1859.] PLANS FOR PUBLICATION. 507 



My Abstract will be about five hundred pages of the size 

 of your first edition of the ' Elements of Geology.' 



Pray forgive me troubling you with the above queries ; 

 and you shall have no more trouble on the subject. I hope 

 the world goes well with you, and that you are getting on 

 with your various works. 



I am working very hard for me, and long to finish and be 

 free and try to recover some health. 



My dear Lyell, ever yours, 



C. Darwin. 



Very sincere thanks to you for standing my proxy for the 

 Wollaston Medal. 



P. S. Would you advise me to tell Murray that my book 

 is not more #/z-orthodox than the subject makes inevitable. 

 That I do not discuss the origin of man. That I do not bring 

 in any discussion about Genesis, &c, &c, and only give facts, 

 and such conclusions from them as seem to me fair. 



Or had I better say nothing to Murray, and assume that 

 he cannot object to this much unorthodoxy, which in fact is 

 not more than any Geological Treatise which runs slap 

 counter to Genesis.
