51C OBSERVATIONS ON THE ZODIACAL LIGHT. 



No 273. 



JANUARY 5th, 1855 : EVENING. 



Lat. 8 47' N. : Lon. 79 31' W. 



Sun set at 5^. 51.\m. 

 Stronger Light at "A. and "lit. 5Uw. : Diffuse at 7 o'clock. 



Moon, and clouds also, since ray last, both morning and evening. This evening the western sky was clear 

 and favorable for observations. The Zodiacal Light was quite distinct at G 1 ' 50'", but did not give fully reliable 

 boundaries till 7 o'clock. At 7" 50'" there was a singular appearance within the boundaries marked for that 

 time. It was as if a thin white gauze had been drawn along the sky, quite concealing the smaller stars, and 

 yet in all other respects like the Zodiacal Light. I thought, at first, it was a thin cloud or haziness, and 

 watched to see it change; but it \va< p.-nuauent, and, except its hiding the stars, was so much more like the 

 usual Zodiacal Light, that at last I recorded it as such. The Light at 7" was very strong, with a more efful- 

 gent portion below the zigzag line. Moon rose about 8 o'clock.
