[*Read before the Royal Society ap aee New South Wales, 8 December, 1880.] 
A PRELIMINARY notice of the pian ae general structure and 
chemical composition of this v meteorite was laid 
before the Royal Society of Now "South ales in 1872, and 
published in its volume for that aoe weet then I have been 
able to do a little more towards its examina 
Without repeating the details of “the comieai already given, 
I may remind you that the meteorite belongs. to the class known 
as siderolites, i.¢., it is made up of a mixture of various silicates wit 
some metallic nickeliferous iron. Externally it is covered with a 
fused skin, and the outer portions, to the depth of about 
an inch, are distinctly laminated. This laminated or concentric 
is probably due to the unequal expansion of the outer 
portion when the meteorite was in eicnetshentad during its passage.
