Work on the present volume has been supported by grants from the British Academy and the Isaac Newton Trust, and its publication has been assisted by a grant from the Scouloudi Foundation in association with the Institute of Historical Research. I am very grateful for this support, and to Professor Nick lardine of the Department of History and Philosophy of Science, Cambridge, and the Departmental Administrator Tamara Hug, for administering the money. The project has continued to be housed by Cambridge Uni versity Library, despite increasing limitations on office space there; the Library management’s forbearance has enabled this volume to be completed without too much disruption. I also thank the Master and Fellows of Jesus College, Cambridge, both for their contribution towards the pro ject’s running expenses and for their generous tolerance as employers. On the intellectual side, I am indebted to many colleagues at Cambridge University Library for their advice and help: to the staff of the Department of Manuscripts in general and especially to Adam Perkins, RGO Archivist, for facilitating access to documents and discussing queries; to Valerie Hall for French translation, John Hall for Greek, and Elisabeth Leedham-Green for un ravelling palaeographical puzzles; and to the staff of the Darwin letters project for friendly en couragement. The project has benefited over many years from the assistance of staff at other institutions holding Flamsteed material (as listed in the next paragraph), especially those of the Royal Society’s Library. I am also grateful to Irene Hughes for her accurate wordprocessing of texts for the present volume, to Margaret Farrar for helping with the checking of transcriptions and with some of the final editorial tasks, and above all to Rosemary Yallop for voluntarily checking and proof-reading a formidable pile of printout. Janet Dudley has compiled the index, and is preparing a cumulative index of all three volumes (incorporating a reindexing of volume one), which will be available in electronic form through IOP’s website (at flamsteed.iop.org). Finally, on behalf of everyone who has devoted time and effort to the project, I would like to thank Jim Revill and his staff at IOP for their continuing commitment to its completion. We are grateful for permission to reproduce documents in the possession of (in order of their appearance): the Particle Physics and Astronomy Research Council (in respect of the Royal Greenwich Observatory Archives, at Cambridge University Library); the President and Council of the Royal Society; the Bodleian Library, University of Oxford; Saltykov-Skchedrin State Public Library, St Petersburg; the National Library of Wales, Aberystwyth; a private owner; the Royal Astronomical Society; the Syndics of Cambridge University Library; the Master and Fel lows of St John’s College, Cambridge; the Public Record Office; the Öffentliche Bibliothek der Universität Basel; the Master and Fellows of Trinity College, Cambridge; the British Astronomi cal Association; Columbia University Libraries, New York; the National Library of Scotland, Edinburgh; and the Biblioteca Universaria, Pisa. Finally, on a more personal note, I should like to thank Mr Derek Finnis of Salisbury District Hospital, and Mr Robin Crawford and Dr Helena Earl, both of Addenbrookes Hospital, Cam bridge, with their colleagues and staff, whose timely and skilful interventions have ensured my survival to complete this final volume. I owe an even greater than usual debt of gratitude to my family and friends for their support during this alarming episode.
