Was up at 2 o'clock, and found the Zodiacal Light very distinct. Got boundaries easily, except for the Diffuse 

 Light, which was dim at its outer edge. At 3 h , clouds ; but sky quite clear and bright from that to dawn. 

 Watched carefully through all the time to see if there were pulsations. Could not be certain, but rather think there 

 were. The difficulty in deciding is now increased by the brilliancy of Venus, and by the Milky Way, which crosse? 

 the Zodiacal Light towards its lower end. Have only the space about the Pleiades for observing pulsations : but 

 the width of the Zodiacal Light at that point seems to vary so often and rapidly, as to be accounted for only by 

 pulsations.
