Of a Whetstone. cap. 23.
A Whetstone is called Cos, and hath that name, for it whetteth and shar∣peth yron to cut and to carue. For Cotis is Greeke, and is to say, caruing, as Isi∣dore saith. And there be diuerse manner of Whetstones. And some neede Water and some neede Oyle for to whet, but Oyle: maketh smooth, and water maketh the edge right sharpe, as Isidore sayeth, lib. codem. capitulo. 3. The Whetstone hath this propertie, that it serueth ano∣ther thing in whet••ing, and wasteth him∣selfe some and some, as Gregory sayeth. The powder of the Whetstone helpeth well in medicine, and hath vertue of dri∣eng, and of smiting againe repercussiue, and of staunching of bloud, as Constan∣tine saith.
(* 1.1The ponder of a Whetstone is as good for a fresh wound to stape the blée∣ding, as is a Pigges turde to the nose of him that bléedeth: for the gréet of the one is a pricking in the wound, & the stench of the other, anoyance to the head.)
