paper, &c,, made of —^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 yellow ashest 
from South Africa, for the former of w'hich the name of krokydolite has 
been proposed; and which, if the analysis given of it be correct, is re 
ferable to the silicates of iron. The remainder of this Case and part of 
the next contain pyroxenic minerals:— augite, in separate crystals, and 
embedded in lava from Vesuvius, together with groups of well-defined 
crystals from Arendal in Norway, where this substance occurs in primitive 
rocks;—the jeffersonite —the granular variety called coccolite; —the 
hypersthene and paulite {Labrador hornblende of Werner);—the va¬ 
rieties of diopside, at first considered as distinct species, including the 
mussite and alalite from Piedmont;—the sahlite or malacolite, to which 
also belongs the baikalite, of which a few fine specimens are here de¬ 
posited ; the pyrgome or fassaite, and the achmite. 
Case 35. Among its contents may be particularized the mineral sub¬ 
stances which have been described under the appellations of thallite, 
arendalite, acanticone, delphinite, &c. ; most of these are Werner’s jois- 
tacite and are now more generally designated by the name of epidote, 
given to them by Haiiy. To this also belongs the manganesiferons epi- 
dote, considered by some as an ore of manganese.— Cunmingtonite .— 
Zoisite _Among the specimens of idocrase (vesuvian of Werner), the 
more conspicuous are the large beautiful crystals (the unibinaire of 
Haiiy), discovered by Laxmann on the banks of the Vilui in Karaschatka, 
embedded in a steatitic rock; those from Vesuvius, w'here 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 Tellemarken in Norw’ay, coloured 
blue by oxide of copper, and known by the name of cyprine. 
Case 36. The greater part of this Case is appropriated to the various 
species and varieties of the garnet tribe, formerly divided into noble and 
common garnets. Among the more distinct chemical species now esta¬ 
blished are;—the chrome-garnets, to which belongs the pyrope; — the 
lime-garnets, comprising chieliy the melanite from the vicinity of Frascati, 
and some brownish-black varieties, the colophonite, bearing a distant re¬ 
semblance to rosin, from Norway and North America ; the grossular or 
Wilui garnet, a fine light-green species from Kamschatka, so called 
from the fancied resemblance w’hich its separate crystals bear to a goose¬ 
berry ; the allochroite, also called splintery garnet, from Norway ; the 
romanzovite; the essonite (hesHonite) or cinnamon-stone, chiefly from 
Ceylon, which was supposed to contain zirconia, till a more accurate 
analysis proved it to be nearly allied to vesuvian and garnet: most of 
the hyacinths of commerce are cinnamon-stone. In this Case are also 
deposited—the gehlenite, from the Monzoni in Tyrol, to which species 
the melilite from Capo di Bove, near Rome, is referred by some mi¬ 
neralogists ;—the iolite or pelioma, now generally called dichroite (from 
its exhibiting two dilferent colours when viewed in different positions), 
massive and crystallized, from Capo di Gate, from Greenland, Boden- 
mais in Bavaria, and Orayervi in Finland (steinheilite); —the sGrda7va- 
AYe from Finland;—the karpholite from Bohemia, &c. 
Case 37. One half of this Table Case is set apart for tlue silicates 
containing glucina and alumina, the principal species of which is the 
beryl, including the emerald, a gem which owes its beautiful green
