There is one that has warrant to wait on you still.
Back, back,
The volume black!
I have a warrant to carry it back.
Most of these stanzas admit of being looked upon as tripartite on account of the bipartite structure of the frons.
Other stanzas may be viewed as consisting of three unequal parts (if not regarded as bipartite); such, for instance, is the stanza on the scheme (a) ~ A ~ (b) ~ B ~4 c1 (d) D4 b ~1 e e e c c2 C4 occurring in Shelley’s Autumn, A Dirge (iii. 65), where the symbols (a)and (b) denote middle rhymes.
Stanzas of this kind are met with also in modern poetry, as e.g. in Thackeray, Mrs. Browning, and Rossetti (cf. Metrik, ii, §§ 353, 354).
