April 6th. — Between 3li 2im and 41i a. m. of 7th, A.B., much obscured by clouds, but certain. 

 Several imperfect streamers and bright spots, none over 5° high. Being occupied with the 

 comet (Bond's) near Cassiopeia, I could not give much attention to the A.B. 



April r2th. — I strongly suspected the presence of an A.B., and at times could scarcely doubt 

 it ; this was from 8h 30m to 9h 30m. The sky remained overcast up to 9h 30ra at least. The ap- 

 pearances may possibly have been caused by the moon, but probably not. 



April 1.5th.— Several streamers 1° or 2° high, and general light after, 3* to 5° high to llh. 

 Did not watch especially, being occupied with Biela's comet. 



April 16th.— Between 8h and 9h a double arch about 5° and 3° high, and 70° to 80° span; and 

 about lOh numerous streamers, some 20° to 30° long. 



May 3d.— No A.B. certainly seen to Qh ISm, yet suspected.
