apply.
Second-The storms are accompanied
with depression of the barometer neal
the central line of the storm, and rise
in the barometer in the front and rear
Third--This central line OF minimum
pressure is generally of great length
from north to south, ami moves side
foremost toward the east.
Four;h-~This line is sometimes nearly
straight, but generally curved, and
most frequently with its convex side to
the east
Fifth--The velocity OF this line il
such that it travels from the Mississippi
to the Connecticut river in twenty four
hours, and from the Connecticut to St.
John, Newfoundland. in nearly the
same, or about thirty~six miles an hour.
Sixth--When the barometer falls sud-
denly in the western part of New Eng
land, it rises at the same time in the
valley of the Mississippi, and also at st.
John, Newfoundland.
Seventh-In great storms the wind
for several hundred miles on both sides
of the line Of minimum pressure blows
toward that line directly or oblique]y.
Eighth-The force of this wind is in
proportion to the suddenness and great
ness of Me depression Of the barome-
ter.
Ninth-In all great and sudden de-
pressions of the barometer there is much
rain or snow, and in all sudden great
rains or SHOWS there is a great depres-
sion Of the barometer next the centre of
the storm, and rise beyond its borders
Tenth-Many storms are Of great and
unknown length from north to south,
reaching beyond our observation on the
Gulf Of Mexico or on the Northern
Lakes, while their east and west diam
eter is comparatively small. These
storms, therefore, moved side foremost
Eleventh-Most storms commence in
the far west" beyond our western OBJ
servers, but some commence in the
United States.
Twelfth When a storm commences
in the United States the line of mini
mum pressure does not come from the
" far west,' but commences with the
storm, and travels with it toward the
eastward
Thirteenth-There is generally lull
Of wind at the line of minimum pres
sure, and sometimes calm.
Fourteenth-When thi. line of mini
mum pressure passes an observer toward
the east, the wind generally soon
changes to the west and the barometer
begins to rise.
Fifteenth-There is generally but lit
tie wind near the line of the maximum
pressure, and on each side of that line
the winds are irregular, but tend out
ward from that line.
Sixteenth-The fluctuations of the
barometer are generally greater in the
eastern than in the western part of the
United States
Seventeenth fluctuations of the
barometer are generally greater in the
northern than in the southern part of
the United States.
Eighteenth-In the northern part of
the United States the wind generally sets
IL from the north of east and termin-
ates from the north of west.
Nineteenth-In the southern parts of
the United States the wind generally
in from, ha Of 4
terminates from the south of west
Iwentieth-During the passage of
storms the wind generally changes from
the eastward to the westward by south,
especially in the southern parts Of the
United States.
Twenty-tirst-The northern part Of
the storm generally travels more rapidly
toward the east than the southern part
Twenty. second-During the high
barometer on the day preceding the
storm it is generally clear and mild in
temperature, especially if very cold
preceded.
Twenty thrd-The temperature gen
orally falls suddenly on the passage of
tilC SSltic vi < leat stOTllls, SO Iual some |
times, when a storm is in the middle of
the United States, the lowest tempera-
ture of the month will be in the west on
the same day that the highest tempera-
ture is in the east.
Some Of the storms, it is true, are con |
tanned entirely, for time, within the /
bounds of my observers, and in that |
case the minimum barometer does not
exhibit itself in a line of great length.
extending from north and south, but it .
is confined to a region near the centre
of the storm, and travels with that cen
ire towards the eastward.
From these experiments it may be
safely inferred, contrary to the general
belief Of scientific men, that vApor per
meates the air from a high to a low dew
point with extreme slowness, if, indeed,
it lermeates at all; and in meteorology,
twill hereafter be known that vapor
rises into the regions where clouds are
forced by being carried up by ascending
currents of air containing it.-Scientifc
