The material a terrestrial appendage — its rarity, '14. 



The light, to a great extent, transmitted light. Observers at diverse stations see different portions 

 of the material illuminated, 75' and "16. 



Other phenomena attendant on the transmission of the light, 76 and 77. 



Modification of Rev. George Jones' hypothesis of a nebulous terrestrial ring. The material in 

 form, a girdle, 78. 



How the girdle is maintained. Its time of revolution around the Earth tlie same Vfith that of the 

 Moon, 79. 



Oval form of the girdle, and certain conditions of equilibrium, 80. 



Girdle, in equilibrio, retains its form when the distance of the moon varies; but its dimensions 

 change, 81. 



Dimensions of the girdle, 82. 



Tidal action of the moon on the girdle, 83. 



Other peculiarities are noticed in connexion with Consistency GOth, in 100. 



Curvature of parts of the girdle, 84, 



Five cases of variety of illumination of the girdle, and therefore of variety, etc , of the Zodiacal 

 Light to be looked for, 85. 



Variation of brightness probable, 86. 



Observations of phenomena, presented by the Zodiacal Light, and statements of the Moon's position 

 at the times of observation, 87. 



"Moon" Zodiacal Light, 88. 



Various additional observations, including those of the "pulsations" of the Zodiacal Light, 89 to 93. 



Absence of parallax of the Zodiacal Light accounted for, 94. 



Summary of what seem to be eight special coincidences of phenomena with the requirements of the 

 theory, 95. 



Origin of the Girdle, 96. 



Conjecture as to the Aurora Borealis, 97. 



Analogies and differences of the Girdle and Saturn's Dusky Ring, 98. 



Close correspondence in the position of the planes of tlie planetary orbits in ancient times. Conjec- 

 ture as to the reason why the Swi's equator makes an angle with those planes, the mean value of 

 which is nearly 5°. Also as to the derivation of the great planetary masses from different half- 

 spheroids of the Sun; and which from which. Harmonious relations developed by John N. Stock- 

 well, M.A., 99. 



Greater inclination of the orbits of outer satellites to the planes of the equators of their respective 

 primaries, and especially the great inclination of the Moon's orbit to tlie plane of the equator 

 of the Earth ; and the yet greater inclination of the orbits of the satellites of Uranus to the 

 plane of the equator of their primary. Seasons assigned for these peculiarities, 100. 



77)6 Minor System, 101. 



Saturn and the Earth (the Saturn of the Minor System) compared, 102. 



Relations of great planetary masses, in the Ancient State of the Solar System. Possible order and 

 character of successive development, 104. 



Illustrations of Kirkwood's Analogy, 106. 



Failure of the formula derived from Kirkwood's Analogy in the case of Uranus. Reason for this, 



107. 

 Approximate coincidence of the result of the same formula with fact, in the case of Mars; admit- 

 ting the subsidiary hyjMthesis of half asteroid masses, 108. 

 The (so-called) " Bode's Law," 109. 



Immediately after these we have the Summation of Coincidences, 62 in number, 110. 

 Lastly, we have Supplementary Notes (A) and (B).
