HORNBLENDE SCHIST. 311 



The aspect of these varieties is so different

F. Common hornblende schist with interspersed

 felspar. 



This, like the former, has a very remarkable 

 appearance. It occurs in lona, as the former do 

 on the west coast of Ross-shire. 



G. Hornblende with mica; the former is in ex- 

 cess and the rock fissile. 



Mixtures of micaceous schist and hornblende

 of micaceous schist. 



H. Hornblende and chlorite intermixed. 



This is also enumerated under the head of 

 chlorite schist. 



I. Hornblende and actinolite. 



This passes into actinolite schist. The dis- 

 tinction between these two minerals is not
