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, February 
10th, 1825;—fragment of the Tenessee meteorite, May 9th, 1827 ;— 
loose grains of that of Chesterfield, Virginia, June 4th, 1828;—a 
meteorite, weighing about four pounds, which fell at the village of 
Akburpoor, in the district of Saharanpore, April 18th, 1838, presented 
by Capt. Cautley, Bengal Artillery;—a fragment detached from one of 
the three stones which, on June 6, 1838, simultaneously fell at three 
villages about a mile distant from each other in the valley of Berar 
(situated Lat. 21° N. Long. 77° 20' E.) in the East Indies;—three 
of those that were seen to fall, October 13th of the same year, 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 
Philosophical Transactions, the latter in the American Journal of Science 
for 1839);—two large portions of those that fell, June 12th, 1841, at 
Triguerre, Canton of Chateau-Renard, department of the Loire. 
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,) and that from the mountains sepa¬ 
rating the Quananger and Alten Fiords in the north of Norway.— Native 
lead , in lava : to which is added a medal cast in the same lead which was 
ejected by Vesuvius in 1631.— Native bismuth , massive, disseminated, 
and dendritic, in jasper, &c. : to which are added, specimens exhibiting 
the artificial crystallization of the same, produced by the sudden cooling 
of the melted metal. — In this case is also placed a specimen of arti¬ 
ficially produced titanium , crystallized in cubes, from the smelting 
furnace of the great iron works at Merthyr Tvdvil in Wales. 
Case 2. Native silver : among its varieties may be particularized 
those exhibiting the various forms in w 7 hich it most frequently occurs, 
such as tooth-shaped, moss-like, wire-shaped, dendritical, branched, den¬ 
ticular, massive, &c., particularly from Kongsberg and the Hartz (the 
latter presented by His Majesty George IV.), many of which are aggre¬ 
gations of minute crystals.— Native mercury, and hydrarguret of silver 
or native amalgam; the former chiefly as globules, disseminated in cin¬ 
nabar, sparry limestone, &c. ; the latter crystallized in perfect and mo¬ 
dified rhombic dodecahedrons, globular, &c. : to which are added some 
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 the al¬ 
luvial deposits of Guinea, Sumatra, Bengal, Brazil, Leadhills in Scot¬ 
land, &c.), and in brown iron-stone, in quartz, with needle-ore, kc., 
from Siberia; the alloyed gold (principally from Transylvania) crystal¬ 
lized in minute cubes and octahedrons variously aggregated, in reticular 
plates, &c. With these are placed a few specimens of the alloys known 
by the names of electrum: the electrum of Smeof or Schlangenberg, 
in Siberia, contains one-third of silver. 
In this Table Case begin (continued to Case 12) the electro-negative
