Withered Fruit Restored

Take a shrivelled apple, and, placing it under the receiver, exhaust

the air. The apple will immediately be plumped up, and look as fresh

as when first gathered: for this reason, that the pressure of the

external air being taken off, the air in the apple extends it, so much

indeed that it will sometimes burst. If the air be let into the

receiver, the apple will be restored to its pristine shrivelled state.
