Caul \Caul\ (k[add]l), n. [OE. calle, kelle, prob. fr. F. cale;
   cf. Ir. calla a veil.]
   1. A covering of network for the head, worn by women; also, a
      net. --Spenser.

   2. (Anat.) The fold of membrane loaded with fat, which covers
      more or less of the intestines in mammals; the great
      omentum. See {Omentum}.

            The caul serves for the warming of the lower belly.
                                                  --Ray.

   3. A part of the amnion, one of the membranes enveloping the
      fetus, which sometimes is round the head of a child at its
      birth.

            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.
