Ia the fourth meteorological report
by Professor J., ?. Epsy, Of Washing
ton, y. c., we find the following iu-
SVuctive grncralizstions:
l. The rsin and snow storms, and
Uen the moderate r'ins and SHOWS,
Hsvel nom tho west toward the east
In the United States, during the
Honths Of November, December,
January, February and March, which
are the only months to which these
EeneraliAtions apply.
I. The storms are accompanied
with a depression Of the barometer
IVY the central line Of the storm,
md a rise Of the barometer in the
front and rear.
3 This central line Of minumuG
pressure Is generally Of great length
Rom north to south, and moves side
foremost toward the east,
4 This line is sometimes nearly
Itraihgt, but generally curved, snd
most frequently with its ccnyex side
toward the east.
q. The velocity Of this lire Is such
thot 1t travels from the Mississippi to
the Connecticut River in abonttwen-
tv-four hours, and from the Connect
6ut to ST. John, New Foundiand il
nearly the same, or about tlirty-'l1
SAtles an hour.
6. When the barometer ialia sud
denly in the western part OF New
Engi.nd, it rises at the same time in
,he valley OF the Mississippi, and also
At ST. John, New Foundland.
7. In great storms the wind fo.
several hundred miles on both side:
Of the minimum pressure blows to-
wards that line directly or ohliquely
s. The FORE of the wind Is In pro.
portion to the suddenness and great.
ness of the depression OF the baron
c1rr.
0. In all great and sudden 1cprcs.
sions Of the barometer there is mucl
rain or snow /; and in all sudden great
rains or snow there is great depres'
sion Of the barometer near the cen
ter Of the storm, and rise beyond it
bonTers.
10. Many storms are Of great an(
unknown length from north to south
reaching beyond our Observers OF
the Gulf OF Mexico and OF tht
northern lakes, while their east anC
west diameteris comparatively small
The storms therefore move side lore,
most,
IL. Mott storms commence in th,
"fAr West" beyond our most wcsteri
observers, but some commence in III
United States.
II. When a storm commences il
che United States, The line Of minu
mum pressure does not come from
the "far West" but commences wit
he storm, and travels with it towar
the eastward.
10. There is generally q iuii 0
wind at the line Of minumnm pres;
ure, and sometimes a calm,
IA. When this line Of minGmur
pressure passes an observer toWar
the east, the wind generally 500
changes to the west, and the bar0mt
ter begins to rise.
IL. There is generally but it'll
wind near the line Of minumrl
pressure, and on each side OF tn
line the winds arc irregular, buttcn
outward from that line.
16. The fluctuations of tho baron
eter are generally greater in Il
northern than the southern parts
the United States.
II. The fluctuations Of the baron
cier are generally greater in the cas-
ern than in the western parts Of Il
United States.
IS. In the northern parts OF II
United States, the wind, general
in great storms, sets in from Il
north Of east and terminates front
north of west.
~. In the southern part Of Il
United States, the wind general.
sets in from the south of east and to
miGates fom the south of west.
90. During the passage of storr
The wind generally changes from Il
eastward to the westward by q
south, especially in the southel
parts OF the United States.
q. The northern part of the stor
generally travels more rapidly
wards the east than the southe.
part.
%, During the high barometer (
The day preceding the storm it is &c
orally clear and mild in temporatuT
especially if very cold weather pr
ceded.
%. The temperature generally fl'
suddenly on the passage of tie &C
ter of great storms, so that sometime
when a storm is in the middle of Il
United States, the lowest temper
ture of the month will be in the We
on the same day that the highC
temperature is in the east.
Some of the storms, 1t Is true, q
contained entirely, for a time, with
the bounds of my observers, and
that case the minimum baromet
does not exhibit itself in a line
great length, extending from north
south, but it is confined TO a reggie
near the center of the storm, al
travels With that center toward Il
eastward.
From these experiments it mi
safely be inferred, contrary to t
general belief Of scientific men, tn
