(1) On a Continuous Succession in part of the Guernsey 

 Gneiss. By Rev. E. Hill, MA. 



In the discussion which followed a paper c on the Rocks of 

 Guernsey ' read by me before the Geological Society it was sug- 

 gested by one of the speakers that appearances in Archaean rocks of 

 conformable succession and enormous thickness are often deceptive, 

 and result from repeated plications of a moderately thick series. 

 I have no doubt that this remark is correct, and it is perfectly 

 possible that such plications may have happened in Guernsey, and 

 may hereafter by careful examination be detected. But notwith- 

 standing there cannot be any doubt that the Guernsey rocks do 

 disclose a series of very great thickness. 



While making a specially careful examination of a locality in 

 Guernsey in search of evidence for or against the faulted position 

 of certain unusual rocks, I began to notice that particular varie- 

 ties of the gneiss could be recognized at various localities as 

 agreeing together. In some of the outcrops a distinct strike of
