BRAIN-FORCING IN CHILDHOOD. 731 



small superficies. Still, these are exceptional cases ; as a rule, the 

 larger the brain the greater the mental power of the individual. 



Another difference between the brain of man and that of woman is 

 found in the conformation of the organ. In man the frontal region is 

 more developed than it is in woman. There is a certain fissure called 

 the fissure of Rolando, which divides the brain into two unequal parts. 

 Now, if we take the entire length of the brain as = 100, there will be 

 found in woman 31 3 parts in front of the upper end of this fissure, 

 while in man there will be 43*9 parts. 



Again the specific gravity of the male brain, both of the white and 

 the gray substance, is greater in man than it is in woman. 



Bearing in view these differences, it is impossible to avoid the con- 

 clusion that there must also be some points of dissimilarity in the 

 minds of the two sexes. Not necessarily that one is superior to the 

 other, but that they are different. This is an assertion that will prob- 

 ably not be questioned by any one who will take the trouble to give a 

 little reflection to the matter. We see the diversities every day — di- 

 versities of perception, of emotion, of intellect, of will. In some re- 

 spects the mind of man excels ; in others, that of woman is superior. 

 It would be a bad state of things for mankind if the mind in the two 

 primary divisions of the human race were the same. In barbarous 

 nations, as we have seen, the difference in size is less than it is with 

 civilized people, and as one consequence of this fact there is not so 

 great a difference in the mental development. The Avork of a woman 

 is with them almost the same as that of a man. Her mode of life, her 

 dress are not essentially different except in so far as they must be dif- 

 ferent on account of her sex. But with civilized nations there is vari- 

 ety in modes of thought, in likes and dislikes, and in other mental 

 characteristics ; in occupation, in manner, in clothes, even in food, so 

 that the differentiation between the sexes is far more distinctly marked 

 than it is with nations low in the scale of progress. Who can doubt 

 that this is the direct result of differences not only in the brain but in 

 other parts of the nervous system ? 



It appears to me, therefore, that while the education of a woman 

 should be just as thorough as that of a man, it ought not to be the 

 same. The two sexes move through paths that approach parallelism 

 at some points of their course ; but they can never travel exactly the 

 same road till they have nervous systems presenting exactly the same 

 anatomical configuration and situation.* 



Such being the case, it is the height of absurdity to attempt, what 

 is so often attempted at the present day, the education of girls accord- 

 ing to the same method as that pursued for boys, and giving them 



* The immediately preceding paragraphs on the differences between the brains of man 

 and woman are taken almost verbatim from my address entitled " The Relations between 

 the Mind and the Nervous System," delivered at the Lehigh University on " Founder's Day," 

 October 9, 1884, and published in "The Popular Science Monthly" for November, 1884.
