The Bad Effects of Imperfect Mastication. If we 



swallow food before it is thoroughly ground and mixed 

 with the saliva, the stomach and other parts of the diges-

 food to a liquid form. Further, when eating hastily, we 

 are very apt to eat too much. Thus we may give the 

 stomach a double amount of material to handle, and the 

 material may not be half so well prepared as it should 

 be. The work thus thrown upon the stomach may easily 

 be made fourfold. Of course the organs suffer, and, 

 sooner or later, if this treatment is continued, they must 

 break down.

 but the whole process of digestion, goes on better when 

 the body and mind are at rest and in a peaceful and con-

 thoughts of one's occupation, and especially all anxiety, 

 should be absolutely dismissed from the mind. For those 

 whose digestion is not strong, it is especially desirable to 

 secure a period of rest after each meal, taking a lounge 

 or easy-chair, closing the eyes, and, as nearly as possible,

 food is already half digested." 



Deliberation in Eating. It is said that the people of
