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.

This paper is Vol. 2, No. 6 of the Historical series.

OF the pages excised by Darwin from his Notebooks on Transmutation of Species, 28 have been recovered. In the British Museum (Natural History) 10 pages were found among the Darwin papers and letters deposited by Mr. Robin Darwin; these are indicated by an asterisk* following the Roman number in the margin indicating the number of the Notebook concerned. The remaining 18 were found among the Darwin MSS. in the Cambridge University Library by Miss M. Skramovsky with the kind assistance of Mr. P. Gautrey; these are indicated by a dagger†. The particular Notebook from which the pages were excised was determined by comparison of the scissor-cuts with those of the stumps in the Notebooks.

The reasons which led Darwin to adopt the method of cutting pages out of his Notebooks are obscure. His entries of "All useful pages cut out", made in December 1856, show that he wanted to use them for his large work on Species on which he was then engaged. Two of the pages printed below were found attached to the manuscript of his larger work. Attention to this fact was first kindly drawn by Professor Robert C. Stauffer of the University of Wisconsin. What the fate of the many other comparable pages can have been, it is, unfortunately, not hard to conjecture. It may not be legitimate to draw conclusions from the relatively small number of excised pages that have been found, but it is difficult to avoid asking the question why these particular pages should have been considered by Darwin to be more "useful" than many of those which he did not excise.

One of the pages, (105 from Notebook II) contains material about the similarity of nest-building instincts in different species of thrushes in the Old and New Worlds, which can be traced right through to the Origin of Species (World Classics edition, 1956, page 304). Another page (160 from Notebook II) on woodcocks in Madeira having lost their migratory instinct, appears in the Essay of 1844 (Cambridge University Press edition, 1958, p. 142).

These pages are printed below in order to make the transcription of Darwin's Notebooks on Transmutation of Species as complete as the available material allows. We should like to express our thanks to Miss M. Skramovsky for her invaluable help in this work.

The page references are to the Manuscript pages of the Notebooks.

Although in plants you cannot say that instincts perverted yet organization especially connected with generation certainly is. —

The dislike of two species to each other is evidently an instinct; & this prevents breeding. now domestication depends on perversion of instincts (in plants domestication or perversion of structure especially reproductive organs) & therefore the one distinction of species would fail.

Bachman2 tells me in Audubon3 there is most curious history of first appearance of the S. American Pipra Flycatcher which is now becoming common — likewise of the Hirundo fulva4 (added by Audubon in appendix) showing what changes are taking place & how birds are extending their ranges — even migratory birds like swallows.

Of migrations of birds he mentioned many most curious cases. The birds seem to follow narrow bands, certain kinds as gallinules taking the low country near coast &
other the mountains, & then5 | appearing to remain about a fortnight. See Silliman's Journal 1837. Paper by Bachman.6 that is succession of birds. — in some species as Tanagra males come first & then females in flocks as in English nightingales — other birds (& this seems common kind migration of America) migrate singly flying few miles every day & generally by night — other birds which is strictly diurnal, migrates singly by night. — others in flocks. These birds seem clearly directed by kind of country; kind of migration quite different in species of same genus.

Reference has already been made to the great difficulty experienced in transcribing the text of Darwin's Notebooks owing to indistinct formation of letters, abbreviations and slurred endings to words, telegraphic style without grammatical construction, and intercalation of phrases between lines. It was for this reason that no attempt was made to produce anything approaching a facsimile edition, but to give a text with the minimum of complication. Unfortunately, but as expected and stated, this has not been devoid of errors in transcription. Some of these are inadvertent omission of a word; others are faulty or doubtful readings. They have emerged as a result of re-exarnination of the text, comparison of the text of the First Notebook with that published3 by Professor Paul H. Barrett of Michigan State University, and a series of corrections kindly supplied by Dr Sydney Smith. The majority of these has been accepted, and a list of corrigenda drawn up, which is printed below in order to make the printed text of Darwin's Notebooks as accurate as possible.

