523 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 264. 



DECEMBER 22d, 1854 : MORNINO. 



Lat. at 4.,23 16' N. : Lon. 112 30' W. 



Sun rose at 6A. 41m. 

 Stronger and Diffuse Light at 3A. 30m. and 5A. 



Clouds prevented observations last evening. The morning sky was very clear and brilliant, and I had good 

 observations. But the Diffuse Light is now so strong, and the Stronger Light melts so gradually into it, that it is 

 very difficult to get boundaries for the latter. At the first observation this a. m., I spent half an hour in verifying 

 my boundaries; and I believe those given may be relied on. Both then and at 5" I was particularly careful in my 

 observations. At 5" the effulgent Light within the zigzag lines was very brilliant. Watched to see whether there 

 were |nil^iti.>iis, but could not discover any. Could not get the upper end of Diffuse Light.
