EDME, a natural philosopher, was born in Burgundy in the seventeenth century. During part of his life he dwelt at Dijon, and from that place his first works are dated. He had studied for the church, and was afterwards chosen prior of St Martin, near Beaune. On the formation of the Academy of Sciences he became one of its members. He died in 1684. Mariotte was among the first French philosophers who turned their attention to experimental physics. In 1717 there was published at Leyden, in 2 vols. 4to, a collection of his works, comprising Treatises on Vegetation, on the Nature of the Air, on Heat and Cold, on the Nature of Colours, on Hydraulics, on a New Discovery touching the Sight, on Levelling, on the Motion of the Pendulum, on the Colours and Congelation of Water, and on Logic. (For an account of Mariotte's experiments on the density of the air, see Dissertation Fithk, ii. 2.)
