Letter from Howard Walter Florey to N V B Marsden Pleased Marsden has done so well in Sweden that they are trying to get him a Rockefeller Foundation grant - has not seen much of Marsden's work for many years - Marsden did not establish a very good reputation at Porton - comments on this - suggests that Professor Theorell write to him about Marsden's work - comments on this and on Marsden's plan to investigate ion and molecular transport across membranes. 13 December 1954
