potheses in science. It is typical of the author's efforts to blend in pertinent ideas from scienee-related fields. Chapters 8 and 9 include a study of heat and its nature and a quantitative treatment of the kinetic molecular theory. The early developments in electrochemistry are given in Chapter 10 and a study of cell reactions and the electrolytic processes are given in Chapter 11. The relationship of the free energy change and maximum work for an electrical cell is introduced. Chapter 12 considers eoncentnttion and some of the ways in which concentrations are expressed. The alkaline-earth metal family is discussed in Chapter 13. Included are important appropriate theoretical topics such as the Born-Haber cycle, the lattice energies, and hydration energies. Chapter 14 is a well-written treatment of equilibrium with consideration of certain thermodynamic ~rinciples on a noncalculus level: the free-energy equilibrium constant relationship, the heat content, and entropy relationship. The chapter concludes with a, treatment, of some representative equilibria. involv~ng both physical and chemical processes. Rates of reactions is covered in Chapter 15. In Chapters 16 and 17 the author treats acid-base theory, and heavy emphasis is placed on illustrating the applications and principles of equilibrium and mte behavior. A brief discussion of the periodio table and its utilization follows in Chapter 18. Chapter 19 is concerned with the halogen family, and additional important theoretical concepts are included with emphasis on geometry and structure. I n this chapter are found excellent treatments of the halogen acids and other binary halides. Beginning with Chapter 20, which is concerned with the early developments in the study of spectra, the author discusses the development of man's understanding of the structure of atoms and molecules, drawing upon both physics and chemistry. Chapters 22, 23, 24, 25, 26, 28, and 29 inolude: the structure of atoms, electrons, and protons, atomic structure, X-rays, radioactivity and neutrons, nuclear reactions, electronic distribution, nature of molecules, the fine structure of molecules, and and waves. This material, which is one-13th of the text, provides the student with considerably more hackground coverage of atomic and molecular theory than found in most textbooks. The inclusion of chapters on bonding so late in the textbook might be considered a serious objection by some, but most of the descriptive chemistry still follows in later chapters. The remnining chapters (21, 27, 30, 31, 32, 33, 34, 35, and 36) include the rare gases, hydrogen, the oxygen, nitrogen, carbon, and boron families as well as three chapters covering the bransition elements. These chapters of so-called "descriptive chemistry" include modern concepts and theories and use illustrations of the latest research findings. The last three chapters on the transition metals are exceptionally illustrative of the author's ability to correlate the chemical principles and modern theories with the properties and reactions of the elements and their compounds. Topics included are: coordination compounds, isomerism in complex ions, valence bond theory,

magnetic susceptibility and (briefly) mcdern a ~ ~ r o s c h eto a the coordinate bond (eryst'ai field, ligsnd field, and molecular orbital theory). The book is organized and written not only to teach the beginner hut also to challenge the advanced student. The second half of the hook, heainnina with the development of aton& and moiecular theory and ending with well-written c h a p tern dealing with selected families of elements, is the most impregsive part of the hook. Equally impressive in the reviewer's opinion is the fact that the text would he suitable for the non-chemistry major as well as the chemistry major. "Chemistry: An Introduction to Matter and Energy," departs from the usual pattern found in most chemistry texts. It is exceptionally will written and should be examined carefully by d l teachers of beginning chemistry.

Rather than being a new text on analytical chemistry, this book is simply an ahbreviated version of the earlier "Fundamentals of Analytical Chemistry," by the same authors. Absolutely no novel material is presented in the newer book; instead, 21 of the 31 chapters of the earlier text have been gathered together to create a volume having 527 rather than 786 pages. The cost per page has, incidentally, increased. Since the material contained in this volume is also covered in the earlier book, my comments (Anal. Chen., 35(8), 50.4 P. CALVINMAYBURY [1963]) regarding that version are still applicable. Presumably, the justification University of South Flmida for this condensed version of the older text Tampa is that the present book will serve the need for an introductory text, perhaps in a onesemester course.
