book reviews
throughout all phases of the text does make for interestine and informative resdine:
found in most general chemistry textbooks, since industrial processes are described rather in detail wherever it is possible throughout the book. In fact; the instructor using the hook will have to pick and choose some of the material and perticulmly only portions of the exercises since over a thousand are available at the end of the chapters. Teachers of beginning college chemistry who are concerned with the problems of accepting average students into a program which is destined to serve as a science requirement and in preparation for more chemistry should find this book very helpful. The explanations me clear and concise, and the illustrations are particularly well done. The separation of the problem exsmples from the text by a colored line, emphasizes the importance of the quantitative nature of chemistry and can be used extensively, or left out by choice. The inchion of the features mentioned above, plus the absence of typographical errors and misstatements makes it easier for the student and the teacher to select an adequate program for general chemistry.
presentation. There has been considerable reorganiaation in the presentation of material. C h a p ters have been shifted around, and some topics have been placed in new and s e p arate chaoters. The text now consists
in the earlier text. Major changes are found in the following chapters: Density and Specific Gravity (material now in a separate chapter), Spectrophotometry (formerly, Colorimetry), Theory and Praetice of Titrimetry Based on the Formation of a Precipitate, Theory and Practice of Titrimetry Based on the Formation of a Slightly Dissociated Compound (material on precipitates and slightly dissociated compounds was previously found in a single chapter). The remaining chapters include revisions of various degrees; such revisions including the deletion of some topics (for example, titrstions with bromate and indirect analysis), plus the inclusion of new topics (for example, single-pan balances and relative standard deviation). JAMESF. CORWIN As in the earlier hook, answers to the numerical problems are not included.

New laboratory experiments include the determination of aluminum in brass, using EDTA, and determination of calcium and magnesium in the analysis of limestone, using EDTA.

mentioned above are not serious ones; the present hook does not differ markedly from the trsditional texts currently available and compares well with them. The book contains sufficient material for a onesemester or two-quarter course in quantitative analysis for freshmen or sophomores (it is used a t Iowa State University as s. text for a two-quarter course giien to freshmen students majoring in chemistry), but does not contain sufficientmaterial for a. second or more advanced course, such as "instrumental analysis."

As Professor Kenner states in his Preface to "Analytical Determinations and Separations," the chemistry curriculum is in a. state of flux. In addition, he is absolutelv correct in that the ouantitative
ate chemistry courses. Here yesterday, gone today, back in another spot tomorrow. No one can say with certainty what the sndytical course will he or where it will settle down in the "newer" chemistry curricula being developed at this time. This uncertainty is one of the causes for the somewhat unsatisfactory nature of the books (or book) being reviewed. In discussions with various people, one acquires the feeling that the economio difficulties of the publishing industry have led many publishers to try to make sure that every text-hook is suitable for all possible markets. Professor Kenner correctly indicates that there is a need for a lower level quantitative analysis book than some of those presently available. Hawever, a. book of this sort naturally would have a limited market. Therefore, somewhere along the l i ~Professor , Kenner has been prevailed upon to add sections an several of the more sophisticated analytical techniques and we are back to ground zero again. We now have a book covering the elementary principles in a really excellent manner, with chspters on spectrophotom(Continued on page A4O)
