To J. Croll. 



Down, Sept. 19th, 1S68. 



I hope that you will allow me to thank you for sendin 

 mc your papers in the Phil. Magazine} I have never, I 

 think, in my life been so deeply interested by any geological 

 discussion. I now fust begin to see what a million mean , 

 and 1 feel quite ashamed of myself at the silly way in which 

 I have spoken of millions of years. I was formerly a great 

 believer in the power of the sea in denudation, and this was 

 perhaps natural, as must of my geological work was done 

 near sea-coasts and on islands. Hut it is a consolation to 

 me to reflect that as soon as I read Mr. Whittaker's paper 8 

 on the escarpments of England, and Ramsay 3 and Jukes' 1 

 papers, I gave up in my own mind the case ; but I never 

 fully realised the truth until reading your papers just 

 received. How often 1 have speculated in vain on the origin 

 of the valleys in the chalk platform round this place, but now 

 all is clear. I thank you cordially for having cleared so 

 much mist from before my eyes.
