Cleavage, very indistinct traces parallel to the dode- 

 cahedron. Fracture conchoidal, uneven. Sur- 

 face smooth and shining. 



Lustre metallic. Colour silver-white. Streak un- 

 changed. 



Brittle ; it emits a grating noise when cut with a 

 knife. Hardness = 3-0 ... 3-5. Sp. Gr. = 13-755, 

 both observed in crystallised varieties. 



Compound Varieties. Massive: individuals scarce- 

 ly discernible, fracture conchoidal, uneven. 



OBSERVATIONS. 



1. Two kinds of native Amalgam have been distinguish, 

 ed, in reference to the solid or fluid state in which it is 

 found. The fluid varieties must be considered as solutions 

 of the solid ones in fluid Mercury. 



2. Dodecahedral Mercury consists of 

 Silver 36-00. 27-50. 

 Mercury 64-00. KLAPROTH. 72-50. CORDIER. 



Before the blowpipe the mercury is driven off, and we ob- 

 tain a globule of pure silver. 



3. The present species is always found in the repositories 

 of peritomous Ruby-blende. It is accompanied by other 

 ores of silver and mercury, and by hexahedral Iron-pyrites. 



4. It occurs at Moschellandsberg in the Palatinate, and 

 at Rosenau in Hungary ; it is said also to have been met 

 with in France, Spain and Sweden.
