WHY THE DOG PANTS?

Nearly ninety per cent OF the heat loss OF
the body occurs through evaporation OF water
duction from the skin. Ten per cent Of the
heat loss occurs through tho warming or ar
by the lungs and the appreciation OF water
from the lungs-4ho expired air 10 nearly sat
urated with water vapor y
A dog pants in very hot weather because the
dogs skin IL not equipped with vas9motor
man, react to heat by producing sweating, and
the dogs hair interferes with free loss or heat
by radiation, so the dog has to do the best nc
vaporizlng more water through the air ne
broathos. He pants to keep cool.
Having learned that ordinary air contains
only parts Of carbon Gaoxide nt ma naru
parts of carbon dioxide In O. thousand, some
persons imagine that 1t Is the Increased. proper
ton of carbon dioxde In the air that accounts
for tho III effects Of "foul" air. This Is not 80.
nor Is the depressing effect Of vitated or I'm.
pure" air due to the diminished proportion OF
oxygen In the expired air (ordinary air contains
moro than 200 parts OF oxygen IN o thousand
and the expired breath only 10 parts). 1t has
been proved over and over again that no un-
pleasant consequence occurs when an individu.
al breathes air containing the proportions or
carbon dioxide and oxygen round In expired air.
When the comparatively harmlessness OF ex-
pired air was scientifically established some
persons conceived theory that an unrecog.
niYed toxin" or ''ptomaine" or similar organic
poison exhaled from tho lungs might account
for the Ill effects of bad" air. But this tho
DRY Is no longer entertained.
we know that the disagreeable symptoms
produced by exposure to foul air and pre-
vented or relieved by fresh" air are due to
overheatng Of the air Increased humidity or
