interesting physical phenomena. The research worker will find here over two hundred useful references to the original literature. Many unsettled questions are discussed and it is made plain that here is an important field for further intensive investigation. The present report may well serve as a catalyst for the production of a comprehensive monograph on the subject in which more complete discussions will be possible. J. H. MATHEWS
