ORLEANS, HENRI, PRINCE OF (1867-1901), eldest son of Robert, duke of Chartres, was born at Ham, near Richmond, Surrey, on Oct. 16, 1867. In 1889, at the instance of his father, he undertook, in company with MM. Bonvalot and Dedecken, a journey through Siberia to Siam. They crossed the mountain range of Tibet, and the fruits of their observations, submitted to the Geographical Society of Paris and later incorporated in De Paris au Tonkin a travers le Tibet inconnu (1892), brought them conjointly the gold medal of that society. In 1892 the prince made a short journey in East Africa, and shortly afterwards visited Madagascar, proceeding thence to Tongking. From there he set out for Assam, and found the sources of the Irrawaddy, which secured the medal of the Geographical Society of Paris and the cross of the Legion of Honour. In 1897 he revisited Abyssinia, and political differences arising from this trip led to a duel with the comte de Turin, in which both combatants were wounded. While on a trip to Assam he died at Saigon on Aug. 9, 1901. ORLEANS, HENRIETTA, DUCHESS OF (1644-1670), third daughter of the English king, Charles I., and his queen, Henrietta Maria, was born during the Civil War at Exeter on June 16, 1644. A few days after her birth her mother left Eng land, and she lived at Exeter under the care of Lady Dalkeith (afterwards countess of Morton) until the surrender of the city to the parliamentarians, when she was taken to Oatlands in Surrey. In July 1646 she rejoined her mother in Paris, where her
girlhood was spent and where she was educated as a Roman Catholic. Henrietta was mentioned as a possible bride for Louis XIV., but she was betrothed to his only brother Philip. After the restoration of her brother Charles II., she returned to England with her mother, but a few months later she was again in Paris, where she was married to Philip, now duke of Orleans, on March 3o, 1661. The duchess was very popular at the court of Louis XIV., and was on good terms with the Grand Monarch, but she was soon estranged from her husband, and her conduct was very imprudent. In 1670, at the instigation of Louis, but without Philip's consent, she visited England and obtained the signature of Charles II.'s ministers to the treaty of Dover. Shortly after returning to France, Henrietta died at St. Cloud on June 3o, 1670, and it was asserted that she had been poisoned by order of her husband. She left two daughters, Marie Louise, wife of Charles II. of Spain, and Anne Marie, wife of Victor Amadeus II. of Savoy.
