_The remarkable success which has attended University Extension in
Britain has been partly due to the combination of scientific treatment
with popularity, and to the union of simplicity with thoroughness.
This movement, however, can only reach those resident in the larger
centres of population, while all over the country there are thoughtful
persons who desire the same kind of teaching. It is for them also that
this Series is designed. Its aim is to supply the general reader with
the same kind of teaching as is given in the Lectures, and to reflect
the spirit which has characterised the movement, viz., the combination
of principles with facts, and of methods with results._

_The Manuals are also intended to be contributions to the Literature
of the Subjects with which they respectively deal, quite apart from
University Extension; and some of them will be found to meet a general
rather than a special want._

_They will be issued simultaneously in England and America. Volumes
dealing with separate sections of Literature, Science, Philosophy,
History, and Art have been assigned to representative literary men,
to University Professors, or to Extension Lecturers connected with
Oxford, Cambridge, London, and the Universities of Scotland and
Ireland._

_A list of the works in this Series will be found at the end of the
volume._
