FROM THE PREFACE: “In the twenty. first annual issue of this work some important changes have been made. The notes on electrical transmission of power have been omitted, and this has allowed us to introduce a deal of new matter. In particular, attention is directed to a lengthy section on Condensing Plant and to another on the important subject of Superheating. The matter on Reverberatory and Reheating Furnaces has been rewritten and greatly extended, a section on Friction Clutches has been introduced, and several new tables have been added. These pertain to such matters as Morse Standard Tapers, British Standard Pipe Flanges, Pipe Threads, &c. Some of the standing tables have been modified, and will be found more convenient to use; several new illustrations have been introduced, and the whole work revised…”
