G. F. Kunz — New American Meteorites. 



319 



The meteorite is a typical chondrite, apparently of the type 

 of the Parnallite group of Meunier, which fell February 28, 

 1857, at Parnallee, India. The stone is porous, and when it is 

 placed in water to ascertain its specific gravity, there is a con- 

 siderable ebullition of air. The specific gravity, on a fifteen- 

 gram piece, was found to be 3 # 638. The crust is rather thin, 

 opaque black, not shining, and, under the microscope, is very 

 scorious, resembling the Knyahinya, Hungary, and the West 

 Liberty, Iowa, meteoric stones. A broken surface shows the 

 interior color to be gray, spotted with brown, black and white, 

 containing small specks of meteoric iron, from one to two 

 millimeters across. Troilite is also present in small rounded 

 masses of about the same size. On one broken surface was a 

 very thin scum of black substance, evidently graphite, soft 

 enough to mark white paper; a feldspar (anorthite) was like- 

 wise observed, and enstatite was also present.

The approximate composition of the mass was got by ex- 

 tracting everything possible by an electro-magnet, which took 

 out all the nickel iron and a little troilite, leaving the siliceous 

 part and most of the troilite. Then the amount of S present 

 in the magnetic portion, and that in the siliceous portion, was 

 calculated as FeS; the silicates were split into two portions by
