3J4 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 157. 



MAY 22d, 1854 (21st was Sunday): MORNING. 



Lat. 41 47' N: Lon. 140 43' E. 



Sun rose 4A. 38<. 



Stronger and Diffuse Light at 2A. 30m. 

 Zenith point at 2A. 30m. : Lat. C5 n N. : Lon. 286. 



Owing to the clouds and moon, this was the first morning observation which I have been able to have in a long 

 while. The sky, on this occasion, was pretty free from the haziness with which it is now usually obscured. At 2 h 

 3CP, the Zodiacal Light was very distinct, and its boundaries were easily got, except the lower part of the Diffuse 

 Light. In getting the upper extremity of the Stronger Light, I was troubled by the great brightness of Jupiter, 

 now at that spot ; but I put it, down in the chart as it seemed to me to be. 



Moon rose at 2" 45 m .
