The foregoing observations do not apply to the human race. Man was ordained to replenish the earth; hence the pliability and energy of his physical constitution, which enables him to endure the heat of the inter-tropics, and the cold of Lapland or Nova Zembla--to dwell in the deep valley or on the lofty mountain. When we say this, we look at man as a species; we do not apply our remarks to individuals, or, in other words, we do not assert that a Samoiede would enjoy the heat of Ceylon or Sumatra, or that the Ceylonese would endure the rigours of arctic Siberia; we only mean, that the fact of hot and cold climates being inhabited by our race, proves that the physical condition of man can accommodate itself to every extreme of natural temperature upon our globe. It is true, that as a general rule man modifies his food, his clothing, and even the nature of his habitation, according to the temperature and products of the climate. The Laplander clothes his body in warm furs, the Ceylonese in a scanty vesture of thin cotton. Yet the wild Indians of some parts of North America, and the natives of the dreary regions of Patagonia, are but loosely defended from the severity of the cold, either as it respects dress or their huts. The Scottish Highlander of the olden time, wrapped in his tartan, could sleep on the heather of the mountain side during a bitter sleety night without injury. After all, however, in the arctic regions the maintenance of life is a struggle; the depressing influences of cold, cheerless skies, and scanty food, tend to render the powers of the mind and the bodily frame alike stunted and undeveloped. Nature here holds out the means of life with a niggard hand, and it is from the sea principally that the supply of food and other necessaries are obtained. On the other hand, within the tropics the means of existence are lavishly bestowed, the stimulus of animal food is not required, while the earth yields its vegetable productions in abundance; but in these regions, no strong motive stimulating to active exertion, the mental powers become enfeebled, and all those vices inseparable from habitual indolence are engendered. It is in the temperate regions, where nature is not lavish, but liberal, and yet requires the hand of labour and the head of thought, that the human race is presented to us in its highest form, whether bodily or mentally considered. It is in such regions that arts attain to perfection; that science walks hand in hand with religion. A thousand necessities urge to exertion and enterprise, and these are followed by a due reward.
