I have been pretty well since my return from Wales, though at the time it did me no good.
We shall be in London next month, when I shall hope to see you.—My dear Wallace, yours very sincerely,
CH. DARWIN.
9 St. Mark's Crescent, N.W. December 4, [1869].
Dear Darwin,—Dr. Adolf Bernhard Meyer, who translated my book into German, has written to me for permission to translate my original paper in the Linnean Proceedings with yours, and wants to put my photograph and yours in it. If you have given him permission to translate the papers (which I suppose he can do without permission if he pleases), I write to ask which of your photographs you would wish to represent you in Germany—the last, or the previous one by Ernest Edwards, which I think much the best—as if you like I will undertake to order them and save you any more trouble about it. It is, of course, out of the question our meeting to be photographed together, as Mr. Meyer coolly proposes.
Hoping you are well, believe me yours very faithfully,
ALFRED R. WALLACE.
P.S.—I have written a paper on Geological Time, which will appear in Nature, and I think I have hit upon a solution of your greatest difficulties in that matter.—A.R.W.
