LETTER 102. TO C. LYELL. Down, May 22nd [1860].

Hooker has sent me a letter of Thwaites (102/1. See Letter 97.), of Ceylon, who makes exactly the same objections which you did at first about the necessity of all forms advancing, and therefore the difficulty of simple forms still existing. There was no worse omission than this in my book, and I had the discussion all ready.

I am extremely glad to hear that you intend adding new arguments about the imperfection of the Geological Record. I always feel this acutely, and am surprised that such men as Ramsay and Jukes do not feel it more.

I quite agree on insufficient evidence about mummy wheat. (102/2. See notes appended to a letter to Lyell, September 1843 (Botany).

When you can spare it, I should like (but out of mere curiosity) to see Binney on Coal marine marshes.

I once made Hooker very savage by saying that I believed the Coal plants grew in the sea, like mangroves. (102/3. See ”Life and Letters,” I., page 356.)

LETTER 103. TO J.D. HOOKER.

(103/1. This letter is of interest as containing a strong expression upon the overwhelming importance of selection.)

Down [1860].

Many thanks for Harvey's letter (103/2. W.H. Harvey had been corresponding with Sir J.D. Hooker on the ”Origin of Species.”), which I will keep a little longer and then return. I will write to him and try to make clear from a.n.a.logy of domestic productions the part which I believe selection has played. I have been reworking my pigeons and other domestic animals, and I am sure that any one is right in saying that selection is the efficient cause, though, as you truly say, variation is the base of all. Why I do not believe so much as you do in physical agencies is that I see in almost every organism (though far more clearly in animals than in plants) adaptation, and this except in rare instances, must, I should think, be due to selection.

Do not forget the Pyrola when in flower. (103/3. In a letter to Hooker, May 22nd, 1860, Darwin wrote: ”Have you Pyrola at Kew? if so, for heaven's sake observe the curvature of the pistil towards the gangway to the nectary.” The fact of the stigma in insect-visited flowers being so placed that the visitor must touch it on its way to the nectar, was a point which early attracted Darwin's attention and strongly impressed him.) My blessed little Scaevola has come into flower, and I will try artificial fertilisation on it.

I have looked over Harvey's letter, and have a.s.sumed (I hope rightly) that he could not object to knowing that you had forwarded it to me.

LETTER 104. TO ASA GRAY. Down, June 8th [1860].

I have to thank you for two notes, one through Hooker, and one with some letters to be posted, which was done. I antic.i.p.ated your request by making a few remarks on Owen's review. (104/1. ”The Edinburgh Review,”

April, 1860.) Hooker is so weary of reviews that I do not think you will get any hints from him. I have lately had many more ”kicks than halfpence.” A review in the last Dublin ”Nat. Hist. Review” is the most unfair thing which has appeared,--one ma.s.s of misrepresentation. It is evidently by Haughton, the geologist, chemist and mathematician.

It shows immeasurable conceit and contempt of all who are not mathematicians. He discusses bees' cells, and puts a series which I have never alluded to, and wholly ignores the intermediate comb of Melipona, which alone led me to my notions. The article is a curiosity of unfairness and arrogance; but, as he sneers at Malthus, I am content, for it is clear he cannot reason. He is a friend of Harvey, with whom I have had some correspondence. Your article has clearly, as he admits, influenced him. He admits to a certain extent Natural Selection, yet I am sure does not understand me. It is strange that very few do, and I am become quite convinced that I must be an extremely bad explainer. To recur for a moment to Owen: he grossly misrepresents and is very unfair to Huxley. You say that you think the article must be by a pupil of Owen; but no one fact tells so strongly against Owen, considering his former position at the College of Surgeons, as that he has never reared one pupil or follower. In the number just out of ”Fraser's Magazine”

(104/2. See ”Life and Letters,” II., page 314.) there is an article or review on Lamarck and me by W. Hopkins, the mathematician, who, like Haughton, despises the reasoning power of all naturalists. Personally he is extremely kind towards me; but he evidently in the following number means to blow me into atoms. He does not in the least appreciate the difference in my views and Lamarck's, as explaining adaptation, the principle of divergence, the increase of dominant groups, and the almost necessary extinction of the less dominant and smaller groups, etc.

LETTER 105. TO C. LYELL. Down, June 17th [1860].

One word more upon the Deification (105/1. ”If we confound 'Variation'

or 'Natural Selection' with such creational laws, we deify secondary causes or immeasurably exaggerate their influence” (Lyell, ”The Geological Evidences of the Antiquity of Man, with Remarks on Theories on the Origin of Species by Variation,” page 469, London, 1863). See Letter 131.) of Natural Selection: attributing so much weight to it does not exclude still more general laws, i.e. the ordering of the whole universe. I have said that Natural Selection is to the structure of organised beings what the human architect is to a building. The very existence of the human architect shows the existence of more general laws; but no one, in giving credit for a building to the human architect, thinks it necessary to refer to the laws by which man has appeared.

No astronomer, in showing how the movements of planets are due to gravity, thinks it necessary to say that the law of gravity was designed that the planets should pursue the courses which they pursue. I cannot believe that there is a bit more interference by the Creator in the construction of each species than in the course of the planets. It is only owing to Paley and Co., I believe, that this more special interference is thought necessary with living bodies. But we shall never agree, so do not trouble yourself to answer.

I should think your remarks were very just about mathematicians not being better enabled to judge of probabilities than other men of common-sense.

I have just got more returns about the gestation of hounds. The period differs at least from sixty-one to seventy-four days, just as I expected.

I was thinking of sending the ”Gardeners' Chronicle” to you, on account of a paper by me on the fertilisation of orchids by insects (105/2.

”Fertilisation of British Orchids by Insect Agency.” This article in the ”Gardeners' Chronicle” of June 9th, 1860, page 528, begins with a request that observations should be made on the manner of fertilisation in the bee-and in the fly-orchis.), as it involves a curious point, and as you cared about my paper on kidney beans; but as you are so busy, I will not.
