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; JJ. was similar to J. 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; V. were thick cleavage 
plates; and VI. 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. 
In one of the early notes on the Bruce meteorite published by 
W. Haidinger, in 1862, he wrote “ Vielleicht finden sich in der 
That innerhalb der Meteorisenmassen . . . selbst manche Siattigungs- 
punkte, welche wirklich verschiendene Mineralspecies darstellen.” 
Such an instance presents itself in the thin paper-like pliant plates 
which lie on the faces of the tetrahedra of nickel-iron and between 
the large plates of the crystals of nickel-iron; they are in the form 
of equilateral triangles or are lozenge-shaped, have the thickness of 
stout writing paper, and, unlike the plates of nickel-iron, are quite 
pliant. They are strongly magnetic, are of a pure white colour, and 
have evidently been extruded from the nickel-iron at the time of 
formation. They are soluble in hydrogen chloride and _ nitrate. 
As the examination of them was made in the case of some which 
had been reduced in hydrogen, a further portion picked direct from 
the fragments which had come off the meteorite was taken; both 
kinds were found to be equally pliant. The fresh piates taken 
direct from the meteorite contained 0-688 per cent. of phosphorus. 
Analysis of the plates showed them to consist of :—
