1567 GLAUBER (Johann Rudolph) Tractatus de Natura Salium, sive dilucida descriptio, 

 perfecta explanatione declarans Naturam, Proprietates, et Usus Salium vulgo Notorum, 

 ut et alius cujnsdam, admodum mirabilis, et haetenus mundo ignoti salis .... sine ponderum 

 suorum diminutione, et formariim mutatione in dura, et incombustibilia corpora transmutari 

 possint, etc. etc. etc., 12mo. sewn {rare), \2s Qd Amst, J. Jansson, 1659 



This important treatise first describes 'Glauber's Salt' (Sodii Svlphas, 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, 



1568 Tractatus de Signatura Salium, Metallorum, et Planetarum, sive Funda-

 supputari queant, 12mo. sew7i, Ss ib., a. e., 1659

' Glauber a de plus repandu de la lumiere sur I'histoire de quelques autres sels, tels que le sulfate et le nitrate d'ammon- 

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

 huiU 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 que Ton p^ourrait le faire aujourd'- 

 hui, plnsieurs operations tout a fait inconnues a son epoque ... II a donn^ plusieurs procedes ingenieux pour la 

 fabrication des pierres gemmes artiticiellcs. On peut faire remonter a lui I'invention des bains de vapeur par encaissement. 

 II a fait connaitre les proprietes de I'acide tire de la destination da bois, indiqne la maniere de preparer des boissons 

 vineuses avec les fruits sees et de faire de I'eau -de-vie ou de vinaigre avec du marc de Ta.\sin.' - Bincjr. Gen. He was the 

 first to procure hydrochloric acid while experimenting with sulphuric acid and common salt, and probably thti-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, Avhich is still distinguished by his 

 name as Glauhcfs 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 ot mercuric chloride and antimony trisulphide upon one another. '—Pro/. E. v. Meyer.
