RESPIRATION. 



[CHAP. xxix. 



The great objects of respiration are, first, the introduction of 

 oxygen, by which the products resulting"" from the disintegration of 

 tissues are converted into compounds, which are easily eliminated 

 from the body by the different organs of secretion ; and, secondly, 

 the removal of the most important and most destructive of these, 

 carbonic acid, at the pulmonary surface. 



Upon the subjects discussed in the present chapter, reference may be 

 made to the following works: Article "Respiration," by Dr. John Reid,
