Letter from Howard Walter Florey to O S Franks, Ministry of Supply, London Thanks for letter - understands that Ministry of Supply is unable to give Russians information about deep fermentation because of complications with American interests - appears that Ministry is unable or unwilling to make efforts to see if Russians can be given information on any parts of the process for preparing penicillin - comments on this - seems Ministry has no intention of seeing Dr Borodin or the Russian Trade Delegation - does not think he should be expected to explain the situation to Borodin - comments on this - appears to be a lack of initiative in the commercial field, which is prejudicial to British interests - comments on this - wants to know what the Ministry intends to do with regard to Borodin. 7 March 1946
