10. The foregoing postulates are all equally true, whether the centri- 

 petal impulse originate in a thrust, or in a pull. 



11. We have no direct evidence of any primitive pull, but we have 

 evidences of radiating thrusts of light and heat from stellar centres. 



12. In all known cosmical motions, the centrifugal and centripetal 

 forces act under such laws of equ.ilibrium, that the apparent pull of 

 gravity may be explained by the difference between external and inter- 

 mediate radiating thrusts. 



13. We know of oscillations in the ajthereal sea, propagated with v ' 

 (the velocity of light). The communication of an exceedingly minute 

 portion of that velocity to inert particles, would be sufficient to produce 

 all the phenomena of gravitation. 



14. The greatest manifestation of gravitating force in our system 



{g at Sun's surface) = 875.618 ft. = 875.618 X 584,400 = 511,711,159 



mean light- waves per second. There being 592 (10) mean light-waves 



511,711,159 1 



per second, that force could be produced by -,7 = Ts 



^ -^ -^ 592 (10)'' 1157 (10)'' 



of the mean velocity of each light-wave. 



15. If gravity were propagated with infinite velocity, and any inert 

 mass were concentrated in a point, a body falling to that point would 

 obtain an infinite velocity. 



16. If gravity is the resultant of oscillations of finite velocity, and if 

 solar rotation, planetary revolution, and solar motion in space, are all 

 resultants of gravitating action, their velocities should'all be limited by 



v' (the velocity of the primary efficient oscillation). 



17. In a homogeneous circular disc, of infinitesimal thickness, g ex dis- 

 tance from centre. 



18. If such a disc were revolving in a circular orbit, under the 

 combined influence of tangential and centripetal thrusts, in a slightly 

 compressible tethereal ocean, it should rotate as well as revolve, the 



limit of possible rotating velocity being «' . 



19. If the supposed disc should acquire such a velocity that at the 

 periphery «' = v" ^= -[/gr, the same equations would be true for every 

 particle in the disc. 



20. In a sphere or spheroid, the superficial centripetal thrusts should 

 produce an increase of density at and towards the centre. 



31. The ratio of the rotating action of an sethei'eal stream on the 

 equatorial plane of a nebulous sphere, to the propelling force of the same 

 stream acting on the spherical surface, is tt?' : 4,t?'", or 1 : 4. 



22. In a rotating and revolving sbar, planet, or satellite, each equa- 

 torial particle oscillates in waves which have a height equivalent to 

 twice the distance of the particle from the centre of gravity of the rota- 

 ting body.
