this was found to be some compound of iron which was attracted by 
the magnet. This resinous substance before being submitted to heat

Amber is sometimes inclosed in jet, and it occurs in brown coal 
at Hasen Island in Greenland &c. The melite, a sort of resin ap¬ 
parently, occurs in bituminous wood.
