WHAT IS PHYSICAL LIFE 



ical things, with this important difference, 

 that organic chemistry, i.e., that which is 

 produced by living agencies, is vastly more 

 complex in its processes than inorganic 

 chemistry. A molecule of water, for ex- 

 ample, has only three atoms in its com- 

 position, two of hydrogen, and one of 

 oxygen, but a molecule of cane-sugar has 

 forty-five atoms, and, moreover, these 

 atoms are so differently arranged in differ- 

 ent sugars that a painstaking authority 

 has written five volumes on the sugars 

 alone, and is not through with them 

 yet. 



Whatever else, therefore, may be said 

 of organic chemistry, this is certain, that 

 something enters into its processes which 

 is not found in any other chemistry, that 

 something making its products far re- 

 moved from all other chemical compo- 

 nents in the make-up of their mole- 

 cules.
