The symposium was organised by the Australian Academy of Science and held under the auspices of the International Union of Pure and Applied Chemistry (IUPAC). Abraham, with Guy Newton, gave a lecture 'Degradation of cephalosporin C'. Includes a copy of the Symposium Handbook interleaved with pages of rough manuscript notes, some in Abraham's hand.

F.3: Conference (Gordon research Conference) on Medicinal Chemistry, Colby Junior College, New London, New Hampshire, USA, 30 July-3 August 1962. Abraham gave a lecture 'Biochemical and Microbiological Studies on Derivatives of 7-Amino-cephalosporanic Acid'. Includes a Programme with manuscript notes by Abraham on a number of pages and a letter arising, July 1962.

F.4: Cephaloridine Conference, New College Oxford, 13-16 March 1967. The conference was arranged jointly by the Fellowship of Postgraduate Medicine and Glaxo Laboratories Ltd.

F.5-F.10: Visit to the USA, April 1967. Abraham was invited to give lectures at the University of Wisconsin (one of a series of Rennebohm Lectures) and at a 'Penicillins and Cephalosporins' symposium held during the annual meeting of the American Academy of Pharmaceutical Sciences in Las Vegas. F.5-F.6 contain material relating to the Rennebohm Lecture by Abraham, University of Wisconsin, 6 April 1967. The title of the lecture was 'Penicillins and Cephalosporins - their chemistry in relation to biological activity'. F.7-F.8 contain material relating to the 'Penicillins and Cephalosporins' symposium, Las Vegas, 9-14 April 1967. The title of Abraham's lecture was 'Penicillins and Cephalosporins - their chemistry in relation to biological properties'. F.9 contains correspondence arising from the two lectures and from the visit to the USA in general, November 1966-September 1967.
