The history of this meteorite has already been fully dealt 
with. 
The following notes on its chemical and mineralogical com- 
position, unless stated otherwise, have been taken from Flight’s 
report (22, reprinted 23). The specimen was found to consist 
entirely of metallic minerals, containing no rocky matter 
whatever. 
It decayed to a considerable extent ; fragments oxidized and 
crumbled off, and drops of iron chloride exuded here and there. 
The part of the meteorite so rapidly decaying presented a very 
marked crystalline character ; and the tetrahedral structure broke 
up into plates, between which were very thin plates of another 
constituent (taenite), less subject to change. The action of 
moisture on these series of plates was like that of the exciting 
liquid of a galvanic cell, and caused the oxidation to proceed very 
rapidly. 
Neumayer (42, p. 25) took the specific gravity of four specimens 
of the iron, and one of the crust. The former gave 7‘ 12, 7 * 51, 7' 51, 
7 ‘60 respectively, and the latter 3 '66. Flight states that these 
pieces were taken from the Cranbourne No. 2, but reference to the 
original paper shows that this was not so. 
Foord (24, p. 426) gives the specific gravity of the block in his 
possession as 7 '5215. 
Nickel-irons. — A portion of the iron connected with a Bunsen 
cell was treated in a solution of salt in a sealed vessel, for the purpose 
of determining whether the iron contained any combined carbon. 
The absence of the latter was said to be fully established. 
The greater part of the insoluble ingredients consisted of rhabdite 
in the form of very minute, bright, apparently square prisms, which
