ash gray, granular, compact. Structure chondritic. Original fall 

 over 1,000 stones, weighing upward of 500 kilograms, or 1,100 pounds. 

 This is one of the most interesting of stony meteorites owing to the 

 very full data compiled by Haidinger regarding its fall, as well as on 

 account of the number of stones. It was studied in thin sections by 

 Kenngott in 1869, who recognized the presence of enstatite, olivine, 

 troilite, and native iron. These results have since been confirmed by 

 Wadsworth. Analysis (recalculated from Baumhauer) yielded :

It was in this meteorite that Dr. Otto Hahn thought to have dis- 

 covered fossil remains of sponges, corals, and crinoids. The fall is 

 of further interest from the fact that it included one of the largest 

 stone meteorites known, a mass weighing 294 kilograms (047 pounds), 

 which is now preserved in the Vienna Museum.

Stony-iron, Pallasite. Rough fragment, a coarse mesh of iron with 

 included olivines, weighing 287 grams. The fragment repre^sents his- 

 torically one of the most interesting meteorites. It was found by a 

 Cossack in 1749 on the surface of the highest point of a lofty mountain 

 between Krasnojarsk and Abakansk in Siberia, where it was regarded 

 by the natives as a holy thing fallen from heaven. It was first made 

 Imown to the scientific world by the explorer Pallas in 1772. The 

 original mass weighed about 1,500 pounds, the largest portion of 

 which is in the museum at St. Petersburg. It has been the subject of 

 numerous investigations. The olivine presents a perfection of crystal
