CHAPTER 103
Measurement of The Whale's Skeleton
In the first place, I wish to lay before you a particular, plain
statement, touching the living bulk of this leviathan, whose
skeleton we are briefly to exhibit. Such a statement may prove
useful here.
According to a careful calculation I have made, and which I partly
base upon Captain Scoresby's estimate, of seventy tons for the largest
sized Greenland whale of sixty feet in length; according to my careful
calculation, I say, a Sperm Whale of the largest magnitude, between
eighty-five and ninety feet in length, and something less than forty
feet in its fullest circumference, such a whale will weigh at least
ninety tons; so that, reckoning thirteen men to a ton, he would
considerably outweigh the combined population of a whole village of
one thousand one hundred inhabitants.
Think you not then that brains, like yoked cattle, should be put
to this leviathan, to make him at all budge to any landsman's
imagination?
Having already in various ways put before you his skull, spout-hole,
jaw, teeth, tail, forehead, fins, and divers other parts, I shall
now simply point out what is most interesting in the general bulk of
his unobstructed bones. But as the colossal skull embraces so very
large a proportion of the entire extent of the skeleton; as it is by
far the most complicated part; and as nothing is to be repeated
concerning it in this chapter, you must not fail to carry it in your
mind, or under your arm, as we proceed, otherwise you will not gain
a complete notion of the general structure we are about to view.
In length, the Sperm Whale's skeleton at Tranque measured
seventy-two feet: so that when fully invested and extended in life, he
must have been ninety feet long; for in the whale, the skeleton
loses about one fifth in length compared with the living body. Of this
seventy-two feet, his skull and jaw comprised some twenty feet,
leaving some fifty feet of plain backbone. Attached to this back-bone,
for something less than a third of its length, was the mighty circular
basket of ribs which once enclosed his vitals.
To me this vast ivory-ribbed chest, with the long, unrelieved spine,
extending far away from it in a straight line, not a little
resembled the hull of a great ship new-laid upon the stocks, when only
some twenty of her naked bow-ribs are inserted, and the keel is
otherwise, for the time, but a long, disconnected timber.
The ribs were ten on a side. The first, to begin from the neck,
was nearly six feet long; the second, third, and fourth were each
successively longer, till you came to the climax of the fifth, or
one of the middle ribs, which measured eight feet and some inches.
From that part, the remaining ribs diminished, till the tenth and last
only spanned five feet and some inches. In general thickness, they all
bore a seemly correspondence to their length. The middle ribs were the
most arched. In some of the Arsacides they are used for beams
whereon to lay footpath bridges over small streams.
In considering these ribs, I could not but be struck anew with the
circumstance, so variously repeated in this book, that the skeleton of
the whale is by no means the mould of his invested form. The largest
of the Tranque ribs, one of the middle ones, occupied that part of the
fish which, in life, is greatest in depth. Now, the greatest depth
of the invested body of this particular whale must have been at
least sixteen feet; whereas, the corresponding rib measured but little
more than eight feet. So that this rib only conveyed half of the
true notion of the living magnitude of that part. Besides, for some
way, where I now saw but a naked spine, all that had been once wrapped
round with tons of added bulk in flesh, muscle, blood, and bowels.
Still more, for the ample fins, I here saw but a few disordered
joints; and in place of the weighty and majestic, but boneless flukes,
an utter blank!
How vain and foolish, then, thought I, for timid untravelled man
to try to comprehend aright this wondrous whale, by merely pouring
over his dead attenuated skeleton, stretched in this peaceful wood.
No. Only in the heart of quickest perils; only when within the
eddyings of his angry flukes; only on the profound unbounded sea,
can the fully invested whale be truly and livingly found out.
But the spine. For that, the best way we can consider it is, with
a crane, to pile its bones high up on end. No speedy enterprise. But
now it's done, it looks much like Pompey's Pillar.
There are forty and odd vertebrae in all, which in the skeleton
are not locked together. They mostly lie like the great knobbed blocks
on a Gothic spire, forming solid courses of heavy masonry. The
largest, a middle one, is in width something less than three feet, and
in depth more than four. The smallest, where the spine tapers away
into the tail, is only two inches in width, and looks something like a
white billiard-ball. I was told that there were still smaller ones,
but they had been lost by some little cannibal urchins, the priest's
children, who had stolen them to play marbles with. Thus we see how
that the spine of even the hugest of living things tapers off at
last into simple child's play.
