These diversities of natural genius, if real, must have great part of their foundation in the animal frame; and it has been often observed, that the vine flourishes, where, to quicken the ferments of the human blood, its aids are the least required. While spirituous liquors are, among southern nations, from a sense of their ruinous effects, prohibited; or from a love of decency, and the possession of a temperament sufficiently warm, not greatly desired; they carry in the north a peculiar charm, while they awaken the mind, and give a taste of that lively fancy and ardour of passion, which the climate is found to deny.

The melting desires, or the fiery passions, which in one climate take place between the sexes, are in another changed into a sober consideration, or a patience of mutual disgust. This change is remarked in crossing the Mediterranean, in following the course of the Mississippi, in ascending the mountains of Caucasus, and in passing from the Alps and the Pyrenees to the shores of the Baltic.

The female sex domineers on the frontier of Louisiana, by the double engine of superstition, and of passion. They are slaves among the native inhabitants of Canada, and are chiefly valued for the toils they endure, and the domestic service they yield. [Footnote: Charlevoix.]

The burning ardours, and the torturing jealousies of the seraglio and the haram, which have reigned so long in Asia and Africa, and which, in the southern parts of Europe, have scarcely given way to the difference of religion and civil establishments, are found, however, with an abatement of heat in the climate, to be more easily changed in one latitude, into a temporary passion which engrosses the mind, without enfeebling it, and excites to romantic achievements: by a farther progress to the north, it is changed into a spirit of gallantry, which employs the wit and the fancy more than the heart; which prefers intrigue to enjoyment; and substitutes affectation and vanity where sentiment and desire have failed. As it departs from the sun, the same passion is farther composed into a habit of domestic connection, or frozen into a state of insensibility, under which the sexes at freedom scarcely choose to unite their society.

These variations of temperament and character do not indeed correspond with the number of degrees that are measured from the equator to the pole; nor does the temperature of the air itself depend on the latitude. Varieties of soil and position, the distance or neighbourhood of the sea, are known to affect the atmosphere, and may have signal effects in composing the animal frame.

The climates of America, though taken under the same parallel, are observed to differ from those of Europe. There, extensive marshes, great lakes, aged, decayed, and crowded forests, with the other circumstances that mark an uncultivated country, are supposed to replenish the air with heavy and noxious vapours, that give a double asperity to the winter; and during many months, by the frequency and continuance of fogs, snow, and frost, carry the inconveniencies of the frigid zone far into the temperate. The Samoiede and the Laplander, however, have their counterpart, though on a lower latitude, on the shores of America: the Canadian and the Iroquois bear a resemblance to the ancient inhabitants of the middling climates of Europe. The Mexican, like the Asiatic of India, being addicted to pleasure, was sunk in effeminacy; and in the neighbourhood of the wild and the free, had suffered to be raised on his weakness a domineering superstition, and a permanent fabric of despotical government.

Great part of Tartary lies under the same parallels with Greece, Italy, and Spain; but the climates are found to be different; and while the shores, not only of the Mediterranean, but even those of the Atlantic, are favoured with a moderate change and vicissitude of seasons, the eastern parts of Europe, and the northern continent of Asia, are afflicted with all their extremes. In one season, we are told, that the plagues of an ardent summer reach almost to the frozen sea; and that the inhabitant is obliged to screen himself from noxious vermin in the same clouds of smoke in which he must, at a different time of the year, take shelter from the rigours of cold. When winter returns, the transition is rapid, and with an asperity almost equal in every latitude, lays waste the face of the earth, from the northern confines of Siberia, to the descents of Mount Caucasus and the frontier of India.

With this unequal distribution of climate, by which the lot, as well as the national character, of the northern Asiatic may be deemed inferior to that of Europeans, who lie under the same parallels, a similar gradation of temperament and spirit, however, has been observed, in following the meridian on either tract; and the southern Tartar has over the Tonguses and the Sanmoiede the same pre-eminence, that certain nations of Europe are known to possess over their northern neighbours, in situations more advantageous to both.

The southern hemisphere scarcely offers a subject of like observation. The temperate zone is there still undiscovered, or is only known in two promontories, the Cape of Good Hope and Cape Horn, which stretch into moderate latitudes on that side of the line. But the savage of South America, notwithstanding the interposition of the nations of Peru and of Mexico, is found to resemble his counterpart on the north; and the Hottentot, in many things, the barbarian of Europe: he is tenacious of freedom, has rudiments of policy, and a national vigour, which serve to distinguish his race from the other African tribes, who are exposed to the more vertical rays of the sun.

While we have, in these observations, only thrown out what must present itself on the most cursory view of the history of mankind, or what may be presumed from the mere obscurity of some nations, who inhabit great tracts of the earth, as well as from the lustre of others, we are still unable to explain the manner in which climate may affect the temperament, or foster the genius of its inhabitant.
