O., weflnd tho following instructive gen!
civilizations;
/. The rain and snow storms, and even
the moderate rains and SHOWS, travel from
the west toward the east in the United
States, during tho months OF November,
December, January, February, and
March, which arc the only months TO
which these cancellations apply.
2. The storms are accompanied with o
depression Of the barometer near the cen.
trail line Of the storm, and rise Of the
barometer in the front and rear. '1
3. This central line Of minimum nres.
sure is generally Of great length from
north TO south, and moves side.ioremost
toward the east. L Tr.'Y5I5
4. This line is sometimes nearly
straight, but generally curved, and most
frequently with its convex side to the east
g. The velocity of this limo is such that
it travels from the Mississippi to the
Connecticut river in "a hours, and from
the Connecticut to St. Johns, Newfound:
land, in nearly the same time, or about 30
miles IN hour. a-rt ....r.. ...,., ....
O. When the barometer falls suddenly
in tho western part Of New England, L
rises at the same time in tho valley OF the
Mississippi, and also at St. Johns, New.
IOnndland. ....-..
I, In great storms the wind for several
hundred miles on both sides OF the line of
minimum pressure blows toward that line
directly or obliquely.
8. The force of this wind is in propor-
ton TO the suddenness and greatness Of the
depression Of the barometer.
0. In all great and sudden depressions
Of the barometer there is much rain or
snow; and in all sudden great rains or
SHOWS there is a great depression of the
barometer next the centre Of the storm,
and rises beyond Its borders.
10. Many storms are of great and I'm.
known length from north TO south, reach.
ing beyond our observation on the Gulf of
Mexico aul on the Northern lakes, while
their east and west diameter is compare.

but some commence in the United States
IL. When storm commences in the
United States the line Of minimum pres

but commences with the storm, and tray.

IL. There is generally lull of wind al

times calm.
II. When this line Of minimum pres.
sure passes an observer toward the east,
tue wind generally soon changes 10 the
west, and the barometer begins 10 rise.
10. There Is generally but little wind
near the line OF the maximum pressme
anl on each side OF that line the winds are
irregular, but tend outward from that line

are generally greater in the eastern than
in the western part Of the United StatesI
II. The fluctuations Of the barometer
are generally greater in the northern than
in the southern part Of the United States.

States the wind generally sets in from the

wind generally changes from the east

States.

east than the southern part. ras d
92. During the high barometer on the
day preceding the storm, 1t is generally
clear and mild in temperature, especially
il very cold weather preceded.
%. The temperature generally falls
suddenly on the passage Of the center oil
great storms, so that sometimes when
storm Is in tue center of the United
States, the lowest temperature of the
month will be in the West on tho same
dry that the highest temperature is in the
East.
Some of the storms, it is true, arc con.
tanned entirely, for u time, within the
hounds oil my observation, and IN that
case the minimum barometer does not ex-
hihll itself In line Of great length, ex.
lending from north and south, but 1t is
confined TO a region near the centre Of the
storm, and travels with that centre tow.
ard the eastward. o.. u
From these experiments it may be sale.
" inferred, contrary 10 the general belief
OF scientific men, that vapor permeates
the air from high 10 low dew.point
with extreme Slowncss, II, indeed, It per-
meates at all; and in meteorology, It will
hereafter be known that vapor rises into
regions where clouds arc forced only by
being carried up by ascending currents Of
air containing It. 'Ie
