Letter from H R Dean, Department of Pathology, University of Cambridge to Howard Walter Florey Was sorry not to see Florey in London - is interested in publications on Florey's work - surprised he was asked to be chairman of the Penicillin Clinical Trials Committee - important that further trials be carried out with the benefit of Florey's experience and that Florey should be in touch with all penicillin work. 16 March 1943
