Of the fifty puzzles, 25 cover Biology and 3 cover Chemistry. The rest use Astronomy, Physics, Weather, Oceanography, Geology, and Space Travel as subjects. 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.
The authors state that the puzzles could he used as an introduction or a summary of a unit of study. These puzzles are another version of the old fashioned work sheet, ex- cept that this time the student should have some fun.

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. The key word marginal outline has been omitted while the breakdown of subject headings and sub- headings has been improved.
The relatively random use of green in the illustrations has been abandoned at little or no cost to the understanding. Each chapter ends with a hrief but useful summary. 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.
