Arithmetic and simple algebra are the only math prerequisites. Learning objectives appear a t the beginning of each major section and, together with chapter summaries, should prove helpful in guiding the attention of the reader t o the main concepts involved.

T o estahlirh an easy-to-read format, new terms are lirted in bold type and defined aisimply as paiihle. Thew ikaglwsary in the text uhich the student ran use to review the definition uf any term forgotten. As much as possible, everything has been reduced tosimplerules. For the first time in over 40 years, significant digits have been made intelligible. Simple diagrams are often used to explain mare complex topics. The number of examples in the text is adequate, and the examples are clearly explained. Each sample problem has explanatory material outlining the thought process leading to eaeh step. Inaddition, the page margins listproblem numbers that relate to the topic discussed. Thus, the student can read the text and know which questions and problems are related to the readings, gaining immediate feedback on the level of understsnding. Additional problems are given in the accompanying study guide, which also contains chapter objectives, a list of new terms, a chapter overview, a self-test, and the answers to the self-test. A 6psge treatise on "How to Ace Chemistry" is also included and is well worth the time spent reading it. The examples and concise explanations will he an asset to students seeking extra help on particular topics. As a supplemental text, it is well done.

This text is designed for use in undergraduate nursing programs and related fields. The pages devoted t o general chemistry, organic chemistry, and biochemistry cover too wide a range of content for a one-year general high school chemistry course. Many high schools do offer a second year of chemistry that includes oreanie and hiachemistry, and these schools conce&hly could use this text. It is not as difficult to read and understand as are the standard textn based upon CHEM Study. Its main drawback is that all examples and applications are drawn from the health sciences. That might he desirable for the nursing student who has already taken a general chemistry course in high school and is looking for the applications t o the health field, but the high school student needs a broader point of view. This narrow outlook can be seen,for example, in Chapter 2; radioactivity is discussed there. hut it is done with relation to w e e r theraov. A table shows uses and bricks, and a sponge. The only other example of Boyle's Law is an inflammed Eustachian tube. There is no descriptive inorganic chemistry in the text except for two pages devoted to periodicity. Petroleum refining is given three sentences, the use of alkanes for gasoline is given one line in a table, hut a whole paragraph is devoted to the use of Vaseline" for treetine diaoer rash.

In the chapter on electroche&stry, a section is devoted the electrochemistry of life; such processes as the occurrence of redoa reactions in the res~iratarvchain and the electrical conduction of nerviimpulses and muscle contractions are discussed. Other chapters discuss the function of compounds occurring naturally in the hody-amines, narcotics, amphetamines, and hallucinogens.

1 This text is remarkably coherent and readable for a text which covers this breadth of material. The authors have managed to extract

the essence of the topics from the detail which frequently obscures the overview for the typical student. This has been accomplished a t little expense to necessary theoretical and descriptive material. This text stresses chemistrv of livine svstems. It is well intemated with most principles relating to physiological and health science applications. The excellent diagrams and analogies are clear and concise. The most likely application for this teat a t the high school level
