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 ;—the 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 dichroile (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 
karpholite from Bohemia, &c. 
Case 37. This Case contains the following substances: 
— staurolite, 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: 
from Santa Fe, from Mount Zahara in Egypt, and from 
Heubachthal in Salzburg, embedded in mica slate;—beryls 
of various colours, the more common of which is the variety 
called aquamarine ; the perfectly white and limpid, and 
fine oil green varieties from Nerchinsk and Odontchelong 
in Siberia; the large beryls of Limoges, and from Ac- 
worth in New Hampshire, where crystals weighing up¬ 
wards of fifty-nine pounds have been found, (the fragment 
of a prism in the centre of the Case weighs nearly forty- 
three pounds) ;—the euclase , a rare crystallized mineral 
substance, discovered by Dombey in Peru, but since only 
found, as loose crystals, at Capao, near Villaricca, in Bra¬ 
zil, and in the chlorite slate of that neighbourhood;—
