My dear Mr. Lubbock — I shall have great pleasure 

 in proposing you as a member of the Geological Society. 



I am glad to hear of more fossil bones being found at 

 Green Street Green, for I was sorry not to be able to see 

 the exact bed when with you, owing to the removal of 

 some of the deposit which contained the bones. 



Last week I examined with Mr. Prestwich the valleys 

 of the Chalk between Henley on Thames and the 

 escarpment of the chalk which overlooks the Vale of 

 Oxfordshire. They are counterparts of the valleys 

 between you at High Elms and the escarpment at
