"Royal Institution, 4th May, 1852.

"My Dear Wheatstone,

"Dr. Dubois-Raymond will be making his experiments here next Thursday, the 6th, from and after 11 o'clock. I wish to let you know, that you may if you like join the select few.

"Ever truly yours,"M. Faraday."

It was indeed his wont to share with others the delight of a new discovery. Thus Sir Henry Holland tells me that he used frequently to run to his house in Brook Street with some piece of scientific news. One of these visits was after reading Bunsen and Kirchhoff's paper on Spectrum Analysis; and he did not stop short with merely telling the tale of the special rays of light shot forth by each metallic vapour, as the following letter will show. It is addressed to the present Baroness Burdett Coutts.

"Royal Institution, Friday, 17th May.

"Dear Miss Coutts,

"To-morrow, at 4 o'clock, immediately after Max Müller's lecture, I shall show Sir Henry Holland an apparatus which has arrived from Munich to manifest the phenomena of light which have recently been made known to us by Bunsen and Kirchhoff. Mr. Barlow will be here, and he suggests that you would like to know of the occasion. If you are inclined to see how philosophers work and live, and so are inclined to climb our narrow stairs (for I must show the experiments in my room), we shall be most happy to see you. The experiments will not be beautiful except to the intelligent.

"Ever your faithful Servant,"M. Faraday."

Sometimes, too, the exhibition of a scientific fact would take him away from home. Thus, when her Majesty and the Prince Consort once paid a private visit to the Polytechnic, Mr. Pepper arranged a surprise for the Royal party, by getting Faraday in a quiet room to explain the Ruhmkorff's coil – the latest development of his own inductive currents. This he did with his usual vivacity and enthusiasm, and the interview is said to have gratified the philosopher as well as the Queen.

He could not, however, escape the inroads made upon his time by correspondence. People would write and ask him questions. Once a solitary prisoner wrote to tell him, "It is indeed in studying the great discoveries which science is indebted to you for, that I render my captivity less sad, and make time flow with rapidity," – and then he proceeds to ask, "What is the most simple combination to give to a voltaic battery, in order to produce a spark capable of setting fire to powder under water, or under ground? Up to the present I have only seen employed to that purpose piles of thirty to forty pairs constructed on Dr. Wollaston's principles. They are very large and inconvenient for field service. Could not the same effect be produced by two spiral pairs only? and if so, what can be their smallest dimension?" And who was the prisoner who thus speculated on the applications of science to war? It was no other than Prince Louis Napoleon, then immured in the fortress of Ham, and now the ex-Emperor of the French. At another time he wrote asking for his advice in the manufacture of an alloy which should be about as soft as lead, but not so fusible, – a question which also had evident bearing upon the art of war; and offering at the same time to pay the cost of any experiments that might be necessary.

Often, too, the correspondents of Faraday thought that they were doing him a kindness. He says somewhere: "The number of suggestions, hints for discovery, and propositions of various kinds, offered to me very freely and with perfect goodwill and simplicity on the part of the proposers, for my exclusive investigation and final honour, is remarkably great, and it is no less remarkable that but for one exception – that of Mr. Jenkin – they have all been worthless… I have, I think, universally found that the man whose mind was by nature or self-education fitted to make good and worthy suggestions, was also the man both able and willing to work them out."

Both the askers of questions and the givers of advice expected answers – and the answers came. Most of Faraday's letters, indeed, are of a purely business character: sometimes they are very laconic, as the note in which he announced to Dr. Paris one of his principal discoveries: —

"Dear Sir,

"The oil you noticed yesterday turns out to be liquid chlorine.

"Yours faithfully,"M. Faraday."

But in other letters, as may be expected, there is found the enthusiasm of his ardent nature, or the glow of his genial spirit. An instance or two may suffice.

"Royal Institution, 24th March, 1843.

"Dear Sir,

"I have received and at once looked at your paper. Many thanks for so good a contribution to the beloved science. What glorious steps electricity has taken in the days within our remembrance, and what hopes are held out for the future! The great difficulty is to remove the mists which dim the dawn of a subject, and I cannot but consider your paper as doing very much that way for a most important part of natural knowledge.

