Equivalent to Sik. +8i,R, one atom of bronzite plus one atom 
of olivine, a form of silicate that we might expect to find in 
meteorites. 
(4) The nickeliferous iron.—As, already stated this iron is 
abundant in the meteorite, and sometimes in large nodules of 50 
to 100 grams; on a polished surface the Widmanstattian figures 
are beautifully developed by acid.. On analysis it was found 
to contain :

(5) Troilite—The proportion of troilite is not large, and it 
could be detached only in sma m 
constituents. I examined carefully for feldspar and schreiber- 
site; but the absence of both lime and alumina (except as a

ings of the mineral that might have been taken for schrei- 
ersite were found om examination in all instances to be
