ACCOUNT of the IRON MINE 72 the ISLE 
of ELBA, by M. 
DRAI. Fourn. de Phyf. Vi. 52. 
OF all the kinds of. iron ore, none has 
obtained more notice than'that Of Elba, 
both on account of its fingular beauty and 
richnefs, ‘and the peculiar fituation in 
which itis found. It is the general opi- 
nion that the whole of the ifland is an en- 
tire mafs of iron ore, and that inapproach- 
ing it from the fea, the compafs is fo much 
affected by it, as no longer to preferve its 
polarity. Both thefe reports are, how- 
ever, almoft equally fabulous. The iron, 
though extremely’ abundant, is only found 
in one particular diftri&, and the ore it-, 
felf ig not in the fmalleft degree capable of 
affecting the magnet. - ; 
The oniy minethat has ever been worked 
zn this iflend, is fituated on the weftern 
fide clo’ to the channel of Piombino, which 
feparates Elba from the main land of Italy..
