The small star is extremely obscure, and the measures of distance are perhaps a 



little questionable.

Before the mean angle was known, the position wire was placed at Zero, and the 

 large star being bisected by it, I could not satisfy myself whether to assign the 

 small one to the north or south quadrants. The measures, particularly of distance, 

 may be liable to a slight inaccuracy, for the small star will scarcely bear any illu- 

 mination. Night fine.

The past has been a night such as rarely, very rarely occurs ; from five o'clock in 

 the afternoon till now, (four o'clock in the morning,) the stars have been unusually 

 tranquil, and most exquisitely defined. At the commencement of the observations 

 the Thermometer in the observatory stood at 31°, and it has gradually fallen to 23°.
