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.

These papers show Davy's first ideas for an electric telegraph from his early sketches in 1836 of a frictional electric telegraph to one worked by electromagentism which he developed 1836-1839. His first patent was lodged in 1837 in opposition to Cooke and Wheatstone's first patent. The papers indicate his efforts to find a purchaser for the patent rights and to establish a company to develop the telegraph. He made agreements with several business men but none of these arrangements bore any fruit. He also negotiated with the railway companies and demonstrated the telegraph for them. The papers record the efforts of his father, Thomas Davy, and several others, to continue Davy's negotiations with the railway companies and the arrangements which were made to re-exhibit a working model of the telegraph. The papers also relate to the sale of the patent to the Electric Telegraph Company in 1847. Fahie's memoir on Davy is included in the papers.

Correspondence, comprising a private letter book 1863-1867, and correspondence and reports relating to the laying of the West Indies cable 1869-1870. The private letter book contains bound letters refering to cable laying in India, the West Indies and Brazil, resistance testing to find faults on cables in a long letter to Fleeming Jenkin, mining companies with which Bright was involved, the Steam Engine Improvement Company and the Railway Lubricating Company. The volume contains many blank pages and some pages have been cut out. Some letters are illegible because of the very faint copy, and there appears to be a double impression on some pages suggesting that a second letter may have been copied onto the same page. The loose correspondence relates to the setting up of the West India and Panama Telegraph Company and includes reports and correspondence concerning the laying of the cable. Some of the papers were used in a court case in 1872 between the West India and Panama Telegraph Company and the India Rubber Company for failing in their contractual obligations.

Letter from the Countess Vernède de Corneillan of 46 (ancien) rue de Rivoli au coin de la rue Castiglione, Paris to [Charles] Babbage, 10 Sep 1854. 'Monsieur Babbage m'a fait passer la lettre que vous avez eu la bonté de lui écrire au sujet d'inventions de M. [Philippe] de Girard … Je prends la liberté de vous récrire a çe sujet, car cette affaire est d'une haute gravité pour notre famille … Vous dites …que le "moyens de M. de Girard sont ingénieux mais que le même effet a été produit par des moyens plus simples, et tellement analogues qu'il me serait difficile de prendre un brevet"'. Saying that if this sentence concerns 'les greniers à blé', she would like to ask certain questions: (i) whether the process analogous to that of Girard is patented in England; (ii) under what name; (iii) at what date and since when; (iv) what are the differences that make it simpler and what are the things analogous to it? Excuses her importunity on the grounds of the matter's important to the memory of her uncle.

The Register Books contain copies of scientific papers submitted to the Society - the original documents may be found in the Classified Papers. The papers were transcribed in order to establish their precedence for a particular discovery or idea. Therefore not all communications to the Society were registered in this manner, but only those judged to contain some significant material. Dates as listed are those in which the paper was communicated to the Royal Society; dates of writing, where given, are included in the description of each paper. Many of the these papers were published in 'Philosophical Transactions'.

The correspondence, papers and diaries of Sir Charles Blagden. Blagden's papers are interesting on several levels, generally for his close contact with European men of learning, and his relationship with Sir Joseph Banks. Blagden's professional researches are represented by medical notes in the boxed sequence. These are grouped with papers on other subject interests, including linguistics, e.g. a draft Tahitian-English dictionary, compiled from conversations with Omai, whom Blagden inoculated after Omai's voyage to England with James Cook. Blagden's interest in antiquities and travel is documented by diary entries, as is his intercourse with fellow scientists, particularly those associated with the founding of the Royal Institution.

Files of papers and correspondence relating to the Royal Society's administration of its internal affairs. Currently, the bulk of this material falls within the period 1925-50, although the period covered varies considerably according to subject. At present, the collection forms an important source on the Society's activities during the Second World War, and includes files of the Central Register (Section for Scientific Reseearch) for 1939-1940. Section A of the series contains correspondence of a number of important Fellows; WH Bragg 1935-41; HH Dale 1926-45; ACG Egerton 1939-49; AV Hill 1949-45; FW Lanchester 1942-44; HG Lyons 1939-42; TR Merton 1941-56; R Robinson 1946-50; AC Seward 1932-41; FE Smith 1928-33; HT Tizard 1940

Single manuscript letters or small groups of related documents considered too small to be added to the Manuscripts General series. Includes various document formats. The collection contains all manner of papers by, about or belonging to the Fellows of the Royal Society. Subject matter covers all branches of the sciences and includes non-scientific material. Current accessions are limited to materials not generated by the Royal Society, but acquired by gift or purchase; these usually number less than 10 items per accession. This has not always been the practice, so that the collection also contains relatively large groups of papers, occasionally on Royal Society business.

