678 OBSERVATIONS ON THE ZODIACAL LI6H7. 



MOON ZODIACAL LIGHT, 



JULY 14th, 1854. 



Lat. 25 9' N. : Lon. 121 46' E. 



Sun set at 6A. 4em. 

 Stronger Light at 10A. 20m. : Diffuse at lOh, 16m. and If ft. Wm, 



I watched, last evening, for a moon Zodiacal Light, tut streaks of clouds in the east prevented any reliable rosults. 

 This evening the sky was very favorable, and the Zodiacal Light was strongly marked ; and was the more striking, 

 because the ecliptic made a very low angle with the horizon. Took boundaries as at 10 h 16 m and 10 h 19 m : and at 10* 

 20 m the Light was so strong below, that I also took boundaries for a Stronger Light, as in the full line in the chart. 

 Soon after this, the light spread suddenly on the right band, so as to stretch out like that on the left caused, 

 probably, by the moon's rays having now reached our atmosphere. This rapid stretching out on the right was very 

 striking.
