Saw at Mr Bell's at Hornsey the offspring of a black & white duck of pecu drake with the penguin duck. it took after the Penguin in the form of its body & in the manner of walking but not waddling; its colour was darker than the penguin & the bright feathers on its wing resembled the drake. — another of same half breed resembled the plumage of drake still more. — So Penguin impresses its form both on vars & species

The Echnida & Hedgehog Tenrec both having spines, is the effect, partly of the same external conditions (ie. analogical structure) & partly the laws of organization (ie those laws which prevent infinite variation in every possible way. — the laws which determine the kinds of monstrosity, & determine the kind of variation & sporting in flowers & domestication of animals

When it is said that there is evidence in the organic world of infinite & growing complexity from a few types, it must not be supposed that this refers to time. — Marsupial in Oolite. — insects, of do orders — cheiroptera & cætacea in Eocene — dicot. plants in coal measures. — Shells in Cambrian & Crust show how long since present forms existed, but if it be asked how this complexity from a few types originated, we must go to the first origin of the world. — our present organic beings are the descendants, slightly a good deal modified & Many Forms lost; if of this old stock (which from action & reaction grew more complex) some perhaps rendered more complex & some simplified. —

I presume, from my theory, as long as any structure can be handed down without being absolutely injurious (or requiring nutrition) to a certain amount it will be so handed down (. as mammae of men callosities on Camels & Horses —. —) & therefore probably any structure would rather become accomodated to new circumstances than it would be eliminated, & hence, the application of structure to purpose after purpose would tend to render complex the series. —

Sept 31. The identity of (or only closeness) of some species — (especially of mammifers) in old beds & existing species is valuable because it shows no innate power of change & it also shows, what enormous changes of conditions, some species will undergo & yet remain adapted. — it does away with difficulty of rabbits of England remaining same (if so) with those of Spain & such facts — This unequal duration is exactly same as some species extending much further geographically than others.

Hensleigh objects to transmut. theory, on the grounds of similarity in condition in Java & Sumatra & dissimilarity of forms — yet how valueless this objection, when one thinks of different kinds of cattle in every part of England. &c &c

NB. In botanical geography, there can be no sharp division of partition as between Mammalia in cases such as that of Java & Sumatra

Waterhouse showed me the component vertebræ of the head of Snake wonderful!! distinct!! — He would not allow such series showed passages — yet in talking, constantly said as the brain spinal marrow expands, so do the bones are created expand — instead of saying as brain is created &c &c
Bats are a great difficulty not only are no animals known with an intermediate structure, but it is not possible to imagine what habits an animal could have had with such structure. — perhaps greatest

Could anyone. have foreseen, sailing, climbing & mud-walking fish?

57

difficult — yet suggested. (vipers tooth also a difficult), the whole mind is constituted that a difficulty makes greater impression, than the grouping of many facts with laws & their explanation will probably reject this theory — (I must answer it by rooting out curious cases of intermediate structure, & supposing much extinction. give a parallel case)
Waterhouse remarked, that any argument for transmut, from one organ graduating into other is lost, be (as vertebræ into skull, two bones of tibia into one. —) because if the animals were taken from which these series were drawn they would not be intermediate, but this is not required. —

Waterhouse says perhaps animals of Fernando Noronha are found on unknown coast in front of it. —

Cuvier has grand sentence about the Animaux fossiles — being a mere fragment of the discoveries to come — Owen in his description of my fossils makes same such remark & before the conclusion of his work — Lund makes his wonderful discoveries = negative facts are valueless = monkeys =

64 [blank]

65

Owen has described a greatt Struthonidous Bird from New Zealand — so not an Apteryx, yet it shows the Apteryx is not quite isolated in its present locality — there have been at least other birds, with small wings, & surely the Apteryx is more closely allied to the Struthonidae than any other forms —

In S. America. it appears from Lund more Mammals, than at present
in Europe we know there has been several successions of Mammals. —
yet only two monkeys, there are now have been found fossil in S. America, there are now — — species in S. America. — so see what a mere vestige, is preserved in this country — same argument to India & Europe — & Africa!, — any negative argument against — monkey-man, valueless. —
May not several generations have been confounded in the caves?
It is highly important, to bear in mind that enormous periods may elapse, even in situations apparently favourable for the preservation of shells; where land broken, rivers entering. — & yet no shells — now look

80

at Scotland — coasts of Chile, excepting Concepcion — Patagonia — Beds of La Plata. (except close to B. Ayres). — If we may take this as guide, the shells preserved must be as much a casualty as, bones of Mammalia in caves: — argue first case of bones (New Red Sandstone) & then go on to shells —

81

A profound consideration of method by which races of men have been exterminated (see Pritchards paper) (Ed. Phil. Journ. end of 1839) very important. it seems owing to immigration of other races, so it is with domestic breeds. (though in this case crossing has had somewhat to do with it. mem. dogs & pigs in Polynesia; & dogs in S. America Rengger.
— now it is this very immigration which tends to make the destroyers vary; so that we here see reasons — why no perfect gradation can be expected in any one country. — in a descending series of strata
This again shows how much forms depend on other forms

Maer June /41/, observed 3 plants of Caltha Palustris alone together. one had seed-pods turning brown, whilst both others were in nearly full flower

