The vast majority of the material relates to Dent's research and clinical interests and falls into four main categories: correspondence files; files created around the publication of papers; lecture notes and symposium papers; and case/research notes. There are also smaller quantities dealing with other aspects of his career, such as the administration of UCH Metabolic Ward. The papers thus reflect most of Dent's scientific and clinical interests. This research is mainly represented by the abstracted documentation which he kept with drafts of his published papers (see section E.1) and also by correspondence about cases and clinical case notes (see section C.5). To a lesser degree they also illustrate the work at the laboratory bench which underpinned much of this research. For example, a file of unidentified paper chromatograms has been preserved (C.2/10) to illustrate one of Dent's methods of working, as described by his colleague, Heathcote, and quoted in the Biographical Memoirs of Fellows of the Royal Society, 1978: 'Paper chromatograms were not to be thrown away. They were filed and, since the colours faded, the outline of each spot was drawn in and the intensity of the colour was indicated by a number.' The way in which Dent compiled a large series of files around drafts of scientific papers also illustrates the importance of the published paper to him as a stage in the research process. An incomplete collection of reprints of Dent's published papers may be found in section E.2 of the collection.

The collection provides good documentation of many aspects of McIlwain's career and his contribution to the development of neurochemistry in the UK and internationally.

Section A, Biographical, brings together obituaries, curricula vitae and bibliographies, and material relating to the various stages of McIlwain's scientific career, especially in the 1930s and 1940s, his appointment to the Biochemistry Chair at the Institute of Psychiatry in 1954 and the symposium held in his honour on his retirement in 1980. The section also presents a significant body of material relating to McIlwain's undergraduate studies at King's College, University of Durham, including essays and notebooks.

Section B, Institute of Psychiatry, is principally papers relating to the activities of McIlwain's own Department of Biochemistry and especially its teaching programme in neurochemistry. There is also material relating to various government and University of London enquiries into medical education.

Section C, Research, includes copies of McIlwain's M.Sc. and Ph.D. theses, notes, drafts and reports for early work in the 1930s and correspondence 'from the Lab' for the 1930s and 1940s.

Section D, Publications, lectures and broadcast, is the largest in the collection. It presents significant documentation, especially correspondence, relating to his textbook Biochemistry and the central nervous system which went through five editions, 1955-1985, and important editorial correspondence for the Biochemical Journal (member of the Editorial Board, 1946-1950), Biochemical Pharmacology and Journal of Neurochemistry. There are also drafts for lectures and seminars for scientific audiences in the UK and abroad, principally from the 1960s onwards.

Section E, Societies and organisations, documents McIlwain's involvement with a number of UK and international bodies including the Biochemical Society, the International Brain Research Organisation and the International Society for Neurochemistry (ISN) of which he was a founder member and from 1984 'Historian' of the Society with responsibility for its archives.

Section F, Visits and conferences, covers the period 1947-1993 and is of particular interest for its documentation of the historical sessions which McIlwain organised at ISN meetings.

Section G, Correspondence, presents an alphabetical sequence of McIlwain's correspondence including significant exchanges with a number of distinguished mentors and contemporaries such as G.R. Clemo, F. Dickens, K.A.C. Elliott, P.G. Fildes, S.S. Kety, H.A. Krebs, Derek Richter and F.L. Rose, and a chronological sequence of shorter scientific correspondence covering the period 1938-1992.

There is also an index of correspondents.

Papers covering Hey's career, 1930-1971, including scientific papers, lectures, notes relating to departmental administration, and papers by others. File of correspondence, 1936-1937, chiefly with Professor William Alexander Waters, Professor of Chemistry at the University of Durham, relating to Waters' investigations into reactions involving free radicals and the subsequent publication of a paper on the same in Chemical Review, and including a draft and final version of Waters' paper on 'Decomposition reactions of the Aromatic Diazo Compounds', read to the Royal Society of Chemistry in Dec 1936.

