underfitanding of the physical world, and development of the ability to apply the scientific method has been fulfilled by a. collection of 90 experiments. These have been grouped into 20 sections each containing related material which provide a. choice of several experiments for eaeh of the general subjects studied in an elementary chemistry course. Eleven appendixes containing all of the usual tables and directions far making up the solutions make the manual very complete. The traditional approach to qualitative analysis has been abandoned in favor of studying the properties of the elements in groups as suggested by the periodic table and then providing for the application of this information by analysis of simple salts and mixtures as chosen by the instructor. Each experiment containa hlank spaces for fill-in answers and each may be detached and turned in for grading purposes. The all-purpose nature of this manual coupled with the ease of grading, makes it a good choice for large classes. It would he especially useful where the larger class could be subdivided into groups with the same background, general ability, or need far a type of preparation in elementary chemistry. JAMES F.

TUIS manual is designed for Use with s. textbook that places more emphasis on organic and physiological chemistry than ir usual in the average elementary course. Each experiment eonbins blank spaces far fill-in type answers and no extra notebooks or papers are necessary. The order of presentation of the msterial follows that of the author's own textbook, "Chemistry, Visualized and Applied." Of the 26 experiments, the fist 12 are inorganic and deal with the properties of m a t e d in solution, the remainder are concerned with material that is organic or physiologiesl in nature. Teachers who have the problem of organizing the lrthorstory work for courses in chemistry, for nursea, for laboratory techniciam or for home economics students, would 6nd this manusl useful. JAMES F. CORIVIN
procedures are designed for use even with students having no previous laboratory experience. Selection of experiments within an exercise rather than selection of exercises offers comprehensive coverage of the laboratory work. Qualitative analysis as a subject has been integrated into the study of the elements and ions as groups rather than the traditional approach. Teachers who favor the written report and who wish a eomplete coverage of elementary chemistry in the laboratory will find this manual helpful. JAMES F. CORWIN

T H I manual ~ which contains 46 experiments is de~ignedto accompany Pauling's "College Chemistry," and references are made to particular chapters in the textbook to whieh eaeh experiment applies. Four extensive appendixea cover all necessary tables, methods of calculation, and directions far preparation of experiments. Laboratory safety is emphasized by numerous, well-chosen illustrations. These illustrations, along with graphic representation of chemical principles and illustration of laboratory setups, make this mi~nualoutstanding. Although the manual is written to accompany a. particular book, the material covered is very similar to that whieh appears in most general chemistry.texthooks and, with proper selection can he made to fit any course. Teachers who like a different and more modern approach will find that this book meets their expectations. JAMES F. CORWIN A ~ n o c nC o m a o e Y ~ m o wS ~ m w a s ORIO ,

Tma collection of 43 exercise8 represents a larger number of actual experiments. Elements having the same general properties are studied as a group rather than separately, and experiments illustrating the asme general principle are found in the same exereire. Report blanks that may he detached accompany each of the quantitative exercises hut no fill-in reports are included. The +&hand sides of most of the pages in the book are left blank for writing up the experiment in the farm suggested by the individual instructor. Six appendixes provide the necessary tables and directions for solution preparation. The experimental material in this manual covers all of the usual u-ork in general chemistry, and the explanations of the
provided for throughout each experiment and the pages may he torn out for grading purposes. Five very complete appendixea provide tables and descriptions of the necessary solutions. This manual offers not onlv a comvlete coveraee - of lnhoratorv experiences, but also a selection of demonstration experiments that may be used in class. The procedures are designed in general far those students who have little or no laboratory experience. Teachers who prefer the traditional approach to general chemistry and like a complete plan of demonstration and laboratory experience for their students will find this manual useful. JhMES F CORWIN
