Discover the Long Lost Ten Tribes of Israel_ (1816), in which he

BOUE, AMI (1794-1881), Austrian geologist, was born at Hamburg on the
16th of March 1794, and received his early education there and in Geneva
and Paris. Proceeding to Edinburgh to study medicine at the university,
he came under the influence of Robert Jameson, whose teachings in
geology and mineralogy inspired his future career. Boue was thus led to
make geological expeditions to various parts of Scotland and the
Hebrides, and after taking his degree of M.D. in 1817 he settled for
some years in Paris. In 1820 he issued his _Essai geologique sur
l'Ecosse_, in which the eruptive rocks in particular were carefully
described. He travelled much in Germany, Austria and southern Europe,
studying various geological formations, and becoming one of the pioneers
in geological research; he was one of the founders of the Societe
Geologique de France in 1830, and was its president in 1835. In 1841 he
settled in Vienna, and became naturalized as an Austrian. He died on the
21st of November 1881. To the Imperial Academy of Sciences at Vienna he
communicated important papers on the geology of the Balkan States
(1859-1870), and he also published _Memoires geologiques et
paleontologiques_ (Paris, 1832) and _La Turquie d'Europe; observations
sur la geographie, la geologie, l'histoire naturelle, &c._ (Paris,
1840).

BOUFFLERS, LOUIS FRANCOIS, DUC DE, comte de Cagny (1644-1711), marshal

dragoons. In the conquest of Lorraine (1670) he served under Marshal de
Crequi. In Holland he served under Turenne, frequently distinguishing
himself by his skill and bravery; and when Turenne was killed by a
cannon-shot in 1675 he commanded the rear-guard during the retreat of
the French army. He was already a brigadier, and in 1677 he became