Papers of Professor John Stodart Kennedy, 1915-1993, comprising biographical and autobiographical papers, 1915-1992, including Kennedy's autobiographical notes, family and personal papers, diaries;
papers relating to research, 1939-1992, documenting most stages of his scientific career from the 1930s, including wartime service; his periods at Cambridge, Imperial College and Oxford, categorised alphabetically by topic including aphids, behaviour/behaviourism, ethology, locusts, mosquitoes and motivation; photographs and observations in Albania, 1939; drafts and exchanges of ideas for his book of 1992;
papers and correspondence relating to Imperial College, 1963-1987; papers relating to lectures, papers and broadcasts, 1935-1987; publications, 1939-1992; societies and organisations, 1937-1991, including the Anti-Locust Research Centre; scientific and general correspondence, 1937-1992, with friends and colleagues such as Donald Livingston Gunn, Vincent Brian Wigglesworth, many overseas correspondents including scientific exchanges; papers relating to references and recommendations, 1954-1991, including correspondence with editors, authors and publishing houses; photographs, 1942-1985, notably of the work of the Middle East Anti-Locust Unit, 1942-1944, wind-tunnels, group photographs of meetings and symposia.

Papers of Adam Sedgwick, 1816 and 1843-1854, comprising:

Two notebooks from Sedgwick's tour through the continent of Europe, June-September 1816; manuscripts of Sedgwick's papers, mostly on the geology of Wales, which were read and later published by the Society, 1843-1854.

Scientific papers sent to the Royal Society which remained unpublished at their time of receipt, or which were abstracted in the Society's 'Proceedings' after being read at a meeting of Fellows. Early papers in this sequence are occasionally of interest in being preserved complete with associated correespondence (pre-dating Referees Reports); for example, the Charles Wildbore - Nevil Maskelyne letters 1787-1790 (AP.7.16-34). Mid nineteenth century papers of some significance may exist, in both original and abstracted form, such as HWF Talbot's 'Some account of the art of photogenic drawing' (AP.23.19) The Society's policy now is to return rejected scientific papers to authors, so any current additions to this collection usually take the form of unpublished supplementary data to published papers.

Although Barlow is best known for his original researches on infantile scurvy, there is very little material relating to that subject in the collection. There are manuscript drafts of his address to the Royal Medical Society of Edinburgh and his Bradshaw Lecture on infantile scurvy (BAR/E1-2), but the bulk of the clinical and scientific component of the papers relates to other matters, particularly Raynaud's disease and erythromelalgia, diseases to which Barlow turned his attention later in his career.

Among Barlow's clinical papers is a notebook recording minutes of a 'Clinical Club', 1875-77 (BAR/D.2), whose members included, apart from Barlow himself, Sidney Coupland, Rickman Godlee, William Smith Greenfield, Robert Parker, and William Allen Sturge.

Most of Barlow's private patients' records have not survived, though there is an index to his private patients' books, covering the years 1876-1918 (BAR/F.1).

Scientific and clinical matters are also discussed in Barlow's correspondence, but again this is relatively thin for the period when he was active in research. Barlow's non-family correspondence has clearly been heavily weeded: there are few letters from patients, with the exception of some prominent individuals, such as Mary Curzon, wife of Lord Curzon, Randall Davidson, archbishop of Canterbury, Lord Salisbury and Lord Selborne, and in general it seems that while letters from important or well-known figures have survived those from individuals deemed less important have been discarded. Significant numbers of letters remain however from several of Barlow's regular correspondents, such as the poet, Robert Bridges, Lord Bryce, and William Page Roberts, dean of Salisbury, as well as medical figures like Sir William Jenner and Sir James Reid.

Barlow's personal papers and family correspondence have survived in bulk and form a rich source of material for both his private and family life, and his public career. There are travel journals and sketchbooks from his earlier years, mainly documenting visits to the Continent, 1869-83; correspondence with his parents, brother, wife and children, 1852-1940, including letters written by Barlow from Balmoral, where he served as royal physician intermittently between 1897 and 1899, an eye-witness account of the death of Queen Victoria in 1901 (BAR/B.2/4), and letters and telegrams from court in 1902 during the crisis of Edward VII's appendectomy; and commonplace and scrapbooks compiled in retirement, 1920-37. Also from this period are various temperance notes and addresses.

