 The fallacy of this class of engines we shall expose in con- 

 junction with the next class, as the same misconceptions lie to 

 a considerable extent at the root of both. 



Class V. — Revolving Mechanism svibstituted for the crank 

 of the common steam-engine, for the purpose of obtaining from 

 the reciprocating piston a rotatory effect otherwse than by the 

 crank, and in a better manner than by the crank, forms a class 

 of inventions involving fallacies similar to those in which the 

 revolving piston has originated. These two may therefore be 

 considered together.
