14 PUBLICATION OF THE 'ORIGIN OF SPECIES.' [1859. 



detailed and lengthy criticisms, but merely a few general 

 remarks, pointing out the weakest parts. 



If you are in even so slight a degree staggered (which I 

 hardly expect) on the immutability of species, then I am 

 convinced with further reflection you will become more and 

 more staggered, for this has been the process through which 

 my mind has gone. My dear Henslow, 



Yours affectionately and gratefully, 



C. Darwin. 



C. Darwin to John Lubbock* 



Ilkley, Yorkshire, 

 Saturday [November 12th, 1859]. 



. . . Thank you much for asking me to Brighton. I hope 

 much that you will enjoy your holiday. I have told Murray 

 to send a copy for you to Mansion House Street, and I am 

 surprised that you have not received it. There are so many 

 valid and weighty arguments against my notions, that you, 

 or any one, if you wish on the other side, will easily persuade 

 yourself that I am wholly in error, and no doubt I am in part 

 in error, perhaps wholly so, though I cannot see the' blindness 

 of my ways. I dare say when thunder and lightning were 

 first proved to be due to secondary causes, some regretted to 

 give up the idea that each flash was caused by the direct 

 hand of God. 



Farewell, I am feeling very unwell to-day, so no more. 



Yours very truly, 



C. Darwin. 



C. Darwin to John Lubbock. 



Ilkley, Yorkshire, 

 Tuesday [November 15th, 1859]. 



My dear Lubbock, — I beg pardon for troubling you 

 again. I do not know how I blundered in expressing myself 

 in making you believe that we accepted your kind invitation 



* The present Sir John Lubbock.
