12 Notice of Prof. Clark's Thesis on Metallic Meteorites. 
12. Bohumilitz. Found in 1829. Described in 1830. Weight 
103 lbs. Preserved in the National Museum at Prague. Was 
covered with a thick crust of limonite. It is composed of a me- 
tallic mass, a large quantity of magnetic pyrites and an unknown 
substance, which is black, not very hard and not graphite. 
black mineral occurs in the interior as well as at the surface of 
the mass, sometimes in portions nearly an inch in length, and is 
intimately mixed with finely divided metal and pyrites. These ~ 
black masses are enclosed in a coating of magnetic pyrites. Anal- 
ysis by Berzelius. .

Berzelius dissolved 60 grammes of filings from the mass in 
nitric acid, and found, of insoluble carbonaceous matter, 0°672 
grammes, and of crystalline magnetic scales, 0-777 grammes. 
The first contained carbon, alumina, silica, iron, nickel, phosphate 
and chromate of iron. The second consisted of

This is the substance which is now regarded as a phosphuret 
of iron and nickel called Schreibersite by Patera, after von 
Schreibers.* : 
13. Bahia, Brazil, 10° 30/ 8. lat., 33° 15’ W. long. from San 
Salvador. Discovered by Bernardus da Mota Botelho in 1784. 
Described by A. F. Mornay in 1816. ‘This mass was seven feet 
long, four wide and two thick, and weighed 17,300 Ibs. Ex- 
hibits imperfect Widmannstattian figures and contains small 
quantities of magnetic pyrites. Analysis by Wollaston.

Tenn. According to Prof. Wohler, the specimens of this mete- 
orite bear a striking resemblance to those of the mass from Szla-
