The phenomenon of the production of motion by heat has not been considered from a sufficiently general point of view. We have considered it only in machines... the phenomenon is... incomplete. It becomes difficult to recognize its principles and study its laws. ...he principle of the production of motion by heat... must be considered independently of any mechanism or... particular agent. It is necessary to establish principles applicable not only to steam-engines but to all imaginable heat-engines, whatever the working substance and whatever the method by which it is operated.
