18. How many different schemes of classification this author invented, I know not; but he might well have saved himself the trouble of inventing any; for, so far as appears, none of his last three grammars ever came to a second edition. In the sixth edition of his “Plain and Comprehensive Grammar, grounded on the true principles and idioms of the language,” a work which his last grammatical preface affirms to have been originally fashioned “on the model of Lowth’s,” the parts of speech are reckoned “six; nouns, articles, pronouns, adjectives, verbs, and abbreviations or particles.” This work, which he says “was extensively used in the schools of this country,” and continued to be in demand, he voluntarily suppressed; because, after a profitable experiment of four and twenty years, he found it so far from being grounded on “true principles,” that the whole scheme then appeared to him incorrigibly bad. And, judging from this sixth edition, printed in 1800, the only one which I have seen, I cannot but concur with him in the opinion. More than one half of the volume is a loose Appendix composed chiefly of notes taken from Lowth and Priestley; and there is a great want of method in what was meant for the body of the work. I imagine his several editions must have been different grammars with the same title; for such things are of no uncommon occurrence, and I cannot otherwise account for the assertion that this book was compiled “on the model of Lowth’s, and on the same principles as [those on which] Murray has constructed his.”—Advertisement in Webster’s Quarto Dict., 1st Ed.
