1905.] SCANDINAVIAN CRANIA. 17 



(2) The post-condyloid segment varied from 87 to 104 mm. 

 giving an average length of 93.9 mm. or an average of 

 50.29 per cent. of the total length. 



Compared wfth the Australian Aboriginals, these are very 

 remarkable figures; for in the Australian skulls the average 

 lengths of the præ- and post-condyloid segments were 99.9 and 

 87.5 mm. respectively, and their average percentages of the total 

 length were 53.2 and 46.6. From this comparison it is perfectly 

 clear that in its balance or poise upon the summit of the spinal 

 column, a Scandinavian dolicho-cephalic skull differs very mate- 

 rially from that of an Aboriginal Australian. Although both of 

 the skulls are dolicho-cephalic in their length-breadth proportions, 

 yet in the Scandinavian the position of the occipital condyle is 

 nearly 4 per cent. of the total length farther forwards, i. e. in 

 the frontal direction. 



(b) Brachy-cephalic. 



(1) The præ-condyloid segment varied from 84 to 95 mm., 

 giving an average length of 89.8 mm. or an average of 

 49.2 per cent of the total length. 



(2) The post-condyloid segment varied from 88 to 96 mm., 

 giving an average of 92.5 mm. or an average of 50.7 

 per cent. of the total length. 



Again, in comparison with the skulls of brachy-cephalic 

 Sandwich Islanders we find a similar change in these propor- 

 tions in favour of the Scandinavian skulls. The Sandwich 

 Island skulls gave an average length of 92.5 mm. to the præ- 

 condyloid segment, yielding 52.7 per cent. of the total length, 

 and 82.7 mm. as an average post-condyloid segment, the per- 

 centage of length being 47.1. 



Thus the Scandinavian skull has had its præ-condyloid seg- 

 ment reduced by 3.5 per cent., and its post-condyloid segment 

 increased by 3.6 per cent. 



(c) Mesati-cephalic. 



(1) The præ-condyloid segment varied from 85 to 95 mm., 

 giving an average of 91 mm. or an average of 51.1 per 

 cent. of the total length.
