_O sylvan prophet! whose eternal fame Echoes from Judah's hills and Jordan's stream, The music of our numbers raise, And tune our voices to thy praise._ Other schemes that occur are _a a₄ b b₅_, _a a b₄ b₅_, _a a b₄ b₂_, _a a₄ b₃ b₂_, _a₄ a₂ b b₄_, _a₅ a₃ b b₅_; there are even forms with lines of unequal length in each part, as e.g.: _a₄ a₅ b₇ b₅_, _a₇ a₄ b₂ b₆_, _a₅ a₃ b₅ b₄_, _a₅ a₄ b₄ b₆_. For examples see _Metrik_, ii (§§ 322-4). Enclosing rhymes are also found; and in this case the lines of the same length usually rhyme together, as in the formula _a₃ b b₅ a₃_ in Mrs. Hemans, _The Song of Night_ (vi. 94): _I come to thee, O Earth! With all my gifts!--for every flower sweet dew In bell, and urn, and chalice, to renew The glory of its birth._ Sometimes verses are used partly of unequal length: _a₃ b₅ b₃ a₄_ in M. Arnold, _A Nameless Epitaph_ (p. 232), or _a₅ b₂ b₄ a₅_, _a b b₄ a₃_, &c. (cf. _Metrik_, ii, § 325). § =258.= Stanzas of this kind frequently occur with crossed rhymes. Most commonly two longer verses are placed between two shorter ones, or vice versa; thus we have the formula _a₃ b a₅ b₃_ in Southey's _The Ebb-Tide_ (ii. 193): _Slowly thy flowing tide Came in, old Avon! scarcely did mine eyes, As watchfully I roam'd thy green-wood side, Perceive its gentle rise._ Other forms are _a₂ b a₃ b₂_, _a₄ b a₅ b₄_, _a₅ b a₄ b₅_ (cf. _Metrik_, ii, § 326). Three isometrical verses and one shorter or longer end-verse can also be so connected, as e.g. on the scheme _a b a₄ b₂_ in Pope, _Ode on Solitude_ (p. 45): _Happy the man whose wish and care A few paternal acres bound, Content to breathe his native air, In his own ground_; or in Cowper on the model _a b a₄ b₅_ in _Divine Love endures no Rival_ (p. 418): _Love is the Lord whom I obey, Whose will transported I perform; The centre of my rest, my stay, Love's all in all to me, myself a worm._ Similar stanzas both with this and other arrangements of rhymes (as e. g. _a b a₅ b₃_, _a b a₄ b₂_, _a b a₃ b₅_) are very popular. A specimen of the first of these formulas is found in M. Arnold's _Progress_ (p. 252), and one of the second in his _A Southern Night_ (p. 294). For other examples see _Metrik_, ii, §§ 326-7. More rarely a short verse begins the stanza (e.g. _a₃ b a b₅_ in Mrs. Hemans, _The Wish_, vi. 249), or is placed in the middle on the scheme _a₅ b₂ a b₅_ (as in G. Herbert, _Church Lock and Key_, p. 61). For specimens see _Metrik_, ii, §§ 328, 329. Stanzas of one isometrical and another anisometrical half are not frequently met with; a specimen of the form _a b₄ a₅ b₂_ is found in G. Herbert's _Employment_ (p. 51). More common are stanzas of two anisometrical halves; in this case either the two middle or the isolated verses are generally isometrical; e.g. on the scheme _a₅ b a₄ b₃_ in G. Herbert, _The Temper_ (p. 49):
