Of Reyben. cap. 86.
REyben as Auicen saith, is a little stone and is found in a Crabs head, and is sometime whife, and is sometime some deale yeolow, and is softe in sub∣staunce, little harder than the blacke of a fishes eye, and is in shape round & plaine without, and some deale hollow within, and is in vertue kindly cold & moist, and helpeth against biting of Scorpions, and of the wesell, if it be beaten & laid ther∣to in plaister wise. Also it is sayd, it hel∣peth against the biting of a mad dogge, if the pouder thereof be taken in drink. If the pouder thereof be burnt, it clean∣seth téeth, and drieth wounds, and help∣eth scabs, and letteth teares.
