Scientific and other papers sent to the Royal Society, presented at meetings of Fellows, or commissioned by the Society. They form a complementary series to the Early Letters, both of which were superseded by the Letters and Papers. Many of these items, referred to as the 'Guard Books', are duplicated in the Register Book of the Society. The classification is a simplified form of the 'Philosophical Transactions' abridgment by John Lowthorp. This arrangement was completed in 1741 by Thomas Birch. The majority of the papers in these volumes are manuscript, but a few printed documents occur throughout the series. Some of the papers are earlier in date than the grant on 15 July 1662 of the First Charter to the Society. The Committee of Trades seems to have been associated with the earlier meetings of those philosophers who subsequently became Fellows, and produced a number of practical papers, some of which were written in 1639 and which are mostly found in Volume 3(i). There are still earlier documents, mostly in Volume 25, which may have been included in the gift, in 1667, of the Arundel Library.

Laboratory notebooks and records of C T R Wilson.

Working papers and correspondence of Sir Francis (Franz) Eugene Simon. Scientific notebooks in the collection date from 1919-1934, largely the period of Simon's researches on low temperature physics at the Physikalisch-Chemisches Institut of Berlin University, and subsequently at Breslau. Other notes and manuscripts for lectures and articles are post 1930, while a large group of correspondence files are from the years 1922-1956, providing a full account of Simon's dealings with many fellow scientists and scientific organisations. Individual letter files concern V.M. Goldsmidt, Max Born, Gwyn Owain Jones and Nevill Mott among many other notable figures. Details of Simon's involvement in atomic energy development are to be found in papers on uranium isotope separation (MAUD Committee notes) and UK Atomic Energy Authority correspondence. Simon's professional appointments as head of the Clarendon Laboratory and as science correspondent to the Financial Times are represented by substantial groups of letters. There are twelve notebooks with some associated papers; the series also includes files of lectures, articles, cuttings and souvenirs, including photographs, with files of correspondence. Two later additions to the collection consist of correspondence and files highlighting Simon's contacts with industrial firms, universities and international organisations.
