2 74 Mr. Mornay’s account of the discovery 
wherever the mass is struck with a steel, it gives out sparks 
abundantly. 
When rubbed with a quartzous pebble in the dark, it be- 
comes beautifully luminous. 
The block is magnetic, and even possesses well marked 
poles. In the outline I have indicated their position. The 
N. pole is not so well characterized at the shorter point of 
the same end. 
The N. pole of the block lies at present nearly E.N.E*;

able to give me much information, being a very intelligent 
man. 
The N. pole is by much the most massive end, and lay

No part of the mass has the power of attracting iron filings, 
whether the spot have been filed to brightness or not. 
I had provided myself with a sledge hammer and tools for 
cutting off some specimens of the iron, but it was with the 
utmost difficulty that I could detach the few small pieces 
which you have seen, one of which I gave to you on my arrival 
in England. The largest I presented to my Lord Dundas, 
to whom I am under many obligations, and who promised to

and to Dr. Marcet. Another specimen, beautifully crystal-

small pieces left. As soon as the first piece was detached, I 
was struck with the appearance of internal crystallization not
