OF THE SOUTH DEVON COAST. OF 
former existence of Archean mountain land over the area now 
occupied by the Channel. 
Dr. Hicks objected to Prof. Hughes’s view that schistose rocks 
such as those exhibited alternate with the granitoid series. He 
agreed with the author in referring the Devonshire rocks to the 
newer of the Archean series. The same succession had been de- 
seribed by Barrois in the North of Spain. 
Tur AvrHor agreed with Mr. Starkie Gardner that many of the 
materials of the Eocene and also of the Mesozoic rocks were derived 
from granitoid materials. In reply to Mr. Whidborne he stated that 
the rocks dredged by Mr. Hunt in the Channel were generally of a 
much older type than those of South Devon. The so-called 
gneiss near Prawle Point did not resemble any rock at the Lizard. 
In reply to Prof. Hughes he stated that he had never seen 
schists of the type now described by him alternating with granitoid 
rock, and that the two varieties of rock in South Devon, so much 
alike to the eye, yet really so different, formed a good parallel to 
the cases in Anglesey which had so misled Prof. Hughes.
