PAGE 



Standard temperature of animals How maintained Production of heat by 

 Vegetables Mode of generation of animal heat Theory of combustion 

 Objections to this theory No oxidation in vegetables during production of 

 *fceat Quantities of oxygen and carbonic acid in animals do not correspond 

 with each other Production of animal heat a local process Depends on 

 the chemical phenomena of nutrition . . . 253-263
