content of the
fire-place
3. No of cubic
feet of air in
the room
4. Degree of natural
heat - to
say 40</p>

Calefactive power
depends on
1. Quantity of heated air discharged
in a given
time.
2 Degree of heat
of the air so discharged.
<p>The q density
being given . the
quantity discharged
in a given time
will be in the
joint ratio of the

Table showing
by what different
proportions of
airs of the different
heats air of
a given heat may
be produced

The natural
air being at 40
required the different
portions proportions of
air by which
it can be raised
to 50. reckoning
from 41 to
212.

The greater
the quantity
of air discharged)
the sooner the
original cold air
will be expelled
by the fresh
warm air

That a reason
for introducing
a good deal of
slightly heated
air rather than
a little highly
heated.

The quantity
discharged in
a given time
from a given
aperture (this
being but that
one) may be
increased
1. by the
of extra heat
produced in
the room at
different times
under different
degree of expansion
in the
gage

A horizontal tube closed
by a perpendicular plate
which on being
driven in drawn
back a spring
proportionably

To let the air
out there are
two parallel
slits one on each
side of the tube.

That the spring
may not be weakened

the heated air
the plate to which
the spring is attached

acts -

It may be either
in the same time
connected by a
stiff wire - or
at right angles
& moved by an
index -

In this way it
more sensible

The thermometer
will show without
any other instrument
the quantity
discharged in a
given time, the
degree of extra-
-heat produced being
ascertained

The thermometer
being hung at the
discharging hole
It may be hung
at the across the
mouth, or a
little way within
it.

Where, in the
trial of different
stores the rooms
are different, there
must be great intricacy
in the calculations, & consistancy
in the results. Here the
room being the
same size different
shown may
be tried necessarily
without and by
burying them, the
experiment may be
varied in more
than the above some
different ways.

If the quantity of
mercury in the thermometer
were a known
quantity, proportional the expansion
of it would
the correspondent
proportional expansion
of the air:
and by that means
the quantity of
air in a given
sphere: the degree of its rarefaction.

Suppose a gra pint
of air weights 5
grams when it is
at 50, how much
should it weigh when
at 40 and 60?

Practical use
of the above
knowledge
1. To the
1. The room being
given, one knows
the size of

to produce any
given quantity
of extra heat.
2. One knows
the quantity of
warmed air that
has been discharged

in consequence
of the given
degree of heat.
