Letter from Howard Walter Florey to J M Walker, Worcester College, Oxford Thanks for letter about Pitt Rivers - comments on course in Bacteriology and Pathology, which is designed for those who have done Honours School Physiology - Walker must decide whether Pitt Rivers is capable of doing the course and keeping up his physiology for the first BM - comments on this - should warn Pitt Rivers of difficulties people who have not passed first BM, have in doing course and tell him it is an undesirable practice. 7 January 1954
