OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 2. 

 APRIL 4th, 1853 (3d was Sunday) : EVENING. 



Lat. 16 54' N.: Lon. 110 36' E. 

 Sun set 6h. 10m. 



Stronger Light] ' g^" 1 ' j Diffuse, probably at 7A. 10m. 



The upper end of the Diffuse portion of the Zodiacal Light is now lost in the Milky Way ; it is also so dim now, 

 that I find great difficulty in getting its boundaries. I thought again this evening that, as time passed, the 

 Stronger Light appeared to slide bodily over toward the south. I have given its boundaries as they seemed to be at 

 the times specified in the chart.
