Letter from W P MacArthur, Advisory Editor, British Medical Bulletin, Davies Street, London to Howard Walter Florey Says that W D Paton has suggested electron spectroscopy as a subject for an issue of the Bulletin - would like Florey's opinion whether or not there is sufficient material for a satisfactory symposium - Bulletin is sent to countries which have no possibility of obtaining electron microscopes in the near future. 10 March 1960
