Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. With the view of rendering it, as far as possible, a complete handbook of the subject, he has also supplied an Appendix, illustrated by a philological map, presenting, so to say, a birdseye view Of all known languages, living and dead, and thus forming a clearly tabulated summary of its varied contents.
