teresting specimens deposited in this case are 
those of native iron, and the stones called aero¬ 
lites, because they have fallen from the atmos¬ 
phere, or meteoric stones , because they are by 
some supposed to be depositions from meteors. 
The specimens of the former are ,—native iron 
from Gross-kamsdorf, in Saxony;—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 na¬ 
tive iron from Otumpa, in the Gran Chaco Gua- 
lamba, 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 between 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 1,680 
pounds a piece of the large mass from Ellenbo- 
gen, in Bohemia, and another of that found on 
Collina di Brianza, in Milan, which has been describ¬ 
ed by Chladni and analyzed by Gehlen. Of meteoric 
stones (classed with native iron, because they all 
contain this metal, alloyed with nickle) the follow¬ 
ing are placed in chronological order ;—two small 
fragments of the stone which fell at Ensisheim, in 
Alsace, Nov. 7th, 1492, in the presence of the 
emperor
