And here's a book to supplement WINDOWS ON THE WORLD with up -to-the-minute data on modern science, in its application to daily life. With a brief historical background, on each subject, the author brings us up to date on such varied matters as the microscope, the thermometer, weights, measurement, internal chemistry, practical application of science to industry, industrial chemistry, lighting, etc. Very readable and amazingly far reaching in interest.
