analysing the weights of 2100 adult male and 

 1034 adult female brains of Swedes, Bavarians, 

 Hessians, Bohemians, and English, reported in 

 the Journal of the Biometrical Society : " There is no 

 evidence that brain weight is sensibly correlated 

 with intellectual ability. Of the five races in- 

 vestigated by the biometricians, the English have 

 the smallest mean brain weight. The mean of 

 the adult Englishmen is 27 grams less than the 

 Bavarian mean, G^ grams less than the Swedish 

 mean, and 120 grams less than the Bohemian 

 mean."
