The degree of heat is in

The elasticity of a quantity of air is
as the degree of its heat: its degree of heat
is therefore as its elasticity: the either one being
given known the other is known likewise.

Its elasticity may be known by the force
with which it strikes acts against any body
which is opposed to it: for instance a
valve which is closed by a spring like
that of a spring steel-yard.

Adapt Close the aperture Adapt then
such a spring to the closing of the valve
in such a manner that the utmost degree
of heat which can be given shall not but just enable
it to effect a compleat aperture (so as
to afford no more resistance to the efflux
of the air than if there were no valve
at all) and the instrument apparatus will indicate
the degree of elasticity, the corresponding
degree of heat, and the quantity of air
so heated that issues at a given time.

The force with which the air strikes upon
the valve will be indicated as in the spring
steel-yard by lines corresponding to pounds & ounces.
