Double ; 10th and 12th, or 15th magnitudes. 



Passy ; January 2, 1825 ; Seven-feet Equatorial. 



Position =: 66° 30' sf; single observation. Excessively diificult. 



These stars are so very faint, that measures entitled to any confidence cannot be 



obtained.

Observed when on the meridian. Night very fine ; but the measures, particu- 

 larly those of distance, are so excessively difiicult, that I fear they must be consi- 

 dered as liable to some inaccuracy.

Measures little better than guesses. The fog is now become so dense, that to 

 persevere in observing, is impossible. 



Mean Result. 



Position 67° 30' sj (ii Obs.) ; Epoch 1825.04 ; 



Distance 22",90o+(3 Obs.); Epoch 1825.05. 



The angle, Feb. 16, 1783, was 61** 36' sf, differing 5° 34' 

 from the present, being a change of +0^.132 per annum. 

 The distance at the period above specified w^as 22".6o, agree- 

 ing very exactly with the present. Future observations must 

 decide on the reality of the motion here indicated. (H.)
