colder body, the almost here, till their

l,alations will consequently arise from all
the grounds of cities and elsewhere,
which are composed from materials cap
able OF yielding them.
The same effects are produced from
waters; bnt the evaporations are more
s.r less pure, according tot!,eir. current
of stagnant and putrid state.f Large bo-
dies of dead vegetable matter III marshes,
which are common in the interior parts
Of the country, before they BECOME clear.
ed, may be acted on blythe same causes.
And although these causes act on all
parts of the country, still the effects are
comparatively innocent on the human
constitution, because the qualities Of the
ground do not yield exhalations of SO
noxious kind, to any great extent;
and where there are gramlDous or other
vegetable productions growing, they con-
sumo it with great avidity. Besides,
the exhalations must be largely emitted,
and must continue for length OF time,
as their specific gravity in most or all Ca
ses. is supposed to be less than that OF
the atmosphere air, and will SOON ascend
beyond the region of action. The dele.
terious effects, therefore, depend on a
cloud or eXhalations pretty constantly
rising from the water or the ground.
Consequently
/. If the aboye positions be true, and
the consequences | have drawn from
them be true also, a combination of those
causes may take place every season, Or it
may take place once i'll ten, twenty, fifty
or an hundred years. -:
g If also they be true, we shall gene
rally find during the fever season, that
very cool nights, or cool days, or both,
have tendency ~ increase the cases OF
fever, unless the cold be sufficient to re.

perature which vii! couDteract the effects

sequences be true, human efforts can
certainly do much in cities, towards ap-
plying prevcntives, by covering the up.

lime, thick pavemsnts, or other substan-
ces. The immediate Cause acting on
the constitution, will always be brought

|, is to be understood that the above
remarks are to be considered abStracted-
ly from any effect OF heat, cold, or hu-
midity, acting either as exciting causes
or otherwise, on the constitution. My
differences are not to be supposed incom-
patiblc with many other effects from
those causes, which are left to others to
investigate. M.

At S.oddKtsvi we went together to
visit Stodd,rt's merchant mill. 1t is a
noble building, think IS by SIS feet,
and upwards of 70 .eet in height OH the
water side. 1t is situate at the fall of the
Lehieh, and the race is cut $50 feet
through rock.
The wheat on delivery is poured into
hole III the floor, from whence it is ia
ken by machinery and carried into the
fourth story, from thence, when wanted,
it rs taken, still by machinery. and carri.
