Traité élémentaire de chimie t. 1 (1789)
43. The New Chemistry
Traite Elementaire De Chimie was a decisive move in the final overthrow of alchemy and the phlogiston theory introduced by Stahl a century earlier. By the use of the balance for weight determination at every chemical change and the building of a rational system of elements, Lavoisier laid the foundation of modern chemistry. He introduced a modern definition of element and compound, explained burning and rusting as a chemical system. His concepts of the principles of the indestructibility and conservation of matter guided him in formulating his methods of organic analysis. He was a victim of the excesses of the French Revolution, but his work remains immortal.
