Common English rhythm, called Running Rhythm above, is measured by feet of either two or three syllables and (putting aside the imperfect feet at the beginning and end of lines and also some unusual measures, in which feet seem to be paired together and double or composite feet to arise) never more or less. Every foot has one principal stress or accent, and this or the syllable it falls on may be called the Stress of the foot and the other part, the one or two unaccented syllables, the Slack. Feet (and the rhythms made out of them) in which the stress comes first are called Falling Feet and Falling Rhythms, feet and rhythm in which the slack comes first are called Rising Feet and Rhythms, and if the stress is between two slacks there will be Rocking Feet and Rhythms. These distinctions are real and true to nature; but for purposes of scanning it is a great convenience to follow the (2) example of music and take the stress always first, as the accent or the chief accent always comes first in a musical bar. If this is done there will be in common English verse only two possible feet--the so-called accentual Trochee and Dactyl, and correspondingly only two possible uniform rhythms, the so-called Trochaic and Dactylic. But they may be mixed and then what the Greeks called a Logaoedic Rhythm arises. These are the facts and according to these the scanning of ordinary regularly-written English verse is very simple indeed and to bring in other principles is here unnecessary. But because verse written strictly in these feet and by these principles will become same and tame the poets have brought in licences and departures from rule to give variety, and especially when the natural rhythm is rising, as in the common ten-syllable or five-foot verse, rhymed or blank. These irregularities are chiefly Reversed Feet and Reversed or Counterpoint Rhythm, which two things are two steps or degrees of licence in the same kind. By a reversed foot I mean the putting the stress where, to judge by the rest of the measure, the slack should be and the slack where the stress, and this is done freely at the beginning of a line and, in the course of a line, after a pause; only scarcely ever in the second foot or place and never in the last, unless when the poet designs some extraordinary effect; for these places are characteristic and sensitive and cannot well be touched. But the reversal of the first foot and of some middle (3) foot after a strong pause is a thing so natural that our poets have generally done it, from Chaucer down, without remark and it commonly passes unnoticed and cannot be said to amount to a formal change of rhythm, but rather is that irregularity which all natural growth and motion shews. If however the reversal is repeated in two feet running, especially so as to include the sensitive second foot, it must be due either to great want of ear or else is a calculated effect, the super- inducing or mounting of a new rhythm upon the old;
