a degree somewhat higher than the lowest at which
the fluid liquid can be made to distill in vacuo
to a degree any thing less than that which would
cause the vapour of the liquid to burst the still.
For this purpose concerning the contents of the still

8. Regulation of heat.- By the process of distillation when performed
carried on in vacuo a means is afforded of producing
a balneum in which any degree of heat may
be maintained at pleasure and for any length of
time, from a degree somewhat higher than the lowest at which the liquid can be
made to distil in vacuo in the highest temperature
natural to the place up to a degree any thing less
than that which would cause the vapour of the liquid
(whatever it be) to burst the still. For this purpose,
conceiving the contents of the still (whether the liqud
or the vapour or both together) to constitute the balneum, nothing
more is necessary than to stop the escaping of the vapour
out of the still into the condenser by a valve, so loaded by
determinate weights or other means as to confine the vapour till it
has acquired the intended degree of heat.
