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.

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.
