NEW BOOKS European design and manufacture. The fundamentals of photography and photographic spectrophotometry are included. The second and largest section encompasses the analytical techniques of emission spectroscop3r. Qualitative, semiquantitative, and quantitative procedures are discussed for the analysis of samples in solid and solution form. The manipulative descriptions follow the format of sample preparation, obtaining the spectrum, and its measurement and interpretation. "Special analyses" involving microprocedures are described. A brief discussion of sample size, time per determination, and precision is followed by selected illustrative procedures for the quantitative estimation of aluminum, iron, and steel. An extremely useful appendix of physical constants, definitions, formulas, and spectroscopic computations concludes the work. This excellent text is directed at the novice. However, by virtue of its illustrativeness and unusually orderly presentation, few experienced spectroscopists would not benefit from a perusal of this book. Synthetic

The new edition contains more than 3000 pages of data and consists of five major sections: mathematical tables, properties and physical constants, general chemical tables, heat and hygrometry, and quantities and units. Xew or revised data appear on physical and chemical constants of the rare earths, heat of formation of inorganic oxides, mean specific heats of liquid metals and liquid salts, miscellaneous properties of common refrigerants,

Osborn. ix + 194 pages. Macmillan Co., 60 Fifth Ave., New York 11, N. Y., 1956. S6.00. This book is designed to sum up and review the latest knowledge and developments in the fast-growing field of synthetic ion exchange. It covers the practical and theoretical aspects of all phases of synthetic ion exchangers, including the latest types of selective resins. Ineluded is a chapter on the analytical aspects. Rather than outline specific analytical applications, the book deals with the various ways in which these resins can be used in analytical chemistry. A classified bibliography lists 2000 original papers published during the past 5 years.
The advantages of automatic burettes are waiting for you here. Here's how to have them where they belong—in your laboratory. First, check the index of Coming's Catalog of Custom Apparatus. It refers you to a listing of five different kinds on pages 16 and 17. You'll learn that the tubing is precision bore, precisely graduated to Class A accuracy tolerances. Also, that the one you need is made of PYREX brand glass No. 7740, with all its useful properties. If none of the 5 automatic burettes listed is quite the one you need, dash off a rough drawing (showing dimensions and quantities needed), send it in and we'll make it up. Our Special Apparatus Department devotes all its time to turning out ware in the PYREX brand glasses — to Coming's critical quality standards—on special order.
