Sir James Alfred Ewing (1855-1935) was a Scottish engineer, physicist and cryptographer. First published in 1926, as the fourth edition of an 1894 original, this book was written by Ewing 'to present the subject of heat-engines, in their mechanical as well as their thermodynamical aspects, with sufficient fulness for the ordinary needs of University students of engineering'. The text was extensively revised for this edition, taking into account developments in relation to steam turbines, steam boilers and internal combustion engines. Numerous illustrative figures are also provided. This book will be of value to anyone with an interest in Ewing's writings, steam engines and the history of engineering.

The title essay, along with other papers in this volume, laid the foundation of modern thermodynamics. Highly readable, "Reflections" contains no arguments that depend on calculus, examining the relation between heat and work in terms of heat in steam engines, air-engines, and an internal combustion machine. Translation of 1890 edition.

"From the beginning of the eighteenth century to the high watermark of the Victorian era, the world was transformed by a technological revolution - the like of which had never been seen before. ... Thomas Crump introduces the inventors, businessmen, scientists and explorers, who all had their part to play in the story of the Industrial revolution. He looks at how its scientific, technological and political changes spread across the world to [the United States of] America, Europe, and the Empire."--Back cover.
