Recent The outline of the book follows the well developed outline used in other editions and achieves a clear and integrated ammation of our knowledge of nutrition to the moment. The clearness and logical development are as evident as in all writing by these authors. However, although the book is addressed to the elementary students, the writing is fairly difficult and uses many inflected words common to scientific papers. Occasionally the anthors drop in a chabty phrase, but for the most part the familiar and easy style which is now used in many elementmy science hooks and which elementary students find em,, to read, is missing. The section (Chapter 2) which attempts to describe embohydrates, proteins, and lipids in general terms without the use of a.rhemiral background appears particuldv difficult. This is' an admittedlq hard assignment for any writer, hut the use of chemical names appears to the reviewer to add confusion rather than clarity far the sttident. The suggested reading lists st the end of each chapter have been expanded to include a few new references. These have always been helpful for the tearher and the outstanding student and their continued use is excellent. The make-up of the book is very good, with fine paper and clear print easily readable. The number of illnstrations has not heen expanded. This is regrettable dnce many interesting ones are available in this field and they add a great deal of interest far the students. Although the hook is written as a textbook far courses in nutrition, it will be useful to students in general chemistry as supplementary reading and as an authoritstive reference book for speoid projects. High school studenta rw well as college students should be able to use it. A few insignificant details which the reviewer questions me the definition of the term "lipaid" on p. 21 and the inclusion of hemicellulose as a widely distributed class of carbohydrates without the inelusion of the better known nectic substances. But by and large it iidiffioult to find anything to criticize in this owellent hook. LILLTAN HOAGLAND MEYER WEBT..N M , C " ~ , W UNI,.ERBII~ KAI.AM*EOO. MIORIDAN

THEauthors have organhed the material usually found in a college chemistry text into chapters containing about 20 naees each. which contain in addition to
intervals discuss phases of chemist,ry (Continuedon page A28) JOURNAL OF CHEMICAL EDUCATION
(called "per~pectives" by the authors) not usually found as chapter subjects. Perspective 1: "How Discoveries are Made" discusses inductive and deductive reasoning and the scientific method of investigation. The role that chance, intuition, and design have played in important discoveries is descrihcd and empha~isis placed on the receptive mind when observations are made as the key to new advances. Perspective 2: "The Development of Chemistry as a Science" is n short, wellorganized summary of the important milestones in the history of chemistry and is developed chronologically. Perspective 3: "The Chemical Nature of our World" which immediately precedes the inorganic descriptive portion deals with the theories concerning the origin of the world and the universe, distribution of the elements, composition of the earth's crust, the atmosphere, the hydrosphere, and the biosphere. The book concludes with five chapters of organic chemistry, 78 pages in which the most generally applicable portions of the subject me covered in a logical and well illustrated form. The choice of material covered in this book is excellent; however, this reviewer finds the order in which the subject matter is presented requires that should the instructor wish to use a structursl approach it becomes necessary to reestablish the order in which the chapters are taken up. The early chapters cover very well the problem of the molecular and atomic structure of matter, but the properties of these particles which are derived from atomic structure are not discussed until Chapters 16 and 17. Following the same thinking as ahove, the organic chemistry is placed st the very end of the book, far removed from any discussion of bonding. Some references are made to early chapters where the subject of bonding is taken up, but its lochon seems to separate the organic portion from general theoretical hackground. Those instru~tomwho wish to use the more conventional approach will find this hook very helpful. Its clear, concise explanations, with plenty of illustrations and the absence of typographical errors uill make it easy for the student to understand and the instructor t o teach. JAMES F. CORWIN
