Curious Meteorological Facts.

In the fourth meteorological Report by
Professor J. P. Epsy, of Washington, D.
c., we find the following instructive gen.
eralizations:
!. The rain and snow storms, and even
the moderate rains and SHOWS, 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 a
depression of the barometer near the CEN
trail line of the storm, and 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 the east.
4. This 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-
from the Connecticut to st. John, New
foundland, in nearly the same, or about
thirty-six 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.
T. 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.
ton to the suddenness and greatness OF
the depression of the barometer.
8. In all great and sudden depressions oi
the barometer there is much rain or snow
yand in all sudden great rains or snow there
is great depression of the barometer
near the center of tie 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 O
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 fal
| West" beyond our most western observ
ers, but some commence in the United
States.
| 10. When a storm commences in the
United States, the line of minimum press
ure does not come from the far West,
but commences with the storm, and travels
with it toward the eastward.
13. There is generally a lull of wind a
the line of minimum pressure, and some
times calm.
IA. When this line of minimum press
ure passes an observer toward the east
the wind generally soon changes to thu
west, aud the barometer begins to rise.
Is. There is generally but little wine
near the line of minimum pressure, anC
on each side of that line the winds are ir
regular, but tend outward from that line
16. The fluctuations of the baromete
are generally greater in the northern thai
in the southern parts of the United States
II. The fluctuations of the baromete,
are generally greater in the eastern thai
in the western parts of the United States
49, In the northern parts of the Unitet
States, the wind, generally in great storms
sets in from the north of east and termi
mates from the north of west.
19. In the southern parts of the Unitet
States, the wind generally sets in from th
south of east and terminates from tn
south of west.
20. During the passage of storms tn
wind generally changes from the eastWar
to the westward by the south, especlall
in the southern parts of the United Sta eli
81. The northern part of the storm gen
orally travels more rapidly towards tn
east than the southern part.
%. During the high barometer on tn
day preceding the storm it is general,
clear and mild in temperature, especiall,
if very cold weather preceded.
%. The temperature generally falls sud
denly on the passage of the center O
great storms, SO that sometimes, Wien
storm is in the middle of the Unite,
States. the lowest temperature of tn
month will be in the west on the sam
; dsy that the highest temperature is j
the east
Some of the storms, it is true, are con
tanned entirely, for time, within tn
bounds of my observers, and in that cas-
the minimum barometer Goes not exhibi
itself in line of great length, extendin
from north to south, but it ia confined t
: a region near the center of the storm, an,
travels with that center toward the east
ward.
From these experiments it may safel
be inferred, contrary to the general belle
of scientific men, that vapor permeates tn
air from high to low dew point wit
extreme slowness, if, indeed, it permeate
? it at all and in meteOrolOgy, it will here
after be known that vapor rises into tn
, regions where clouds are formed only b
being carried up by ascending currents {
