THE BULLETIN OF THE BRITISH MUSEUM (NATURAL HISTORY), instituted in 1949, is issued in five series corresponding to the Departments of the Museum, and an Historical series.

Parts will appear at irregular intervals as they become ready. Volumes will contain about three or four hundred pages, and will not necessarily be completed within one calendar year.

In 1965 a separate supplementary series of longer papers was instituted, numbered serially for each Department.

This paper is Vol. 3, No. 5 of the Historical series. The abbreviated titles of periodicals cited follow those of the World List of Scientific Periodicals.

It was explained in the Introduction to Darwin's First Notebook on Transmutation of Species, that his method of working, when preparing to write his large book on Natural Selection which never appeared, but of which the Origin of Species was an abstract, was to cut out of his Notebooks those pages which contained the material of which he felt most in need. The result was that the Notebooks themselves were mutilated ; but it was found that, as they stood, they provided so much useful information on the way in which Darwin's thoughts flowed, and the dates on which he made certain notes, that they were published. About a year later, some of the excised pages were found, partly among papers which Sir Robin Darwin had deposited with the Science Museum and subsequently transferred temporarily to the British Museum (Natural History), and partly in the Museum's library. In this manner 28 pages were recovered, the notebooks to which they had belonged determined, transcribed, edited, and published.

On the death of Mr. Bernard Darwin, his son Sir Robin Darwin deposited temporarily at the Museum a box of papers in which were found 202 more of the missing pages, and these form the subject of the present publication. The number of pages still missing now stands at about 70, and of these some may have been blank. The probability of their being discovered is small, and it is probable that as much has been collected of Darwin's Notebooks on Transmutation of Species as ever will be : 824 pages.

These newly found pages were the ones which Darwin himself considered to be the most important for his work, and it would be impossible to comment on them. An exception must, however, be made, in drawing attention to the pages (III, 134 & 135) which make it possible to determine which passage it was in Malthus's Essay on the Principle of Population which provided Darwin with what he required to prove that natural selection forced favourable adaptive variants into their ecological

niches, to know the exact date when this struck him, and to read the immediate effect which this had in his mind and led him to draft his most striking definition of natural selection.

The different notebooks to which the pages originally belonged were identified by the late Mr. A. C. Townsend and one of us (B.M.S.) by comparing the scissor-marks on the pages and on the stumps left in the notebooks.

Darwin classified his excised pages and marked many of them with large figures scrawled in black or red pencil. A table of these is given.

The editorial policy adopted with the excised pages is the same as that used with the Notebooks, but simplified as much as possible. No attempt has been made at facsimile reproduction, and if a reader should require to know whether any particular word or phrase was written in ink or in pencil, and possibly at a later date than the body of the text, he must consult the original manuscript pages, which are now in the Cambridge University Library.

It is a pleasure to record indebtedness to Sir Robin Darwin, Mr. H. R. Creswick, Mr. P. J. Gautrey, and particularly to Dr. Sydney Smith who not only gave us the benefit of his Transcription of difficult readings of the text and pointed out many of our mistakes, but very kindly supplied us with the text of additional excised pages which he found in the Cambridge University Library.


N.B. Some pages are marked with more than one number. They are all referred to here by the Notebook in Roman figures, followed by the manuscript page number in arabic figures.

May this not be explained on principle of animal having come to island where it could increase, but there were causes to induce great change, like the Buzzard which has changed into Caracara at the Galapagos, law of chance would cause this to have happened in all but less in water birds.—|

It is interesting to note this early date at which Darwin was interested in the viability of seeds immersed in sea water, on which he made experiments twenty years later.

The intimate relation of Life with laws of chemical combination, & the universality of latter render spontaneous generation not improbable. |


Fraser53 remarked to me at Zoological Society, that you never find two similar groups of birds in two countries, without intermediate ones occurring in intermediate country — i.e. mundine groups. —

Waterhouse54 tells me in insects there are many plenty of instances of insects of one tribe taking on structure (probably accompanied by habits) of other, thus in Chalcididous insects, which I brought from Australia, probably live in fl ower & have Elytra formed from development of some other part of body. — there are hemipterous insects having spiny legs & running quick & general appearance of blattae — |
other Hemiptera strikingly resemble Coleoptera. —

