That there is a close likeness between all these bodies is obvious from the fact that when any of them is strongly heated, or allowed to putrefy, it gives off the same sort of disagreeable smell; and careful chemical analysis has shown that they are, in fact, all composed of the elements carbon, hydrogen, oxygen, and nitrogen, combined in very nearly the same proportions. Indeed, charcoal, which is impure carbon, might be obtained by strongly heating either a handful of corn, or a piece of fowl's flesh, in a vessel from which the air is excluded so as to keep the corn or the flesh from burning. And if the vessel were a still, so that the products of this destructive distillation, as it is called, could be condensed and collected, we should find water and ammonia, in some shape or other, in the receiver. Now ammonia is a compound of the elementary bodies, nitrogen and hydrogen; therefore both nitrogen and hydrogen must have been contained in the bodies from which it is derived.
Among the various wild animals which inhabit the earth, it is difficult to decide which are really friendly and which are really hostile to man's interests. The actual fact appears to be that there is neither hostility nor friendship. If farmers and gardeners kill off too many birds, nature revenges herself by sending a plague of insects which the small birds, if alive, would have eaten. Gamekeepers ruthlessly shoot hawks and kites, or snare stoats and polecats, with the result that their game grows up too thick for its feeding ground, sickly specimens are allowed to linger on, and a destructive murrain follows. The rook, no doubt, is fond of eggs; but nevertheless he does the farmer good service when he devours the grubs which are turned up by the plow; and as the salmon disease, which of late has proved so destructive, is attributed by the best authorities to overcrowding, that glossy-coated fisherman, the otter, is really a benefactor to the followers of Izaak Walton's gentle craft.
