Letter to William Sydney Thayer from William Osler, 13, Norham Gardens, Oxford, Oxfordshire, England. They have had an anxious time. His brother Frank lost his only son, who had been Shaughnessy's private secretary. Norman Gwyn has been doing good work at No.1 General near Bourgogne. Revere is with his battery in the Somme. The chief occupation seems to be the exchange of gas bombs. Mentions that his son has taken to the practical work kindly but as a disciple of Walton, the whole business is very distasteful. Word about Miss Louisa Parsons' death. Will write to Sister Rachel about her. Confides that in spite of the interesting things he sees everyday, he get very tired of the wounded and of sepsis. Mentions the Royal Commission on Welsh Universities and of Haldane. Confidences on his anxiety for his son.
