MODE XIV. S1DEROMAGNESIAN ROCKS. ] 25) 



Stiria, Tyrol, Scotland, &c. It is generally sprin- 

 kled with octaedral crystals of iron, and some- 

 times with garnets. The first are the most cha- 

 racteristic of this rock. 



Chlorite slate, mixed with quartz. This kind 

 is commonly even schistose, but far more hard 

 than the former. 



Saussure, 2264, expresses great surprise, 

 when, on receiving specimens of the chlorite slate 

 of Werner, he observed that there was scarcely 

 any chlorite in them ; and he adds, that the de- 

 nomination being quite deceitful, it ought to be 

 changed. 



On the lofty summit called the Col du Geant, 

 Saussure found that the granite, like that which 

 is greatly elevated at Mont Blanc, can scarcely be 

 said to contain mica. Here its place was often 

 supplied by a small-grained chlorite*. 



STRUCTURE II. ACTINOTE. 



This substance also chiefly occurs in small por- 

 tions. It is the strahlstein of the Germans, and is 

 by Werner divided into the asbestoid, the com- 

 mon, and the glassy. Of these it is believed the Glass y 



actmote.
