Ability with the Size and of the Head.

honours men. But to any one acquainted with the present Cambridge system the division thus made will appear a well-marked and distinctive one. I think the majority of college tutors would undoubtedly agree in the broad statement, that the poll man cannot be compared for intellectual ability with the honours man. Making this broad division, we are at once able to use the method cf my paper : " On the Correla- tion of Characters not Quantitatively Measurable."*

The characters dealt with from the Cambridge measurements were

(a) Cephalic Index ; (/>) Length of Head ; (<) Breadth of Head. The classifications adopted were : for (<i) indices under and over eighty ; for

(b) lengths under and over 7*65 inches; and for (r) breadth under and over 6 '05 inches.

The following fourfold tables resulted from the classification :

(a.) Cephalic Index.

The correlation therefore between ability and dolichocephaly is r = 0-0305 0-0349.
