separate crystals bear to a gooseberry;—the allo- 
chroite, also called splintery garnet, from Drammen in 
Norway ;—the romanzovite. In this Case are also de¬ 
posited—th e 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, 
Greenland, and Orayervi in Finland ( steinheilite );— 
sov daw edit e from Finland ;—the karpholite from Bo¬ 
hemia, &c. 
Case 37. This Case contains the following sub¬ 
stances :— staurolite , a bisilicate of alumine 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 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 Salz¬ 
burg;—beryls of various colours, the more common 
of which is the variety called aquamarine; the per¬ 
fectly white and limpid, and fine oil green varieties 
from Nerchinsk and Adontclielong in Siberia ; the large 
beryls of Limoges, and from Ac worth in New Hampshire, 
w r here crystals of upwards of fifty-nine pounds have 
been found, (the fragment of a prism in the centre of 
the Table Case weighs forty-three pounds);—the eu - 
clase , a rare crystallized mineral substance, discovered 
by Dombey in Peru, but since only found, as loose 
crystals,
