Sun set at jh. 27m. 



Observations at 9/i. and 9A. 5m. 



Zenith point at 9 o'clock, Lat. 20 b' N. : Lon. 356 30'. 



At 8 h 47 m the eastern sky began to show a speck of illumination. This gradually increased, keeping within the 

 bounds of the sun's Zodiacal Light. Took its boundaries at 9' 1 and at 9 h 5 m , as in the chart, its northern end below 

 Capella being hidden by clouds, which came gliding along, and prevented further reliable observations. At 9 h 6 

 there .was a very strong light, the star ft Tauri being about its centre. At 9 h 10"' the Light suddenly broke bounds 

 as before, and spread laterally and upward. Could not tell exactly when the moon rose, the island of Cumsingmoon 

 being in the way.
