G. P. Merrill — Meteoric Iron from Texas. 337 



sobetanaptliol method on a 200 cc. portion of the solution 

 (2.6716 gms.). Its identity was thoroughly established. 



Sulphur was determined on a second portion of the iron . 



weighing 13.4440 grams. This was dissolved in nitric 

 acid, the sulphur separating in part as such in visible 

 floating particles. This was oxidized with fuming nitric 

 acid and determined as barium sulphate.'' The results 

 of the analysis are as follows : 



Iron 90.69 j 



Nickel 7.25 



Cobalt 74 



Copper 02 



Platinum none 



Chromium trace 



Manganese none 



Carbon 35 



Phosphorus 23 



Sulphur 03 



Total 99.31 



These figures fall well within the limits of other anal- 

 yses of iron of the coarse octahedrite group and need 

 little comment. The small amount of material available 

 for analyses is probably the cause of the apparent absence 

 of platinum.
