Description | Azais presents two papers to the Royal Society. The first concerns states of matter and the causes of physical phenomena. Azais explains how external forces transform solid substances into liquids, vapours, gases and volatile fluids. The second paper follows on from the first and concerns the source of chemical action. He suggests that expansion is what moves matter, and that all the movements executed by matter arise from its essential and universal tendency to expand. He explains that the law of continuous change is the law of all bodies in the universe. Includes a covering letter dated April 1838.
