The ightest veil is something Of q vest
ment, as il serves to moderate the loss by
radiation from naked body. It is in the
same way that cloudy sky protects the
earth from being too much cooled; the
| dew will only fall when the clouds are alb
sent In putting on numerous coverings We
succeed in diminishing the radiation from
our bodies, as il by a series Of stopping of
places or relays. Our linen underclothes
and our cloaks make up numerous artificial

skin goes 20 warm the superimposed cloth.
ing. the worse the conductor the slower
the heat will pass through; when it arrives
al the surface it goes of, but without our
perceiving it, as in direct contact OF the air
We should, since it is not We, but the clothes
that get cold. What renders our clothes q
protection TO US is their being waide1 with
layer Of warm air. the temperature Of
which is maintained at between % degrees
and 30 degrees c. Each OF us thus has his
own little atmosphere that follows him
everywhere AMI renews itself without got
ting cold An animal in its fur has its
couch Of air in the intersticss that increases
the protecting power. Furs. soft stuffs and
feathers owe their warmth to the air that
they contain.
1t is evidently question Of great interest
to determine by experiments the facility
with which the various stufYs used as cloth
ing are traversei by the heat Ths cele-
bratei Count Rumford was the first who
particularly studied these experiments. He

The ball was first put in boiling water. and
then into q cooling mixture, and he noted
the time it took the Thermometer TO descend
from 20 degrees r TO 10 degrees r, to lose
20 degrees r as degrees c. When the
Thermometer was bare, it cooled in 9.5
minutes. When it was covered with linen
