We may, therefore, conclude that palæolithic man inhabited both Europe and India in the pleistocene age. And possibly the identity of the implements, in these two remote regions, may be accounted for in the same manner as the identity of Aryan root-words, by the view that their fabricators may have come from the same centre of dispersal, by the same routes as those which were subsequently used by the pre-Aryan, and Aryan, invaders of Europe and India. But whether this be accepted or not, it cannot be denied that the man who inhabited both these regions was in the same rude stage of human progress, and played his part in the same life-era. _Palæolithic Man lived in Palestine._ The discovery, by the Abbé Richard,[273] of a palæolithic flint implement, of the ordinary river-bed type, on the surface of a stratum of gravel between Mount Tabor and the lake of Tiberias, lends great weight to the view that the Aborigines of India and Europe, whose implements are found in the deposits of rivers, migrated from the same centre, since it bridges over the great interval of space by which they were isolated. It is very probable, that future discoveries may reveal the presence of a tolerably uniform priscan population, in the pleistocene age, throughout this vast area: which as yet has only been explored by archæologists in a few isolated points, with the important results recorded in the preceding pages. _Conclusion._ It now remains for us to sum up the results of the exploration of European caves, of which an imperfect outline has been given in this work. Their formation, and filling up, have an important bearing on the physical geography of the districts in which they occur, and reveal the great changes which are going on, in the calcareous rocks, at the present time. The study of the remains which they contain has led to the recognition of the fact, that the climate and geography of Europe, in ancient times, were altogether different from those of the present day.
