[north 
marble, &c. ; fetid baroselenite or hepatite , an intimate mixture of sul¬ 
phate of baryta with bituminous matter ; earthy baroselenite: —the 
wolnyne from Muzsay in Hungary, which is only a variety of sul¬ 
phate of baryta. 
Case 53. Sulphate of baryta and sulphate of strontia :—among the 
specimens of the latter salt, to which has been given the name of 
celestine , on account of the sky-blue tint of some of its varieties, the 
most remarkable are, the splendid groups of limpid prismatic crystals 
from La Catolica in Sicily, accompanied by sulphur ; those from the 
vicinity of Bristol, from St. Beat in the Dep. des Landes; those 
from Falkenstein in Tyrol; from the salt mines of Aranjuez; the 
acicular variety in the hollows of compact sulphate of strontia from 
Montmartre; in the fissures of flint and in chalk, from Meudon ; the 
radiated and fibrous celestine from Pennsylvania, Sec. 
Case 54 contains the sulphates of lime , the principal varieties of 
which are,—the selenite* or sparry gypsum , in detached crystals and 
splendid groups, from Bex in Swisserland, Montmartre near Paris, Ox¬ 
ford, &c. ; from St. Jago di Compostela, stained by red iron ochre; 
the fibrous gypsum with silky lustre, from Derbyshire, Swisserland, 
Montserrat; the granular gypsum or alabaster ; the compact variety, to 
which belongs the stalagmitical gypsum from Guadaloupe; the scaly 
gypsum (chaux sulphatee niviforme of Hatiy) from Montmartre ; com¬ 
mon earthy gypsum, &c .—Anhydrous sulphate of lime , or anhydrite, 
(also called cube-spar and muriacite ,) crystalline, fibrous, granular and 
compact; to the last of which belong some of the Italian varieties 
known by the name of bardiglio and bardiglione , as also the singular 
fibrous-compact variety, familiarly called tripe-stone (pierre des trippes), 
from the salt mines of Wieliczka. 
Case 55. Sulphates continued :— sulphate of magnesia , or epsomite, 
generally occurring in crystalline fibres : the fine variety from Calatayud 
in Arragon ; also the haar salz (capillary salt) of Idria belongs to this 
species, and the stalactic cobalt-vitriol, as it is called, from Herrengrund 
in Hungary, which is only sulphate of magnesia, coloured red by oxide 
of cobalt.— Polyhalite , a chemical compound of several sulphates, 
formerly mistaken for anhydrous sulphate of lime: compact and fibrous, 
from the salt formation of Berchtesgaden in Bavaria, and Ischel in 
Austria.— Sulphate of zinc , white vitriol or gallitzinite. — Sulphate of 
iron , green vitriol , or melantherite, (a salt mostly produced by the de¬ 
composition of iron pyrites,) in beautiful large rliombohedral crystals, 
from Bodenmais in Bavaria, and massive, and in stalactic-fibrous forms, 
such as the specimens from the Rammelsberg, in the Hartz, where it 
also occurs in the form of yellow scales, known by the name of misy ; 
and as concretions of a red colour, called vitriol-roth or botryogene : 
the plumose vitriol ( federsalz ), and a botryoidal-reniform substance 
called bergbutter, are nothing but casual mixtures of sulphate of iron and 
hydrous sulphate of alumina.— Sulphate of copper , or copper vitriol :— 
the finest sky-blue specimens here deposited, together with the stalactic, 
fibrous and crystallized varieties, (the large group of crystals is artificially 
prepared,) are from Herrengrund in Hungary. There are also two or 
* A remarkably fine group of selenite crystals is placed on a separate stand be¬ 
tween Table 54 and the window : it is from Herzog Ernst level, Reinhardsbrunn, 
Saxe-Coburg. Presented by H. R. H. Prince Albert.
