ARCHiEOLOGICAL AND ETHNOLOGICAL RESEARCHES IN CRETE. 245 



The smaller number of examples is accountable for the lack of dis- 

 tinctness in the association of age and hair-tint. I have no doubt but 

 that a longer series would show clearly that, as among the boys, the hair 

 darkens with age. Probably, also, the condition observed in this country 

 would also obtain — viz., that in the female sex the darkening never 

 becomes so marked as in the male. It is a matter for speculation 

 whether exposure to the open air has an influence here. 



As regards the association of eye-colour with hair-colour, the records 

 show that dark-brown hair is never accompanied (in this series) by eyes 

 .of lighter tint, although fair hair (especially, of course, in the younger 

 girls) may be found with dark eyes. 



II. The records of eye-colour have been summarised as follows :-—

The inspection of this table shows that the association of eye-tint 

 and age is just as indefinite as among the boys. As in the case of the 

 hair, we find here reason to suppose that the depth of pigmentation is' 

 less in the female sex. There may be a real sexual difference here, or 

 the result may be simply due to the more constant exposure of the males 

 (whether boys or men) to the weather ; and I incline to lay stress on the 

 latter consideration. 



III. Head-length. — The mean value of this dimension in 25 girls 

 (at Vori), of an average of 7 - 7 years, is 166'8 mm. Fifty-nine boys at 

 Vori provide an average of 173"9 mm., but the mean age of the boys was 

 9"9 years. We have seen that nine boys of a mean age of 6 years gave 

 an average measurement of 171 mm. Evidently the female head is 

 smaller in this dimension. 



IV. Head-breadth. — The mean value of this dimension in 25 girls 

 (at Vori) is 133"7 mm. The boys at Vori (59 in number) gave an aver- 

 age of 139'3, but their age is greater. Nine boys averaging 6 years of 

 age give a mean value of 135'4. From all this it appears that in child- 

 hood the female head is less broad than the male. 



V. The Cephalic or Breadth-index. — The mean value of this index 

 in 25 girls (at Vori) is 80T. Boys with a mean age of 6 years provide a 

 mean index of 79"2. All the boys taken together give 80'9 as the mean 

 value. So far, then, it does not seem a,s though the sexual difference
