(109) 



Au^. 28th. — A decided A.B. reported by divers person?, but I was engaged within doors, and 

 did not see it. Streamers seen, but probably not very hijih. 



Aug. 3lst. — An A.B. seen about 9li ; several faint streamers for a few minutes; afterwards a 

 diffuse light only to lOh. 



Sept. 1st. — Diffuse light ; several faint streamers, some 10° high about lOh : no arch seen to lOh. 



Sept. 3d. — Vif^ible as early as 7li 15m, and as late as 41i A. M. of 4th. 



Sept. 4th.— Mr. W. C. Redfleld informs me that at Albany, N. Y., it was partly clear, and 

 there was visible a plain auroral segment for some time. He saw no streamers. 



Sept. 11th.— Tolerably good opportunity for observation. Faint A.B. suspected to lOh, but 

 uncertain. 



Sept. 13th.— Tolerably good opportunity for observation. No A.B. to llh, or possibly a faint 

 illumination. 



Sept. 14th,— About lOh a low bright band of light lying along the North. About midnight 

 more litrht, and streamers 20° high. At oh a. m. of 15th, Mr. L. A. Daggett tells me that A.B. 

 was bi'illiaut, but no higher than 30°. 



Sept. 15th.— No streamers seen to lOh, but not well watched ; a baud of strong light ; up to 

 lOh there was no light higher than about 20°. 



Sept. 16th. — Possibly a faint auroral light, but doubtful. 



Sept. 17th. — Some faint auroral light suspected, but quite doubtful. 



Sept. 19th.— A.B. seen, but slight; about 9h a few streamers 15° high about N. 20° E. Did 

 not observe for more than 15 minutes. 



Sept. 21st.— On account of clouds and moon, observation very unsatisfactory. [A decided 

 A.B. between 9h and lOh. Seen by Mr. F. Bradley.] 



Sept. 28th.— At lib an ai-ch 25° liigli, and much general light. Moon then two hours higli.
