I859-] RESTING AT ILKLEY. 529 



" not clear," or " ?." Such marks would cost you little trouble, 

 and I could copy them and reflect on them, and their value 

 would be infinite to me. 



My larger book will have to be wholly re- written, and not 

 merely the present volume expanded ; so that I want to waste 

 as little time over this volume as possible, if another edition

 year ago, that if ever I lived to see Lyell, yourself, and Hux- 

 ley come round, partly by my book, and partly by their own 

 reflections, I should feel that the subject is safe, and all the 

 world might rail, but that ultimately the theory of Natural
