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.

Collection comprising three manuscript notebooks of theoretical problems relating to mechanics compiled by James Clerk Maxwell mainly during his employment at King's College London, including exam questions on aspects of mechanics and geometry, 1860-1865; problems on the collision of elastic spheres and the dynamic relation between other solid bodies; the refraction of light; the relationship between heat and volume in materials; attraction between particles, 1860-1873; notes on the works of leading authorities on mathematics and physics including Arthur Cayley, Franz Neumann and Siméon Poisson, 1867-1873; bibliography of textbooks mainly on mechanics, [1860-1865]; list of scientific instrument suppliers, [1860-1865]; outline of the contents of Maxwell's Treatise on electricity and magnetism (1873).

Correspondence, diaries and other papers of Sir Alfred Charles Glyn Egerton, including some personal papers but largely relating to The Royal Society and particularly to wartime activities and post-war research needs in Britain. The diaries form an almost complete record of Egerton's career during the period 1943-1959. Earlier diaries date back to 1917 and the period 1929-1930, but for the most part they relate to the period 1938-1941.

The papers of John Edmund Bowen consist of two manuscript notebooks containing notes on lectures delivered by Professor Joseph John Thomson, Cavendish Professor of Physics at Cambridge, 1911-1912. Bowen's notes consist of detailed summaries of Thomson's lectures on subjects including the discharge of electricity through gases, recombination of ions, recent developments in researches on light and electricity, scattering of electromagnetic radiation and the quantum theory of light.

Anonymous student's notes on chemistry lectures by Joseph Black (1728-1799) when Professor of Medicine and Chemistry, University of Edinburgh, on subjects including chemicals and heat.
