DCP-LETT-2145

From:
Alfred Russel Wallace
To:
Charles Robert Darwin
Date:
[27 Sept 1857]
Source of text:
DAR 47: 145
Summary:

Refers to CD’s letter of "May last". ARW’s views on order of succession of species are in accordance with CD’s.

Disappointed that his paper ["On the law which has regulated the introduction of new species", Ann. & Mag. Nat. Hist. 2d ser. 16 (1855): 184–96] elicited no discussion; now ARW is trying to prove it. Paper merely states the theory.

On black jaguars breeding inter se: ARW has never heard of a parti-coloured one.
