ASTRONOMY* 



Blackheath, Oct. 14. 



SrR, — When I computed the ephemeris of Vesta, which 

 I sent to you last month, I had not at that time reduced 

 any of my late observations; and I calculated the place of 

 the planet, irom the elements obtained} near the former 

 opposition. On reducing those of the present year, I found 

 a considerable change m the place of the node, which affect- 

 ed the latitude, and of course the declination. The quantity 

 of this change I cannot at present ascertain ; but having 

 again computed the ephemeris, which agrees with the late 

 observations; and also laid down in the chart, all the stars 

 to the seventh magnitude which are" near the path of the 

 planet, (very few of which are contained in any catalogue,) 

 the place of the object may be very readily found, by those 

 who have instruments on an equatorial stand. 



I remain your obedient servant, 



To Mr. Tilloch. S. GnooMErtiDGK, 



Ephemeris of Vesta at Midnight.

Comet. — A comet has for some time been visible 10 the 

 naked eye. It is at present in the girdle of the constellation 

 Andromeda, which is distinguished by three stars forming 

 a curve; the brightest is of the second magnitude, called 

 Mirjchy'the other two of the third magnitude,- if an ima-
