OBSERVATIONS.
OBS. 1.—The metres acknowledged in our ordinary schemes of prosody, scarcely amount, with all their "boundless variety," to more than one half, or three quarters, of what may be found in actual use somewhere. Among the foregoing examples, are some which are longer, and some which are shorter, than what are commonly known to our grammarians; and some, also, which seem easily practicable, though perhaps not so easily quotable. This last trochaic metre, so far as I know, has not been used alone,—that is, without longer lines,—except where grammarians so set examples of it in their prosodies.
OBS. 2.—"Trochaic of One foot," as well as "Iambic of One foot," was, I believe, first recognized, prosodically, in Brown's Institutes of English Grammar, a work first published in 1823. Since that time, both have obtained acknowledgement in sundry schemes of versification, contained in the new grammars; as in Farnum's, and Hallock's, of 1842; in Pardon Davis's, of 1845; in S. W. Clark's, and S. S. Greene's, of 1848; in Professor Fowler's, of 1850. Wells, in his School Grammar, of 1846, and D. C. Allen, in an other, of 1847, give to the length of lines a laxity positively absurd: "Rhymed verses," say they, "may consist of any number of syllables."—Wells, 1st Ed., p. 187; late Ed., 204; Allen, p. 88. Everett has recognized "The line of a single Trochee," though he repudiates some long measures that are much more extensively authorized.
