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 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 foot after a strong pause is 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 mclude the sensitive second foot, it must be due either to great want of ear or else is a calculated effect, the superinducmg or mounting of a new rhythm upon the old; and since the new or mounted rhythm is actually heard and at the same time the mind naturally supplies the natural or standard foregoing rhythm, for we do not forget what the rhythm is that by rights we should be hearing, two rhythms are in some manner running at once and we have something answarble to counterpoint in music, which is two or more strains of tune going on together, and this is Counterpoint Rhythm. Of this kind of verse Milton is the great master and the choruses of Samson Agonistes are wntten throughout
