The Readings in European History, a manual now in preparation, and designed to accompany this volume, will contain comprehensive bibliographies for each chapter and a selection of illustrative material, which it is hoped will enable the teacher and pupil to broaden and vivify their knowledge. In the present volume I have given only a few titles at the end of some of the chapters, and in the footnotes I mention, for collateral reading, under the heading Reference, chapters in the best available books, to which the student may be sent for additional detail. Almost all the books referred to might properly find a place in every high-school library. J. H. R.
