But men of science are by no means at one on this alleged sexual difference in brain convolutions. On the contrary, there are many eminent physiologists and anatomists who contend that the superficies of brain convolutions in women is relatively greater than in men. For those who believe--and they are probably the majority at present--that the seat of mental activity is in the gray matter of the brain, this greater brain surface, due to its convolutions, would be a decided compensation for woman's relatively smaller brain volume.[98] In whatever way, then, we consider the brains of men and women, whether we compare the ratio of brain weight to height of body or to weight of body, or compare the relative amounts of gray matter in the two sexes, the advantage, in spite of her smaller body, is distinctly in favor of woman. From the preceding considerations it seems clear that there is no ground from the point of view of brain anatomy for considering one sex as superior to the other. They evince, too, that quality as well as quantity of brain tissue must be considered in all our discussions on the relations between the volume of brain and the intelligence of its possessor. Whales and elephants have much larger brains than men, but they nevertheless stand far below him in intelligence. It must be remembered, also, that the brain is not only an organ of mental function. It is likewise the center of the entire nervous system, and its volume, therefore, must correspond with the size and number of nerve trunks under its control. In man, as in animals, the brain elements are to a great extent but sensori-motor delegates whose function is the regulation and government of every part of the body. The superior size of the whale's brain, as compared with that of man, can readily be understood when we reflect on the much greater amount of territory which these sensori-motor delegates represent. When this fact is borne in mind it will be found that the whale's brain, relatively to that of man, is extremely small. For while the ratio of man's brain weight to that of his body is as 1 to 36, the ratio of the whale's brain weight to its immense body is but 1 to 3,000. As an evidence that quality often counts for more than quantity, brain anatomists would do well to reflect on the marvelous intelligence displayed by ants and termites, those mites of animated nature which so excited the admiration of the naturalist Pliny and caused Darwin to declare, "The brain of an ant is one of the most marvelous atoms of matter in the world, perhaps more so than the brain of man."[99]
