DR. W. FLIGHT ON THE METEORITES OF 
and the greater part of the insoluble ingredients was found to consist of very minute 
bright apparently square prisms, which pervade all the nickel-iron, and apparently 
constitute nearly 1 per cent, of its mass. These prisms are acted upon very slowly and 
with considerable difficulty by hydrogen chloride, but disappear readily in hydrogen 
nitrate. But I shall return to the consideration of the characters and composition of 
the prisms later on. The absence of all combined carbon was fully established. The 
nickel-iron thus dissolved was found to contain of:

Some of the largest nickel-iron crystals, and cleavages of them, were examined for 
other constituents than iron with the following results :—I. was a tetrahedron of iron 
with cleavages parallel to the faces of the tetrahedron; II. was similar to I. but 
thinner; III. were several examples of cleavage plates, firm not pliant, thicker than 
the paper-like plates which will be described later on; IV. were thinner plates, but 
not pliant ones; Y. were thick cleavage plates; and YI. some borings. The following 
ingredients were met with :—

The rusted fragments of the meteorite, which were very carefully picked over, 
yielded many very good crystals of nickel-iron. These were reduced in porcelain tubes 
in hydrogen, a large quantity of hydrogen chloride was extracted from them, and 
dozens of perfectly complete tetrahedra of nickel-iron as well as many cleavage pieces 
with sharp edges were safely preserved.

meteorite. 
In one of the early notes on the Bruce meteorite published by W. Haidtnger, in 
1862, he wrote : “ Yielleicht finden sicbin der That innerhalb der Meteoreisenmassen
