that was left of Celtic nationality was either absorbed by the intruders, or forced aside and driven to take refuge in mountain fastnesses and outlying islands. Besides all these, there was still another wave, which is supposed to have passed between the Sea of Aral and the Caspian, and, keeping still further to the north and east, to have passed between its kindred Teutons and the Mongolian tribes, and so to have lain in the background until we find them appearing as Slavonians on the scene of history. Into so many great stocks did the Western Aryans pass, each possessing strongly marked nationalities and languages, and these seemingly so distinct that each often asserted that the other spoke a barbarous tongue. But, for all that, each of those tongues bears about with it still, and in earlier times no doubt bore still more plainly about with it, infallible evidence of common origin, so that each dialect can be traced up to that primeval form of speech still in the main preserved in the Sanscrit by the Southern Aryan branch, who, careless of practical life, and immersed in speculation, have clung to their ancient traditions and tongue with wonderful tenacity. It is this which has given such value to Sanscrit, a tongue of which it may be said that if it had perished the sun would never have risen on the science of comparative philology. Before the discoveries in Sanscrit of Sir William Jones, Wilkins, Wilson, and others, the world had striven to find the common ancestor of European languages, sometimes in the classical, and sometimes in the Semitic tongues. In the one case the result was a tyranny of Greek and Latin over the non-classical tongues, and in the other the most uncritical and unphilosophical waste of learning.
