BILE. 221 



The importance of bile may be judged of from 

 the fact that our food never digests well when it is 

 too small in quantity, or its properties are changed 

 by disease. In jaundice, the bile, in place of being 

 poured into the intestines, is carried into the blood, 

 and tinges the whole body with a yellowish hue. 



There are several other glands in union with the 

 stomach and intestines. These secrete various 

 fluids, which serve some useful purpose in diges~ 

 tion.
