This is the fourth of seven volumes of "Experimental Notes" made by Michael Faraday during the years 1820-1862; bequeathed by him to the Royal Institution of Great Britain and known today as "Faraday's Diary"; now republished for the first time since the original printing in 1936 by exclusive arrangement with the Royal Institution; includes the complete 1st edition manuscript edited by Thomas Martin with index, photographs and thousands of illustrations in Faraday's own hand. "Faraday is generally held to be one of the greatest of all experimental philosophers. Nearly every science is in his debt: and some sciences owe their existence mainly to his work. The liquefaction of gases, benzene, electro-magnetic induction, specific inductive capacity, lines of force, 'magnetic conduction' or permeability, the dark discharge, anode, cathode, magneto-optics, electro-chemical equivalent; all these terms suggest fundamental researches which he made, and many of them were called into existence in order to describe his discoveries." --Sir William H. Bragg, Director of the Laboratory of the Royal Institution (1932). Annotation A(c) 2008 The Royal Institution of Great Britain.
