5] and writing a criticism of it, and of Galton, who backs him up with his idea of "organic stability." ... Neither he nor Galton appears to have any adequate conception of what Natural Selection is, or how impossible it is to escape from it. They seem to think that, given a stable variation, Natural Selection must hide its diminished head! Bateson's preface, concluding reflections, etc., are often quite amusing.... He is so cocksure he has made a great discovery--which is the most palpable of mare's nests.--Yours very truly, ALFRED R. WALLACE. P.S.--I allude of course to his grand argument--"environment _continuous_--species _discontinuous_--therefore _variations_ which produce species must be also _discontinuous_"! (Bateson--Q.E.D.). * * * * * TO PROF. POULTON _Parkstone, Dorset. February 19, 1895._ My dear Poulton,--I have read your paper on "Theories of Evolution"[26] with great pleasure. It is very clear and very forcible, and I should think must have opened the eyes of some of your hearers. Your cases against Lamarckism were very strong, and I think quite conclusive. There is one, however, which seems to me weak--that about the claws of lobsters and the tails of lizards moving and acting when detached from the body. It may be argued, fairly, that this is only an incidental result of the extreme muscular irritability and contractibility of the organs, which might have been caused on Lamarckian as well as on the Darwinian hypothesis. The running of a fowl after its head is chopped off is an example of the same kind of thing, and this is certainly not useful. The detachment itself of claw and tail is no doubt useful and adaptive. When discussing the objection as to failures not being found fossil, there are two additional arguments to those you adduce: (1) Every failure has been, first, a success, or it could not have come into existence (as a species); and (2) the hosts of huge and very specialised animals everywhere recently extinct are clearly failures. They were successes as long as the struggle was with animal competitors only, physical conditions being highly favourable. But, when physical conditions became adverse, as by drought, cold, etc., they failed and became extinct. The entrance of new enemies from another area might equally render them failures. As to your question about myself and Darwin, I had met him once only for a few minutes at the British Museu
