During the last decade of his life Dr. Chambers withdrew somewhat from public speaking outside of his own pulpit. About four years before his death came a stroke of paralysis which somewhat weakened him. His physician was the celebrated specialist and author who, like Dr. Oliver Wendell Holmes, has enriched both science and literature. Dr. S. Weir Mitchell. The patient was particularly touched by the tender solicitude of his Quaker friends, whose meeting house on Twelfth street was just across from his home. On recovery he sent out to his host of enquiring friends a circular containing his thanks in print as follows: A CARD FROM THE REV. JOHN CHAMBERS. "For many days my mind has been exercised how I could in the most Christian and modest way reach the eye and ear of a very large number of friends whose solicitude for my restoration to health and continued life has been so marked. I have concluded that a simple card, sent out through the press, from an honest heart, would be acceptable to all. First, then, I owe a debt of undying gratitude to the Ministers of the Prince of Peace, who came like doves to the windows of my tabernacle with the inquiry late and early: 'How is he; any change for the better?' Again my gratitude is due to a large number of God's Israel, who called again and again without any other object than to know whether the light was beginning to burn brighter in the house of sorrow. How Christian-like was this! Then, again, I wish to acknowledge, as best I can, my debt of gratitude to that large class of my fellow-citizens, beginning with the learned jurist and reaching down to the humblest man of toil. In this enumeration I take more than ordinary pleasure in including a large number of the Society of Friends, especially the members of the Twelfth Street Meeting. While memory lasts those fond inquiries of old and young will not be forgotten. Kind words never die. As to my own beloved people I may say of them, as Jesus said of the faithful woman: 'They have done what they could'. There has been nothing left undone to relieve the anxiety of a pastor's heart. The Press, too, has been most kind and generous, for which I thank them. Nor can I pass unnoticed the eminent services of my physician, S. Weir Mitchell, M.D., whose skill and devotion, under God, have brought me into a state of convalescence. Glorious Christianity! How unlike all other systems of religion. JOHN CHAMBERS. Philadelphia, March 28, 1871." On reaching his seventy-sixth year, in 1874, the young people of the congregation planned a delightful surprise, of which he thus told, at the semi-centennial of his pastorate: "They converted these two figures '7--6' into gold dollars, and they presented me the '76' beautifully made up of gold dollars, containing one hundred and eleven in all."
