Сторінка 169 - Earthworms, though in appearance a small and despicable link in the chain of Nature, yet, if lost, would make a lamentable chasm.
Сторінка 60 - On my return home, it occurred to me, in 1837, that something might perhaps be made out on this question by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it. After five years...
Сторінка 53 - Seeing every height crowned with its crater, and the boundaries of most of the lava-streams still distinct, we are led to believe that within a period, geologically recent, the unbroken ocean was here spread out. Hence, both in space and time, we seem to be brought somewhat near to that great fact — that mystery of mysteries — the first appearance of new beings on this earth.
Сторінка 62 - The English intelligence in particular shows itself as a rule congenitally incapable of appreciating the superior logical certitude of the deductive method.

Сторінка 53 - The natural history of these islands is eminently curious, and well deserves attention. Most of the organic productions are aboriginal creations, found nowhere else; there is even a difference between the inhabitants of the different islands; yet all show a marked relationship with those of America, though separated from that continent by an open space of ocean, between 500 and 600 miles in width.
Сторінка 44 - Delight itself, however, is a weak term to express the feelings of a naturalist who, for the first time, has wandered by himself in a Brazilian forest. The elegance of the grasses, the novelty of the parasitical plants, the beauty of the flowers, the glossy green of the foliage, but above all the genoral luxuriance of the vegetation, filled me with admiration.
