RULE I.—COMPLEX MEMBERS.
When two or more complex members, or such clauses as require the comma in themselves, are constructed into a period, they are generally separated by the semicolon: as, "In the regions inhabited by angelic natures, unmingled felicity forever blooms; joy flows there with a perpetual and abundant stream, nor needs any mound to check its course."—Carter. "When the voice rises, the gesture naturally ascends; and when the voice makes the falling inflection, or lowers its pitch, the gesture follows it by a corresponding descent; and, in the level and monotonous pronunciation of the voice, the gesture seems to observe a similar limitation, by moving rather in the horizontal direction, without much varying its elevation."—Comstock's Elocution, p. 107.
"The wide, the unbounded prospect lies before me;
But shadows, clouds, and darkness, rest upon it."—Addison.
