Had a fine evening for observing the Zodiacal Light. At 9 h , it was very faint, but seerned to have the same limits 

 as at 8 h 45. At 9 h 15, nothing could be made out. Last evening I drew lines as in the chart at 8 h 45 m ; but, con- 

 cluding that they could not be fully trusted, I did not copy them into my MS. This evening, without being on the 

 lookout for such appearances, I was struck with the same thing, at that time namely, a great change in the direc- 

 tion of the Zodiacal Light, and I have recorded it in the chart (see 8 h 45 m ). This is doubtless owing to the great 

 change in the angle which the ecliptic makes with the horizon, as the night advances.
