called fusible augite. The metalloid diallage or dial- 
lagite , also called schiller-spar, from the Hartz, Salz¬ 
burg, &c.; the bronzite and the hyper sthene (Labra¬ 
dor hornblende of Werner), may likewise be referred to 
this tribe of minerals. 
Case 85. Among its contents may be specified the 
mineral substances which have been described under 
the appellations of thallite, arendalite, acanticone, del- 
phinite, &c., which are Werner’s pistacite and are now 
more generally designated by the name of epidote, 
given to them by Haiiy. To this also belongs the man - 
ganesiferous epidote , referred by some to the ores of 
manganese.— Zoisite .—Among the specimens of ido - 
erase (vesuvian of Werner), the more conspicuous are 
the large beautiful crystals (the unibinaire of Haiiy), 
discovered by Laxmann on the banks of the Yilui in 
Kamschatka, imbedded in a steatitic rock ; those from 
Vesuvius, where this substance occurs accompanied by 
other volcanic ejections, have, in Italy* obtained the 
name of Vesuvian gems, hyacinths, and chrysolites;— 
the varieties called egerane , loboite , and that from Tel- 
lemarken in Norway, coloured blue by oxide of copper, 
and known by the name of cyprine;—essonite or cin¬ 
namon-stone, chiefly from Ceylon, which was supposed 
to contain zirconia, till a more accurate analysis proved 
it to be nearly allied to vesuvian : most of the hyacinths 
of commerce are cinnamon-stone. 
Case 86. The greater part of this case is appropri¬ 
ated to the various species and varieties of the garnet 
tribe, formerly divided into noble and common garnets. 
Among the more distinct chemical species now establish¬ 
ed arethe pyrope or chrome garnet* generally called 
Bohemian garnet, which occurs in rounded grains, and 
also imbedded in serpentine, &c.;—the colophonite , so 
called from its resemblance to resin, from Norway and 
North America:—the melanite , found particularly in 
the neighbourhood of Frascati; — the grossular or 
Wilui garnet, a fine light-green species from Kamschat- 
ka, so called from the fancied resemblance which its
