such as dendritic, filiform, &c.) may be specified the 
mass from Hudson’s Bay, found by Mr. Hearne, and 
described by him in his journal.— Native bismuth, mas¬ 
sive, disseminated, and dendritic, in jasper, &c.; to which 
are added, specimens exhibiting the artificial crystalliza¬ 
tion of the same, produced by the sudden cooling of 
the melted metal.— Native lead in lava.—Among the 
varieties of native silver, may be particularized those 
exhibiting the various forms in which it occurs, such 
as tooth-shaped, wire-shaped, dendritical, mosslike, &c., 
many of which are aggregations of minute crystals. 
Case 3. Native mercury, and hydrarguret of silver 
or native amalgam; the latter crystallized in perfect 
and modified rhombic dodecahedrons, globular, &c.— 
Native gold, subdivided into pure and alloyed gold; 
the former chiefly massive, as grains (from Bengal, 
Guinea, Sumatra), and in brown iron stone, in quartz, 
with needle ore, &c. from Siberia ; the alloyed gold 
(principally from Transylvania) crystallized in minute 
cubes and octahedrons variously aggregated, in reti¬ 
cular plates, &c. With these are placed a few speci¬ 
mens of the alloys known by the names of electrum and 
auriferous silver .— Native tellurium /—and tellurets, or 
its combinations with bismuth (considered by Esmark as 
native tellurium), with lead, with silver and lead, with 
silver and gold (being the foliated, the white and yellow, 
and the graphic tellurium of authors).— Native antimony 
from Dauphine, and antimonialsilver or stibiuret of silver. 
Case 4. Native arsenic (formerly called testaceous 
cobalt) in reniform and botryoidal shapes, from Andreas- 
berg, &c., and its chemical combinations: with nickel 
(commonly called copper-nickel); with cobalt , com¬ 
prising the grey and part of the white cobalt of some 
mineralogists; with bismuth , in small hair-brown glo¬ 
bules from Schneeberg in Saxony.—The remainder of 
this case contains the substances belonging to the con¬ 
fined orders of Carbon and of Selenium . To the former 
are referred the diamond, anthracite, graphite; to the 
latter the selenium metals or seleniurets. Among the
