Iron, Og. Nearly 400 complete individuals, weighing from less 

 than 5 grams to 435,374 grams and of an aggregate weight of approxi- 

 mately 2,200 pounds or 998 kilograms ; also two etched slices, 34 by 22 

 cm. and 37 by 20 cm., showing large troilite nodules; a slice 18 by 12 

 cm., showing unusually large graphite nodules with veins of nickel 

 iron; and an etched slice 26 by 13 cm., weighing altogether 20,894 

 grams. (See pis. 12, 13, 14, and 17.) Aggregate weight of all found 

 not known, but nearly 5 tons, or 4,545 kilograms have been accounted 

 for. Date of fall unknown, but first iron found in 1891. Structure 

 coarsely octahedral. In addition to the nickel-iron constituent, O. A. 

 Derby found this iron to contain schreibersite, troilite, graphite, 

 cohenite, and rhabdite. Koenig and Huntington found microscopic 

 diamonds. (See No. 473.) Moissan showed it also to contain car- 

 borundum, while Mallet found small and variable amounts of plati- 

 num, iridium, and probably rhodium. An analysis by J. E. Whit- 

 field showed:
