By what road did the first Colonists of Europe reach their final destination? Adelung has inferred that Europe was peopled exclusively from the Steppes of Northern Asia. But for this opinion, it does not seem that any valid reason can be assigned. If we assume Central Asia to have been the focus of migration, it will be observed that there are three routes by which the forefathers of the European nations may have arrived in their final abodes, viz. 1, The Steppes of Northern Asia; 2, Asia Minor and the Hellespont; and 3, The Isthmus of Suez, the North of Africa, and the Straits of Gibraltar. For concluding that either of these three routes was used, to the exclusion of the other two, it would not be easy to point out any strong argument based on Geographical grounds. Now if the third was employed at all it may be inferred that some of the European nations may be even more nearly allied to those of Africa than they are to the Asiatic populations. To this conclusion, however, a formidable objection occurs in the strikingly contrasted Physiology of Africa and Europe, for—even though it should be conceded that these opposite features do not serve to prove an aboriginal difference of race—the question still arises whether they do not, nevertheless, furnish evidence that the nations of these two continents are more remotely related than any other branches of the Human Family; whether they do not point to the inference that the inhabitants of the South and West of Asia—who certainly occupy an intermediate place Physiologically—must not also be regarded as forming a connecting link between those of Europe and Africa in a Genealogical and Historical sense? To these inquiries it will be obvious that the facts just adverted to furnish a very distinct answer, for from those facts it directly follows—not only that climate and other existing causes are sufficient to account for the different Physical peculiarities of the inhabitants of Africa and Europe—but it also follows from the same evidence, that a period of time far short of that during which the European and African nations are known to have occupied their present abodes, would have sufficed to superinduce the opposite characteristics they now display! Perhaps it may be inferred, though probably the subject does not admit of a precise conclusion on this head, that in a suitable climate the lapse of 500 or 600 years might be more than adequate to engraft on the physiognomy of Southern Asia all the distinctive peculiarities of the Negro. That these peculiarities had been fully developed in an early era of the History of the World, is manifest from the Egyptian Paintings, in many of which we have individuals of this ill-fated race very vividly depicted, appearing sometimes as tributaries, and on other occasions as captives, leashed together like hounds!
