Iron, Om. Slice 16 by 17 cm., weighing 1,280 grams. From a mass 

 weighing 421 kilograms, or 927 pounds, found about 1801 and first 

 described in 1843w An incomplete analysis by C. Bergemann yielded:

Stone, Cwa. Thirty-six nearly complete individuals weighing from 

 7 to 86 grams. One fragment with crust, weighing 325 grams, and 

 19 smaller fragments, weighing 430 grams. Aggregate weight, 1,607 

 grams. Fell February 3, 1882, at 4 o'clock in the afternoon. This fall 

 was one of the most remarkable on record, the number of fragments 

 being estimated as upward of 3,000, the aggregate weight of which 

 was from 174,113 grams to 300,000 grams, the largest known mass 

 weighing 70,000 grams. The stones were di^ributed over an area of 

 some 3 by .6 miles, according to Fletcher, or an area of 60 square kilo- 

 meters, according to Koch. The chemical composition of the stone, 

 according to Koch, is as follows;
