OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 4. 



APRIL 6th, 1853 : MORNING. 



Lat 21 22' N.: Lon. 112^ 57' E. 



Sun rose 5h. 52m. 

 Diffuse Light at i o'clock. 



Rose early. The Zodiacal Light already to be seen at 3 h 10 m , but was near the horizon. At 4 h , it was high 

 enough to give a distinct outline; but I was baffled by numerous flitting cirri, and could not get boundaries of the 

 Stronger Light. That given, I believe may be fully depended on.
