[The ABC's of Chemistry] contains the usual definitions that would be expected to be of help to anyone taking a first course in general science; it is clear, concise, and accurate. However, the most useful feature of the book is the numerous tables that are to be found through the body of the list of definitions and in the special section at the end. Under "hardness," for instance, is an excellent table of the hardness of minerals—a much better one, in fact, than is to be found in the usual textbook. The periodic table on pages 68 and 69 is an unusually clear and attractive one.