In most cases the identification of a work as the one to which Darwin referred can only be conjectural where he did not give the precise reference himself. Additional references are therefore printed below to supplement those already given. Some of these references are derived from the edition of Darwin's First Notebook published by Professor Paul H. Barrett1 ; others are due to the kindness of Dr. Sydney Smith.

Page references are to the printed pages of previous Numbers of this Volume of the Bulletin.

First Notebook on Transmutation of Species (C.U.L. Darwin MSS. 121)

Some of the page references to Lamarck's Philosophie Zoologique, Paris 1809, refer to the 1873 edition. The correct references to both editions are as follows:—


footnote 6 read tome 1, p. 55 (1873 ed. p. 73).
7 read tome 1, p. 59 (1873 ed. p. 76).
8 read tome 1, p. 99 (1873 ed. p. 112).
9 read tome 1, p. 77 (1873 ed. p. 93).

[page] 199


footnote 6 read tome 1, p. 266 (1873 ed. p. 263).
7 tome 1, p. 65, tome 2 p. 84 (1873 ed. tome 1 p. 82, tome 2 p. 78).


footnote 1 read tome 2, p. 279 (1873 ed. p. 256).
2 tome 2, p. 283 (1873 ed. p. 259).
3 tome 2, p. 286 (1873 ed. p. 262).


footnote 1 read tome 1, p. 57 (1873 ed. p. 75).
2 Dr. Sydney Smith has identified the reference: J. E. Gray, "Remarks on the difficulty of distinguishing certain Genera of Testaceous Mollusca by their Shells alone, and on the Anomalies in regard to Habitation observed in certain Species ", Phil. Trans. Roy. Soc., vol. 125, 1835, p. 301.


footnote 1 cf Barrett op. cit., p. 285, note 7.


footnote 2 cf. Barrett op. cit., p. 285, note 2.


footnote 1. The references to Mr. Don probably refer to David Don rather than George Don. David Don was Librarian to the Linnean Society and author of numerous papers on the distribution and relations of plants. According to Dr. Sydney Smith, Darwin did much of his reading in the libraries of Learned Societies, and as Darwin's reference on the excised page 187 of the first Notebook, printed above, has definitely been identified with David Don, the other references to "Mr. Don" probably relate to him.


footnote 4 cf. Barrett op. cit., p. 288, note 50.


footnote 4. The anonymous author of the paper in the Edinb. New Phil. Journ. has been identified by Dr. Sydney Smith as Robert Jameson (1774-1854); also cf. Barrett op. cit., p. 289, note 66.


footnote 3 read tome 1, p. 143 (1873 ed. p. 153).


footnote 2 cf. Barrett op. cit., p. 288, note 50.
4 for N. Baer read Karl Ernst von Baer.
5. The reference is not to William Darwin Fox, but to Sir Francis Sacheverel Darwin (1786-1859), son of Erasmus Darwin (1731-1802) by his second wife Elizabeth Chandos-Pole. Francis Sacheverel Darwin was therefore half-brother to Dr. Robert Waring Darwin (1766-1848, Charles Darwin's father) and uncle of Francis Galton. He travelled

widely and lived at Sydrope, Derbyshire, where he kept wild animals, including wild boars. (Karl Pearson: The Life Letters and Labours of Francis Galton, Cambridge 1914, vol. 1 pp. 22 & seq.) Information kindly supplied by Lady Barlow.


footnote 2, 5, perhaps M. B. Wynn of the Preface to The Breeders' and Fancier's Pedigree Book. cf. p. 190 footnote 2 supra.


footnote 4 for P. 26 read xxvi

7. See correction to footnote 1, p. 50.


footnote 3 read tome 2 p. 279 (1873 ed. p. 256)


footnote 5 cf. Barrett op. cit., p. 294, note 133.
