next case may be considered the leucite (amphigfene 
of 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 noble garnet is that in 
curved-lamellar concretions, found massive in Green - 
land .—The pyropey or Bohemian garnet, in rounded 
grains, &c.—^The common gamet, the predominant 
colours of which are brown and green: among these 
may be mentioned the variety which, from its re¬ 
semblance to rosin, is called colophonite. To this 
also belongs the elegant variety from Kamschatka, 
denominated grossulary 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 allochroitey 
also called splintery garnet, from Drammen in Nor¬ 
way.—^The aplonwy whose dodecahedral crystals 
differ from those of the garnet in being streaked in 
the direction of the short diagonal of their rhom- 
boidal planes.—The dnnamon-stone from Ceylon, 
a mineral, which was supposed to contain zircoriia, 
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 true hyacinth.
