The n1tural event is too well known: andit is
the huiineis of art to endeavour 10 prevent it.
II, by cutting down the crop, as foon asst is
found to be difeafed, the operation can be ltop,
ped,-as experience, in different initances, has
aiown that it nay,--the remedy is eafy. A
probable mean Of prevention is that of inducing
early ripenefs for reafons above offered y either
by towing carly; or hy forcing mannres; or
by feleeting and eftabli0ling early varieties-of
| wheat mott Especially las early varieties of
peas, and other efcusnt plants, are RATED by
gardeners "a work which only requires ordi-
nary attentions and which, it is hoped, will.
without delay, be fet about and encouraged,
by every attentive grower of wheat, aad every
promoter of rural improvements, in the united

According to Mr.. BRRNDE's view of the the
CRY of reipration, the blood is propelled, by the
contraction of the heart, into the pulmonary ar
terry, which, BY its numerous manifestations, con-
! veys the blood into the fmali branches ct thei
air cells of the lungs, which of 70 fine tex
| ture rs to admit the Absorption of a portion of
air. The blood, having undergone this al;erat-
on, is returned into the heart by the pulmonary
| veins, from whence it is circulated over the
whole body. During the circulation, the air
| which has been Authorized undergoes gradual
| decomposition; carbonic acid and water are
formed, which, together with portion of azote,
| are returned by the veins, and thrown out as
the blood pales through the lungs. fre!h
portion of air is at the fame time a!forbed, and
the above changes repeated.
The following is faid to be good method Of
preierving hops for the purpofe of brewing ::
DrltiI Quantity of hops with water; feparate1
the efIcntial oil from the diltilled water, prefs
the hops, boil them again, and evaporae to the
confidence Of exiraet, addiug TO them the ditill-
ed water. When they are TO be uicd, pound
the eiIentiaI oil with a fnalI quantity OF fusar,
| and diifoive it together with t extract in the

/ The government OF Bavaria is making great
] exertions to- accelerate the Improvement of that
Electorate, and is expending large furns i'm vari-
1 oas ways for this purpofe. Foreigners, emil
nent for their fkil, either in the ufcful orna-
mental arts, are invited by rewards TO reide in
that country. A new academy Of fciences has
been founded at Munich under the direction of
| Count RuMFoRD, who has been named its pre-
fident. To this SoMmsRINe and other men of
learning have been already appointed with
handiome falares. A large observatory has
been built, and furnhed with whatever may be
aceountet rcefi1ry TO render it complete.
| Mr.. JEFFERSON, the pre6dent of the United
States of America, has fet on foot a journey, the
tobiea of which is to explore the river MifIouri,
as far as it's fource then 70 Wifi the neareit RI
yer ftuated to the Wet, and to defend thence
to the Pacific Ocean; to examine the natural
hitory Of the regions through which the travel
lers pats, and to aioertain an exact geography of
that interefing channel efcommunication acrnfs
thecontinent. The pretentexpedision is under
taken by twelve perfons, who will probably re-
turn towards the -eGd of the prefent year. This
truly patriotic Prchdent hopes to- be able in the
courie of the next Hummer TO tend other travel
lers towards the principal branches of the Milf
| jhippi and the Mifouri, the Red River to Ar
can't, Padoruas, and the river Miiffiippi itielf.
| The objects of theie expeditions will be the
fame as thofe of the prefent, and will require a.
bout two years to accomplish them in. Several!
of thefe rivers extend TO one thouiand, or one
| thouiand two hupdred miles inlaad, reckoning
from their fources, and into regions never Witt

M. MAsRcHAux has invented new and We
ry fen6ble eiectrometer, which he calls mi
cro-ele6trometer. 1t couiifs of g lafs cylinder,
about an inch and 4 half in diameter, and five
or fix inches high; in this piece of leaf-hlver
is fufpended from FINAL pair of nippers, capa-
bic of being lowered or elevated. The piece
that carries the nippers may likewife be moved
| horizontally, 70 that the leaf may be moved
! nearer 10, or further from, afphere of copper,
wiichis one OF the poles of the inftrument. I'll
a Tender glafs tube be rubbed but twice, and
brought within feveral inches of its fummit, !,
paf1es through the whole extent of its fca'c On
account of its great fenibility, and becaufe on
Iy very weak degrees of electricity can be mca-
fured by it, the inventor calls it hiero-eleetro-
meter.
The following is a new and economical me.
shod invented by III. GoFTTLING for ftparat-
| ing copper from FLYER. Having afcertained tie
proportion of FLYER in the alloy: take one part
of fdphtltc acid for every part OF 6ivrr, and for
every part ofcopper, three parts and ihree-6fths
of a part of the fame acid. Dilute the acid W.T.
BALI its weight of water, and pour into mat
rafs on the alloy reduced TO very fpal pieces.
The matrals is then to he placed in fand heat
and the acid brought to (tate of ebuIlition. /,
two or three hours, the alloy is converted int
fuipBate while it is fill hot, add tx eight
tines its weight OF boiling water. The fIphste
of copper will lie difolved, and great part of
the fulpl'ate Of FLYER will be pfecipitsted.
