Letter to H.A. Bruce from William Osler, 13, Norham Gardens, Oxford, Oxfordshire, England. Osler writes that he only heard of the Canadian Army Medical Corps squabble after returning from Brodie's funeral. He did think it unfair that men who were under Gen. G.C. Jones would be appointed to report on the work of his department.
