Aug. 1st. — A very faint light in N. from Ursa Major to Perseus, about 5° altitude, which I 

 suppose ma}' be zodiacal. 



Aug. 23cl.— No A.B. to lOh 30in, xinle.ss a luminous stripe which I saw at lOli 10m was auroral. 

 It was a dim belt extending from E. to W., not seen lower than about 40° on E. and 30° on VV., its 

 loAver edge near P and 7 Draconis and f Cassiopeiae. No auroral appearance in N. By lOh 20m 

 the belt was almost extinct. I am on the whole inclined to think it may have been a cloud. 



Sept. 2d. — Mr. F. Bradley saw several auroral streamers ; about 8h 30m also slight auroral 

 bank about 4° high.
