IX. LOUIS LUCIEN (1813-1891), son of Lucien Bonaparte, was born at Thorngrove, Worcestershire, England, on the 4th of January 1813. He passed his youth in England, not going to France until 1848, when, after the revolution, he was elected deputy for Corsica on the 28th of November 1848; his election having been invalidated, he was returned as deputy for the Seine in June 1849. He sat in the right of the Legislative Assembly, but had no direct part in the _coup d'etat_ of his cousin on the 2nd of December 1851. Napoleon III. named him senator and prince, but he took hardly any part in politics during the Second Empire, and after the proclamation of the Third Republic in 1870 he withdrew to England. There he busied himself with philology, and published notably some works on the Basque language: _Grammaire basque, Remarques sur plusieurs assertions concernant la langue basque_ (1876), _Observations sur le basque Fontarabie_ (1878). He died on the 3rd of November 1891, leaving no children. 10. Pierre. X. PIERRE NAPOLEON (1815-1881), son of Lucien Bonaparte, was born at Rome on the 12th of September 1815. He began his life of adventure at the age of fifteen, joining the insurrectionary bands in the Romagna (1830-1831); was then in the United States, where he went to join his uncle Joseph, and in Colombia with General Santander (1832). Returning to Rome he was taken prisoner by order of the pope (1835-1836). He finally took refuge in England. At the revolution of 1848 he returned to France and was elected deputy for Corsica to the Constituent Assembly. He declared himself an out-and-out republican and voted even with the socialists. He pronounced himself in favour of the national workshops and against the _loi Falloux_. His attitude contributed greatly to give popular confidence to his cousin Louis Napoleon (Napoleon III.), of whose _coup d'etat_ on the 2nd of December 1851 he disapproved; but he was soon reconciled to the emperor, and accepted the title of prince. The republicans at once abandoned him. From that time on he led a debauched life, and lost all political importance. He turned to literature and published some mediocre poems. In January 1870 a violent incident brought him again into prominence. As the result of a controversy with Paschal Grousset, the latter sent him two journalists to provoke him to a duel. Pierre Bonaparte took them personally to account, and during a violent discussion he drew his revolver and killed one of them, Victor Noir. This crime greatly excited the republican press, which demanded his trial. The High Court acquitted him, and criticism then fell upon the government. Pierre Bonaparte died in obscurity at Versailles on the 7th of April 1881. He had married the daughter of a Paris working-man, Justine Eleanore Ruffin, by whom he had, before his marriage, two children: (1) Roland Napoleon, born on the 19th of May 1858, who entered the army, was excluded from it in 1886,
