yesterday mornin?, when another rather con:,ideranle
fall took place. The mercurial column had main-
tained a considerable elevation throughout the early
parts of October, rising on the 9th to within a few

thousandths of 30-5 inches. On the 16th its altitude
decreased from 30.255 to 30.155, and the 17th and
18th were characterised by a rapid and extensive call.
At 48 min. past 10 p.m. of the 18th the mercury
stood at 29.214 (the lowest reading), the extent
of the fall being 1.041 inch in three days. The
afternoon and evening of the 18th were very
wet. The mercury then gradually rose until
a quarter past 10 p.m. of the 21st„ when
it stood at 29.964 ; this rise of of an inch occupied
another three days. It may be remarked, that the
fall on the 17th and 18th was more precipitous than
the subsequent rise. On Saturday last the fall was
more rapid and greater than on Monday and Tuesday.
The lowest point was passed on the forenoon of Sun-
day, the barometric column standing (at 18 minutes
past 10), at 28-783. On this occasion the mercury
fell PlBl inch in a day and a half. The barometer
has since been rising..
These and other observations at intermediate inter-
vals, upon being projected on a suitable scale, clearly
indicate the passage of large atmospheric waves over
the metropolis of Great Britain ; and were meteorolo-
gists upon such occasions to note, as often as conve-
nient, the altitudes of the barometer (at fixed hours is
not necessary, though advisable), the passage of these
waves might readily be traced over the kingdom, and
were similar observations made on the Continent, also
over Europe.
It is an extremely interesting consideration that
these immense waves are more or less accompanied
with bad weather, especially at the time of the passage
of the minimum, or lowest reading. The writer's
experience leads him to entertain the opinion that the
falls are usually (though not always) characterised by
continuous rains, while the rises are marked by con-
siderable wind and showers, especially if the falls have
occupied comparatively short intervals, the cloud
known as cumulostratus being prevalent. Clouds of
this character generally accompany the latter half
of a rotatory gale, during which the barometer rises
rapidly.

STATE OF TRADE.
(From the Manchester Guardian.)
There was no improvement in the demand yester-
day, either for yarn or goods ; and prices of both, es-
pecially of the latter, continue gradually to decline.
At the same time, stocks of all current numbers of
yarn, and of most descriptions of goods, with the ex-
ception of printing cloth, are exceedingly light; and
most of the spinners and manufacturers are working
to order. These facts show the exceedingly prostrate
condition of the trade at the present time ; but they
also give promise of improvement at no distant period.
ROCHDALE FLANNEL MARKET, OCT. 24.—There
has been another brisk flannel-market to-day, and
pieces have been easy to sell at former prices. In
wool there is no change to report; the manufacturers
still continue to buy for immediate use.

THE MARKETS.—(YESTERDAY.
CORN EXCHANGE.
The fresh supplies of English Gram since Monday
were small, and of Irish Oats considerable. The Wheat
trade remained dull at Monday's prices. In, other
Grain not much done, and Irish Oats on rather
lower terms.
