76 Mr, South' s observations of the apparent distances 



No. CCCCLXXXI. R. A. 5^ i7" ; Decl. 2** 46' N. 

 Struve, 180; I. 53. 

 Double; 8th and 12th magnitudes; small star decidedly 

 blue, and bears but a very feeble illumination. A star of 

 the 8th magnitude precedes it to the north. 



Passy : January 6, 1825 ; Seven-feet Equatorial. 



Position = 45° 28' nf 7 Obs. I DifF. = 6° i' ) Excessively difficult 

 Distance = f.099 5 Obs. J Diff. = 0^505 § Excessively ditticult. 



Observed on the meridian. Night unusually fine. A double star of the 6th class 

 follows this to the north, but is too faint for measures of accuracy.

Observed when 35 minutes west of the meridian. The small star is decidedly 



light blue. 

 The observations of position of this double star are by no means satisfactory. 

 The two last sets agree sufficiently well, but differ to an enormous extent with the 

 first series ; yet the night of the 6th of January was remarkably favourable for de- 

 licate observations, and there is nothing prejudicial to their accuracy entered in the 

 rough Journal. I have tried to re-observe this double star during the present au- 

 tumn, but unfavourable weather has prevented me even from seeing it, as a double 

 star. Passy; October 22, 1825. 



Mean Result, 



Position 40° 29' nf(Qi Obs.); Distance 3^393 (i5 Obs.) ; 



Epoch 1825.09. 



In 1783 the position v^as 43° 24' nf, and a measure in 1 802 

 gave 44° 6' nf for the angle, so that no change of conse- 

 quence can have taken place in this star. ( H. )
