petrifactions of the order of corals ; fetid lime¬ 
stone &c. 
Cases 23 and 24. These cases are occupied 
by suites of brown spar and of arragonile. Among 
the specimens of the former are many of the scarce 
fibrous varieties, which were formerly referred to 
common fibrous limestone ; among the latter are 
Werner’s columnar and acicular arragonite. as 
also fine specimens of the remarkable coralloid 
variety from Eisenertz in Styria, formerly called 
fios ferru 
Case 25 . contains the fluatesoflime. Among 
the numerous varieties of fluor spar may be par¬ 
ticularized the rose-coloured primitive crystals 
from Chamouni; the phosphorescent massive 
fluor spar, called chlorophane, from Siberia : the 
varieties called fortification fluor; earthy and 
compact fluor, &c. 
Case 26 . contains the sulphates of lime, which 
are divided into selenite or sparry gypsum, of 
which several regularly crystallized, acicular and 
lenticular varieties are deposited ; fibrous gyp¬ 
sum with silky lustre; foliated and Compact 
gypsum, to which latter belongs the stalagmitical 
variety from Guadaloupe ; and the earthy or 
frothy gypsum, to which may be referred Haiiy’s 
niviform variety of sulphate of lime.—The re¬ 
mainder of this case is occupied by the anhydrous 
sulphate of lime , or the cube spar and muriacite of 
Werner, the compact variety of which is, in some 
parts of Italy, known by the name of bardiglione. 
Case 26*.
