Nat. Hist. 
of the meteoric stone which fell at Adare, in the county 
of Limerick, Ireland, in 1813;—fragment of one of those 
which fell Sept. 5th, 1814, at Agen, in the Pyrenees, 
and another of that which descended at Juvenas (Ar- 
deche), on June 15th, 1821. 
Among the specimens of native copper, (which pre¬ 
sents a great variety of forms besides the crystallized, 
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; to which is added 
a medal cast in lead ejected by Vesuvius in 1631. 
Case 2. Native silver; * among its varieties may be 
particularized those exhibiting the various forms in 
which it most frequently occurs, such as tooth-shaped, 
wire-shaped, dendritical, mosslike, &c., many of which 
are aggregations of minute crystals.— Native mercury, 
and hydrarguret of silver or native amalgam; the 
former chiefly as globules, disseminated in cinnabar, 
sparry limestone, &c.; the latter crystallized in perfect 
and modified rhombic dodecahedrons, globular, &c.; 
to which are added figures and ornaments moulded and 
modelled in amalgam, by the miners of Mexico. 
Case 3. Native gold, subdivided into pure and al¬ 
loyed gold; the former chiefly massive, in detached 
crystals and as grains (from Bengal, Guinea, Sumatra, 
Brasil), 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 retieular plates, 
&c. With these are placed a few specimens of the 
alloys knowm by the names of auriferous silver and 
electrum.—Native platinum, massive and as grains: rock 
specimens of the formation in which it occurs in the Ural, 
Siberia.— Osm-iridium, in a wrought state. 
In this Case begin (continued to Case 12) the electro¬
