throughout all phases of the text does make for interestine and informative resdine:

found in most general chemistry textbooks, since industrial processes are described rather in detail wherever it is possible throughout the book. In fact; the instructor using the hook will have to pick and choose some of the material and perticulmly only portions of the exercises since over a thousand are available at the end of the chapters. Teachers of beginning college chemistry who are concerned with the problems of accepting average students into a program which is destined to serve as a science requirement and in preparation for more chemistry should find this book very helpful. The explanations me clear and concise, and the illustrations are particularly well done. The separation of the problem examples from the text by a colored line, emphasizes the importance of the quantitative nature of chemistry and can be used extensively, or left out by choice. The inchion of the features mentioned above, plus the absence of typographical errors and misstatements makes it easier for the student and the teacher to select an adequsteprogramfor general chemistry.

presentation. There has been considerable reorganiaation in the presentation of material. C h a p ters have been shifted around, and some topics have been placed in new and s e p arate chaoters. The text now consists

in the earlier text. Major changes are found in the following chapters: Density and Specific Gravity (material now in a separate chapter), Spectrophotometry (formerly, Colorimetry), Theory and Praetice of Titrimetry Based on the Formation of a Precipitate, Theory and Practice of Titrimetry Based on the Formation of a Slightly Dissociated Compound (material on precipitates and slightly dissociated compounds was previously found in a single chapter). The remaining chapters include revisions of various degrees; such revisions including the deletion of some topics (for example, titrstions with bromate and indirect analysis), plus the inclusion of new topics (for example, single-pan balances and relative standard deviation).

As Professor Kenner states in his Preface to "Analytical Determinations and Separations," the chemistry curriculum is in a. state of flux. In addition, he is absolutelv correct in that the ouantitative

ate chemistry courses. Here yesterday, gone today, back in another spot tomorrow. No one can say with certainty what the sndytical course will he or where it will settle down in the "newer" chemistry curricula being developed at this time. This uncertainty is one of the causes for the somewhat unsatisfactory nature of the books (or book) being reviewed. In discussions with various people, one acquires the feeling that the economio difficulties of the publishing industry have led many publishers to try to make sure that every text-hook is suitable for all possible markets. Professor Kenner correctly indicates that there is a need for a lower level quantitative analysis book than some of those presently available. Hawever, a. book of this sort naturally would have a limited market. Therefore, somewhere along the l i ~Professor , Kenner has been prevailed upon to add sections an several of the more sophisticated analytical techniques and we are back to ground zero again.

Factual information about products and yields from reactions is certainly important t o orgrtnic chemists, and this b m k contains a great deal of suoh information. Approximately ,5000 journal articles, reviews, and books that have appeared

mostly in the period 1940-68 are cited. Creation of a. particular class of hydrocarbon or functional group from other hydrocarbons or functional groups is the main concern of the work. Headings under which the material is organized are: alkanes, cyeloalkrtnes, arenes, alkenes, cyeloalkenes, dimes, alkynes, alcohols, phenols, ethers, halides, amines, scetals rtnd ketrtls, aldehydes, ketones, quinones and related substances, carboxylic acids, carboxylic esters, acyl halides, carboxylic acid anhydrides, ketenes and ketene dimers, carboxylic acid ilmides and imides, nitrilks, nitro compounds. The presentation is concise, rather informel, and generally pleasant to read. General reactions are illustrated with a variety of specific examples. Structn~al formulas me used liberally. Literature references and percentage yields are supplied faithfully. Experimental conditions rtnd mechanisms for many reactions are indicated. There are numerous helpful comments about the advantages and disadvantages of alternative methods. The title of the book suggests that syntheses of peptides, nucleotides, and other complex natural products might be included, but such is not the case. The transformations presented involve no more than afew steps and complex syntheses are not discussed. Biochemists will not find much of interest. Applications of borohydrides, photochemistry, and industrial organic chemistry are covered reasonably well. The book is recommended ss a great convenience in dealing with a substantial portion of the literature, and as a source of general information about basic organic chemistry. The author and subject indexes are quite complete. The number of proofreading oversights is not notable. The creftsmanship of the publisher is good.

There are a number of advertised features of this laboratory text which are intriguing. The features are there and some of them quite good. Unfortunately, however, the book is not well written. Although i t may well provide some interesting and useful ideas for an instructor, the texts by Daniek, et al., and Shoemaker and Garland make better reference books for students and have superior experiments of t,he chemical-physics variety. This text begins with a. short description of how to write a laboratory report, followed by a sample "good student laboratory report!'
