San-Felippe in Tuscany, where moulds of medals, 
gems, &c. are placed in convenient situations to 
receive the calcareous deposition.—As a continua¬ 
tion of the compact limestone in the last case, 
we have in this, the shell limestone, the most 
esteemed variety of which is that from Carinthia, 
“ called lumachella or fire marble. 
(Case 23.) Of the carbonates of lime deposit¬ 
ed in this case the most remarkable are the va¬ 
rieties of slate spar (schiefer-spath of Werner), 
those of brown spar, and particularly those of 
arragonite, among the crystallized varieties of 
which is that from Iglo in Hungary, called igloit 
by some mineralogists; also magnificent speci¬ 
mens of the remarkable coralioid variety of ar¬ 
ragonite from Eisenertzin Styria, formerly called 
jlos ferri. 
(Case 24.) Contains the fiuates of lime.-— 
Among the numerous varieties of fluor spar, 
maybe particularized the rose coloured primitive 
crystals from Chamouni ; the chlorophane from 
Siberia; the singular, pale seladon-green, oc- 
tohedal variety from Beeralston, in Devonshire, 
with white earthy fluor interposed between its 
laminae; the varieties called fortification fluor; 
earthy and compact fluor, &c. 
(Case 25 and part of 2 6 .) The remaining 
calcareous salts, viz. the phosphates, sulphates
