to the common grammarians, or according to his own Dictionary, the number will be ten.  And this distribution, which was adopted by Dr. Ash about 1765, by Murray the schoolmaster about 1790, by Caleb Alexander in 1795, and approved by Dr. Adam in 1793, has since been very extensively followed; as may be seen in Dr. Crombie’s treatise, in the Rev. Matt.  Harrison’s, in Dr. Mandeville’s reading-books, and in the grammars of Harrison, Staniford, Alden, Coar, John Peirce, E. Devis, C. Adams, D. Adams, Chandler, Comly, Jaudon, Ingersoll, Hull, Fuller, Greenleaf, Kirkham, Ferd.  H. Miller, Merchant, Mack, Nutting, Bucke, Beck, Barrett, Barnard, Maunder, Webber, Emmons, Hazen, Bingham, Sanders, and many others.  Dr. Lowth’s distribution is the same, except that he placed the adjective after the pronoun, the conjunction after the preposition, and, like Priestley, called the participle a verb, thus making the parts of speech nine.  He also has been followed by many; among whom are Bicknell, Burn, Lennie, Mennye, Lindley Murray, W. Allen, Guy, Churchill, Wilson, Cobbett, Davis, David Blair, Davenport, Mendenhall, Wilcox, Picket, Pond, Russell, Bacon, Bullions, Brace, Hart, Lyon, Tob.  H. Miller, Alger, A. Flint, Folker, S. Putnam, Cooper, Frost, Goldsbury, Hamlin, T. Smith, R. C. Smith, and Woodworth.  But a third part of these, and as many more in the preceding list, are confessedly mere modifiers of Murray’s compilation; and perhaps, in such a case, those have done best who have deviated least from the track of him whom they professed to follow.[72]

9.  Some seem to have supposed, that by reducing the number of the parts of speech, and of the rules for their construction, the study of grammar would be rendered more easy and more profitable to the learner.  But this, as would appear from the history of the science, is a mere retrogression towards the rudeness of its earlier stages.  It is hardly worth while to dispute, whether there shall be nine parts of speech or ten; and perhaps enough has already been stated, to establish the expediency of assuming the latter number.  Every word in the language must be included in some class, and nothing is gained by making the classes larger and less numerous.  In all the artificial arrangements of science, distinctions are to be made according to the differences in things; and the simple question here is, what differences among words shall be at first regarded.  To overlook, in our primary division, the difference between a verb and a participle, is merely to reserve for a subdivision, or subsequent explanation, a species of words which most grammarians have recognized as a distinct sort in their original classification.
