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 200_l._ 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.
