ments. Think, for example, of sugar, alcohol, glycerine, 

 kerosene oil, starch, benzine, paraffin and fat. How unlike 

 they are! In spite of their apparent differences, all these 

 substances are made of carbon, hydrogen and oxygen; each 

 one contains these three and nothing more; they differ only 

 in the various proportions of the elements. In a similar 

 way, by varying the amount of each element put into 

 any combination, all the different substances in the world 

 are made from the eighty-one elements. This is true 

 of animals as well as of all other material things. The fact 

 that the body weighs just as much immediately after as it 

 does before death, shows that no substance is lost at death. 

 There is really no difference between dead-weight and live- 

 weight; clearly then the same elements enter into living and 

 dead bodies.
