Observed on the meridian with 413 ; stars perfectly round : a black division be- 

 tween them seen distinctly. The measures 1 consider good, and were gotten with 

 less difficulty than either of the preceding sets. Evening very favourable ; stars 

 unusually steady.

 Position r: 82° 57' sf\ 7 Obs. [ DifF. = 3<^ lo'. Extremely difficult. 



Observed when a few minutes east of the meridian with 413 ; stars at times well 

 defined : light clouds and extreme unsteadiness, render it impossible for me to 

 procure measures of distance, nor can any observations of A, or B, with the more 

 distant star C, be obtained.
