First appearance of this milestone paper in which Faraday announces his discovery of the laws of electrochemistry, which today bears his name. The first law states that the quantity of electrochemical change is proportional to the quantity of electricity involved. (Sections 373-377), or in other words that there is a certain absolute quantity of the electric power associated with each atom !!. In the paper offered he further announces his proof, that the 2 kinds of electricity, frictional (resinous) and voltaic (vitrious) are identical. "...in 1833 he succeeded in showing that every known effect of electricity - physiological, magnetis, luminous, calorific, chemical and mechanical - may be obtained from indifferently either witt the electricity which is obtained by friction or with that obtained from a voltaic battery. henceforth the identity of the two was beyond doubt."(Whittaker p. 175.).

From 1831 to 1852 Michael Faraday published his "Experimental Researches in Electricity" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other.
