nimal, if
reasonably dense, what can that be but the skin? True, from the unmarred
dead body of the whale, you may scrape off with your hand an infinitely
thin, transparent substance, somewhat resembling the thinnest shreds
of isinglass, only it is almost as flexible and soft as satin; that is,
previous to being dried, when it not only contracts and thickens, but
becomes rather hard and brittle. I have several such dried bits, which
I use for marks in my whale-books. It is transparent, as I said before;
and being laid upon the printed page, I have sometimes pleased myself
with fancying it exerted a magnifying influence. At any rate, it is
pleasant to read about whales through their own spectacles, as you may
say. But what I am driving at here is this. That same infinitely thin,
isinglass substance, which, I admit, invests the entire body of the
whale, is not so much to be regarded as the skin of the creature, as
the skin of the skin, so to speak; for it were simply ridiculous to say,
that the proper skin of the tremendous whale is thinner and more tender
than the skin of a new-born child. But no more of this.

Assuming the blubber to be the skin of the whale; then, when this skin,
as in the case of a very large Sperm Whale, will yield the bulk of one
hundred barrels of oil; and, when it is considered that, in quantity, or
rather weight, that oil, in its expressed state, is only three fourths,
and not the entire substance of the coat; some idea may hence be had
of the enormousness of that animated mass, a mere part of whose mere
integument yields such a lake of liquid as that. Reckoning ten barrels
to the ton, you have ten tons for the net weight of only three quarters
of the stuff of the whale's skin.

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 i
