unfolded from the days of Galvani to those of Faraday,
and of many others which are still inscrutable to us, is exhibited in
this structure." Well may Mr. Darwin say, "It is impossible to conceive
by what steps these wondrous organs have been produced. We see the
purpose--that a special apparatus should be prepared; but we have not
the remotest notion of the means employed. Yet we can see so much as
this, that here again, other laws, belonging altogether to another
department of nature--laws of organic growth--are made subservient to a
very definite and very peculiar purpose.' [tr. note: sic on punctuation]

"The new-born kangaroo," says Professor Owen, "is an inch in length,
naked, blind, with very rudimental limbs and tail; in one which I
examined the morning after the birth, I could discern no act of sucking;
it hung, like a germ, from the end of the long nipple, and seemed unable
to draw sustenance therefrom by its own efforts. The mother accordingly
is provided with a peculiar adaptation of a muscle (_cremaster_) to the
mammary gland, by which she can inject the milk from the nipple into the
mouth of the pendulous embryo. Were the larynx of the creature like that
of the parent, the milk might, probably would, enter the windpipe and
cause suffocation: but the larynx is cone-shaped, with the opening at
the apex, which projects, as in the whaletribe, into the back aperture
of the nostrils, where it is closely embraced by the muscles of the
'soft palate.' The air-passage is thus completely separated from the
fauces (mouth), and the injected milk passes in a divided stream, on
either side the base of the larynx, into the oesophagus. These
correlated modifications of maternal and foetal structures, _designed_
with especial reference to the peculiar conditions of both mother and
off-spring, afford, as it seems to me, irrefragable evidence of
_creative forsight_. The parts of this apparatus cannot have produced
one another; one part is in the mother, another part in the young one;
without their harmony they could not be effective; but nothing except
design can operate to make them harmonious. They are intended to work
together; and we cannot resist the conviction of this intention when
the facts first come before us."

We cannot stop to pass in review the structural marvels of the human eye
and ear, of the digestive organs, and circulatory system of animals, of
adaptations of fishes to the watery element. But we must ment