Donacia. some orthopterous insects & some third [?] have got thighs with same peculiar structure & habits of clinging to rushes similar. — The question which I more immediately want are there Heteromera which have habits & part structure like Cuculionidae. — Are there any Crysomelidae with similar habits. But the Horae Entomologicae will tell this. —
What peculiar conditions the Staphylinidae on St. Pauls Rock must be placed under. |


Gould55 says most subgenera confined to continent, though we have seen species of subgenera scattered over it.
We have abundant instances of remarkable structures which as far as species is concerned superabundant. Showy [?] tail in cock peacock, widow bird. Birds of Paradise, Trogons. — the one feather in wing the curious feathers in tail of Edolius. Remarkable how small detail in structure prevail amongst the same species & subgenera in families. — thus the banded tarsi is common to all the Laniadae & Muscicapidae of new World, but not found in Old World. — |


If in any well developed family (Gould says)56 there is any marked colouring of plumage (as black & white bars on wings of Trogons or lengthened rump feathers) & one species has small band & others large, then he says from long experience you may be almost sure, that there exist intermediate species. — This is remarkable & would lead one to suppose that species in same group generally contemporary. This would lead one to expect that fossil forms would generally fill up genera & not species, which is not true with shells ??? It looks as if animals perished by error. [?] |


It is most wonderful how in every family of birds, even the most strongly marked, there is a preeminently aerial, formed for flight & great movement in the air, & likewise rasorial species & likewise perching (Gould),57 but the latter is obvious because all are so. —
Thus in Hawks there is a swallow, both in structure & habits (it cannot be doubted

53 unidentified.

that if swallow perished hawks & milvulus &c would instantly fill up their place.) — Humming bird there is strongly marked variety in the Tyrannidae. — Milvulus. —
Even flying woodpeckers, with powerful wings, but | tail stiff. — swallow & goat-sucker likewise exaggerated. — There is one most remarkable connection between these aerial representatives of the different families. — that sexes have same plumage. — this is applicable to swallow-hawk, (this not the case in swallow ??? which is most wonderful of all? whether in most aerial of swallow) Milvulus. & still more wonderfully to the Humming bird, which is one instance of its whole family where female is not dull. — I must observe that this pre-eminent structure is not always applicable to same habits, though swallow hawk milvulus may catch insects on the
wing & pratancola (? connected | with Chionis), yet the Tropic bird, has very different habits, though pre-eminently belonging to this type. ?Humming bird? the woodpecker Gould says he believes does but also on fruit. —
The Rasorial type is wonderfully shown in the long legged cuckoos with claw like lark (one in Australia is called swamp pheasant) goatsucker, parrots with claw like lark (N.B. The La jeune veuve parrot though so much on the ground has not this structure, instance of habit going before structure.) — | even one Kingfisher Gould has seen with long tarsi. — ground woodpecker Secretary bird. — & Mellisuga Kingii very rasorial for type. — Now here I must observe these characters vary in degree in last instance hardly at all developed, not confined to one species, but generally small genus ? are there not many ground parrots ? are there not many ground wood-peckers? —

In each division Gould thinks he can trace structure for insects & structure for vegetation. — |


In conservation in Museum I could not discover any other clear relations besides aerial, & terrestrial — How is it in water birds. —there are walking forms in water birds. — but no web forms in land birds. — Groups of very different value have their representatives, the rasorial may be observed even in Lessonia &c. &c. In relations of affinity all organs change together, in analogy certain parts perfect of typical structure certain parts changed |


Has S. Africa & Australia, & S. America very few forms in common, but each several with Europe & northern Asia, & Northern America. — may we not look at these Northern regions as the receptacles of the wanderers out of the rest of the world? — Will this not agree with Waterhouse58 & mammalia. — We have clear indication |
have elapsed. — let these families take domestic animals with them they might be supposed to change & make genera of birds analogous, animals would be possessed by the different races of man, yet altogether different. — To make this case perfect, we must suppose men instead of mere colour & trifling form & lead on to become greatly changed in structure & even to certain degree in habits, yet we may have there analogies. — We must try [?] races of such men living in same country but
separated, now | if one or the other race had become eminently aquatic, (N.B. aquatic i.e. relation to element & not minding particular trades.) — then the second

race would not obtain a cast of washing men, but might have the preexisting race, thus the analogy would not in all cases be produced. but would depend on exclusion. —

