saloon, blende, could be deposited in this part of the col* 
NAT.hhsr. leetion.— Between this and the substance now 
best known by the name of diallage (in the ad- 
joining and opposite case, No. l6), is placed the 
hypersthene of Haiiy (Labrador hornblende of 
Werner) and the anthophyllit, a substance from 
Kongsberg in Norway, nearly allied to them. — 
The actinote or sirahlstein, of which we have the 
common, glassy and fibrous varieties, likewise 
passes into substances contained in the opposite 
glass case, especially the amiant horde from Oisans 
and the fibrous actinote, which is closely allied 
to some varieties of common asbest. — The tre- 
lnolitc (formerly grammatite of Haiiy, but now 
referred by this crystal lographer to his amphi- 
bole) : among the specimens of this substance 
are, the fine fibrous variety, not unlike in ap- 
pearance to some varieties of a-sbest in the oppo- 
siteglass case; glassy tremolite indolomite andgra- 
nular limestone (see the adjoining case No. 21). 
(Case l6.) Asbest and amianth, with other re- 
lated substances : among these may be observed 
specimens illustrative of the transition from a 
very close to a loose fibrous structure ; various 
specimens of the flexible asbest or amianth, with 
some antique incombustible cloth, paper, &c. 
made of it; the varieties called mountain wood, 
mountain cork, or nectic asbest, &c, separate^
