Remarks . 
3d. — The morning was very stormy. Wind N. very strong. Heavy rain. 
Barometer 28.670. Temp. 43°. Mean pressure of the day 28.942. In the 
evening it cleared, and the stars shone brightly. An aurora was seen at 
11 o’clock. 
4 th — Pressure increasing rapidly. Mean temp, of preceding night 38°. 
Wind NW. ; pleasant day. Another aurora of great beauty appeared in the 
evening : the rays were very numerous and vivid, but they remained visible 
only for a few minutes. The phenomenon was neither preceded nor followed 
by the diffuse illumination of the northern sky which is generally seen along 
with this meteor. 
6th . — Very stormy. Pressure 28.80, increasing. Wind W. boisterous. 
7^."— Wind moderate. Mean temp. 36°. Mean pressure 29.04. An au- 
rora at 9 p. m. ; very bright. 
Mi . — Between 10 and 1 1 a. m. there appeared a solar halo, formed in fleecy 
cirro-strati. It was simple, without colour, and had a diameter of 44°, The 
pressure again diminished towards night, and much rain fell. 
1 2th . — Very pleasant day. Wind SW. gentle. Mean temp. 34°. At 
noon, the thermometer, covered with black wool, rose in the sun’s rays to 65°. 
14th At 8 p. m. when the sky was perfectly serene, a large meteor was 
seen to pass from E. to W. through a space in the heavens equal to 25°, ex- 
ploding like a rocket nearly in our zenith : it left a very bright luminous tail 
in its course, which remained visible for nearly two minutes after the meteor 
itself had disappeared. Wind W. strong. Barometer 30.07, rising. 
1 8th . — This evening, the wind blew from SW. with the violence of a hur- 
ricane, for about two hours. Barometer 29.00. 
22 d . — Last night, a meteor, similar to that observed on the 14th, was 
seen far to the south, moving from E. to W. with great velocity, and leaving 
a luminous tail behind ; and this evening, about 9 o’clock, another was obser- 
ved, moving towards the north. The apparent magnitude of these was double 
that of stars of the first magnitude. To-night, also, for about three hours, 
there was a very magnificent display of the aurora : its lustre was much im- 
paired by the light of the moon, but still it appeared more extensive, and 
played with more celerity than any that have been observed this year. The 
beams rose to the zenith, and seemed to influence very much some polarised 
cirri in the south. Temp. 37°. Bar. 30.07. 
%hth . — A lunar halo was seen to-night ; and a faint appearance of a lunar 
rainbow. Wind W. Bar. 30.02. 
26th . — Very stormy. Bar. 29.17* Wind SW. boisterous ; very heavy rains. 
28th — Ground thickly covered with snow ; during the day much rain fell. 
Wind E. boisterous. Bar. 28.83.
