      So the letter continues, tracking Faraday’s run home to Weymouth Street, with thoughts of inclined planes, slipping and friction (prompted by the sloping pavement), the velocity and momentum of falling bodies (the rain), and the identification and naming of cloud types – cirrus, cumulus, stratus, nimbus, all then newly-coined terms – suggesting that he and Abbott may that very day have been talking about them.

      Between the scientific experiments, discussions and letter writing, Faraday and Abbott went to fireworks concerts together at the New Ranelagh Gardens in Millbank, and, in mid-August, on a trip with Robert Faraday to see ‘where the Surrey canal passes by locks over the hill’.14 With John Huxtable, another friend from scientific discussions, Faraday went ‘down the river to the Botanical Gardens at Chelsea belonging to the Company of Apothecaries. I was very pleased with the excursion,’ he wrote to Abbott, ‘and wished for you two or three times.’15 On another boating excursion they banged up against Battersea Bridge and nearly sank in a strong tide. Abbott was one of the passengers, and remembered how Faraday had not panicked like the others, and showed ‘remarkable presence of mind’.16

      One subject that exercised Faraday and Abbott in their letters was more metaphysical than the rest. Faraday mused about the development of ideas, and offered proof to Abbott that they were formed in the head.17 He told a story of how, when he was an errand boy, he had once knocked on the door of a gentleman’s house and stuck his head through the railings while waiting for an answer. What was ‘that’ side of the railings; what was ‘this’? He decided that the place where his head was was the place where he and his thoughts were, ‘for there was my perception, my senses’. Then the door opened and made him jump, and he banged his nose. From this Faraday learned a lesson: ‘it did more in illustrating the case to me than all the arguments I have heard since on the subject or all the affirmations that have been made’. What he understood was that the lesson he learned, and the opinion he had reached, was as the result of direct experience.

      The correspondence continued for nearly ten years until it petered out in the early 1820s as Faraday had less and less time to write such letters, and as his successes in science rapidly outstripped Abbott’s. Faraday was always the driving force behind the correspondence. He showed a clear desire to control its pace, and he considered his time to be more valuable than Abbott’s. ‘I wish,’ he asserted,

      to make our correspondence a deposit of Philosophical facts & circumstances that will perhaps tend to elucidate to us some of the laws of nature. For this reason I shall insert in the form of Queries or otherwise all the facts I can meet with that I think are as yet unexplained. They will be as subjects for investigation, and if you think fit to chime in with my fancy and will propose such things as you are acquainted with that are yet unresolved, or anything else that your better judgement may choose, it will give a peculiar feature to our communications and cannot fail of laying under the obligations of your most Obedient … Do not delay to inform me at all times as early as convenient, and let me caution you not to wait for my answers. Consider the disparity between your time and mine, and then if you do feel inclined to communicate alternately I hope you will give that notion up.18

      Lack of time, or his perception of its lack, is another leitmotif in Faraday’s life. Throughout his correspondence he writes of how little time he has, how easily wasted it is, how he regrets he cannot do this or that because he does not have the time, until it becomes a litany. The letter to Abbott of 2 and 3 August 1812 opens with a riddle which examines this lifelong obsession:

      What is the longest, and the shortest thing in the world: the swiftest, and the most slow: the most divisible and the most extended: the least valued and the most regretted: without which nothing can be done: which devours all that is small: and gives life and spirits to every thing that is great?

      It is that, Good Sir, the want of which has till now delayed my answer to your welcome letter. It is what the Creator has thought of such value as never to bestow on us mortals two of the minutest portions of it at once. It is that which with me is at the instant very pleasingly employed. It is Time.

      And so the correspondence continued through the summer of 1812; ten long letters, mostly heavily cross-written, from Faraday to Abbott survive between July and the end of September. Faraday was genuinely fond of Abbott, describing him on one envelope as

      An honest man close buttoned to the chin

      Broad cloth without, and warm heart within.19

      In this same period, besides the home-made experiments, the arguing about correspondence procedure, the trips to Ranelagh Gardens, to Chelsea Botanic Gardens and the Surrey Canal, and the differing interpretations of scientific evidence, Faraday gazed at the stars through an astronomical telescope, and

      had a very pleasing view of the Planet Saturn … through a refractor with a power of ninety. I saw his ring very distinctly. ’Tis a singular appendage to a planet, to a revolving globe and I should think caused some peculiar phenomenon to the planet within it. I allude to their mutual action with respect to Meteorology and perhaps Electricity.20

      And the same night he saw Venus, ‘amongst your visible planets – tis – a – beautiful – object – certainly’.

      This was the end of a wet but golden summer for Faraday, the final weeks before he came of age on 22 September, and, barely a fortnight later, when he came to the end of his apprenticeship with George Riebau. Perhaps preparing for this change of station, and doing a small redecorating job for his mother, he had set to work on 1 October hanging wallpaper at home, when a long letter arrived from Abbott full of scientific questions, which made him put away ‘cloths, shears, paper, paste and brush all’. His answers to Abbott reflect light-heartedly on the tone and friendship of the letters, and speak volumes for the quantity of information that passed between them. One by one, Faraday attends to thirteen or so unanswered questions:

      – no – no – no – no – none – right – no Philosophy is not dead yet – no – O no – he knows it – thank you – ’tis impossible – Bravo.

      In the above lines, dear Abbott you have full and explicit answers to the first page of yours dated Septr 28.21

      By this time, Faraday had finished writing up and binding the fair copy of the notes he had taken from Humphry Davy’s lectures in the spring. He had them ready to show Abbott on 12 September,22 as a prelude and an encouragement before taking the plunge and sending them to Sir Humphry. Riebau had suggested this course of action at the beginning of the summer, and now that Faraday looked at the product, with its half-calf leather binding and gold tooling, riffled through the pages heavy with ink and with his own effort, heard and felt the cover board close with a satisfying flop when he let it fall shut, he rejoiced in his works. Nevertheless, a certain depression and sense of reality began to settle on him. He warned Abbott that he was on a short fuse: ‘at present I am in as serious a mood as you can be and would not scruple to speak a truth to any human being, whatever repugnance it might give rise to’.23

      He wrote to John Huxtable in much the same tone.24 A reason for this was that his apprenticeship had expired, and he had just taken up a new position as a bookbinder with Henry de la Roche, of King Street, Portman Square, for one and a half guineas a week, that is thirty-one shillings and sixpence.25 De la Roche had a hot temper, ‘a very passionate disposition’, as Silvanus Thompson describes it,26 and Faraday was bitterly unhappy working for him. He wanted to leave ‘at the first convenient opportunity, despite the reasonable salary, ‘indeed, as long as I stop in my present situation (and I see no chance of getting out of it just yet), I must resign philosophy entirely to those who are more fortunate in the possession of time and means’.27

      When Faraday wrote this he understood Sir Humphry Davy still to be in Scotland with his wife. The Davys had, indeed, expected to be away from London until December,28 but the French scientist André-Marie Ampère had written to Sir Humphry from Paris with some astounding news, and this had drawn the Davys home early. Ampère, known now as a pioneer of electricity, told Davy of a new discovery that
