﻿G. F. Kunz — Meteoric Iron from New Mexico. 313 



The large plate (VII) is an exact reproduction of the largest 

 section of mass No. 1. It was made after several experimental 

 attempts by a new process devised by the writer (see A. A. A. 

 S. Rep., 1886). The whole of the iron was sunk into wax, 

 except the surface to be reproduced ; this was dusted with 

 graphite, and the copper thrown down on this, producing what 

 is termed a negative electrotype; this, when the unevenness is 

 removed, prints an exact facsimile of the Widmanstattian 

 figures, more accurately and at only one-sixth to one-eighth the 

 cost of any other process. This is the largest etched surface 

 that has ever been faithfully reproduced. 



I was kindly informed by Dr. Whitman Cross, of Denver, 

 Col., that on Oct. 6, 1884, a meteorite was presented to the Col- 

 orado Scientific Society with descriptive remarks by Mr. 

 Richard Pearce of the Boston and Colorado Silver Mining Co. 

 It was sent to the company from Albuquerque, 1ST. M., as silver 

 bullion, — and could not be traced further back, — although it 

 was probably found in the vicinity of the place from which it 

 was forwarded. Its weight before cutting was about 2'5 kilo- 

 grams, and its dimensions were 48 X80xl00 mm . A short paper 

 upon this meteorite was read before the Colorado Scientific 

 Society on June 1, 1885, by Mr. L. Gr. Eakins of the Geolog- 

 ical Survey, This paper contains an analysis of the iron, 

 which is subjoined : 



Fe 88-760* 



Ni 9-860 



Co 0-510 



Cu 0-034 



Zn 0-030 



Cr trace 



Mn 



C 0-410 



P 0-182 



S 0-012 



Si 0-044 



99-842 



This paper by Mr. Eakins appeared in the Proceedings of Col. 

 Sci. Soc. for 1885 and these figures were kindly furnished by 

 him. The striking similarity between this analysis and that of 

 the Grlorieta meteorite leads me to believe that this iron is the 

 seventh fragment of the Glorieta meteorite, which was found 

 by the Mexican, and that he mistook it for silver bullion and 

 sold it as such. ,
