My dear Sir
I am much obliged for your great kindness in having sent me your “Histoire des Sciences &c”.2 From what I see of the contents I look forward with real eagerness to read it; but I shall not be able to begin for a week or two. I have just published a small book on Expression, which I did not suppose you would care to see; but from the nature of your recent studies, parts may possibly interest you, so I have told my Publisher to send you a copy.3
My health keeps very weak & I dread the exertion of grappling with the fearful subject of variation; so I am now employed in working up some observations in Botanical physiology made twelve years ago, which I intend publishing with some other new matter & some of my old papers on Climbing Plants, Dimorphism &c in a volume.—4
With cordial thanks & sincere respect, Pray | believe me | Yours very faithfully | Charles Darwin
