64 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 32. 



JULY 9th, 1853 : EVENING. 



Lat. 35 12' N.: Lon. 139 44' E. 



Sun set 7A. 12m. 

 Zodiacal Light in the East at 9A. 30m. and 10 o'clock. 



At 9 h 30 m , I turned to the eastern sky, and thought that I could make out a strip of brightness with boundaries as 

 in the chart. At 10 h , this brightness was more striking; and I could have no suspicion, in this case, as on a former 

 occasion (see No. 27), that it was an accidental brightness of the horizon: for there was now a dark haze between 

 its lower part and the horizon. Still I had some doubts of its being the true Zodiacal Light. At 10 11 45 m it was so 

 strong as very much to dissipate doubt. I could scarcely resist the full conviction that it was the real Zodiacal 

 Light. 



[P. S., 1856. See No 42, for another observation of this kind, and for remarks.]
