No. 229. 



DUPLICATE OCTOBER Ifith, 1*54: EVENING. 



Lat. at 7/i., 33 01' N.: Lon. 174 4!)' W. 



Sun set at 5A. 21m. 

 Stronger and Diffuse Light at 7h. and 7A. 30m. 



Sky perfectly clear, and very brilliant. I noticed that at 7 1 ' 10 m the adjunct light under I b had the same warm 

 tint that the Zodiacal Light has different from horizon or Milky-Way Light. At 7 1 ' 30"', the upper line of the 

 Stronger Light had evidently tilted up considerably, as given in the chart; the lower boundary could not be made 

 out at .this time ; also the boundary b l> had become less marked than before, this latter now becoming merged in the 

 Diffuse Litrbt. At 8 h 30'" the boundaries of the Diffuse Light were about the same as a't the last observation.
