This Grammar makes no pretence whatever of being an original and exhaustive treatise on the subject. In a book of this kind there is practically no scope for a display of either of these features, but I have contrived to bring within a comparatively small space a great deal of matter which will be new to students, and especially to those who are unable to study the subject in works written in foreign languages. All that I have attempted to do is to furnish our countrymen with a systematic and scientific treatment of Comparative Greek Grammar based upon the philological books and articles of the best workers of the present day in the wide field of Comparative Philology. Specialists in the subject will accordingly find little that is new in the book. In Greek as in all the other indo-germanic languages there are still innumerable points which have never been satisfactorily explained, and not a few points about which there is a great divergence of opinion even among the best philologists. In all such cases I have carefully considered the various explanations which have been proposed, and have given those with which I agreed without, as a rule.
