320 G. 0. Hoffmann — Souesite. 



Deducting the insoluble siliceous matter, and recalculating 

 the remaining constituents for one hundred parts, we obtain, 

 as representing the composition of the mineral : — 



Nickel... 76-48 



Iron 22-30 



Copper 1-22 



100-00 



There are only two instances on record of a mineral similar 

 to that above described having been met with. One of these 

 being the nickeliferous iron called "awaruite, " referred to by 

 W. Skey (Trans. K Zeal. Inst,, vol. 18, p. 401, 1885) as having 

 been found, associated with gold, platinum, cassiterite, chromite, 

 and magnetite, in the drift of the Gorge river, a stream flowing 

 into Awarua Bay, on the west coast of the South Island of New 

 Zealand ; and the other, the iron-nickel alloy described by A. 

 Sella (Compfc. Rend., vol. 112, p. 171, 1891) as occurring in the 

 auriferous sands of the Elvo, a mountain-stream, near Biella, 

 Piedmont, Italy. 



As tending to facilitate a comparison of these three, appar- 

 ently closely related, minerals with each other, their analyses 

 are here given in a tabular form, — (1) being the analysis of the 

 nickeliferous iron " awaruite" ; (2) that of the iron-nickel alloy 

 from the Elvo, Piedmont ; and (3) the analysis, after deducting 

 some insoluble siliceous matter and recalculating the remaining 

 constituents for one hundred parts, of the iron-nickel alloy from 

 the Fraser river, province of British Columbia.

The writer would suggest that this mineral be named 

 "souesite," after Mr. F. Soues — to whom he is indebted for 

 the sample sent for identification — to distinguish this find from 

 that of other naturally occurring iron-nickel alloys. 



* Nickel, with some cobalt.
