FINITE. 139 



Various localities are quoted for the common Asbestus ; 

 but since Asbestus contains also varieties of hemi-prismatic 

 and of paratomous Augite-spar, they cannot all be supposed 

 exact, and it would therefore be very interesting to institute 

 a closer natural-historical examination of all these minerals. 

 Among the localities chiefly quoted, are Zoblitz in Saxony, 

 Silesia, the Tyrol, and many other countries along the line 

 of the Alps, the Shetland isles, Portsoy, &c. where it oc- 

 curs in veins traversing serpentine ; in the Taberg and other 

 places in Sweden, where it occurs in beds, along with octa- 

 hedral Iron-ore, with several species of Pyrites, rhombo- 

 hedral and macrotypous Lime-haloide, &c.