"I am, my dear Sir,"Most truly yours,"M. Faraday.

"J. P. Joule, Esq."

"Royal Institution, 15th Oct., 1853.

"My dear Miss Moore,

"The summer is going away, and I never (but for one day) had any hopes of profiting by your kind offer of the roof of your house in Clarges Street. What a feeble summer it has been as regards sunlight! I have made a good many preliminary experiments at home, but they do not encourage me in the direction towards which I was looking. All is misty and dull, both the physical and the mental prospect. But I have ever found that the experimental philosopher has great need of patience, that he may not be downcast by interposing obstacles, and perseverance, that he may either overcome them, or open out a new path to the bourn he desires to reach. So perhaps next summer I may think of your housetop again. Many thanks for your kind letter and all your kindnesses uswards. My wife had your note yesterday, and I enjoyed the violets, which for a time I appropriated.

"With kindest remembrances and thoughts to all with you and her at Hastings,

"I am, my dear Friend,"Very faithfully yours,"M. Faraday."

The following is written to Mr. Frank Barnard, then an Art student in Paris: —

"Royal Institution, 9th Nov., 1852.

"My dear Nephew,

"Though I am not a letter-writer and shall not profess to send you any news, yet I intend to waste your time with one sheet of paper: first to thank you for your letter to me, and then to thank you for what I hear of your letters to others. You were very kind to take the trouble of executing my commissions, when I know your heart was bent upon the entrance to your studies. Your account of M. Arago was most interesting to me, though I should have been glad if in the matter of health you could have made it better. He has a wonderful mind and spirit. And so you are hard at work, and somewhat embarrassed by your position: but no man can do just as he likes, and in many things he has to give way, and may do so honourably, provided he preserve his self-respect. Never, my dear Frank, lose that, whatever may be the alternative. Let no one tempt you to it; for nothing can be expedient that is not right; and though some of your companions may tease you at first, they will respect you for your consistency in the end; and if they pretend not to do so, it is of no consequence. However, I trust the hardest part of your probation is over, for the earliest is usually the hardest; and that you know how to take all things quietly. Happily for you, there is nothing in your pursuit which need embarrass you in Paris. I think you never cared for home politics, so that those of another country are not likely to occupy your attention, and a stranger can be but a very poor judge of a new people and their requisites.

"I think all your family are pretty well, but I know you will hear all the news from your appointed correspondent Jane, and, as I said, I am unable to chronicle anything. Still, I am always very glad to hear how you are going on, and have a sight of all that I may see of the correspondence.

"Ever, my dear Frank,"Your affectionate Uncle,"M. Faraday."

His scientific researches were very numerous. The Royal Society Catalogue gives under the name of Faraday a list of 158 papers, published in various scientific magazines or learned Transactions. Many of these communications are doubtless short, but a short philosophical paper often represents a large amount of brain work; a score of them are the substance of his Friday evening discourses; while others are lengthy treatises, the records of long and careful investigations; and the list includes the thirty series of his "Experimental Researches in Electricity." These extended over a period of twenty-seven years, and were afterwards reprinted from the "Philosophical Transactions," and form three goodly volumes, with 3,430 numbered paragraphs – one of the most marvellous monuments of intellectual work, one of the rarest treasure-houses of newly-discovered knowledge, with which the world has ever been enriched. Faraday never published but one book in the common acceptation of the term – it was on "Chemical Manipulation," – but there appeared another large volume of reprinted papers: and three of his courses of lectures were also published as separate small books, though not by himself. It is very tempting to linger among these 158 papers; but this is not intended as a scientific biography, and those readers who wish to make themselves better acquainted with his work will find an admirable summary of it in Professor Tyndall's "Faraday as a Discoverer." In Sections IV. and V., however, I have endeavoured to give an idea of his manner of working, and of the practical benefits that have flowed to mankind from some of his discoveries.

