THE PRESBNT COLD IVEATHE.R.

The following letter has, been addressed to a
contemporary
Sir,—The temperature of the last few days haS
been so unusual in the month of November, that I
beg to send you an account of it. The mean tem-
peratureno less

below
o this i s ca
the
ayverais 37i deg.,ge of the
being
same period for 48 years. The mean daily tempe-
rature was below the average on every day except
the 4th and sth, when it was slightly above; and
on the 19th amounted to 14 deg. ; on the 20th to
101 deg. ; on the 21st to 8 deg.; on the 22d to 9
deg. • and on the last two days, viz. the 23d and
this Ciax. (the 24th), -Which were the coldest, the
depression was as large as 15 deg. and 16 deg. re-
spectively. The most remarkable period in the
month is that from the 15th, its mean temperature
being 321 deg. ; and its mean departure below the
average, amounting to 91 deg. On the 20th the
temperature decreased to 241 deg. ; on the 23d to
181 deg. ; and this raorninm:it was at its lowest
point, 16 deg. This remarkable period of continu-
ance
of cold in November is without parallel since

the year 1815 ; the weather in that year, from
November 15th to the 29th, was similar to the
present; the mean temperature between these
limits was 311 deg. The temperature, however,
did not fall so low as at present ; the lowest noted
was 25 deg. In the year 1816 there was a cold
period of three days' duration, viz., from the 22d
to the 25th, when the mean temperature was 30
deg., that of.the 24th was 231 deg. only. The next
cold period in November, of any continuance, was
in 1827, when the mean temperature of the 22d,
23d, and 24th, was 27 dogs. ; that of the 24th was
as low as 241 degs. In the year 1829, from Nov.
16th to the 25th, the mean temperature was 321
dep. The next cold Period was in 1838 ; from
the 24th to the 27th its mean temperature was 311
degs. In 1841 the mean temperature from Nov.
14th to the 18th was 311 degs. ' • in 1849 the mean
temperature from Nov. 25th to Nov. 29th was 311
degs., that of the 28th being as low as 26 degs.
In 1851 the mean temperature from Nov. 15th to
19th was 321 degs. ; in 1854 the mean from Nov.
22d to 27th was 331 dogs. ; and in 1856 the
mean of Nov. 29th and 30th was 29 degs. In Nov.
1857, the temperature of the coldest day was 37
degs., that of Nov. 26th. So that there has not
been any analogous period of such severe weather
in the month of November, as at the present time,
since the year 1815. The mean temperature of
yesterday was 25k' deg., and this day is 241 deg.,
and the mean of these two days is lower than that
of any two consecutive November days in the pre-
ceding 45 years. The temperature this morning,
viz., 16 deg., was lower than it has ever been m
the month of November within the same period of
45 years, which as far as authentic records extend.
In the year 1815 the mean:temperature,which was
29 deg. on Nov. 29th, rose to 411 deg. on Nov. 30th,
to 49+ deg. on Dec. Ist, then gradually declined to
42 deg. by the sth, and was followed by a mode-
rately cold period. JAMES GLAISHER.

DUBLIN, WEDNESDAY MORNING.
THE enmorm SQUADRON.

A letter from Caslletown lierehaven, dated the
20th inst., says :—" It having been arranged that
the gunboat Skipjack, which left a few days since
for Queenstown, was to return forthwith, bringing
witnesses for the court-martial to be held on the
third lieutenant of the Hawke, the order for the
immediate departure of the squadron, brought by
special messenger, was received on board with
much surprise and. ashore with great regret. This
morning, at 9 o'clock, the Wizard sailed out at the
westward entrance, and the Royal Albert, the Re-
nown, the Orion, and the Brunswick, all screw
steam line-of-battle ships, steamed out at the east-
ward entrance, leaving a great blank in the har-
bour, notwithstanding the presence of several sail
of merchant ships. The training brig Wizard
afforded a treat before her departure, as yesterday
she was for a considerable time envelope& in the
smoke of her guns while exercising the naval
•
cadets on board."
