The first term of the second series (Helios) represents an 

 orbital node in which the time of revolution would be synchro- 

 nous with that of a solar half-rotation. This, as I have already 

 said, is equivalent to the time in which the continuous accele- 

 ration or retardation of Sun's superficial gravitation would 

 communicate or overcome the velocity of Light. In order to 

 maintain equality of areas, the time of rotation in an expand- 

 ing or contracting nucleus should vary as the square of radius. 

 But g varies inversely as the square of radius ; so that gt 

 should be constant at all stages of solar condensation, past, 

 present, or future. 



The second term of the series (Themis) represents an orbital 

 node in which planetary revolution would be accomplished in 

 a sidereal day, or synchronously with Earth's rotation on its 

 axis. The closeness of its relation to Earth, and its accordance 

 with the laws of harmony, are both fitly designated by its 

 name — Themis having been regarded as the daughter of Heaven 

 and Earth, and as the goddess of law and order. 



The third term of the series (Eunomia) represents an or- 

 bital node in which planetary revolution would be accom- 

 plished synchronously with Jupiter's rotation on its axis. Its 

 designation has also a double fitness ; for Eunomia was the 

 mythical daughter of Jupiter and Themis, her name signifying 

 " good government." 



The fourth term of the series (Phaos) represents an orbital 

 node in which planetary revolution would be synchronous with 

 two planetary revolutions at Sun's surface. 



The fifth term of the series (Lychnis) represents an orbital 

 node at which Herschel's theoretical " subsidence " would 

 give Sun's present velocity of rotation. 



The sixth term of the series represents a node which is some- 

 what within Sun's apparent surface, or at its actual surface, pro- 

 vided the depth of the photosphere is 1 per cent, of Sun's radius. 

 The one hundred and eighty-seventh term of the first series 

 represents an orbital node at the upper surface of Sun's pho- 

 tosphere. Its harmonic denominator represents the ratio of 

 Sun's mass to the aggregate planetary mass. 



We see, therefore, in the second series, not only the nodal 

 influence of the largest two bodies in the system (Sun and