The same characters which are analogical in a genus with respect to rest of its family as in ground cuckoos, is affinity with respect to species of each other, because we suppose all descended from same. — but if two original species, each became ground, then the relation of all the ground cuckoos would not be affinity, but the truth would never be discovered. |


The quantity of life on planet at different periods depends on relations of desert, open ocean, &c. This probably on long average equal quantity, 2° on relation of heat & cold, therefore probably fewer now than formerly. The number of forms depends on the external relations (a fixed quantity) & on subdivision of stations & diversity, this perhaps on long average equal. |

My definition of species has nothing to do with hybridity, is simply, an instinctive impulse to keep separate. which no doubt be overcome, but until it is these animals are distinct species.

Waterhouse says of affinity of many insects may be told by their larvae) but the acts of condensing must alter method of generation. — Heaven knows how. — This reaction takes place in every organ. Hence method of generation is very good general character in those animals where much change has been added, as it speaks to amount of change only & not kind : insects, vertebrata — plants. at first classification on generation might appear convention |

Those who say philosophically to a certain extent, nothing but experience will tell us when group is true, — there are no genera if mammalia are adduced, say oh look to your fossils, now if extinction had gone, without creation this would have been fair, but to place all that ever have lived into one list is unfair (moreover what will become of the future creations, if the list is now perfect. —) the creator so creates animals, it will be said, that although at any one there are gaps yet altogether he has created a perfect chain *** supra on next page |

These abortive organs in some males animals, mammae in man, capable of giving milk.

The females of some moths, like glowworm have rudimentary wings so nature can produce in sex what she does in species of Apterix.

This is important because if these abortive wings in the female are allowed to the fully organized wings of the male rendered abortive in the womb — if these apparently useless organs do indicate such origin, then we are bound to consider abortive organs of same tendency in species. this is capital & novel argument. — (there is paper by Yarrell77 in Zoolog.

W. D. Fox1 has a cat which he bought in Portsmouth, said to come from coast of Guinea, — ears bare, skin black & wrinkled — fur short (tail cut off in progeny peculiar) limbs very long, eyes very large, very fierce to dogs. — otherwise habits not different; tone of voice perhaps rather different. Crossed with common cat, exact variety unknown, three kittens alike each other, partaking very closely of form of mother : more than of the common cat. — ([in pencil:] Ch IX Mongrels Hybrids) Fox has half Persian cat which bred with unknown common house cat. — had four
kittens. two appeared | so very like common cat, that they were killed & other two very closely resembled in form of tail, fur &c. to the half bred Persian. — Here then we have clear case of heterogenous offspring from one impregnation. ?is this one impregnation, or two impregnations one giving half character & other more of English, but the effect is the same. —


Fox thinks that when a wild animal is crossed with a | tame, offspring always takes most after wild. — i.e. that no domesticated ones have been so long as wild one under present form. — Fox has seen several cases of foxes and dogs crossed. offspring always more resembled foxes than dogs (mem Jackal in Zoolog. Gardens) He has seen in a show half wolf & half Esquimaux dog which appeared to be intermediate between two parents. — this is very interesting as Esquimaux dog approaches to species. Again he has seen several crosses between Esquimaux dog & common
dogs & Fox thinks they decidedly take | much more after Esquimaux. — this agrees perfectly with Yarrell2 & no leading question was put. —
Fox thinks half Lion & Tigers are exactly intermediate in character & kittens alike each other. —

Even in children of parents one sometimes resembles one parent & one another & are not exactly intermediate. — | &
another leader mare. — this stallion though eager to all other mares had been entirely broken from these mares, (though horsing every month) & worked in the same cart in loose chains, by being at first beaten from her, & always accustomed to her. — even parallel to brothers & sisters in mankind. —

The case of all blue eyed cats (Fox has seen repeated cases) being deaf curious case of corelation of imperfect structure. — |


Fox says in Lord Exeter's Park or in the Duke of Marlborough there is a breed of white-tailed squirrels, which form a marked wild variety, doubtful whether all are white. Fox says half Muscovy.

