CLASS V. LITHOHALOIDES.— Insoluble in water, for the most 

 part colourless, and chiefly of a habitus partaking of the nature of salts ; 

 in their chemical constitution, essentially oxygen salts and haloide salts, 

 with won-metallic radicals of the predominating base, acid, or both ; but 

 still with the exception of all silicates and aluminates, and all combina^ 

 tions of titanic and tantalic acids. 



Order I. Anhydrous Lithohaloides. 



* The mendipite might probably be more correctly placed among the metallic 

 oxides.
