278 BSERVATIONS ON THB ZODIACAL LiaHT. 





No. 139. 



APRIL 18th, 1854: EVENING. 



Lat. 34 40' N. : Lon. 138 59' E. 



Sun set Gh. 30m. 

 Stronger and Diffuse Light, 8 and 9 o'clock. 



The mornings are now very hazy, the sky covered with clouds. As the day advances, the clouds are dissipated, 

 and the haze becomes thinner; till, in the evening, the sky admits of observations, though not perfectly clear. This 

 evening, although there was a white light within the Zodiacal Light limits at aa earlier hour, I could not get 

 reliable boundaries till 8 o'clock. After 9 1 ', clouds interfered. In this haze, it was not easy to get the boundaries of 

 the Diffuse Light ; but I believe that those given in the chart may be depended on.
