THE THEORY OF THE HEAVENS. 39 



through all Space. First Movement arising through 

 Attraction. Beginning of the Formation of a body 

 in the point of strongest attraction. Universal Falling 

 of the elements towards this Central Body. The 

 Force of Repulsion in the finest particles into which 

 matter has been resolved. Altered direction of the 

 falling motion through the combination of this force 

 with the former force. Uniform direction of all 

 these movements towards the same region. Tendency 

 of all the particles to press to a common plane, 

 and to accumulate there. Moderating of the Velocity 

 of their Motion to an equilibrium with the Gravity 

 of the distance of their place. Free revolution of 

 all the particles around the central body in circular 

 orbits. Formation of the Planets out of these 

 moving elements. Free motion of the Planets formed 

 therefrom in the same direction in the common 

 plane ; those near the centre almost in circular 

 orbits, and those further from it with increasing 

 degrees of eccentricity. 



SECOND CHAPTER. 



Treats of the different density of the Planets and the 

 relation of their masses. 



Cause why the near Planets are of a denser nature than 

 the more distant ones. Inadequacy, of the explana- 

 tion of Newton. Why the central body is of a lighter 

 nature than the globes revolving nearest it. Relation 

 between the masses of the Planets according to 

 the ratio of their distances. The cause why the 

 central body has the greatest mass deduced from the
