To François Jules Pictet de la Rive 11 November 
Down Bromley, Kent [Ilkley]
I have taken the liberty to send you, as a mark of my respect, a copy of my work (as yet only an abstract) on the Origin of Species.— As it is evident from your great work on Palæontology1 that you have profoundly reflected on this subject,2 I have thought that you might perhaps like to read my book, which I venture to assure you is the result of long-continued & conscientious labour.— I beg you not to think me so presumptuous as to suppose that my work will alter your general conclusions; but it may possibly lead you to reflect further on the side opposed to your view. If you should be induced to read my volume, I venture to state, that it is so much condensed, that it will not be intelligible, unless it be read straight through.—
With much respect & with apologies for troubling you with this note, which does not require any answer, I have the honour to remain | Sir | Your faithful servant | Charles Darwin
Sending copy of Origin; "it may possibly lead you to reflect further on the side opposed to your view".
