A CONTRIBUTION TO THE STUDY OF THE SCOTTISH SKULL.

24. The angle of parietal curvature. 



25. The parietal frontal arc index, i.e. 



parietal arc x 100 



frontal arc 



26. The lambda angle. 



27. The opisthionic angle. 



Berry in his researches on the Tasmanian and Australian skulls takes male and 

 female results together as unsexed skulls, and as the Scottish series under investiga- 

 tion consists of male skulls only, I have calculated the mean values for the above 

 observations in the male Tasmanian and Australian skulls in Berry's series so that 

 the results may be truly comparable. The mean values obtained for the absolute 

 measurements of the male skull are slightly greater than those for the unsexed skull, 

 as one would expect, whereas the values for the indices are little if at all altered. 



The mean values for the observations may be arranged in the form of a table to 

 compare them with the Tasmanian and Australian, as is shown in Table LI. In this 

 Berry's results for the unsexed skulls are placed alongside the corresponding male 

 values, and the close correspondence on the whole between the two sets of values 

 will be very apparent.
