Of Ferrugine. chap. 46.

FErrugo is the pouder that falleth from the yron with filing, as squama is that thing that leapeth away from y^e fire with heating, and hath vertue to make dry and thin, and therefore it is good a∣gainst stopping of the splene. Neuerthe∣lesse it exciteth casting and spuing, when it is dronken, insomuch that sometime it bringeth to death, but if the violence therof be ceased with pouder of the Ada∣mas stone, or with water, in which the stone lyeth all night. Also it is sayd, that the pouder therof is best remedy against Emoroides: and also it stancheth the flixe of the wombe, as it is said in Platea. Also filing or pouder of yrō is called Rubigo, also Corrosio, & hath that name of Cor∣rudendo, fretting and gnawing: but it is properly called Erugo, and hath y^e name of Erodendo, filing, and not of Eramen∣to, as Isidore saith. And it infecteth and defileth the hand• that toucheth it, and maketh it soule. The more pure and po∣lished that yron is, the more rather it is defiled with rust, and worst to be clen∣sed. And rust is not soone done awaye, but in thrée manners. By burning of fire, or by fretting of a Salue or a File, or by froting of an hard stone, or by scouring of grauell and sand, and pullishing. And rust hath this propertie, that infection thereof commeth againe by light occasi∣on to the place in which it was first mo∣red and rooted.
