(4), 1-112 a. pp. 225-336 a. 2 folded engraved plates. (Entire issues offered).. Ampère's papers: pp. 88-106 + pp. 313-333 The plates depicts experimental arrangements and Ampère's initial Rotation Apparatus.
Fisrt edition and first printings of the demonstrations of Ampere's new Equilibrium technique. When Faraday had completed his importent paper on Electro-magnetic motions he send it to Ampere.. Ampere invented the Rotation Apparatus in order to repeat Faraday's experiment on the electro-magnetic rotation. He produced an uninterrupted rotation, either of magnetic pole around a wire or of a wire around a magnetic pole. From these experiments originated a new theory of electricity and magnetism. .
