 Sun set at 5/i. 40m. 



Observations aU 9 40

* * * * At the proper time I turned towards the east to make observations, fearful, however, that some clouds 

 that came hurrying on would interfere. The evening, in other respects, was very favorable ; the large stars showing 

 themselves distinctly, immediately after being lifted above the horizon. At 9 h 37 m , the Light being then quite strong, 

 I got the boundaries marked a ; at 9 b 39"' b ; the Light then being very bright. At 9' 1 40' the boundaries were at c, 

 and the Light was then as bright as the sun's Zodiacal Light ever is. Clouds then slid over, and I could no longer 

 get reliable outlines ; but the Light, as seen between the clouds, still remained very strong. At 9 1 ' 46" 1 the Light 

 broke bounds and spread ; and, at 9 h 52', the disc of the moon began to appear.
