iv.] SCHEMES OF DISTRIBUTION AND OF FREQUENCY. 43 



both the ratios and the differences between either pair of 

 values would be sensibly the same. 



A different way of comparing two Schemes is some- 

 times useful. It is to draw them in opposed directions, 

 as in Fig. 5, p. 40. Their curves will then cut each 

 other at some point, whose Grade when referred to 

 either of the two Schemes (whichever of them may be 

 preferred), determines the point at which the same 

 values are to be found. In Fig. 5, the Grade in the 

 one Scheme is 20° ; therefore in the other Scheme it is 

 100°- 20°, or 80°. In respect to the Strength of Pull 

 of men and women, it appears that the woman who 

 occupies the Grade of 96° in her Scheme, has the same 

 strength as the man who occupies the Grade of 4° in his 

 Scheme. 



I should add that this great inequality in Strength 

 between the sexes, is confirmed by other measure- 

 ments made at the same time in respect to the 

 Strength of their Squeeze, as tested by another of 

 Salter's instruments. Then the woman in the 93rd and 

 the man in the 7th Grade of their resective Schemes, 

 proved to be of equal strength. In my paper ■ on the 

 results obtained at the laboratory, I remarked : " Very 

 powerful women exist, but happily perhaps for the 

 repose of the other sex such gifted women are rare. 

 Out of 1,657 adult women of all ages measured at the 

 laboratory, the strongest could only exert a squeeze of 

 86 lbs., or about that of a medium man." 



1 Joum. Anthropol. Inst. 1885. Mem. : There is a blunder in the para- 

 graph, p. 23, headed "Height Sitting and Standing." The paragraph 

 should be struck out.
