onport for five years, he went to the War Office in
1870 to assist in the preparation of (Lord) Cardwell's measures of army
reform. He was appointed professor of military administration at the
Staff College in 1871. Early in 1873 he joined Sir Garnet Wolseley at
the Gold Coast, where he took charge of the transport, and the success
of the Ashanti expedition was in no small degree due to his exertions.
He was promoted brevet-colonel and awarded the C.B. In 1875 he
accompanied Wolseley to Natal (C.M.G.). On his return home he was
appointed military secretary to Lord Lytton, governor-general of India,
and in 1877 private secretary (K.C.S.I.). In 1879 he joined Wolseley as
chief of the staff and brigadier-general in S.E. Africa, but, on the
murder of Cavagnari at Kabul, returned to India. In 1880 he succeeded
Wolseley in S.E. Africa as high commissioner and general commanding, and
conducted the operations against the rebel Boers. He was defeated at
Laing's Nek and at the Ingogo river, and killed at Majuba Hill on the
27th of February 1881. He had a very high reputation not only for a
theoretical knowledge of military affairs, but also as a practical
soldier.

COLLIER, ARTHUR (1680-1732), English philosopher, was born at the
rectory of Steeple Langford, Wiltshire, on the 12th of October 1680. He
entered at Pembroke College, Oxford, in July 1697, but in October 1698
he and his brother William became members of Balliol. His father having
died in 1697, it was arranged that the family living of Langford Magna
should be given to Arthur as soon as he was old enough. He was presented
to the benefice in 1704, and held it till his death. His sermons show no
traces of his bold theological speculations, and he seems to have been
faithful in the discharge of his duty. He was often in pecuniary
difficulties, from which at last he was obliged to free himself by
selling the reversion of Langford rectory to Corpus Christi College,
Oxford. His philosophical opinions grew out of a diligent study of
Descartes and Malebranche. John Norris of Bemerton also strongly
influenced him by his _Essay on the Ideal World_ (1701-1704). It is
remarkable that Collier makes no reference to Locke, and shows no sign
of having any knowledge of his works. As early as 1703 he seems to have
become convinced of the non-existence of an external world. In 1712 he
