This Series is primarily designed to aid the University Extension Movement throughout Great Britain and America, and to supply the need, so -widely felt by students, of Text-books for study and reference, in connection with the authorised Courses of Lectures.
Volumes dealing with separate departments of Literature, Science, Art, and History have been assigned to representative literary men, to University Professors, or to Extension Lecturers connected with Oxford, Cambridge, London, or the Universities of Scotland and Ireland.
The Manuals are not intended for purposes of Elementary Education, but for students who have made some advance in the subject dealt with The statement of details is meant to illustrate the working of general laws, and the development of principles, while, the historical evolution of the subject dealt with is kept in view, along with its philosophical significance.
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 teach those resident in the larger centres of population, while all over the country there arc thoughtful persons who desire the same kind of teaching. 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.
