Brain

True, both his eyes, in themselves, must simultaneously act; but is his brain so much more comprehensive, combining, and subtle than man’s, that he can at the same moment of time attentively examine two distinct prospects, one on one side of him, and the other in an exactly opposite direction? If he can, then is it as marvellous a thing in him, as if a man were able simultaneously to go through the demonstrations of two distinct problems in Euclid. Nor, strictly investigated, is there any incongruity in this comparison.

So like a choice casket is it secreted in him, that I have known some whalemen who peremptorily deny that the Sperm Whale has any other brain than that palpable semblance of one formed by the cubic-yards of his sperm magazine. Lying in strange folds, courses, and convolutions, to their apprehensions, it seems more in keeping with the idea of his general might to regard that mystic part of him as the seat of his intelligence.

It is plain, then, that phrenologically the head of this Leviathan, in the creature’s living intact state, is an entire delusion.

And what is still more, for many feet after emerging from the brain’s cavity, the spinal cord remains of an undecreasing girth, almost equal to that of the brain. Under all these circumstances, would it be unreasonable to survey and map out the whale’s spine phrenologically? For, viewed in this light, the wonderful comparative smallness of his brain proper is more than compensated by the wonderful comparative magnitude of his spinal cord.
