Oct. 20th. — Amplitude 100°, more or less. Sundry streamers at about 7h 30m, some 20° to] 

 30° high ; reddish in N.N.W., toward the horizon white light, bright. On the whole a fine dis- 

 play on a small scale. 



Oct. 23d. — In general a low twilight illumination with few streamers. [Reported to me by| 

 Professor D. Olmsted. I did not see it.] 



Oct. 28th. — Later than this the sky was partly clear, and a display of the A.B. was seen, at in-| 

 tervals, until dawn. Numerous streamers and undulations ; no corona seen.
