lationships is found in Volume 3, and a 150-page addendum brings the references for the series up t o 1956. On the whole, these latter two volumes will be a goad deal less useful. The passion for completeness has resulted in the inclusion of an exoess of superffuous dat.a and unneeded detail. The many references to biologicd a.pplications, for example, seem out of place in a work designed for the analyst. More serious, the noncritical listing of d l reported determinations makes it difficult for the chemist to select the best reagent and optimum conditions far the determination of a given metsl. The usefulness of these two volumes would be increased considerably by a summary of the selectivity of all these derivatives. RICHARD K. HILL

PAPER ELECTROPHORESIS: CIBA FOUNDATION SYMPOSRTM Edited by G. E. W. Wostenholme and Elaine C. P. Milar, Ciba Foundation, London. Little, Brown and Co., Boston, 224 pp. 14.5 X 21 cm. 1956. xii $6.75.

INJULY of 1955 the Ciba Foundation sponsored a symposium an paper eleetrophoresis in London. Participating were researchers from various countries. This book includes the papers presented together with the discussions of them by those who attended. Since paper electrophoresis has been applied up t o now primarily in the study of changes in blood proteinn, a considerable portion of the book is devoted t o discussions of these changes. However, W. Grassmann pointed out that paper electrophoresis can be "employed in the entire fields of inorganic and orgenie substances with hoth high and low molecular weights and there is hardly any branch of chemistry in which this method cannot be or hits not been applied successfully." An example of these applications discussed is its use in the separation of some of the degradation products of vitamin BIZ. Of particular interest to chemists will be the discussions of the theory and methods of paper electrophoresis by W. Grassmann, of physicochemical aspects and their rolstionship to the design of apparatus by H. Svensson, of the analysis of separated materials by E. M. Crook and N. H. Martin, and the find chapter by E. L. Durrum on the future of tho technique. Included in the book are excellent illustrations including diagrams of various types of paper electrophoresis apparatus. The very useful hanging-curtain cantinuous paper electrophoresis apparatus is discussed only briefly. This book should prove valuable to the chemist who is using electrophoresis either in research or in teaching. ARTHUR H. LIVERMORE Rseo C o m s o ~ P O ~ T ~ AO NnD~,o o a

Each important compound is described hy short paragraphs of t e n t and extensive tables of physical constants. Data, such as azeotrape composition, are included for solvents of greatest general utility. This volume is "a. practical source of practical information," both in terms of content and organieation.

THE fifth edition of "Quantitative Pharmaceutical Chemistry" continues the fine tradition established in the earlier editions. I t hits been brought up-todate with the latest revisions of the United States Pharmscopeia, and the National Formulary. Analytical procedures hsve been revised and the methods of analysis of new drugs recently made official in the U.S.P. and the N.F. have been added. The book serves as a standard reference work for analysts in the drug industry and a t the same time provides basic information for students of pharmacy. Earlier editions have served as textbooks for standard courses in drug analysis. New ohupters on radioactivity and chromatography have been added. New material has also been added on instrumentation analysis. The question and problem lists have been completely revised. This hook will continue to he a standard work for both the classroom and the industrial pharmaceutical laboratory.

"PURE Hydrocarbons" means the contents of bottles or drums, as used by industry. Commercial and proprietary names are used; data pertinent to their use by manufacturers rather than researchers are included. Aliphaties are listed on 93 pages, aromatics on 72, and 7 psges of dsta on terpenes are included. The title, "Handbook of Solvents, Volume 1," has been changed to "Source Book of Industrial Solvents, Volume 1" to conform with that of the other volumes of the series. Volume 2 has sections devokd to fluorinated hydrocarbons (72 pages), chlorinated hydrocarbons (121 pages), brominsted hydrocarbons (43 pages), and a brief 7 psges on iodine compounds.
HOW TO DO AN EXPERIMENT Philip Goldstein, Department of Biology, Abraham Lincoln High School, Brooklyn, New York. Harcourt. Brace and Co.. New ~ o r k , 1957. 192 i p . 4 3 figs. 15 X 21.5 cm. $2.60. THEauthor holds the view that the only good way for s. student t o get started on the study of science is by infection. This infection might come from an enthusiastic teacher who will help unfold the story of ". . .the amazing discoveries which scientists have made." Then says Goldstein, I really will come the questions-"Can make a great discovery some day? Can I learn to experiment? Can I do an experiment now?" He goes on to explain that the purpose of his book is to help the student get started by facing up to these questions. The opening section looks carefully a t the chsracteristie general pattern of investigations in science, that is, the scientific method. A careful analysis is made of several interesting cases from history. Part 2 has to do with how information ia obtained, the avenues which may be followed. The best chapter is the one in which the author discusses in some detail the important elements of a planned experiment and then illustrates with several well-chosen examples. Part 3, How to Carry On an Investigation, is the largest and perhaps most helpful section. I t begins with a. visit to a science fair followed by some 20 chapters, each one dealing with a d i K e ~ n taspect of investigation. All of this is done in a very interesting way, with data and reports taken from the work of students and scientists. For example, Chapter 20, Recording the Observations, contains a reproduction of part of an actual student "log" of experiments conducted with onion plants in order to determine the effect on their growth of fertilizer injected directly into the plant. On reading these dsta, one develops the feeling of wanting to "go right out and try it." Tho hook ends with a good chapter an the fundsmentals of statistirs and another containing an excellent bibliography. The publisher states that this book is intended for use in any science course in the junior or senior high school. The style of writing is so simple and logical, and the illustrations so interesting, that it probably is useful in so wide an age range. I t will prove very helpful in the high school science course where student science projects are encouraged.
