The distribution of hair colour amongst Scottish students is 

 about the same as that amongst Scottish schoolboys, and non-Scottish 

 students and British schoolboys are also similar, the medium type 

 prevailing amongst the two former groups, the fair and medium in 

 equal proportions amongst the latter two, while the percentage of 

 dark is fairly uniform in all, riz., about "four. The great preponder- 

 ance of the medium and dark types amongst male Scottish insane is 

 very striking. 



14. I have next to make a comparison of Variabilities. 



TABLE XI. 



COMPAKISON BETWEEN ABEEDEEN STUDENTS AND OTHER CLASSES. 



Standard Deviations. 



Here we find a general similarity in all the characters except in 

 Auricular Height, for which the insane are the least variable. 



15. We have now to see how our correlation coefficients compare 

 with those of other classes.
