Sept. 25th. — I think there is a faint light, before 10b. 



Sept. 28th. — Mr. D. E. Sykes tells me that at Boston, Mass., two auroral arches were seen, 

 about 8h ; they were concentric, and about 20° high. Possibly this may belong to the previous, 

 •or the succeeding Thursday. 



Oct. 1st. — A faint light in the N. like the dawn at 4h a. m. (of 2d) extending up 1° or 2° ; no 

 streamers. Zod. light distinct, extending to the nebula in Cancer, and perhaps 3° beyond it. 



Oct. 6th. — Faint streamers at 6h 36m, and more at lOh 20ni. Between these dates only a 

 general diffusion of light in the N. 



Oct. 10th. — At 4h A. M. of 11th there seemed to be a very faint light in the N., but I am un- 

 certain whether there it is unusual. 



Oct. 13th. — Needle slightly disturbed, but no A.B. seen. 



Oct. 18th. — A faint A.B. low in N. horizon (mucli of the time obscured by clouds), to 8h 30m, 

 ■when moon interfered. No A.B. visible after this to lOh. 



Oct. 21st. — A diffuse fluctuating light. No streamers. Aurora seen Sunday moniing, by Dr. 

 N. B. Ives, between 3h and 4h ; numerous bright short streamers. 



Oct. 39th. — At lOh thought there was a faint N. light, but not very sure.
