304 OBSERVATIONS ON THE ZODIACAL LIGUT. 



No. 152. 



MAY 15th, 1854 : EVF.SIN... 



Lat. at 8 o'clock, 40 13' N. : Urn. 142 52' E. 

 Sun set 7/j. '3m. 



Strimger Light ' j'"' Diffuse Sk. 45m. and 9*. 15m. 



Clouds uniformly since the 8th, except last evening (Sunday). This evening the sky was cloudless ; hut there 

 is now, clay and night, a haziness in the atmosphere ; and this interfered a little this evening ; but still I was ahle 

 to have a good observation. The Zodiacal Light began to show itself decidedly at 8 1 ' 27 m ; but I was not ahle to get 

 boundaries till 8'' 40"'. Those of the Stronger Light would probably have extended up higher if the haziness had 

 not existed. For the same reason, I did not care about watching closely for pulsations. After 9'' SO" 1 , I was too 

 much engaged in looking for a Moon Zodiacal Light to take further boundaries in the west.
