Nat. Hist, 
oflhne: the sparry (Esmark’s datholite) and the 
globular fibrous variety of the same (the hotryo- 
lite of Hausmann), two scarce Norwegian mine¬ 
rals. 
Case 26 ** contains the barytic salts, uz, the 
sulphates and carbonates of barytes. Among the 
subspecies and varieties of the former, called also 
heavyspar and baroselenite, are, the straight- 
lamellar, variously crystallized, the curved-la* 
mellar, the columnar and prismatic ; also the 
radiated variety known by the name of Bologna 
spar, from Monte Paterno near Bologna, and 
from Bavaria; the compact, called ponderous 
marble, including the fetid barytes or hepatite, 
&c. 
Among the specimens of carbonate of barytes^ 
or witherite, may be particularized the beautiful 
groups of double six-sided pyramids, and those 
of six-sided prismatic crystals. 
Case 27. Strontian salts; carbonate of Stro7i- 
tian^ also called strontianite, in prismatic and 
acicular crystals, which latter have sometimes 
been mistaken for arragonite.—Among the sul¬ 
phates of strontian (celestine of Werner) the more 
remarkable specimens are, the splendid groups 
of limpid prismatic crystals from La Catolica in 
Sicily; the acicular variety in the hollows of 
compact sulphate of strontian, from Montmartre; 
the same in fissures of flint; the radiated and 
fibrous celestine, he. 
The remainder of this case is occupied by
