The metal, which is somewhat malleable, exhibits when

slight precipitate of sulphuret. The insoluble residue retained 
the form of the original fragment, and consisted of brilliant scales 
of graphite, a black, flocky substance and a magnetic portion, 
which under the microscope appeared to be a network of erys- 
talline plates, intersecting each other at angles of about 60° and 
120°, exactly resembling the figures, exhibited by an etched sur- 
ace of the mass at this place. The magnetic portion was fused 
with carbonate and nitrate of soda. The mass, which was col-
