are deposited, as appendix to the ores of iron, the 
substances called aerolithes^ because they have

Saxony;—two small polished pieces of the mass 
found in Southern Africa, which weighed about

—fragment of the iron from Senegal:—specimens 
of the native iron from Otumpa, 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 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
