the Vendee;—fragment of the meteoric stone which fell at 
Adare, in the county of Limerick, Ireland, in 1813;—frag¬ 
ment of one of those which fell Sept. 5th, 1814, at Agen, 
in the Pyrenees, and another of that which descended at 
Juvenas (Ardeche), on June 15th, 1821;—a portion of the 
meteorite which descended at Nanjenoy in Maryland, Fe¬ 
bruary 10th, 1825 ;—three of those that were seen to fall, 
October 13th, 1838, at Old Bokkeveld, at the Cape of 
Good Hope; and a fragment of that which fell in Missouri, 
February 13th. 1839 : (the former described in the Phi¬ 
losophical Transactions, the latter in the American Journal 
of Science for 1839.) 
Among the specimens of native copper (which presents 
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 lead in lava: to which is added 
a medal cast in the same lead which was ejected by Vesuvius 
in 1631. With these is also placed a specimen of artifi¬ 
cially produced metallic titanium , crystallized in cubes, 
from the smelting furnace of the great iron works at Mer¬ 
thyr Tydvil in Wales.— Native bismuth , massive, dis¬ 
seminated, and dendritic, in jasper, &c.: to which are add¬ 
ed, specimens exhibiting the artificial crystallization of the 
same, produced by the sudden cooling of the melted metal. 
Case 2. Native silver : among its varieties may be par¬ 
ticularized those exhibiting the various forms in which it 
most frequently occurs, such as tooth-shaped, wire-shaped, 
dendritical, moss-like, &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. — Native platinum , massive and as grains: rock 
specimens of the formation in which it occurs in the 
Ural, Siberia.— Palladium and osm-iridium , in a wrought 
state. 
Case 3. Native gold , subdivided into pure* and alloyed 
gold; the former chiefly massive, in detached crystals and 
as grains (from Bengal, Guinea, Sumatra, Brazil), and in
