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.

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.

Carbon copies of Martha Marquardt's transcripts of Paul Ehrlich's copybooks, 1898-1915, made by her during the early 1950s. There are 6 series, representing both copies of letters sent by him, and notebooks. There are not complete sets of transcripts for all of these: in some cases the originals themselves appear to no longer exist. Users should be aware that, according to a letter from Dr E A Underwood, Director of the Wellcome Historical Medical Museum, to Gunther Schwerin, 25 Mar 1963 (WA/HMM/CO/Eau/13), there are some misreadings by Marquardt of scientific terms in the originals, as, although she was capable of deciphering Ehrlich's writing, she was not herself a scientist. The originals are now in Boxes 4-22, 27-27A, 28-28A, 29-36 in the Paul Ehrlich Collection at the Rockefeller Archives Centre, and another set of transcripts in Boxes 80-86 there.

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.
