    • 1841, George Chalmers, Daniel Defoe, The Novels and Miscellaneous Works, page 84:
      He could see no great harm in the present pretenders to magic, if the poor people would but keep their money in their pockets; and that they should have their pockets picked by such an unperforming, unmeaning, ignorant crew as these are, is the only magic De Foe could see in the whole science.
