400 PRINCIPAL SIR W. TURNER ON 



The mean length of the base-line was 134'5 mm., that of the total longitudinal arc 

 359 mm., and that of the total longitudinal circumference 495 mm. The range in the 

 proportion of base-line to the longitudinal arc varied in the Tasmanian skulls from 

 2 5 to 2 "9, with the mean 2 "63 ; whilst the proportion to the longitudinal circumference 

 ranged from 3 '5 to 4, with the mean 3 "6 5. The skull No. 5 was that which possessed 

 the greatest proportion of base-line both to the longitudinal arc and to the circumference. 



I have elsewhere shown that the mean base-line in seventeen Scottish skulls was to 

 the arc as 1 to 2 '8, and in twenty male Australians as 1 to 2 "7. The larger the pro- 

 portion of arc to base-line the greater is the curvature of the vault of the skull for the 

 lodgment of the cerebrum.
