50 OBSERVATIONS ON THE ZODIACAL LIGHT. 



No. 25. 



JULY 6th, 1853 : MORNING. 



Lat. at 2/i. 30m., 31' S' N : Lou. 134 3 31' E. 



Sun rose 5h. Cm. 

 Diffuse Light at Oh. 30m. and 2A. 30m. 



Wont on deck at half an hour after midnight, and was surprised to find the Zodiacal Light, at this early time, 



quite distinct. I asked the officer of the deck, Lieutenant M , if he could distinguish it ; and he had no difficulty in 



doing so. I could see also that the whole of that portion of the heavens enclosed between the Milky Way and the 

 horizon, 75 wide (midway across which, slantingly, the Z xliacal Light passed), was not s.i black, and that the stars 

 were not so bright, as in the portion of the sky on the other side oi't'ie Milky Way, between Corona Borealis, and 



the horizon N. of it, in which Lieutenant M also agreed with me. His answer was : ' ' Yes, now I can see it, since 



you point it out." The portion of the dimmed sky of last evening's observations, still in sight, was also as dim as 

 in the evening. 



There was a very splendid meteor this morning, just before I went on deck. It cast quite a strong light on the 

 deck.
