must have degenerated, or rather felt the influence of the climate; under a milder sky their dispositions have become milder; every excess in them has been tempered, and by these changes they have become more conformable to the nature of the country which they inhabit. The vegetables which cover this earth and are more connected with it than the animal that feeds upon them, partake in a superior degree of the nature of the climate. Every country, every degree of temperature, has its particular plants. At the foot of the Alps we find those of France and Italy, and on their summit those of the northern regions, which very plants we also meet with on the frozen pinnacles of the African mountains. On the south side of the mountains which separate the Mogul empire from the kingdom of Cashmire, we see all the plants of the Indies, and on the other side we are surprised to find none but those of Europe. It is from intemperate climates that we also derive drugs, perfumes, poisons and all the plants whose qualities are excessive. The productions of temperate climates, on the contrary are always mild. Of such happy spots, herbs and roots the most wholesome, the sweetest fruits, the gentlest animals and the most polished men, are the delightful appurtenances. Thus the earth produces plants, the earth and plants make animals, and of the earth, plants, and animals, are formed men; for the qualities of vegetables, proceed immediately from the soil and air; the temperament and other relative qualities of animals which feed on herbs, have a close affinity to the particular kinds they use, and the physical qualities of men, and other animals which subsist on flesh, as well as on vegetables, depend, though more remotely, on the same causes, whose influence extends even to disposition and manners. Size and form, which appear to be absolute and determined qualities, depend, nevertheless, like the relative qualities upon the influence of the climate. The size of our largest animals are greatly inferior to that of the elephant, rhinoceros, or hippopotamus; our largest birds are but small if we compare them with the ostrich, condor, or the cassowary; and what comparison can be made between the fishes, lizards, and serpents of our regions, and the whale, the walrus, and manati, which inhabit the northern seas; or the crocodiles, large lizards, and enormous adders which infest the southern climes, both by land and water? And if we consider each species in different climates, we shall find sensible varieties both in size and figure, as we have already evinced in the history of the horse, goat, hog, and dog. These changes are, however, produced but slowly and imperceptibly; the grand workman of nature is Time, and his operations are equal, uniform, and regular; he performs nothing by starts; nothing but by degrees, by shades, and by succession; and what he does, however imperceptible at first, becomes gradually sensible, and is, at length,
