May, 1902. Meteorite Studies, I Farrington. 



The analysis gave the following results: 



297 



The most striking feature of the composition revealed by this 

 analysis is the high percentage of Cr 2 3 . I know of no other 

 meteorite which shows so high a percentage, more than 1 per cent, 

 being rare. Most of this was found in the insoluble portion and may 

 hence be referred to chromite, especially as examination of sections 

 with the microscope shows a large quantity of the red translucent 

 grains which indicate that mineral. It may be worthy of remark, 

 however, that the chromium mineral of the meteorite was more easily 

 decomposed than ordinary chromite. Although left as an insoluble 

 residue ,after fusion with sodium carbonate, it went into solution on 

 treatment with sulphuric acid without requiring a separate fusion with 

 acid sulphate of potash. The percentage of Cr 2 O s noted in the 

 soluble portion of the meteorite may probably be regarded as a con- 

 stituent of the chrysolite, although its quantity here is above the 

 average. 



The quantity of A1. 2 3 , shown in the soluble portion of the 

 above analysis, is unusually high and is difficult to account for.
