 The third German edition of the author's complete works. 'He regarded salt, sulpliur, and im rcury, as the three 

 bodies contained in the metals, and inferred that the pliilosoplicr's stone must hr a sut ut' conibiuaLion— a compound, 

 namely, of salt, sulphur, and mercury ; so pure that its i>rojection on the baser metals should be able to work them up 

 into greater and greater purity, bringing them at last to tlie state of silver and gold. His practical knowledge was great ; 

 he knew how to precipitate iron from solution by polish, and was acquainted with many similar processes, so that ho is 

 ranke<l as the founder of analytical chemistry.'

 of antimony trichloride, of powder of algaroth (basic chloride of antimony), of antimony trioxide, and of potassic

 The tirstcdition of this curious work is excessively liAi.i;. mi ((jpy Iia\ iii;^ liajijc ned for sale for the la.st 20years. Sonic 

 of the experiments described and deincted are very cnirious, including instructions how to make Weather-gla.s.ses ; 

 Water-clocks, etc , E.Kperiments of ' drawing water by the Crane, and by Engins, of forcins water by ayre compressed and 

 by Engin.s, of producing sounds by ayre and water, by evaporarion of water by lire, and by Engins, of motions by 

 evaporating water, and by rarifying ayre,' etc. etc. etc. Bearing in mind the early dato of publication, its descriptions of 

 engines driven by steam are of considerable interest. There is no copy of this edition in the British Museum, nor is the 

 author noticed in D. N. B. 



Page 155 describes how to make a freezing mixture, which is of special interest, Robert Bovle having been 

 crt'ditf I with making the first experiments in 1667— thirtv-thr.^e years after the publication of the above work.
