chroite , also called splintery garnet, from Drammen in 
Norway ;—the romanzovite. In this Case are also de¬ 
posited—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 dichroite (from its ex¬ 
hibiting two different colours when viewed in different 
positions), massive and crystallized, from Capo di Gate, 
from Greenland, Bodenmais in Bavaria, and Orayervi 
in Finland (steinheilite) the sordawalite from Fin¬ 
land ;—the karpkolite from Bohemia, &c. 
Case 37. This Case contains the following sub- 
stances:— 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 Ka- 
rarfvet 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 bei'yl, 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 
Adontchelong in Siberia ; the large beryls of Limoges, 
and from Acworth in New Hampshire, where crystals 
weighing upwards 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,
