"The bulk of the peoples now inhabiting India may have been the descendants of a new race from more northern latitudes, even perhaps, as argued by Mr. Tilak, from the Arctic regions; but there is nothing in the Veda, as there is nothing in the present ethnological features of the country, to prove that this descent took place near to the time of the Vedic hymns or was the slow penetration of a small body of fair-skinned barbarians into a civilized Dravidian peninsula."