The archive also comprises letters and papers of Barlow's parents, 1842-87; of Barlow's wife, Ada, including letters from her brother and sisters in India, 1858-80, and to her daughter Helen studying in Darmstadt, Germany, 1905-6; of Barlow's sons, Alan, Thomas and Basil, including letters from the last-named while serving on the Western Front, 1916-17; and notably of his daughter Helen, including correspondence with Archbishop and Mrs (later Lady) Davidson, 1910-35, and letters from Sir John Rose Bradford and his wife while serving in the Royal Army Medical Corps in France, 1914-19. Helen Barlow's papers also include records of three charities with which she was associated: the University College Hospital Ladies Association, 1900-50, the Southwark Boys Aid Association, 1914-36, and the Quinn Square [Southwark] Social Centre Society, c. 1935-1951. Finally there is a handful of letters to Andrew Barlow, Sir Thomas's grandson, mainly relating to articles he wrote about his grandfather, 1955-81.

Although the collection is by no means comprehensive, there are interesting records of many aspects of Wilson's career.

Section A. Biographical: Brings together material relating to obituaries, tributes, honours and awards. Includes Wilson's account of his First World War experiences and his assessment of his scientific publications. Section B. Research: Although not extensive, provides documentation of a number of Wilson's principal interests including the Salmonella group of bacteria and milk hygiene. There are three laboratory notebooks with experimental data covering the period 1919-45. Section C. Public Health Laboratory Service (PHLS): Relates chiefly to the unpublished history written by Wilson after his retirement as Director of the PHLS. There is also a little material relating to laboratory design and equipment and PHLS personnel. Section D. Lectures and publications: The most substantial in the collection. There are records of Wilson's lectures for a period of forty years from 1944, extensive documentation of the later editions of Principles of bacteriology and immunity, and editorial correspondence and papers for the British Journal of Experimental Pathology and the Journal of Hygiene. Section E. Societies and organisations: Documentation of Wilson's association with ten British organisations including the Medical Research Club, Medical Research Council and Veterinary Club. The Medical Research Council material relates to the Working Party on Tristan da Cunha which was set up to supervise medical investigations when the inhabitants were evacuated to Britain after the island's volcano erupted in 1961. There is also material relating to the Research Foundation, Chicago, which specialised in tuberculosis research, on whose medical advisory committee Wilson served. Section F. Visits and conferences: Records of a number of overseas trips in an advisory capacity for the World Health Organisation, including to Ethiopia 1964, Iraq 1965, Iran, Sudan and Egypt 1971 and the Philippines 1972, and records of international microbiology congresses. Section G. Correspondence: Although not extensive, includes a chronological sequence of scientific correspondence, 1930-1987, Wilson's collection of autograph letters addressed to Topley and himself, and references and recommendations. Section H. Photographs: Photographic records of Wilson, colleagues, conferences and PHLS laboratories. Section J. 'Biographical History of Bacteriology': Manuscript of Wilson's history, with correspondence about publication.

The archive spans Browne's career from school onwards, but the core series of records focus on his work as a medical missionary at the BMS hospital in Yakusu, Belgian Congo (now the Democratic Republic of Congo). Section B comprises records for the period 1938-1958, including registers of leprosy sufferers, case records and photograph albums documenting various symptoms. Section K contains further photographs (mainly clinical) for the period 1938-1977, the most important series of which dates from Browne's time at the Baptist Mission Hospital and comprises over 900 negatives and prints together with supporting documentation, 1954-1958.

Section C contains a small number of files compiled by Browne during his research into leprosy, yaws, onchocerciasis and ainhum, 1946-1983. Particularly notable are the files on the anti-leprosy drug B663 (now known as clofazimine), into the use of which Browne conducted pioneering studies whilst director of the Leprosy Research Unit, Uzuakoli, Eastern Nigeria, 1959-1966.The remaining records comprise personal and biographical material, 1923-1985 (section A); general subject files containing correspondence, reprints etc. on a wide variety of topics, 1948-1986 (section D); writings by Browne, 1935-1985 (section E); records of Browne's involvement with the International Leprosy Association, 1909-1985 (section F) and various other organisations, 1959-1986 (section G); records on foreign visits, 1965-1985 (section H); and a few files on religious matters, 1959-1984 (section J).

Agreements for printing and publishing the international catalogue of scientific literature between the Royal Society and Messrs Harrison and Sons, 1901-1911.

