Prof. Naumann on Mineralogical Classification. 41 



t^ytwpsis of the Spccki- arranged according to the Classes and their 

 subordinate divisions. 



CLASS I. OXIDE OF HYDROGEN.— Water and ice are such pecu- 

 liar members of the mineral kingdom, that they must necessarily be 

 separated from all otlier minerals, and be placed in an independent class, 

 Water. Ice. 



CLASS II. HYDROLITES.— Acids, oxygen-salts and haloide- 

 salts with earthg or alkaline bases, which are either wholly, or in a great 

 measure, soluble in water, and hence impart a distinct taste to the tongue. 



Order I. Hydrous Hydrolites. — Sassoline (Boracic acid), Tinkal 

 (Borax), Trona, Urao, Natron, Glauber salt, Mascagnine, Ammonia- 

 alum, Potash-alum, Soda-alum, Hair-salt, Epsom-salt, Polyhalite, Lime- 

 saltpetre. 



Order II. Anhydrous Hydrolites. — Potash-saltpetre, Soda-salt- 

 petre, Sal-ammoniac, Rock-salt, Sulphate of potash, Thenardite, Glau- 

 berite. 



CLASS III. CHALCOHYDROLITES.— Acids, oxygen salts and 

 haloide-salts with metallic radicals of the bases or acids, which are wholly, 

 or in a great measure, soluble in water, and impart a distinct taste to the 

 tongue. 



Order I. Anhydrous Chalcohydrolites. — Arsenious acid. 



Order II. Hydrous Chalcohydrolites. — Coquimbite, Basic 

 sulphate of iron, Botryogene, Iron-vitriol, Copper-vitriol, Cobalt-vitriol, 

 Zinc- vitriol. 



CLASS IV. CHALCOHALOIDES.— Insoluble in water, for the most 

 part coloured, and chiefly partaking of a saline habitus ; in chemical con- 

 stitution they present themselves as oxygen salts and haloide salts with 

 metallic radicals of the prevailing bases or acids (or also of both) ; but all 

 silicates and aluminates, and all titanic acid and tantalic acid combina- 

 tions, are excepted.
