and the hauyne , a mineral so named in honour 
of the late celebrated French crystallographer. 
Intermediate between the zeolitic substances and 
feldspar, are placed some mineral species which 
cannot be referred to either of these tribes: among 
them are the meionite and sommite , both from 
Vesuvius ; the scapolite , a Norwegian mineral, of 
which several varieties are known under differ¬ 
ent names, such as the vitreous scapolite, the 
compact and the common scapolite (called also 
wernerite , after the late illustrious professor of 
Freiberg); the talc-like scapolite (micarelle of 
some authors), &c.; the bergmcinnite and the 
fettstein of Werner are related to these.—Distinct 
from these is the socialite , from Greenland, and a 
new concomitant substance, the eudialyte of 
Stromeyer, composed chiefly of silica, zirconia, 
and soda.—In this table-case also begins the suite 
of specimens of feldspar , which is continued in 
the next case ; specimens of compact feldspar 
among which are, the red variety from Sweden, 
frequently mistaken for hornstone; the weiss- 
stein of Werner; the feldspath compacte tenace 
of Haiiy, which is the same as the jade of Saus- 
sure, called by some saussurite, &c. 
Case 12 . In this glass-case are deposited the 
different varieties of the Labrador feldspar , the 
naker feldspar, or adularia, and the common felcL 
spar.—Amongthespecimensof Labrador feldspar
