MINGAYE: IRON METEORITE FROM YENBERRIE 315 



and 3320 grams. Before being forwarded a portion of the 

 mass was removed for analysis. 



Clean turnings from the facing machine, representing the 

 metalHc portions only, were analyzed with the results given in 

 table I.

 Sp. gr. (average of two determinations), 7.304. 

 "100 grams of the iron gave 0.00026 gram of platinum. This is the first reported 

 case of platinum in an Australian meteorite. No tin nor gold could be detected. 

 Partial duplicate determinations gave: Ni + Co, 7.46; P, 0.195; C, 0.065. 



From a dark nodule in the center of the meteorite were found 

 pieces of metal coated with a black brittle substance which 

 yielded the analysis given in table 2, after the metallic portions 

 had been removed so far as possible.
