Suppose Let Suppose now the substance designed to be impregnated body into or through which <add>this</add>
to the fluid is intended to be forced, be a log of wood: in this case either
all the whole of the log one end excepted is exposed
to the vacuum chamber The varieties, of which
the structure construction of the apparatus the conduct of the impregnation is susceptible,
may be distinguished intocomprised under two principal cases:
either the whole of the log, one end excepted, will be
within the chamber, that end only remaining exposed
to the fluid without, or the whole of it, one end excepted,
will be exposed to the fluid without, one this
one end alone being introduced within the Chamber.
In the first case the chamber must be large enough
to contain the log: in the other case there must
vessel withinindeed be without the chamber a vessel large
enough to contain the log almost encompassed together with the
fluid with which it is nearly encompassed, but
the Chambersize of the itself need be not greater than what is necessary
to enable it to receive only be of such
a size as to have one of its boundaries large enough
for the log to fit into. What the log wants of
filling up the aperture thusleft in the Chamber to
receive it must of course be filled up air-tight for
for instancein operation at each operation, by wedges of wood with a cement.
