382 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 191. 



JULY 26th, 1854: MORNING. 



Lat. at 3A., 24 24' N. : Lon. 120 4' E. 



Sun rose at ah. 2Dm. 

 Stronger Light at 2 and 3 o'clock: Diffuse at 3 o'clock. 



Was up .at l h 30, in order to see whether the Zodiacal Light was visible at that hour or not. The sky was 

 unfavorable, not being bright, and there were clouds also at the eastward. I thought the Zodiacal Light was 

 plainly distinguishable between the clouds ; but I could not get boundaries before 2 o'clock ; succeeded also at 3 h ; 

 but both at 2 and 3 o'clock, the Zodiacal Light had a very singular appearance, such as I had never noticed 

 before. The Zodiacal Light is usually a clear transparent lisjht, with a slightly yellowish tinge ; and the stars, 

 which are behind, are but slightly dimmed by it ; but, on this occasion, it looked as if it had all been muddied. 

 The stars back of it were much dimmed or quite obscured ; while, on each side, though not shining with the bril- 

 liancy frequently seen (the sky a little hazy), they were as in other parts of the sky. 1 consequently got the 

 outlines, particularly of the Stronger Light, with more ease than I commonly do. 



(P. S. 26th July, 10 h a. rn. Sky overcast and threatening since sunrise.) 



(P. S. 29th July. This was followed by a gale.)
