Experiment 2nd. ‘Fhe Anthracite of Rhode Island, by 
the action of the blowpipe, presented a brownish appearance 
after cooling, (owing to manganese.) The surface exhibited 
numerous globules, larger than those of the Lehigh; some 
of them were transparent, colourless, and very brilliant by 
reflected light; others, and the most abundant, were black 
and opaque, and were strongly attracted by the magnet; a 
few were coloured white and black in spots; the white spots 
resembling enamel. ‘Che surface of the mass presented 
minute veins similar to those of the Lehigh. 
Some of the black globules were heated for a long time on 
platina foil, with carbonate of soda; the mass was yellowish, 
but became black when immersed in water. By heating and 
dipping into water several times, the globules whitened; I 
could not effect their fusion in this way, but with the com- 
pound flux they readily fused. With this flux the different 
kinds were tried, and with the same effect.

* It is rather singular that so great a quantity of water as is contained 
in Anthracite, should heretofore have escaped notice. It is my inten- 
tion to examine all the different kinds of coal, to ascertain if this fact 
he renerel.
