Ánd I sérve the fáiry quéen,
To déw her órbs upón the gréen, &c.
The two first lines belong to the first, the following to the latter species. Sometimes the rhythm of such rhymed four-foot verses is purely trochaic, e.g. in the witches’ song in Macbeth, IV, sc. i.
There are also unrhymed iambic lines of four feet, which usually have a caesura in the middle; e.g.:
The mátch is máde, | and áll is dóne. Shrew, IV. iv. 46.
Befóre the kíngs | and quéens of France. Hen. VI, I. vi. 27.
Not unfrequently, however, such verses only apparently have four feet, one missing foot or part of it being supplied by a pause (cf. Metrik, ii, § 164):
He’s tá’en ⏑–́ (Shout). || And hark! | they shóut for jóy.
Caes. V. iii. 32.
Mal. As thóu didst léave it. –́|| Serg. Dóubtful it stóod.