Fox says a settler near Swan river lost his two cows entirely, changed his residence a great many miles — yet one day a cow walked in, then disappeared, & three days afterwards came again, bringing with her the other & younger cow. — |


Mr. Blyth3 remarked that greater difference in the 4 Struthionidae, than in many large orders of birds. The Emu & Cassowary closest. — Ostrich & Rhea closest. —

(& 2 Rheas still closer). — Mr. Blyth asked whether structure of pelvis &c was not adaptive structure, like little wings of Auk which does not make that bird a Penguin. — (i.e. whether relation in one point or many) Owen4 answered that all characters might be considered as adaptative and that he did not see where the line could be drawn. — thus the most remarkable character in Apteryx, small respiratory system;
even much smaller | than in other Struthios was adaption to little movement. — nocturnal crawling bird. — Wings reduced to rudiment. — clavicle scapula &c. strongly developed to aid in breathing. —

Animals from Hobart Town mentioned, it seems most of species from there now found in Australia. —

New species of Moschus characterized by Ogilby.5 who observed that the young of this animal which is so anomalous among true deer yet is spotted like so many deer. — very curious like some facts of Mr. Blyth on birds. — |


Dr Bachman6 tells me line of Rocky Mountains separates almost all Mammals of N. America & many birds, which however are most closely represented. — Thus the red breasted thrush is separated by one not differing except by black line. — A Bunting by one only differing by some permanent white streaks. — &c. &c.

Dr Bachman has crossed cock Guinea Fowl with Pea Hen. — offspring female,
yet so infertile never even in seven years produced even an egg. — | a most curious bird, did not seem to know itself, at last associated with the ducks. — most strange voice often in the night, like peacock. — tail as long as Pea hen. — about intermediate. — (In Zoolog. Garden there is hybrid of Penguin duck a variety of Muscovy with goose!!)

Dr Bachman regularly breeds in Carolina for his table Muscovy & common ducks — they are produced in full equal numbers with pure bred (just like common mules)
& lay many eggs but never produce inter se or with | parent species. — The hybrids do not vary (i.e. the hens all alike & cocks all alike) more than parent species. — Mr. Blyth remarked only near species or varieties produce heterogenous offsprings. — are not the hybrid pheasant & grouse different — (if so Chinese pigs & common must be considered as distant species?? or is time the varying element). Then do those species which breed most freely & produce somewhat fertile offspring produce heterogenous offspring.

It appears certain that hybrid Muscovy & common duck have been shot wild (escaped from Carolina)? off New York, therefore instincts not imperfect. Are Pheasant & Grouse homogenous? |


I observe Bachman calls these Hybrids new species.

Yarrell says the bird fanciers say the throw of any two species crossed is uncertain.

Yarrell remarks he has somewhere met conjecture that all salt-water [recte fresh water] fish were once salt water (as they almost must have been on elevation of continents) but Ogilby well answers that nearly all F.W. Fish are Abdominals ∴ that order first converted. — is it an old order geologically? |

Macleay8 & Broderip9 when talking of some Crustacean, like Trilobite (Polirus??) female blind & quite different form from male with eyes! — (are not these differences in sex confined to annulosa?) remarked that young of Cirrhipedes can move & see, parents fixed, — young of sponges move. — young of Cochineal insects move about & see, parent female fixed & blind: — Macleay observed all these facts proves that perfection of organs have nothing to do with perfection of individual, though such relation seems common, but the perfection consists in being able to reproduce. |
Here there is some error — Observed, nature does nothing in vain, therefore organs fitted to animals place in creation. — thus senses, especially sight connected with locomotion. (Mem. Dr. Blackwell (Abercrombie)10 comparison of sight to threads.) — Hence the Pecten which moves imperfectly has eye-point, but Brodrip added it has been stated that stationary Spondylus has eye-points — Macleay then answered, because nature leaves vestiges of what she does — does not move per saltum — yet does nothing in vain!! |

(There are some ¾ birds of which I think there must be some mistake in their origin)


Saw cross between Penguin Duck from Bombay & Canada Goose. — Former strange mishaped bird & looks very artificial bred but Mr. Muller says that breeds
larger numbers, & rears an | unusual number out of any one nest, even more than common duck — Male Penguin was crossed with hen Canadian offspring, I should say in every respect most like Penguin duck. — which is strange anomaly in Yarrells Law.20 — it probably is explained by the vigour of their propagating powers. (as if they were a good species or local variety & not effect of breeding in & in, like our pidgeons).

