No. 225. 



OCTOBER l-'th, 1S54: EVENING. 



Lat. at7A.,35 33' N.: Lon. 169 18' E. 



Sun set at 5A. 2fim. 



Stronger Light at 7h. 30m. : Difl'uee ~h. 20m. and ~/i. 4m. 

 Zenith point at 7k. 3()m. : Lat. 50 8' N. : Lon. 330 30'. 



This evening was not so favorable as the last. There was a permanent stratum of clouds near the horizon, with 

 passing cirri higher up. By watching carefully, I was able, however, between the clouds, to catch boundaries, and 

 to complete them as in the chart. The boundary of the Stronger Light cannot be fully depended on, as it is at best 

 badly marked, and requires more deliberate observation than I was able to give it, in order to be entirely reliable. 

 It is here offered as it seemed to me to be. When Jupiter was obscured by small clouds, the Diffuse, on the left of 

 the Milky Way, was very perceptible.
