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,
