should be drawn between the action by which
the chest is mechanically filled with air by
its alternate expansion and contraction and
that physiological process and its immediate
results, which depend on the amount and
degree with which the oxygen combines with
the blood in the lungs after the atmosphere
has been brought into contact with it through
the muscular influences provided for that
purpose. The action of the fly-wheel of
a watch may be essential in order to set free
at proper intervals the motive force of the main=

fly wheel which puts the whole chain of events
into operation nor indeed which sustains the
movements of the fly-wheel itself.
It has been asserted by a modern author of
some little celebrity that the air, which is breath=

of the food, necessary for the animals consump=

according to this theory, the lungs can be no=
