! DO not let the thermometer fool You.
I Ii is very deceptive instrument for
those who do not know how to Use il
and sometimes for those who do. or
think they do.

some winter morning and see the mer-
curry standing at zero. Phew. You
feel a shiver at the mere sight Of that
needle of glacial metal. contracted
down almost to the bottom Of its tube,
as If seeking refuge. and gittering
there like miniature icicle cut OF
short.
You wrap yourself up as for an arc
tic journey before venturing out. thrust
your gloved hands into your big over
coat pockets. put on your ear shields.
start on a run for your office or the
railroad station in order to get your
blood into a state of defensive circu-
lation-and in two or three minutes
you are streaming with perspiration!
You turn down your collar. open your
coat and find that the air is. though
not exactly balmy, decidedly bracing
and agreeable.
Yet there hangs that thermometer.
steadily marking zero!
II has deceived you. but still IL has
told the truth-yet not the whole truth.
only the truth as it sees it, IL is Zero
weather for the thermometer. but IL Is
not zero weather for you. Evidently
your body and the thermometer have
not the same standards of measure
ment
But a few days later perhaps you
look again at your thermometer on the
porch as you are about to go about
your business. and you find that 1t
marks a very comfortable sum Of de-
grees above zero. what might truly be
called balmy weather for winter. You
have forgotten the disagreement that
you had with the instrument Of sci
ence the other morning. and you bow
again conf1dingly to lbs decree. 1t says
the air is comfortably warm. and the
thermometer surely ought to know,
since it is its sole business to measure
temperatures.
You leave OF your heavy coat and
your wraps. bare your throat and
start bravely away for office or sta
ton. trying to feel as genial as the
thermometer has assured you that the
weather is. Rut you are not halfway
to your destination before a shiver
runs down your back. your nose be-
comes an icicle. your ears smart and
burn. and you begin to sneeze or
cough. You feel that you have laid
the foundation of serious cold"
which will probably put some money
in the pocket of your neighbor, the
doctor.
But il. scared by the thought of
pneumonia, you will return home in
haste you will see as you glance at 1t
In passing that the thermometer on
the porch still stares you down with
its impudent assertions that the air
this morning is only moderately cold.

Now. where is the origin of the de-
ception and why are you warm when
the Thermometer is cold and cold when
the thermometer Is warm,
The whole trouble arises from the
essential difference between a simple
machine consisting of glass tube and
little mercury and complicated liv-
ing body with its multitude Of interre-
lated parts and functions The Their 1
mometer has only one way Of feeling
way Of responding to them-viz. by
either expansion or contraction Of the
liquid metal In its tube. The human
body Is heat engine continually ra-
dating away the heat produced within
1t by its vital processes. and its princi-
pal means of feeling changes Of tenn
perature occurring outside itself is
through the different rates at which its
Unborn heat is radiated away to sur
objects or the surrounding
air
