‎---- PREMIERE EDITION FRANCAISE ------ BEL EXEMPLAIRE ------ "One of the outstanding chemists of the eighteenth century". (Partington II pp. 662/678) ------ "STAHL was the originator of the phlogiston theory, which dominated chemistry until the end of the eighteenth century. He took the structure of his theory from Becher... STAHL elaborated from Becher's "second earth" a new chemical principle, phlogiston, a substance representing the principle of combustibility that combined with other chemical substances to form compounds... The flaws in the phlogiston theory are obvious and it did not survive the eighteenth century ; however, it served as an important link between the older chemical concepts and the new, an attempt to modify the existing intellectual framework in order to account for new experimental observations" ------ "By observation and experiments the author concluded that salts are an earth combined with water. STAHL also furnished details on the various combinations of salts, the accompanying phenomena and their causes". (Cole N° 1247) ---- DSB XII - Duveen 561 - Ferguson II 397**4877/ARM2A‎
