were the days in which he wrote up his notes to lectures, both Davy’s and Tatum’s, following the practice he had established when he first began to transcribe from Tatum. During those lectures he had taken down key words, ‘short but important sentences, titles of the experiments, names of what substances came under consideration’, and so on. At home, he made a second set of notes, ‘more copious, more connected and more legible than the first’. Then came a third draft, using the previous notes to write out the lecture ‘in a rough manner. They gave me the order in which the different parts came under consideration and in which the experiments were performed and they called to mind the most important subjects that were discussed.’

      Finally, there was a fourth draft:

      I then referred to memory for the whole of the lecture. It is not to be supposed that I could write it out in Mr Tatum’s own words. I was obliged to compose it myself but in the composing of it I was aided by the ideas raised in my mind at the lecture and I believe I have (from following my pattern as closely as I could) adopted Mr Tatum’s style of delivery to a considerable degree (perhaps no great acquisition).5

      Four drafts to get the flow and the style right seems to reflect an obsession, but an urgency to learn and to improve himself drove Faraday, and led him to develop practices which matched his temperament and sought out his weaknesses. It was an extraordinary achievement for a boy from the back of a blacksmith’s shop, who had taken his own steps to improve his rudimentary education, and who desperately wanted to cling on to the coat-tails of hurrying knowledge and to find the key to an understanding of nature.

      Over these same days Faraday wrote an appreciation of Humphry Davy which goes to the heart of what it was in Davy that made crowds flock to hear him, and made him a pivotal figure in the history of the public understanding of science. With a light touch of his pen, describing Davy’s peroration at the end of his final lecture at the Royal Institution, Faraday also reveals the depths of his own admiration and longing:

      Sir H. Davy proceeded to make a few observations on the connections of science with other parts of polished and social life. Here it would be impossible for me to follow him. I should merely injure and destroy the beautiful and sublime observations that fell from his lips. He spoke in the most energetic and luminous manner of the Advancement of the Arts and Sciences. Of the connection that had always existed between them and other parts of a Nation’s economy. He noticed the peculiar conjeries [sic] of great men in all departments of Life that generally appeared together, noticed Anaximander, Anaximene, Socrates, Newton, Bacon, Elizabeth &c, but by an unaccountable omission forgot himself, tho I will venture to say no one else present did. During the whole of these observations his delivery was easy, his diction elegant, his tone good and his sentiments sublime. MF.6

      By another in the sequence of lucky gusts of wind that were now impelling him, somebody, an unknown gentleman who may have come into Riebau’s shop, gave Faraday an idea. He talked about the correspondences he was having, about letters he had received from Sicily and France, and ‘within the space of half an hour’ affirmed enthusiastically that letter writing was one of the ‘purest enjoyments of his life’.7 This was how Faraday put it in a letter to Benjamin Abbott, one of the young men he had made friends with at Tatum’s science lectures, suggesting that they take up a correspondence together, and send each other letters describing their work, interests and discoveries in science. The conversation with the unknown man was, in fact, only one of the prompts that led to the long correspondence with Abbott; it was a practice also advised by Isaac Watts, the author of The Improvement of the Mind, a book which Faraday was now beginning to read closely.

      Faraday first came across The Improvement of the Mind at Riebau’s shop: it was one of the best-known and most widely read text books of the late eighteenth and early nineteenth centuries, and over Faraday’s years with Riebau many copies must have passed through his hands for binding and selling. Watts’s book is a student’s guide to study, to the attainment of knowledge, and to the means of learning. Dr Johnson had known the book well, and wrote of it: ‘Few books have been perused by me with greater pleasure … Whoever has the care of instructing others may be charged with déficience in his duty if this work is not recommended.’8

      Faraday found a passage in Watts that urged young people to write letters to each other: ‘A very effectual method of improving the mind of the person who writes, & the person who receives,’ he affirmed to Abbott.9 ‘I have concluded that letter writing improves; first, the hand writing, secondly the –’

      At this point Faraday put his pen down with a sigh. Despite his flow of enthusiasm for letter writing, he had had a sudden memory blackout. Such temporary bouts of amnesia would come to afflict him throughout his life, and over the years would bring three unbidden furies to his doorstep: frustration, depression and anger. He paused, thought, and began to write again: ‘I have the Idea I wish to express full in my mind, but have forgot the word that expresses it; a word common enough too: I mean the expression, the delivery, the composition, a manner of connecting words.’ Then the thread came back to him: ‘Thirdly it improves the mind, by the reciprocal exchange of knowledge. Fourthly, the ideas; it tends I conceive to make the ideas clear and distinct … Fifthly, it improves the morals …’

      In this roundabout way Faraday suggested to Abbott that they begin their correspondence. Finally revealing the true reason, and revealing also a single-mindedness that, behind all his scientific and spiritual works, came to drive his life, Faraday adds in terms that read like the logical steps in an experimental process: ‘MF is deficient in certain points, that he wants to make up. Epistolatory writing is one cure for these deficiencies. Therefore MF should practice Epistolatory writing.’

      A correspondence now took off in earnest. The young men met during the week to discuss science, and in the evenings wrote to each other with detailed descriptions of what happened when they did this experiment or that. Speeding back and forth between Weymouth Street and Abbott’s house in Long Lane, Bermondsey, the letters carried details such as Faraday’s observations on ‘the peculiar motions of Camphor on water’,10 or Abbott’s electrical experiments.11 Their tone is enthusiastic and breathless, inclusive, engaging and full of good will and enjoyment of the revelations that science was giving to them both. They reflect on conversations at Bermondsey which drew in other members of Abbott’s family. Abbott’s brother Robert had ‘a friendly controversy’ with Faraday about Noah’s Flood, and whether it had covered the earth entirely. Robert Abbott ‘opposed it’, but Faraday appears to have wavered – his Sandemanian influences urging him to take the biblical account literally, his instincts as a young natural philosopher, however, keeping him sceptical, rational, scientific: ‘I cannot say I maintained it but thought it was so. If your Brother has no objection to lay down his arguments on paper and will transmit them to me by Post I shall not forget the obliging condescension on his side and the gratifying honor on my own …’.12

      Only one side to the correspondence survives, because while Abbott kept the letters he had received from his friend, Faraday, in one of his later bouts of clearing out, destroyed all his letters from Abbott. But Faraday’s letters give a clear view of his activities in this formative period of his life, of the way his understanding of science developed, of his feelings and of the chronology of events. They also echo his youthful voice, vibrant with excitement, particular and clear in its expression, and we hear through the text the timbre and pace of his speech. The sentence structure suggests that he spoke at speed, making pauses for breath within his sentences, and placing the emphases at their end. With every paragraph he wants to share what he has discovered, finding it impossible to keep his knowledge to himself. Running home in the rain one Sunday evening in July after a day spent in Bermondsey with the Abbotts, Faraday found ideas and impulses coursing through his mind, and he wrote them all down for Abbott:

      I … did not stop until I found myself in the midst of a puddle and quandary of thoughts respecting the heat generated by animal bodies by exercise. The puddle however gave a turn to the affair and I proceeded from thence deeply immersed in thoughts respecting the resistance of fluids to bodies precipitated into them … My mind was deeply engaged on this subject … when it was suddenly called to take care of the body by a very cordial affectionate & also effectual
