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.
