20 DAVID HEPBURN. [No. 2. 



General Conclusions. 



I. BILATERAL SYMMETRY. 



(1) Minimum frontal diameter. Exact frontal symmetry 

 was not found in any one of the tvventy-four skulls, and 

 with one exception, the excess occurred on the right 

 side of the mesial plane; but the amount of difference 

 was so small as to indicate a greater approximation to 

 exact symmetry than among savage crania. 



(2) Stephanie diameter. No exact symmetry was found 

 at this diameter, and in the majority of cases the excess 

 occurred on the right side, although as a rule it was 

 less pronounced than among savage skulls. 



(3) Maximum parieto-squamous breadth. Individual varia- 

 tions were not so marked as among savage skulls, but 

 the average amounts were very similar, although in no 

 fewer than seventeen skulls the excess occurred upon 

 the right side. 



(4) Asterionic diameter. In fifteen skulls the excess was 

 on the left side, but throughout the whole series the 

 asymmetry was slight and presented very little difference 

 from the conditions in the savage skulls. 



II. BASI-BREGMATIC HEIGHT. 



On the total average height, Scandinavian dolicho-cephalic 

 skulls were 5 mm. less than dolicho-cephalic Australian 

 Aboriginals, and Scandinavian brachy-cephalic skulls were
