If the Sperm Whale be physiognomically a Sphinx, to the phrenologist his brain seems that geometrical circle which it is impossible to square.

In the full-grown creature the skull will measure at least twenty feet in length. Unhinge the lower jaw, and the side view of this skull is as the side view of a moderately inclined plane resting throughout on a level base. But in life--as we have elsewhere seen--this inclined plane is angularly filled up, and almost squared by the enormous superincumbent mass of the junk and sperm. At the high end the skull forms a crater to bed that part of the mass; while under the long floor of this crater--in another cavity seldom exceeding ten inches in length and as many in depth reposes the mere handful of this monster's brain. The brain is at least twenty feet from his apparent forehead in life; it is hidden away behind its vast outworks, like the innermost citadel within the amplified fortifications of Quebec. 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. As for his true brain, you can then see no indications of it, nor feel any. The whale, like all things that are mighty, wears a false brow to the common world.

If you unload his skull of its spermy heaps and then take a rear view of its rear end, which is the high end, you will be struck by its resemblance to the human skull, beheld in the same situation, and from the same point of view. Indeed, place this reversed skull (scaled down to the human magnitude) among a plate of men's skulls, and you would involuntarily confound it with them; and remarking the depressions on one part of its summit, in phrenological phrase you would say--This man had no self-esteem, and no veneration. And by those negations, considered along with the affirmative fact of his prodigious bulk and power, you can best form to yourself the truest, though not the most exhilarating conception of what the most exalted potency is.

But if from the comparative dimensions of the whale's proper brain, you deem it incapable of being adequately charted, then I have another ............
