From A. R. Wallace [27 September 1857]
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.
