Ere quitting, for the nonce, the Sperm Whale's head, I would have you, as a sensible physiologist, simply--particularly remark its front aspect, in all its compacted collectedness. I would have you investigate it now with the sole view of forming to yourself some unexaggerated, intelligent estimate of whatever battering-ram power may be lodged there. Here is a vital point; for you must either satisfactorily settle this matter with yourself, or for ever remain an infidel as to one of the most appalling, but not the less true events, perhaps anywhere to be found in all recorded history.

You observe that in the ordinary swimming position of the Sperm Whale, the front of his head presents an almost wholly vertical plane to the water; you observe that the lower part of that front slopes considerably backwards, so as to furnish more of a retreat for the long socket which receives the boom-like lower jaw; you observe that the mouth is entirely under the head, much in the same way, indeed, as though your own mouth were entirely under your chin. Moreover you observe that the whale has no external nose; and that what nose he has--his spout hole-- is on the top of his head; you observe that his eyes and ears are at the sides of his head; nearly one third of his entire length from the front. Wherefore, you must now have perceived that the front of the Sperm Whale's head is a dead, blind wall, without a single organ or tender prominence of any sort whatsoever. Furthermore, you are now to consider that only in the extreme, lower, backward sloping part of the front of the head, is there the slightest vestige of bone; and not till you get near twenty feet from the forehead do you come to the full cranial development. So that this whole enormous boneless mass is as one wad. Finally, though, as will soon be revealed, its contents partly comprise the most delicate oil; yet, you are now to be apprised of the nature of the substance which so impregnably invests all that apparent effeminacy. In some previous place I have described to you how the blubber wraps the body of the whale, as the rind wraps an orange. Just so with the head; but with this difference: about the head this envelope, though not so thick is of a boneless toughness, inestimable by any man who has not handled it. The severest pointed harpoon, the sharpest lance darted by the strongest human arm, impotently rebounds from it. It is as though the forehead of the Sperm Whale were paved with horses' hoofs. I do not think that any sensation l............