Maer June /41/
Rhododendrum — nectary marked by orange freckles on upper petal; bees & flies seen directed to it — The Humbles in crawling out brush over anther & pistil & one I saw impregnate by pollen with which bees a bee was dusted over.
[sketch]
Stamens & pistils have curve upwards, so that anthers & stigma lie in fairway to nectary. — Is not this so in Kidney Bean. How is it generally. —
In Azalea do it is so
Though I saw no Bees several visiting it. — In yellow day lily, the Bees visit base of upper petal, though not differently coloured — & stamens bend up a little

94

[page found in CUL-DAR49.22]

In a wild purple Geranium, I see Bees visit always base of (a) upper petal from facility of alighting? which is not differently coloured & to which stamen & pistils have no relation. In Monk's Hood, a bee entering long nectary, would necessary cross directly over the bunch of anthers & pistils, but these do do not bend up — In Lark-spur, if Bees put proboscis within nectary they do they must disturb all anthers, wh otherwise lie protected by the hairy black lip of lower division of nectary: wh. itself resembles a Bee, but does not prevent bees visiting it. In Columbine nectaries are placed all round flower as they are in Crown-Imperial Lily & many other flowers —

95

My view of variety acquired character of characters being inherited at corresponing age & sex, opposed by cantering horses having colts which can canter — & dogs trained to pursuit having puppies with the same powers instinctive & doubtless not confined to sex. — Is not cantering a congenital peculiarity improved. Probably every such new quality becomes associated with some other, as pointing with smell. = These qualities have been given to fœtus fr before sex developed — Double flowers & colours breaking only hereditary characters, wh. come on in

96

after life of Plants — also goodness of flavour in fruit — all affected by cultivation during life of individual.

June 1st 1841. Maer Examined the Lemon-thyme. — equally abortive as it was in autumn: filaments united in whole length to corolla —anthers minute, distinctly doubled, brown, but with no pollen. — Common Thyme growing close by is equally abortive —and both growing within Kitchen Garden. — As we see in Hybrids that although anther nor filaments shrivel, yet stigma does not, so we may feel somewhat but little less surprised at Henslow's remark that pistil does not become abortive.

100

[page now in CUL-DAR109.16]

Examined in microscope — some of the stigmas of [sketch] shape of ordinary Labiatæ —the chief part with ordinary divisions, & a few with one lobe again divided Have dried some. — some with no division in young flowers. The abortive stamen are of useful height. —

103

[page now in CUL-DAR77.62]

In Lupine, Bees frequent & seem to act, something like on Kidney Bean, they go to nectar at foot of upper petal standing on
I saw Bee go to two species of Lupine,
two wings. & when the Lupine flower is perfectly ripe & pollen abundant filaments & stamens all protrude there is a brush at end of stigma, which forces out from extremity pollen, or pollen comes out with anthers & stigma in slit — As I think they do in Broom & certainly when over-ripe & half withered — I saw Bees going to clover & once this happened. — (a) And in common Beans it is wonderful how the Humbles force down the wings most violently: in Beans the wings seem beautifully to protect sheath

104

[page now in CUL-DAR77.62]

In all these nectar seems to be at base of upper petal & the curvature of an pistil, &c lies in gangway = In Lotus corniculatus saw Humble press down wings which ejects pollen from tip of sheath. — Also in Lathyrus pratensis yellow saw stigma project In common Pea saw Humble so press down sheath, that stigma covered with pollen was pressed & rubbed along whole breast — pressing either one or both of Pea's wings, stigma & mass of yellow pollen protrudes at sheath. — At last I saw Bee collecting pollen from sheath Keel of Lupine —
Seen Bees on Potato &c several times on Beans

Rough. — green-cabbage in flower — swarmed with meligethes & small Staphylinidæ on all their bodies pollen — on a sulphur Broccoli not many do — pollen not very abundant. not very small — Saw one small Bee; saw another on Cabbage — white Butterflies suck nectar:
Maer June 41
Rhubarb. pollen very minute — not excessively abundant flowers not attractive, very small — stigma rather large & rough — flowers common — many winged thrips, covered with pollen — Thrips about as large as bit of chopped horse hair with legs & take flight — Yet we have crosses — I see Bees almost

Saw Humble go from great Scarlet Poppy to Rhododendron — from Larkspur to Lupine two species of Larkspur — two varieties of Cistus Speedwell to Rhododendron — Loasa Anchusa — speedwell Iris — Azalea. Rhodendron. Fraxinella to Anchusa never once
P on Fraxinella Heartease small. Humble alighted on base of filaments & reached nectar = again = between them, hence quite below stigma. & so avoided it.
On certain days Humble seem to frequent certain flowers, to day early, the great scarlet Poppy —

112

[page now in CUL-DAR46.2(ser.3).5]

So that, finally Fraxinella. with respect to nectary is same case as Azalea or Rhododendron

[sketch]

xx after several gloomy days. hot one, Bees almost P every minute to Fraxinella & from flower plant to plant. — to my grt surprise — I found all, stamens straightened pollen profusely shed; lengthened &turned up more than stamens, so that all were brushed by Bees & especially stigma after bee had brushed over the anthers of long stamens
as stamens grow old & shed some pollen. they turn upwards & bend over stigma: — but stigma is almost roofed by united filaments. —
This flower hostile to intermarriage!! xx

Saw Bees frequent these flowers till late in evening — On rough calc. 280 flowers — allowing each Bee visits 10 flowers in minute
each flower will be visited in 28 minutes — say then each flower is visited 30 times a day is considerably under mark, & this has now gone on 14 days. (except some wet ones/ & wd go on longer —
