not work both ways — subjects with light hair and eyes do not always 

 or even very often have also a lighter than medium epidermis. 



On the other side of the " medium " we have the more or less 

 swarthy, dusky, or faintly tawny skins, and the correlation of hair 

 and eyes with these discloses some curious conditions. 



Correlation of color of hair and eyes ivith the color of the skin in Old Americans. 



DARKER SKIN. 



' Mostly "mixed" (blue or greenish or grayish with more or less marked traces of brown). 



The above shows that in the darker persons there exists a very 

 marked correlation between the color of the skin and that of the 

 hair. There are no " blonds " in the men or women with darker skins 

 and unexpectedly also no " reds," which points to a rather close 

 relation of these shades; and there is a very large proportion of 

 darks to black. Also, throughout, there is an evident tendency 

 toward more darkness of hair and eyes in the females than in the 

 males, which, however, as will be shown below, does not apply alone 

 to this class of cases. 



As to the eyes, the correlation of their color with that of the skin 

 is plainly less than with the hair. A good proportion of both men 

 and women with a darker skin and dark hair have blue, greenish, 

 gray, and especially mixed eyes ; but there is also a considerable pro- 

 portion of browns, much above that in the Old Americans at large. 

 The women show again a greater tendency in this direction — they 

 have less " lights " and light browns, but decidedly and progressively 

 more medium and dark browns. Why this should be so is not yet 

 quite clear, but we shall return to the phenomenon, which seems to be 

 generalized among all whites, on another occasion. 



The above correlations between brunet skin and the color of the 

 hair and eyes may be shown still more clearly by comparing the 

 percental representation of the different classes of shades of the hair 

 and eyes in those with swarthy skins to the whole number of subjects 

 in our series:
