Papers of Paul Belloni du Chaillu, 1864, comprise route notes, astronomical observations and calculations, Gabon, 1864; letter from Acra, 25 Aug 1863 and letter from Fernand-Vaz, 7 April 1864 reporting on journey to, and residence on, Fernand-Vaz river and library MSS letters, chiefly of a personal nature, to Sir George Black during the years 1848-1878.

Records of central administration of the Post Office Telegraphs and Telephones (later Post Office Telecommunications) including records of the Post Office Board (including meeting papers TCB 54), Post Office Advisory Committee and other central functions.

The records concern both strategic telegraphy and telephony activities, such as policy, planning, legal papers (including on the takeover of the National Telephone Company) and routine reporting, and central operational activities including personnel and communications (including Joint Production Council publications, staff magazines, press notices, media coverage and training school and studio photographs).

These central administration records also include the minuted papers relating to telecommunication services 1889-1977 that, for various reasons, fell outside previous archival transfer. The subjects in these minuted papers (TCB 2) include satellite communications (Early Bird), international telephone services, policies toward staff and unions, telephone information services (including ship telephone services, roads and weather, teletourist service, speaking clock and the Santa Claus service), and technological developments (including telephone kiosks, the answering machine, "Amplifying Telephone" and "Laryngaphone").

Reports of Thomas Lauder Brunton's lectures on therapeutics and notes from a lecture on chloroform with three fragments of lectures on eye affections, on the effects of alcohol, and the effect of drugs on the brain given at St. Bartholomew's Hospital, 1892-[1895].

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).

Manuscripts from the collection of the British Medical Association, formerly held in the BMA Library, Tavistock Square, London. The manuscripts were numbered and catalogued at the BMA, with two exceptions among these papers - however the numbering of surviving documents is not consecutive, so that the original collection must have contained at least 26 catalogued items and an unknown number of unrecorded acquisitions. Former BMA MSS.1-6 (transferred at the same time as the manuscripts described here) are now GC/140; one fugitive BMA manuscript was purchased separately and is now MS. 6881. The location of the remainder is not known. The contents mainly comprise transcripts of medical lectures and case notes.

Papers of the British Journal of Surgery, 1913-1943, comprising minutes, accounts and photographs of the Editorial Committee and Sub-Committee, 1913-1922; and minutes, accounts and correspondence of the Editorial Committee and Sub Committee, 1922-1943.

Papers of Gertrude Margaret Lowthian Bell, 1905-1924, comprises twelve notebooks containing archaeological notes, plans of churches and other sites; records of inscriptions including those from Turkey, Iraq, and Syria; one notebook and folders containing astronomical observations from Arabia, 1913-1914 and a notebook by Lesley Gordon for an exhibition at the University of Newcastle, 1994.

The papers include laboratory notebooks dealing with Bawden's research on various plant viruses, and in particular his collaborative work with N.W. Pirie and with A.A.P. Kleczkowski. There is also a detailed exchange of correspondence with Pirie on research in progress, 1937-1940. (Pirie moved to Rothamsted as Virus Physiologist in 1940 when Bawden became Head of the Plant Physiology Department.) There is a wide range of correspondence, with individuals and institutions. It deals with scientific research and problems including viral nomenclature, lectures, conferences, publications, Bawden's reports on research projects, grant applications and appointments. The correspondence relating to Bawden's overseas visits as adviser or lecturer is mainly after 1958 and is sometimes accompanied by Bawden's reports.

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.

Minute books of the Council and Executive Committee of the Association for the Advancement of Medicine by Research, with inserted loose papers, from its formation in 1882 until 1892; minutes of the sub-committee on the Promotion of Research, 1882-1883, and letters to Stephen Paget, 1891-1892.

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.
