Curious Meteorological Facts.

| In the fourth meteorological Report by
Professor ]. P. Epsy, of Washington, d
c., we find the following instructive gen
Civilizations:
l. The rain and snow storms, and ever
the moderate rains and saows, travel from
the west toward the east in the United
States, during the months Of November
December, January, February and March
which are the only months to which these
generaliZations apply.
2. The storms are accompanied with 9
depression of the barometer near the cen.
trsl line of the storm, and a rise of the
barometer in the front and rear.
3. This central line of minimum pres
sure is generally of great length from
north TO south, and moves side foremost
toward tie east.
tins line is sometimes nearly straight
but generally curved, and most frequently
with its curvex side toward the east.
5. The velocity Of this line is such that
it travels from the Mississippi to the Con-
necticut River in twenty-four hours, and
from the Connecticut to st. John, New
foundland, in nearly the same, or about
thirty-sK miles an hour.
6. When the barometer falls suddenly
in the western part of New England, it
rises at the same time in the valley of the
Mississippi, and also at st. John, New
foundland.
z. 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.
s. The force of the wind is in proper

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 snow there
is q great depression of the barometer
near the center of the storm, and rise be-
yond its borders.
10. Many storms are of great and un-
known length from north to south, reach
ing beyond our observers on the Gulf of
Mexico and on the northern. lakes, while
their east and west diameter is compare
lively small. The storms therefore move
side foremost.
II. Most storms commence IN the far
West" beyond our most western observ-
ers, but some commence in the United
States.
l2. When a storm commences in the
United States, the line of minimum press
ure does not come from the far Yves"
but commences with the storm, and travels
with it toward the eastward.
13. There is generally lull of wind at
the line of minimum pressure, and some
times q calm.
IA. When this line of minimum press
ure passes an observer toward the east,
the wind generally soon changes to the
west, and the barometer begins to rise.
15 There is generally but little wind
near the line of minimum pressure, and
on each side of that line the winds are ir-
regular, but tend outward from that line.
16. The fluctuations of the barometer
are generally greater in the northern than
in the southern parts of the United States.
II. The fluctuations of the barometer
are generally greater in the eastern than
in the western parts of the United States.
1S. In the northern parts of the United
States, the wind, generally in great storms,
sets in from the north of east and termi-
nstes frOm the Forth of west -
10. In the southern parts of the United
States, the wind generally sets in from the
south of east and terminates from the
south of west.
20. During the passage of storms the
wind generally changes from the eastward
to the westward by the south, especially
in the southern parts of the United States.
81. The northern part of the storm gen.
orally trage,s more rapidly towards the
east than the southern part.
%. During the high barometer on the
day preceding the storm it is generally
clear and mild in temperature, especially
if very cold weather preceded.
%. The temperature generally falls sud-
denly on the passage of the center of
great storms, so that sometimes, when a
storm is in the middle of the United
States, the lowest temperature of the
month will be in the west on the same
day that the highest temperature is in
the cast
Some of the storms, it is true, are con-
tanned entirely, for time, within the
bounds of my observers, and in that case
the mipimum barometer Goes not exhibit
itself in line of great length, extending
from north to south, but it is confined to
a region near the center of the storm, snd
travels with that center toward the east
ward.
From these experiments it may safely
be inferred, contrary 10 the general belief
Of scientific men, that vspor permeates the
air from high to low dew point with
extreme slowness, if, indeed, it permestes
it at ali; and in meteorology, il will here.
after be known that vapor rises into the
regions there clouds are formed only by
being carried up by ascending currents of
