and not return towards midnight to its
altitude in the morning, then change is
sure to follow. We notice this change in
a Timay's Barometer which hangs by
our side as we write this-Tuesday P. NJ,
(Sept. 4th, (Which has declined one
tenth of an inch since o'clock this morn
ing. AS it fell in a similar manner yes
terday, and rose again at nightfall, we
no change unless this decline
continues. 1t was knowledge of these
changes which led us last week in MOTTO
ing this instrument, to caution people
against imputing to that, faults which ex-
list only in their own ignorance of it's
principles, and to advise them to obtain
an understanding Of the laws which gov
ern it, before judging falsely Of its indi-
cations. Mr.. Timby's Barometer is SIM
pie instrument, its indications plain to be
read and easy to understand. We believe
it to be thoroughly made, as the mercury
has that brilliant lustre which bespeaks
its purity, and in inclinlng the tube it
strikes against the top with sharp click
which indicates perfect vacuum. These
points show correct construction; and
as the principle of the barometer's action
is Interchangeable, it follows that a correct
and careful construction Of the instru-
ment is all that is needed, to make it as
perfect as any instrument of the kind can
be. l fy4t.ts.. ..a5, ra1 E TaL
This article is already longer than we
designed, and we close by giving the fol-
lowing rules from distinguished English
authority, which we advise all who owna
barometer to preserve and consult:
l.. After a continuance of dry weather,
if the barometer begins to fall slowly and
steadily, rain will certainly ensue; but
if the fine weather has been of long du-
ration, the mercury may fall for two or
three days before any perceptible change
takes place and the longer the time that
elapses before the rain comes, the longer
the wet weather is likely to last. .edf
2. If, after great deal of wet wealth
er. with a low barometer, the mercury
rises slowly and steadily, fine weather
will come, though two or three days may
elapse before the change; and the fine
weather will be permanent in proportion
to the time that passes before the percep-
tible change takes place. if .tl1oE
B. If a change of weather Immediate
ly follows the motion Of the mercury, the
change will not be permanent. aat es.l
4. If the barometer rises slowly and
steadily for two days or more, fine wealth
er- will follow, though it should rain in
cessantly during these two days. But if
on the appearance Of fine weather, in the
above instance, the mercury begins to fall
again, the fine weather will be very tran
sient Apply thereverse of this in change
from fair to rainy weather. HJ ei-9
5. A sudden fall of the barometer, in
spring or fall indicates wind; in the sum-
mer, with sultry atmosphere, an approach
ing thunderstorm; in the winter, if af-
ter continued cold, change of wind
with thaw and rain. Or should the cold
be unabated and the mercury fall, snow
may be expected. @ ad t Ei'f2'ai'
6. Rapid fluctuations of the barome-
ter do not indicate permanent change Of
weather; only the slow, steady and CON-
tinued changes of the mercury. n
Local atmospheric influences may vary
: these rules somewhat, and therefore expe-
rience is necessary to enable person. to
Judge with entire accuracy in any case.
