No. 142. 



SUN AND MOON. 



APRIL 22d, 1854: MORNING: (Monday) 

 Lat. 34 40' N. : Lon. 133 59' E. 



Sun rose 5fi. 24m. 



Sun, Diffuse 2A. 45m. : Moon, Stronger 3A. 18/n. ; Diffuse 2A. 57m. and 3A. 3m. 

 Zenith point at 3h.: Lat. 57 40' N:: Lon. 249. 



Was on deck at 2" 35 m . Morning remarkably clear, with stars, seaward, down to the horizon ; on the east, some 

 hills in the way. At that early hour the Zodiacal Light was easily distinguishable, and I got the upper boundary 

 of the Diffuse at 2" 45 m ; the lower was hidden by the hills. At 2 h 50'" the Light began to brighten at its lower 

 side, and I saw the moon had got near enough to affect it. Took the upper boundary b of this Moon Zodiacal Light 

 at 2 1 ' 5*7 ; and at 3" 3" 1 , c; at 3 1 ' 18"' there was a great brightening in a part within the boundary a; at 3 1 ' 24., the 

 moon showed itself above the hill. 



The observation was unsatisfactory, for the rnoon came so early as to prevent a good Sun Zodiacal Light, and 

 was not strong enough to give a good one from its own light ; but I give the result for what it is worth.
