Harmonic Xodes in the Solar System. 



II. Correlations of Planetary Mass. 



The Sun's surface, which is the seat of the mutual action and reaction 

 of its attractive and radiating forces, is also the fulcrum of a lever which 

 would balance the solar and planetary masses if the latter were placed 

 near the outer asteroidal limit, or near the linear centre of oscillation of 

 Jupiter's radius vector. The outer end of the lever is also at a distance 

 (3.513 0), at which the velocity of revolution is equivalent to the velocity 

 which would give Jupiter, at its perihelion, a parabolic orbit. These 

 harmonies seem to point to harmonies of mass, which, by means of com- 

 mensurate momenta or moments of inertia, may help to sustain the equi- 

 poise of the system. 



I have already pointed out, in my note on "Oscillatory Forces in the 

 Solar System" {ante, p. 140), some striking, and, I believe, entirely novel 

 evidences of such harmony, which seem to be attributable to the same 

 play of elastic forces which has assigned to each planet its appropriate 

 position. There are still further and somewhat analogous relations be- 

 tween the centres of gravity of the two principal pairs of planets, as 

 well as between solar and important planetary positions, which I submit 

 as additional confirmation of the influence of sethereal vibration.
