IT can scarcely be doubted that, by coming genera tions, the Great War will be held to mark an epoch in the history of medicine. Taking medicine in its widest sense, as a calling centred on the preserva tion of life and the mitigation of human suffering, its historian will have to go back to the day of Lister for anything comparable to the rapid and marvellous advance that was made during the War. The two cases are certainly widely different. Lister, like Pasteur, stands in solitary grandeur on the plains of peace, conferring after laborious days the splendid and enduring gift which his rare genius had put into his hands to bestow. In the case of the War, many great names are involved it was team-work on a titanic scale. No one man among them stands as Lister stood among his fellow labourers. But moving about among the soldier and civilian members of the medical profession who are most competent to judge, the impression is left that if a name were to be chosen for the seat of honour, none could come before that of Sir Alfred Keogh, whose death at the age of seventy-nine years occurred on July 30.
