mispikel), the sulphurets of iron, viz, the common 
pyrites smooth and striated ; the radiated pyrites^ 
a substance very subject to decomposition, and to 
which belong most of the varieties of what is com¬ 
monly called lenticular and coxcomb pyrites, as 
also the globular pyrites of a radiated texture. 
Case 37. Sulphurets of iron continued:—The 
hepatic or liver pyrites of Werner, very distinct 
from what French mineralogists call fer sulfure 
hepatique, which latter is decomposed common 
and radiated iron pyrites, and sometimes brown 
iron stone.— Magnetic pyrites, which is nearly 
allied to the preceding species : massive and 
crystallized in six-sided prisms.—The remainder 
of this table-case is occupied by part of the oxides 
of iron : magnetic iron-stone massive^ of various 
grain, compact, crystallized, in serpentine, chlo¬ 
rite slate, &c. ; ore which yields the vcootz, a 
very hard kind of iron from the East Indies; 
magnetic iron-sand; the variety of oxidulous 
iron with admixed manganese and zinc, called 
franklinite, from New York, &c. 
Case 38, and part of 39. Oxides of iron 
continued : specimens of specular iron\ or iron 
glance, among which those from the Island of 
Elba are remarkable on account of their Feautiful 
iridescence and play of colours \ variety in large 
laminar crystals, appearing like polished steel, 
from Stromsboli, &c.; the micaceous iron ore of 
VvYrner, belonging partly to this species, partly 
to the scaly red and brown iron-stone (in the
