SALOON. 
Nat. Hist, 
hand side of the principal entry from the first 
room into the Saloon, are deposited the metallic 
ores. 
(Case 29.) The ores of platina, gold and 
mercury. — Platina in grains from Peru and 
Brazil: the latter mixed with grains of greyish 
yellow gold.—Native gold, subdivided into pure 
and brass yellow gold: the former chiefly mas¬ 
sive and as grains (from Guinea, Bengal, Suma¬ 
tra, Ireland, &c.) and in brown iron stone, in 
quartz, with needle ore (acicular sulphuret of 
bismuth, &c.) from Siberia; the brass yellow 
gold (principally from Transylvania) crystallized 
in minute cubes and octohedrons variously aggre¬ 
gated, in reticular plates, &c. — The ores of 
mercury in this case are:—the sulphurets, con¬ 
sisting of dark red cinnabar (by far the more 
common variety) massive, crystallized, and in 
combination with various mineral substances ; the 
bright red cinnabar (native Vermillion, much es¬ 
teemed by painters) 5 the hepatic mercurial ore, 
from Idria, compact and slaty : the former also 
with petrifactions (coral-ore) ; corneous mercury 
(muriate of mercury) with native quicksilver, &c. 
(Case 30 .) This case contains (besides some 
additional specimens of gold and mercurial ores, 
among the latter of which is the scarce native 
amalgam, crystallized and globular) the ores of 
silver.
