then ground flat and polished, and the structure was then very clearly 
seen (Fig. 5). 
Here the masses of nickel iron stand out sharply from the ground 
mass, their shapes being well represented by those in the centre of the 
Fig. These masses could be dug out with some difficulty and then 
appeared to be tough malleable particles, having all the physical pro- 
perties of an alloy of iron and nickel. The stone was exceedingly hard 
except where the metallic particles were found, and this made it difficult 
to polish satisfactorily. Chondri " could not be definitely detected.

The specific gravity was found in the usual way and was ascertained 
to be — 
Larger fragment 3-536 
Smaller fragment 3*551 
Both specimens were porous, as was seen during the specific gravity 
■determination. The first specimen weighed in air 1382 2, and in water 
989 5, but the latter weight gradually increased to 991 "4 after one hour's 
immersion, so that water to the extent of 1*9 grammes had been absorbed.
