There are only two animals that have larger brains than man, the whale and the elephant. Yet, in proportion to his size, man's brain is larger. (19[C])Man's usually weighs about three pounds or a little more, and this is about one-fortieth of the weight of his whole body. The whale's body, on the other hand, is a thousand times heavier than its brain, while the elephant's body is about five hundred times as heavy. But a man who has a large brain is not necessarily more intelligent than one whose brain is smaller.
