Minute book of the Mining and Metallurgical Club, 1910-1916, with a note dated 2010.

Papers of John William Couchman and Harold Seymour Couchman, surveyors, agents to the lords of the manors of Tottenham and Edmonton and civil engineers, 1789-1938. The majority of the papers are those of John William Couchman who was a civil engineer (in particular, apparently, a waterworks expert) and a surveyor and valuer, but a few later ones relate to his successor, Harold Seymour Couchman.

John William Couchman acted as surveyor and agent to the lords of the manors of Tottenham and Edmonton. Most of the manorial documents are valuations for enfranchisement of copyhold property. These cover the second half of the nineteenth and early twentieth centuries, and are arranged alphabetically under the names of the copyholders. There is also, however, a survey of Tottenham manor of circa 1830 and two rentals of quit and waste rents for Tottenham and one for Edmonton, together with correspondence with the local urban district councils over their purchase of manorial waste.

The remainder of the collection consists of documents concerning property of the Sperling family and of others for whom Couchman acted as agent; his own papers relating to various engineering projects - notably that to provide a drinking water supply for Bridgetown, the capital of Barbados, papers concerning the Tithe rent charges for Tottenham (for which he acted as valuer), various sales particulars including one of 1789 for Bruce Castle and Mount Pleasant, and two albums of photographs taken at the end of the last century which are of considerable interest.

This exceptionally interesting collection consists of the archives of a London business family, the Howards, and their relations by marriage, the Eliots. The family were based in London, with homes in the City and various places round about, but they also had property and connections in several other parts of England.

The chief interest of the collection is in its quality as the personal record of a group of prosperous manufacturing and merchant families who were members of the Society of Friends. The Eliots were merchants and their account books, which cover both business and private expenses, together with letters and memoranda, reflect a picture of "City" life in the Eighteenth century. They attended the Change, Lloyd's and Child's and Jonathan's and other Coffee Houses, and dealt with a variety of business including trade overseas in cotton and duck cloth and Cornish tin and invested in "a voyage to Lima" and other merchant shipping ventures (including that of the Tuscany, unfortunately "Taken by the French and carried into Marseilles" in 1757). (See especially numbers 905, 928, 929, 944, etc.).

There is interesting material relating to John Eliot's estates supplemented by John Eliot's letters (e.g. Numbers 988-1011), which also mention a "good season" for pilchards, the decline of the docks at Topsham, the appropriation by the Government of some sugar pans near Exeter to use for French prisoners, etc. John's sister Mariabella also purchased in 1765 Pickhurst Farm, Hayes, Kent (Nos. 376-475).

There are amongst this collection a few letters and papers of later Howards, including an interesting pocket diary in which Samuel Lloyd Howard, grandson of Luke, jotted (unfortunately rather roughly in pencil) memoranda and sketches of impressions of his visit to America in 1854 (No. 1618). At sea his ship rescued the crew of the Hannay of Whitehaven, loaded with salt and flying a distress signal-"lay to and took all off, boy, baggage, chronometer, barometers and all".

At all periods the family kept in close touch with their relations in all parts of the country, including the Hows of Aspley, Bedfordshire, the Paces of Westmorland and London, the Leathams of Yorkshire as well as with fellow Quakers. This gives the collection a national rather than a local interest-indeed the family were not primarily associated with any one locality.

A curious document amongst the collection is a receipt dated 1824 for 8. 15s from R. Smith for freeing Hamma Fie, slave to Bentoo Demba, and signed with the mark of Madeba, Alcaide of "Birkow" (No. 1617/p.12). The Society of Friends Committee for African Instruction supported some missions, and Richard Smith, a friend of Luke Howard, was in Africa in the 1820's.

Quaker marriage certificates, of which there are several examples (eg. Nos. 117, 565, 1273, 1274, etc) give full details of both parties and are signed by members of the Meeting as witnesses. Birth certificates (e.g., Nos. 1275-1286, 1390-1393) give the date of birth and name, and were signed by witnesses to the baby's birth. The Society of Friends was in advance of both the State and established Church in respect of such documentation.

In addition there are papers of John Frost (1803-1840), MS.7691 (4 items), relating either to botanical interests or the Medico-Botanical Society .

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 papers are very extensive though there are some lacunae, probably attributable to Chain's many changes of workplace. The early biographical period is sparsely documented, there are sporadic gaps in the correspondence files, and there is no original documentation of the penicillin research at Oxford (although there are many historical accounts and much correspondence about the history of penicillin). The surviving biographical material provides documentation of the arrangements for Chain to live and work in Britain, later honours and awards and his musical interests, and family correspondence, photographs and press-cuttings. There are very substantial records of his later career at the Istituto Superiore di Sanità and Imperial College, London, including his continuing contributions to biochemical problems such as carbohydrate metabolism, ergot alkaloids, edible proteins and aeration studies. The Imperial College material also contains records of the creation, administration, finance and architectural design of the Biochemistry Department, and developments in the Department after Chain's statutory retirement in 1973. Additional information about Chain's research is available in the documentation of his very extensive consultancy agreements and collaborative work with industrial firms such as Astra, Beechams and Rank Hovis McDougall, and records relating to government, grant-giving and charitable bodies such as the British Heart Foundation, Cancer Research Campaign and Medical Research Council which contributed to the funding of his research. There is much material on Chain's lectures, addresses and broadcasts, and on his extensive travel on visits and conferences, which includes a substantial number of unpublished talks.

An exceptional feature of the Chain papers is the documentation of the large number of Israel and Jewish organisations with which he was associated, especially the Weizmann Institute of Science, where he was a governor for many years and had at one time considered taking up an appointment.

Sharpey-Schafer's correspondence is extensive. In addition to his own correspondence it includes papers of William Sharpey, saved by Sharpey-Schafer after his death, 1836-70 and n.d. There are significant numbers of letters from William Sharpey himself, Sir Michael Foster, Sir John Burdon-Sanderson, Sir William Osler, George John Romanes, Sir Victor Horsley, Sir James Paget, Lord Lister, Sir Charles Sherrington, Sir William Gowers, Thomas Henry Huxley, John Newport Langley, Sir Edwin Ray Lankester, Ernest Henry Starling, Allen Thomson, Sanger Monroe Brown, Sutherland Simpson, Francis Gano Benedict, Harvey Cushing, Albrecht Kossel, Karl Hugo Kronecker, Carl Ludwig, Charles Robert Richet, and Masaharu Kohima.

Material relating to Sharpey-Schafer's career at Edinburgh University includes correspondence on the forced resignation of William Cramer from the department of Physiology on grounds of German nationality, 1914, and papers on the opening of the department of Animal Genetics in 1930.

Other papers reflect various aspects of Sharpey-Schafer's scientific interests, including the history of the Physiological Society (with several letters from Archibald Vivian Hill), artificial respiration and bird migration. There are also numerous letters in response to his controversial address to the British Association in Dundee in 1912, and correspondence on the position of scientists in post-Revolutionary Russia, 1918-21.

There is a substantial correspondence on the various textbooks Sharpey-Schafer wrote or to which he contributed, 1910-34.

Sharpey-Schafer's personal papers include correspondence with his wives and children, 1876-1935, scrapbooks of press cuttings, c. 1899-1930, and a large collection of photographs, mainly portraits.
