ct. This fin is some
three or four feet long, growing vertically from the hinder part of the
back, of an angular shape, and with a very sharp pointed end. Even if
not the slightest other part of the creature be visible, this isolated
fin will, at times, be seen plainly projecting from the surface. When
the sea is moderately calm, and slightly marked with spherical ripples,
and this gnomon-like fin stands up and casts shadows upon the wrinkled
surface, it may well be supposed that the watery circle surrounding it
somewhat resembles a dial, with its style and wavy hour-lines graved on
it. On that Ahaz-dial the shadow often goes back. The Fin-Back is not
gregarious. He seems a whale-hater, as some men are man-haters. Very
shy; always going solitary; unexpectedly rising to the surface in the
remotest and most sullen waters; his straight and single lofty jet
rising like a tall misanthropic spear upon a barren plain; gifted with
such wondrous power and velocity in swimming, as to defy all present
pursuit from man; this leviathan seems the banished and unconquerable
Cain of his race, bearing for his mark that style upon his back. From
having the baleen in his mouth, the Fin-Back is sometimes included with
the right whale, among a theoretic species denominated WHALEBONE WHALES,
that is, whales with baleen. Of these so called Whalebone whales, there
would seem to be several varieties, most of which, however, are little
known. Broad-nosed whales and beaked whales; pike-headed whales; bunched
whales; under-jawed whales and rostrated whales, are the fishermen's
names for a few sorts.

In connection with this appellative of "Whalebone whales," it is of
great importance to mention, that however such a nomenclature may be
convenient in facilitating allusions to some kind of whales, yet it is
in vain to attempt a clear classification of the Leviathan, founded upon
either his baleen, or hump, or fin, or teeth; notwithstanding that those
marked parts or features very obviously seem better adapted to afford
the basis for a regular system of Cetology than any other detached
bodily distinctions, which the whale, in his kinds, presents. How
then? The baleen, hump, back-fin, and teeth; these are things whose
peculiarities are indiscriminately dispersed among all sorts of whales,
without any regard to what may be the nature of their structure in other
and more essential particulars. Thus, the sperm whale and the humpbacked
whale, each has a hu
