of Germany itself? Scarcely to be found, except on the shores of the Baltic: elsewhere the ordinary European type prevails, olive skin and _cheveux châtains_. “I sought for the fair population of classical Germany in vain,” says Niebuhr, “until I found it in Scandinavia.” On the other hand, the Greek in Provence, the Moor in Spain, Southrons, transplanted into those countries in no very great numbers, have impressed their type on the general population, and, as it were, changed the very breed. When dark and fair intermix, the odds seem to be greatly in favour of the dark complexion prevailing in the offspring. We heard lately of a society formed in France for the conservation of the “Xanthous,” or yellow-haired variety of the human race, which they regard as the true aristocracy of nature, and rightly conceive to be threatened with extinction: their object to be attained by portioning from time to time blonde maidens who might take to themselves husbands of the same complexion. Even so—to return to our trees—the meridional vegetation gradually drives back that of the North in the battlefield of species. If we figure to ourselves the appearance of the plains of England two thousand years ago, with their indigenous vegetable covering only—without the common elm, the linden, plane, sycamore, poplar, acacia, chestnut, fruit-trees of every kind, and cultivated plants in general—without, probably, a single species of pine or fir, or indeed any evergreen but box, yew, and holly—and remember that every foreign plant has displaced a native, we may gather some idea of the conquests which the South has effected even here, not indeed without the aid of human industry, but in part by sheer physical superiority. But on the Mediterranean coast these conquests have been much more marked. Take the following description of the change which two thousand years have made in the common flora of Greece, from the work of a German botanist (Fraas, Klima und Pflanzenwelt):—
