The figures show no characteristic (hfl'erence in the relation of 

 force in women to that in men in tribes of widely diverging average 

 statures. 



The pressure force in the females equals, it is seen, in the right hand 

 from 54 to 66, in the left hand from 53 to 73, per cent of that in the 

 males in the same hands. In half of the tribes the differences in the 

 left hand are less than those in the right, pointing to a relatively 

 greater strength in the left hand in the women of these tribes. This 

 point will be brought out more clearly in a subsequent paragraph. 



There is a much greater difference between the two sexes in traction 

 force than in ])ressure, owing to a greater variation in this respect in 

 the women. This test gave abnormally low results in the Tarasco 

 and the Aztec women. 



It might be objected to the above table that, since in some tribes 

 more of the older individuals were examined than in others, it includes 

 groups of varying average age, to which fact may be due some of the 

 variation. In consequence, a similar table w^as made of individuals 

 of the same tribes, but ranging only between 20 and 30 years of age:

It will be noticed that there are only a few differences, in compari- 

 son with the data shown in the preceding table; and that in a num-
