criminal, and for a large series of New South Wales criminals for which 

 we are indebted to Powys. 47 



For races other than Anglo-American we have Pearson's 48 Bavarian 

 and French men and women and Pearl's 49 constants for Swedes, Hes- 

 sians and Bavarians. 



The means, standard deviations and coefficients of variation of 

 these various series are assembled in table 9. 



Comparison of the constants for stature of our total men and total 

 women with these various series is facilitated by the differences in 

 table 10. These are taken so that a positive sign indicates higher mean 

 or variability in the Nutrition Laboratory series. 



TABLE 10. Comparison of statistical constants for stature in Nutrition Laboratory series with 



the values for men and women in general. 



As far as average stature is concerned, our series show a superiority 

 practically throughout. Only the Oxford, Cambridge, and Harvard 

 men, Cambridge women, Pearson's filial generation measurements 

 for both men and women, and Pearson's Bavarian women are taller 

 than the subjects included in our normal series. 



Now comparison of average statures involves very great difficulties. 

 In none of these series is there a correction for the slight premaximum 

 increase or the postmaximum decrease occurring in the age period 

 ordinarily designated as adult life. This is probably a matter of negli-
