from yours. But I do not consider my conclusions 

 yet conclusive, nor do I yours, nor Talbot's, and he 

 knows more about it than any of us. However, we 

 are in a fair way. Lists, Lists, Lists, are what we 

 want, and what you want, and without lists the fight is

 unconformities I say nothing, and wink my mental eye. 

 Therefore let us have lists. I shall be up in a week

 central Scotland, mentioning localities that had never 

 been cited before ; who could refer to places all over 

 Wales from Anglesey to Pembrokeshire, some of which 

 no geologist out of the Survey had ever visited ; who 

 knew Charnwood Forest, had rambled across Shrop- 

 shire, Cheshire, Staffordshire, and Derbyshire, had
