If you had not told me I should have thought that they had been added by someone else. As you expected, I differ grievously from you, and I am very sorry for it. I can see no necessity for calling in an additional and proximate cause in regard to Man. But the subject is too long for a letter. I have been particularly glad to read your discussion, because I am now writing and thinking much about Man. I hope that your Malay book sells well. I was extremely pleased with the article in the _Q.J. of Science_, inasmuch as it is thoroughly appreciative of your work. Alas! you will probably agree with what the writer says about the uses of the bamboo. I hear that there is also a good article in the _Saturday Review_, but have heard nothing more about it.--Believe me, my dear Wallace, yours ever sincerely, CH. DARWIN. P.S.--I have had a baddish fall, my horse partly rolling over me; but I am getting rapidly well. * * * * * _9 St. Mark's Crescent, N.W. April 18, 1869._ Dear Darwin,--I am very glad you think I have done justice to Lyell, and have also well "exposed" (as a Frenchman would say) Natural Selection. There is nothing I like better than writing a little account of it, and trying to make it clear to the meanest capacity. The "Croll" question is awfully difficult. I had gone into it more fully, but the Editor made me cut out eight pages. I am very sorry indeed to hear of your accident, but trust you will soon recover and that it will leave no bad effects. I can quite comprehend your feelings with regard to my "unscientific" opinions as to Man, because a few years back I should myself have looked at them as equally wild and uncalled for. I shall look with extreme interest for what you are writing on Man, and shall give full weight to any explanations you can give of his probable origin. My opinions on the subject have been modified solely by the consideration of a series of remarkable phenomena, physical and mental, which I have now had every opportunity of fully testing, and which demonstrate the existence of forces and influences not yet recognised by science. This will, I know, seem to you like some mental hallucination, but as I can assure you from personal communication with them, that Robert Chambers, Dr. Norris of Birmingham, the well-known physiologist, and C.F. Varley, the well-known electrician, who have all investigated the subject for years, agree with me both as to the facts and as to the main inferences to be drawn from them, I am in hopes that you will suspend your judgment for a time till we exhibit some corroborative symptoms of insanity. In the meantime I can console you by the assurance that I _don't_ agree with the _Q.J. of Science_ about bamboo, and that I see no cause to modify any of my opinions expressed in my article on the "Reign of Law."--Believe me yours very faithfully, ALFRED R. WALLACE. * * * * *
