A CONTRIBUTION TO THE STUDY OF THE SCOTTISH SKULL.

less variable as regards this index, then comes the Naquada, then the Scottish, while 

 the Australian is most variable. The Scottish male is less variable than the female 

 as in the Australian, unlike the relationship which obtains in the English series. 



The following table represents the variability of the height-breadth index in the 

 various types : —

In the male groups, as regards the height-breadth index, the Scottish series is the 

 least variable ; then follow the English and Australian, sensibly different and showing 

 equal variability, while the French and Naquada are still more variable and to an 

 equal degree. 



In the female groups the least variable is the English series, then comes the 

 French, then the Scottish, and last of all the Australian — most variable, with the 

 Naquada between it and the Scottish. 



The Scottish male is less variable, as regards the above index, than the female — 

 a relationship which also obtains in the Australian series, while the opposite relation- 

 ship holds in the English, French, and Naquada series. 



The standard deviations of the remaining indices in the different series are as 

 follows : —

The Scottish male is more variable, as regards upper facial index and also palatal 



index, than the female ; and, as so often occurred in the other characters examined, 



we find again the opposite relationship holding in the English series.
