PHYSIOGRAPHY. 33 



Mellite. 



3. It is found at Beresofsk in the Ural, accompanied by Red Lead- 

 Ore, Pyromorphite, Vauquelinite and Galena. 



MELILITE. 



Primary form. Right square prism. 



Secondary form. The primary, with its lateral edges trunca- 

 ted. Fracture imperfectly conchoidal. 



Color yellow, inclining to red or green. Opake. 

 Hardness = 5-5 ... 6-0. Sp. gr. = 3-041. 



1. Before the blow-pipe, it melts, without ebullition, into a greenish 

 glass. Reduced to powder, it gelatinizes with nitric acid. 



2. Analysis. 



By CARPI. 



Silica 38-00 



Lime - - - 19-60 



Magnesia .-.... 19*40 



Alumina 0-90 



Oxide of iron 12-10 



Oxide of titanium ..... 4-00 



Oxide of manganese ----- 2'00 



3. It is found at Capo di Bove, and Tivoli near Rome, accompanied 

 by Nephiline, in the fissures of a volcanic rock. 



4. It will probably prove, if its hardness and specific gravity can be 

 relied upon, to be a new species. 



MELLITE. Pyramidal Melichrone-Resin. 

 MOHS. 



Primary form. Octahedron with a square base. P on 

 P =93. 



Secondary forms. 



J. Primary, with the summits truncated. 



2. The same, with the truncation of the angles of the 

 base. 



3. The same as 2, with the truncation of the upper edges 

 of the octahedron.
