Grocott & Ward, comps. Grocott’s Familiar Quotations, 6th ed. 189-?.


Nor aught so good, but, strain’d from that fair use,
Revolts from true birth, stumbling on abuse.
Shakespeare.—Romeo and Juliet, Act II. Scene 2. (Friar Lawrence at his cell door.)

When you abuse another do you ne’er look back upon yourself?
Plautus.—Pseudolus, Act II. Scene 2, Line 18.
