I remain, yours very faithfully, CH. DARWIN.

CHARLES DARWIN TO A.R. WALLACE. Down, April 20 [1870].

My dear Wallace,

I have just received your book, and read the preface. There never has been passed on me, or indeed on any one, a higher eulogium than yours. I wish that I fully deserved it. Your modesty and candour are very far from new to me. I hope it is a satisfaction to you to reflect—and very few things in my life have been more satisfactory to me—that we have never felt any jealousy towards each other, though in one sense rivals. I believe that I can say this of myself with truth, and I am absolutely sure that it is true of you.

You have been a good Christian to give a list of your additions, for I want much to read them, and I should hardly have had time just at present to have gone through all your articles. Of course I shall immediately read those that are new or greatly altered, and I will endeavour to be as honest as can reasonably be expected. Your book looks remarkably well got up.

Believe me, my dear Wallace, to remain, Yours very cordially, CH. DARWIN.

CHARLES DARWIN TO A. GUNTHER. (Dr. Gunther, Keeper of Zoology in the British Museum.) March 23, [1870?].

Dear Gunther,
