1 For the first of these, see Vorzimmer, P. J., ‘An early Darwin manuscript: the “Outline and draft of 1839”’, Journal of the history of biology viii (1975), 191–217Google Scholar. Vorzimmer discusses in detail the dating of the outline and of the draft, admitting that while some evidence favours 1839, the two documents may be of different dates and both later than 1839. The thirteen-page draft deals only with domestic variation. The outline, published earlier by Francis Darwin in his introduction to the Sketch and Origin, identifies the three parts of a projected work on the origin of species by natural selection, as I have explained later in this review. Apart from Stauffer's edition of Natural selection, I refer here to the edition of the Sketch and of the Essay in Darwin, C. and Wallace, A. R., Evolution by natural selection (Cambridge, 1958. Reprinted, New York and London, 1971)Google Scholar which includes Francis Darwin's 1909 introduction to those writings, and to the facsimile of the first (1859) edition of the Origin of species (Cambridge, Mass., 1964).Google Scholar
