At last, a choice
in low temperature ashing from
We've brought plasma machines within the reach of every laboratory — large or small. The new 150 watt IPC 1001 has two large ashing chambers that give you sample handling capacity up to 1.0 gram per hour.
When you need faster, larger capacity ashing, IPC offers larger power units . . . 300, 1000, up to 2000 watts. Pick the IPC plasma machine that's right for you. Then, choose up to six ashing chambers. You'll be able to ash up to thirty 1-gram samples simultaneously . . . faster than 3.60 grams an hour. Action of every IPC Plasma machine is so gentle that such fleeting elements as arsenic, selenium, and zinc aren't lost. And, there's no contamination from outside agents when ashing. In addition to plasma machines, IPC offers a wide selection of plasma systems for R&D and production work. You can also choose from a complete line of accessories for faster ashing and easier sample handling. If you need high speed, versatile, easy-to-operate plasma machines, we'll help you select the one that's right for you. Write International Plasma Corporation, P.O.

ANALYTICAL CHEMISTRY, VOL. 42, NO. 1, JANUARY 1970
with articles on both optical and electron microscopy in each volume. In the present volume the two articles on optical microscopy reflect the growing interest in variable magnification and in quantitative measurement, respectively. Topics include a comprehensive account of the design and operation of various types of zoom systems, many of them hitherto only described in patent literature; also described in similar detail are some of the techniques of stereology, particle size measurement, and related topics. Other topics include an adaptation of autoradiographic procedures to the special conditions of electron microscopy, emphasizing the precautions necessary if meaningful results are to be obtained. A description of the potentialities of the very new procedures for carrying out small angle electron diffraction in the electron microscope, equally applicable to the study of magnetic domains and of long spacing in macromoleculcs, is included in this volume. Electronic Structure and Chemical Binding: With Special Reference to Inorganic Chemistry. Oscar Knefler Rice, xviii 4- 511 pages. Dover Publications, Inc., 180 Varick Street, New York, N. Y. 10014. 1969. Paperbound. $3.75
This book is an unabridged and slightly corrected re-publication of the work originally published in 1940 by McGraw-Hill Book Co., Inc., to which the author has added a new preface. Although some advances have been made since this book first appeared, the basic theory and the experimental material it presents remain unaltered in many respects. The few corrections in experimental data and improvements in the theoretical analysis of specific compounds are clearly indicated by the author in the new preface. The application of modern atomic theory to chemical binding was new in 1940, but since then it has become one of the standard approaches to the subject. For this reason this book remains a basic text in the field, and can be used to great advantage by all teachers and advanced students of chemistry. Correction The editors of the 1969-70 ACS LABORATORY GUIDE have asked us to correct an error that appeared on page 420LG. Under the Inorganic Chemistry section appeared the listing "Carbon14" by Vernon F. Raaen, Gus A. Ropp, and Helen P. Raaen. Obviously this book should have appeared in the Organic Chemistry grouping beginning on page 423LG. We regret the error.
