CHAPTER 1.III.--EVOLUTION, 1859-1863.

LETTER 71. TO A.R. WALLACE. Down, April 6th, 1859.

I this morning received your pleasant and friendly note of November
30th. The first part of my MS. is in Murray's hands to see if he likes
to publish it. There is no preface, but a short introduction, which
must be read by every one who reads my book. The second paragraph in the
introduction (71/1. "Origin of Species," Edition I., 1859, pages 1 and
2.) I have had copied verbatim from my foul copy, and you will, I hope,
think that I have fairly noticed your paper in the "Linn. Journal."
(71/2. "On the Tendency of Species to form Varieties, and on the
Perpetuation of Varieties and Species by Natural Means of Selection." By
Charles Darwin and Alfred Russell Wallace. Communicated by Sir Charles
Lyell and J.D. Hooker. "Journ. Linn. Soc." Volume III., page 45, 1859.
(Read July 1st, 1858.)) You must remember that I am now publishing only
an abstract, and I give no references. I shall, of course, allude to
your paper on distribution (71/3. "On the Law which has regulated the
Introduction of New Species" (A.R. Wallace). "Ann. Mag. Nat. Hist."
Volume XVI., page 184, 1855. The law alluded to is thus stated by
Wallace: "Every species has come into existence coincident both in space
and time with a pre-existing closely allied species" (loc. cit., page
186).); and I have added that I know from correspondence that your
explanation of your law is the same as that which I offer. You are
right, that I came to the conclusion that selection was the principle
of change from the study of domesticated productions; and then, reading
Malthus, I saw at once how to apply this principle. Geographical
distribution and geological relations of extinct to recent inhabitants
of South America first led me to the subject: especially the case of
the Galapagos Islands. I hope to go to press in the early part of next
month. It will be a small volume of about five hundred pages or so. I
will of course send you a copy. I forget whether I told you that Hooker,
who is our best British botanist and perhaps the best in the world, is a
full convert, and is now going immediately to publish his confession
of faith; and I expect daily to see proof-sheets. (71/4. "The Flora of
Australia, etc., an Introductory Essay to the Flora of Tasmania." London
