Minimum Frontal Diameter. 



(a) Dolicho-cephalic crania, -~ fourteen. — In all cases the 

 right segment was larger than the left by amounts which varied 

 from 1 mm. to 5 mm., the average difference being 2.4 mm. 

 This constancy in favour of the right side contrasts distinctly 

 with the variability formerly noted among the crania of the 

 Aboriginal Auslralians, and moreover the average difference is 

 less among the Scandinavian crania than it was among those 

 crania of the Aboriginal Australia ns in which the right segment 

 predominated. 



(b) Brachy-cephalic crania, — five. In this set the right 

 segment again held the advantage throughout, although it was 

 only to the extent of 1 mm. except in the case of one skull 

 (283) in which the right segment was 5 mm. larger than the 

 left segment. The number is small for the purpose of stating 

 an average, but if we do so for the sake of a comparison, it 

 gives 1.8 mm. as the average excess of the right segment. In 

 the brachy-cephalic crania of Sandwich Islanders which I have 

 formerly examined, the average excess of the right side was 

 3.2 mm. 



(c) Mesati-cephalic crania, — five. In four cases the excess 

 was on the right side, giving an individual variation of from 

 1 to 4 mm. with an average of 1.25 mm. In a single skull 

 (353) probably female, the left segment was 1 mm. greater than 

 the right. 



From these figures it is evident that in the frontal region 

 not only is the average difference which indicates asymmetry 

 small, but it is distinctly smaller than among the savage crania. 

 Further the individual asymmetry was in most cases so very 

 small as to be practically of no importance. Only in three 

 crania out of the twenty-four did it amount to 5 mm. Among 

 these Scandinavian crania therefore the approximation to exact
