noticed as the completion of the verification of Kepler's predic- 

 tion to Galileo, and attention was called to the extraordinary 

 nature of the orhits of these two moons. 



The explanation of Bode's, or rather Titius' law led naturally 

 to a description of the search for the missing planet, and to the 

 history of the discovery of the Planetoids, from the first found 

 by Piazzi at Palermo, to the two-hundred-and-fifty-third added 

 by the indefatigable Palisa. Formerly there were only seven 

 known planets, now more than seven are yearly added to the 

 list. The distribution of the orbits of the Planetoids, and some 

 of the effects of their minute size, were briefly enumerated, 

 before the orbit of Jupiter was mentioned in connexion with 

 Eoemer's discovery of the velocity of light. 



This suggested a remark on the distance of the fixed stars, as 

 this distance is estimated in terms of the time required for their 

 light to reach us ; for if all the stars could be annihilated at this 

 moment, we should remain unaware of the fact, in the case of 

 most of them, during our whole life, continuing to measure their 

 relative positions with as much exactness as if they were still in 

 existence. 



The known changes on the surface of Jupiter were then illus- 

 trated by the drawings of Delarue and Nissten, and by Denning's 

 sketches of the great red spot ; and this was followed by an ex- 

 planation of the phenomena of Jupiter's satellites. The phases 

 of Saturn's rings, their divisions and changes, so admirably 

 drawn by Delarue, Trouvelot, and others, were next described ; 

 and after a few words about the eight moons, also predicted by 

 Kepler, a detailed account was given of the discovery of Uranus 

 by Sir W. Herschel, and of Neptune by Adams and Le Verrier. 

 Lassel's additions to the worlds of the three outer planets were 

 not fox'gotteu, and the lecture was brought to a close by a des- 

 cription of the search, as yet unsuccessful, for the ultra-Neptunian 

 planet.
