The mineral composition as calculated from analyses is : 



Per cent. 

 Nickel-iron 98. 317 



Sclireibersite . 1. 06 



Troilite . 05 



Chromite Trace 



Secondary iron oxide (Fe^Os) Trace 



99. 427 



The structure is octahedral, with fine plates of taenite. In com- 

 position and structure it so closely resembles the Carlton-Hamilton 

 iron as to lead to the suggestion by Merrill that it may belong to 

 the same fall.

Iron, Om. A 70-gram end slice, triangular in outline, showing por- 

 tion of original surface, from a mass weighing 298 kilograms (657 

 pounds) found about 1885. Analyses by Dr. J. Fahrenhorst yielded 

 the results given below. No. I being the total composition and II that 

 of the metal minus the sclireibersite, troilite, and lawrencite:
