Sperm Whale-Coding

In life, the visible surface of the Sperm Whale is not the least among the many marvels he presents. Almost invariably it is all over obliquely crossed and re-crossed with numberless straight marks in thick array, something like those in the finest Italian line engravings. But these marks do not seem to be impressed upon the isinglass substance above mentioned, but seem to be seen through it, as if they were engraved upon the body itself. Nor is this all. In some instances, to the quick, observant eye, those linear marks, as in a veritable engraving, but afford the ground for far other delineations. These are hieroglyphical; that is, if you call those mysterious cyphers on the walls of pyramids hieroglyphics, then that is the proper word to use in the present connexion. By my retentive memory of the hieroglyphics upon one Sperm Whale in particular, I was much struck with a plate representing the old Indian characters chiselled on the famous hieroglyphic palisades on the banks of the Upper Mississippi. Like those mystic rocks, too, the mystic-marked whale remains undecipherable.
