Letter to Harvey Cushing from William Osler, From the Regius Professor of Medicine, Oxford, Oxfordshire, England. Sorry not to have seen his exhibit. Sorry in a way that Heger asked for postponement, as Spielmann has his material ready. They are not doing very much at the Historical Section. They will do this month a big book exhibit on the subject of naval and military hygiene. Glad that he will come to work. Thinks that they would be delighted to have him in the American Hospital in Paris. Mentions that they did not have many interesting cases in neurology. Hopes that the Government will open a special hospital for neurological cases. The frost bites are interesting, details about them. He has been really active in buying books for his library, owing to Edmund Boyd Osler's generosity. The last book he got in 1914, is the Aldine Aristotle, 1495. Comments on Revere's bookplate. The latter joins the Universities and Public Schools Regiment. Birkett and Campbell Howard are anxious for him to join the McGill Contingent. Deplores that his studies have been interrupted. He has found himself and will be happy in the literature course. Civilities.
