THERE IS . . . A DIFFERENCE
BOOKS PROGRESS IN
POLAROGRAPHY TWO VOLUMES Edited by P. ZUMAN, Polarographic Institute, Czechoslovak Academy of Science, Prague with the collaboration of I. M . KOLTHOFF, Department of Chemistry,
University of Minnesota Because of t h e tremendously varied aspects of theoretical and applied polarography, 45 specialists from many nations bring their experience to these volumes, to detail progress in the field, especially during the last decade. Contributions cover the full range—theoretical electrochemistry, physical, organic, inorganic, and biochemistry. T h e book is dedicated t o Dr. Heyrovsky, acknowledged originator of polarography. From t h e Dedication: " N o w a d a y s , n o chemical laboratory, be i t 'pure' or 'applied,' can afford t o be w i t h o u t one or more polarographs." The same might well be said about these t w o new volumes. Vol.1:
1962. 380 pages.

Vol.11.

QUANTITATIVE CHEMICAL TECHNIQUES OF

Stanford University Medical School Foreword by H E I N Z
HOLTER,
Carls berg Laboratory, Copenhagen Although specialized methods have received some treatment in the literature, quantitative chemical techniques of histo- and cytochemistry have been given much less attention than they deserve. This book brings them up t o date in compact form. Even so, it requires two volumes. These outline t h e main advantage of t h e quantitative chemical approach—its versatility in furnishing analytical data on practically t h e whole array of chemical components and activities in biological material. Vol. I covers preparation of biological sample; measurement of amount of sample; apparatus and manipulation; gasometric, electrometric, dilatometric, and fluorometric techniques. Vol. I:
1962. 482 pages. Vol.

One test tube is made of glass, the other, Vitreosil pure fused quartz. Most glass deforms at low temperatures where Vitreosil will withstand continuous operation at temperatures up to 1100°C for extended periods of time. Unlike glass, Vitreosil can handle most common acid and corrosive materials in liquid or gaseous forms, even at high temperatures, with no reaction to the quartz.
