May 12th. — Looking out at that time I found several streamers (one extending- up 25'^ more 

 or less) not very bright, yet distinct. I saw no bank of light and no arch. The moon was just 

 rising. I looked several times after this, but could see no auroral traces up to 9h 40m. The 

 moon might conceal them if very faint. 



May 13th. — Groups of streamers sprung up here and there, some reaching up 35° and min- 

 gled with amorphous luminous matter; rapidly shifting, and occasionally for a few minutes 

 wholly invisible. During the whole time there was scarce any general light, or arch, or bank. 

 At intervals, streamers at points distant 70^ on horizon. 



May 18th. — From 9h to lOh a faint general illumination. I saw no streamers. Mr. F. Bradley 

 saw two streamers about 9h. 



May 19th. — None seen until about 9h 30m ; from this to lOh were occasional dim broad streamers 

 reaching 6° to 10° altitude, intermingled with luminous patches ; faint and transient. No general 

 light or luminous arc. Streamers VV. of N. moved westward. Streamers E. of N. uncertain. 



June 14th. — Suspecting slightly some unusual illumination in north, I went at 9li 2Sm to canal 

 bridge, where there is a clear horizon, and saw but little at first. At 9h 30m a streamer ap- 

 peared about N. 30° W., and in one or two minutes ten or tiftecn more, occupying about 60o 

 or 70° horizontal extent. From that time to 9li 48m streamers numerous appeared and van- 

 ished, reachino; up from 10° to 30° of altitude, perpetually shifting, but direction not easily 

 determined. Saw no arch ; streamers arose from very near horizon ; but little general light. 

 At 9h48[n very little auroral illumination.
