There is another fact that should be noticed. The languages of Great Britain are reducible to two divisions, both of which agree in many essential points with certain languages or dialects of Continental Europe. The British was closely, the Gaelic more distantly, allied to the ancient tongue of the Gauls. From this affinity we get an argument _against_ any extreme antiquity of the Britons of the British Isles. The date of their separation from the tribes of the Continent was not so remote as to obliterate and annihilate all traces of the original mother-tongue. It was not long enough for the usual processes by which languages are changed, to eject from even the Irish Gaelic (the most unlike of the two) every word and inflection which the progenitors of the present Irish brought from Gaul, and to replace them by others. So that, at the first view, we have a limit in this direction; yet unless we have settled certain preliminaries, the limit is unreal. All that it gives us is the comparatively recent introduction of the _Keltic_ stock. Varieties of the human species, _other than Keltic_, may have existed at an indefinitely early period, and subsequently have been superseded by the Kelts. Philology, then, tells us little more than history; and it may not be superfluous to add, that the occupancy of Great Britain by a stock of the kind in question, earlier than the Keltic, and different from it, is no imaginary case of the author's, but a doctrine which has taken the definite form of a recognized hypothesis, and characterizes one of the best ethnological schools of the Continent--the Scandinavian.
