 that Captain Beaufort cannot obtain any observations.

Epoch 1825.74. 



Sir W. Herschel's observations of this star (if II. 94) are 

 as follows : 



1783.66, Position S4° 24' np; 1802.5, 35° 6^ np. 

 These compared with the present, present a great disagree- 

 ment. If we take the mean of the two earlier observations 

 we get S5° 10' np, and 1 793-1 for a mean epoch, which 

 compared with the measures of 1825 give an arc of 6° 42', 

 described in an interval of 33 years, or about + o°.203 per 

 annum. The data, it is true, are precarious, but the conclu- 

 sion is such as to render it worth while to watch this star in 

 future. (H.) 



* This star was found by sweeping in the neighbourhood of the 784th star of 

 Struve's Catalogue. The star however whose place is there given, was only seen 

 as a single star : it is therefore very probable that the one here measured is Sir 

 W. Herschel's star.
