LAVOISIER'S EXPERIMENTS ON RESPIRATION. MADAME LAVOISIER AT THE TABLE TAKING NOTES 



Lavoisier (l 743-94), the founder of modern chemistry by his demonstration of the conversation of matter. In chemical processes 

 of all sorts there are changes in the quality of the matter, but never any change in its total quantity. He explained what breathing 

 really means the taking in of oxygen to keep combustion or oxidation agoing, and the getting rid of the waste-product carbonic acid 

 gas. He was guillotined in the Reign of Terror, the mob saying, " The Republic has no need of savants."
