Work done while Hodgkin was still an undergraduate. See also MS. Eng. c. 7941/4.

Notes, diagrams, calculations, including three page manuscript letter from Hodgkin describing her research on vitamin B1 hydrochloride, sent to R.A. Peters in answer to enquiries from him. Included here is a copy of 'Crystal structure of vitamin B1 hydrochloride', with J.D. Bernal, Nature (London, 1933) (Bibliog. 124).

Three page typescript with manuscript heading, perhaps by Joseph Needham. Section on 'crystal physics applied to biology' indicates intended use of X-ray crystallographic analysis.

Brief one and a half page note, describing Hodgkin's first successful crystallisation of insulin with a sample supplied by Boots Pure Drug Company and passed on to her by R. Robinson (Ferry pp.109-112). Pages are numbered 8 and 9, perhaps from a Departmental Report. See also MS. Photogr. c. 501/6.

Seven page typescript and manuscript draft, a fuller account of the experiment and the first paper to be published under Hodgkin's name alone (Ferry p.114). With a letter arising.

Twenty-five page draft (see also MS. Eng. c. 5590/7 in the main Hodgkin papers). Enclosed here are related reports on research in Leeds by W.T. Astbury and Florence Bell (1941) and in Cambridge (on the crystal structure of haemoglobin) by M.F. Perutz and colleagues (1942-1943).

Drafts and headings for a paper or publication. Hodgkin wrote and lectured frequently on the subject and it is not possible to assign a firm date.

Diagrams, Patterson maps, one page note on the work by Hodgkin. Some of the photographs are dated 1981, but the work predates this by many years.
