Lat. 3- v.' N. : Lon. 122 ?' W. 



Sun rose at 6//. 58m. 

 Stronger and Diffuse Light at 4/i. 15m. and 5/f.-15m. 



(Yesterday was Sunday.) The sky, at this place [Benicia, California], is perfect ; a clear deep Hue during the 

 day, and stars brilliant at night. The Zodiacal Light, at 4" 15', was not bright, but had its outlines very well 

 defined. At 5" 15 ra , very bright. At that hour I could not get the upper limit of the Diffuse Light, which was also 

 not very distinct at 4 h 15 m . I looked to see whether there were pulsations at 5" 15 ra , the circumstances being so favor- 

 able for observing them, if there wore any ; but none could be perceived.
