We will consider in this second part of our study the relations between medicine, music and Freemasonry, after the condemnation of the animal magnetism of Mesmer at the end of the reign of Louis XVI, from the Consulate until the end of the Third Republic, political regimes during which appear, both in the medical field and in the musical, and in particular, in the field of mental medicine, new currents of thought formulated by new doctors and musicians French or foreign often active in Paris during the different political regimes that our country has experienced since the Revolution of 1789. The institutions of the Ancien Régime, such as the Royal Academy of Music, the Faculty of Medicine or the Royal Society of Medicine which had been abolished by the Convention, will then be gradually re-established under other names: Conservatoire National de Musique, École de Santé de Paris, Académie de Médecine, Muséum national d’histoire naturelle which are still in operation nowadays. In addition, from the middle of the 19th century, several learned societies, such as those in the field of mental medicine, will continue to work in the Société Médico-Psychologique, which is still active at the beginning of the twenty-first century.
