The projections of hydfogen in solar explosions, together with the many- 

 indications that hydrogen represents the first known stage of sethereal con- 

 densation, make it probable that Earth's orbital projection ip = .. _ j, 



and the molecular velocity of hydrogen (v^) may also be directly dependent 

 upon photodynamic action. Such dependence is shown by the equation 



P ^h = «r- 



1,0388 

 The secular value of ^, according to Stockwell, is naao = 1.06994 ; mo- 

 lecular velocity of hydrogen v^^, at the temperature of maximum water-

 density, is ^OTH ^ ^^^^ ^^ 6094.14 ft. = 1.1542 miles ; hence v^, or Sun's 



equatorial velocity of rotation, 1.06994 X 1.1542 = 1.235 miles. Multiply- 

 ing by the number of seconds in 12.747 days (t^, see foregoing note) and 

 dividing by tt, we get 432,931 miles for Sun's semi-diameter, and 214.5 x 

 432,931 = 92,863,700 miles for Earth's semi-axis major. These relations, 

 also, are photodynamically radiodynamic, but it would be difficult to find 

 in them any evidence of thermodynamic or electrodynamic action. 



35. Ethereal, Gaseous and Planetary Densities. 



I have already given two approximations* to the comparative sethereal 

 ratio of elasticity to density, and one approximationf to the relative densi- 

 ties of aether and hydrogen. The accumulating evidences of universal 

 photodynamic energy, leading to various accordant 8ethereal, gaseous and 

 cosmical harmonies, are such as to justify another tentative step in the 

 same direction. From chemical analogy the planetary aggregations, at 

 the centres of nebulosity (^^j) and of density (//g), may well be presumed to 

 give indications of the comparative energies of condensed and of uncon- 

 densed aether. We may, therefore, hypothetically assume that

The Quotient of Sun's mass (jxq) by Earth's mass (r/g), which is indicated 

 by the foregoing note, is 332,613. This gives, for the quotient of Jupiter's 

 mass (/jj) by /^g, 317.416, and for the velocity of light, 186.538 miles. Sub- 

 stituting these values in the above proportion, and designating the densities 

 of aether and of hydrogen by 8^ and 8^, we get

 8^ = 7,242,500,000,000 d^. 



This exceeds the ratio which was deduced from sethereal and gravitating 

 interaciionf by a little more than six per cent. But in that approximation 

 the factor of terrestrial projection, -p = 1.06994, was omitted. If we intro- 

 duce this factor and increase our estimate of Earth's density about -^ of
