lenticular and coxcomb pyrites, as also the glo- saloo>\ 
bular pyrites of a radiated texture. — The hepatic **at. km 
of liver pyrites of Werner, very distinct from 
what French mineralogists caliper sulfare hdpa- 
tique, which latter is decomposed common and 
radiated iron pyrites and sometimes brown iron 
stone. — Magnetic pyrites, which is nearly related 
to the preceding species ; massive and in six sided 
prisms. — Oxides of iron : magnetic iron stone, 
massive, of various grain, compact, crystallized, 
in serpentine, chlorite slate, &c. ; magnetic iron 
saud. 
(Case 34.) Oxides of iron continued. ^ — Speci- 
mens of specular iron or iron glance, among 
which those from the island of Elba are remarka- 
ble on account of their beautiful iridescence and 
play of colours ; variety in large laminar crystals, 
appearing like polished steel, from Stromboli, 
&c. : the micaceous iron ore of Werner belongs 
partly to this species, partly to the scaly red and 
brown iron stone ; among the most remarkable 
specimens of which is that in delicate, transparent, 
tables of a blood red colour, from Nassau-Siegeri ; 
that in scales coating the cells of lava, o:c. — 
The different varieties of compact red iron stone, 
and of red hematite.
