distant resemblance this substance bears to some 
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 arragonite . 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 
flos ferri . 
(Case 25 .) contains the fnates of lime. 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 
d Werner!
