This has been a wet and stormy month. The air was gene-
Jelly replete with low floating vapours, which often underwent
a rapid condensation, by means of the crossing and opposite
currents of wind : therefore, the fluctuations of the mercury in
~the barometer were frequent, there having been at least 27
.chauges—the spaces too, described by its motion, exceed those
of any other month this year. The mean temperature of the
air is tbur degrees and one-fifth higher than the mean of De-
cember for the last ten years: and this was the warmest De-
cember that we have experienced during that period, except-
, ing that month in the year 1821.
The temperature of spring water is upwards of a degree
higher than it WAS at this time last year, as we we have had no
penetrating frosts yet to keep down the heat of the ground ; and
although the autumn has been very wet, yet the prevailing
west and south-west winds have modified the winter constitu-
tion of the air to the comfort of invalids, and to the benefit of
..the poor.
The maximum temperature of the air has occurred on five
different nights this month, that is, it was warmer in those
nights than in the days . preceding them. To give an idea of
the constant humidity of the atmosphere, it is only necessary to
state that it really has rained, more or less, on 86 days since the
2d of last September, and that during that time, more than 16
inches in depth have fallen here.
.The atmospheric and meteoric phenomena that have come
within our observation this month. are one parhelion, one lunar
and two solar halos, one rainbow, four meteors, lightning and
thunder in the evening of the 2d inst., and 13 gales of wind, or
days on which they have prevailed, namely—one from the
. north, and 12 from the south-west.
