Discussion. 



Dr. Marr said that he had been over mucli of the ground with 

 the Author, and desired to express his admiration of the thorough 

 way in which the work had been done. The fact that towards the 

 end of his investigations the Author was able to view a section 

 which he had not previously visited, and, after a very brief 

 inspection, could state what was to be found there, was a proof 

 of the accuracy of the work. The speaker was interested in the 

 beds at Pinskey Gill. According to the Geological Survey map, 

 the conglomerate apparently overlying the 8j)irifera-\)Q?ccui% beds 

 was the ' Basal Conglomerate ' faulted into that place. The Author 

 suggested a different interpretation : the Devonian age of those beds 

 was suggested, but not stated. It need not be assumed that because 

 no Devonian strata had hitherto been recorded in the area, they 

 must necessarily be absent. Lastly, the speaker called attention 

 to the old view that the Lake District was an island in Lower 

 Carboniferous times ; he thought that the evidence brought forward 

 in the paper was against that view.
