The door was opened by a very old lady, wrinkled and bowed down with age, who invited us to enter. The room was so dark, that, before my eyes were accommodated to the change, I could only see a figure dressed in white, sitting upon the bed and rocking to and fro. This motion was attended by a sound like the click of wooden machinery, which arose, as I afterwards discovered, from the bones, as they worked in their loosened sockets. As we approached, she extended her hand to my companion, and said, in a painful but affectionate voice, "Eliza, I am very glad to see thee;" and then asked my name and place of residence. She had just given me her hand, when a spasm seized her, and it was twitched suddenly from my grasp. It flew some four or five times with the greatest violence against her face, and then, with a sound, which I can only compare to that made by a child who has been sobbing a long time, in catching its breath, she threw up both her arms, and with a deep guttural groan was flung back upon her pillow, with a force inconceivable to one who has not witnessed it. The instant she touched the bed, she uttered that piercing shriek again, and sprung back to her former position, rocking to and fro, with those quick, heart-rending groans which I had heard while standing at the door. It was several minutes before she could speak, and then there was none to answer her. Both my companion and myself were choked with tears. Her poor mother went to the other side of the bed, and smoothed the coverlid, and re-arranged the pillows, looking sadly upon her poor child, writhing in torture which she could not alleviate. I became faint, and trembled with sudden weakness: a cold perspiration stood upon my face. The objects in the room began to swim about me, and I was obliged to take hold of the bedside for support. I have been in our largest hospitals, and have spent hours in going from room to room with the attending physician. I have witnessed there almost every form of human suffering, but I had never beheld any thing to be compared to that now before me. She afterwards told me, as if in apology for her screams, that when she was hurled back upon her pillow, both shoulders were dislocated, and as they sprung back into their sockets, the pain was far beyond endurance, and extorted from her these shrieks.
