CHARLES ANNE LAISANT (1841– ), French politician, was born at Nantes on the 1st of November 1841, and was educated at the Ecole Polytechnique as a military engineer. He defended the fort of Issy at the siege of Paris, and served in Corsica and in Algeria in 1873. In 1876 he resigned his commission to enter the Chamber as deputy for Nantes in the republican interest, and in 1879 he became director of the Petit Parisien. For alleged libel on General Courtot de Cissey in this paper he was heavily fined. In the Chamber he spoke chiefly on army questions; and was chairman of a commission appointed to consider army legislation, resigning in 1887 on the refusal of the Chamber to sanction the abolition of exemptions of any kind. He then became an adherent of the revisionist policy of General Boulanger and a member of the League of Patriots. He was elected Boulangist deputy for the 18th Parisian arrondissement in 1889. He did not seek re-election in 1893, but devoted himself thenceforward to mathematics, helping to make known in France the theories of Giusto Bellavitis. He was attached to the staff of the Ecole Polytechnique, and in 1903-1904 was president of the French Association for the Advancement of Science. In addition to his political pamphlets Pourquoi et comment je suis Boulangiste (1887) and L'Anarchie bourgeoise (1887), he published mathematical works, among them Introduction a l'etude des quarternions (1881) and Theorie et applications des equipollences (1887). LAI-YANG, a city in the Chinese province of Shan-tung, in 37° N., 120 55' E., about the middle of the eastern peninsula, on the highway running south from Chi-fu to Kin-Kia or Tingtsu harbour. It is surrounded by well-kept walls of great antiquity, and its main streets are spanned by large pailous or monumental arches, some dating from the time of the emperor Tai-ting-ti of the Yuan dynasty (1324). There are extensive suburbs both to the north and south, and the total population is estimated at 50,000. The so-called Ailanthus silk produced by Saturnia cynthia is woven at Lai-yang into a strong fabric; and the manufacture of the peculiar kind of wax obtained from the la-shu or wax-tree insect is largely carried on in the vicinity.
