Long, long after this event, Dr. and Mrs. Faraday, with Dr. Tyndall, were returning one evening from Mr. Gassiot's, on Clapham Common: a dense fog came on, and they did not know where they were. The two gentlemen got out of their vehicle, and walked to a house and knocked. A man appeared, first at a window and afterwards at the door, very angry indeed at the disturbance, and demanded to know their business. Faraday, in his calm, irresistible manner, explained the situation and their object in knocking. The man instantly changed his tone, looked foolish, and muttered something about being in a fright lest his house of business was on fire.

As to simplicity of character: when, in the course of writing this book, I have spoken to his acquaintances about Faraday, the most frequent comment has been in such words as, "Oh! he was a beautiful character, and so simple-minded." I have tried to ascertain the cause of this simple-mindedness, and I believe it was the consciousness that he was meaning to do right himself, and the belief that others whom he addressed meant to do right too, and so he could just let them see everything that was passing through his mind. And while he knew no reason for concealment, there was no trace of self-conceit about him, nor any pretence at being what he was not. To illustrate this quality is not so easy; the indications of it, like his humour, were generally too delicate to be transferred to paper; but perhaps the following letter will do as well as anything else, for there are few philosophers who could have written so naturally about the pleasures of a pantomime and then about his highest hopes:—

"Royal Institution, London, W.

"1st January, 1857.

"My dear Miss Coutts,

"You are very kind to think of our pleasure and send us entrance to your box for to-morrow night. We thank you very sincerely, and I mean to enjoy it, for I still have a sympathy with children and all their thoughts and pleasure. Permit me to wish you very sincerely a happy year; and also to Mrs. Brown. With some of us our greatest happiness will be content mingled with patience; but there is much happiness in that and the expected end.

"Ever your obliged Servant,

"M. Faraday."[14]

As to truthfulness: he was not only truthful in the common acceptation of the word, but he did not allow, either in himself or others, hasty conclusions, random assertions, or slippery logic. "At such times he had a way of repeating the suspicious statement very slowly and distinctly, with an air of wondering scrutiny as if it had astonished him. His irony was then irresistible, and always produced a modification of the objectionable phrase."

One Friday evening there was exhibited an improved Davy lamp, with an eulogistic description. Faraday added the words, "The opinion of the inventor."

"An acquaintance rather given to inflict tedious narratives on his friends was descanting to Faraday on the iniquity of some coachman who had set him down the previous night in the middle of a dark and miry road,—'in fact,' said the irksome drawler, 'in a perfect morass; and there I was, as you may imagine, half the night, plunging and struggling to get out of this dreadful morass.' 'More ass you!' rapped out the philosopher at the top of his scale of laughter." This was a rare instance, for it was only when much provoked that he would perpetrate a pun, or depart from the kind courtesy of his habitual talk.

That he was quite ready to give up a statement or view when it was proved by others to be incorrect, is shown by the Preface to the volumes in which are reprinted his "Experimental Researches." "In giving advice," says his niece Miss Reid, "he always went back to first principles, to the true right and wrong of questions, never allowing deviations from the simple straightforward path of duty to be justified by custom or precedent; and he judged himself strictly by the same rule which he laid down for others."

These beauties of character were not marred by serious defects or opposing faults. "He could not be too closely approached. There were no shabby places or ugly comers in his mind." Yet he was very far from being one of those passionless men who resemble a cold statue rather than throbbing flesh and blood. He was no "model of all the virtues," dreadfully uninteresting, and discouraging to those who feel such calm perfection out of their reach. His inner life was a battle, with its wounds as well as its victory. Proud by nature, and quick-tempered, he must have found the curb often necessary; but notwithstanding the rapidity of his actions and thoughts, he knew how to keep a tight rein on that fiery spirit.
