Curious Meteorological Facts.

In the fourth meteorological Report b.
Professor J. P. Epsy, Of Washington, .
c., we find the following instructive gen
civilizations:
l. The rain and snow storms, and evcl
the moderate rains and SHOWS, travel from
the west toward the cast in the Units
States; during the months of November
December, January, February and March
which are the only months to which thes'
gencralizations apply.
3. The storms are accompanied with
depression Of the barometer near tho cen
trail line of tho storm, and rise of tn.
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 fOremos,
toward the east.
f. This line is sometimes nearly g raight
| but generally curved, and most frequently
with its curvex side toward the east
g. The velocity Of this line is such that
it travels from the Mississippi to the Con.
necticut River in twenty-fo hours, and
from the Connecticut to St. John, New
foundland, in nearly the same, or abou,
thirty->ix uiles al hour
6. When the barometer falls suddenly
M the western part Of Now England, it
rises at the same time in the valley of the
Mississippi, and also at St. J,hn, New
fOundland.
7. In great storms the wind for several
hundred miles on both sides OF the line OF
directly or obliquely.
ton to the suddenness and greatness of
the 10 ,>racoinn IF tho hop
8. In all great snd sudden depressions of
the barometer there is much rain or snow i;
and in all sudden great rains or snow there
is great depression of the barometer
near the center of the storm, and rise be-
yond its borders.
TO- 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.
West" beyond our most western Observ-
States.
-. When q storm commences in the
United States, the line of minimum press
ure does not come from the "far We,t,"
but commences with the storm, and travels
with 1t toward the eastward.
IL. There is generally lull Of wind at
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 coanges to the
west, and the barometer begins to rise.
10. There is generally but little wind
near the line of minimum pressure, and
on each side of that line the winds are IT.
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.
16. In the northern parts Of the United
States, the wind, generally in great storms,
sets in from the north Of east and termi-
mates from the north 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 Sta es.
81. The northern part of the storm gen.
orally trases more rapidly towards the
east than tie 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, wGen
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 mibimum barometer does not exhibit
itself in y line of great length, extending
from north to south, but it il confined to
reg ion near the center of the storm, and
travels with that center toward the east
ward
From these experiments it may safely
be inferred, contrary to the general belief
IF scientific men, that vapor permeates the
air FROM high to low dew point with
extreme slowness, if, indeed, it permeates
it at all and in meteorology, il will here.
after be known that vapor rises into the
regions where clouds are formed only by
beng carried up by ascending currents of
