Sept. 14th. — At lOh 1,5m I suspected a very faint light of A.B. on northern horizon. 



Sept. 18th. — Mr. F. Bradley informs me that he saw a slight A.B. at llh, a few streamers 10<» 

 or 1.5° high. 



Sept. 25th.— A brilliant arch from W.N. "W. to E.N.E. rising at 8h (the highest) about 40o ; 

 then broke up and lower arches succeeded. Between 9h and lOh, brilliant streamers and spots ; 

 none seen higher than 45°. 



Sept. 26th. — A single wisp of auroral light in N.W. just under the handle of the dipper (in 

 Ursa Mi\ior), drifted slowly westward and downward, and disappeared at 7h lom. Scarcely any 

 other auroral indications. Moon brilliant. (Short notice of A.B. of 25th and 26th published 

 in N. H. Daily ILrald and N. H. Daily Palladium of Sept. 29th.) 



Oct. 6th. — Iiiuncdiaicly after close of twilight I searched for zodiacal light; sky very clear. 

 On critical examhuition and comparison it appears to me that there is a very faint illumination 

 extending from about Arcturus in N.W. to Galaxy in S.S.W., and reaching upwards to a line 

 connecting £, a, and 6 Serpentis. No A.B. at the time. Moon and Venus interfere in the 

 morning.
