the English heroick admits of acute or grave syllables variously disposed. The Latin never deviates into seven feet, or exceeds the number of seventeen syllables; but the English Alexandrine breaks the lawful bounds, and surprises the reader with two syllables more than he expected.
The effect of the Triplet is the same; the ear has been accustomed to expect a new rhyme in every couplet; but is on a sudden surprized with three rhymes together, to which the reader could not accommodate his voice, did he not obtain notice of the change from the braces of the margins. Surely there is something unskilful in the necessity of such mechanical direction.
Considering the metrical art simply as a science, and consequently excluding all casualty, we must allow that Triplets and Alexandrines, inserted by caprice, are interruptions of that constancy to which science aspires. And though the variety which they produce may very justly be desired, yet, to make our poetry exact, there ought to be some stated mode of admitting them.
