NATURAL HISTORY. 
[long 
tion, is that of the Baron Berzelius, founded upon the 
electro-chemical theory and the doctrine of definite pro¬ 
portions, as developed by him in a memoir read before the 
Royal Academy of Sciences at Stockholm, in 1824. The 
detail of this arrangement cannot here be entered into: 
it is, however, partly supplied by the running titles at the 
outsides of the glass Cases, and by the labels within them. 
The first two Cases, and part of the third, contain the 
electro-positive native metals: iron, copper, bismuth, lead, 
silver, mercury, palladium, platinum, osmium and gold. 
Case 1. Of native iron , found in insulated masses, and 
disseminated in meteoric stones, the following specimens 
are deposited native iron from Gross-Kamsdorf in Sax¬ 
ony ;—two small polished pieces of the mass found in 
Southern Africa, which weighed about 250 pounds, and is 
now in the cabinet of Haarlem;—fragment of the iron 
from Senegal;—specimens of the native iron from O turn pa, 
in the Gran Chaco Gualamba, in South America, described 
by Don Rubin de Celis, who estimated the weight of the 
mass to be about 300 quintals, or 15 tons *; —a large piece 
detached from the celebrated mass of Siberian native iron, 
which was discovered by Pallas on the summit of a hill be¬ 
tween Abakansk and Belskoi Ostrog on the banks of the 
Jenisey, where it was considered by the Tartars as a sacred 
relic: the mass originally weighed about 1680 pounds ;— 
a mass of iron from Atacama, resembling that of Siberia, 
and also containing much of the olivine-like substance 
within its cells;—a piece of the large mass from Ellen- 
bogen, in Bohemia, and another of that found on the Col- 
lina di Brianza, in the Milanese;—two specimens of the 
mass of iron found at Lenarto in Hungary, one of which 
(being polished and treated with acid) exhibits the outlines 
of imperfect crystals ;—a small piece of the large mass in 
the Capitania di Bahia, Brazil;—another, from that found 
in the province of Durango, Mexico;—a specimen detached 
from the large mass of iron preserved at Aix-la-Chapelle; 
—an Esquimaux knife and harpoon (from Davis’s Straits, 
Lat. 76° N. Long. 66° W.), the iron of which is meteoric; 
* The large mass of iron placed against the wall under the window in 
the N. E. compartment, was sent from Buenos Ayres, bv Sir Woodbine 
Parish; it is supposed to be part of that of Oturnpa : its weight 1400 
pounds.
