The small star to-night will bear but the slightest illumination. 



North preceding, and at about the same distance, is a star of the 1 5th magni- 

 tude ; but it is so excessively faint, that neither its angle with, or distance from A 

 can be observed ; yet the night is very clear.

The distance I cannot obtain ; the small star C will not bear the slightest illu- 

 mination. The star C is also itself double of the 5 th class ; but although the night 

 is remarkably fine, I cannot get even approximate measures of it.

The star C seen double of the 5 th class ; but its small star, which is south pre- 

 ceding, is so very obscure, that my attempts to procure measures of it have been 

 unsuccessful ; yet the night is exceedingly fine.
