In the same way no one is capable of proving or discovering the geographical site of the one lost source in Paradise, whence those four rivers took their rise, which are in part to be still traced on the earth. As to the Hebrew language, I think that a deeper inquiry would shew that it is not so far removed from the Indo-Greek family; and that it is even partially related to it, although this affinity may be at first very much concealed by the great difference of structure, and by the total diversity of grammatical forms. In general we must not endeavour to enforce, with too rigid uniformity and too systematic precision, the division of languages here marked out. It suffices to adhere to one general point of survey; but in other respects so luxuriant, so various, so irregular has been the growth of the human mind in the region of languages, that it may be compared to the expansive life of free, uncultivated nature, to the wild variety of the thick-grown forest or of the flowery meadow. To the second order of languages of the Indo-Greek race, _probably_ belongs the great Sclavonian family of languages, which, after the others, would form the fourth member in this class; but a definite and decisive judgment on this matter, I must leave to those philologists who are perfectly conversant with this branch of human speech. Between the second and third class of languages, there are a multitude of intermediate tongues which have sprung up out of that intermixture of races and nations, occurring at all periods of history, and necessarily affecting more or less language itself. I allude particularly to such languages as are not perfectly monosyllabic, and which have nevertheless a very simple and imperfect, or even a very irregular, strange, and awkward grammatical structure. Such for instance are some of the American languages, which in this respect at least cannot be ranked in the third class, while they do not bear a closer, or at all close, affinity to those of the second. Most of the fragments of the earlier languages of Europe which are still extant, belong to this intermediate class of tongues partaking of both those species, or at least holding a middle place between them. Such are the Celtic or Gælic languages, the Finnish and other ancient remnants of language, which must not escape the study of the philologist, whose judgment is too frequently warped by some patriotic partiality or some learned predilection.
