are at times, especially in parts of the Qutahar and Chireya — 
stones, red, like fragments of garnet or zircon. ia 
The meteoric pyrites is present in a ratio of about one-half the 
apparent quantity to that of the iron. lt is generally in little — 
independent particles of the same average size as those of the 
iron; and it sometimes is continuous with the iron in the same — 
particle, like the copper and silver of Lake Superior. ‘4 
The Bulloah stone exhibits less of the ferruginous olivine than _ 
the others around the iron, and may perhaps contain more of the 
barred and grey mineral or minerals. The result is a paler hue 
on it. Its crust, on the other hand, is thicker and coal-black, _ 
that on the other stones having a browner cast. 4 
But the specific gravity of the aerolite seems pretty constant — 
in its different parts, namely about 3°60. a 
The next stone in order to the fragments that fell at Bulloah — 
is the thin slab-like piece that fell at Piprassi. One of the faces —

cave surface. The outer side is flat and smooth. The 
which it stands, and which is the result of the wedge-like form — 
is also smooth, rounded at the edges, and presenting hollows a1 
irregularities on one half of its surface, while to the side of this 
base, on the inner or just below the concave part of the stot 
the irregular piece that fell at Chireya adapts itself. i 
ré t is somewhat pitted and deeply grooved on its upp 
side, and rounded everywhere else. Indeed, notwithstanding t 
‘precision with which it fits to the Qutahar stone, the faces al 
edges at the parts of contact are rounded off so as almost to 0 
arate the original form of the stones at this part. The.
