as it concerns the period near puberty; it is known 

 that, at this time, white girls surpass the boys in both stature and 

 weight.
