24 A CRANIOMETRIC STUDY 



The Bregma-Lamhda Chord measured 109.5 mm., which 

 was likewise below the European average of 112 mm., given 

 by Buehner.(^') The maximum distance of the parietal 

 cranial arc from the chord was at a point 52.5 mm., from the 

 bregma and measured 26 mm., which was slightly above the 

 European average (" ) of 24 mm. The post-parietal and supra- 

 occipital areas of the cranial curvature were rather flattened 

 as exhibited in Figs. 7 and 12. 



The lamhda-Inion Chord was found to be 62 mm., which was 

 just below the European average of 63 mm., as given by 

 Buchner.C^') The maximum distance of the lambda-inion 

 cranial arc from the chord was at about its centre and mea- 

 sured 10.5 mm., which was practically the same as the 

 European average of 11 mm.(^') 



The Inter-Malar Breadth. — This amounted to 119 mm., 

 and was therefore less than the interzygomatic breadth. This 

 dimension proved to be practically the same as the average 

 intermalar breadth in Turner's (®) extensive series of Scottish 

 skulls. 



The Antero-Posterior Diameter of the Foramen magnum was 

 36 mm. This was practically the same as the average for 

 7 male Munsee North American Indian Crania which was 

 found by Hrdlicka (^^ to be 35 mm., and likewise appro- 

 ximated to the average dimensions of this opening in a series 

 of Scottish skulls, (') which when calculated from Turner's 

 tables proved to be 35.3 mm. The relative size of the Fora- 

 men Magnum in various races does not appear to yield any 

 definite factor of anthropological significance. 



The Palato-M axillary Index. — The palato-maxillary breadth 

 was 64.5 mm. and the length 57.5 mm., so that the palato- 

 maxillary index proved to be 112.1, thus classing the skull as 

 mesuranic. This result may be compared to 115.4 which was 

 obtained in a Melanesian skull, O thus placing it in the brach- 

 yuranic class. This index does not appear to possess any inter-
