The principal meteorological phenomena seen during the pro- 
gress of the expedition, were Aurora: Boreales> Paraselence and 
Halos. 
1. Aurorae Borealcs and Columns of Light. — The Aurora 
Borealis seems to have been observed much less frequently 
than might have been expected. On the afternoon of the 25th 
October 1819, Mr Fisher observed at Winter Harbour two ver- 
tical columns of prismatic colours, about 15° on each side of the 
sun, (which was below the horizon.) They were about 5° long, 
and their lower end touched the horizon. They preserved the 
same intensity of colour for about an hour, (from noon to about 
one o'clock), and then began to vanish, which they did entirely in 
less than an hour. On the 29th October, Mr Fisher again re- 
marks, that columns of prismatic colours, similar to those above 
described, were observed two or three times since the 25th, at 
the same distance from the sun, and at the same altitude. The 
aurora borealis, he adds, was seen also two nights ago to the 
southward , but it was very faint. 
On the 17th November 1819, at 3 P.M. a very remark- 
able cloud of a light-brown colour was observed, the centre 
of it bearing SW. by S. It diverged from a centre at the 
horizon in straight lines or columns, which extended to a 
great distance over the surface of the sky, The lower edge
