out, while "in the average Enghshman the brain 

 weighs 1,360 grammes; in Cromwell it is said to have 

 been 2,231 grammes and in Byron 2,238 grammes. 

 In Gambetta, the French statesman, it weighed only 

 1,294 grammes. "20 



"The brain-weight of the various races," Marion J. 

 Mayo sets forth, "has been subjected to numerous 

 measurements, with the result that important racial 

 differences seem to appear. A relatively small brain- 

 weight is found to be characteristic of the negroid 

 races, and a relatively great weight of the white race, 

 even when all other facts are taken into consideration. 

 Now it has been found that while no certain cor- 

 relation can be affirmed between the size of the brain 

 and the degree of intelligence in individual cases, yet 

 when large groups are considered some significance 



does seem to attach to the matter of size From 



a study of the brains of 103 negroes and 49 American 

 whites, Robert Bennett Bean reached the following 

 conclusion: 'The brain-weight of the Negro is 

 demonstrably smaller than that of the Caucasian.' "^^ 



Another writer says: "The average brain-weight 

 is: 



Of Europeans, 49 ounces, or 1,390 grammes; 



Of Negroes, 44 ounces, or 1,250 grammes.'
