574 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 287. 



JANUARY 23d, 1855: 



Lat. at 4k., 14 44' 8. : Lon. 78 51' W. 



Sun rose at 5/i. 51i. 

 Stronger and Diffuse Light at 2h. 30m. and 4/i. 30m.. 



Was on deck at 2" 30 ra ; sky very clear and bright. Had some difficulty in getting boundaries of the Diffuse 

 on the south, as they are not well marked. The Light was strongest of all below the zigzag x. At 4" 20"' the 

 effulgence extended only to y ; but it was very brilliant. Sky still very good for observations; but being very 

 unwell, I did not continue them further.
