V. Data for the Frohlem of Evolution in Man .— VI. A First Study of the 
Correlation of the Human Shull. 
By Alice Lee, D.Sc., with some Assistance from Karl Pearson, F.B.S., 
University College, London. 
Received July 13,—Read November 15, 1900. 
NOTE. 
The substance of this paper was presented by Miss Lee as a thesis for the London D.Sc. in March, 1899. 
After its presentation Miss Lee asked me to criticise and revise it with a view to publication. Illness in the 
spring of 1899 and later pressure of other worh prevented my completing this revision until now. When 
Miss Lee started her work practically nothing had been published on the correlation of the parts of the 
skull; since then an interesting paper has appeared by Dr. Franz Boas. To this reference is made in the 
footnotes at points where there is agreement or disagreement with his conclusions. The subject is of 
such great scientific interest, and anthropologically of such importance, that I urged Miss Lee to somewhat 
enlarge her original thesis by a series of additional investigations now incorporated in this jjaper. I have 
further rearranged a good deal of her material and reworded some of her conclusions, but the reduction of 
the material and the inferences drawn from it are substantially her work. My task has been that of an 
editor, who wished to mould the author’s researches into a component jjart of a wider series dealing 
generally with the Cjuaiititative data for the problem of evolution in man. Such is the limit of my revision. 
I have passed of course nothing Avhich did not seem to me valid, and have suggested to the author some 
lacunte which coidd be filled up liy a consideration of additional data.— Karl Pearson.
