substance from Siberia, also called emerald copper, 
on account of its pure green colour; and the 
A^ery scarce sky blue velvet copper ore. — Phos¬ 
phate of copper from Nassau and Hungary.— Mu¬ 
riate of copper^ crystallized and laminar: to 
which also belongs what is called green sand of 
Peru, or atacamite, from being found in the desert 
of Atacama, between Chili and Peru, as sand of a 
small river. The rest of this case is occupied by 
the principal varieties of the different arseniates of 
copper^ namely, the foliated arseniate, or copper 
mica, the lenticular arseniate, or lentil ore, and the 
olive ore of Werner, which are formed into five 
distinct species by some mineralogists; to which 
is added a specimen of the martial arseniate of 
copper. (A greater variety of arseniates of copper 
Avill be found in the collection of British minerals : 
Cornwall.) 
{Case 36.) contains ores of iron, viz. native 
iron, arsenical pyrites (also called arsenical iron, and 
mispickle' a variety of which is argentiferous,) and 
common iron pyrites, with its various crystalline 
modifications derived from the cube, which is either 
smooth or striated. The most interesting speci-* 
mens deposited in this case are those of native iron, 
and the stones called aerolites' because they have 
fallen from the atmosphere, or meteoric stones, be¬ 
cause they are by some supposed to be depositions 
from meteors. The specimens of the former are,
