H. A. Ward — Veramin Meteorite. 459 



meteorites now on display (on deposit) in the Geological Hall 

 of the American Museum of Natural History in New York. 



As to the composition of Veramin I give here the results of 

 a careful analysis made for me by Prof. J. Edward Whitfield 

 of Philadelphia. 



The specific gravity of the stone as received was 4*57. 



On separation the stone was found to be made up of 42'3 per 

 cent mineral and 57*7 per cent metal, although the portion 

 separated as mineral contains some iron oxide, which originally 

 must have been metal. Of the metallic portion the specific 

 gravity is 5*56, rather a low figure for metal of this composi- 

 tion. 



It was extremely difficult to entirely separate the mineral 

 matter from the metal; although the small particles were ham- 

 mered until about the thickness of tissue paper, there was an 

 amount of insoluble remaining with it amounting to 9*28 per 

 cent, this of course including any silicon of the metal as silica. 



The analysis of the metallic portion, excluding all the insol- 

 uble as mineral matter, is as follows : 



Iron _ . 92-06 per cent 



Nickel 6-96 " 



Cobalt 0*73 " 



Phosphorus. 0*10 " 



Sulphur 0-15 " 



It was impossible to obtain even a trace of carbon with 

 the small amount of material at hand, and whether or not the 

 metal contains silicon, I cannot say on account of the diffi- 

 culty of obtaining the metal free from mineral matter. The 

 analysis was made on an amount approximating four grams, 

 any other determinations being impossible for want of material.
