Another general chemistry text for average students has been added to the rapidly growing list. I n designing this text, the authors have attempted to give materid suited for both the average and the more inquisitive student. Some changes have been made, of which the most noticeable is the grouping of the descriptive chemistry under the headings of Monatomic Anions, Monatomic Cations, and Oxyanians. The hook assnrne.3 that the students have had a high school chemistry course, and apparently, that this background has given the student a wealth of understanding in terminology, alt,hongh little is presumed in the area of principles. Each page in the book is divided into two columns. One mlumn contains the text, while the other contains figures, tahles, occasional supplementary material for the better student, or is left blank. The type wed is unfortunately small. The beginning chapters on Elementary Principles, Atomic Structure, and Periodic Properties touch superficially upon many important principles. Electronic s L m e ture is introduced via five columns of historical development leading to quantum mechanics (Sohredinger's equation is then "derived" in the column for the more inquisitive student). The n quant,um

number is properly introduced as representing the main energy level, but immediately following this, the electron d i e tribution in the calcium atom is pictured as a. series of four equally spaced rings resembling rather diffuse Bohr orbits. Next, s-, p-, and d-orbital shapes are given without regard to t,he principle quantum number. Following the chapter on Periodicity are solid, but fairly standard treatments of types of bonding, and ions and molecules. Staichiometry and gas problem are next treated in much more detail than usually encountered in current texts. The a p proaeh is heavily weighted toward the mechanics of obtaining numeried solutions to the problems. Chapters on solids, liquids, and solutions very rapidly introduce many topics prior to the kinetics (using some simple calculus), equilibria, electrochemistry, and thermodynamics that precede the descriptive 1270 of the text. The final third of the text treats metals, complexes, nuclear chemistry, geochemistry, organic chemistry, biochemistry, and colloids. Some modifications in the grouping of subject matter and the idea of two levels of presentation are certainly to he commended. While porists may object to such matters as having an intermolecular potential diagram, labeled with farce and energy concurrently, or the incorrect ordering of the energies of the free ion versus the d ~ r h i t a lcomplexes, the greatest problem wit,h this text is that thestndent is very likely to he frustrated in any attempts a t gaining an underst,anding of the

Although the text is difficult in this regard, the advanced topics (e.g., the justification Brz of the mathematical form of the Ha kinetic equation, or the entropy introduced as "q,*,/T--a state of function") have been treated in only a superficial manner. The approach that has been used has allowed the authors to introduce a vast array of topics, and in a few cases, to p r o vide two levels of presentation.

"Chemistry in the Laboratory" is a laboratory manual for first-year wllege chemistry. Part A consists of 24 eaperiments which are cross-referenced to the two textbooks written by Professor Gregg, "Principles of Chemistry" (second edition, 1963) and "College Chemistry" (second edition, 1965). I t is assumed that the experiments will sometimes precede a detailed lecture discussion of the topic in question. The stndent is told that "this sort of sequence is historically wrrect, and is not a t all illogical." The manual could very easily he used with classeij using any text. Each experiment includes a brief hut adequate discussion section which the student will presumably read before he performs theexperiment,. Most of the experiments in Part A involve measurements of mass, volume, or temperature. Weighing with a preckioll of 5 mg is expected. For this, two-dial t,orsion balances are suggested. The pages of the manual are provided with tear-out perforations. Space is provided for the required calculatiom and for answering the supplementary rquestions and problems which are provided with each experiment. I t is recommended, however, that a notebook he used as a depository of data. I n Notes to the Student the authors state that the purpose of the laboratory 15 "to experience a t first hand the types of experiments and manipulations performed by chemists." The purpose is not to verify the facts and concepts presented in the textbook. Part A, in addition to many conventional topics, includes experiment? in which the student prepares basic lead chromate, basic lead acetate, potassillm
