Breadth of Head 



The greatest breadth of the head gives the moderate mean of 14.4 

 cm. It varies to the extent of 25 mm., or 0.088 per each cm. of the 

 average, hence slightly more than the length ; the curve of distribu- 

 tion, however (fig. 4), though quite shouldered, is unusually solid. 



KHARGA OASIS, MEN: DIAMETER LATERAL MAXIMUM OF HEAD 



Number of individuals measured: 150. 



Average: 14.14cm. 1 (1st 50: 14.14; 2d 50: 14.06; 3d 50: 14.22cm.) 



Median : 14.2 cm. Mode : 14.4 cm. 



Minimum : 12.8 cm. Maximum : 15.3 cm.

Both the length and the breadth of the head augment, as will be 

 seen in the next table, with the height of the body, and they augment 

 at nearly the same ratio. The latter fact indicates that it is in
