FromIihe Phila. Ledger.
Professor Espy's first report on me-
teorology has been laid on our table.
1t consists chiefly of charts, exhibiting
by various symbols, the wind and bar
ometric fluctuation, land changes of tenn
perature, which accompany storms as
they pass from the western to the cas-
tern part of the United States; for it
appears that all storms in the United
States travel towards the east. We
extract from the report the following:
"GENERALIZA TIONS.
"lst. The rain and snow storms, and
even the moderate rains and SHOWS,
travel from the west towards the east
in the United States, during the months
of January, February and March,
which are the only months yet investi-
gated.
"2d. The storms are accompanied
with depression Of the barometer
near the central line of the storm.
"3d. The central line of minimum
pressure is generally of great length
from north to south, and moves side
foremost towards the east.
"4th. This line is sometimes nearly
straight, but generally curved, and most
frequently withhls convex side towards
the east.
"5th. The velocity of this line is
such, that il travels from the Mississip-
pi to the Connecticut river in about
twenty-four hours, and from the Con-
necticut to st. John, Newfoundland, in
nearly the same time, or about thirty
six miles an hour.
"6th. When the barometer falls sud-
denly in the western part of New Eng
land,it rises at the same time in the val
ley of the Mississippi, and also at st.
John, Newfoundland.
"7th. In great storms, the wind, for
several hundred miles on both sides o.
the line of minimum pressure, blows
towards that line directly or obliquely.
"8th. The force Of the wind is in pro-
portion to the suddenness and greatness
of the barometric depression.
"9th. In all great and sudden depres-
sions of the barometer, there is much
rain or snow; and in all sudden great
rains or SHOWS, there is a great fuctu-
alton Of the barometer.
"1Oth. Many storms are Of great and
unknown length from the north to the
south, reaching beyond our observers
on the Gulf Of Mexico and on the nor
thern lakes, while their east and diam
eteris comparatively small. The storms
therefore move side foremost.
"1lth. Most storms commence in
the "Far West" beyond our most wes-
tern observers; but some comm ence in
the United States.
"l2th. When storm commences in
the United States, the line Of minimum
pressure does not come from the "Far
West" but commences with the storm,
and travels with it towards the East.
"1sth. There is generally lull Of
wind at the line of miHimum pressure,
and sometimes a calm.
"l4th. When the wind changes to
the west, the barometer generally be-
gins to rise.
"i5th. There is generally but little
wind near the line of the maximum
pressure, and on each side of that line
the winds are irregular, but tend out
wards from that line.
"1Gth. The fluctuations of the bar
ometer are generally greaterin ;he nor
thern than in the southern parts Of the
United States.
"17th. The fluctuations ofthe barom-
tier are gensrally greater in the east
,rn than in the western parts OF the
United States.
"l8th. In the northern parts OF the
United States, the wind,in great storms,
generally sets in from the north Of east,
ind terminates from the north of west.
"l9th. In the southern parts Of the
United States tie wind generally sets
n from the south OF east, and termin-
ties from the south of west.
"2Oth. During the passage of storms,
he wind generally changes from the
eastward TO the westward by the south,
in the southern parts Of the |
United States"
