Lat. at 3A. 30m., 28 50' N. : Lnn. 116 43' \V. 



Sun rose 6/. 54m. 



Stronger and Diffuse Light, 3A. 30m. 

 Sun's Ion. 268 20'. 



Worn out by the watchings of the previous nights, I did not have myself waked this a. m. till 3 1 ' 30 m , when I 

 found the sky not favorable for observations ; but I was able to get outlines, as in the chart. Clouds prevented my 

 getting the lower boundary of the Diffuse Light. 



At 5 1 ' was out again, but the sky was now so dimmed by clouds that I could get no reliable boundaries.
