This treatise, designed for advanced classes in English Grammar, is given to the public with the hope that it may contribute somewhat to the philosophical study of our language. A systematic analysis of the English Sentence, should hold a prominent rank, merely as an important means of mental development. In this respect no branch of study has been regarded so dry and sterile. A few years ago the attainments of most teachers in grammar were, to the last degree, superficial, and their instructions systematically wrong. The student of Kirkham supposed that his order of parsing exhausted the subject, and the disciple of Murray knew far more of rules than relations.
