IJ. l:. I.

knowingly a p p l y the theory of limit design. An appendix to the book contains several problems with answers. As a handbook of design, in the sense that an ordinary strength of materials book contains the solution for many structural problems, the Theory of Limit Design is not very useful. But as a statement of the principles of a new approach to structural engineering design, it is an interesting and stimulating book.

E. W. HAMMER, JR. BOOK NOTES PRINCIPLES OF STRUCTURAL GEOLOGY, by C. M. Nevin. Fourth ed., 410 pages, 15 × 24 cm., illustrations. New York, John Wiley & Sons, Inc., 1949. Price, $6.00. In revising this standard text on structural geology, the a u t h o r has eliminated specific references to source material, as he found that they were little used by the students for whom the book was written. However, material for further study is indicated in the form of selected references at the end of each chapter. A new section of laboratory exercises has been added with both sample and practice problems. This continues to remain a useful introduction to the deformations of the earth presenting the various ideas and viewpoints. THE NATURE OF PATENTABLE INVENTION, ITS ATTRIBUTES AND DEFINITIONS, by John E. R. Hayes. Second ed., 187 pages, 15 X 24 cm. Cambridge, Mass., Addison-Wesley Press, Inc., 1948. Price, $5.00. Rearranged and in part rewritten, this study on invention is made available in a second edition. The discussion of the attributes of invention as a means to a definition of invention is of interest. Many additional cases have been cited in support of the author's thesis. ROUTE SURVEYING, by George W. Pickels and Carroll C. Wiley. Third ed., 434 pages, 11 X 17 cm., illustrations, tables. New York, John Wiley & Sons, Inc., 1949. Price, $4.75. This practical book on route surveying, which may serve either as a textbook or a reference book, has been extensively revised to increase its value. Primary emphasis is on railroad surveys, but highway surveys are also treated, with a brief mention of canal and drainage, pipe-line and transmission-line surveys. Of particular interest to railroad engineers will be the full revision of chapter six on stringlining railroad curves, which .presents the basic principles involved as well as detailing the mechanical procedures. Although logarithmic tables have been omitted as of little value, the five-place tables of the natural trigonometric functions have been replaced with seven-place tables and other new tables added. INTRODUCTION TO PHYSICS, by Harley Howe. Second ed., 599 pages, 15 X 23 cm.,illustrations. New York, McGraw-Hill Book Co., Inc., 1948. Price, $4.50. An elementary college textbook in physics which requires only elementary algebra and plane geometry. I t attempts to be "practical" by referring frequently to the everyday experience of the reader. Chapter summaries and numerous problems are among the features of the book. THE MATHEMATICAL BASIS OF THE ARTS, by Joseph Schillinger. 696 pages, 17 X 24 cm., illustrations, tables. New York, Philosophical Library, 1948. Price, $12.00. Over a period of twenty-five years Mr. Schillinger did much research on principles of mathematical logic underlying varying forms of a r t structures. This volume presents his "scientific theory of the a r t s " in its three main branches: the semantics of esthetic expression, the theory of regularity and coordination, and the technology of a r t production. He foresees eventually the use of the scientific method in a r t production and the possibility of having music or painting or poetry designed and executed just as engines or bridges are.
