When near the close of his life, he presented to the Royal Institution the bookcase with the volumes of notes of Davy’s lectures and of books bound by himself, the inscription recorded that they were the gift of “Michael _and_ Sarah Faraday.” Every Saturday evening he used to take his wife to her father’s house at Paternoster Row, so that on Sunday they should be nearer to the chapel at Paul’s Alley. And in after years, when he was away on scientific work, visiting lighthouses, or attending meetings of the British Association, he always tried to return for the Sunday. A letter from Liebig in 1844 (see p. 225) gives one of the very few glimpses of contemporary date of the impression made by Mrs. Faraday upon others. One month after his marriage Faraday made his profession of faith before the Sandemanian church, to which his wife already belonged, and was admitted a member. To his religious views, and his relations to the body he thus formally joined, reference will be found later. [Sidenote: FIRST ELECTRICAL DISCOVERY.] Faraday now settled down to a routine life of scientific work. His professional reputation was rising, and his services as analyst were being sought after. But in the midst of this he was pursuing investigations on his own account. In the late summer of this year he made the discovery of the electro-magnetic rotations described in Chapter III.--his first important piece of original research--and had in consequence a serious misunderstanding with Dr. Wollaston. On September 3rd, working with George Barnard in the laboratory, he saw the electric wire for the first time revolve around the pole of the magnet. Rubbing his hands as he danced around the table with beaming face, he exclaimed: “There they go! there they go! we have succeeded at last.” Then he gleefully proposed that they should wind up the day by going to one of the theatres. Which should it be? “Oh, to Astley’s, to see the horses.” And to Astley’s they went. On Christmas Day he called his young wife to see something new: an electric conducting-wire revolving under the influence of the magnetism of the earth alone. He also read two chemical papers at the Royal Society, announcing new discoveries; one of them in conjunction with his friend Phillips. In July, 1822, he took his wife and her mother to Ramsgate, whilst he went off with Phillips to Swansea to try a new process in Vivian’s copper works. During this enforced parting, Faraday wrote his wife three letters from which the following are extracts:--- [Sidenote: “A MERE LOVE-LETTER.”] (July 21, 1822). I perceive that if I give way to my thoughts, I shall write you a mere love-letter, just as usual, with not a particle of news in it: to prevent which I will constrain myself to a narrative of what has happened since I left you up to the present time, and then indulge my affection.
