Thus far we examined redhairiness with regard to the increase 

 or decrease of the number of blondes among our population, and we 

 came to the conclusion that the two phenomena are independent ot 

 each other. We can now look upon the phenomena from another 

 point of view. If it were true that redhairiness showed a preference 

 for the blond race, the consequence of this must needs be that among 

 the children who, as to pigmentation, belong to the blonde race, ac- 

 cordingly such as have blue or grey eyes, there are more redhaired 

 individuals than among those with brown or brownishgreen eyes. 



How far this is true is shown by Table III. 



TABLE III. 



The first column mentions the total number of children with one 

 of the four different iris-colours, and in the four following columns 

 we find consecutively the percentage of the combination of the iris- 

 colour with one of the four haircolours. Phenomena make them- 

 selves manifest therein, which were to be expected beforehand. Of 

 the blue-eyed individuals for example, 83 % have blonde hair, of the 

 brown-eyed only 45 % ; on the other hand the number of brown- 

 haired persons with the last is more than three times as large as 

 with the blue-eyed, and a relatively still stronger rise is found with 

 the blackhaired. Generally speaking, it appears that with an increase 

 of the pigmentation of the iris also the pigmentation of the hair 

 increases. "This holds good for blonde, brown and black hair. But in 

 contradistinction to this there appears to be no relation between the 

 degree of pigmentation of the iris and the hair with redhaired in- 

 dividuals. For of the blue-eyed 2.47 % are redhaired, of the grey- 

 eyed 2.63 °,' , of the brownish-green-eyed 2.55% ar >d of the brown- 

 eyed 2.03 %■ I* IS true, this last figure is the lowest, but it seems 

 to me that the difference is not so great that therein the proof may 

 be seen that redhairiness shows less relationship to the brunette race. 

 Moreover, this opinion could directly be refuted by the fact that I
