This rather large book is a record of a "Symposium on Temperature--Its Measurement and Control in Science and Industry," held in New York, November 2, 3, and 4, I939, under the auspices of the American Institute of Physics. The Symposium was planned with the following purposes in view. (I) Co6rdination of the treatment of the subject of temperature in the several branches of science and engineering, (2) review of fundamental principles and a recapitulation of recent progress, (3) accumulation of contributions for a comprehensive text to be published after the Symposium, (4) emphasis on the importance of temperature as a branch of physics, (5) improvement of technical curricula through making the latest information available. The National Bureau of Standards, National Research Council, co6perated extensively in making the Symposium a success, as well as officers and committees of various engineering societies.
The arrangement of the papers in the book is under t 3 different classes. They are temperature and temperature scales, precision thermometry, education, natural sciences, temperature in biology, temperature and its regulation in man, automatic temperature regulation and recording, special applications and methods, general engineering, metals and ceramic indnstries, oil industries, optical and radiation pyrometry, and thermometric metals and alloys. Some I25 papers were presented and informally discussed by the best authorities on the subjects. The book also contains twenty-five tables of generally useful data, a Glossary of technical terms and complete author and subject indexes. Much of value can be found in this book by chemists, biologists, geologists, engineers, physicians and those bearing many other professional designations.
