It will be observed that the value for spurious correlation has the same sign as 

 that for gross correlation and sometimes equals, sometimes exceeds, the latter in value 

 in the Scottish as in the other series. The coefficient of correlation (gross) between 



— and j- being positive in the Scottish series shows that in this, as in the English,

French, and Naquada groups, a tendency to brachycephaly is associated with a 

 tendency to hypsicephaly. 



It would appear that neither the opisthio-nasal length (Cleland's base line) nor 

 the transverse base in a series of skulls is entirely independent of the magnitude of 

 the capacity, as is generally believed. In the female series of 100 I calculated the 

 coefficients of correlation between these two base lengths and the cubage and found 

 that in the former case the value of the coefficient was '38 i "056, and in the latter 

 '26 i '061, showing that there is a tendency, in the female series at least, on the part 

 of both of these diameters to increase when the capacity increases. In the male 

 series of 100 skulls I also found that the coefficient of correlation between the basi- 

 nasal length and the maximum length of the skull was +'60 = [ = '043, so that there 

 is a distinct tendency shown for the former to increase when the latter increases.
