We can however congratulate ourselves on the undoubted fact that the correspondence of Henry 2544 Oldenburg to Hevelius, 25 September 1674 435 Oldenburg does indeed, as we expected, illuminate the scientific 2550 Leibniz to Oldenburg, 6 October 1674 435 scene of the period (1662 — 77) when he was Secretary of the Royal 2604 Crawford to Oldenburg, 5 February 1674/5 435 Society, as no other material could do; that it has revealed a little 2658b Huygens to Justel, 18 April 1675 435 about Oldenburg the man is also gratifying, especially as what we 2690 Lister to Oldenburg, 27 June 1675 435 have learned shows much about the social structure of the English 2712 Oldenburg to Hevelius, 28 July 1675 435 world. 2726 Justel to Oldenburg, 18 August 1675 436 Here, as in previous volumes, we have aimed at completeness, 2730 Justel to Oldenburg, 28 August 1675 436 with exceptions for those letters whose texts were adequately 2735 Oldenburg to Lister, 4 September 1675 436 available at the time of going to press, namely letters to and from 2754 Oldenburg to Leibniz, 30 September 1675 436 Newton and Leeuwenhoek. For the first time we omit the Latin text of letters to and from Leibniz for July to October 1676, since these were printed with elaborate editorial textual criticism by the late Index 437 Professor J. E. Hofmann in Leibniz’s Samtliche Schriften (1976); but since no translation is provided there we have given a full English text. As before, we have provided only English text for Malpighi’s correspondence which has been printed in full in Latin by Adelmann, although he provides only summaries, not complete translations. We have not printed here papers by Boyle published in Phil. Trans., since these are not real letters, nor, as before, any undated suppositious letters later published in Boyle’s own works. In this volume we have annexed all those letters of whose existence for one reason or another we were unaware at the time the appropriate volume was completed, and we have also noted additional information and corrections to all previous volumes. XIV XV Our first expression of gratitude must be to the Royal Society Above all, we thank our patient secretaries, especially Fiona which, after encouraging and assisting the compiling of this Cooper who uncomplainingly coped with the tedious task of typing Correspondence over the years, has very generously loaned a sum of most of the manuscript, and Julie Hounslow who helped us money to make the publication of the last two volumes possible. complete it. As we have been for many years past, we are immensely grateful to the many libraries and institutions who have permitted us to Imperial College A. Rupert Hall reproduce manuscripts in their possession and have assisted us in February ig8o Marie Boas Hall obtaining texts: first and foremost the Council and ever-helpful librarians of the Royal Society; the British Library, the Bodleian Tackley, Oxford Library and its staff, the Cambridge University Library, the Public March ig82 Record Office, the Bibliothèque Nationale, the Observatoire de Paris, the Rijksuniversiteit in Leiden, the Hollandsche Maatschapij, the Bologna University Library, the Leibniz-Archiv of the Niedersàchsische Landesbibliothek and its staff, and the Staats- und Universitâts-bibliothek of Gottingen. Our debt to colleagues, friends and ever-helpful experts has naturally grown with the years. We can only continue to wonder at their patience. Dr D. T. Whiteside has never failed to assist us from his unrivalled knowledge of seventeenth century mathematics. Dr Heinz-Jürgen Hess of the Leibniz-Archiv assisted us with photostats and a Leibniz chronology. For patiently answering many questions we thank, among others, Mrs Magda Whitrow, Dr R. E. Loewe, Dr Eric Forbes, John Thackray, Judith Field, Michael Hunter, and Professor T. R. E. Southwood. We thank D. M. Schullian and G. E. Scala for their index to Birch’s History of the Royal Society, which has much facilitated editing. For the additions and corrections to previous volumes we thank various reviewers (whose suggestions we have often gladly adopted, although we have naturally reserved the right to accept or reject suggested emendations in the light of our own judgement) and, among many others, the following who either found us new letters or profoundly altered our understanding of existing ones: Dr Donald G. Bates, Jonathan Barry, Professor Harcourt Brown, Dr Pierre Chabbert, Dr R. Frank, the late Dr J. E. Hofmann, M. A. Hoskin, M. Hunter, R. McKeon, W. E. K. Middleton, T. K. Rabb, Mayling Stubbs, A. Turner, and D. T. Whiteside. For assistance in research we thank Dr Mari Williams, Anne Sant and Dr E. J. Browne. XVI xvu ‘i Abbreviated Titles Adelmann Howard B.
