Fine evening for observations. Watched carefully to trace the first indications of the Zodiacal Light. The twi- 

 light contracted and faded; and then (I could not tell exactly the time), there was a changing into the Zodiacal 

 Light. I knew it to he the latter, tor the first time, at 6 1 ' 30 m ; hut as yet this was only the Stronger Light, the 

 bounds as given in the chart. Then this Stronger Light began to widen, and the Diffuse Light to edge it, and to 

 ascend pretty rapidly; and, at 6 h 45", they were as in the chart.
