Chambre Introuvable (Fr., 'the chamber the like of which is not to be found again') was the name given to that Chamber of Deputies in France which met after the second return of Louis XVIII. (July 1815), and which, by its fanatical royalty, began to throw the country and society anew into commotion. The name was given to it by the king in his gratitude (though some think even he spoke ironically); but it soon came to be used sarcastically for any ultra-royalist assembly.
