SIR,-By the death of Edgar Hartley Kettle in December last pathology, in this country, lost one of its most distinguished exponents, and all who knew him were deprived of a personal friend. We feel sure that those who were associated with him, as colleagues or students in his professional work, or in any other of the activities in which he took part, would desire that his memory should be perpetuated in some suitable form.Kettle's devotion to his subject, and to all that concerned it, including particularly the interests of his students and younger colleagues, was evidenced throughout his professional career. As an original worker, as a director who stimulated the work of others, as a teacher, as a senior member and treasurer of the Pathological Society, and as an active member of numerous committees he played a part that will not be forgotten. In each of the four University schools in which he directed the teaching of pathology-St. Mary's, Welsh National School of Medicine, St. Bartholomew's, and the British Post-Graduate Medical School--he won the admiration and affection of his colleagues and his students. We feel that a fitting tribute to his memory would be the foundation of a Kettle Memorial Lectureship. in Pathology, and that this lecture might appropriately be given annually, in each of these schools in turn.An endowment fund is being collected for this purpose, and we are sure that his colleagues and friends, including many who, though not pathologists, were associated with him in connexion with his pioneer work on silicosis, or in other ways, would wish to be given the opportunity of contributing. It is suggested that individual contributions should not, in most cases, be more than two guineas, and smaller sums will be welcomed.
