This well-produced book comes to us from Norwegian authors, whose English is very accurate and clear. Very few typographical errors are apparent, and the layout is such as to invite the reader to tackle the contents. This is a distinct plus for anyone such as your reviewer, who years ago had to try and digest the available texts of, amongst others, Prigogine and de Groot. These earlier masters were not easy reading~they could not really be blamed, since the subject is complicated. The joys of linear transformations and different frames of reference are a taste which takes some acquiring.
The authors of this book have tried to keep things simple, with the minimum of mathematical complexities. Uni-directional phenomena related to experimental measurements form the subject matter of this book. It is aimed at seniorlevel students, and there are examples at the end of most chapters to give the reader a chance to use the equations (answers are provided at the end of the book).
The book is divided into two nearly equal parts, on the theory and on applications. Part 1 consists of seven chapters. The first three, the Introduction, on entropy production, and on the flux equations, are short, and perhaps a little overcondensed. They would benefit from expansion by the teacher in any course application of the book. It is not easy to be precise and rigorous in this field. Years ago Coleman and Truesdell showed the risks of a cavalier approach to Onsager's reciprocity relations.
The next three chapters are more substantial, and deal with transport in concentration cells, ion-exchange mem-
