PHYSIOGRAPHY. CLASS II. 



of Feld-spar, &c. Also Omphazite occurs in beds with 

 rhombohedral Quartz, dodecahedral Garnet, hemi-prismatic 

 Augite-spar, &c. Diopside occurs in veins traversing ser- 

 pentine, with dodecahedral Garnet and prismatic Talc- 

 mica, and Fassaite and Baikalite also seem to occur in 

 veins, where they are accompanied by rhombohedral Lime- 

 haloide. 



4. The imbedded varieties of Augite are found almost in 

 every kind of basalt, and those rocks which are allied to it. 

 The largest crystals occur near Aussig in Bohemia, but it 

 is met with besides in the Rhon and Vogel mountains in 

 Germany, in France and Italy, in Scotland and its Western 

 Isles, &c. ; granular Augite and Sahlite are chiefly obtained 

 from Arendal in Norway, and Sahla in Sweden ; Baikalite 

 from the mouth of the Sljumanka river that falls into lake 

 Baikal. Diopside is found in Piedmont, Fassaite in the 

 valley of Fassa in the Tyrol, and in the Bannat of Temes- 

 war, Omphazite in the Saualpe in Carinthia, and near Hof 

 in Bayreuth. The beautifully green varieties of granular 

 Actinolite occur in the Bacher mountain in Lower Stiria, 

 the crystallised Green-earth in the valley of Fassa in the 

 Tyrol. Pyroxene rock occurs in the Pyrenees ; among those 

 compound rocks, where it forms one of the constituents, 

 we shall notice here only the greenstone from the celebrat- 

 ed Meissner mountain in Hessia. That black mineral, 

 which is discernible in some meteoric stones, for instance 

 those which fell at Stannern in Moravia, likewise seems to 

 be paratomous Augite-spar. These meteoric stones, and 

 the above mentioned greenstone from Meissner, but for 

 the coarser grain of the latter, possess a high degree of re- 

 semblance to each other.
