Spitzka (iqo^b) collected a large number of brain weights of 

 scholars which prove that mentality is indicated by weight if we 

 neglect other factors. The objections stated above may be applied 

 equally well here, for. if by the arrangement below we eliminate 

 the ethnological factor (if such exist), we have not disposed of 

 the others, since the number is too small to render them negligible.

A\'endt (1909) made a careful study of the relation of body- 

 weight and height to brain weight from infancy to old age for 

 both sexes. He concludes that the ma'r brain is actually heavier 

 than the female, and that weight and intelligence are directly 

 related Nicolucci (1881) attributes the difference in weight 

 between the sexes not to the height and body-weight variations 

 but to the general organization of the sexes. Pearl (1905) has 

 made a careful analysis of statistics and concludes that they all 

 agree in showing that the male brain is absolutely heavier than 

 the female brain irrespective of other factors. 



Topinard (1885) showed, from available figures, that the 

 shape of the brain introduced another factor ; while the brachio- 

 cephalic brain was heavier in the male, in the female the dolico- 

 cephalic brain had the advantage. He recognized, however, that 

 sut^cient figures were not available to make the conclusion a 

 positive fact. 



^ The word " American " is used for lack of a better word to describe 

 those Caucasians living in the United States. I fully appreciate the fact 

 that we can not consider them as a race in ethnological studies, for, since 

 they represent in themselves possiblj- a number of races, we should have 

 in any considerable number an absence of strong race differentiating fea- 

 tures. I feel that they may be included in this table, since the only object 

 is to arrive at an approximate average weight for scholars regardless of race.
