a:. In tendencies to reverse condensation towards Jupiter, Earth's mean 

 locus of subsidence is 4.1289304^03 from Jupiter's mean locus. This repre- 

 sents a nucleal radius for which Laplace's limit wouldbe 6.70965/93, which 

 is near the mean locus of Mars on the opposite side of Sun. 



A. In like reverse condensation, the mean locus of Mars, when in con- 

 junction with Jupiter, represents a nucleal radius for which Laplace's 

 limit would be 5.67968/)3, which is near Mercury's incipient locus of subsi- 

 dence. 



H- Taking Mercury's mean subsidence locus as final or unit radius, 

 Venus represents a nucleal radius, for which Earth's projectile locus would 

 be Laplace's limit. 



The closeness of accordance is shown in the following table :

It cannot reasonably be expected, among all the different tendencies to 

 harmonic motion, that we can immediately find all which have been 

 operative in any given case. In view of the small amount of work which 

 has been done in this field, such simplicity and closeness of agreement as 

 were shown in Notes 329-31 and 334 are very encouraging, "We have 

 already found many evidences of reciprocal or retrograde action in the 

 Neptuno-Uranian belt, of central planetary inertia in the Saturnian belt, 

 and of Jupiter's paramount planetary influence. If we regard all of the 

 dense belt of planets as originally belonging to the great central nucleus, 

 Alexander's harmony, m-^ p-^ == m^p^, may be thus modified :
