July 18th. — Nathaniel R. Clark, Esq., informs me that at Saratoga, N. Y., he saw between 

 9h and lOh an A.B. in the west : perhaps it is a mistake. 



July 25th. — A moderate display observed from 9h to lOh, and going on at lOh. A horizontal 

 extent of about 80° illumined; groups of streamers shot up here and there, soon fading; not 

 Tery brilliant : reaching at the highest about 25° or 30°. Some of the streamers moved west- 

 wardly.
