e Chronicle.") If so, and you
could get me a copy, I should like to have one.

Believe me, my dear Henslow, I feel grateful to you on this occasion,
and for the multitude of kindnesses you have done me from my earliest
days at Cambridge.

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 analogy 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 assumed (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 anticipated 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 mass 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
