COMPOSITION OF ANIMALS 



hydrates are formed of carbon, hydrogen, and oxy- 

 gen ; the last two elements are in the proportion to 

 form water, hence the name. When all the plant 

 constituents are grouped together the five divisions 

 are as follows: 



1. Water. 



2. Ash. 



3. Protein. 



4. Fat. 



5. Carbohydrates.

From the plant is fed the animal; from the animal is sustained the soil: 

 from the soil and air is nourished the plant.
