TABLE OF CONTENTS. 



Explanation of the appearance of certain satellites of Jupiter as darh 

 spots, in their transit across the face of their primary. Significance of 

 the same as respects the rotation, temperature, atmosphere, etc., of 

 satellites ........ 



Of the Zodiacal Light — M. Laplace's proof that the Zodiacal Light is 

 not due to the sun's atmosphere ..... 



His subsidiary hypothesis as to the constitution of the material which 

 affords us the light ....... 



Eastern and Western ajipearaiices of the light have occurred simidtaneously 



Difficulty of supposing that the material is an immediate solar appendage 



The material a terrestrial appendage — its rarity .... 



The light, to a great extent, transmitted light. Observers at diverse 

 stations see different portions of the material illuminated 



Other phenomena attendant on the transmission of the light 



Modification of Rev. George Jones' hypothesis of a nehidous terrestrial 

 ring. The material in form, a girdle .... 



How the girdle is maintained. Its time of revolution around the Earth 

 the same with that of the Moon .... 



Oval form of the girdle, and certain conditions o? equilibrium 



Girdle, in equilihrio, retains its form when the distance of the moo 

 varies ; but its dimensions change .... 



Dimensions of the girdle ...... 



Tidal action of the moon on the girdle .... 



Other peculiarities are noticed in connexion with Consistency 60th, in 



Curvature of parts of the girdle .... 



Five cases of variety of illumination of the gii-dle, and therefore of variety 

 etc., of the Zodiacal Light to be looked for . 



Yariation of brightness probable .... 



Observations of phenomena, presented by the Zodiacal Light, and state 

 ments of the Moon's position at the times of observation 



"Moon" Zodiacal Light ...... 



Various additional observations, including those of the "pulsations" o 

 the Zodiacal Light ...... 



Absence of parallax of the Zodiacal Light accounted for 



Summary of what seemed to be eight special coincidences of phenomena 

 with the requirements of the theory .... 



Origin of the Girdle ...... 



Conjecture as to the Aurora Boroalis .... 



Analogies and differences of the Girdle and Saturn's Dusky Ring 



Close correspondence in the position of the planes of the planetary orbits 

 in ancient times. Conjecture as to the reason why the Sun''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 rela- 

 tions developed by John N. Stockwell, M.A. .... 



Greater inclination of the orbits of outer satellites to the planes of the 

 equators of their respective primaries, and especially the great inclina- 

 tion of the Moon's orbit to the 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. Reasons assigned for these 

 peculiarities ........
