This is a laboratory manual containing 73 experiments designed for use either as student experiments, as lecture demonstrations, or as a combination of both. Sufficient ohoice and variety is included to allow for selection or alternation of experiments. Nine experiments require no laboratory work. Only a few emeriments involve quantitative technique. Emeriments are grauped in eight units-of related interests. No qualitative analysis is included. This manual is written for terminal students of average ability with no previous experience in chemistry, Explanstions and directions are detailed with many questions regarding all phases of the work. The emphasis on descriptive material make8 this book more suitable for students with nonmathematical interests such as agriculture and home economics. Pages are perforated to hand in and are punched to fit a standard note hook. Also included in the appendix are lists of apparatus needed and quantities of reagents for ten students.
THEREare 48 experiments of approximately equal length in this manual. Directions are complete and easily understood, preceded by disoussion of principles involved and followed by review questions and problems. Spaces are included for results and answers to quentions. The arrangement of the book is such that pages must be left attached and the whole book handed in for correction. No quslitative analysis and only three organic experiments are included. 0

THIS workhook is intended for use as a supplement to any regular textbook in general chemistry. I t supplies more detailed direotions about use of symbols, formulas, equations, and the solving of problems of all kinds than most textbooks do. In each section of the hook there is a review of the principles involved, examples of each kind are solved with accompanying explanation, sets of practice problems are given with answers, and
