638 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 319. 



APRIL J 3th, 1855: ETENINO, 



Lat. at Sh., 20 9' N. : Lon. 53 19' W. 



Sun set at 6A. IS^m. 

 Stronger and Diffuse Light at 7h. 30m., Sh. 30m., and 9A. 30m. 



In getting the lower part of the boundaries, this evening, I was somewhat troubled by clouds ; but the sky above 

 was clear and bright, and the lines given for that part of the Light are quite reliable. At 9" 30 m the Zodiacal Light 

 was still marked on the sky, but was quite dim. The sky at that time was very favorable.
