Letter from Howard Walter Florey to H W Long, Peppard Farm, Henley-on-Thames Discovered in pig over 7 years old that disease of the arteries was present, which was almost identical with that occurring in man - is trying to collect a number of pigs, if possible not less that 5 years old - asks if Long has any suitable pigs he would be prepared to sell - comments on this - might be able to arrange experiment which should throw light on cause of this disease in man - should be grateful for help. 20 October 1960
