|
|
|
(1784-01-24): At the Académie "M. Lavoisier a fait voir une machine destinée à employer l'air déphlogistiquée dans les expériences de chimie et à mesurer la quantité d'air qu'elle dépense et à la graduer à volonté."

|
|
|
(1784-03): Four men from the Faculté de médecine (Borie, Sallin, Darcet, Guillotin) appointed by the king to study animal magnetism. In early April five member of the Académie des Sciences are added (Franklin, de Bory, Le Roy, Bailly, Lavoisier).

|
|
|
(1784-03-20): At the Académie "MM. Meusiner et Lavoisier ont déposé tant à leur noms qu'à celui de leurs collègues un paquet caheté sur un fait nouveau pour etre ouvert le vendredi 2 avril." It was not opened until 24 April.
