Letter from F C [Frank Campbell] MacIntosh, Department of Physiology, McGill University, to Dr L G [Leonard George] Goodwin, Shepperlands Farm, Park Lane, Finchhampstead, Wokingham, Berkshire, England Goodwin is quoted in Hugh Blaschko's memoir of von Euler as saying that liver sympathin experiments were completed before the war, although published after. He finds this interesting and asks when Gaddum changed his mind on the subject, whether in 1939 or after von Euler extracted noradrenaline from sympathetic nerves. He would like to publish a brief comment on the matter in a book he is working on. 21 March 1986
