15 Exhaustive
Thermometers for example, may be filled almost instantaneously
to as great a degree of accuracy as they usually are by any of the
customary & tedious means. For this purpose the tubes may be
place perpendicularly in a vessel of sufficient capacity to contain
them, supporting them by means of a grating or net work,
then the chamber may be exhausted & the mercury or sprits admitted
to the vessel containing the the tubes by means of a stop cock;
so at to cover the orifices of the tubes, there being no improvement
from air contained in them the fluid will fill them instanta-
neously excepting the very small portion of air & water
that an air pump is found incapable of exhausting which may
be afterward taken away by the usual means.
