blende, including the pargasite; —the actinolite 
or strahlstein (divided by Werner into the 
glassy, common, and fibrous varieties);—the 
grammatite or tremolite , (so called from Val 
Tremola, where, however, it is not found,) 
among the specimens of which are the fine, 
fibrous variety, resembling asbest; the glassy 
tremolite, in dolomite and granular limestone, 
&c.— Cummingtonite . 
Case 33. Part of this Case is filled with the 
mineral substances called asbestine , many of 
which appear to pass into some of the varieties 
of amphibole in the preceding glass Case. 
Among these may be observed specimens illus¬ 
trative of the transition from a very close to a 
loose, fibrous structure ;—several varieties of the 
flexible asbest or amianth , with some antique 
incombustible cloth, paper, &c. made of it;—* 
the varieties called common and schiller-asbest, 
mountain wood, mountain cork, or nectic as¬ 
best, &c., separate, and in combination with 
other substances.— The remainder of this 
Case contains pyroxenic minerals:— augite , in 
separate crystals, and imbedded in lava from 
Vesuvius, together with groups of well-defined 
crystals from Arendahl in Norway, where this 
substance occurs in primitive rocks ;—the gra¬ 
nular variety called coccolite ;—the varieties of 
diopside, at first considered as a distinct spe¬ 
cies, including the mussite and alalite from 
Piedmont;
