 MOON ZODIACAL LIGHT. 



SEPTEMBER 12th, 1854. 



Lat. 22 14' N. : Lon. 1 15 18' E. 



Sun set at 6^.2im. 

 Stronger Light at 9!i. 44m. : Diffuse at 9/i, 42m. and 9A. 44m. 



****** As the sky was so favorable for observations, I intended to watch for a moon Zodiacal Light, 

 though the rnoon was not at its best time, being several nights after the full ; but I was not on deck soon enough for 

 its first show of light. However, I succeeded very well, as may be seen from the chart. The fuff line gives the 

 boundary of a Stronger Light, which began to show itself about 9" 44 ra . At 9" 45A m the Light broke bounds on the 

 right, and, soon after, on the left ; but there seemed to be, from this time on, for a while, a streak of paled sky along 

 the ecliptic, running far up into the sky. I was not sufficiently certain about it, to warrant my putting it down on 

 the chart ; and it was over too soon for my getting other judgment than my own to bear on it. At 9 h 50" 1 the edge 

 of the moon appeared above the line of the smooth horizon.
