for example by weight or the reaction of a spring
to the exit of the steam, the steam willcan no longer
force itself out by the degree of elasticity it
had acquired by the quantity of uncombined heat it had possessed
before:by its former degree of heat: it is confined by the pressure resistance of
the valve all it has obtained the further degree
of heat necessary to enable it to surmount that resistance:
and thus by regulating the pressure upon
the valve the quantitydegree of heat within the still
may be regulated at pleasure till it arise to such
a pitch as to produce a degree of elasticity enough sufficient
to burst the vessel.

One A use that may be made of this means
of maintaining a constant or otherwise regulated
degree of heat is the preserving of machines such
as time keepers from of which in the motion of
which the utmost degree of regularity is of importance
(such as timekeepers) from everyany suchvariation
in the degree of heat as could affect theby which the regularity
of their motions could be effected.

In the case the time keeper or other machineAnother use may perhaps be that of tempering metals
may be included in an interior exhausted chamber and
that interior in an exterior one in which the heat
is thus regulated by steam from a boiling fluid: the operation of
winding up may be performed through an airtight
-collar.
