Records of the Malaria Therapy Unit, Horton Hospital, including patient casebooks, 1931-1962; patient ward books, 1949-1950; malaria documentation books, 19-- -1966; indigenous malaria subject files arranged by location, 1917 - 1962; Public Health Laboratory Service correspondence and malaria case questionnaires, 1966-1979; mosquito surveys of places in Britain arranged by place and mosquito nuisance subject files, 1920-1968 and research files, 1910 - 1963, including notes on best practice in malaria therapy, lecture scripts, malaria on ships, mosquito identification and control, correspondence, cuttings from newspapers and journals and reviews of work by researchers at the Unit.

Journal kept by John Gallop during the building of the MRC Cyclotron Unit, Hammersmith, 1949-1956, plus reports, correspondence and photographs, regarding the MRC cyclotron and many in American institutions. The 'MRC Policy' files contain reports and correspondence generated during the planning and execution of the cyclotron project, and give a good picture of the background negotiations as well as the day-to-day administration. Gallop's tutorial to the Stafford Hospital Postgraduate Medical School (G.1) summarises his view of the process. Both Gallop and J W Boag sent detailed reports of the cyclotrons which they visited in the USA in 1949-1950 (C.1-6), which Gallop prepared for publication (C.7) and lectures (C.8). The correspondence in Sections D and E contains further reports, and the personal correspondence (Section F), especially the letters from Boag, includes further thoughts on cyclotron development and use.

Material relating to Stuart Craddock's research while working with Alexander Fleming, 1909-2000, in particular on penicillin and acne, a personal manuscript memoir of Fleming, and correspondence with Fleming, Lady Fleming, Ronald Hare, Prof F Bustinza of Madrid, Norman Heatley and others, also some personalia.

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.

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.

The records cover the period 1927-1993, although the majority date from the 1940s to the 1970s. Notable series include general correspondence with colleagues world-wide, 1935-1984; Dr Race's research papers on human genetic markers, late 1930s/early 1940s; files of correspondence, research notes, pedigrees etc. on blood grouping investigations, 1942-1993; and a comprehensive collection of photographs recording Medical Research Council Blood Group Unit staff at work and play, 1927-[1980s].

Papers of the Medical Research Council Medical Cyclotron Unit (MRCMCU), 1934-1961, comprising records relating to the Radium Beam Therapy Research Committee, 1933-1945; and records, including case registers, of treatment carried out using the radium beam and linear accelerator, 1934-1960.

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").

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.
