seen. Small portions of the surface were submitted to higher magaifica- 
tion, and Figs. 11, 12 and 13 are the results. In Fig. 11 is shown a 
complete crystal, which had a very bright border line, the edges 
glistening like silver beads under reflected light. The magnification in 
this case is about 20. Fig. 12 shows another portion; the different 
reflecting powers of the various constituents enable the individual 
crystals to stand out clearly from each other. 
Figs. 13 and 14 show portions of one of the veins magnified 20 dia- 
meters ; the carbonaceous matter filling the network is here well defined. 
At low magnification the etched figures are not so well defined as is 
usually the case with meteoric irons. The reason for this will be clear

when the chemical composition has been explained. The striking feature of 
the structure seemed to be the presence of the veins composed of a material 
differing considerably in composition from that of the general mass. 
The meteorite is very readily attacked by acids, as might be expected 
from its purely metallic nature. It dissolves completely in aqua regia, 
with the exception of a small quantity of earthy matter, which I believe 
is located only in the veins. Dilute sulphuric also attacked it, but in 
this case there is an insoluble residue composed of carbon, and also 
crystals of an alloy of iron and nickel. Practically nothing but iron goes 
into solution in dilute sulphuric acid, the iron-nickel alloy being insoluble, 
►but dissolving readily in aqua regia. 
A small piece of the meteorite with a vein running through it was.
