contrary things and diuers operations, which before I tearmed the keyes of the Art. And _Aristotle_ saith, that the equalitie of the powers doth containe in it the action and passion of bodies. And this likewise is the opinion of _Auerroes_ reprouing _Galen_. It is thought that this is the most simple and pure medicine that may be found: It is good against the feauers and passions both of minde and bodyes, more cheape then any medicine whatsoeuer. He that writ these things shall haue the key that openeth, and no man shutteth, and when hee hath shut, no man is able to open it againe.

All other spelling and punctuation remains unchanged. The typesetting has used VV for W, with variable spacing. This has been replaced with W throughout. The sidenote in Chapter XVI of The Booke of the Secrets of Alchimie begins “The quantitie is called by the Logitians Passion,” it seems likely from the context that this should read The quality etc.
