Shortly after the death of Michael Faraday, Professor Auguste de la Rive, and others of his friends, gave to the world their impressions of his life, his character, and his work; Professor Tyndall drew his portrait as a man of science; and after a while Dr. Bence Jones published his biography in two octavo volumes, with copious extracts from his journals and correspondence. In a review of this "Life and Letters" I happened to mention my thought of giving to the public some day my own reminiscences of the great philosopher; several friends urged me to do so, not in the pages of a magazine, but in the form of a little book designed for those of his fellow-countrymen who venerate his noble character without being able to follow his scientific researches. I accepted the task. Professor Tyndall and Dr. Bence Jones, with Messrs. Longman, the publishers, kindly permitted me to make free use of their materials; but I am indebted to the Corporation of the Trinity House, and to many friends, for a good deal of additional information; and in compiling my book I have preferred, where practicable, to illustrate the character of Faraday by documents or incidents hitherto unpublished, or contained in those sketches of the philosopher which are less generally known.
It is due to myself to say that I had pretty well sketched out the second part of this book before I read M. Dumas' "Eloge Historique." The close similarity of my analysis of Professor Faraday's character with that of the illustrious French chemist may perhaps be accepted as an additional warrant for the correctness of our independent estimates.
