ANIMALS COMMON TO BOTH CONTINENTS. By the preceding enumeration it appears, that not only the quadrupeds of the hot climates of Asia and Africa, but many of those in the temperate climates of Europe, are strangers in America; but we find many there of such as can support cold and propagate their species in the regions of the north; and though there is an evident difference in them they cannot but be considered as the same animals; and this induces us to believe, they formerly passed from one continent to the other by lands still unknown, or possibly long since buried by the waves. Of the contiguity of the two northern provinces, the proof thus drawn from Natural History is a stronger confirmation than all the conjectures of speculative Geography. The Bears of the Illinois, of Louisiana, &c. seem to be the same with ours; the former being only smaller and blacker. The stag of Canada, though smaller than ours, differs only in the superior loftiness of his horns, number of antlers, and length of his tail. The roe-buck, found in the south of Canada, and in Louisiana, is also smaller and has a longer tail than that of Europe. The Orignal is the same animal as the Elk, but not so large. The rein-deer of Lapland, the fallow-deer of Greenland, and the Caribou of Canada, appear to be one and the same animal. Brisson has indeed classed the latter with the _cervus Burgundicus_ of Johnston, but which animal remains unknown, and possibly received that name from accident or caprice. The hares, squirrels, hedge-hogs, otters, marmots, rats, shrew-mice, and the moles, are species which may be considered as common to both continents; though there is not one perfectly similar in America, to what it is in Europe; and it is very difficult, if not impossible, to pronounce whether they are in reality different species, or mere varieties rendered permanent by the influence of the climate.
