ORDEft VI. HEMI-PRISMATIC AUGITE-SPAR. 281 



in gneiss, consisting of rhombohedral Quartz, dodecahedral 

 Garnet, prismatoidal Augite-spar, &c. ; Calamite in serpen- 

 tine, along with imbedded crystals of rhombohedral Lime- 

 haloide and octahedral Iron-ore. 



4. Basaltic Hornblende occurs in great abundance, and 

 in beautiful crystals, near Teising and Teplitz in Bohemia, 

 in large cleavable masses also, though not in regular crys- 

 tals, at Toplitza in Transylvania. Large and very distinct 

 crystals of a black colour are found imbedded in granular 

 limestone in Pargas in Finland. Crystals of common horn- 

 blende are met with at Arendal and other places in Nor* 

 way and in Sweden ; also imbedded in limestone, and of a 

 green colour, at Pargas in Finland, from whence the name 

 of Pargastte is derived. The crystals in the drusy cavities 

 of the Vesuvian minerals, though small, are generally very 

 distinct, and possess a high degree of lustre. Common 

 Hornblende occurs massive at Breitenbrunn, Ehrenfrie- 

 dersdorf, and other places in Saxony ; also in the Saualpe 

 in Carinthia, &c. Here also the most distinct varieties of 

 Carinthine have been found ; but at the same time perfect 

 transitions into common Hornblende. Calamite has been 

 discovered at Xormarken in Sweden. Many varieties of 

 Actinolite are met with in Salzburg and the Tyrol, granu- 

 lar Actinolite in the Bacher mountain in Lower Stiria, 

 asbestous Actinolite at Breitenbrunn, Raschau, and Ehren- 

 friedersdorf in Saxony. Common and glassy Tremolite occur 

 at St Gothard, at Sebes in Transylvania, &c. always in granu- 

 lar limestone or dolomite, asbestous Tremolite in Switzer- 

 land, the Tyrol, the Bannat, at Langefeld in Saxony, and 

 other places. Amiantus is found in great profusion in Corsi- 

 ca, also in Piedmont, Savoy, Salzburg, and Tyrol, in Upper 

 Hungary, and Silesia ; at Zoblitz and Waldheim in Sax- 

 ony, where in some places there is also common Asbestus. 

 Rock wood is still confined to Sterzing in the Tyrol, where 

 it occurs in large masses in a metalliferous bed, often mixed 

 with hexahedral Lead-glance. Rock Cork is found at 

 Johanngeorgenstadt in Saxony, at Sahlberg in Sweden, in 

 Moravia, Switzerland, and Spain, also at Portsoy, Lead-
