The proximity of the star B to A, and neither of them bearing a good illumina- 
tion, or a high magnifying power to separate them considerably from each other, 
render the observations of distance of the two stars A C difficult. (The star C is 
to the south of A.) Night pretty fine.

Excessively difficult. 
Observed with 92: with a higher power I could not distinguish the small star, 
even under the most feeble illumination. The night is fine ; but the measures are 
attended with such extreme difficulty, that those of distance are perhaps liable to a 
little inaccuracy.
