Letter from Sir Almroth Wright to Leonard Colebrook Manuscript letter from Almroth Wright to Leonard Colebrook written soon after Wright's return to the hospital at Boulogne from the Front. Wright discusses his work on the 'mass experiment on inoculation at the Front', which is producing 'interesting results'. He states that he is in only Boulogne to retrieve an anti-gangrene vaccine and stores, before returning to the Front. Wright also discusses Parry Morgan [a member of his team], and Morgan's resignation from his position, seemingly due to Morgan's incompatibility with his colleagues. A typescript copy of the letter made by Leonard Colebrook is included. 12 January 1916
