Beschreibung
Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Mechanical inventors speak of a machine as efficient when it does its work without loss of power. If a hundred pounds of steam pressure are applied to it, the full hundred pounds are accounted for in valuable engine power. There _is no waste. Any instrument is efficient when it gets the most work from a given amount of effort.
