Now how, and by what means every thing is to bee preserved, and kept from hurt, wee must know, that many things are to bee preserved in the Earth, and especially all rootes doe for a long time remaine in the Earth without losing their vertue, or being corrupted: in like manner herbs, flowers, and all fruites continue in the water incorrupted, and green: there are also many fruits, and apples that may be preserved in water from all manner of putrefaction, untill new fruit come againe. [Sidenote: How to preserve flesh and blood.] So also flesh, and blood, which indeed are putrefied, and grow unsavoury quickly, are preserved in cold fountain-water, and not only so, but by the addition of new and fresh fountaine-water, may be turned into a quintessence, and bee forever preserved from putrefaction, and an ill savour, without any balsome. And this doth not only preserve the flesh, and blood of dead things, but also of the living, wherefore Mans body may bee preserved from all manner of putrefaction, and divers diseases that proceed from putrefaction, better then common Mummie. Now that blood may be preserved of it self from putrefaction, and stinking, and not as a quintessence, & so as it may preserve the blood of the living (as we now said) thou must follow this processe. [Sidenote: How the Arcanum of mans blood is to be prepared.] Let the blood bee separated from its flegm, which is separated of its selfe, and is driven to the upper part. This water poure gently out of the vessell, and in stead of it put as much of the water of the salt of blood, which water wee teach to make in our Chirurgerie: That water doth presently mixe with the blood, and preserves it so, that it will never bee putrefied, or grow unsavory, but continue many years as fresh, and very red as it was the first day: and this indeed is a great wonder. But if thou dost not know how to make this water, or hast it not in readiness, then poure upon it so much of the best, and most excellent balsome, and this will doe the same. Now, this blood is the balsome of balsomes, and is called the _Arcanum_ of blood, and it is so wonderful, and of such great vertue, that it is incredible to be spoken; wherefore thou shalt conceale it as a great secret in Physick. [Sidenote: How metalls may be preserved.] [Sidenote: What are the enemies of metalls.] In preserving of Metalls, their Enemies are first to bee known, that so much the better they may bee preserved from harme. The chiefest Enemies of Metalls are all sharp corroding Waters, all Corrosive things, all Salts, crude Sulphur, Antimony, and Mercury. But that you may know particularly how they show their enmity, it is thus. Sharp Waters, and such things as are Corrosive, and Salts shew their enmity, in that they mortifie, dissolve, calcine, corrupt Metalls, and reduce them to nothing. [Sidenote: How the fume of Sulphur doth discolour metalls.]
