As STATED in the preface, this addition to Methuen's Monographs on Chemical Subjects is designed to stimulate intwest, and research in the defect solid state, particularly as applied t,o chemistry. With this objective in mind, the author presents a well oreanized and interestine account of aonoents basic to an

I t is loaded with pertinent examples, yet is unhardened by the details necessat? for one working in the field. The chapter on Nuclear React.01.streats the essential problems in comprehensive fashion, but it falls far short of presenting the present status of successful achievements in the field. This will