Copies of the outgoing letters written by the Foreign Secretaries of the Royal Society.

Papers of John Canton.

Papers of and relating to Joseph Priestley, inclusing volume of items relating to Priestley's life, three letters from Priestley, his spectacles, and Diploma and seal awarded in 1780 by Catherine II, Empress of Russia.

A small collection of photostats or photocopies of manuscripts held in other institutions, but of some relevance to the Royal Society and its own Archives. The series largely consists of groups of correspondence, notable letters to Julius Plucker (PH.1) letters of Hevelius, Newton and Flamsteed (PH.2) and of Edmond Halley (PH.3) There are some records of other institutions, including a minute book of the Physiological Society 1876-1892 (PH.9), and copies of Rutherford's correspondence at the Cavendish Laboratory.

The manuscript versions of papers published by the Royal Society in the 'Philosophical Transactions'. The series has many points of interest, which include authors' corrections to manuscripts, and the presence of original illustrations in various media (drawings, watercolours and photographs) bound in the volumes. Not all of the material printed in the 'Philosophical Transactions' relating to Society business survives, but manuscript examples of meteorological observations, lists of presents and annual indexing may be found in volumes 8, 9 and 12.
Papers are usually bound into vellum-covered volumes by year of publication, although a few (volumes 4, 5, 8, 9, 12, 17, 73-75) are loose, boxed items. Several gaps appear in the collection, notably for the period 1825-1839 (volumes 18-22) and any year may lack one or more papers; these omissions are noted at the beginning of each part. Despite this, the series constitutes a large, relatively complete run.

Letters and other Papers of the Hon Robert Boyle. The Letters cover Boyle's correspondence; in addition to the letters by scientists such as Hartlib, Beale, Southwell, Wallis and Cole, the series contains letters from members of Boyle's family (Viscountess Ranelagh in particular). There are 37 letters of Boyle's preserved, and substantial blocks of papers from religious figures such as Robert Sharrock. The Papers cover his philosophical, scientific, theological and other interests, and cover most aspects of his life and works.

The bulk of the collection consists of correspondence: the Singers were clearly vigorous letter writers and both Charles and Dorothea had an enormous number of family, friends and acquaintances. Unfortunately many of their letters were hand written and very few carbon copies survive. Very occasionally an attempt at methodical selection and arrangement is evident: on the whole correspondence had been kept in alphabetical order, and this has been retained in the arrangement of the collection. Dorothea and Charles' correspondence was fairly mixed (reflecting their working life together) with the exception of two distinct groups: correspondence about Dorothea's research on alchemical manuscripts, and later correspondence about her hearing aids.

The main part of the collection centres on the correspondence; this has been grouped together in a self-evident sequence: writings and biographical personal papers follow. Certain of Dorothea's papers remained clearly distinct and these have been kept together. Section E contains a variety of material relating to Jewish refugees, which had been placed on one side by Dorothea after the war for permanent preservation. It has not been listed in detail but sorted into three broad categories. The last section, comprising additional correspondence of the Singers with Sir Zachary Cope, Sir Arthur Salusbury MacNalty and Dr F N L Poynter, is not strictly part of the collection, but these groups of correspondence were given to the Institute to be placed alongside the Singer papers.

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.

Notes on the history of science.

Papers, 1922-1980, of Joseph Henry Woodger, consisting of research and personal notebooks, research files, manuscript and typescript drafts of works, correspondence, photographs and printed material.

Papers of the Arden Philosopical Lectures, c 1775-1800, comprising a volume of manuscript lecture notes titled Philosophical Lectures delivered by Mr Arden at Dursley. The notes discuss topics such as electricity, including the work of Dr Benjamin Franklin with lightning rods. The notes also cover the subjects of air and gases, commenting on the work of Dr Joseph Priestley relating to 'fixed airs' (carbon dioxide), 'inflammable air' (hydrogen), the effects of 'phlogiston' on the air, and 'dephlogisticated air' (oxygen). The volume is undated; Priestley's paper on his experiments with airs and gases was published in 1775.

The papers are extensive covering Faraday's work in science. Details of his work on electro-magnetic induction, the laws of electrolysis and the theory of electro-magnetism are in the form of laboratory notebooks, lecture notes and various publications on experimental researchers in electricity. There are some administrative papers on the Royal Institution of Great Britain including cash books. The correspondence covers his work for the Admiralty and the Corporation of Trinity House whilst acting as Scientific Adviser; they also detail his general communication with people and other organisations. Other items include his book collection, scrapbooks, portfolio of portraits and apparatus. A few lacunae have been identified. There are no documents on his personal life or his work as Professor of Chemistry at the Royal Military Academy, Woolwich.
