Letter from Howard Walter Florey to S C Dyke, The Royal Hospital, Wolverhampton All penicillin supplies are now controlled by the Penicillin Clinical Trials Committee of the Medical Research Council - unlikely that Dyke will be able to get any penicillin as nearly all the supplies are going to the army - Committee will probably not want to treat cases like Dyke's with the limited supply available. 20 November 1943
