640 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 320. 



APRIL 14th, 1855: MORNING. 



Lat. at 4ft., 20 59' N. : Lon. 54 V W. 



Sun rose at 5ft. 46m. 

 Stronger Light at 3ft. 30m. and 4ft. 15m. : Diffuse at 3ft. 20m. 



The atmosphere not very favorable, and clouds on the right ; still I was able to get reliable boundaries, except for 

 the Diffuse on the right, where I could not make them out. The Stronger Light seemed to brighten up about 4' 1 15, 

 as in pulsations ; but of this I could not be certain. The moon, together with an early dawn, put an end to 

 operations.
