during the Expedition under Captain Parry . 
loured lines joined the opposite paraselene?, and formed four 
quadrants, by bisecting each other at the Centre of the circle. 
A segment of another halo, concave upwards, seemed to touch 
the highest paraselenae. All these appearances varied in bright- 
ness, and continued for more than an hour. A similar pheno- 
menon was seen on the 2d. The mean temperature of these 
two days was — 30° and — 32 J°, and the minimum tempera- 
tures — 34° and — 36°. 
Paraselenm of a similar kind were seen on the 1st January 
1820, at 11 o'clock in the forenoon, and also on the 2d. The 
mean temperature of these two days was — 18° and — 24°, and the 
minimum temperature • — 28° and —29°. A drawing of the pa- 
raselenes of January 1. is given by Captain Parry, p. 131. 
Two parhelia were seen on the 8th March, one on each side 
of the sun, and at the distance of 21 §°. The side nearest the 
sun was of a bright red colour, shading into orange and yellow. 
The mean temperature of that day was — 18°, and the minimum 
temperature — 22°. A drawing of this meteor is given by Cap- 
tain Parry in p. 156. 
Various halos and parhelia were seen in the beginning of April, 
the mean temperature varying from — - 6° to — - 20°, but on the 
9th April a remarkable one appeared, which continued from 
noon till 6 o'clock in the evening. “ It consisted of one com- 
plete halo, 45° in diameter, and segments of several other halos ; 
the most perfect of them was immediately above it, where more 
peripheries touched : the other segments were one on each side 
of the halo, not unlike parts of a rainbow, resting on the hori- 
zon ; and two above it, that is, between it and the zenith. Be- 
sides these, there was another complete ring of a pale white co- 
lour, which went right round the sky, parallel with the horizon, 
and at a distance from it equally to the sun's altitude. Where 
this ring or circle cut the halo, there were two parhelia, and 
another close to the horizon, directly under the sun ; this was 
by far the most brilliant of the parhelia, being exactly like the 
sun slightly obscured by a thin cloud at its rising or setting. I 
have always observed, when these halos or parhelia are seen, 
that there is a little snow falling, or rather small spiculas or fine 
crystals of ice." A drawing of this parhelion is given by Cap- 
tain Parry in p. 164,
