Filon, Augustin (1920). Recollections of the Empress Eugénie. London: Cassell and Company, Ltd. s. 74. Henta March 29, 2013. «To-night [during the "white overalls" riots following the 1869 elections], gala soirée in honour of the Queen of Holland and the Grand-Duchess Marie of Russia.... Everyone seems anxious and ill at ease, and many throw involuntary glances at the windows which look on the Place du Carrousel, over which an angry mob is swarming. Waldteufel's orchestra plays its most entrancing waltzes, and five or six couples venture on the floor. Waltzing, to-night, is an act of loyalty to the Empire.»
