Aug. 2cl. — Groups of short streamers rising from a dark segment, some quite vivid and quick- 

 moving laterally. None reached higher than 20°. Watched about 15 minutes ; but it soon 

 faded. Moon greatly interferes. Streamers 30° each side of N. 



Aug. 6th. — There was much diffuse light in N., but obstructed by clouds, and about 9h an 

 auroral band, rising in E. and extending about 40° high at vertex, towards the west : Avas not 

 sharply defined : moved upward, but disappeared before it reached zenith. Clouds greatly 

 interfere. 



Aug. 14th. — At times a tolerably distinct arch 5° to 8° high at vertex, and occasionally a few 

 faint streamers. 



Aug. 23d. — About lOh 20m there was a decided auroral light low in N., but partially obscured 

 by clouds. 



Sept. 7th. — At 91i went to Observatory to see if zodiacal light could be discovered. I am 

 doubtful whether any traces can be seen ; there seems to be a very faint light lying a few de- 

 grees above horizon from N. to W.N.W. Nothing visible in the ecliptic, which now cuts the 

 horizon at a very small angle here.
