the native nickel from Saxony, which was formerly 
classed with the ores of iron, under the denomina¬ 
tion of capillary pyrites ;—the arsenical nickel, 
called copper nickel;— nickel ochre, which is no 
oxide, but an arseniate, of nickel. Ores of bismuth: 
native bismuth, massive, disseminated and dendritic 
In jasper; to which is added a specimen exhibiting 
the artificial crystallization of the same, produced by 
sudden cooling of the melted metal;— sulphuret oj 
bismuth, the bismuth glance of Werner, with which 
is placed the Siberian needle ore of the same mine¬ 
ralogist, being a triple sulphuret of bismuth, lead, 
and copper.—Ores of uran; the protoxide of urani¬ 
um, called pitch ore, massive, pure, and w ith adher¬ 
ing ochre of the same metal;—the substance called 
uranite, or uran mica (which, according to Berze¬ 
lius, is no pure oxide of uran, buta uranate of lime) in 
groups of emerald-green and yellow' colours. The 
ores of tellurium or sylvane, w’hich are divided into 
native tellurium, white and yellow (containing gold 
and iron); the graphic ore so called on account of 
the disposition of its minute laminar crystals into 
groups that bear a distant resemblance to written 
characters; and the black or Nagyag 0 re (com¬ 
monly alloyed with gold and some lead).—Speci¬ 
mens of the oxide of chromium, in quartz, dis¬ 
covered by M. Leschevin at Creuzot, in the depart¬