As these papers appeared his fame grew wider and wider. When a comparatively young man he was naturally desirous of appending the mystic letters "F.R.S." to his name, and he was balloted into the Royal Society in January 1824, not without strong opposition from his master, Sir Humphry Davy, then president. He paid the fees, and never sought another distinction of the kind. But they were showered down upon him. The Philosophical Society of Cambridge had already acknowledged his merits, and the learned Academies of Paris and Florence had enrolled him amongst their corresponding members. Heidelberg and St. Petersburg, Philadelphia and Boston, Copenhagen, Berlin, and Palermo, quickly followed: and as the fame of his researches spread, very many other learned societies in Europe and America, as well as at home, brought to him the tribute of their honorary membership.9 He thrice received the degree of Doctor, Oxford making him a D.C.L., Prague a Ph.D., and Cambridge an LL.D., besides which he was instituted a Chevalier of the Prussian Order of Merit, a Commander of the Legion of Honour, and a Knight Commander of the Order of St. Maurice and St. Lazarus. Among the medals which he received were each of those at the disposal of the Royal Society – indeed the Copley medal was given him twice – and the Grande Médaille d'Honneur at the time of the French Exhibition. Altogether it appears he was decorated with ninety-five titles and marks of merit,10 including the blue ribbon of science, for in 1844 he was chosen one of the eight foreign associates of the French Academy.

Though he had never passed through a university career, he was made a member of the Senate of the University of London, which he regarded as one of his chief honours; and he showed his appreciation of the importance of the office by a diligent attendance to its duties.

As the recognized prince of investigators, it is no wonder that on the resignation of Lord Wrottesley, an attempt was made to induce him to become President of the Royal Society. A deputation waited upon him and urged the unanimous wish of the Council and of scientific men. Faraday begged for time to consider. Tyndall gives us an insight into the reasons that led him to decline. He tells us: "On the following morning I went up to his room, and said, on entering, that I had come to him with some anxiety of mind. He demanded its cause, and I responded, 'Lest you should have decided against the wishes of the deputation that waited on you yesterday.' 'You would not urge me to undertake this responsibility,' he said. 'I not only urge you,' was my reply, 'but I consider it your bounden duty to accept it.' He spoke of the labour that it would involve; urged that it was not in his nature to take things easy; and that if he became president, he would surely have to stir many new questions, and agitate for some changes. I said that in such cases he would find himself supported by the youth and strength of the Royal Society. This, however, did not seem to satisfy him. Mrs. Faraday came into the room, and he appealed to her. Her decision was adverse, and I deprecated her decision. 'Tyndall,' he said at length, 'I must remain plain Michael Faraday to the last; and let me now tell you, that if I accepted the honour which the Royal Society desires you to confer upon me, I would not answer for the integrity of my intellect for a single year.'"

In 1835 Sir Robert Peel desired to confer pensions as honourable distinctions on Faraday and some other eminent men. Lord Melbourne, who succeeded him as Prime Minister, in making the offer at a private interview, gave utterance to some hasty expressions that appeared to the man of science to reflect on the honour of his profession, and led to his declining the money. The King, William IV., was struck with the unusual nature of the proceeding, and kept repeating the story of Faraday's refusal; and about a month afterwards the Premier, dining with Dr. (now Sir Henry) Holland, begged him to convey a letter to the Professor and to press on him the acceptance of the pension. The letter was couched in such honourable and conciliatory terms, that Faraday's personal objection could no longer apply, and he expressed his willingness to receive this mark of national approval. A version of the matter that found its way into the public prints caused fresh annoyance, and nearly produced a final refusal, but through the kind offices of friends who had interested themselves throughout in the matter, a friendly feeling was again arrived at, and the pension of £300 a year was granted and accepted.

In 1858 the Queen offered him a house at Hampton Court. It was a pretty little place, situated in the well-known Green in front of the Palace; and in that quiet retreat Faraday spent a large portion of his remaining years.

