HOT WEATHER, AND ITS EFFECT9,

ront number Of tho Popular Science MoAihiM
the timely topic Of tho Morbid Efocts Of Heat
The subject las less importance in Chicago,
perl,aps, titan in any city in tho country, for tho
reason that our heated term is Bhortor, and,
therefore, less oxlsausting than TINT Of any
crowded community in tho Northern States
But in choloEa Aoason, and with tho nnticipa-
tion Of warm weather during tho present month
and part Of September, it is woil TINT people
should giyo somo attention to the intluoncoa
Of heat and tho bost measures to countoract
them. We nro told tint the natural. temperature
OF the human body is 09o Fahr., and, III healthy
condition, this temperature yaries but little
oithor WY. Tho body il described as furnace;
tho food is The fuol and tho ar taken into tho
lungs s the lrauyht which asaists combustion.
In lealth tho cxcoss Of heat Ia thrown OF partly
through the lungs, Kidneys and skin, with tho
wasto matter, aud partly by conduction md ra-
diaton. 1t ia an essential condition of health,
then, to maintain tho oven and natural temporal
turo Of iho body. Neither tho cold nor tho heat
OF tho atmoaphoro can bring discaso if tho
temperature Of tho body can bo preserved in it's
natural condition. illus, men have exposed
themselves in Ill oyon to a l1oat of EGO dogreoa
Fahrenheit without any serioua results, under
favorable circumstances for evolving tho oxcoss-
i've supply from within. So long as tl!o mir was
kept dry, and the other conditions wore favora-
bic, the heat OF tho body WAS kept down by por-
spiration; but, whom moisture was admitted,
evaporation WAS retarded and the temperature Of
| tho body arose. The most dangerous effect Of
hoat in it's direct influence on the body is tho
production Of ther1nio fever, OF sunstroko. Un-
der this goneral hoad may be included various
forms Of disoaso TINT partako Of tho Same nature
and arc brought on by tho salno cause. It will
| bo now to most readerH to loarn that Hunstroko
aud its notifications do not require O direct ac-
| tion Of tho SUMS rays on tho head or body. Ex-
perieuco has proved this to bo truo. It has boon
found in India that mon have boon attacked DUR
ing tho night aftor going to bed In apparently
healthy condition. Artificial heat, auch as TINT
Of d hotol-laundry or a sugar-rolnory, has boon

the British soldiers was abandoned in Inlia on
thia account. Oyorerowded rooms aud poor y0n-
tilation have also boon found to promote the
