of influences which may be regarded as meteoric. Indeed, Herschel’s 
subsidence-theory recognizes the continual activity of such influences, 
provided we consider every particle which is falling towards the sun as 
meteoric, If we still further regard the luminiferous sther as material, 
we may consider ourselves as living in a condensing and rotating nebula. 
445, Linkage of Sun, Harth, Jupiter and Saturn. 
The influence of simple primitive subsidence, which was so strikingly 
exemplified in the mass-ratios of Neptune and Uranus (Note 488), is no 
less evident in the four important cosmical bodies which represent, re- 
spectively, the chief centre of nucleation (Sun), the chief centre of con- 
densation (Earth), the primitive nebular centre (Jupiter), and the centre 
of inertia of the primitive planetary system (Saturn). This influence is 
shown by the equation 
Sun x Earth x Saturn = Jupiter’. 
Substituting in this equation the harmonic ratio of Sun to Earth (829196) 
and Bessel’s estimate of Sun -- Saturn (3501.6), we get for Sun + Jupi- 
ter 1048.5. 
446. Saturn’s Secular Hecentricity. 
The mutual actions and reactions, among the four cosmical masses 
which were introduced into the foregoing note, are still further shown by 
the connection of the orbital periods of Earth and Jupiter with the secular 
eccentricity of Saturn, 
This connection is shown by the proportion 
4382.5848 : 365.2565 ;: 1: .0848045. 
Stockwell’s estimate of Saturn’s secular eccentricity is .0848289. 
This differs by less than s'; of one per cent from the harmonic estimate. 
447, Primitéve Phyllotactic Relations. 
The centre of a nebula which is bounded at opposite extremities of its 
diameter by the secular aphelia, or loci of incipient subsidence, of Nep- 
tune and Uranus, according to Stockwell’s estimate, is 4.8952. This differs 
by less than } of one per cent from Jupiter’s secular perihelion, or locus 
of incipient nebular rupture. The mass of Neptune is approximately 
of Earth’s harmonic mass. Uranus is almost precisely °; of the Uranus- 
Neptune belt. Saturn is almost precisely ;°; of the Jupiter-Saturn belt. 
The numbers }, 2 X 4, 44; and 4, are all phyllotactic. The values which 
fully satisfy these mass relations are 
Sun + Neptune : 19352.'76 
Sun + Uranus 22578. 22 
Sun -- Saturn 8490.71 
Sun + Jupiter. 1047.21
