beautiful crystals (the unibinaire of Haiiy) dis- i 
covered by Laxmaun on the banks of the Vilui I 
in Kamschatka, imbedded in a steatitic rock ; 
those from Vesuvius, where this substance oc- : 
curs accompanied by other volcanic ejections, : 
have, in Italy, obtained the appellation of vol¬ 
canic gems, hyacinths, and chrysolites.— Gehle- 
nite,—in this case, though not very closely 
allied to the garnet tribe, is also deposited the 
staurolite (called also grenatite and cross-stone): 
besides several varieties of the cruciform and 
other crystals from Britany, we have modifica¬ 
tions of the simple crystals in mica-slate from 
St. Gothard, accompanied by prisms of kyanite 
perfectly similar to those of the staurolite, and 
sometimes longitudinally grown together with 
them. 
Case 14. The contents of this table-case 
are :— chrysolite and olivine (peridot of Hauy), 
the former crystallized, and in cut and polished 
pieces ; the latter as grains, in basaltic rocks 
and separate : to which is added some of the 
olivine-like substance found in the cells of the 
Siberian meteoric iron (Case 49). —The sub¬ 
stances which have been described under the 
names of thallite, arendalite, akantikone, delphi- 
nite, &c. are Haiiy’s epidote, and Werner’s pista- 
cite : of which several specimens are deposited in 
this case. Among these is also the violet manga- 
nesiferous epidote^ referred by some to the ores of 
manganese .——Axinitey variously crys¬
