bearing the title _The Adventures of Captain Bonneville, U.S.A., in the
Rocky Mountains and the Far West._ Bonneville became a major in 1845,
and was breveted lieutenant-colonel for gallantry in the battles of
Contreras and Churubusco during the Mexican War. He became a colonel in
1855, commanded the Gila river expedition against the Apaches in 1857,
and from 1858 to 1861 commanded the department of New Mexico. He was

and commandant of barracks at St Louis, Missouri, receiving the brevet
rank of brigadier-general in 1865. He died at Fort Smith, Arkansas, on
the 12th of June 1878. The extinct glacial lake which once covered what
is now north-western Utah has been named in his honour.

BONNEY, THOMAS GEORGE (1833- ), English geologist, eldest son of the
Rev. Thomas Bonney, master of the grammar school at Rugeley, was born in
that town on the 27th of July 1833. Educated at Uppingham and St John's
College, Cambridge, he graduated as 12th wrangler in 1856, and was
ordained in the following year. From 1856 to 1861 he was mathematical
master at Westminster school, and geology was pursued by him only as a
recreation, mainly in Alpine regions. In 1868 he was appointed tutor at
St John's College and lecturer in geology. His attention was specially
directed to the study of the igneous and metamorphic rocks in Alpine
regions and in various parts of England, in the Lizard, at Salcombe, in
Charnwood Forest, in Wales and the Scottish Highlands. In 1877 he was
chosen professor of geology in University College, London. He became
secretary and afterwards president of the Geological Society
(1884-1886), secretary of the British Association (1881-1885), president
of the Mineralogical Society and of the Alpine Club. He was also in 1887
appointed honorary canon of Manchester. His purely scientific works are:
_Cambridgeshire Geology_ (1875); _The Story of our Planet_ (1893);
_Charles Lyell and Modern Geology_ (1895); _Ice Work, Past and Present_
(1896); _Volcanoes_ (1899). In addition to many papers published in the
_Quarterly Journal of the Geological Society_ and _Geological Magazine_,
he wrote several popular works on Alpine Regions, on English and Welsh
scenery, as well as on theological subjects.
