OF THE MICMAC SKULL— CAMERON. 9 



proved to be 805 cu. cm. The total cranial capacity was thu.s 

 estimated to be approximately 1495 cu. cm. This was slightly 

 above the average for 73 male Scottish skulls, estimated by 

 Turner to be 1478 cu. cm. Still it should be mentioned that 33 

 of these had a capacity of over 1500 cu. cm. 



The Cranial Length. — The most posterior point of the skull 

 as shown in Fig. 7 was found to be about midwa}' between the 

 lambda and the inion. The measurement from the glabella 

 to this proved to be 182.5 mm. The distance from the gla- 

 bella to the inion was 9 mm. less, namely 173.5 mm. These 

 measurements were less than the mean of 117 male Scottish 

 skulls which was found by Turner (®) to be 186.6 mm. Con- 

 trast this, further, with the mean glabella-inion length of 100 

 aboriginal Australian skulls, which was found by Berry and 

 Robertson ( "^ to be 179.5 mm., (unsexed) and the mean gla- 

 bella-inion length of 44 aboriginal Tasmanian skulls (^) which 

 was found by the same two observers to be 173.1 mm. It is 

 also significant to contrast this cranial length with 190 and 

 199 m m. which were the measurements found by the author 

 in two markedly dolichocephalic New Hebiidean skulls. 



The Maximum Cranial Breadth. — This measurement proved 

 to be 147.5 mm., v/hich was just below the average for 114 

 mab Scottish skulls(*), but was much greater than the mean 

 maximum breath of 100 Australian skulls which was 130.7 

 mm., (unsexed) according to Berry and Robertson, ('") and 

 also much greater than the maximum breath of two Melane- 

 sian skulls recently recorded by the writer ('-• — 122 and 128 

 mm. 



The Cephalic Index. — This was calculated to be 80.8, a 

 result which practicalh' accorded with the figure estimated by 

 Mr. H. Piers, the Curator of the Nova Scotia Provincial 

 Museum, and noted by him on the descriptive label attached 

 to the skull. The cranium was thus definitely brachycephalic,
