THE BOND SPRINGS STONY METEORITE 
Plate XII. 
Microphotograplis by reflected light of sections etched with 
2 per cent, solution of picric acid in alcohol. 
Fig. 1. Two areas of taenite (white) associated with kamacite; the lower 
taenite grain has a dark core, presumably of minute carbon particles 
or dissolved phosphide. Etched for 10 seconds. Mag. 250. 
2. Two areas of taenite (white) associated with kamacite which is 
traversed by two sets of lamellae of an unidentified iron-nickel 
mineral. Etched for 20 seconds. Mag. 250. 
3. Eutectic intergrowth of taenite (white) and kamacite (dark), 
fringing an area of pyrrhotite (grey). Etched for 10 seconds. 
Mag. 750. 
4. Lamellae of unidentified iron-nickel mineral (white) in kamacite. 
Etched for 60 seconds. Mag. 350. 
5. Eutectic intergrowth of taenite (white) and pyrrhotite (grey). 
Unetched. Mag. 500. 
6. Eutectic intergrowth of taenite (white) and pyrrhotite (grey) 
fringing an area of pyrrhotite (grey). Etched for 10 seconds. 
Mag. 750.
