The fact is indisputable that, taking the average, say, of a hundred brains, the man has five or six ounces more brain than the woman. Some women will, of course, be found to have much larger brains than some men; but whenever the comparison embraces a sufficient number to yield a fair average, the superiority is invariably on the side of the man. And it is worthy of special remark that it is in the cerebrum, or brain proper, that these differences are very trifling.
Now, when we reflect that the cerebrum is generally supposed to be the exclusive organ of the intelectual, volitional, and emotive faculties, and that it forms about nine-tenths of the whole mass usually designated as "the brain", or more correctly as "the encephalon", this marked superiority in the male cerebrum seems to lend scientific authority to the general verdict regarding the
intellectual inferiority of women.
