Sept. 7th. — At times I was nearly sure of one. A faint light of 10° amplitude, about nortb 

 point nearly. I saw no streamers. 



Sept. 9th. — A faint A.B., as I think, with a shade of doubt. About 9h to 9Ii 15m a very faint 

 light, like a just perceptible aurora, 



Sept. 12th. — A.B. seen by Mr. John Kockwell, near Portland, Me., 9h SOm; two arches, high- 

 est at vertex 15°;' some streamers. At Pittsfleld, Mass., Mr. S. C. Brace saw an auroral belt, 

 spanning sky from E. to W. horizon, and passing overhead, about llh. 



Sept. 16th. — I was within doors from 7h to 8h 45m. About 9h, I saw what I took to be a seg- 

 ment of an auroral arch low in the N., and only W. of N., but ten minutes after, on reaching 

 an open place, I could see nothing of it, and I waited ten minutes without seeing any more of 

 it. The N. in general seemed a very little lighter than common, but was slightly hazy. [A.B. 

 seen by Mr. Francis Bradley at lOli ISm; no streamers.] 



Sept. 18th. — At 71i 58m a few streamers W. of N. and moving W., altitude at top 20°. At 

 8h l5ra all faded, and I retired. [At lOh 30m faint light, but no streamers. (F. B.)] 



Sept. 23d.— About 9li, had some suspicions of a little unusual light, probably due to moon- 

 light. Same to lOh.
