TO TEI IDITOR OP TDB DAILT DIM.

Stit,—On reviewing the Meteorological Returns
for the month of March, as laid down on my maps, I
am struck with the absence of the usual charec..eristics
of the mouth. Instead of the greater number of the
days developing the coarse of hard winds and ga!es, I
am presented with a record of calm days such as
rarely occur at this season. Nevertheless, our object
being the truthful development of facts, I am induced
to lay my usual summary b:fore your numerous
readers, in the hope that, as one of a useful and inte-
resting monthly discussion of good observations, it may
be entitled to a fair share of interest and attention.

Commencing with March 1, I find the air in gentle
motion in the southern porta of England, and passing
for the most part from the S. W. and S., tilt arriving
at Beattock, Lanark, and Edinburgh, a strong N. W.
wind was recorded. On the 2nd, the prevailing di-
rection was S.W., veering in the northern counties to
Il
S., or is other words, becoming parallel to the main
ridge of northern mountains; in the extreme north,
the wind was blowing strongly. On the 4th, the
air was evidently on its return down the country,
setting in at Glasgow, Lanark, a- ,Beattock from
the N.W., which direction shortly afterwards changed
to N., and continued in this direction to the south
coast with scarcely an exception. At Whitby on
this day a heavy gale from the N. was recorded. On
the sth, at Beattock, Lanark, Edinburgh, and Ber-
wick, a wrong breeze was recorded, the direction
being diflerent, affording strong evidence cf
the efftct of the mountain in deflecting the
coarse of the wind. With a few excep-
tions, this day was calm ; the same re-
mark applies to the 6th, with this difference, that
commencing at Holyhead, there was a fresh westerly
breeze, and the air passed in this direction over the
Western and Midland counties, the air at the same
time passing in all directions on both sides of this
current, p erticularly on its south side, where it was
mostly calm with fog. The 7th, 8:h, and 9th may be
classed as calm days ; the 10th being Sunday, I have
but few observations. The 11th was calm ;on the
12th, the air for the most part was a gentle motion,
except over the southern counties,where it wits chiefly
cake. The 13th and 14th days were calm. ,On
coming to the 15th, I find there was a gentle breeze
from the N.E., passing over those parts of the country,
extending from the south coast to Sunderland : north
of this place the direction was E. Calm and fogs
were registered at Lanark, Glasgow, and Dundee.
I On this day the recent severe weather was intro-
duced. The temperature of the air, which till this day
had been mostly above the average for the season,
declined considerably below it. On the 16th the pre-
vailing direction was N.W., but the air was deflected
in many places ; the temperature of this day was
several degrees below its average, and at night the
reading was below 25 deg. at most places. On the
17th the direction of the wind was mostly N.E. and
E.; the day was very severe, its average temperature
at most places was 10 deg. or 11 deg. below the
average (or the season, and from this time to the end
of the month the temperature cf the air was low. On
the 18th the Mr was passing in all directions, but
chiefly from the N. Oa the 19th the directions were
N.W. and N., and in many places a strong breeze was
recorded. On the 20th I find there was a westerly
current in extreme N.; a NW. wind in the
northern English counties, and which dispersed
in all directions in its progress to the south.
On the 21st the air was passing from the
N. ; on the 22nd the principal direction was from the
'W. •, on the 23rd there was a bard wind from the
N.W., with storms at some places, with snow and
hail falling at others. Oa the 25th the direction was
N.W., with a sharp frost. On the 261 the whole
ass of air N. of Liverpool passed from the east, and
below this latitude its direction was from the N.W.
On the 27th the air was in gentle motion from the F.
and N.E., at southern places, and from the W. and
N.W. at northern places; snow was falling at several
places in the soutn. On the 28th the directioni were
chiefly N. and N.W. On the 29th and 30th the
principal directions were S.E. and E , passing with
gentle motion on the former day, and rather quickly
on the latter.

The prevailing direction of the wind has been
N.W. ; the next in order of prevalence were N.,
N.E., and W. respectively ; the proportional fre-
quency of these winds were 18, 16, 11, and 10 respec-
tively. The frequency of the S. and S.E. winds
were insignificant in amount.

Fog has been very general during the month. I
do not mean solely with reference to daily occurrence,
but as having covered a large portion of the country
on the days of its appearance. Thus I find that on
the Ist, sth, 6th, 7th, Bth, and 21st it has extended
over the southern and midland counties; on the 15th,
18th, and 19th over :the northern extremity of the
country ; whilst on the 9th, 11th, 12th, 13th, 14th,
15th, and 20th its appearance has been simultaneous
over the whole of the country. By this remark I
do not wish to be understood that fog has been
recorded at every station on your list, but simply
that at many stations, in different localities, it has
been recorded in sufficient number to render the pre-
vailing emitracteristio of the period. Many anoma-
lous returns this month have been received of strong
breeze and fog, a thing impossible in nature; as these
discrepancies have been confined solely to observations
on the coast the fog 1 have referred to a sea haze or
mist.
The reading of the barometer has been remarkable;
from February 16 to March 22, with the exception of
Sunday, March 3, It was nearly equal to, or it ex-
ceeded 30 inches, at the height of 139 feet ; this is of
rare occurrence. Its mean reading for the month
was 30m., and the mean temperature of the month
was 38.2 deg., the average for 79 years is 40.9 deg.
