Sky very clear and brilliant. I was anxious to see at what time the earliest certain exhibition of Zodiacal Light 

 in the east could be made out, and looked carefully in that quarter at 10 h last evening ; but nothing of it could be 

 recognized. At 11 o'clock, went again on deck ; and now the eastern Zodiacal Light was very apparent and decided. 



Lieutenant P had charge of the deck at that hour ; and on his coming over to where I was observing, I 



directed his attention to that part of the sky, and asked him whether he could distinguish the Zodiacal Light. He 

 answered, " Oh yes, I can see it very plainly." The sky was very fine for observations. The intensity of the Light 

 about 48, 57, and 58 Tauri was at 11" 15 m equal to that of the Milky Way at 27 and 13 Persei, or anywhere 

 between Algol and 33 Persei. (For morning observations, see chart.) The Zodiacal Light at 3" and 4" is now 

 extremely brilliant ; but the several parts melt away so gradually, that it is difficult to get boundaries except at the 

 lower end.
