the 18th, I was awaked at 4 o’clock by a light shining into my cham- 
ber, which opens to the northwest. On looking out at the window, 
saw a dense smoky cioud in the west, waves from the north very 
grand, all flashing towards the pole of the dipping. needle. Examined 
the southern sky and found an ill-fermed corona around the magnetic 
pole—arches in the north ragged and serpentine—vapor milky with a 
~ slight tinge of red. At 4h. 80m.; dark segment in the north 15° high, 
but gradually sank, and about day-break (Sh. 30m .) it reached the hori- 
zon. Undulations faintly visible in the north as Jute as 5h. 50m 
shvoting stars seen. In the aflernoon, sky very clear at aurinet malt 
keen at 19° Fah., traces of aurera:in the north before the end of twi- 
light. At 8h. 12m., dusky segment in the north, with. very bright but 
transient streamers, shooting up from very near the horizon across the 
dark segment. 
Grand display of the 19th. —AtTh. dark segment skirting the north-

11h. 830m. Flashes all round the corona. Very magnificent. On

wind in a gale.

vast conflagration. — Th he segment gradually subsided, until day- break, 
when streamers continued to shoot up from the line of the horizon.
