In the former communication | Scorpii was only observed 

 as a double star ; Sir W. Herschel however having described 

 it as triple, I have examined it several times with reference to 

 this point ; but the extreme unsteadiness of the stars, parti- 

 cularly those of low altitudes, during several weeks past, has 

 precluded the use of high magnifying powers. This even- 

 ing the stars being more tranquil, a power of 327 was applied, 

 and an elongation of the large star was at times suspected : 

 413 confirmed the suspicion, but was inadequate to separate the 

 two stars. The angles here given were obtained with 513, 

 with which the discs of the stars seemed in contact ; but their 

 extreme unsteadiness under this magnifying power rendered 

 all attempts to procure measures of distance abortive ; and the 

 position, from this circumstance, must be regarded with some 

 distrust. The stars have the same colour, and were observed 

 on the meridian. 



Passy ; June 21, 1825 ; Seven-feet Equatorial. 



Each of the 7th magnitude. 



Position = 81° 48' np ov sf\ 5 Obs. | DifF. = 6° 22'. Extremely difficult. 



Three of the angles were gotten with 512, the other two with 413. The extreme 



unsteadiness of the stars rendered the observations so unsatisfactory, that I consider 



them as little else than approximations. Observed on the meridian.
