Two letters to the editor. In the first, the "physicist" Boret relates that a "newly-fashioned physicist", Rodolphe Jossier, wishing to make figures, trees and stones speak in the garden of Augny, had hidden an accomplice in a buried barrel connected to a figure by a tin pipe: the "invisible" soon stopped answering and was found asphyxiated, then revived; Boret refers anyone wishing to make figures speak to the article on speaking-trumpets and on "Figures et bustes parlans" in the second volume of Guyot's Récréations physiques et mathématiques (p. 332 ff.). In the second, R. Charles (Charles Rouy) claims the idea of staging on the Champ-de-Mars or another open plain the experiments in acoustics, invisibility and oracles shown in his salon in the passage Longueville, welcomes the emulation of his rivals, and stakes his priority on a project for instantaneous acoustic communication between two people, one in Versailles and the other in Paris. Full transcription and Italian translation.
