25th, - 5.30 The luminosity near the horizon from N..W. through 

 E. to S. became stronger. In the direction of 

 Mount Erebus this extended to a height of 25° up. 

 An indistinct curtain appeared in the upper part 

 of this luminous belt. There was also a trace of true 

 aurora in the luminous S.E. horizon. 



5.45 Conditions the same, though absence of any trace of 

 curtain. 



6.00 Faint trace of a curtain to the N.E. above the 

 luminous horizon. Also a faint higfh streamer 

 descending on to the summit of Mount Erebus. 



6.15 Conditions similar, but absence of distinct aurora. 



6.30 The upper portion of the luminous haze over the Ross 

 Island highlands glowed at intervals developing a 

 faint curtain. After each rekindling the brilliance 

 of the individual streamers was leavened till the 

 whole assumed an even nebulous appearance. One 

 long streamer appeared 45° up to the S.E. 



6.45 The curtain just referred to was now bright, and pre- 

 served the same trend. Three or four streamers 

 at intervals dropped to a low altitude below the 

 lower border of the curtain. 



7.00 The curtain was present but fainter. A smaller and 

 fainter one appeared 25° up in the W.N.W. sky, 

 apparently trending .W.S.W. 



7.15 The original W.N.W. trending curtain still faintly 

 visible. 



7.30 The same curtain persisted, though now only a faint 

 nebulous band, trending S. of W. Also a small 

 display to the W.N.W., as at 7.00. 



7.45 A well-defined semi-nebulous curtain stretched from 

 near the horizon to the zenith, trending N. and 

 S. As seen from below, the planes of luminescence 

 were distinctly warped in the vertical. Several 

 ill-defined streamers appeared in the E. sky. 



8.00 The remains of a curtain appeared to the N.W. ; 

 also a trace near the zenith. There was a glow on 

 the S. horizon. Daylight began to appear on 

 the N. flank of Mount Erebus, and seemed to be in 

 conjunction with a nebulous auroral display, which, 

 however, was rendered indistinct by the former. 



8.15 A curtain which crossed the zenith somewhat bowed 

 to the W., and trending N. and S. Abundance of 

 ill-defined streamers appeared to the E. of the 

 zenith. A streamer visible 35° up to the S.E. 

 • 8.30 Streamers of the above curtain still visible. Also 

 streamers seen to the S.E. 



9.00 Streamers in the S.E. still. The daylight iioav suffi- 

 ciently strong to obliterate all weak auroral effects 

 in the N.E. 



9.35 No aurora visible. Daylight sufficient to obscure 

 delicate effects. 

 10.25 A brilliant double curtain aurora stretched across the 



whole sky from the S. to the N.N.W. 

 11.00 The curtain still persisted, stretching across the 

 whole sky. From the W. of its southern end a 

 smaller curtain extended upwards from 12° to 15° 

 above the horizon for about 28° of arc as far as a
