The author has suggested that this text might be subtitled "Atoms and Tbeir Consequences" and he uses this theme to develop an introductory chemistry course which begins with the nature of atoms and emphasizes throughout, "the cause and effect relationship between the nature of atoms and the physical and chemical He states that properties of matter!' while attempting "to explain chemistry as thoroughly and as simply as I can," he feels confident that the student who has mastered this book should be well DE-

the number of electrons (paired and unpaired) and the vacancies in the orbitals avdahle for bonding, an exhaustive though possibly biased treatment of electronegativity, chapters on the atomic origin of oxides and fundamental interpretations of hydrogen compounds which are surveys of the structure and properties of compounds of oxygen or hydrogen with the other elements. Every attempt has been made to make the presentation simple and clear, and to help the student master the material. Examples and analogies are prevalent and effective. Exercises at the ends of chapters have been carefully worked out and indude sections such as Test Your Memory, Test Your Math, and Test Your Understanding. An especial effort to include modern theory, theory terminology, and topies or terms often covered a t more advanced levels has been made. Terms such as wave mechaics, molecular orbitals, hybridization, free energy, entropy, and enthalpy appear. In some instances the author does an excellent job of using these terms and ideas to explain or predict behavior--this is especially tme in areas of molecular structure. In other instances important terms or ideas are presented briefly and not mentioned again. Several inorganic chemists who examined this text felt that the concept of electronegativity as presented here has been extrapolated beyond its scope of

reliability. A physical chemist felt that the schematic diagrams far electrons and vacancies in atoms are unnecessary and misleading. To this reviewer the text, if intended for college classes, falls short on three counts: it fails to penetrate deeply enough into any topic to give the student a mature indication of how far chemical knowledge has advanced and of the real intellectual challenge involved in comprehending such knowledge in depth; it gives virtually no idea haw this knowledge is obtained and what the limitations on our knowledge really are; it fails to emphasize effectively the quantitative nature of chemistry. Even though this hook has been written with great oare and consideration for the students who will use it, and with much thoughtful study, careful selection of material and examples, and with obvious understanding of the subject matter, I cannot believe that a student who "masters" the material as presented in this text is ready for advanced college level chemistry courses.

Certainly one of the most accomplished writers in the field of hiochemistry today His book "Dynamic is Ernest Bald-. Aspects of Biochemistry," now in its fourth edition, is a highly regarded k t book, and his treatise. "An Introduction to Comparative Biochemistry," also in its fourth edition, is a widely accepted standard. His presentation is always lucid, and his style, marked by his engaging wit, is smooth and enjoyable. In "The Nature of Biochemistry," Professor Baldwin has set out to give an idea of what biochemistry is about to the student whose vague picture of biochemistry is the result of brief and misleading encounters with today's news media. A rudimentam knowledee of structural ornor the inclination to teach it. The story fallows essentially an evalutionmy approach, beginning with arguments supporting the oceanic origin of life, followed by the development of a d a p tive mechanisms necessitated by migration from the comfortable constant physical and chemical environment of the sea to the changeable climatic conditions an land. Here proteins are introduced as homeostatic factors in blood, and, from this point, the discussion proceeda a t the molecular level. Catabolic pathways of proteins, carbohydrates, and fats are p ~ sented in outline and their convergence at the citric acid cycle is emphasized. The next logical step-the harnessing of the energy from these processes-is then explained, and the cycle is completed by mentioning the utilization of this energy

Although the author states in his prologue that this small book is for reading and not study, and that it is not intended to be a supplementary treatise, it is recommended for those students who indicate an interest in biochemistry, not only as a brief preview of the nature of biochemistry, hut also as an example that not all scientific writing need be prosaic.

Chemical Applications of Infrared Spectroscopy

The continual appearance of diverse books on infrared spectroscopy shows the liveliness of this field. In a subject with so many ramifications there is certainly room for a variety of hooks and probably no single volume can adequately cover all aspects of the subject. The him of the volume under review is "to present basic concepts, measurements, and techniques of infrared spectroscopy rtnd to survey as completely as possible its chemical applications." Except for certain omissions, the last goal is well ful6lled. Whether the other aims are adequately realized will depend upon the interestsoffhereader. The first chapter is devoted to basic concepts, instrumentation and technique. One is immediately aware of a particularly strong point of the boak, namely, the abundance of specific examples, data, spectra, and graphs. The level of treatment is low-intermediate. The basic concepts are handled in a nonmathematical manner. There is a qualitative discussion with diagram of the modes of vibration but there is no discussion of symmetry properties or rotational 8pectra. Emphasis is on the factors which affect the vibrational modes in complex molecules. Thus, students desiring a firm grasp of theory will have to look elsewhere. The neophyte in practical work in infrared spectroscopy will need supplementary material. Under instrumentation and technique a large number of topics is discussed but at times the treatment is somewhat sketchy. For example, there are sections on microtechniques, spectra under high pressure, difference and derivative spectroscopy but there are few how-to-do-it directions. For instance. nothine is said about how ane pdishrs n rock salt wiudow. It should be menrimed hwwver that srlcqu~1ereferenws are ~ r for m both the bwinner snd the advanced worker. The hulk of the book is devoted to structure correlations in the near, medium, and far infrared regions. Individual chapters are devoted to the various classes of organic compounds, to high polymers, to specific applications to organic chemistry, and to biochemistry. A chapter on inorganic compounds emphasizes simple and complex ions. The spectra of an
