My dear Darwin

Accept very best thanks for ‘Expression’ which I have been devouring¹   You will, I am sure, receive numberless letters of hints corroborative of the points you make,—even I could & will send some—² But I write especially to say that if you care to send any more printed circulars of queries I can dispose of three this very month most excellently for you   One by an expedition up the Congo, another by a man from the Zanzibar side into Africa and a third by a very intelligent German (English speaking) head of a missionary college, on his way to my old county in Africa.³

Would you have a short note sent me,—pray do not write yourself—about the rabbits.⁴

Ever sincerely yours | Francis Galton

PS. You do not I think mention in Expression what I thought was universal among blubbering children (when not trying to see if harm or help was coming out of the corner of one eye) of pressing the knuckles against the eyeballs; thereby reinforcing the orbicularis.⁵

What a curious custom hand-shaking is & how rapidly savages take to it, in their intercourse with Europeans.

I have a pamphlet of yours to send back
