the introduction of water or oxygen into the cell. In fact the energy set 
free during the union of oxygen with the liberated carbon is probably the 
main source of all the energy manifest in organic life. This carbon- 
dioxide passes away from each cell concerned, and this, together with the 
introduction of oxygen to the cell, constitutes the process known as 
respiration. Eespiration is not a process separate and distinct from the 
other metabolism of the cell. In following the course of evolution from 
simple organisms to more complex all the steps leading towards complexity 
of structure are intimately bound up with the devices by which oxygen is 
introduced into the living cells and carbon-dioxide removed from them.
