Whilst making these observations, I did not feel the slightest confidence in their 

 accuracy ; the smaller star could only be seen by glimpses, and then very indis- 

 tinctly ; indeed this double star, as well as the 53rd of the 1st class (see the fol- 

 lowing page), would be proper objects for Mr. Herschel's 20-feet reflector.

 9th and 12th magnitudes. 

 Position = 47° 23' np | 6 Obs. | Diff. = 7° 11'. Excessively difficult. 

 The night is tolerably good, but no measures of distance can be obtained. The 

 stars, at the time of observation, were 50 minutes west of the meridian. 



The discordance between the first and two subsequent series of observations of 

 position, is very considerable j it would seem to indicate an error in the measures 

 obtained on the 6th of January j against them there is however nothing in the shape 

 of memorandum, to be found in the rough journal ; on the contrary, the night of 

 January the 6th was one of uncommon fineness. I have tried to re-observe this 

 star several mornings during the present and the last months, but without success ; 

 indeed, except the weather is unusually favourable, the star, with my instruments, 

 can scarcely be recognized as double. Passy, October 22, 1825. 



Mean Result. 



Position 50° 48' np (20 Obs.) ; Epoch 1S25.08 ; 



Distance 2".982 (10 Obs.) ; Epoch 1825.05. 



The mean of four angles in 1782 and 1783 gives 51° 47' np 

 for the position of this star (Sir W. H. MSS.) A measure in 

 1802 makes it 50° 1' np " very exact." This star then is 

 liable to no change of position. (H.)
