From, Our o.sn CORRESPONDENT -
CHICAGO, Nav notwithstanding that q
fog is nothing but condensed atmospheric
moisture, and may be defined as "watery
yapors precipi:ated and suspended in the lower
stratum OF the atmosphere, or in That part OF
it nearest to the ground" its effect upon Lo~
mestic animals differs very often essentially
from that at 4 very humid atrnosp phere, because
fogs, according to their source, contain fire.
quent1y foreign a1mixtures. OF an Injurious
character. Fogs originate most frequently IN
low, vet, and marshy or swampy countries, and
over large bodies OF water, and contain, there
fore, not seldom, products Of decomposition
and particles Of decomuoslnS organic sub
stances. Fogs which come from the ocean. Or
from, other large bodies Of salt water, contain
salt particles and other constituent parts
their origin in swa'nps, or in places
where gu extensive decomposition. or or
ganlc substances Is: going on, are sometimes
6urchazged TO such an extent with foreign ad-
mixtures rs to betray the presence OF the latter
By peculiar, or even fctid, smell. These last,
mentioned fogs especially can have 4 very in
furious influence, and be productive Of various
diseases, s,-probably because the same may carry
disease producing germs, aud.thereoy constitute
the means Of Introducing the latter into the
animal Organism. At any rate. The. disease pro-
ducing gerus Of swine-plague Seem to be able
to be conveyed in That way from one place to
another: Fogs which come from the ocean are
Injurious especially on account OF their chilling
effect, and, therefore, q fruitful source OF
catarrhal and rheumatic disorders. The only
measure OF prevention that can be applied
against the Influence Of q fog consists In keep
iug very susceptible animals in the stable while
the foggy weather pgeyails,
Dew may be defined as atmospheric moisture

Of Dsre and iunocuous water, which rises in
shape or steam, or vanor, from the surface Of
the earth, while the latter Is warm {durin. the