The male of every animal certainly seems chiefly to impress the young most with its form & disposition |
Saw there young duck, like each other, — (& not very like either either … or Pintail ducks) from which they were descended they … from ½ pintail drake into pintail. — of them there were four two like each other & two dark coloured & different. — the former were the parents of the little ones |
Same man crossed Jackal & dog (offspring did not go to teat but parts swelled, though no fluid came from them. — showing how gradually every change is effected) — the one in the garden is from father dog & hence general appearance of face & tail somewhat like dog — though it has full share of Jackal shape |
of white speckles on elbow joint — in Bewick drawing21 the the rock Pidgeon has not: now how many wild pidgeon have spangles on this part: this will be well worth working out. —
Study Temmincks22 work on Pidgeons, & see whether feathered legs, — car[r]uncles on beak as in Muscovy duck, crested feather, pouters, fan tails, are found in any colours of plumage &c &c. Pouting pidgeon exaggeration of cooing. — & compare them with all the varieties. — Habits of rock pidgeon. — (I suspect Pennant23 has described them) — (Study horns of wild cattle. — & plumage of fowls — long ears of rabbits. — & long fur. — feathers on legs of Ptarmigan & in Bantam. —) In the Pidgeons trace the washing out of the forked band, like in plumage of ducks. — |

Goulds Willow Wren.) — (Goulds story of Water-Wagtails mistaken both species scattered over Europe) — The habits of some same North American & European birds slightly different — Barn Owl in the former place breeds in thick vegetation in swamps — owing to barn, perhaps not being left open to them. — In singing birds, part instinctive & part acquired — thus Yarrell has Lark & Nightingale which both sing their own songs though imperfectly. — Male birds always record their songs, it |

Black Cock. — the latter has crossed with the Ptarmigan subalpina in wild state. — Neilson24 has given figure of it. — In England no doubt the cross between Pheasant & Black game is owing to their rarity, as single female in wood with Pheasants would sure to be trod & in many parts of Scandinavia these birds are very far from common.— Under this predicament, probably, alone would species cross in wild state. — Is English red Grouse a cross between Black game & the subalpina of Sweden, (which in summer dress somewhat resembles Red Grouse) it may be so — but very improbably,
for it can hardly be | thought that the cross would have adapted it to changing circumstances. — More probably during known changes climate became unfit for subalpina, or some northern species, & being restricted species has been made. —

In the hybrid grouse between Black Cock & Ptarmigan (probably subalpina) former has blue breast, latter reddish, hybrid purple — be careful. See to hybrids between Pheasant & Black Cock & other hybrids.

28th We ought to be far from wondering of changes in numbers of species, from small changes in nature of locality.

I do not doubt every one till he thinks deeply has assumed that increase of animals exactly proportionate to the number that can live. — ..


Population is increase at geometrical ratio in FAR SHORTER time than 25 years — yet until the one sentence26 of Malthus no one clearly perceived the great check

26 This note, written on 28 September 1838, makes it possible to identify the sentence in T. R. Malthus's Essay on the Principle of Population which enabled Darwin to see how the pressure of natural selection is inevitably brought to bear. It was in the 6th edition, London 1826, vol. 1, p. 6 : "It may safely be pronounced, therefore, that the population, when unchecked, goes on doubling itself every twenty five years, or increases in a geometrical ratio ",

amongst men. — there is spring, like food used for other purposes as wheat for making brandy. — Even a few years plenty, makes population in man increase & an ordinary crop causes a dearth. take Europe on an average every species must have same number killed year with year by hawks, by cold &c. — even one species of hawk decreasing in number must affect instantaneously all the rest. — The final cause of all this wedging, must be to sort out proper structure, & adapt it to changes. — to do that for form, which Malthus shows is the final effect (by means however of volition) of this populousness on the energy of man. One may say there is a force like a hundred thousand wedges trying [to] force every kind of adapted structure into the gaps in the oeconomy of nature. or rather forming gaps by thrusting out weaker ones. — |

Those who have studied history of the world most closely & know the amount of change now in progress, will be the last to object to the theory on the score of small change — on the contrary islands separated with some animals &c. — If the change could be shown to be more rapid I should say then some link in our train of geological reasoning extremely faulty.

