7.  The old scheme of the Latin grammarians has seldom, if ever, been literally followed in English; because its distribution of the parts of speech, as declined and undeclined, would not be true with respect to the English participle.  With the omission of this unimportant distinction, it was, however, scrupulously retained by Dilworth, by the author of the British Grammar, by William Ward, by Buchanan, and by some others now little known, who chose to include both the article and the adjective with the noun, rather than to increase the number of the parts of speech beyond eight.  Dr. Priestley says, “I shall adopt the usual distribution of words into eight classes; viz.  Nouns, Adjectives, Pronouns, Verbs, Adverbs, Prepositions, Conjunctions, and Interjections.[71] I do this in compliance with the practice of most Grammarians; and because, if any number, in a thing so arbitrary, must be fixed upon, this seems to be as comprehensive and distinct as any.  All the innovation I have made hath been to throw out the Participle, and substitute the Adjective, as more evidently a distinct part of speech.”—­Rudiments of English Gram., p. 3.  All this comports well enough with Dr. Priestley’s haste and carelessness; but it is not true, that he either adopted, “the usual distribution of words,” or made an other “as comprehensive and distinct as any.”  His “innovation,” too, which has since been countenanced by many other writers, I have already shown to be greater, than if, by a promotion of the article and the adjective, he had made the parts of speech ten.  Dr. Beattie, who was Priestley’s coeval, and a much better scholar, adopted this number without hesitation, and called every one of them by what is still its right name:  “In English there are ten sorts of words, which are all found in the following short sentence; ’I now see the good man coming; but, alas! he walks with difficulty.’ I and he are pronouns; now is an adverb; see and walks are verbs; the is an article; good, an adjective; man and difficulty are nouns, the former substantive, the latter abstract; coming is a participle; but, a conjunction; alas! an interjection; with, a preposition.  That no other sorts of words are necessary in language, will appear, when we have seen in what respects these are necessary.”—­Beattie’s Moral Science, Vol. i, p. 30.  This distribution is precisely that which the best French grammarians have usually adopted.

8.  Dr. Johnson professes to adopt the division, the order, and the terms, “of the common grammarians, without inquiring whether a fitter distribution might not be found.”—­Gram. before 4to Dict., p. 1.  But, in the Etymology of his Grammar, he makes no enumeration of the parts of speech, and treats only of articles, nouns, adjectives, pronouns, and verbs; to which if we add the others, according
