 perfecta explanatione declarans NATURAL, PROPRIETATES, et Usus SALIUM VULGO NOTORUM, 

 ut et alius cujusdam, admodum mirabilis, et hacterms mundo ignoti salis .... sine pondernm

 possint, etc. etc. etc., 12mo. sewn (rare), 12s 6d Amst., J. Jartsson, 1659 



This important treatise first describes 'Glauber's Salt' (Sodii Sulpha?, B.P.), which he. obtained by the action of 

 sulphuric acid on common salt, the discovery by which the author's name is best known.

' Glauber a de plus repandu de la lumiere sur 1'histoire de quelques autres sels, telsquelesulfate et le nitrate d'ammon- 

 iaque, le nitrate de potasse employ^ dans la teinture, etc. II parait avoir entrevu le premier 1'existence du chlor. II 1'appelle 

 huile ou esprit de sel rectifie, et soutient qu'on peut en faire un excellent usage en medicine, etc. II demontra avec sagacite 

 les phenomenes de composition et de decomposition des corps, et il expliqua, aussi bien qr.e Ton pourrait le faire aujourd'- 

 hui, plusieurs operations tout a fait inconnues a son epoque ... II a donne' plusieurs precedes ingemeux pour la 

 fabrication des pierres gemmes artih'cielles. On pent faire remonter a lui 1'invention des bains de vapeur par encaissement. 

 II a fait connaitre les proprietes de 1'acide tire de la destination du bois, indique la maniere de preparer des boissons 

 vineuses avec les fruits sees et de faire de l'eau-de-vie ou de vinaigre avec du marc de raisin. ' -Einqr. Gen. He was the 

 first to procure hydrochloric acid while experimenting with sulphuric acid and common salt, and probably the first to 

 obtain nitric acid by the action of sulphuric acid on nitre. He discovered the chlorides of zinc, copper, tin, and arsenic, 

 and numerous other important chemical preparations, including sulphate of sodium, which is still distinguished by his 

 name as Glauber's Salt. 



' In theoretical points he gave proof of his clear-sightedness, explaining, for example, many of the effects of chemical 

 affinity in the decomposition of salts by acids and bases, etc. He was the first to explain a case of what we call double 

 decomposition the mutual action of mercuric chloride and antimony trisulphide upon one another.' Prof. E. v. Meyer.
