Letter from Howard Walter Florey to John F Fulton, New Haven, Connecticut Says it is very difficult to write about penicillin for the lay public - comments on activities of St Mary's Hospital and on the elimination of Oxford from the penicillin picture as far as the lay public are concerned - has amended Fulton's penicillin article and is sending notes - says book (Antibiotics) is progressing slowly - hopes book will clarify the situation. 26 July 1945
