‎The first paper is the first appearance of one of Ampere's importent contributions to electrodynamic. This memoir was later incorporated in his great memoir of 1827 ""Mémoire sur la théorie mathématique des phénomenes electro-dynamiques...."", published 1827, the ""Principia"" of electrodynamics.The second paper is the first appearence of the paper in which Ampere describes his invention of the SOLENOID, the electro-magnetic device he used in his early electrodynamical experiments.""A solenoid is a coil wound into a tightly packed helix. In physics, the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets. The term solenoid refers specifically to a magnet designed to produce a uniform magnetic field in a volume of space (where some experiment might be carried out).""The volume contains further importent papers by Poisson ""Sur la Chaleur rayonnante"", pp. 225-246 + Note.. pp. 442-44, Gay-Lussac, Savart, Pelletier et Caventou, Becquerel etc.‎
