The most striking feature of the composition revealed by this 
analysis is the high percentage of Cr,O,. 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,O, 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 Al,O,, shown in the soluble portion of the 
above analysis, is unusually high and is difficult to account for,
