Jet
Its virtues are thus described by Pliny, according to the version of Holland : In burning, the perfume thereof. chaseth away serpents, and bringeth women again that lie in a traunce by the suffocation or rising of the mother; the said smoke discovereth the falling sicknesse and bewraieth whether a young damsel be a maiden or no; the same being boiled in wine helpeth the toothache, and tempered with wax cureth the swelling glandules named the king's evil. They say that the magicians use this jeat stone much in their sorceries, which they practice by the means of red hot axes, which they call axinomancia, for they affirm that being cast thereupon it will burne and consume, if that ewe desire and wish shall happen accordingly." Jet is known in Prussia as black amber.
