232 G. F. Kunz—WMeteorites from Kentucky and Mexico. 
flected light minute crystals of bronzite can easily be recog- 
nized, and analysis showed the presence of chromite in fine 
grains and a very small quantity of schreibersite. The analy- 
ses of the olivine and iron were kindly furnished by Mr. James 
B. Mackintosh of Lehigh University. The sample of the iron 
taken was selected, as he states, as carefully as possible, to 
ensure purity, but it was found impossible to free it entirely 
from earthy matter. The sample of olivine was also somewhat 
contaminated with foreign matter.

The balance in the last analysis is oxygen in the form of iron 
oxide, and undetermined constituents. For the pure metallic 
portion we obtain then A below, or B on the assumption that 
the deficiency in the analysis is ‘chiefly oxygen combined with 
iron as magnetic oxide.
