538 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 269. 



DECEMBER 2th, 1854: MORHINO. 



Lat. at 4A., 13= 18' N. : Lon. 94 44' W. 



Sun rose at 6A. '23m. 



Stronger Light at 3A. Om. and 4/<. 30m. : Diffuse at 3 o'clock. 

 Son's Ion. 276 29'. 



Clouds yesterday morning. Sky this a. m., at 3 o'clock, very clear and bright ; at 4 h 30 was troubled by passing 

 clouds, but still, by careful watching, I was able to get reliable boundaries for the Stronger Light: could not succeed 

 for the Diffuse at that hour. The remarkable sliding over of the upper part of the Stronger Light, which may be 

 seen in all my recent observations, was so great this morning, that I could not be satisfied about it until after re- 

 peated trials, all bringing the same result. I believe that the boundaries on the chart may ba considered fully reli- 

 able, each new effort to trace them, by different stars, having given me the same result. The effulgent Light, very 

 strong at 4' 1 30 7 ", is marked by the zigzag lines. Dawn at 5 o'clock.
