1905.] SCANDINAVIAN CRANIA. 13 



whereas the supra-zygomatic percentage is distinctly less than 

 the corresponding figure for the dolicho- and brachy-cephalic 

 skulls, yet the infra-zygomatic percentage is greater than that 

 for these tvvo classes of skulls. 



Considered as a wjiole, the facts obtained from the study 

 of the basi-bregmatic diameter do not place the mesati-cephalic 

 crania in an intermediate position between dolicho-cephalic and 

 brachy-cephalic crania. A consideration of the averages of the 

 total height of this diameter show the mesati-cephalic skulls 

 below the other two groups, while an examination of its pro- 

 portions retains the mesati-cephals in the same position as 

 regards the supra-zygomatic segment, but places them above the 

 other two groups as regards the infra-zygomatic segment. 



If we take all three groups of Scandinavian crania, and 

 compare the figures derived from them with those formerly 

 recorded in connection with the dolicho-cephalic skulls of Austra- 

 lian Aboriginals and brachy-cephalic Sandwich Islanders in 

 relation to the basi-bregmatic height either considered as a whole 

 or in its supra- and infra-zygomatic segments, we find that the 

 brachy-cephalic skulls are constructed on proportions which 

 closely correspond. This is shown by the percentages which 

 are referable to the supra- and infra-zygomatic segments respec- 

 tively, although the average total amounts are distinctly smaller 

 among the Scandinavian than among the Sandwich Island skulls. 

 Probably the small increase in the percentage proportion of the 

 supra-zygomatic segment of the Scandinavian skulls might have 

 been improved upon if a larger number of skulls had been 

 available for examination. This is all the more probable when 

 we find that the percentage proportions of the Scandinavian 

 mesati-cephalic skulls are distinctly belter than the corresponding 

 figures derived from Australian dolicho-cephalic skulls, notwith- 

 standing that the average total height of the former was much 

 less than that of the latter. 



The most striking contrast however is to be found between 

 the Scandinavian and Australian dolicho-cephalic skulls. In the 

 former the average basi-bregmatic diameter is distinctly less
