It was at about this time that another incident occurred which illustrates Faraday's absolute integrity of character--integrity that would not wink at anything that was in the slightest degree not straightforward, even though it was against his own interest, which, indeed, rather shunned doing a good deed that might seem dictated by mere self-interest. His brother was working at the time as a gas-fitter, and there was a possibility of his getting the Athenæum Club work in connection with his trade. Michael, writing on the subject, said, "Few things would please me more than to help my brother in his business, or than to know that he had got the Athenæum work; but I am exceedingly jealous of myself, lest I should endeavour to have that done for him as my brother which the Committee might not like to do for him as a tradesman, and it is this which makes me very shy of saying a word about the matter." During these years Faraday was getting through a vast quantity of work, his experimental researches in electricity were taking up a great part of his time, but other matters were not neglected. He was frequently lecturing before the Royal Institution or the Royal Society; while he wrote a large number of scientific papers for the various philosophical periodicals to which he contributed. Besides presenting series after series of his brilliant _Experimental Researches_ to the Royal Society, he had also to attend to his lectures at Woolwich, and his work for the Trinity House. He must indeed, hard-working man that he was, have found his long day very fully occupied; and it is scarcely to be wondered at that in 1839 the strain began to tell upon him, and a period of rest became necessary. As years went on, such periods of rest were more frequent and yet more vitally important. In 1837 the British Association[8] held its Annual Meeting at Liverpool, and Faraday attended it, and was made, as he put it, "a most responsible person," President of the Chemical section. From Liverpool he wrote home to his wife, "To-day I think we made our section rather more interesting than was expected, and to-morrow I expect will be good also. In the afternoon Daniell and I took a quiet walk; in the evening he dined with me here. We have been since to a grand conversazione at the Town Hall, and I have now returned to my room to talk with you as the pleasantest and happiest thing I can do. Nothing rests me so much as communion with you. I feel it even now as I write; and I catch myself saying the words aloud as I write them, as if you were within hearing. Dear girl, think of me till Saturday evening. I find I can get home very well by that time; so you may expect me. "Ever, my dear Sarah, your affectionate husband, "M. FARADAY."
