SALOON, next case may be considered the leucite (amphig^ne 
NaTITist Haiiy), of which this, case contains several cry¬ 
stals belonging to the trapezoidal modification, in 
their fresh and altered state, both loose and imbed¬ 
ded in lava. 
(^Case 13.) is principally appropriated to the sub¬ 
stances of the garnet tribe. Among the more re¬ 
markable varieties of the iiohlt garnet is that in 
curved-lamellar concretions, found massive in Green¬ 
land.— ThQ pyrope, or Bohemian garnet, in rounded 
grains, &c.—The common garnet^ the predominant 
colours of \vhich are brown and green: among these 
may be mentioned the variety which, from its re¬ 
semblance to rosin, is called colopJionite. .To this 
also belongs the elegant variety from Kamschatka, 
denominated grossalar, on account of the resem¬ 
blance which its separate crystals bear to a goose¬ 
berry.—Trapezoidal and emarginated crystals of the 
black garnets, called melanite^ found particularly in 
the neighbourhood of Frascati.—The allochroite, 
also called splintery garnet, from Drammen in Nor¬ 
way.—The aplome, whose dodecahedral crystals 
differ from those of the garnet in being streaked in 
the direction of the short diagonal of tlieir rhom- 
boidal planes.—The cinnamon-stone from Ceylbn, 
a mineral, which was supposed to contain zirconia, 
till a more accurate analysis proved it to be a sub¬ 
stance nearly allied to garnet and vesuvian: some 
polished pieces of the same, being the U’ue hyacinth.
