a- Jupiter's locus of incipient subsidence (secular aphelion), is nearly 

 a mean proportional between Neptune's locus of incipient subsidence and 

 Earth's semi-axis major. 



^. Jupiter's mean subsidence-locus (mean aphelion) is nearly a mean 

 proportional between Xeptune's locus of incipient subsidence and Earth's 

 mean projectile locus (mean perihelion). 



y. Jupiter's mean subsidence-locus is nearly a mean proportional be- 

 tween the semi-axes major of Mars and Uranus. 



8. Jupiter's semi-axis major is nearly a mean proportional between the 

 mean projectile locus of Mars and the semi-axis major of Uranus. 



e. Jupiter's semi axis major is nearly a mean proportional between the 

 incipient subsidence locus of Uranus and the incipient projectile locus 

 (secular perihelion) of Mars. 



^. Jupiter's mean projectile locus is nearly a mean proportional between 

 the incipient projectile-locus of Uranus and the mean projectile-locus of 

 Mars. 



Tj. All of Jupiter's orbhal loci are at centres of explosive oscillation (f) 

 of orbital loci of Saturn. 



0. Jupiter's mean subsidence-locus is at the nucleal locus of a condens- 

 ing nebula, of which Saturn represents Laplace's atmospheric limit and 

 Earth is the centre of condensation ; Earth's semi axis major being the 

 unit radius, and Laplace's limit varying as the | power of the nucleal 

 radius. Accordances tj and 0, which are the closest of all, are especially 

 interesting on account of the variety of indications wh-ch they give of the 

 harmonic influence of luminous undulations upon the four great centres of 

 nucleation, condensation, nebulosity and planetary inertia. 



The following table shows the closeness of agreement between the har- 

 monic values and Stockwell's. 



331. Photodynamic Significance of the Temperature of Space. 



Sir John Herschel estimated the absolute temperature of interstellar space 

 as about one-half as great as Earth's mean superficial absolute temperature. 

 If the former temperature is due to stellar radiations, every star must have 

 opposite hemispheres which are exposed to different temperatures, as well 

 as to different gravitating tendencies. The fundamental equation ot ve- 

 locity (Note 321), may be fairly presumed to be universal, so that all
