I 5 o THE HISTORY OF CHEMISTRY, 



fcribes the proccfs of rendering alkali of tartar 

 cauflic by means of lime ; and Lullius men- 

 tions its delumefcence. Ceberus takes fome 

 notice alfo of the Salt of Soda. Lullius fpeaks 

 of the production of Volatile Alkali. by putre- 

 fadion ; and we find in Valentfnus the method 

 of fcparating it from Sal Ammoniac, by the fix- 

 ed alkalies. Molt of the neutral fairs were 

 known to them. But they apprehended that 

 the Alkali vf. vitriohittun^ which they diftin- 

 guiilied by various names, retained always fomr 

 quality peculiar to the manner of its preparation. 

 The direcl union of Alkali of Tartar and Vitri- 

 olic acid is called by Crollius Tartarus vitriofa- 

 tt/s, while the fame fait, obtained by precipita- 

 tion with the Alkali of Tartar, from vitriolated 

 Iron, he denominates Speclficum purgans Parc\- 

 cclfl ; that procured by the detonation of Sul- 

 phur and Nitre, is the Nitrumfixum of Schroedcr ; 

 and what remains in the retort, after the diftilla- 

 tion of Aquafortis, is the common Panacea //&/- 

 Jlitica, the slrcanum duplicatum of Schroeder, 

 and the NitriiinvitriGlatum of Rolfirtckius. The 

 word Nitre, which formerly fignified the mine- 

 ral Alkali, was in this period applied to the At- 

 kali vcg. nitratum, and it Hills retains this figni- 

 fication. The sllkali vcjf. falitum, which Jac. 

 Sylvius, called Sal digc/livm, was alfo in their 

 lilt of neutral falts. Vitriolated mineral Alkali 

 received from its inventor, Glauber, tha name
