[Sources for the history of malaria in the historical archives of the Accademia Dei XL and the Accademia Dei Lincei].

A research has been performed in the Historical Archives of the Accademia dei XL and the Accademia dei Lincei, to verify the presence of documentary sources concerning the activity of some malariologists members of the above mentioned institutions. During the search, the Authors found out an envelope sealed out by Giovan Battista Grassi in 1925. At the moment, it is not possible to specify what kind of material the envelope keeps, because of the necessity to wait the deliberation of the classes, and consequently the beginning of the Academic courses.
