SECTION VIII.—THE CURVES.

The Curves, or Marks of Parenthesis, are used to distinguish a clause or hint that is hastily thrown in between the parts of a sentence to which it does not properly belong; as, "Their enemies (and enemies they will always have) would have a handle for exposing their measures."—Walpole.

"To others do (the law is not severe)
What to thyself thou wishest to be done."—Beattie.

OBS.—The incidental clause should be uttered in a lower tone, and faster than the principal sentence. It always requires a pause as great as that of a comma, or greater.
