For example, I have come across tiresome grammarians who attempted to force prose into definite metres, as though it were a species of lyric poetry. Cicero, [*]( See Or. xx. 67, sqq. ) indeed, frequently asserts that the whole art of prose-structure consists in rhythm and is consequently censured by some critics on the ground that he would fetter our style by the laws of rhythm.
