286 PHYSIOGRAPHY. CLASS ii. 



Axinite, axotomous Triphane-spar, rhombohedral Quartz, 

 Asbestus, and various other minerals. Zoisite is found in 

 single crystals, and crystalline masses in beds with hemi- 

 prismatic Augite-spar, dodecahedral Garnet, rhombohedral 

 Quartz, prismatic Disthene-spar, &c., or it constitutes beds 

 itself with prismatic Feld-spar, as in the Saualpe in Carin- 

 thia, where it forms the repository of pyramidal Zircon. 

 A reddish-white variety, consisting often of impalpable 

 particles of composition, is found in the Radelgraben in 

 Carinthia, along with prismatic Talc-mica, in primitive 

 mountains. 



4. Magnificent crystals of the present species are found 

 at Arendal in Norway ; and the name of Arendalite has been 

 given to these varieties, from their locality. Similar va- 

 rieties occur also in Sweden. Very fine crystallised va- 

 rieties are known from Switzerland, Piedmont, also from 

 the Pyrenees and the Upper Palatinate, in which localities 

 they occur in veins. Less distinct varieties of the Pista- 

 zite occur in many countries, as, for instance, in the Sau- 

 alpe, where certain varieties are found, which, by their 

 colour, connect the Pistazite with the grey varieties of 

 Zoisite. Beside's this locality, .Zoisite is also found in the 

 Bacher mountain and Schwamberg Alpe in Lower Stiria, in 

 the Fichtelgebiirge, and in the Tyrol. The red mangane- 

 sian varieties occur at St Marcel in the valley of Aosta in 

 Piedmont.
