languages and dialects of the world. In such a Dictionary of Sound-Words, half the cases cited might very likely be worthless, but the collection would afford the practical means of expurgating itself; for it would show on a large scale what particular sounds have manifested their fitness to convey particular ideas, by having been repeatedly chosen among different races to convey them.
Attempts to explain as far as may be the primary formation of speech, by tracing out in detail such processes as have been here described, are likely to increase our knowledge by sure and steady steps wherever imagination does not get the better of sober comparison of facts. But there is one side of this problem of the Origin of Language on which such studies have by no means an encouraging effect. Much of the popular interest in such matters is centred in the question, whether the known languages of the world have their source in one or many primæval tongues. On this subject the opinions of the philologists who have compared the greatest number of languages are utterly at variance, nor has any one brought forward a body of philological evidence strong and direct enough to make anything beyond mere vague opinion justifiable. Now such processes as the growth of imitative or symbolic words form a part, be it small or large, of the Origin of Language, but they are by no means restricted to any particular place or period, and are indeed more or less in activity now. Their operation on any two dialects of one language will be to introduce in each a number of new and independent words, and words even suspected of having been formed in this direct way become valueless as proof of genealogical connexion between the languages in which they are found. The test of such genealogical connexion must, in fact, be generally narrowed to such words or grammatical forms as have become so far conventional in sound and sense, that we cannot suppose two tribes to have arrived at them independently, and therefore consider that both must have inherited them from a common source. Thus the
