The English skull closely resembles the Bavarian in variability of length and 
breadth, but there is a marked difference between the two as regards auricular 
height. 
There are few data for comparison of the coefficients of variation of the 
circumferential measurements :

Here again we observe that English and Bavarian males are equally variable, 
and that the Eaglish female, unlike the Naqada, is more variable than the male in 
both circumferences. Relatively to the horizontal circumfei'ences the greater 
variability in the vertical circumference is in our series very marked. 
Comparing length of palate, we have the following coefficients of variation :

The English and Bavarian diff'er considerably, but in all three races the female 
is the more variable.
