4. The fat is carried to the lungs, and is there oxidized 



to carbonic acid gas and water, each ounce of fat 

 using nearly three ounces of oxygen. 



5. The gluc6se is carried to the liver, and from there is 



given out in a steady stream and oxidized to car- 

 bonic acid gas and water, each ounce using a little 

 more than an ounce of oxygen. 



6. The peptone is carried to the liver, and there is 



changed back to the form of albumin adapted to 

 the blood and tissues of the body. 



7. In the liver some albumin is oxidized, and the rest is 



sent out as a part of the blood to feed the cells. 



8. Poisons are often absorbed with the food, and are 



carried to the liver. But the liver cells separate 

 out the poisons, and either destroy them or expel 

 them with the bile. 



9. By intemperate eating the stomach is disordered. 



Then more work is put upon the intestine, until 

 it fails in its duties. Then the liver has imper- 

 fectly digested food and more poisons to take care 

 of. Then a poor quality of bile is poured out. 

 Then the intestine fails still more in its work. So 

 the circle of cause and effect goes on, all depending 

 at first upon intemperate eating. 



10. The last act of digestion, or the expulsion of waste 

 matters, should be attended to regularly every day. 



DEMONSTRATIONS 



48. Show the absorption of food in a young kitten or puppy 

 which had been fed with cream about two hours before being killed. 

 Place the animal in a tight box along with a sponge containing half 

 an ounce of chloroform. In a few moments the animal will be dead. 

 At once open its abdomen and spread out its intestine. Across its 

 fanlike mesentery will be seen white lines. These are lacteals, which
