the Carbonates: — carbonate of soda, among 
which is the African trona; — carbonate of 
strontia, also called strontianite, in prismatic 
and acicular crystals, which latter have some¬ 
times been mistaken for arragonite ;— carbonate 
of barytes or miherite, among the specimens of 
which may be particularised the beautiful 
groups of double six-sided pyramids, and those 
of six-sided prismatic crystals;— barytocalcite. 
Case 41. Carbonate of lime . The whole of 
this Table Case is appropriated to the species 
called arragonite , among the principal speci¬ 
mens of which are the groups of prismatic crys¬ 
tals from Kosel, Bohemia, Arragon, &c., those 
of the coralloid variety of this substance from 
Eisenertz in Stiria, formerly called flosferri, &c. 
To the massive varieties some of the calcareous 
deposits of Carlsbad in Bohemia may be referred. 
The carbonates will extend to Case 51 ; the 
remaining Table Cases on the south side of the 
Gallery will be occupied by the various ar - 
seniates, 'phosphates , sulphates, and by the haloid 
salts , consisting of combinations of chlorine and 
fluorine with other bodies. 
In the upright Glass Cases of the eastern wall 
of the centre compartment is deposited a col¬

presented by his late Majesty King George IV.