Biographical material includes the draft of Mourant's autobiography, Blood and Stones published after his death in 1995, together with the correspondence and papers Mourant assembled while writing it. There is also documentation of Mourant's education at Victoria College Jersey and at Exeter College Oxford. The latter includes notes on lectures 1922 - ca 1926. Documentation of Mourant's career, honours and awards is patchy, although there is material relating to his search for employment in the early 1930s. There are pocket diaries spanning 1915-1982, with a fairly continuous sequence 1922-1961. Biographical material also includes extensive family and personal correspondence, much of which dates from or relates to the German occupation of Jersey or shortly thereafter. Mourant's other documented interests include his membership of the Methodist Church and his political affiliations, the League of Nations Union in particular.

There is a little material relating to Mourant's early career with the Geological Survey 1929-1931, miscellaneous material relating to Mourant's service with the MRC's Blood Group Reference Laboratory at the Lister Institute and the Nuffield (later Anthropological) Blood Group Centre at the Royal Anthropological Institute, London, and more extensive but uneven coverage of the Serological Population Genetics Laboratory. Although there is some documentation of the foundation of the Laboratory 1964-1965 and of its staff, the surviving material consists chiefly of correspondence and papers relating to Mourant's largely successful efforts to find continued funding for the Laboratory 1969-1977. Haematological research material, though not extensive, covers Mourant's work in a number of areas from research on blood serum in the mid-1940s to the mapping of blood groups in the 1960s and 1970s. There are early research notes, correspondence and papers relating to student and other expeditions undertaking blood group and physical anthropology research and some MRC material assembled by Mourant relating to projects in which he had an interest. The largest group of research papers, however, is maps and data produced during preparation of the second edition of The Distribution of the Human Blood Groups. There is a chronological sequence of drafts and correspondence relating to Mourant's publications, 1929-1991, with extensive material relating to editions of The Distribution of the Human Blood Groups and to The Genetics of the Jews (1978). There is also editorial correspondence relating to publishers and journals, chiefly invitations to review books or referee papers and an incomplete set of offprints. There is correspondence and papers relating to some of Mourant's lectures and broadcasts, most notably the lectures on blood groups given at the Collège de France, Toulouse, 1978-1979. Societies and organisations material is not extensive, and is confined to brief documentation of only a few of the societies and organisations with which Mourant was associated. It includes professional and geological bodies as well as haematological, biological and medical organisations. Visits and conferences material covers the period 1960-1987. It is not comprehensive, though there is also considerable documentation of Mourant's visits and conferences in the papers he assembled in the course of preparing his biography and with lectures material. Mourant's correspondence is extensive. Its complexity reflects Mourant's organisation of the material, the bulk of which was found in three main series: 'Foreign 1965-1977', 'Biological' and 'Geological', together with a fragment of a fourth series 'Home 1965-1977'. Principal correspondents include C.C. Blackwell, B. Bonné, O.J. Brendemoen, V.A. Clarke, L.L. Cavalli-Sforza, A. W. Eriksson, T.J. Greenwalt, J.K. Moor-Jankowski, T. Jenkins, W.S. Pollitzer, D.F. Roberts, J. Ruffié, D. Tills and J.S. Weiner.

The collection covers most aspects of Williams' life and career after 1939. Papers from her work with the British Colonial Service in Ghana, 1928-1936, were largely lost during transit to her next appointment in Singapore, but the typescript copy of her 1935 report The mortality and morbidity of the children of the Gold Coast is extant. Many papers relating to Williams' work with the British Colonial Service in Singapore, 1936-1941, were lost during the Japanese invasion, but she took a few files into Changi jail, where she wrote up the report An experiment in health work in Trengganu in 1940-1941. Notebooks, correspondence and writings made during her internment, when she was appointed as camp nutritionist by her fellow women prisoners, are also in the collection. Post-war papers cover most aspects of Williams' work, including positions with the World Health Organisation, the American University at Beirut and Tulane School of Public Health, as well as correspondence and collected reprints relating to work carried out in 'retirement' at Wyndham House, Oxford.

Reports on scientific papers submitted for publication to the Royal Society from 1832 to date (Peer Review). The referees were appointed to advise the Committee of Papers, and were drawn from appropriate subject disciplines within the Fellowship. Referees Reports vary in content between terse notes recommending acceptance or rejection to long monographs devoted to the subject under review. Much of their interest derives from the comment of one scientist on the work of another, for example Michael Faraday on J P Joule (RR.3.154,158) or Sir Oliver Lodge on Ernest Rutherford (RR.13.106).
