The scope and intention of this volume need some explanation. It was begun with the idea of providing a text-book from which students, well grounded in the elementary branches of physics, might obtain some knowledge of the later developments; there is 'no doubt that such a book is needed urgently. But, in the course of writing, departures from the original scheme have been made. There are lengthy descriptions of theories which may be assumed to be familiar to such students, and there are discussions of controversial questions which may be thought undesirable in the early stages of study: it is improbable that a reader, who could gain much new information from the first chapter, could gain much benefit from the last. On the other hand, the book does not aspire to the dignity of a treatise designed to bring the results of the latest original research to the notice of those who have made a special study of the newer branches of physics: there is little that is not well-known to all professed students of the subject.

The extent of each monograph corresponds roughly to that of a chapter of the book. Accordingly, in order that there may be continuity between the book and its supplements, the monographs are called chapters and numbered consecutively with the chapters of the book. Chapters I — XIV are in the book; subsequent chapters are monographs. References from one part of the work to another are made by chapter and page numbers. Although the form of the book, and probably much of its authorship, will be changed, its purpose will remain unaltered. It is still intended, not for experts, but for students who, having taken the usual examination courses, wish to get into touch with research. It aims at giving them such knowledge of the chief regions in which research is active that they may proceed at once to the original memoirs; much more attention is therefore given to the clear exposition of the main ideas which inspire the research, than to detailed statements of the results that have been obtained from it. References to original literature are not given; for, if the book attains its object, the literature to which it is most important that the reader should turn is that which is not yet published.
