These Elements of Chemistry are divided into two main parts, one being an exposition of contemporary chemical theories, and the second containing a treatise on the 5 elements: fire, air, water, earth and "menstrua" (liquids capable of liquefying a solid). It is in this part that the author expounds his chemical theory to which Voltaire would refer and whose work and importance he placed alongside Newton's astronomical works. The latter had planned to establish a synthesis of it which he never completed.
