Antoni Wróblewski, co-founder of the Arboretum in Beńkowa Wiśnia (Fredrów) near Lwów, and later founder of the Arboretum in Kórnik, in his early years spent time in Paris, and specifically, at the National Museum of Natural History. This article adds to the many known documents regarding Wróblewskiʼs study and work in Paris. Two of his letters were found in the Museumʼs archives, addressed to the mycologist, Louis Mangin, in whose laboratory he worked for half a year. The letters regard the publication in the Museumʼs periodical a list of fungi collected by Wróblewski in the Jardin des Plantes.
