J. L. Smith— Description of Meteoric Stones. 221 
have specimens two millimeters in diameter. It resembles more 
closely the Aussun stone than any other I know of, although 
much more friable. This peculiar gullet so often seen in 
many parts of meteoric stones, has rec ently attracted muc 
attention, Professor Tschermak, of pares paving recently 
published an interesting paper on the subjec 
The specific gravity of the stone, taken ooh several average 
specimens, is 3:55. There is nothing peculiar about the coat- 
ing on the specimens I have examined; it is of a dull black 
and quite rough. 
Chemical examination.—The stony part of the meteorite 
separated almost perfectly from the metallic part still on 
a notable portion of troilite ok could not be separat 
chanically. The amount of sulphur found in that part of ‘the 
meteorite indicated the amount of troilite treme viz: 3°31. 
The stony material, when treated with chlorhydric acid over a 
water bath, affords soluble part 47-80 per cent, insoluble 52:20 
per cent, and is constituted as follows: 
Soluble part, per cent. Insoluble part, per cent.

I separated some of the globules perfectly free from the inter- 
vening matrix, which is easily done oy rubbing a piece of the 
stone between the fingers. Very minute specks of iron could 
be distinguished on them, and when sh kee and treated with 
chlorhydric acid, they gave about the same result as the ma- 
a viz: soluble, 46°80 per cent; insoluble, 53-20 per cent; and 
magnesia in ‘the soluble part was 34°48 per cent, showing 
clensly that they were merely concretions of the matrix of the
