Letter from Howard Walter Florey to G A G Mitchell, 42 General Hospital, Middle Eastern Front Says work on burns has been published - would like further data on the healing of fractures and something about secondary suture - regrets no organisation set up early in war to do comprehensive work - has had interesting follow up of fracture case - was due to a penicillin resistant staphylococci - this may occur in up to 4% cases in Middle East. 8 October 1943
