Of the fifty puzzles, 25 cover Biology and 3 cover Chemistry. The solutions to the word puzzles depend upon thestudent's knowing, or being able to find, a body of facts. The puzzles could be improved by having some solutions depend upon concept understanding. Some of the puzzles ask the student to name people or places that might not be mentioned in some textbooks. If the class- room text does not give an answer, the teacher would have to provide other refer- ences or verbally fill the void.

A It is reassuring to see that in this second edition the authors have taken careful note of many of the criticisms leveled a t their first effort. There is no dauht that this newer version represents a substantial improvement which goes beyond a new ewer picture.

There have been some substantial changes in the presentation although the format and chapter sequence remain basically the same. The first four chapters present fundamental concepts. The next five chapters discuss various classes of organic compounds and their reactions. Chapter 10 is a fourteen page summary of the first nine chapters, and the final eight chapters present relevant special topics with a decided emphasis on biulogi- cally important molecules.

Problems have been included in the text and also a t the ends of the later chapters where they had been omitted previously.

Same synthetic problems have been added. Very brief answers are provided to the odd-numbered problems only. A larger type and higher quality paper have been used to make the book more pleasing to the eye.

The first chapter on bonding has been substantially rewritten togive the student a somewhat clearer picture of this most fun- damental concept.

The discussion of optical isomerism has been moved from Chapter 2 to Chapter Several chapter introductions have been rewritten in a more understand- able fashion, particularly the one on Acids and Bases.

For example, the "half-assed resonance analogy" regarding mules, donkeys, and horses has been lifted from Morrison and Boyd, and on page 93 reference is made to"aeraaol repellents. In general, it is this reviewer's belief that the text should be competitive in the very prolific market to which it is directed.
