"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."
