THE HEASON WHY. 203 



Remove far from me poverty and lies; give me neither poverty nor riches; 

 feed me with food convenient for me." PROVERBS xxx. 



Fig. 49. SECTION OP THE STOMACH, &C. 



A. The inner coat of the stomach. (The stomach is here represented cut 

 through its length, so that wo can see its inside.) 



B. The lower extremity of the throat, or oesophagus, through which food 

 enters the stomach. 



C. The passage out of the stomach, called the pylorus, where a muscular con- 

 traction prevents the escape of undigested food. 



D. The duodenum, and the ducts through which the bile and pancreatic 

 juices enter and mingle with our food. 



876. Why do we not feel tlie food being transmitted 

 through the throat ? 



Because the nerves of the body differ in their powers : some are 

 nerves of feeling ', some of motion, and others are nerves of the 

 senses. The nerves of feeling are most abundantly distributed to 

 those parts where feeling is most useful and necessary to us. But 

 the faculty of feeling our food undergoing digestion would be no 

 service to us whatever ; therefore the nerves of motion are plen- 

 tifully distributed to the throat and stomach, but very few of the 

 nerves of feeling just as many as will tell us when we eat 

 anything too hot, or too cold, or that the stomach is out of order. 



877. Why do we feel uneasy after eating to excess? 



Because the stomach is distended, and presses upon the other 

 organs by which it is surrounded.