In October 1861 he wrote a letter to the managers of the Royal Institution, resigning part of his duties, in which he reviewed his connection with them. "I entered the Royal Institution in March 1813, nearly forty-nine years ago, and, with the exception of a comparatively short period during which I was abroad on the Continent with Sir H. Davy, have been with you ever since. During that time I have been most happy in your kindness, and in the fostering care which the Royal Institution has bestowed upon me. Thank God, first, for all His gifts. I have next to thank you and your predecessors for the unswerving encouragement and support which you have given me during that period. My life has been a happy one, and all I desired. During its progress I have tried to make a fitting return for it to the Royal Institution, and through it to science. But the progress of years (now amounting in number to three-score and ten) having brought forth first the period of development, and then that of maturity, have ultimately produced for me that of gentle decay. This has taken place in such a manner as to make the evening of life a blessing; for whilst increasing physical weakness occurs, a full share of health free from pain is granted with it; and whilst memory and certain other faculties of the mind diminish, my good spirits and cheerfulness do not diminish with them."

When he could no longer discharge effectually his duties at the Trinity House, the Corporation quietly made their arrangements for transferring them, and, with the concurrence of the Board of Trade, determined that his salary of 200l. per annum should continue as long as he lived. Sir Frederick Arrow called upon him at Albemarle Street, and explained how the matter stood, but he found it hard to persuade the Professor that there was no injustice in his continuing to receive the money; then, taking hold of Sir Frederick by one hand and Dr. Tyndall by the other, Faraday, with swimming eyes, passed over his office to his successor.

Gradually but surely the end approached. The loss of memory was followed by other symptoms of declining power. The fastenings of his earthly tabernacle were removed one by one, and he looked forward to "the house not made with hands, eternal in the heavens." This was no new anticipation. Calling on the friend who had long directed with him the affairs of the Institution, but who was then half paralysed, he had said, "Barlow, you and I are waiting; that is what we have to do now; and we must try to do it patiently." He had written to his niece, Mrs. Deacon: "I cannot think that death has to the Christian anything in it that should make it rare, or other than a constant, thought; out of the view of death comes the view of the life beyond the grave, as out of the view of sin (the true and the real view which the Holy Spirit alone can give to a man) comes the glorious hope… My worldly faculties are slipping away day by day. Happy is it for all of us that the true good lies not in them. As they ebb, may they leave us as little children trusting in the Father of Mercies, and accepting His unspeakable gift." And when the dark shadow was creeping over him, he wrote to the Comte de Paris: "I bow before Him who is Lord of all, and hope to be kept waiting patiently for His time and mode of releasing me according to His Divine Word, and the great and precious promises whereby His people are made partakers of the Divine nature." His niece, Miss Jane Barnard, who tended him with most devoted care, thus wrote from Hampton Court on the 27th June: – "The kind feelings shown on every side towards my dear uncle, and the ready offers of help, are most soothing. I am thankful to say that we are going on very quietly; he keeps his bed and sleeps much, and we think that the paralysis gains on him, but between whiles he speaks most pleasant words, showing his comfort and trust in the finished work of our Lord. The other day he repeated some verses of the 46th Psalm, and yesterday a great part of the 23rd. We can only trust that it may be given us to say truly, 'Thy will be done;' indeed, the belief that all things work together for good to them that believe, is an anchor of hope, sure and steadfast, to the soul. We are surrounded by most kind and affectionate friends, and it is indeed touching to see what warm feelings my dear uncle has raised on all sides."

When his faculties were fading fast, he would sit long at the western window, watching the glories of the sunset; and one day when his wife drew his attention to a beautiful rainbow that then spanned the sky, he looked beyond the falling shower and the many-coloured arch, and observed, "He hath set his testimony in the heavens." On August 25, 1867, quietly, almost imperceptibly, came the release. There was a philosopher less on earth, and a saint more in heaven.

The funeral, at his own request, was of the simplest character. His remains were conveyed to Highgate Cemetery by his relations, and deposited in the grave, according to the practice of his Church, in perfect silence. Few of his scientific friends were in London that bright summer-time, but Professor Graham and one or two others came out from the shrubbery, and joining the group of family mourners, took their last look at the coffin.

