Miguel Rubin de Celis in 1783. Weight 30,000 Ibs. A mass 
weighing 1400 Ibs. in the British Museum is believed to be from 
the same locality. This mass was covered with a crust of oxyds 
four to six inches thick, on the under side. It has cavities of va- 
rious sizes, which are more or less filled with magnetic-pyrites. 
Structure highly crystalline, and when etched presents surfaces 
resembling erystalline masses of antimony and bismuth. It is 
very malleable. G.=7:54-7-6, Rumler. Analysis by Howard.

18. Senegal, the Upper Senegal, Africa. Made known by 
Compaguon in 1717. Vast quantities are said to be scattered 
over the countries in the Bumbuk and Siratik countries, several 
et of which have been brought by the negroes to Fort St. 
wis at the mouth of the Senegal. Compact, with a very 
slight admixture of magnetic pyrites. By etching, short raised 
lines appear, which are parallel or intersect each other at varions 
angles presenting like the ‘Tucuman iron, a striped or plumous 
appearance. When deeply etched the surface becomes granular.

_ 19. Cape of Good Hope, between Sunday and Boschesman’s 
tivers, Cape Colony, Africa. Discovered in 1793. Described by 
arrow in 1801, and by van Marum in 1804. The original mass 
Weighed over 300 lbs., of which 171 Ibs. are now in the cab- 
inet of Natural History at Haarlem in Holland. : Capt. Alexan- 
discovered in 1837 great numbers of metallic masses, sup- 
to be meteoric, over a large extent of country along the 
Great Fish River in Cape Colony, which are supposed to belong 
to the same fall with the above. Compact, with a small quantity 
of finely divided magnetic pyrites. When etched exhibits no 
Wa maunstittian figures. G.=663-7'94, Rumler. Analysis by 
ehrle.

20. Lenarto, Hungary. Found in 1814. Weight 194 Ibs., 
(Austrian,) of which 134 are now in the National Museum at 
Pesth. It possessed an irregular, tabular form, and was highly 
crystalline. It was covered with a crust of dark brown metallic 
oxyds, and contained three empty cavities. It contains magnetic
