scale of these preparations varies with the synthesis, generally being in the range of 0.5-2 moles of compound. However, the preparation of cholestanyl methyl ether is on the millimale scale.

Same examples of the many different types of reactions are osonalysis, electro- chemical reductions, carbene synthesis, Grignard and organorn&allic-type reac- tions, etc. The most unusual compound for which a synthesis was described is tetrameth,vlammani~~~n 1,1,2,3,3,-pentacy- anopropenide. This substance is a strong acid of pKa -8.5, a value that compares with strong mineral acids.

This volume contains the same careful directions and precautions that have slwa,vs marked this scries. One new feature, point 4 of bho organization of a synthesis, has heen added. This is titled Merits of the Prcpnration, and consists of s. brief evaluation of thc synthesis, its generality and t,he usefulness of the compound. This feature is s valuable addition to the volume.

This textbook is similar in its approach to the author's "Principles of Chemistry" published in 1958 (reviewed in J. CHEM. Eooc., 37, 107 119601). Nineteen of the twenty-five chapters have the same titles and cover essentially the same meterial as the earlier text. The prin- cipal change in the new hook is the in- clusion of chapters entitled The Oxygen Family, The Halogens, The Nitrogen Family, The Representative Metals, and The Transitional Metals, whereas the former hook had only two chapters devoted specifically to the chemistry of the elements-those on Oxygen and Hydrogen. Some descriptive chemistry also is interwoven throughout the other chapters, but the emphasis continues to be on the fundamental concepts of the composition and behavior of matter. The other new chapter is called Chemical Bonding and Architecture. The rela- tionship of structure to chemical and physical properties is stressed continually by using simple compounds as prototypes.

The format of the hook is attractive, with clear type and exceptionally large page numbers. Location of tapica is facilitated by listing the chapter title under the left hand page number and the section number and topic under the right. The hook has several diagrams and drawings, but no photographs.

Many of the chapters hegin with en introductory section entitled A Per- spective, and end with A Summary. Each chapter is followed by a set of thaught-provoking questions and prob- lems; answers to those which are numeri-

c d are given in the hack of the hook. Unfortunately, the author nowhere makes any mention of significant figures and is not consistent about them in the answers to hi8 problems. He also is careless about the inclusion of dimensions and units in his otherwise good examples.

The appendix contains nine tables of useful information and data. The L i t of suggested readings supplied in t,he 1958 text has been dmpped from the newer book. Probably the students do not miss this, hut their professors might.

Theoretical sections are up to date and used as an admirable means to demonstrate the productivity of logical reasoning based on valid principles. While not technically incorrect, one wonders why the author deviates from the usual usage in reference to the hy- drated proton. He seems to prefer to consider i t s protonated water moleculr, calls it the oxonium ion, and writrs i t OH8+.

This book will he quite satisfactory as s. text in introductory courses where the application of common sense reasoning is stmssed and emphasis is placed on major chemicnl principles rather than on the chemical propertips nf t,he clrments and their compounds.

Elements of Thermodynamics and Heat Transfer

Edward F. Ot t r l , University of Wis- consin, Madison, and Robert L. Young, University oi Tennessee, Knoxville. 2nd ed. McGran.-Hill Book Co., Inc., 1962 xir + $A8 pp. Figs. and tables. 16 X 23.5 cm. $8.95.

This hook, x revision of an earlier work, runs counter to the usual current presentations in bhat i t conlhines thermo- dyn~mics and hest transfer. The treat- ment of thermodynmnics follows the Carnot development and therefore relies heavily on methods of analysis involving the heat engine. The bmic thermody- namical l a m are lucidly set forth by Professors Ohert and Young. H o ~ e v e r , phvsical equilibrium in multicomponcnt systems and chemical equilihrinm receive a mir~imum of attention.

The Ireat t r a d e r section is too brief for n. thorough understanding of the material. In vie,,. of the iact that s, more extensive, separate course is usunllp given, the final tno chapters on heat transfer seem to he an unnecesssry adrli- bion to the thern~odynamics section.

I t wouhl seecn~ that the exposition presented ~vauhl he found sstisfact,ory as an introductar>- t rs t in thermodynamics for mcchnnirnl imgineers and as supplc- menbsry wading fol. othera.
