in Medicine, small long worms which breed in the muscular parts of the arms and legs, called Guinea worms. The common way of getting out these worms is by the point of a needle; and to prevent their forming there again, the usual custom is to wash the parts with wine or vinegar, with alum, nitre, or common salt, or with a strong lixivium of oak ashes, and afterwards anointing them with an ointment of the common kind used for scrofulous eruptions, with a small mixture of quicksilver.
