The third edition is devoted to the task of describing and classifying the various families of sedimentary rocks and to an understanding of their textures and structures. Beyond this description there is a brief statement on origin insofar as it can be deduced from the relevant field and laboratory observations no attempt is made to explore the physics or chemistry of the formative processes. In general the emphasis has moved away from thin-section analysis of sedimentary rocks (though this remains an important topic) to a closer look at the outcrop and the utilization of both sedimentary structures and the vertical profile or sequence in sedimentary analysis.

The purpose of the third edition is to mirror the present transition within industrial psychology in. the same fashion as the 1956 edition mirrored the contemporary change within the field at that time. A second objective of the present revision is to make the general level of the presentation somewhat more sophisticated than has been the case with earlier editions. Experience with students over the past few years has led to the conclusion that todays college student is a more knowledgeable and better trained person than the student of the past. The classical areas of industrial psychology are presented in the early chapters: Prediction techniques (Chapter 2 and 3), industrial tests (Chapter 4), and other selection techniques (Chapter 5) are each examined in turn. In these chapters the attempt is made to present the conceptual and theoretical models and problems critical to a basic understanding of the topic. Chapter 6 is a detailed discussion of the criterion problem. Chapters 7, 8, and 9 discuss performance appraisal (a logical continuator of the criterion chapter), training, and attitude measurement. With this last chapter the transition begins to take place into the more social aspects of industrial psychology such as the Hawthorne studies (Chapter 10), motivation (Chapter 11), job satisfaction (Chapter 12), morale (Chapter 13), and leadership and supervision (Chapter 14). Throughout all these chapters the emphasis is one of examining the models or theories which seem to be developing in each of these areas.
