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 established are :— 
the pyrope or chrome garnet* generally called Bohemian 
garnet* which occurs in rounded grains* and also embed¬ 
ded in serpentine, &c.;—the colophonite , so called from 
its resemblance to rosin* from Norway and North America ; 
—the melaniie * found particularly in the neighbourhood 
of Frascati;—the grossular or Wilui garnet* a fine light- 
green species from Kamschatka* so called from the fancied 
resemblance which its separate crystals bear to a goose¬ 
berry ;—1the allochroite * also called splintery garnet* from 
Drammen in Norway;—the romanzovite. 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 mineralogists ;—the iolite 
or pelioma, now generally called dickroite (from its exhi¬ 
biting two different colours when viewed in different posi¬ 
tions), massive and crystallized* from Capo di Gate* from 
Greenland* Bodenmais in Bavaria* and Orayervi in Fin¬ 
land (steinheilite) ;—the sordawalite from Finland;—the 
karphollte from Bohemia* &c. 
Case 37. This Case contains the following substances : 
—stciurolite, a bisilicate of alumina and of oxide of iron* 
called also granatite and cross-stone* among the specimens 
of which are the fine macled crystals from Brittany* and 
the modifications of the simple crystals from St. Gothard* 
accompanied by prisms of disthene* perfectly similar to 
those of the staurolite* and sometimes longitudinally 
grown together with them.—Silicates containing yttria and 
protoxide of cerium ; viz. the gadolinite, from Ytterby 
and Kararfvet in Sweden ; the allanite from Greenland 
(to which may be referred the cerine of Bastnaes) ; the 
orthite and pyrorthite . 
Silicates containing glucina* the principal species of 
which is the emerald * or beryl * the former being a variety 
which owes its fine green colour to oxide of chromium:
