The ox of 1,500 pounds weight consists chemically of the 

 following substances: 



fcs oz. 



Oxygen •. 1080 



Hydrogen 140 



Carbon 209 



Nitrogen 36 



Phosphorus 11 6 



Calcium 20 



Sulphur 5 



Chlorine 1 5 



Sodium 1 7 



Iron . . iy 2 



Potassium . . 6^ 



Magnesium . . ^ 



Silica 1 20 grains. 



The oxygen is combined with the phosphorus to make phos- 

 phoric acid; with the calcium to make lime; with the sodium to 

 make soda; with the magnesium to make magnesia, and with 

 the potassium to make potash. 



Now, if we add the oxygen and hydrogen together we have 

 what? 1,220 pounds of water as one of the component parts 

 of the 1,500-pound ox. The phosphoric acid is combined with 

 the lime to make phosphate of lime, of which the solid parts of 

 the bones are made; the chlorine is combined with the sodium 

 to make common salt. The oxygen, hydrogen, carbon, nitro- 

 gen and sulphur are combined to form the fibrine of the flesh; 

 the albumen of the blood (or that part which forms the clot) and 

 the gelatine of the bones; the oxygen and hydrogen are com- 

 . bined to form the water, of which nearly 1,100 pounds of the 

 1,500 are composed; and the carbon, hydrogen and oxygen are 

 combined to form the fat.
