Twelfth Month.—23. A thaw, p.m. witha little rain: windy night. 24, Dew 
and Cirrostratus, a.m.: cloudy at intervals: windy at S.W., yet it froze in the 
evening. 26. Maximum of temp, at nine, a.m., and beginning to rain: much 
wind, especially about sun-set. 27. It is said to have lightened much, early this

snow: sleet: rain. 29. Temp. at maximem at nine: a little rain: a gale through 
the night. 30. Fine morning, though witha pale sky: Cirrostratus, coloured at 
sun-set: the river (Lea) rose higher, apparently by the tide, than at any time 
since 1809. 31. Hoar frost: a frozen mist, with Cirrostratus above, followed 
by a fine day. 
1816. First Month.—1. Misty air: Cirrostratus. 2, Hoar frost: a frozen 
mist, depositing much rime; the middle of the day fine. 3. Fine morning: the 
roads icy, it having thawed some part of the night. 4. Hoar frost: Cirrostratus 
in flocks: a breeze. 5, Coloured sun-rise: fine, with Cirrostraius.. 6. Max. 
temp. at nine: cloudy: the wind rising: very heavy Cumulostrati, after some 
rain: clear windy night. 7. Min. of temp, at nine: elevated Cirrostratus in bars, 
just visible: wind and clouds: a lunar halo. 8. Max, temp. at nine: wet morning, 
10. Much cloud, with Nimdi forming, p.m.: stormy night, 11. A gale throngh 
the day and night: much evaporation evident in consequence: lunarhalo, 12, Ci 
rostratus descending from aboye: a gale, withrain after. 13, Fairday. 14, After 
frost in the night, a shower early; drizzling, p.m. 15. Overcast with Cirro- 
stratus: rain; clear at night. 16. A slight ground frost: large Cumuli, mixed 
with other modifications, p.m. which going off, showed elevated in the N. and 
N. E.: to these succeeded linear Cirri, filling the sky, aud crossing each other 
almost at right angles: these appearances were followed by a most vioient storm 
of wind and rain in the-night, 17. Fair: wind at night. 18. Min. temp. at 
nine: hoar frost: misty horizon: Cirrocumulus, followed by denser clouds, and 
rain at evening. 19, Max. temp. at nine: very misty: at neon a bank of dense 
clouds of various modifications in the S,; windy at evening: rain in the night, 
20. Fair day.

So decided a westerly current has prevailed during this period, that on one 
night only an easterly wind was rather inferred from circumstances than observed. 
From the facility with which such a current veers to N. and S, it often makesa 
very unsteady barometer, as has happened in this case, the changes in its direction 
- having in the whole been nearly equal in number to the days of the period. In 
the fore part, a double depression was succeeded by a very considerable double 
elevation, the maximum concurring with a remarkably high spring tide, In the 
latter part the quicksilver took a range below the mean, and went rapidly through 
a series of sharp depressions, to the number of seven or eight. (The terms eleva- 
tion and depression are here applied to the whole time taken by the curve in 
receding from, and returning to, the mean elevation.) The weather has been 
such as to agree very well with the indications of the instruments: a few days 
fair, while the barometer was high: the remainder an alternation of gales of wind, 
rain, and frost: the diurnal temperature at times more under the dominion of the 
winds than of the sun.
