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.

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.
