1

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

2

The quatity 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.

or other fewel employ'd
in the steam -

given quantity of water

The expansionproduction of
the total shouldshould as sudden
be as quick as possible
that the 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 height
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?

Have a row of

III above another with the closed projecting out at the side wall of the building rarefaction house iV V 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 obindirer 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 opun this plan have somewhat the appearance of a mushroom, as a glass drinking with a hollow stem. Pillars however may be necessary to support the circumference. These pillars may be hollow.
