Sun set at 6h. 26m. 

 Stronger Light at 8A. 45ni. and 9A. 15m. : Diffuse at Sh. 45m. 



Clouds last evening and this morning. Moon did not set, this evening, till 8 h 45, when the night became very 

 favorable, being clear and bright. The effulgent portion, as bounded by the zigzag, was still worthy of note ; 

 and, at 9 o'clock, though greatly dimmed, it could be distinguished from the other portions. At 10 1 ' the Zodiacal 

 Light still continued ; the boundaries apparently as at 9' 1 15'". It was now, however, very faint.
