Trang 18 - In fact," we find him remarking, " life exercising upon the elements which at every instant form part of the living body, and upon those which it attracts to it, an action contrary to that which would be produced without it by the usual chemical affinities, it is inconsistent to suppose that it can itself be produced by these affinities.
Trang 46 - The natural food of man," says Cuvier, "judging from his structure, appears to consist principally of the fruits, roots, and other succulent parts of vegetables.
Trang 398 - On carefully examining between the blades of grass in the fields above described, the author found that there was scarcely a space of two inches square without a little heap of the cylindrical castings of worms.

The Armenian or Syrian branch, stretching to the south, produced the Assyrians, the Chaldeans, the hitherto...

Now, this art of method, when once well acquired, may be applied with infinite advantage to studies the most foreign to natural history. Every discussion which supposes a classification of facts, every research which requires a distribution of matters, is performed after the same manner...

Trang 49 - Chinese, confined exclusively to their own empire, furnishes little that is satisfactory with respect to their neighbours. The affinities of their languages are also too little known to direct us in this labyrinth. The languages of the north of the peninsula beyond the Ganges, as well as that of Thibet, bear some...
