“ Like some of the rest of us, she never reflected how balefully her evil mood might operate; and that all things work for good in the end, will not cover those by whom come the offenses. Another night's rest, it is true, sent the evil mood to sleep again for a time, but did not exorcise it; for there are demons that go not out without prayer, and a bad temper is one of them--a demon as contemptible, mean-spirited, and unjust, as any in the peerage of hell--much petted, nevertheless, and excused, by us poor lunatics who are possessed by him. ”
