It has seemed to me impossible to deal with the long period covered by this volume as briefly as the scheme of the series required without leaving out a great many events and concentrating attention chiefly upon a few central facts and a few important personages. I think that the main results of the development may thus be seen, though there is much which is here omitted that would have been included had the book been written on other lines. Some pages find place here which originally appeared in The Guardian and The Treasury, and a few lines which once formed part of an article in.
