If both rhythmical sections of a tetrameter are brachycatalectic we get one of the four varieties of the Middle English Alexandrine--the only one that has continued in use in Modern English poetry. Alexandrine: _Mid ývernésse and prúde | and ýssing wés that ón; He núste nouht þát he wés | bóþe gód and món._ The Passion of our Lord, ll. 35, 36. _Of Álbion's glórious ísle | the wónders whílst I wríte, The súndry várying sóils, | the pléasures ínfiníte._ Drayton, Polyolbion, ll. 1, 2. These are the principal forms of rhythmical sections made up of disyllabic feet that occur in Middle English and Modern English Poetry. § =78. The breaking up of these long lines= (consisting of two rhythmical sections) into shorter lines is usually effected by rhyme. Thus, if both rhythmical sections of the acatalectic tetrameter are divided by what is called leonine rhyme we get the short four-foot couplet imitated from the French _vers octosyllabe_, as in the following verses taken from the Middle English _A lutel soth sermon_ (ll. 17-20): _He máde him ínto hélle fálle, And éfter hím his chíldren álle; Þér he wás fortó ure dríhte Hine bóhte míd his míhte._ A Modern English example is-- _Amóngst the mýrtles ás I wálk'd, Lóve and my síghs thus íntertálk'd: 'Téll me,' said Í in déep distréss, 'Where I may fínd my shépherdéss.'_ Carew, Poets, iii, p. 703. Another stanza of four lines is formed when the first rhythmical sections of two tetrameters rhyming together are also connected in the corresponding place (viz. before the caesura) by another species of rhyme, called _interlaced_ or _crossed_ rhyme (_rime entrelacée_): _I spéke of Ihésu of hévene withín; Off álle kýngys he is flóur; Þat súffryd déþ for álle mankýn, He ís our alle créatóur._ Saynt Katerine, ii, ll. 89-92. Cf. these verses with an earlier version of the same legend (quoted p. 127), where only the second sections are connected by rhyme. A Modern English example is-- _When yóuth had léd me hálf the ráce That Cúpid's scóurge had máde me rún; I lóoked báck to méte the pláce From whénce my wéary cóurse begún._ Surrey, Restless Lover, p. 4, ll. 1-4. Corresponding short trochaic lines result from the acatalectic trochaic tetrameter broken by leonine or inserted rhyme. In Middle English poetry, however, they occur but very seldom in their pure form, i.e. with disyllabic rhymes; in most cases they have monosyllabic or alternate monosyllabic and disyllabic rhymes. In like manner the catalectic iambic tetrameter is broken up by inserted rhyme into two short verses, viz. one of four feet with a monosyllabic ending, and one of three feet with a disyllabic ending, as in the following examples:
