also belongs the elegant variety from Kamschatka/ 
denominated grossular , 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 aUochroite, 
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 their rhom- 
boidal planes.—The cinnamon-stone from Ceylon, 
a mineral, which was supposed to contain zirconia, 
till a more accurate analysis proved it to be a sub¬ 
stance nearly allied to garnet andvesuvian: some 
polished pieces of the same, being the true hyacinth. 
—Among the specimens of vesuvian or idocrase, 
the more conspicuous are the large beautiful cry¬ 
stals (the unibinaire of Haiiy) discovered by Lax- 
mann on the banks of the Vilui in Kamschatka, im¬ 
bedded in a steatitic rock; those from Vesuvius, 
where this substance occurs accompanied by other 
volcanic ejections, have, in Italy, obtained the trivial 
rihmes of volcanic gems, hyacinths and chrysolites, 
— Gehleniie. —In this case are also deposited, though 
not very closely allied to the garnet tribe, the staa- 
rolite (called grenatite in Switzerland): besides se¬ 
veral varieties of the cruciform and other crystals 
from Britany, we have modifications of the simple 
crystals in mica-slate from St. Gothard, accompa¬ 
nied by prisms of kyanite perfectly similar to those 
of
