No. 308. 



MARCH 2ist, 1335 : EVENING. 



Lat. 22 55' S. : Lon. 43 6' \V. 



Sun set at 6A. 7.1'. 

 Stronger Light at 8/(. 3Um. : Dill'use at 8A. 30m. and 9/i. Urn. 



The moon did not set till near S' 1 30, when I was able to get an observation : sky clear and brilliant, bnt the 

 Stronger Zodiacal Light already so much dimmed, and so little of it left, as not to give very good outlines below; the 

 upper part is also not fully reliable. The boundary of the Diffuse Light given may be relied on ; the lower one of the 

 latter could not be had. At 9", the Light was still distinct, but dim, and would give no reliable boundaries for the 

 Stronger Light. The Diffuse was the same as at 8 h 30 m .
