Henry Oldenburg, born in 1619 in Bremen, Germany, first came to England as a diplomat on a mission to see Oliver Cromwell. He stayed on in England and in 1662 became the Secretary of the Royal Society, and its best known member to the entire learned world of his time. Through his extensive correspondence, now published, he disseminated the Society's ideals and methods at home and abroad. He fostered and encouraged the talents of many scientists later to be far more famous than he, including Newton, Flamsteed, Malpighi, and Leeuwenhoek with whom, as with many others, he developed real friendship. He founded and edited the Philosophical Transactions, the world's oldest scientific journal. His career sheds new light on the intellectual world of his time, especially its scientific aspects, and on the development of the Royal Society; his private life expands our knowledge of social mobility, the urban society, and the religious views of his time.

Vol. 2: This is the second in a six volume compendium on the correspondences of John Wallis (1616-1703). Wallis was Savilian Professor of Geometry at Oxford from 1649 until his death, and was a founding member of the Royal Society and a central figure in the scientific and intellectual history of England.

The Correspondence of John Wallis (1616 -1703) is a critically acclaimed resource in the history of early modern science. Volume IV covers the period from 1672 to April 1675 and contains over eighty previously unpublished letters. It documents Wallis's role in the crucial debate over the method of tangents involving figures such as Sluse, James Gregory, Hudde, Barrow, Newton, and Christiaan Huygens. In this way it illuminates further an important part of the history of the calculus. Wallis's letters also provide valuable new insights into mathematical book production and the importance of the international exchange of books in the growth and dissemination of mathematical knowledge. We learn more about the part played by the intelligencer John Collins and the astronomer royal John Flamsteed in the edition of Jeremiah Horrox's Opera posthuma, published by Wallis in 1673. There are also new insights on the background to Wallis's early work on equations, and the reasons why he criticized Gaston Pardies's proposed tract on motion. The causes of the breakdown in Wallis's epistolary relation to Christiaan Huygens following the publication of the Horologium oscillatorium in 1673 are also revealed. Many letters reflect Wallis's active involvement in the Royal Society. Through the medium of correspondence the Savilian professor participated in numerous debates such as those over the anomalous suspension of mercury in the Torricellian tube or Hevelius's use of plain sights in positional astronomy. The volume allows us to gain a deeper understanding of the background to these debates. Furthermore, the volume throws important new light on the history of the University of Oxford and of the University Press in the early modern period. As keeper of the University Archives, Wallis was one of the institution's highest officers. Scarcely any event of note concerning the University did not require his involvement in some way, and this is reflected in numerous letters and documents which the volume publishes for the first time.

A General History of Horology describes instruments used for the finding and measurement of time from Antiquity to the 21st century. In geographical scope it ranges from East Asia to the Americas. The instruments described are set in their technical and social contexts, and there is also discussion of the literature, the historiography and the collecting of the subject. The book features the use of case studies to represent larger topics that cannot be completely covered in a single book. The international body of authors have endeavoured to offer a fully world-wide survey accessible to students, historians, collectors, and the general reader, based on a firm understanding of the technical basis of the subject. At the same time as the work offers a synthesis of current knowledge of the subject, it also incorporates the results of some fundamamental, new and original research.

This is the first modern biography to place Henry More’s (1614-1687) religious and philosophical preoccupations centre-stage, and to provide a coherent interpretation of his work from a consideration of his own writings, their contexts and aims. It is also the first study of More to exploit the full range of his prolific writings and a number of unknown manuscripts relating to his life. It contains an annotated handlist of his extant correspondence.

Winner of the 2017 John Thackray Medal awarded by the Society for the History of Natural History, U.K. Martin Lister (1639–1712) was a consummate virtuoso, the first arachnologist and conchologist, and a Royal physician. As one of the most prominent corresponding fellows of the Royal Society, many of Lister’s discoveries in natural history, archaeology, medicine, and chemistry were printed in the Philosophical Transactions. Lister corresponded extensively with explorers and other virtuosi such as John Ray, who provided him with specimens, observations, and locality records from Jamaica, America, Barbados, France, Italy, the Netherlands, and his native England. This volume of ca. 400 letters (one of three), consists of Lister’s correspondence dated from 1662 to 1677, including his time as a Cambridge Fellow, his medical training in Montpellier, and his years as a practicing physician in York.
