RELATIVE f REQUENCY

BRUNEI JRAITS. 



Fig. 8. — Map of southwestern Europe showing the relative frequency of 

 ''brunet traits," e. g., brown eye color. On the whole, the darker the shade 

 the greater the proportion of brunet persons in the given area. The lightest 

 areas represent about 20 to 25 per cent brunetness; the darkest European 

 areas over 90 per cent brunetness. At the northern limit of the map "about 

 one third of the people are pure blonds, characterized by light hair and blue 

 eyes;" on the other hand, in the south of Italy the pure blonds have almost 

 entirely disappeared. From W. Z. Ripley: "The Races of Europe."
