Books

Some of the information on the principles underlying the concept of pH is incomplete or unclear. As an ex­ample, the statement is made in chap­ter 1 that "the observed potential from the glass electrode varies in a known manner, the Nernst equation", which is intended to mean "the ob­served potential of the glass electrode varies in a known manner, which is given by the Nernst equation". Poor syntax may be responsible for some of the incorrect material, but the fact remains tha t any standard textbook of either general chemistry or quanti­tative analysis contains much more in­formation describing the basis on which pH principles were founded. If the information itself was not deemed necessary for inclusion in this book, it should at least have been cited as a further source in the bibliography.

The author's greater familiarity with the routine aspects of pH mea­surements appears to have unfairly bi­ased him against the application of this method in analytical techniques involving difficult applications. Thus, the book seems to be more useful in everyday operation of pH meters in­volving simple systems, but totally in­adequate in dealing with those of greater complexity, even though the publisher's description of the book in­cludes "the use of proper technique in difficult applications".

The editing of the book is fair, al­though there are numerous typo­graphical errors. Many instances of poor sentence construction (e.g., " the temperature coefficient of the glass electrode is normally designed to match the calomel reference electrode temperature coefficient to the isopo-tential point, for either electrode is approximately the same") are noted throughout.

As the preface states, "This book is an a t tempt to give an account of the development and applications of the modern mass spectrometer." It is a carefully and well-produced member of a series intended for students at the beginning undergraduate level. In a total of six chapters and 147 pages, the principles of mass spectrometry and its application to chemistry, biochem­istry, geology, medicine, and space are dealt with. One might well expect
