No. 266. 



DECEMBER 25th, 1854: MORNING.

 Sun rose at 6*. 32m.

 Sun's Ion. 273 26'. 



Cloudy the last two mornings. I was on deck at 12 o'clock to-niglit, but was baffled by passing clouds till 12" 

 3CP. The sky then was free from clouds, but was not at its brightest ; yet I thought there could be no doubt of the 

 Zodiacal Light, at that hour, at both western and eastern horizons. The western gave roe boundaries more easily 

 than the eastern, where I had some difficulty in getting them satisfactorily. At 3" the sky was brilliant, and the 

 Zodiacal Light very bright ; but there was the same difficulty, as on the 22d, iu getting boundaries of the Stronger 

 Light, and from the same cause. At 4 h 30'" the Light was remarkably strong ; strongest within the zigzag lines. 

 Dawn towards 5 o'clock.
