120 THE FUNCTION OF 



The gas of the stomach contains, besides azote and carbonic 

 acid gas, oxygen, and very little hydrogen ; while that of the 

 small intestines contains, besides the two former gases, no oxygen, 

 and abundance of hydrogen : that of the large intestines has less 

 hydrogen and carbonic acid, and likewise no oxygen. Little or 

 no gas is found in the stomach during chymification. 



The following are the results of MM. Magendie's and Che- 

 vreuirs analysis of the gases of the alimentary canal :
