m 
stone, &c.;— pinite , crystallized in regular hexagonal 
prisms, and gieseckite, from Greenland, which appears 
to be a variety of it. 
Case 33. This and part of the following Case chiefly 
contain substances related to hornblende or amphibo¬ 
lic minerals, among which may be specified the basaltic 
and common hornblende, including the pargasite; —the 
actinolite or strahlstein (divided by Werner into the 
glassy, common, and fibrous varieties);—the gramma - 
\iite or tremolite (so called from Val Tremola, where, 
however, it is not found), among the specimens of which 
are the fine, fibrous varieties, resembling asbest; the 
glassy tremolite, in dolomite and granular limestone, 
& c .—A rfvedsonite—A n th opliyllite . 
Case 34. Part of this Case is filled with the mine¬ 
ral 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 illustrative of the transition from a very close 
to a loose, fibrous structure ;—several varieties of the 
flexible asbest or amianth , with some antique incom¬ 
bustible cloth, paper, &c. made of it;—the varieties 
called common and schiller-asbest, mountain wood, 
mountain cork, or nectic asbest, &c., separate and in 
combination with other substances;—the blue and yet - 
loiv asbest from South Africa to which the name of kro- 
kydalite has been given. The remainder of this Case 
contains pyroxenic minerals :— augite , in separate crys¬ 
tals, 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 joffersonite; —the granular variety called coc- 
colite; —the varieties of diopside , at first considered as 
a distinct species, including the mussite and alalite from 
Piedmont; —the sahlite or malacolite, to which also be¬ 
longs the baikalite, of which a few fine specimens are 
here deposited ; the pyrgome or fassaite, and the ach - 
mite. The metalloid diallage or diallagite , also called 
schiller-spar, from the Hartz, Salzburg, &c., the bronzite
