454 LAWS OF MOTION. 



matter which exists, possessing a natural and 

 inherent tendency, a vis insita, as it has been call- 

 ed, to obey certain rules of rest, or of motion of 

 unity, or of union according to the particular 

 class to which it belongs ; by which it is made 

 to describe, under the same circumstances, the 

 same phenomena, by which solids fall to the 

 earth rivers flow into the ocean, by which 

 gaseous bodies expand and swell on the surface 

 of both, and are participated by the solar rays, 

 which warm and illuminate the whole. 



It is through the efficacy of these rules, ; that 

 the planets with order and regularity move 

 through their allotted spheres,- the changes in 

 the seasons are formed, and tke divisions of time 

 established. These rules which have existed 

 from the moment of the creation, and which, it 

 is probable, will continue to exist until time 

 shall be no more, constitute the Laics of Nature, 

 or rather the instruments, or agents, which the 

 GOD OF NATURE employs in the physical go- 

 vernment of the material world.
