Fahrenheit Always Popular.
Fahrenheit. however, Professor Fahr-

Away pack in lila he invented the mer-
curry instrument. Fahrenheit was a
doctor, and he built his thermometer
both ways from the temperature OF, the
human blood. That ia. he thought he
| did. He placed It at 100, but made al
| error somehow OF two degrees. Profess
sor Fahrenheit also had a huncll that
he knew what real ringing cold wealth
cr was. He said: '1f j take cracked Zee
and water and. salt, N put the bulb of
| my thermometer in 1t, I will get the
coolest temperature that is possible Ii
this world. Which he did, beginning
mis- scale at zero. This was a joke. but
Professor Fahrenheit never knew it.
Any schoolboy in the country could
have given the old cold maker a frozen
ear and two chilblains and still ave
known more about real genuine cold
than the saNant could have imagined in
three weeks.
But Fahrenheit was not the first
thermometer manufacturer. Their
mometer' is a Greek word meaning
heat measurer.' which shows. il 1t
shows anything, that the Greeks never
invaded this territory in ancient
days. Galilio. of Parthia, was the real
man who discovered thermometers.
Nobody else in those ancient days had
the least knowledge of measuring tenn
peratures. Neither did Gallo. His
thermometer was Il tube filled with
water n inverted in 81 open pan,
where atmospheric pressure and tad
poles and other unscientif1c phenomena
could interfere with the temperatures.
This was in 1892. when the world was
just beginning to cool off enough for
use among persons not affiliated with
the iron monlders' union. Next Deb

were also used, and SO were alcohol
n water measures until Fahrenheit
came along.
Alcohol has q. very large co-eficient,
as many independent investigators
have discovered when they tried to
make thermometers of themselves.
They went up amazingly. Alcohol has
a much larger co-efficient than mer-
curry and is inaccurate, but it can be
used best in this and other cole
spots where the ordinary mercury
freezes and becomes useless.
Great Many Varieties.
Among foreign and domestic ther-
mometers may be noted the gas tller-
moneter, the air thermometer. the NV
drogen thermometer. the nitrogen Their
l1-frieter, the platinum resistance ther-
lnolneter, the metallic thermometer the
weigh thermometer. the wet buIh

uncles of the Fahrenheit. The ny,.o-
