re-formed. There seemed a movement in parts of the display to the N.N.E., but some patches, 

 carefully watched, remained quite stationary. One arc distinctly passed from S. to N. of zenith, 

 and, when S., its upper edge had the usual vertically fibrous fringe. Immediately overhead there 

 was a mere band of light, but to the N. the vertical fibres again sprang up. The greatest 

 brilliancy was about equal to a star of the 2nd magnitude. Temperature, - 30 F. b. Calm. 



July 23. 2h. a.m. Faint auroral streamers converging N. to E., altitude 50. Temperature, + 2 F. 

 Wind E., 1-2. 



July 24. 2h. a.m. Diffused aurora in S.E. and S. and slight trace in S.E. at 4h. a.m. 



Midnight. Very faint narrow auroral bund, extending from N.E. to S.W. through zenith. 

 No movement visible. Calm. b. Temperature, - 8 F. 



July 25. 4h. a.m. Very faint and disconnected arc of rays, extending from N. through I'], to S.\V., 

 altitude between 30' and 40. No movement visible. Wind N., 1. Temperature, +9 -2 F. 



6h. a.m. Very faint and disconnected arc of rays, extending from N. to S.E., altitude 20 to 

 30. This shortly changed into a narrow arc of diffused light, with extremely faint rays at the 

 N. end. 



From 4h. to 6m. a.m. there was a continuous aurora of the above nature, sometimes extending 

 to the S., but always faint and of the same altitude. 



8h. a.m. Very faint auroral streamers S.E. and E. 



Midnight. Faint auroral streamer in S.E. 



July 26. 2h. a.m. Faint auroral streamer in S.E. 



4h. a.m. Low arc S. to S.E., altitude of apex 20. Occasional bright rays, showing above 

 land, from S.E. to N.E., extending to an altitude of 50. Auroral curtain in N., altitude 

 30 to 70. 



6h. a.m. Low arc S. to S.S.E., streamers, or rays, through E. to N. 



8h. p.m. Diffused extensive aurora from E. to S.W., very faint. 



lOh. p.m. Aurora light just showing up above hills from N.N.W. (magnetic) to S. 15 W. 

 magnetic. 



Midnight. Aurora just above hills, from S. to S.W. magnetic, altitude about 5. 



July 27. 2h. a.m. Isolated patches of diffused aurora, from N. to S.E., true, altitude 10 to 30. 



4h. a.m. Streamers, or rays, from N. to S.E., true; various heights, mean 40. 



The aurora was more or less visible all night, and confined principally to N.E. true, average 

 altitude 20. Died entirely away at about 5h. a.m., when a very thin mist of Ci.-s. cloud 

 covered the sky, partially obscuring the light of the stars. Temperature, -24 F. to -31 F. 

 Calm. b. 



At about 9h. 45m. p.m. an unusual form of aurora appeared. A band of light extended 

 from due S. to due N., passing round through E. Breadth of band 5" and averaged 12 in 

 altitude. Intensity fairly strong in N., where a greenish tint predominated, and occasionally 

 a reddish hue manifested itself. The display reached its maximum brilliancy at about 9h. 50m. 

 p.m., and had almost entirely disappeared at lOh. 10m. p.m. A few arrow-like beams were 

 visible here and there just above the band. 



Midnight. A few faint streamers in E.S.E. true, and then a segment of a low arc appeared 

 in gap. It became bright and faded away in the space of about three minutes. 



July 28. 2h. a.m. Faint aurora diffused over the E., forming a narrow curtain and a few streamers 

 scattered irregularly. 



3h. a.m. Fine display of aurora, involving the whole heavens from N.W. by E. to S. true. 

 Nothing ever visible in S.W. Three fine compact curtains in the E., one above the other, height
