"The next morning I was at the capitol at a very early hour, attending to some writing. I thought of, and lamented the accident that had befallen Mr. Adams, and had already commenced writing an account of it to a correspondent. At that instant I withdrew my eyes from the paper on which I was writing, and saw Mr. Adams standing a foot or two from me, carefully examining the carpeting. 'Sir,' said he, 'I am looking for that place in the matting that last night tripped me. If it be not fastened down, it may kill some one.' And then he continued his search for the trick-string matting."

Mr. Adams after this accident did not enjoy as sound health as in previous years, yet was more active and vigorous than the majority of those who attain to his age. But on the 20th of November, 1846, he experienced the first blow of the fatal disease which eventually terminated his existence.

On the morning of that day, while sojourning at the residence of his son, in Boston, preparing to depart for Washington, he was walking out with a friend to visit a new Medical College, and was struck with paralysis by the way. This affliction confined him several weeks, when he obtained sufficient strength to proceed to Washington, and enter upon his duties in the House of Representatives. He viewed this attack as the touch of death. An interregnum of nearly four months occurs in his journal. The next entry is under the head of "Posthumous Memoir." After describing his recent sickness, he continues:—"From that hour I date my decease, and consider myself, for every useful purpose, to myself and fellow-creatures, dead; and hence I call this, and what I may hereafter write, a posthumous memoir."

Although he was after this, regular in his attendance at the House of Representatives, yet he did not mingle as freely in debate as formerly. He passed the following summer, as usual, at his seat in Quincy. In November, he left his native town for Washington, to return no more in life!

On Sunday, the 20th of February, 1848, he appeared in unusual health. In the forenoon he attended public worship at the capitol, and in the afternoon at St. John's church. At nine o'clock in the evening he retired with his wife to his library, where she read to him a sermon of Bishop Wilberforce, on Time—"hovering, as he was, on the verge of eternity!" This was the last night he passed beneath his own roof.

Monday, the 21st, he rose at his usual very early hour, and engaged in his accustomed occupations with his pen. An extraordinary alacrity pervaded his movements, and the cheerful step with which he ascended the steps of the capitol was remarked by his attendants. He occupied a portion of the forenoon in composing a few stanzas of poetry, at the request of a friend, and had signed his name twice for members who desired to obtain his autograph.

Mr. Chase had introduced a resolution of thanks to Generals Twiggs, Worth, Quitman, Pillow, Shields, Pearce, Cadwalader, and Smith, for their services in the Mexican war, and awarding them gold medals. Mr. Adams was in his seat, and voted on the two questions preliminary to ordering its engrossment, with an uncommonly emphatic tone of voice. About half past one o'clock, P. M., as the Speaker had risen to put another question to the House, the proceedings were suddenly interrupted by cries of "Stop!—stop!—Mr. Adams!" There was a quick movement towards the chair of Mr. Adams, by two or three members, and in a moment he was surrounded by a large number of Representatives, eagerly inquiring—"What's the matter?"—"Has he fainted?"—"Is he dead?" JOHN QUINCY ADAMS, while faithful at his post, and apparently about to rise to address the Speaker, had sunk into a state of unconsciousness! He had been struck a second time with paralysis. The scene was one of intense excitement. Pallor, anxiety, alarm, were depicted on every countenance. "Take him out,"—"Bring water,"—exclaimed several voices. He had been prevented from falling to the floor by a member from Ohio, whose seat was near his—Mr. Fisher—who received him in his arms. Immediately Mr. Grinnell, one of his colleagues from Massachusetts, was by his side, keeping off a press of anxious friends, and bathing his face with iced water.

"He was immediately lifted into the area in front of the Clerk's table. The Speaker instantly suggested that some gentleman move an adjournment, which being promptly done, the House adjourned. A sofa was brought, and Mr. Adams, in a state of perfect helplessness, though not of entire insensibility, was gently laid upon it. The sofa was then taken up and borne out of the Hall into the Rotunda, where it was set down, and the members of both Houses, and strangers, who were fast crowding around, were with some difficulty repressed, and an open space cleared in its immediate vicinity; but a medical gentleman, a member of the House, (who was prompt, active, and self-possessed throughout the whole painful scene,) advised that he be removed to the door of the Rotunda opening on the east portico, where a fresh wind was blowing. This was done; but the air being chilly and loaded with vapor, the sofa was, at the suggestion of Mr. Winthrop, once more taken up and removed to the Speaker's apartment, the doors of which were forthwith closed to all but professional gentlemen and particular friends."

The features of the dying patriarch were almost as rigid as though in death: but there was a serenity in his countenance which betokened an absence of pain. There were five physicians, members of the House, present, viz.:—Drs. Newell, Fries, Edwards, Jones of Georgia, and Lord. These gentlemen were unremitting in their attentions. Drs. Lindsley and Thomas, of the city, were also immediately called in. Under the advice of the medical gentlemen present, he was cupped, and mustard plasters were applied, which seemed to afford some relief. Reviving a little and recovering consciousness, Mr. Adams inquired for his wife. She was present, but in extreme illness, and suffering the most poignant sorrow. After a few moments' interval he relapsed again into unconsciousness. A correspondent of the New York Express describes as follows the progress of these melancholy events:—

"Half past one o'clock.—Mr. Benton communicated to the Senate the notice of the sudden illness of Mr. Adams, and moved an adjournment of that body.
