62 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 31. 



JULY 9th, 1S53 : EVENING!. 



Lat. 35 12' N.t Lon. 139 44' E. 



Sun set 7A. 12m. 



Stronger and Diffuse Light at 9A. 15m. and 9&. 30m. 

 Zenith point, at 9A., Lat. 54 40' N. : Lon. 229. 



Moon interfered with the Zodiacal Light till 9 b 15 m , when it set. The atmosphere was remarkably clear, and the 

 Light better than several evenings previous at these hours. At 10'', atmosphere still clear, but the Zodiacal Light 

 proper was gone, except a brightish spot from 94 to 70 and 68 Leonis Majoris; but, although the elongated Zodiacal 

 Light had no longer its proper limits, it seemed now to have ascended, and widened over what I have usually called 

 the dimmed or paled sky; all of which was now filled with a whitish light, so as to be very striking.
