Letter from Howard Walter Florey to John R Squire, Department of experimental Pathology, Medical School, Birmingham Thanks for invitation to examine in pathology at Birmingham - should have liked to be able to do this - stimulating to find out what is being done at other universities - at present is not sure what his commitments will be - has to go to Australia in 1957 and this might be in June or September - regrets he cannot accept invitation. 30 October 1956