The difficulty of multiplying effects & to conceive the results with that clearness of conviction, absolutely necessary as the basal foundation stone of further inductive reasoning is immense.

It is curious that geology by giving proper ideas of these subjects should be absolutely necessary to arrive at right conclusion about species.


Changes of level &c. are easily recorded, but change of species not as — without every animal preserved, the latter pages in the history are perfect, | we obtain a glimpse only of the changes which the government is subject to. — further back we obtain here & there in order a scattered page, we find sensible change in the institutions & we suppose not only revolutions, but certain obliterations & first laws created, & yet with symmetry & regular laws that baffles idea of revolution. —

My very theory requires each form to have lasted for its time : but we ought in same bed if very thick to find some change in upper & lower layers.

Il se fonde dans cette conclusion sur la différence qui résulte de la comparaison des faunes des deux mers. Le plus grand nombre des Poissons de la Caspienne sont des Poissons d'eau douce. Cette mer est de la plus grande pauvreté en animaux marins, surtout quand on la compare à la mer Noire. Et cependant, dit M.

Decemb. 25th Lyell says the elevated shells in Bayfields district are much more like those of Scandinavia than of the N.

escaped into a hole, where | the old Eagle could not find it. — The parent bird another day brought to her young ones the cub of a fox which after it had fought well & desperately bitten the young ones would in all probability have escaped" — if it had not been shot by a shepherd who was watching the scene. — In Shiart Isld it is said, that an Eagle always procured its prey from another island. —

p. 175. 28 short eared owls were counted in a field where there was great swarm of mice. — |


May 29th . — Henslow says that he has not the slightest doubt that Festuca vivapara is the same species with F. ovina & was rendered vivaparous by growing in height. — yet he has seen it propagated in a garden, which is case precisely analogous to the Canada onion mentioned in Hort. Transact. Aisa caespitosa become vivaparous on mountain & yet can be raised in gardens. — Poa alpina, though generally vivaparous sometimes seeds. There are endless curious facts about every part of plant producing buds, so that Turpin52 says each cell of plant is individual. — Most plants which propagate rapidly by buds, layers &c. &c. do not seed freely. — The periwinkle seldom produces seeds, because it is thought to require insects to impregnate it. — it is allied to Asclepia, where this is always the case according to Brown. — |


Voyage of Adventure & Beagle.53 Vol. I. p. 306 Shells as well as plants of Juan Fernandez differ from American coast. Vol. II p. 251 about the drifting of animals on ice — p. 643 — very curious table of all the castes from Stephenson at Lima.


The same numerical relation (both in species and subgenera) between the Crag & Touraine beds, the one with neighbouring & Arctic sea, & the other with neighbouring & Senegal in sea — is remarkable. — Again the resemblance between the Superga
& Paris, numerically | the same with recent & yet almost wholly different, is same, as if Isthmus of Panama. — Those two cases highly improbable — yet I can see no other way of accounting for them. — Think over this — The Superga beds have many shells in common with Touraine & are not far distant, which as L. says is strong argument for their contemporariness. — How is this with the Eocene beds. — see Lyells54 tables —

Bennetts Wanderings55 Vol. II p. 155. By inference I imagine that there are Baboons in St. Thomas on W. coast of Africa. |

June 18th . Eyton57 tells me that Yarrell58 knows of a Gull which has laid in domestication eggs of two shapes & colour — Eyton has observed same thing in
Brent Goose | Eyton says some of the pidgeons in common Dovecot are very like a Himalaya species — leuconotes.

Magazine of Nat. History 1839 p. 106. Waterhouse59 refers to fossil remains of the Hamster. — is not this Siberian animal? —

Eyton60 says that the young of two hatches all alike between the male Chinese & female common goose took after the common goose thus contradicting (probably) Yarrells61 law & Walkers62 of the male giving form — they interbred & the young kept constant & all alike |


Waterhouse says some of the Galapagos Heteromera …[?] must come very near to Patagonian species. —

p. 18 of Temmincks63 Preliminary discourse to Fauna of Japan. — that the animals of islands N. of Timor are allied to the type of genera in isles de Sonda as well by those which are identical, as those which are different — now this is same as Galapagos facts &c. &c. — & it shows the cause which gives same species to different isld. is the same as that which gives genera. — now in case of large |
