NOVEMBER 22d, 1854: ETENING. 



Lat. 37 48' N. : Lun. 122 21' W. 



Sun set at 4h. 40wi. 

 Stronger and Difif.ise Light at 6A. 50m. 



Heavy fog last evening. The moon, this evening, did not set till about 6' 50'", when I was able to have a tolerably 

 satisfactory observation. A fog then rising rapidly, anil ob.scuring the western sky, was somewhat of a diawback, 

 inasmuch as I had to take the outlines hurriedly before it reached us ; but I believe they may be relied on. The 

 fog prevented any thing further through the night.
