Letter from Howard Walter Florey to Duncan Guthrie, Polio Research Fund, Vincent Square, London Discussed question of research fellow in virology with Dr Gladstone - valuable to expand work on viruses if suitable person could be found - could not receive fellow unless they had 12 months' notice - wonders if it might be better to establish a few permanent posts for people who have proved their worth - comments on this - reluctant to accept Fellow if is obliged to look after him when Fellowship has terminated. 25 May 1960
