a system of faults running through by Wind's Point, throwing 

 down the volcanic series to the east and south, and causing the 

 advance of the gneissic series towards the Severn Yalley in front of 

 Wind's Point. 



Prof. Watts pointed out that in the Lickey Hills some of the 

 rhyolites and rhyolitic ashes were so much impregnated with 

 carbonate of lime that they might be easily mistaken for lime- 

 stone. 



Prof. BoNNEr expressed his sense of the value of the paper, for 

 the subject was one so difficult that only a resident could adequately 

 deal with it. He thought that the carbonate of lime might have 

 filtered down from Silurian limestones that had been subsequently 

 removed by denudation. He was disposed to regard the rocks 

 described by the Author as considerably later than the Malvernian 

 crystallines, though yet Archaean. He might mention that traces of 

 rhyolitic rocks had been found by his friend Mr. Coles in grits 

 on the Abberley Hills. 



The President and Mr. H. H. Arnold-Bemrose also spoke. 



The Author thanked the Society for their kind reception of his 

 paper. He said that the presence of the lime might be explained on 

 the supposition that the area was at one time overlain by the 

 Silurian rocks. He had in his possession a Favosites which had 

 been found just below the filter-beds.
