Letter from Howard Walter Florey to J M Yoffey, Anatomy Department, The University, Bristol Feels that if Yoffey is to visit with members of group, he should try to organise Oxford haematologists and let them hear Yoffey - no one in department interested in bone marrow - people there who are interested in lymphocyte are dubious about Yoffey's theories - suggests that Yoffey come later and give lecture - comments on this - he has not worked on lymphocyte for many years. 12 October 1956
