ing places seemed to be the hardest parts : hence perhaps the 
reason of the surface being uneven, and a little pinny. Not- 
withstanding this uneven and pinny_ appearance of the filed 
surface, a polish was produced, which was I think at least 
equal, if not superior, in brilliancy and smoothness to that 
of any steel I ever saw. The wootz filings were attracted 
by the magnet like common iron filings. 
A cake of this substance being broken in the part nearly cut 
through, the fracture exhibited the grain and colour of rather 
open grained steel, but it was not nearly so open as I have con- 
stantly seen the grain of a bar of cement, or blister steel. The 
grain of wootz was most like that of blister steel which has 
been heated and hammered a little, and also like some kinds 
of refined crude iron. 
The specific gravity of wootz, and several specimens of steel 
and iron, was found, by Mr. More and myself, to be as follows. 
No. 1. Wootz - — - - 7.181 
No. 2. Another specimen of wootz - 7. 403 
No. 3. Ditto forged - - - 7-647 
No. 4. Another specimen, forged - - 7 .503 
No. 5. Wootz which had been melted - 7.200 
No. 6 . Wootz which had been quenched while white 
hot - — — - - 7.1 66 
No. 7. Bar steel from Oeregrund iron — 7.3 13 
No. 8. Ditto hammered — - — 7-735 
No. 9. German steel bar, said to be directly from the ore 7.500 
No. 10. Ditto quenched when white hot - 7.370 
No. 11. Melted steel wire — - - 7.500 
No. 12. Ditto, another parcel — - 7.460 
No. 13. Piece of hammered Oeregrund steel bar after 
quenching when white hot - - - 7*555
