1

The quantity of
fewel that will produce
the greatest
quantity of heat

2

The quantity of
heat that will be
produced by a
given quantity
of a given sort
of fewel:i:e:
the number of
degrees that the
thermometer will
be raised by it

3

The degree of expansion
that the
air will receive
from being receiving and
broughtto a given degree
of heat as measured
by the thermometer

4

The best means of
getting rid of the
burnt air after
each blaze

5.

The quantity of coals
or other fewel employ'd
in the steam -
-engine to raise a
given quantity of water

The expansion production of
the heat should should as sudden
be as quick as possible
that there heat
may be may
not be time for
the walls of the
building to take
the heat from
the air included
air till the fullest
effect of the
heat in producing
rarefaction expansion
has been produced.

Quere how to shew
when the water
has got to the
greatest heigth
it can be carried
to by a blaze
that has been
just made, in
order that the
sluice door may
then be shut and
the port holes for
letting out the
water opened?

glass tubes one

That no water
may be collected
in waste, so much
of the column
as is below the
lowest mark from
which the water
can produce its
effect may be
much obside
than the rest,
by this means a
given degree of
expansion in the
whole body of
air will give
room for the water
to ascend to a
greater heighth
The rarefaction
house will upon
this plan have
somewhat the
appearance of
a mushroom, or
a drinking glass with a
hollow stem.

Pillars however
may be necessary
to support the
circumference.
These pillars may
be hollow.

The water which
is below the mark
may be employ'd
as often as the
rarefaction house
is emptied be
employ'd in running
the other half
