Nov. 16th. — After lOh clear. There is apparentlj' a faint liglit in N., but I am not certain. 



Nov. 20th — I watched it occasionallj', but saw no streamers; the liuht was slronj; for lOO"* 

 of N. horizon ; arcli at one time about 10° high At 8h 10m a piece of arch whose lower edge 

 cut (3 Ursse, Majoris ; it was about 50° lonjj;, most E. of N. It was gone at 8h SOm. Zodiacal 

 light faintly discernible from junction of Galaxy and bow of Serpentarius, extending to head 

 of Capricornus ; but it is quite uncertain how far it extends. 



Nov. 23d. — I think there was a slight A.B. between 9h and ICh very low in N. 



Nov. 30th. — At lOh 35in there is a faint auroral light in N. horizon. 



Dee. 13th. — Merely a faint variable light low in N. horizon. 



Dec. 17th. — About 80° of N. horizon illumined 1° or 2° high. I saw no streamers, but did 

 not watch attentively. Zodiacal light has become quite plain T reaches indistinctly to a Arietis, 

 but 2° more southerlj'. 



Dec. 21st. — I watched at Intervals, in all 30™ or 40m. Saw only two streamers, viz. at 6h 17m 

 to Gh 37™ in Lyra. In the N. there was much diffuse light, and an arch elevated 3° to 6°, fluc- 

 tuating of course, but quite distinct; arch comprised perhaps *.)0° of horizon. 



Dea 23d. — Being occupied could not observe until 8h .55m ; at that time there was a narrow 

 sea:meut of an arch between t Draconis and Mizar, well defined and constant for 15m. — See 

 N^H. Daily Herald for Dec. 23d. 



Dec. iMth. — During most of the evening there seemed to be a fiiintly luminous v.ipor in the 

 N. particularly, but also more or less elsewhere. It could scarcely have been nebulous hazi- 

 ness. There were also singular long faintly luminous streaks, chiefly in N., but obeying no 

 usual auroral laws. I am inclined to consider the whole as an auroral affair of little intensity.
