This is the first edition of the collected works of Father Mariotte who was a physicist and Roman Catholic priest. He performed numerous experiments to elucidate nature of heat, cold, light, sight, color, water. His papers on hydrostatics and hydraulics confirmed Torricelli's work on outflow speed of fluids and demonstrated flow resistance in supply pipes. A major contribution is that he discoveredindependently of Boyle that the volume of a gas varies inversely as the pressure, going further than Boyle in noting that this inverse relation holds only for constant temperature. He also investigated laws of impact between elastic bodies and invented apparatus to verify them. Noted for invention of laboratory equipment such as Mariotte's tube.
