§ =237.= Only very few examples occur of the sixteen-lined doubling of this stanza, according to the scheme _a b a b c d c d e f e f g h g h₂_; it occurs, e.g., in Moore, _When Night brings the Hour_. Another form of eight lines (_a b c d . a b c d₃_) is met with in Rossetti, _The Shadows _(ii. 249); it seems to be constructed on the analogy of a six-lined stanza (_a b c . a b c_), which is used pretty often. This stanza, which is closely allied to the tail-rhyme stanza described in § 238, consists most commonly of four-foot iambic verses; it occurs, e.g., in Campbell, _Ode to the Memory of Burns_ (p. 19): _Soul of the Poet! whereso'er Reclaim'd from earth, thy genius plume Her wings of immortality: Suspend thy harp in happier sphere, And with thine influence illume The gladness of our jubilee._ Specimens of forms of stanzas like this, consisting of other kinds of verse, e.g. of three-foot trochaic-dactylic verse, as in M. Arnold's _The Lord's Messenger_ (p. 231), are given in _Metrik_, ii, § 272. § =238.= From the four- and eight-lined bipartite equal-membered isometrical stanzas, dealt with in the preceding paragraphs, it will be convenient to proceed to the six-lined stanzas of similar structure. To these belongs a certain form of the tail-rhyme stanza, the nature and origin of which will be discussed when we treat of the chief form, which consists of unequal verses. The isometrical six-lined stanzas to be discussed here show the same structure as the common tail-rhyme stanza, viz. _a a b c c b_. An example is afforded in a song, Ritson, i. 10: _Sith Gabriel gan grete Ure ledi Mari swete, That godde wold in hir lighte, A thousand yer hit isse, Thre hundred ful iwisse, Ant over yeris eighte._ In Modern English this stanza occurs very often, e.g. in Drayton, _To the New Year_ (Poets, iii. 579); as a rule, however, it consists of four-foot iambic verses; e.g. in Suckling in a song (_Poets_, iii. 748): _When, dearest, I but think of thee, Methinks all things that lovely be Are present, and my soul delighted: For beauties that from worth arise, Are like the grace of deities, Still present with us though unsighted._ In this poem all the tail-verses are feminine throughout; in other cases there are masculine and feminine verses, more often we find masculine or feminine exclusively; but usually they interchange without any rule. Examples of these varieties, and also of similar stanzas consisting of three-foot trochaic verses, of two- and three-foot iambic-anapaestic, and of five-foot iambic lines are given in _Metrik_, ii, § 273. Stanzas of this form consisting of two-stressed verses occurring in Middle English poems have been quoted in § 65.
