 Zenith puint at 3V] 5m. , Lat. 55 30' N. : Lon. 252. 



The sky, at 3 h 15 m , very favorable, except some clouds on the left, near the horizon. I observed between the 

 clouds that the effulgence which I have lately marked at a a was already there ; but I could not get its boundaries. 

 At 4 h 15 m the eastern sky was cloudy below, allowing me to see only the upper ends of the Stronger and Diffuse 

 Light : on the right, no part of the Diffuse boundaries could be made out reliably.
