6G4 OHSKRV \T10NS ON THE ZODIAC A I, MORT. 



No. 282. 



JANUARY 18th, 1855: MORHINO. 



Lat. at 4A., 3 40' S. : LCD. 82 20' W. 



Sun rose at 6A. 4w. 

 Stronger Light at 3A. 45m. and 4li. 30m. : Diffuse at 4 o'clock. 



Was on deck at 3 o'clock. The Zodiacal Light was then very distinct, but I was prevented from getting 

 outlines by passing clouds till 3 h 45 m . After 4 o'clock, the sky was remarkably fine for observations, and I 

 continued making them with the greatest care. My notes are thus : " 4 h 5 m , the Zodiacal Light has just bright- 

 ened up considerably, more especially below the zigzag line w ; 4' 1 20'", now a great effulgence within the zigzag 

 x, very marked in strength and in its boundaries ; 4 h 25, the whole Zodiacal Light very bright, but the marked 

 effulgence within x still continues ; 4 h 50 m , this extreme effulgence lias now sunk to the boundary y, and is very 

 striking : its bounds well marked ; 4 h 54, the Light is spreading laterally doubtless the beginning of dawn ; 

 4 h 56"', dawn has decidedly come." 



At 4 h 20 m , noticed that the stars of the fifth magnitude, about 42 in the left foot of Ophiuchus, also 40 of same, 

 were very distinct, though in the middle of this effulgence.
