         It is deemed lucky to be with a caul or membrane
         over the face. This caul is esteemed an infallible
         preservative against drowning . . . According to
         Chysostom, the midwives frequently sold it for magic
         uses.                                 --Grose.
         I was born with a caul, which was advertised for
         sale, in the newspapers, at the low price of fifteen
         guineas.                              --Dickens.
