she went to seek the Emperor as far as the battlefield of Jena, in 1806, to ask pardon for the two Simeuses and the two Hauteserres involved in a political trial and condemned to hard labor, despite their innocence.  Her bold move succeeded.  The Marquise de Cinq-Cygne gave her husband two children, Paul and Berthe.  This family passed the winter season at Paris in a magnificent mansion on Faubourg du Roule. [The Gondreville Mystery.] In 1832 Mme. de Cinq-Cygne, at the instance of the Archbishop of Paris, consented to call on the Princesse de Cadignan who had reformed. [The Secrets of a Princess.] In 1836 Mme. de Cinq-Cygne was intimate with Mme. de la Chanterie. [The Seamy Side of History.] Under the Restoration, and principally during Charles X.’s reign, Mme. de Cinq-Cygne exercised a sort of sovereignty over the Department of the Aube which the Comte de Gondreville counterbalanced in a measure by his family connections and through the generosity of the department.  Some time after the death of Louis XVIII. she brought about the election of Francois Michu as president of the Arcis Court. [The Member for Arcis.]

CINQ-CYGNE (Jules de), only brother of Laurence de Cinq-Cygne.  He emigrated at the outbreak of the Revolution and died for the Royalist cause at Mayence. [The Gondreville Mystery.]

CINQ-CYGNE (Paul de), son of Laurence de Cinq-Cygne and of Adrien d’Hauteserre; he became marquis after his father’s death. [The Gondreville Mystery.]

CINQ-CYGNE (Berthe de). (See Maufrigneuse, Mme. Georges de.)

CIPREY of Provins, Seine-et-Marne; nephew of the maternal grandmother of Pierrette Lorrain.  He formed one of the family council called together in 1828 to decide whether or not the young girl should remain underneath Denis Rogron’s roof.  This council replaced Rogron with the notary Auffray and chose Ciprey for vice-guardian. [Pierrette.]

CLAES-MOLINA (Balthazar), Comte de Nourho; born at Douai in 1761 and died in the same town in 1832; sprung from a famous family of Flemish weavers, allied to a very noble Spanish family, time of Philip II.  In 1795 he married Josephine de Temninck of Brussels, and lived happily with her until 1809, at which time a Polish officer, Adam de Wierzchownia, seeking shelter at the Claes mansion, discussed with him the subject of chemical affinity.  From that time on Balthazar, who formerly had worked in Lavoisier’s laboratory, buried himself exclusively in the “quest of the absolute.”  He expended seven millions in experiments, leaving his wife to die of neglect.  From 1820 to 1825* he was a tax-collector in Brittany—­duties performed by his elder daughter who had secured the position for him in order to divert him from his barren labors.  During this time she rehabilitated the family fortunes.  Balthazar died, almost insane, crying “Eureka!” [The Quest of the Absolute.]
