Stars very steady, but the small one will bear no illumination. Observed on the 

 meridian; the distance, I fear, may be liable to an error of two or three seconds. 

 Night fine.

There appears to have taken place a change of no less 

 than + 5° 21' in the angle of position of this star since 1782, 

 which for a star of the 5th class is considerable ; unless 

 indeed from the extreme minuteness of the small star, errors 

 of observation to a larger amount than usual be supposed. (H.)
