which results point to (Fe,Ni,)P, as the true representative of its 
composition. It does not accord very well with the analysis of the 
powder, and the relation of one body to the other must be left till 
fresh material comes to hand. 
Mention should here be made of a curious crystal which on two or 
three occasions was met with while searching through the debris of the 
meteorite. It consisted apparently of a square prism, which, while 
the sides were quite bright and metallic, had a square centre of a 
dull almost black colour; it very readily broke across the prism. 
In the paper there is represented such a prism broken across, 
showing the dark centre. An analysis of this compound gave the 
following results :—

which numbers agree with the formula (Fe,Ni,).P. 
Graphite occurs occasionally, but rarely, as nodules; sometimes 
as nodules inclosing troilite, like the one already referred to; some- 
times in large sheet-like masses, in one case about four inches in 
length and two inches wide. A specimen was carefully dried and 
pounded and burnt in a current of oxygen and gave numbers which 
show it to have the composition :—

The nickel-iron was further examined for occluded gases. A 
portion of the nickel-iron borings removed from the under surface 
was selected and was heated in a porcelain tube connected with a 
Sprengel pump. Gas amounting in bulk to 3:59 times the volume 
of the iron was extracted, and was found on analysis to have the 
following composition :—

patch which Dr. Hicks on his sketch-map [Q.J.G.S. vol. xxxv.

the north side. We read [U.c. p. 800], “ Hastward (sic) of this, and
