The papers consist primarily of Daly's meticulous records of experiments, covering the period 1919-1965, in a series of large notebooks, all indexed by him, some of which represent compilations of material gathered over many years from a variety of sources. There is also correspondence with, and biographical information regarding, several eminent physiologists including Sir Edward Sharpey-Schafer and Sir Charles Sherrington. William Sharpey is represented by five autograph letters to Sir Charles Lyell, 1858-1871.

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.

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.
