A famous naturalist tried some time ago to attribute the ‘inferior talent’ of women to the lighter weight of the female brain! This is no fable! This man asserted that the greatness of the spirit was dependent on the size of the brain, and that women, on average, have a smaller brain than men. And quite truly it then happened that the methods of this learned professor were applied to himself. After his death, his brain was weighed, and it turned out that he had an abnormally small brain, a much smaller brain than those women whom he held to be of inferior mind because of their lighter brain weight.