But when this sun had set below our earthly horizon, there seemed to spring up in the minds of men a great desire to catch some of the rays of the fading brightness and reflect them to posterity. A "Faraday Memorial" was soon talked of, and the work is now in the sculptor's hands; the Chemical Society has founded a "Faraday Lectureship;" one of the new streets in Paris has been called "Rue Faraday;" biographical sketches have appeared in many of the British and Continental journals; successive books have told the story of his life and work; and in a thousand hearts there is embalmed the memory of this Christian gentleman and philosopher.

SECTION II

STUDY OF HIS CHARACTER

In the previous section we have traced the leading events of a life which was quietly and uniformly successful. We have watched the passage of the errand-boy into the philosopher, and we have seen how at first he begged for the meanest place in a scientific workshop, and at last declined the highest honour which British Science was capable of granting. His success did not lie in the amassing of money – he deliberately turned aside from the path of proffered wealth; nor did it lie in the attainment of social position and titles – he did not care for the weight of these. But if success consists in a life full of agreeable occupation, with the knowledge that its labours are adding to the happiness and wealth of the world, leading on to an old age full of honour, and the prospect of a blissful immortality, – then the highest success crowned the life of Faraday.

How did he obtain it? Not by inheritance, and not by the force of circumstances. The wealth or the reputation of fathers is often an invaluable starting-point for sons: a liberal education and the contact of superior minds in early youth is often a mighty help to the young aspirant: the favour of powerful friends will often place on a vantage-ground the struggler in the battle of life. But Faraday had none of these. Accidental circumstances sometimes push a man forward, or give him a special advantage over his fellows; but Faraday had to make his circumstances, and to seize the small favours that fortune sometimes threw in his way. The secret of his success lay in the qualities of his mind.

It is only fair, however, to remark that he started with no disadvantages. There was no stain in the family history: he had no dead weight to carry, of a disgraced name, or of bad health, or deficient faculties, or hereditary tendencies to vice. It must be acknowledged, too, that he was endowed with a naturally clear understanding and an unusual power of looking below the surface of things.

The first element of success that we meet with in his biography is the faithfulness with which he did his work. This led the bookseller to take his poor errand-boy as an apprentice; and this enabled his father to write, when he was 18: "Michael is bookbinder and stationer, and is very active at learning his business. He has been most part of four years of his time out of seven. He has a very good master and mistress, and likes his place well. He had a hard time for some while at first going; but, as the old saying goes, he has rather got the head above water, as there is two other boys under him." This faithful industry marked also his relations with Davy and Brande, and the whole of his subsequent life; and at last, when he found that he could no longer discharge his duties, it made him repeatedly press his resignation on the managers of the Royal Institution, and beg to be relieved of his eldership in the Church.

His love of study, and hunger after knowledge, led him to the particular career which he pursued, and that power of imagination, which reveals itself in his early letters, grew and grew, till it gave him such a familiarity with the unseen forces of nature as has never been vouchsafed to any other mortal.

As a source of success there stands out also his enthusiasm. A new fact seemed to charge him with an energy that gleamed from his eyes and quivered through his limbs, and, as by induction, charged for the time those in his presence with the same vigour of interest. Plücker, of Bonn, was showing him one day in the laboratory at Albemarle Street his experiments on the action of a magnet on the electric discharge in vacuum tubes. Faraday danced round them; and as he saw the moving arches of light, he cried, "Oh! to live in it!" Mr. James Heywood once met him in the thick of a tremendous storm at Eastbourne, rubbing his hands with delight because he had been fortunate enough to see the lightning strike the church tower, and displace a pinnacle.

This enthusiasm led him to throw all his heart into his work. Nor was the energy spasmodic, or wasted on unworthy objects; for, in the words of Bence Jones, his was "a lifelong lasting strife to seek and say that which he thought was true, and to do that which he thought was kind."
