The remaining substances in this case relate to 
I the hornblende —or amphibolic minerals, which 
are continued in the two next cases: basaltic horn¬ 
blende from Vesuvius, common hornblende, &c. 
Case 15, and part of 16. Continuation of 
amphibolic minerals. Only a few specimens of 
that widely diffused substance, the common horn¬ 
blende, could be deposited in this part of the 
collection.—Between this and the substance 
called diallagite, or diallage (in the adjoin¬ 
ing and opposite case, No. 16), are placed the 
hypersthene of Haiiy ( Labrador hornblende of 
Werner) and the anthophyllite , a substance from 
Kongsberg in Norway, nearly allied to them.— 
The actinolite or strahlstein (of which we have the 
common, glassy, and fibrous varieties) likewise 
passes into substances contained in the opposite 
glass-case, especially the amianthoide from Oisans 
and the fibrous actinote, which is closely allied to 
some varieties of common asbest.—The tremoliie , 
(formerly grammatite of Haiiy, but now referred 
by this mineralogist to his amphibole): among 
the specimensof this substance are,the finefibrous 
variety, not unlike in appearance to some varieties 
of asbest in the opposite glass-case; glassy tre- 
molite in dolomite and granular limestone (see 
the adjoining table-case, No. 21).—The rhceticite , 
a mineral, according to Werner, intermediate be¬ 
tween tremolite and kyanite. 
Case 16 . Asbest and amiantli , with other re¬ 
lated substances : among these may be observed 
specimens
