CONSIDERATION OF TESTED DEVICES 



The device which first produces the greatest interest is the one indicated 

 in Fig. 5. In fact, it is perfectly balanced, moves forward on the floor, and 

 climbs an inclined plane. A small device of this kind, held in the hand, gives 

 evident proof of the possibility it has for generating a substantial propulsive 

 thrust for each turn of the motor shaft.
