SECTION VI. DATA FOR COMPARISON. 



Source of the Material. 



I have collected material from many different sources. In 

 1897, K - Pearson I gave the coeff. of variation for 1000 English 

 middleclass men, 390 Bavarian men. 284 French (from statistics 

 given in "Memoires de la Societe d* Anthropologic de Paris," 1888) 

 and also some data for American school children (from the years 

 6 to io, taken from Porter's u Growth of Saint Louis Children "). 

 I have retained his French and German data but have substituted 

 corrected values for Englishmen given by Pearson in a later 

 paper. I have omitted the children as being all under the ao e 

 10. 



Pearson also reduced statistics for U.S.A. recruits 4 and gave 

 final figures for his family data 3 in Biometrika in 1903. & His 

 family 'lata consists of [078 records of middle class English fathers 

 and sons. 



Powys*gaye the heights of 2862 male criminals from New- 

 South Wales, distributed into different age-groups. I have select- 

 ed the total variability 5 of the whole group, for in our Anglo- 

 Indian data men of all ages are present. Powys considers & his 

 data to be il extremely homogeneous.' '* 



In 1901, W. R. MacdonelP discussed the measurements for 

 3000 English criminals. He also calculated the coeff. of variation 

 for 1000 Cambridge undergraduates. 8 



Raymond Pearl 9 has calculated variabilities of stature for 

 416 Swedes, 475 Hessians, 266 Bohemians, and 365 Bavarians. 10 

 The measurements were all taken on dead bodies and the coeff. of 

 variation are 4'0o<)±-094, 3-954*' "7, 4'323± # i27 and |'838±*oo6 

 respectively. 



Blakeman 11 has analysed a short series of 117 English males 

 who died in hospitals. The coeff. of variation '■ for stature is
