1 CHLORITE SCHIST. 



ALTHOUGH chlorite schist does not, like the 

 preceding rocks, form any extensive tracts in na- 

 ture, as far as the observations of geologists have 

 yet extended, and although its characters are not 

 in all cases very definite, it is sufficiently distinct 

 Yrom micaceous schist in many points, and suffi- 

 ciently remarkable with respect to some of its 

 connexions, to require a separate place in a clas- 

 sification like the present. 



As it has not hitherto obtained such a place in 

 the only geological arrangements of rockfe which 

 have been published, and as it also appears to 

 have received but a small degree of attention 

 from geological writers, the observations which 

 relate to it are drawn solely from the appearances 

 which it presents in Scotland. 



Its predominant association is with micaceous 

 schist, into which it passes, in so gradual a man- 

 ner, that different observers rarely coincide in
