"Let me correct a story relating to the great duke of Marlborough. The duchess was pressing the duke to take a medicine, and with her usual warmth said, "I'll be hanged if it do not prove serviceable." Dr. Garth, who was present, exclaimed, "Do take it then my lord duke; for it must be of service, in one way or the other.""
