Letter to Sigmund Adolphus Knopf from John George Adami, J.H.R. Molson Laboratories of Pathology and Bacteriology Mc Gill University, Montreal, Quebec, Canada. Thanks him for coming helping them. Since he can only give them one day, they prefer him to deliver the Address only in English. Sorry about the trouble he had with the wretched report in the North American newspapers. Wish him success in his case. Mention that he sympathized with Osler at the Fixed Period time but thinks that Osler was paid back for his habit to "jollying". In Knopf's case, he does not feel that way. It harms him and also the Tuberculosis campaign. Civilities.
