The extreme obscurity of the small star precludes M. Gambart getting any 



observations of distance. 



The measures deemed by all observers, excessively difficult; night tolerably 



favourable, yet a higher power than 181 cannot be employed. 



The discordance between the position of this double star, 

 as determined on different nights, is enormous ; a circum- 

 stance much to be regretted, as it appears to have under- 

 gone a considerable change since Sir W. Herschel's ob- 

 servations. 



Mean Result. 

 Position 57° 9' nf ( 36 Obs.) ; Distance 2".449 ( 3o Obs.) ; 



Epoch 1825.66. 



The angle of 1783.73 v^as 46° 24' nf. Hence it appears 

 that in the interval of 41 93 years no less an arc than — 10° 45' 

 has been described, giving a mean annual angular motion of 

 — 0^.2564. This star then w^ell merits the attention of future 

 observers. (H.)

The small star bears but a very feeble illumination. Measures must not be consi- 

 dered standard : the night is become very bad. Observed on the meridian.
