The end of an era.

These volumes conclude a series initiated in 1974, marking almost fifty years of effort by a huge cohort of scholars. This review is thus a valedictory for the whole series as well as an account of what we have learned from the most recent volumes about Darwin's final years (1879-82). The project was begun by Frederick Burckhardt, who shared the editorial role for the early volumes with Sydney Smith and a rolling sequence of assistant editors and advisers who eventually comprised a significant fraction of the leading members of what used to be called the 'Darwin industry'. Smith passed away in 1988 (volume 7 notes his legacy). Burkardt too left this world in 2007 - volume 16, part 1 includes an obituary, but his name has been retained and Cambridge University Press still ask that the series be cited as 'Burkhardt et al.' Duncan Porter took over for volumes 8-15, again with a sequence of fellow editors and assistants, after which James Secord became head of the project through its final years. The dedications of successive volumes record the efforts of individual scholars who have aided the teams and the involvement of the many institutions and foundations that have leant moral and material support over the years. For those of us with Cambridge connections, the University Library will not seem the same without the presence of the team it supported.

Discovering Science from an Armchair: Popular Science in British Magazines of the Interwar Years.

Analysing the contents of magazines published with the stated intention of conveying information about science and technology to the public provides a mechanism for evaluation what counted as 'popular science'. This article presents numerical surveys of the contents of three magazines published in inter-war Britain (Discovery, Conquest and Armchair Science) and offers an evaluation of the results. The problem of defining relevant topic-categories is addressed, both direct and indirect strategies being employed to ensure that the topics correspond to what the editors and publishers took to be the principal areas of science and technology of interest to their readers. Analysis of the results of the surveys reveals different editorial policies depending on the backgrounds of the publishers and their anticipated readerships. The strong focus of the two most populist magazines on applied science and 'hobbyist' topics such as natural history, radio and motoring is noted and contrasted with the very limited coverage of theoretical science. In conclusion, a survey of changes in the contents over the periods of publication is used to identify trends in the coverage of science during this period.

Revisiting the eclipse of Darwinism.

The article sums up a number of points made by the author concerning the response to Darwinism in the late nineteenth and early twentieth centuries, and repeats the claim that a proper understanding of the theory's impact must take account of the extent to which what are now regarded as the key aspects of Darwin's thinking were evaded by his immediate followers. Potential challenges to this position are described and responded to.

Darwin's Originality.

Charles Darwin's theory of natural selection has been hailed as one of the most innovative contributions to modern science. When first proposed in 1859, however, it was widely rejected by his contemporaries, even by those who accepted the general idea of evolution. This article identifies those aspects of Darwin's work that led him to develop this revolutionary theory, including his studies of biogeography and animal breeding, and his recognition of the role played by the struggle for existence.
