Стр. 88 - There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.
Стр. 61 - as the white man's rat has driven away the native rat, so the European fly drives away our own ; and as the clover kills our fern, so will the Maori disappear before the white man himself.
Стр. 49 - A second great fact which strikes us in our general review is, that barriers of any kind, or obstacles to free migration, are related in a close and important manner to the differences between the productions of various regions.

Стр. 41 - Now, is it a worthy conception of Deity that, while neglecting to maintain his unity of ideal in the case of nearly all the numerous species of snakes, he should have added a tiny rudiment in the case of the Python— and even in that case should have maintained his ideal very inefficiently, inasmuch as only two limbs, instead of four, are represented...
Стр. 69 - which forms the fulcrum when standing or walking, is perhaps the most characteristic peculiarity, in the human structure ;" but in an embryo, about an inch in length. Prof. Wyman found "that the great toe was shorter than the others ; and, instead of being parallel to them, projected at an angle from the side of the foot, thus corresponding with the permanent condition of this part in the quadrumana.
Стр. 38 - ... great departure from the typical form — such as the absence of limbs — without some of the other organs in the body being so far modified as of themselves to indicate, on the supposition of descent with modification, that the animal or plant must have been subject to the modifying influences for a long series of generations. And this combined testimony of a number of organs in the same organism is what the theory of descent would lead us to expect, while the rival theory of design can offer...
Стр. 88 - When I view all beings not as special creations but as the lineal descendants of some few beings which lived long before the first bed of the Silurian system was deposited, they seem to me to become ennobled.
Стр. 67 - I25th of an inch in diameter, which differs in no respect from the ovules of other animals. The embryo itself at a very early period can hardly be distinguished from that of other members of the vertebrate kingdom. At this period the arteries run in arch-like branches, as if to carry the blood to branchiae which are not present in the higher vertcbrata, though the slits on the sides of the neck still remain, marking their former position.
