ans, the eye and the ear. Far back on the side of
the head, and low down, near the angle of either whale's jaw, if you
narrowly search, you will at last see a lashless eye, which you would
fancy to be a young colt's eye; so out of all proportion is it to the
magnitude of the head.

Now, from this peculiar sideway position of the whale's eyes, it is
plain that he can never see an object which is exactly ahead, no more
than he can one exactly astern. In a word, the position of the whale's
eyes corresponds to that of a man's ears; and you may fancy, for
yourself, how it would fare with you, did you sideways survey objects
through your ears. You would find that you could only command some
thirty degrees of vision in advance of the straight side-line of sight;
and about thirty more behind it. If your bitterest foe were walking
straight towards you, with dagger uplifted in broad day, you would not
be able to see him, any more than if he were stealing upon you from
behind. In a word, you would have two backs, so to speak; but, at the
same time, also, two fronts (side fronts): for what is it that makes the
front of a man--what, indeed, but his eyes?

Moreover, while in most other animals that I can now think of, the eyes
are so planted as imperceptibly to blend their visual power, so as to
produce one picture and not two to the brain; the peculiar position of
the whale's eyes, effectually divided as they are by many cubic feet of
solid head, which towers between them like a great mountain separating
two lakes in valleys; this, of course, must wholly separate the
impressions which each independent organ imparts. The whale, therefore,
must see one distinct picture on this side, and another distinct
picture on that side; while all between must be profound darkness and
nothingness to him. Man may, in effect, be said to look out on the world
from a sentry-box with two joined sashes for his window. But with the
whale, these two sashes are separately inserted, making two distinct
windows, but sadly impairing the view. This peculiarity of the whale's
eyes is a thing always to be borne in mind in the fishery; and to be
remembered by the reader in some subsequent scenes.

A curious and most puzzling question might be started concerning this
visual matter as touching the Leviathan. But I must be content with a
hint. So long as a man's eyes are open in the light, the act of seeing
is involuntary; that is, he cannot then help mechanically
