I cannot afford the space for numerous individual incidents of interest which occurred at those meetings, but will mention one, which is not likely to be forgotten by some of the witnesses to it, who may perhaps read this page. A stranger came one day, of evident distinction and advanced years, French, though speaking English; I have a vague impression that he was a diplomatist. He had with him a friend. He produced a folded paper or envelope, and asked if the Spirits could tell him what it contained. The answer promptly came, "A piece of the hair of the Emperor Napoleon." This naturally arrested the eager attention of all the company. I trembled with doubt and fear of a failure. The old gentleman opened the paper and held up a small piece of hair, and, with tears in his eyes and quivering lips, said--either he had been one of those who accompanied Napoleon on his voyage to St. Helena, or that he was a friend of the physician who had accompanied him. After this lapse of time I am not certain which, but something was said about the physician. He told how on an occasion of his hair being cut by the barber, the fallen pieces had been religiously gathered up, and this was one of them. Turning to his friend who had come with him, he said, "I did not need this evidence, but this test is evidently intended for you;" and then explained that in the morning his friend, who was an entire unbeliever, had said, in reference to their intended visit to us, that if we were subjected to that test, and if it should be told what were the contents of the envelope, he would be a believer too. I remember that Mr. Greeley and Mr. Ripley, of the _Tribune_, were present. If this should fall under the eye of any survivors of that scene, I should be pleased to hear from them. None present can have forgotten it. There were a number of somewhat similar cases of treasured locks of hair being thus identified by those who had worn them in life, but though there are many whose hair is thus preserved by faithful memories, there has been but one Napoleon the Great. However, I will further add that if there was but one Napoleon I., there was also but one John C. Calhoun. One day a Southern gentleman was at the table, and, having heard of the above incident respecting the great Emperor, produced and laid down his pocket-book, asking to know one thing it contained. "Hair of John C. Calhoun," was the reply. He acknowledged its truth, and exhibited the lock.
