THE HUMAN SKULL 137 



letter appeared surely an unnecessarily unpleasant 

 letter from Professor Karl Pearson, another 

 great pundit of the weight and measurement 

 school of biologists, in the columns of Nature, 

 in which that Professor writes : " Two distin- 

 guished Oxford men of science have given a 

 very simple series of conditions by which crania 

 can be classed into skulls of negroid, non-negroid 

 and intermediate types. These conditions depend 

 entirely on a classification of nasal and facial in- 

 dices, and by their processes our authors are able 

 to distinguish between the negroid, non-negroid 

 and intermediate types among pre-historic Egypt- 

 ian crania." Then he goes on to state that he has 

 applied the rules to two groups of skulls : " First, 

 to a fairly long series of admittedly negro crania, 

 all males. I find that 7.3 per cent, are non-negroid, 

 39.0 per cent, are truely negroid, and 53.7 per 

 cent, are intermediate. It is clear that we only 

 need to let the negroes change their skins and that 

 a sensible percentage will be non-negroid. Secondly 

 to a fairly long series of English skulls, male and 

 female, I find of Englishmen 20 per cent, are 

 negroid, 46 per cent, non-negroid, and 34 per cent, 

 are intermediate in type. Among Englishwomen 

 II per cent, are negroid, 48 per cent, are non- 

 negroid, and 41 per cent, are of intermediate type. 

 Thus of the whole English population slightly 

 more than 50 per cent, are either pure negroid or 

 partially negroid ; while in an outwardly pure 

 negroid group, upwards of 60 per cent, are non- 

 negroid or mixed with non-negroid elements." 

 And he concludes with the ironical remark " that
