In August of 1771, Joseph Priestley
put a small branchof the mint into
a transparent closed space with
a candle that burned out the air
until it soon went out. After 27days,
he lit the extinguished candle again
and it burned perfectly well in
the air that previously would not
support it. So Priestley proved
that plants somehow change
the composition of the air.
In another celebrated experiment
from 1772, Priestley kept a mouse
in a jar of air until it collapsed.
He found that a mouse kept with
a plant would survive. These kinds
of observations led Priestley to
offer an interesting theory that
plants restore to the air whatever
breathing animals and burning
candles remove - what was later
coined by Lavoisier "oxygen".
